SLIDE FASTENER PULL TAB WITH PULL TAB AUXILIARY PART ROTATABLY ASSEMBLED AND DISASSEMBLED, AND SLIDE FASTENER SLIDER

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on and claims priority under 35 USC § 119 from Chinese Utility Model application No. 202420169063.9 filed on Jan. 23, 2024, the contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to the technical field of slide fasteners, in particular to a slide fastener pull tab with a pull tab auxiliary part rotatably assembled and disassembled, and a slide fastener slider including the slide fastener pull tab.

BACKGROUND

At present, slide fasteners are widely used in daily necessities such as clothes, bags, tents, bedding, and the like, and the slide fasteners are used to combine or separate items.

In general, a slide fastener mainly includes a pair of cloth tapes, chains fixed on inner edges of the cloth tapes, and a slider. The slider includes a slider main body attached to the chains, and a pull tab attached to a surface of the slider main body. By holding the pull tab and pulling the slider main body along a length direction of the slide fastener, the pair of chains are engaged or separated, and the slide fastener is correspondingly closed or opened. In order to enhance the design sense of the slide fastener, some slide fasteners in the related art are additionally provided with a pull tab auxiliary part. The pull tab auxiliary part is detachably attached to the pull tab of the slide fastener slider, and the pull tab auxiliary part can not only improve the convenience of pulling the slider, but also enrich the design sense of the slide fastener.

For example, in a separated part combination pull tab disclosed in Chinese Utility Model Patent No. CN217446885U, the detachable connection between a rear pull tab and a front pull tab is implemented by fastening a connecting column on the rear pull tab in a connecting hole on the front pull tab. However, an outer diameter of an end portion of the connecting column of the rear pull tab is much greater than a hole diameter of the connecting hole, resulting in that a large force is required when pressing the connecting column into the connecting hole, which also makes the attachment operation of pressing the connecting column into the connecting hole difficult.

For another example, in a slide fastener pull tab disclosed in Chinese invention patent with the authorization announcement number of CN110811084B, when a pull tab auxiliary part is attached, a pull tab auxiliary portion of the pull tab auxiliary part is passed through an attachment hole on the pull tab main body, and then a neck portion of an end portion of the pull tab auxiliary portion is held in the attachment hole of the pull tab main body through limiting a position of a head portion. This makes the attachment of the pull tab auxiliary part easier. However, the pull tab auxiliary portion needs to pass through the attachment hole at the time of attachment, and another end, away from the neck portion, of the pull tab auxiliary portion is a holding portion. Thus, the shape of the holding portion is limited by the attachment hole on the pull tab main body, making it difficult to design the holding portion to have a richer appearance, which also limits the appearance of the pull tab auxiliary part.

In view of the above disadvantages of the related art, the technical problem to be solved by the present invention is to provide a slide fastener pull tab with a pull tab auxiliary part rotatably assembled and disassembled, which not only facilitates the attachment of the pull tab auxiliary part, but also does not limit the appearance design of the pull tab auxiliary part.

SUMMARY

According to one aspect of the present invention, a slide fastener pull tab with a pull tab auxiliary part is configured to be rotatably assembled and disassembled. The slide fastener pull tab includes: a pull tab main body; and the pull tab auxiliary part. The pull tab main body is provided with an attachment hole penetrating therethrough and an auxiliary part attachment portion located on an outer periphery of the attachment hole.

When the combination of the technical solutions appears to be contradictory or cannot be implemented, it should be considered that the combination of the technical solutions does not exist and is not within the protection scope claimed by the present application.

The present application relates to the technical field of slide fasteners. For convenience of description, in the following embodiments, directions are defined as follows. A length direction of a slide fastener is defined as a front-rear direction, a width direction of the slide fastener is defined as a left-right direction, and a thickness direction of the slide fastener is defined as an up-down direction. The slide fastener mainly includes a pair of cloth tapes located side by side on left and right sides, chains fixed on inner edges of cloth tapes and extending forward and rearward, and a slide fastener slider. The slide fastener slider can be attached to the chains in a front-rear sliding mode. When the slide fastener slider is moved forward, the pair of chains are engaged, and thus the slide fastener is closed, and when the slide fastener slider is moved rearward, the pair of chains are separated, and thus the slide fastener is opened.

The present invention mainly relates to a slide fastener slider and a slide fastener pull tab for the slide fastener slider. A length direction, width direction and thickness direction of the slide fastener slider correspond to the length direction, width direction and thickness direction of the slide fastener, respectively, and a length direction, width direction and thickness direction of the slide fastener pull tab also correspond the length direction, width direction and thickness direction of the slide fastener, respectively. Based on this, in the views shown in FIG. 1, FIG. 4 or FIG. 7, an upper side of the paper is a front direction, a lower side of the paper is a rear direction, a left side of the paper is a left direction, a right side of the paper is a right direction, a front side of the paper is an upper direction, and a back side of the paper is a lower direction.

As shown in FIG. 1 to 3, or as shown in FIGS. 11 to 13, the slide fastener slider according to the present invention includes a slider main body 40 and a slide fastener pull tab. The slider main body 40 includes an upper blade 41 and a lower blade 42 disposed opposite to each other up and down, an element passage formed between the upper blade 41 and the lower blade 42, and a pull tab attachment column portion 43 fixed to an upper surface of the upper blade 41. A part of elements on chains are accommodated in the element passage. The slide fastener pull tab includes a pull tab main body 10 and a pull tab auxiliary part 20. A front end of the pull tab main body 10 is connected to the pull tab attachment column portion 43, and thus the slide fastener pull tab is integrally attached to an upper surface of the slider main body 40. A rear end of the pull tab main body 10 is detachably connected to the pull tab auxiliary part 20, and thus the pull tab auxiliary part 20 can be replaced.

