FIELD OF THE INVENTION
The present invention relates to the structure of hair clips, particularly to an automatic pop-open hair clip.
BACKGROUND OF THE INVENTION
Traditional hair clips consist of a left clip body, a right clip body, a shaft seat, and a torsion spring. The torsion spring tightly binds the left and right clip bodies together. To use, one must press the non-clamping end of the left and right clip bodies with two fingers, allowing them to open and clamp the hair. To remove the hair clip from the hair, one must press again on the non-clamping end to separate the left and right clip bodies, thereby allowing the removal of the hair clip from the hair.
Although the operation is simple, it requires considerable effort, as a significant amount of pressing force is needed to open the left and right clip bodies. Additionally, the degree of clamping cannot be adjusted, which can easily damage the hair.
In light of this, providing a hair clip that resolves the aforementioned issues has become the objective of the development of this invention.

DETAILED DESCRIPTION OF THE EMBODIMENTS
Referring to FIGS. 1 to 8, an automatic pop-open hair clip 100 is provided, comprising a first clip body 1, a second clip body 2, and a helical clutch shaft 3. The first clip body 1 and the second clip body 2 are arranged to correspond with each other and can rotate relative to each other to jointly clamp an object. The helical clutch shaft 3 is pivotally set between the first clip body 1 and the second clip body 2, capable of providing the spring force necessary for the automatic pop-opening of the first clip body 1 and the second clip body 2. The helical clutch shaft 3 includes a first shaft body 31, a second shaft body 32, a cap 33, a resilient telescopic torsion element 34, and a shaft 35. One side of the first shaft body 31 is connected to the first clip body 1 and is sequentially provided with a first stop piece 311, a first helical rack 312, a guide part 313, with a first wing part 314 at the connection to the first clip body 1. One side of the second shaft body 32 is connected to the second clip body 2 and is sequentially provided with a second stop piece 321, a spacer part 322, a second helical rack 323, a sleeve 324, with a second wing part 325 at the connection to the second clip body 2. The second stop piece 321 is located outside the first stop piece 311 and serves as a restriction for the first stop piece 311. The spacer part 322 can accommodate the first stop piece 311 and the first helical rack 312, allowing both to move along the axis within it. The first tooth part 3121 of the first helical rack 312 is positioned on the side of the first shaft body 31 away from the first wing part 314. The second tooth part 3231 of the second helical rack 323 is positioned on the side of the second shaft body 32 away from the second wing part 325. The first tooth part 3121 and the second tooth part 3231 are correspondingly positioned and can engage with each other. The cap 33 is positioned at the free end of the guide part 313, corresponding to the sleeve 324 and can fit over it, with one side corresponding to the free end of the first wing part 314, provided with a third wing part 331 that can be positioned on the first wing part 314. The resilient telescopic torsion element 34 is positioned between the sleeve 324 and the cap 33, with both ends respectively pressing against the sleeve 324 and the cap 33, to utilize the spring force to provide the meshing force between the first helical rack 312 and the second helical rack 323, enabling the helical clutch shaft 3 to disengage during pressing. The shaft 35 passes through the first stop piece 311, the second stop piece 321, crosses over the spacer part 322, the second helical rack 323, and is positioned at the top end of the sleeve 324.
The first clip body 1 and the second clip body 2 are clamping structures, as shown in FIG. 1, primarily designed to secure hair. They can be made from various hard or elastic materials such as plastic, rubber, wood, ceramics, metal, etc. This allows for an expansion in the application range of the invention. For instance, when made from durable and shape-retaining materials like metal, ceramics, or wood, the durability and form variability of the invention are enhanced. When made from elastic materials like plastic or rubber, it can effectively protect the hair.
Furthermore, the first helical rack 312 and the second helical rack 323 move in a stepwise, forward direction, in conjunction with the spring force of the resilient telescopic torsion element 34, making the clamping process of the invention very smooth and easy to operate without jamming. As shown in FIGS. 5 and 6, when the user releases the clamp, the reaction force or spring force generated by the clamped object will push open the first clip body 1 and the second clip body 2. The stepwise structure of the helical clutch shaft 3, when subjected to the pushing force of reverse movement, will generate a very strong resistance to reverse movement. This resistance comes from the structural characteristics of the first helical rack 312 and the second helical rack 323 and the spring force of the resilient telescopic torsion element 34, preventing the helical clutch shaft 3 from disengaging and popping open. The tighter the clamping, the more engagement points there are, and the greater the resistance to reverse movement, thus providing the helical clutch shaft 3 with optimal engagement force and anti-disengagement effectiveness.
Moreover, the resilient telescopic torsion element 34 is enclosed within the sleeve 324 and the cap 33, isolated from external factors (such as hair, water, hair gel, and other contaminants), achieving an aesthetic and protective effect.
Additionally, although not shown in the FIGS., the first clip body 1 and the second clip body 2 can have decorative structures placed at any position on their outer surfaces, such as rhinestones, reliefs, or prints.