As shown in FIGS. 4 and 5, or as shown in FIGS. 14 and 15, a front section of the pull tab main body 10 is a slider attachment portion 13 to be connected to the pull tab attachment column portion 43 on the slider main body 40. Preferably, the slider attachment portion 13 of the pull tab main body 10 is provided with a column portion connecting hole 14 penetrating therethrough, and the column portion connecting hole 14 penetrates the pull tab main body 10 along a thickness direction of the pull tab main body 10. The slider attachment portion 13 of the pull tab main body 10 is fitted into the pull tab attachment column portion 43 of the slider main body 40 through the column portion connecting hole 14, as shown in FIG. 1 to 3, or as shown in FIGS. 11 to 13, and thus the pull tab main body 10 is attached to the slider main body 40.

In particular, the slide fastener pull tab of the present application is a slide fastener pull tab with the pull tab auxiliary part 20 rotatably assembled and disassembled. As shown in FIGS. 4 and 5, or as shown in FIGS. 14 and 15, a rear section of the pull tab main body 10 is an auxiliary part attachment portion 12 to be connected to the pull tab auxiliary part 20. The auxiliary part attachment portion 12 of the pull tab main body 10 is provided with an attachment hole 11 penetrating therethrough, and the auxiliary part attachment portion 12 is located at a periphery of the attachment hole 11. The attachment hole 11 does not have a perfect circle shape, for example, the attachment hole 11 has an ellipse shape, a rectangular shape, a waist-like shape, a trapezoidal shape, and the like, and the attachment hole 11 has different hole diameters in at least two intersecting directions. As shown in FIG. 7 to 10, or as shown in FIGS. 17 to 20, the pull tab auxiliary part 20 includes an auxiliary part main body 21 extending forward and rearward, an auxiliary part column portion 22 extending downward from a front end of the auxiliary part main body 21, and an auxiliary part head portion 23 fixed at a lower end of the auxiliary part column portion 22. The auxiliary part head portion 23 is fixed at an outer end of the auxiliary part column portion 22. The auxiliary part column portion 22 has a cylindrical structure or a prism structure, and the auxiliary part head portion 23 does not have a perfect circle shape, for example, the auxiliary part head portion 23 has an ellipse shape, a rectangular shape, a waist-like shape, a trapezoidal shape, and the like, and the auxiliary part head portion 23 has different lengths in at least two intersecting directions. The auxiliary part head portion 23 is an elastically deformable body. When a length direction of the auxiliary part head portion 23 is consistent with a length direction of the attachment hole 11, the attachment hole 11 of the pull tab main body 10 allows the elastically deformable auxiliary part head portion 23 of the pull tab auxiliary part 20 to pass through. The attachment hole 11 of the pull tab main body 10 also accommodates the auxiliary part column portion 22 of the pull tab auxiliary part 20 and allows the auxiliary part column portion 22 to rotate.

Based on the pull tab main body 10 and the pull tab auxiliary part 20 of the above structure, the pull tab main body 10 and the pull tab auxiliary part 20 can be separated and combined. Specifically, when the pull tab auxiliary part 20 is attached, as shown in FIG. 21, first, the length direction of the auxiliary part head portion 23 is made consistent with the length direction of the attachment hole 11, and the auxiliary part head portion 23 is aligned with the attachment hole 11. Then, the auxiliary part head portion 23 is pressed with force. Since the auxiliary part head portion 23 can be elastically deformed and the length direction of the auxiliary part head portion 23 is consistent with the length direction of the attachment hole 11, at this time, a maximum length direction of the auxiliary part head portion 23 is consistent with a maximum hole diameter direction of the attachment hole 11, the auxiliary part head portion 23 can be easily pressed into the attachment hole 11 by pressing the auxiliary part head portion 23 with force, and thus the auxiliary part head portion 23 can easily pass through the attachment hole 11. After that, the pull tab auxiliary part 20 whose auxiliary part head portion 23 passes through the attachment hole 11 is rotated by an angle such that the length direction of the auxiliary part head portion 23 intersects with the length direction of the attachment hole 11. Since neither the attachment hole 11 nor the auxiliary part head portion 23 has a perfect circle shape, after rotation, at least two ends in the maximum length direction of the auxiliary part head portion 23 abuts against the auxiliary part attachment portion 12, that is, after rotation, the dimension of the auxiliary part head portion 23 in the length direction is greater than a hole diameter of the attachment hole 11 in this length direction, and thus the part of the auxiliary part head portion 23 protruding from the auxiliary part column portion 22 abut against the auxiliary part attachment portion 12, restricting the auxiliary part head portion 23 from being separated from the attachment hole 11, and reliably connecting the pull tab auxiliary part 20 to the pull tab main body 10. On the other hand, when the pull tab auxiliary part 20 is disassembled, as shown in FIG. 22, the pull tab auxiliary part 20 is rotated until the length direction of the auxiliary part head portion 23 is consistent with the length direction of the attachment hole 11, and then the auxiliary part head portion 23 is pulled out from the attachment hole 11 by applying force. At this time, since the maximum length direction of the auxiliary part head portion 23 is consistent with the maximum hole diameter direction of the attachment hole 11, and the auxiliary part head portion 23 can be elastically deformed, the auxiliary part head portion 23 can be easily pulled out from the attachment hole 11 when force is applied to pull out the pull tab auxiliary part 20, and the pull tab auxiliary part 20 can be detached from the pull tab main body 10.

Therefore, in the slide fastener pull tab of the present application, the pull tab main body 10 and the pull tab auxiliary part 20 are detachably connected, and different pull tab auxiliary parts 20 can be replaced. In particular, in the present application, the operation of pressing the auxiliary part head portion 23 into the attachment hole 11 is extremely easy. After that, the attachment of the pull tab auxiliary part 20 can be completed only by rotating the pull tab auxiliary part 20, making the replacement of the pull tab auxiliary part 20 extremely easy. In this way, the present application not only facilitates the attachment and replacement of the pull tab auxiliary part 20, but also prevents the auxiliary part main body 21 from passing through the attachment hole 11, and thus the attachment hole 11 does not cause any constraints on the auxiliary part main body 21, and effectively prevents the attachment hole 11 from limiting the appearance design of the pull tab auxiliary part 20. This allows the present application to use pull tab auxiliary parts 20 of any appearance, greatly improving and enriching the appearance design of the slide fastener pull tab, and ultimately improving and enriching the design sense of slide fasteners. In addition, both the auxiliary part column portion 22 and the auxiliary part head portion 23 are disposed on a lower side, that is, a back surface side, of the auxiliary part main body 21, and thus a front surface structure of the slide fastener pull tab is simple and clean, which is beneficial to improving the aesthetics of the slide fastener slider.

Further, the length direction of the attachment hole 11 may be consistent with a length direction of the pull tab main body 10, or may be consistent with a width direction of the pull tab main body 10, or may intersect both the length direction and the width direction of the pull tab main body 10. The slide fastener pull tab has a number of embodiments based on different configurations of the attachment hole 11 and the auxiliary part attachment portion 12 on the pull tab main body 10 and different configurations of the auxiliary part head portion 23 on the pull tab auxiliary part 20. Two preferred embodiments of the slide fastener pull tab are provided below.

[First Embodiment of Slide Fastener Pull Tab]

In a first embodiment of the slide fastener pull tab, the arrangement structure of the attachment hole 11 on the pull tab main body 10 is preferably as follows. As shown in FIGS. 4 and 5, the attachment hole 11 is a rectangular hole, a length direction of the attachment hole 11 is consistent with a width direction of the pull tab main body 10, and both directions are left-right directions, that is, the attachment hole 11 extends leftward and rightward along the width direction of the pull tab main body 10, and the attachment hole 11 penetrates through the pull tab main body 10 along a thickness direction of the pull tab main body 10. The four corners of the rectangular attachment hole 11 are arc segments 113. The rectangular attachment hole 11 has a rectangular hole wall contour, and more specifically, the rectangular attachment hole 11 has a pair of transverse straight hole walls 111 disposed side by side on front and rear sides and a pair of longitudinal straight hole walls 112 disposed side by side on left and right sides. The transverse straight hole walls 111 extend straightly leftward and rightward along the length direction of the attachment hole 11, the longitudinal straight hole walls 112 extend straightly frontward and rearward along a width direction of the attachment hole 11, and the adjacent transverse straight hole wall 111 and longitudinal straight hole wall 112 are in transition connection through the arc segment 113. Therefore, the attachment hole 11 has the largest hole diameter between the pair of longitudinal straight hole walls 112 (that is, in the left-right direction), and the attachment hole 11 has the smallest hole diameter between the pair of transverse straight hole walls 111 (that is, in the front-rear direction).

Preferably, when a length direction of the auxiliary part head portion 23 is consistent with the length direction of the attachment hole 11 and the auxiliary part head portion 23 passes through the attachment hole 11, a gap exists between an outer peripheral surface of the auxiliary part column portion 22 and the pair of transverse straight hole walls 111 of the attachment hole 11, and a gap also exists between an outer peripheral surface of the auxiliary part column portion 22 and the pair of longitudinal straight hole walls 112 of the attachment hole 11, thereby facilitating the subsequent rotation of the pull tab auxiliary part 20, and also facilitating the attachment operation of the pull tab auxiliary part 20.

Further, as shown in FIGS. 1 to 3 and FIGS. 8 to 10, the auxiliary part head portion 23 extends straightly frontward and rearward along a length direction of the auxiliary part main body 21, and the length direction of the auxiliary part head portion 23, the length direction of the auxiliary part main body 21, and a length direction of the pull tab main body 10 are all in the front-rear direction. The dimension of the auxiliary part head portion 23 in the length direction is greater than the hole diameter of the attachment hole 11 in the length direction of the pull tab main body 10. In this way, when the pull tab auxiliary part 20 is attached, as shown in FIG. 21, the pull tab auxiliary part 20 is first in a horizontal state, and the length direction of the auxiliary part head portion 23 is consistent with the length direction of the attachment hole 11. Then, the auxiliary part head portion 23 is pressed downward through the attachment hole 11. After that, the pull tab auxiliary part 20 is rotated rearward by 90°, and thus the auxiliary part head portion 23 can well abut against a surface of the auxiliary part attachment portion 12, thereby improving the connection reliability between the pull tab auxiliary part 20 and the pull tab main body 10.

In this state, the auxiliary part main body 21 of the pull tab auxiliary part 20 extends rearward in the length direction of the pull tab main body 10, and thus the overall appearance of the slide fastener pull tab has excellent consistency, which is beneficial to improving the integrity of the slide fastener pull tab and improving the aesthetic appearance of the slide fastener pull tab.