As illustrated in FIGS. 5 and 6, when using this invention, one simply needs to press on the sides of the first clip body 1 and the second clip body 2 to gradually rotate and clamp. Users can control the degree of pressure and clamping as per their requirements. At this time, referring to part of FIG. 3, although not shown in FIGS. 5 and 6, the torsion sections 341 at both ends of the resilient telescopic torsion element 34 will be compressed. The rebound force from the middle part of the resilient telescopic torsion element 34 will automatically apply pressure to the helical clutch shaft 3. The first helical rack 312 and the second helical rack 323 can engage and position each other, preventing them from being forced open by the reverse spring force of the torsion sections 341 at both ends of the resilient telescopic torsion element 34 and the reverse force applied by the clamped object, thus completing the clamping operation.
As shown in FIGS. 7 and 8, when the user wishes to remove the invention, they only need to press the first pressing piece 12 and the second pressing piece 22. This action causes the first helical rack 312 and the second helical rack 323 to separate (disengage). At this time, referring to FIG. 3, although not shown in FIGS. 7 and 8, the middle part of the resilient telescopic torsion element 34 will be compressed. The reverse spring force of the torsion sections 341 at both ends of the resilient telescopic torsion element 34 will automatically cause the helical clutch shaft 3 to pop open, driving the first clip body 1 and the second clip body 2 to complete the opening operation.
As seen in FIG. 3, the inner bottom surface of the sleeve 324 corresponding to the resilient telescopic torsion element 34 is provided with a first coupling groove 3241 for positioning and connecting the corresponding end of the resilient telescopic torsion element 34. Similarly, the inner bottom surface of the sleeve 324 corresponding to the resilient telescopic torsion element 34 is provided with a second coupling groove 332 for positioning and connecting the corresponding end of the resilient telescopic torsion element 34. Accordingly, the application of the first coupling groove 3241 and the second coupling groove 332 allows for a stable connection of the resilient telescopic torsion element 34, enabling it to expand, twist, and act smoothly.
As illustrated in FIGS. 1 and 2, the connection between the first clip body 1 and the first shaft body 31 is equipped with a first slot 11 for engaging and positioning with the first wing part 314. The first clip body 1 at the location corresponding to the second stop piece 321 is further equipped with a first pressing piece 12. The connection between the second clip body 2 and the second shaft body 32 is equipped with a second slot 21 for engaging and positioning with the second wing part 325. The second clip body 2 at the location corresponding to the cap 33 is further equipped with a second pressing piece 22. Hence, through the modular design of the first slot 11 and the second slot 21, the assembly of the first clip body 1, the second clip body 2, and the helical clutch shaft 3 is facilitated. Additionally, the setup of the first pressing piece 12 and the second pressing piece 22 not only facilitates pressing but also plays a role in limiting the position of the helical clutch shaft 3.
As seen in FIGS. 1 and 2, at the ends of the first slot 11 distant from the first shaft body 31, a first positioning block 13 is provided for engaging and positioning the first wing part 314. Similarly, at the ends of the second slot 21 distant from the second shaft body 32, a second positioning block 23 is provided for engaging and positioning the second wing part 325.
Accordingly, through the cooperation of the first positioning block 13 and the second positioning block 23, effective positioning of the corresponding first wing part 314 and the second wing part 325 is achieved. Combined with adhesive, a rapid and stable assembly of the first clip body 1, the second clip body 2, and the helical clutch shaft 3 can be accomplished.
Referring to FIG. 3, the resilient telescopic torsion element 34 is connected at its positioning points with the first coupling groove 3241 and the second coupling groove 333, and is additionally provided with a torsion section 341. The torsion section 341 can rotate synchronously with the corresponding first coupling groove 3241 and the second coupling groove 332. Thus, through the torsion section 341, the resilient telescopic torsion element 34 can smoothly expand, twist, and provide spring force for the helical clutch shaft 3, realizing the engagement and disengagement functions while preventing disengagement.
As shown in FIGS. 3 and 4, the engagement between the first wing part 314 and the third wing part 331 is recessed with a first engagement section 315, while the third wing part 331 corresponding to the first engagement section 315 is provided with a second engagement section 333 that can positionally engage with the first engagement section 315. Accordingly, this configuration ensures a stable and easy assembly between the first wing part 314 and the third wing part 331.
As illustrated in FIG. 3, the side of the first engagement section 315 corresponding to the second engagement section 333 is provided with at least one positioning hole 316; and the second engagement section 333 corresponding to the positioning hole 316 is equipped with a positioning peg 334 that can engage into the positioning hole 316. Hence, this setup ensures a foolproof and rapid positional engagement between the first engagement section 315 and the second engagement section 333.
The above descriptions serve as examples of implementations and are not intended to limit the scope of the rights of this case. Any modifications and variations that do not depart from the spirit and scope of this case should still fall within the scope of the patent for this invention.