Further, as shown in FIGS. 9 and 10, front and rear sides of the auxiliary part head portion 23 each have a first protruding portion 231 extending outward from the auxiliary part column portion 22 along the length direction of the auxiliary part head portion 23 (that is, along the length direction of the auxiliary part main body 21), and left and right sides of the auxiliary part head portion 23 each have a second protruding portion 232 extending outward from the auxiliary part column portion 22 along the width direction of the auxiliary part head portion 23 (that is, along a width direction of the auxiliary part main body 21). In other words, the first protruding portion 231 is provided at an end portion of the auxiliary part head portion 23 in the length direction thereof, and the second protruding portion 232 is provided at an end portion of the auxiliary part head portion 23 in the width direction thereof. In the front-rear direction, extension lengths of the two first protruding portions 231 with respect to the auxiliary part column portion 22 are W11 and W12 respectively. In the left-right direction, an extension length of each of the second protruding portions 232 with respect to the auxiliary part column portion 22 is W2. The extension lengths W11 and W12 of the first protruding portions 231 are both greater than the extension length W2 of the second protruding portion 232. In this way, when the length direction of the auxiliary part head portion 23 is consistent with the length direction of the attachment hole 11, the dimension of the auxiliary part head portion 23 in the width direction of the attachment hole 11 can be reduced in this state, and thus the auxiliary part head portion 23 can pass through the attachment hole 11 more easily when the auxiliary part head portion 23 is pressed. Further, the extension lengths W11 and W12 of the first protruding portions 231 and the extension length W2 of the second protruding portion 232 should satisfy the following. When the auxiliary part head portion 23 is pressed downward, the auxiliary part head portion 23 can easily pass through the attachment hole 11. After the auxiliary part head portion 23 passes downward through the attachment hole 11 and the pull tab auxiliary part 20 is rotated rearward by 90°, the length direction of the auxiliary part head portion 23 is perpendicular to the length direction of the attachment hole 11, and at this time, a large part of the first protruding portions 231 abuts against the auxiliary part attachment portion 12, thereby reliably preventing the auxiliary part head portion 23 from being separated from the attachment hole 11.

Preferably, since the auxiliary part head portion 23 is disposed close to the front end of the auxiliary part main body 21, the first protruding portion 231 at a front end of the auxiliary part head portion 23 is closer to an outer edge of the auxiliary part main body 21 than the first protruding portion 231 at a rear end of the auxiliary part head portion 23. In this way, the first protruding portion 231 at the front end of the auxiliary part head portion 23 is defined as an outer protruding portion 233, the first protruding portion 231 at the rear end of the auxiliary part head portion 23 is defined as an inner protruding portion 234, an extension length of the outer protruding portion 233 extending forward is W11, and an extension length of the inner protruding portion 234 extending rearward is W12. In the first embodiment of the slide fastener pull tab, as shown in FIGS. 9 and 10, the auxiliary part head portion 23 has an asymmetric structure. The extension length W11 of the outer protruding portion 233 on a front side of the auxiliary part head portion 23 is smaller than the extension length W12 of the inner protruding portion 234 on a rear side of the auxiliary part head portion 23, but the extension lengths of the second protruding portions 232 on the left and right sides of the auxiliary part head portion 23 are equal.

Further, as shown in FIG. 5 and FIG. 6, a first fixing groove 15 and a second fixing groove 16 are provided on a back surface of the auxiliary part attachment portion 12 of the pull tab main body 10, and the first fixing groove 15 and the second fixing groove 16 are respectively located on front and rear sides of the attachment hole 11 along the length direction of the pull tab main body 10. In other words, the first fixing groove 15 and the second fixing groove 16 are respectively located on outer peripheral sides of the two transverse straight hole walls 111. After the auxiliary part head portion 23 is pressed downward from an upper side of the pull tab main body 10 through the attachment hole 11 and rotated rearward by 90°, the length direction of the auxiliary part head portion 23 and the length direction of the auxiliary part main body 21 are consistent with the length direction of the pull tab main body 10, the length direction of the auxiliary part head portion 23 is perpendicular to the length direction of the attachment hole 11, and the two first protruding portions 231 at the front and rear ends of the auxiliary part head portion 23 are respectively clamped in the first fixing groove 15 and the second fixing groove 16, that is, the outer protruding portion 233 at the front end is clamped in the first fixing groove at a front side of the attachment hole 11, and the inner protruding portion 234 at the rear end is clamped in the second fixing groove 16 at a rear side of the attachment hole 11. Through the clamping fit of the first fixing groove 15 and the outer protruding portion 233 and the clamping fit of the second fixing groove 16 and the inner protruding portion 234, the reliability and stability of the pull tab auxiliary part 20 attached to the pull tab main body 10 are effectively improved, the pull tab auxiliary part 20 is reliably prevented from being accidentally separated from the pull tab main body 10, and the pull tab auxiliary part 20 is reliably prevented from rotating randomly in the pull tab main body 10.

Further, as shown in FIGS. 5 and 6, at least one first fixing buckle 30 is fixed on the back surface of the auxiliary part attachment portion 12 of the pull tab main body 10. The first fixing buckle 30 protrudes downward from the auxiliary part attachment portion 12 along the thickness direction of the pull tab main body 10, and is located on an outer peripheral side of the first fixing groove 15 and/or the second fixing groove 16. In the present embodiment, as shown in FIGS. 5 and 6, there are two first fixing buckles 30, and the two first fixing buckles are symmetrically located on the outer peripheral side of the first fixing groove 15 in the left-right direction. When the two first protruding portions 231 at the front and rear ends of the auxiliary part head portion 23 are respectively clamped in the first fixing groove 15 and the second fixing groove 16, the pair of first fixing buckles 30 abut against left and right sides of an outer periphery of the auxiliary part head portion 23 respectively, which further limits the random rotation of the auxiliary part head portion 23, and more reliably improves the reliability and stability of the pull tab auxiliary part 20 attached to the pull tab main body 10.

Further, as shown in FIGS. 5 and 6, a groove wall contour of the first fixing groove and an outer peripheral contour of the outer protruding portion 233 match with each other and are both semicircular. When the pull tab auxiliary part 20 is disassembled, the semicircular first fixing groove 15 and the outer protruding portion 233 facilitate the outer protruding portion 233 to be rotated and separated from the first fixing groove 15, which also facilitate the disassembly operation of the pull tab auxiliary part 20. In the front-rear direction, a length of the inner protruding portion 234 is greater than a length of the second fixing groove 16, a front end of the second fixing groove 16 extends forward to a rear edge of the attachment hole 11, and a rear end of the second fixing groove 16 penetrates rearward through a rear edge of the auxiliary part attachment portion 12. Thus, the second fixing groove 16 has a front-rear through structure, which facilitates the processing of the second fixing groove 16 on the back surface of the auxiliary part attachment portion 12. In particular, after the attachment of the pull tab auxiliary part 20 is completed, the inner protruding portion 234 is clamped in the second fixing groove 16. Since the length of the inner protruding portion 234 is greater than the length of the second fixing groove 16, a part of the inner protruding portion 234 inevitably extends rearward from the pull tab main body 10, as shown in FIG. 3. Thus, an area of the abutting portion of the inner protruding portion 234 and the second fixing groove 16 is increased, and the reliability and stability of the pull tab auxiliary part 20 attached to the pull tab main body 10 are improved.

Preferably, as shown in FIG. 8, in the direction from the outer protruding portion 233 to the inner protruding portion 234, a width of the auxiliary part head portion 23 in the left-right direction gradually increases, and thus a left edge and a right edge of the auxiliary part head portion 23 are both inclined edges which are farther away from a central axis of the auxiliary part head portion 23 as approaching the rear. Groove walls of the second fixing groove 16 abut against left and right sides of the inner protruding portion 234, and groove walls of the second fixing groove 16 are a pair of second inclined groove walls 17 symmetrically disposed left and right. The second inclined groove walls 17 extend in an inclined manner that is farther away from a central axis of the pull tab main body 10 as approaching the rear. Therefore, after the attachment of the pull tab auxiliary part 20 is completed, as shown in FIG. 3, the left edge of the auxiliary part head portion 23 has an inclination direction consistent with that of the second inclined groove wall 17 on the left side of the second fixing groove 16 and is in abutting fit with the second inclined groove wall 17, and the right edge of the auxiliary part head portion 23 has an inclination direction consistent with that of the second inclined groove wall 17 on the right side of the second fixing groove 16 and is in abutting fit with the second inclined groove wall 17, which effectively limits left and right shaking of the inner protruding portion 234, and thus left and right shaking of the pull tab auxiliary part 20 is limited.

[Second Embodiment of Slide Fastener Pull Tab]

The difference between a second embodiment of the slide fastener pull tab and the first embodiment of the slide fastener pull tab lies in that the shape of the attachment hole 11, the structure on the back surface side of the auxiliary part attachment portion 12, and the shape of the auxiliary part head portion 23 are different.

Specifically, in the second embodiment of the slide fastener pull tab, as shown in FIGS. 14 and 15, the attachment hole 11 is a waist-like-shaped hole. The waist-like-shaped attachment hole 11 has a hole wall contour similar to an ellipse, and more specifically, the waist-like-shaped attachment hole 11 has a pair of transverse straight hole walls 111 disposed side by side on front and rear sides and a pair of arc hole walls 114 disposed side by side on left and right sides. The transverse straight hole walls 111 extend straightly leftward and rightward along a length direction of the attachment hole 11, and the pair of arc hole walls 114 are located at left and right ends of the attachment hole 11 in the length direction and connected between a pair of transverse straight hole walls 111. Therefore, the attachment hole 11 has the largest hole diameter between the pair of arc hole walls 114 (that is, in the left-right direction), and the attachment hole 11 has the smallest hole diameter between the pair of transverse straight hole walls 111 (that is, in the front-rear direction). As shown in FIG. 18, an outer peripheral contour of the auxiliary part head portion 23 is similar to an ellipse. When a length direction of the auxiliary part head portion 23 is consistent with the length direction of the attachment hole 11, a hole wall contour of the attachment hole 11 and the outer peripheral contour of the auxiliary part head portion 23 match with each other, and thus when the auxiliary part head portion 23 is pressed downward, the auxiliary part head portion 23 can easily pass through the attachment hole 11. Further, after the pull tab auxiliary part 20 is rotated rearward by 90°, the auxiliary part head portion 23 can well abut against a surface of the auxiliary part attachment portion 12, and the connection reliability between the pull tab auxiliary part 20 and the pull tab main body 10 is improved.

Preferably, in the second embodiment of the slide fastener pull tab, as shown in FIGS. 19 and 20, the auxiliary part head portion 23 has a symmetrical structure, extension lengths of the first protruding portions 231 on front and rear sides of the auxiliary part head portion 23 are equal, and extension lengths of the second protruding portions 232 on left and right sides of the auxiliary part head portion 23 are equal.

Further, as shown in FIGS. 15 and 16, a pair of second fixing buckles 50 protruding downward along a thickness direction of the pull tab main body 10 is fixed on a back surface of the auxiliary part attachment portion 12 of the pull tab main body 10, and the pair of second fixing buckles 50 are located on front and rear sides of the attachment hole 11 and are symmetrically disposed. Each of the second fixing buckles 50 is provided with a third fixing groove 51 at an intermediate position in the left-right direction, the third fixing groove 51 is formed on a lower surface of the auxiliary part attachment portion 12, and there are two third fixing grooves 51 on the back surface of the auxiliary part attachment portion 12, which are symmetrical from front to rear. In this way, the pair of second fixing buckles 50 and the attachment hole 11 form a cross buckle structure formed on a back surface of the pull tab main body 10, and the two third fixing grooves 51 are respectively located on outer peripheral sides of the two transverse straight hole walls 111. When the auxiliary part head portion 23 is pressed downward from an upper side of the pull tab main body 10 through the attachment hole 11 and rotated rearward by 90°, the length direction of the auxiliary part head portion 23 is consistent with a length direction of the pull tab main body 10, the length direction of the auxiliary part head portion 23 is perpendicular to the length direction of the attachment hole 11, and the first protruding portions 231 at both ends of the auxiliary part head portion 23 in the length direction thereof are respectively clamped into the pair of third fixing grooves 51. Through the clamping fit of the first protruding portions 231 and the third fixing grooves 51, the reliability and stability of the pull tab auxiliary part 20 attached to the pull tab main body 10 are effectively improved. Therefore, in the second embodiment of the slide fastener pull tab, the auxiliary part head portion 23 is fixed by the pair of second fixing buckles 50, which reliably prevents the pull tab auxiliary part 20 from being accidentally separated from the pull tab main body 10.

Preferably, as shown in FIG. 15, each of the third fixing grooves 51 has a pair of first inclined groove walls 52 symmetrically disposed on left and right sides along a width direction of the pull tab main body 10, and the first inclined groove walls 52 extend in an inclined manner such that the farther away from the attachment hole 11, the closer to a central axis of the pull tab main body 10. As shown in FIG. 18, each of the first protruding portions 231 has a pair of inclined surfaces 24 on an outer periphery thereof. When the first protruding portion 231 is clamped in the third fixing groove 51, or in other words, when a length direction of the pull tab auxiliary part 20 is consistent with the length direction of the pull tab main body 10, as shown in FIG. 12, the inclined surfaces 24 have an inclination direction consistent with an inclination direction of the first inclined groove walls 52 and are in abutting fit with the first inclined groove walls 52 to limit the first protruding portion 231 to shake in the width direction of the pull tab main body 10. Further, when the pull tab auxiliary part 20 is detached from the pull tab main body 10, the inclined first inclined groove walls 52 facilitate the first protruding portions 231 to be rotated and separated from the third fixing grooves 51, thereby facilitating the disassembly of the pull tab auxiliary part 20.

Preferably, in the case where the pull tab auxiliary part 20 is attached, when the auxiliary part head portion 23 is pressed downward through the attachment hole 11 but the pull tab auxiliary part 20 is not rotated, the pair of second fixing buckles 50 abut against an outer peripheral side of the inclined surfaces 24 at an outer periphery of the auxiliary part head portion 23 to limit the random rotation of the pull tab auxiliary part 20 at this time, and thus the pull tab auxiliary part 20 can rotate only under the force applied by a user.

Further, in the above two embodiments of the slide fastener pull tab, an outer peripheral surface of an outer end of the auxiliary part head portion 23 is provided with an attachment guide inclined surface (not shown) extending in an inclined manner such that the farther away from the auxiliary part column portion 22, the closer to a central axis of the auxiliary part head portion 23. In this way, when the pull tab auxiliary part 20 is attached, the inclined attachment guide inclined surface facilitates the pressing of the auxiliary part head portion 23 through the attachment hole 11, which makes the attachment operation of the pull tab auxiliary part 20 more convenient.

Further, in the above two embodiments of the slide fastener pull tab, as shown in FIGS. 8 and 9, or as shown in FIGS. 18 and 19, a rear end of a back surface of the auxiliary part main body 21 is provided with a slightly downward protruding friction-increasing rib 25, which can increase the friction between the auxiliary part main body 21 and fingers of a user when the user holds the rear end of the auxiliary part main body 21 and pulls the slide fastener slider forward and rearward, so as to play an anti-skid role. At the same time, as shown in FIG. 9 or FIG. 19, the intermediate portion of the auxiliary part main body 21 is provided with an inclined extension section 211, and the more the inclined extension section 211 extends rearward, the more the inclined extension section 211 is inclined upward. A front section of the auxiliary part main body 21 on a front side of the inclined extension section 211 and a rear section of the auxiliary part main body 21 on a rear side of the inclined extension section 211 extend straightly frontward and rearward, and thus the rear section of the auxiliary part main body 21 is far away from a surface of a slide fastener, thereby facilitating the user to better hold the auxiliary part main body 21.

Further, the pull tab main body 10 having the above structure is a metal part of an integrated structure. In the present embodiment, the pull tab main body 10 is a zinc alloy part, and thus the pull tab main body 10 has good structural strength and is durable. The pull tab auxiliary part 20 having the above structure is a plastic part of an integrated structure, for example, the pull tab auxiliary part 20 may be a hard plastic part, a soft plastic part, a rubber part or a resin part, which is convenient to manufacture and has low cost, and pull tab auxiliary parts 20 with different shapes and colors can be easily designed at low cost. Combined with the detachable structure of the pull tab auxiliary part 20 on the pull tab main body 10, a user can conveniently replace different pull tab auxiliary parts 20, and the design sense of slide fasteners is enriched. In addition, in the process of assembling and disassembling the pull tab auxiliary part 20, even if the pull tab auxiliary part 20 is damaged, or even if the pull tab auxiliary part is damaged after being used for a period of time, there is no significant impact due to the low cost of the pull tab auxiliary part 20.

As described above, the present invention provides a slide fastener pull tab with a pull tab auxiliary part configured to be rotatably assembled and disassembled, the slide fastener pull tab including:

- a pull tab main body; and
- the pull tab auxiliary part, in which
- the pull tab main body is provided with an attachment hole penetrating therethrough and an auxiliary part attachment portion located on an outer periphery of the attachment hole,
- the pull tab auxiliary part includes an auxiliary part main body, an auxiliary part column portion extending from the auxiliary part main body, and an auxiliary part head portion fixed at an outer end of the auxiliary part column portion,
- the auxiliary part head portion is an elastically deformable body,
- the attachment hole has different hole diameters in at least two intersecting directions,
- the auxiliary part head portion has different lengths in at least two intersecting directions,
- the auxiliary part column portion is configured to be rotatably accommodated in the attachment hole,
- when a length direction of the auxiliary part head portion is consistent with a length direction of the attachment hole, the attachment hole allows the elastically deformable auxiliary part head portion to pass therethrough, and
- when the pull tab auxiliary part whose auxiliary part head portion passes through the attachment hole is rotated until the length direction of the auxiliary part head portion intersects with the length direction of the attachment hole, the auxiliary part head portion abuts against the auxiliary part attachment portion.

In the present application, neither the attachment hole nor the auxiliary part head portion is set to a perfect circle shape, and thus the attachment hole has different hole diameters in at least two intersecting directions, and the auxiliary part head portion has different lengths in at least two intersecting directions. Therefore, the attachment hole has a larger hole diameter in the length direction thereof, and the auxiliary part head portion has a larger length in the length direction thereof. In this way, when the length direction of the auxiliary part head portion is consistent with the length direction of the attachment hole, combined with the elastic deformation characteristic of the auxiliary part head portion, the auxiliary part head portion can be easily and conveniently pressed into the attachment hole, and thus the auxiliary part head portion easily passes through the attachment hole. Then, the pull tab auxiliary part is rotated by an angle such that the length direction of the auxiliary part head portion intersects with the length direction of the attachment hole. At this time, the auxiliary part head portion abuts against the auxiliary part attachment portion to limit the separation of the auxiliary part head portion from the attachment hole, and thus the pull tab auxiliary part is reliably connected to the pull tab main body. Therefore, in the present application, the operation of pressing the auxiliary part head portion into the attachment hole is extremely easy, which not only facilitates the attachment and replacement of the pull tab auxiliary part, but also does not cause any constraints on the auxiliary part main body by the attachment hole, and does not limit the appearance design of the pull tab auxiliary part. This enables the present application to use the pull tab auxiliary part with any appearance, greatly improving and enriching the design of the slide fastener pull tab, and ultimately improving and enriching the design sense of slide fasteners.

Further, the arrangement structure of the attachment hole on the pull tab main body is preferably as follows. The attachment hole is a waist-like-shaped hole or a rectangular hole. The attachment hole extends straightly along a width direction of the pull tab main body, that is, the length direction of the attachment hole is consistent with the width direction of the pull tab main body, and the attachment hole penetrates through the pull tab main body along a thickness direction of the pull tab main body.

Preferably, due to the waist-like-shaped hole structure or the rectangular hole structure of the attachment hole, a hole wall of the attachment hole includes a pair of transverse straight hole walls extending along the width direction of the pull tab main body. When the length direction of the auxiliary part head portion is consistent with the length direction of the attachment hole and the auxiliary part head portion passes through the attachment hole, a gap exists between an outer peripheral surface of the auxiliary part column portion and the pair of transverse straight hole walls of the attachment hole, thereby facilitating the subsequent rotation of the pull tab auxiliary part, and also facilitating the attachment operation of the pull tab auxiliary part.

Further, the length direction of the auxiliary part head portion, a length direction of the auxiliary part main body and a length direction of the pull tab main body are consistent. After the auxiliary part head portion is pressed through the attachment hole, when the pull tab auxiliary part is rotated until the length direction thereof is consistent with the length direction of the pull tab main body, the auxiliary part head portion can well abut against a surface of the auxiliary part attachment portion, and the connection reliability between the pull tab auxiliary part and the pull tab main body is improved. In this state, the auxiliary part main body of the pull tab auxiliary part extends along the length direction of the pull tab main body, and thus the overall appearance of the slide fastener pull tab has excellent consistency, which is beneficial to improving the integrity of the slide fastener pull tab and improving the aesthetic appearance of the slide fastener pull tab.

Further, the auxiliary part head portion has first protruding portions extending outward from the auxiliary part column portion along the length direction of the auxiliary part main body, and a second protruding portion extending outward from the auxiliary part column portion along a width direction of the auxiliary part main body, and an extension length of each of the first protruding portions is greater than an extension length of the second protruding portion. When the length direction of the auxiliary part head portion intersects with the length direction of the attachment hole, the first protruding portions abut against the auxiliary part attachment portion, thereby reliably preventing the auxiliary part head portion from separating from the attachment hole.

Further, a first fixing groove and a second fixing groove are provided on a surface of the auxiliary part attachment portion of the pull tab main body. The first fixing groove and the second fixing groove are located on both sides of the attachment hole along a length direction of the pull tab main body. When the pull tab auxiliary part whose auxiliary part head portion passes through the attachment hole is rotated until the length direction of the auxiliary part head portion is consistent with the length direction of the pull tab main body, the length direction of the auxiliary part head portion intersects with the length direction of the attachment hole, and the two first protruding portions at both ends in the length direction of the auxiliary part head portion are clamped in the first fixing groove and the second fixing groove respectively. In this way, after the pull tab auxiliary part is attached, the two first protruding portions are clamped in the first fixing groove and the second fixing groove respectively. Such a matching structure can reliably limit the random rotation and separation of the auxiliary part head portion, thereby limiting the random rotation and separation of the pull tab auxiliary part and improving the attachment reliability of the pull tab auxiliary part.

Preferably, at least one first fixing buckle is fixed on the surface of the auxiliary part attachment portion of the pull tab main body, and the first fixing buckle protrudes from the auxiliary part attachment portion along a thickness direction of the pull tab main body, and is located on an outer peripheral side of the first fixing groove and/or the second fixing groove. When the length direction of the auxiliary part head portion is consistent with the length direction of the pull tab main body, the first fixing buckle abuts against an outer peripheral side of the auxiliary part head portion, thereby further improving the attachment reliability of the pull tab auxiliary part.

Preferably, the two first protruding portions at the both ends of the auxiliary part head portion are respectively an outer protruding portion and an inner protruding portion. A groove wall contour of the first fixing groove and an outer peripheral contour of the outer protruding portion match with each other and are both semicircular. A length of the inner protruding portion is greater than a length of the second fixing groove. The second fixing groove penetrates through an outer edge of the auxiliary part attachment portion along the length direction of the pull tab main body. When the length direction of the auxiliary part head portion is consistent with the length direction of the pull tab main body, the outer protruding portion is clamped in the first fixing groove, the inner protruding portion is clamped in the second fixing groove, and a part of the inner protruding portion extends outward from the pull tab main body. When the pull tab auxiliary part is disassembled, the semicircular first fixing groove and the outer protruding portion facilitate the outer protruding portion to be rotated and separated from the first fixing groove, which also facilitate the disassembly operation of the pull tab auxiliary part. At the same time, the second fixing groove with a through structure at both ends is easy to process.

Further, a second fixing buckle protruding along a thickness direction of the pull tab main body is fixed on the surface of the auxiliary part attachment portion of the pull tab main body. The second fixing buckle is provided with a pair of third fixing grooves formed on a surface of the auxiliary part attachment portion and located on both sides of the attachment hole along the length direction of the pull tab main body. When the pull tab auxiliary part whose auxiliary part head portion passes through the attachment hole is rotated until the length direction of the auxiliary part head portion is consistent with the length direction of the pull tab main body, the length direction of the auxiliary part head portion intersects with the length direction of the attachment hole, and the two first protruding portions at both ends in the length direction of the auxiliary part head portion are clamped in the pair of third fixing grooves respectively. In this way, the reliability and stability of attaching the pull tab auxiliary part to the pull tab main body are effectively improved through the clamping of the first protruding portions and the third fixing groove, and the pull tab auxiliary part is reliably prevented from being accidentally separated from the pull tab main body.

Preferably, each of the third fixing grooves has at least one first inclined groove wall extending in an inclined manner such that the farther away from the attachment hole, the closer to a central axis of the pull tab main body, and each of the first protruding portions has at least one inclined surface on an outer periphery thereof. When the first protruding portion is clamped in the corresponding third fixing groove, the inclined surface has an inclination direction consistent with an inclination direction of the first inclined groove wall and is in abutting fit with the first inclined groove wall, thereby limiting the first protruding portion from shaking in the width direction of the pull tab main body. Further, when the pull tab auxiliary part is detached from the pull tab main body, the inclined first inclined groove wall facilitates the first protruding portions to be rotated and separated from the third fixing groove, thereby facilitating the disassembly of the pull tab auxiliary part.

Further, an outer peripheral surface of an outer end of the auxiliary part head portion is provided with an attachment guide inclined surface extending in an inclined manner such that the farther away from the auxiliary part column portion, the closer to a central axis of the auxiliary part head portion. In this way, when the pull tab auxiliary part is attached, the inclined attachment guide inclined surface facilitates the pressing of the auxiliary part head portion through the attachment hole, which makes the attachment operation of the pull tab auxiliary part more convenient.

Further, the pull tab main body is a metal part of an integrated structure, and thus the pull tab main body has good structural strength and is durable. At the same time, the pull tab auxiliary part is a plastic part of an integrated structure, which is convenient to manufacture and has low cost, and pull tab auxiliary parts with different shapes and colors can be easily designed at low cost. Combined with the detachable structure of the pull tab auxiliary part on the pull tab main body, a user can conveniently replace different pull tab auxiliary parts, and the design sense of slide fasteners is enriched.

The present invention further provides a slide fastener slider including a slider main body and the slide fastener pull tab described above, and the pull tab main body is connected to the slider main body.

As described above, the slide fastener pull tab with a pull tab auxiliary part rotatably assembled and disassembled and the slide fastener slider of the present invention have the following beneficial effects.

In the present application, neither the attachment hole nor the auxiliary part head portion is set to a perfect circle shape, and the contours of the attachment hole and the auxiliary part head portion match with each other. In this way, when the length direction of the auxiliary part head portion is consistent with the length direction of the attachment hole, the auxiliary part head portion can be easily and conveniently pressed into the attachment hole, and thus the auxiliary part head portion easily passes through the attachment hole. Then, the pull tab auxiliary part is rotated by an angle. The auxiliary part head portion abuts against the auxiliary part attachment portion to limit the separation of the auxiliary part head portion from the attachment hole, and thus the pull tab auxiliary part is reliably connected to the pull tab main body. Therefore, in the present application, the operation of pressing the auxiliary part head portion into the attachment hole is extremely easy, which not only facilitates the attachment and replacement of the pull tab auxiliary part, but also does not cause any constraints on the auxiliary part main body by the attachment hole, and does not limit the appearance design of the pull tab auxiliary part. This enables the present application to use the pull tab auxiliary part with any appearance, greatly improving and enriching the design of the slide fastener pull tab, and ultimately improving and enriching the design sense of slide fasteners.

As described above, the present invention effectively overcomes various disadvantages in the related art and has high industrial utilization value.

The embodiments described above are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Those skilled in the art can modify or change the embodiments described above without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
