TECHNICAL FIELD

This utility model relates to the field of item storage technology, in particular to a locking buckle structure and a drawer box with the locking buckle structure.

BACKGROUND INFORMATION

Most of the existing conventional drawer boxes on the market are individually locked for a single drawer, and when unlocked, they are also individually unlocked for the drawer to be used. However, as professional users bring more and more tools, different tools need to be placed in different drawers for easy use and classification. Therefore, the method of locking and unlocking a single drawer separately is not suitable for practical use scenarios, because as the number of drawers increases, it is very inconvenient to lock and unlock a drawer separately. For example, if there are four drawers and different drawers need to be opened and closed from time to time during work, locking the drawers separately requires repeated unlocking to achieve the function of extracting the required drawers.

In view of this, it is necessary to design a lock structure that reduces user operation steps and a drawer box with this lock structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended purpose, the specific implementation methods, structures, features, and effects of the locking buckle structure and drawer box proposed based on the present utility model are described in detail below, combined with the accompanying drawings and implementation examples.

The aforementioned and other technical content, features, and functions of this utility model will be clearly presented in the detailed description of the implementation examples in conjunction with the reference diagram below. Through the explanation of specific implementation methods, a deeper and more specific understanding of the technical means and effects adopted by the present utility model to achieve the intended purpose can be obtained. However, the attached drawings are only for reference and explanation, and are not intended to limit the present utility model.

Example 1

Please refer to FIGS. 1 to 4 together. The present embodiment of the utility model provides a locking buckle structure 1001, which is mainly used in drawer box 1002, reducing user operation steps and having a simple structure. The locking buckle structure 1001 includes a push lock body 1010, multiple first elastic members 1011 set on the push lock body 1010, and multiple locking tongues 1012. The multiple first elastic members 1011 are located between the push lock body 1010 and the multiple locking tongues 1012, and each locking tongue 1012 is set on the push lock body 1010 through a first elastic member 1011. The first elastic member 1011 is used to automatically eject the locking tongue 1012 relative to the push lock body 1010, thereby keeping the locking buckle structure 1001 in a locked state.

Drawer box 1002 includes a drawer box body 1025 and multiple independent drawers 1020 arranged within the drawer box body 1025. Specifically, multiple drawers 1020 are arranged vertically within the drawer box body 1025, which has an opening, and each drawer 1020 can be pulled out from the opening of the drawer box body 1025.

Locking buckle structure 1001 has a locking/unlocking position, and drawer 1020 moves between a closed position and an open position through a closing direction and pulling direction. When the locking buckle structure 1001 is in the locked position, the drawer 1020 in the closed position is locked with the corresponding locking tongue 1012. The drawer 1020 in the pulled out or open position can be moved to the closed position and locked with the corresponding locking tongue 1012; When the locking buckle structure 1001 is in the unlocked position, the drawers 1020 located in the closed or pulled out position are all unlocked with the corresponding locking tongue 1012. At this time, all drawers 1020 can freely move between the closed and through the pulled out to the fully open positions. The drawer box 1002 of this utility model utilizes a locking buckle structure 1001 to simultaneously lock/unlock multiple drawers 1020, reducing user operation steps; Meanwhile, when the locking buckle structure 1001 is in the locked position, the drawer 1020 located in the pull-out position can be individually closed and automatically locked by the locking buckle structure 1001, further reducing the user's operational steps.

As shown in FIGS. 5 and 7, each drawer 1020 is equipped with a locking block 1022 corresponding to the locking tongue 1012. The locking block 1022 is matched with the locking tongue 1012 to prevent the drawer 1020 from pulling out from the opening, thereby locking the drawer 1020. When the locking buckle structure 1001 is in the locked position, the locking block 1022 of the drawer 1020 in the pulled out position can move over the corresponding locking tongue 1012 to the closed position to lock. At this time, the locking block 1022 is located on the side of the locking tongue 1012 away from the opening of the drawer box 1002; During this process, the locking tongue 1012 is located on the movement path of the locking block 1022. When the locking buckle structure 1001 is in the unlocked position, the locking block 1022 of the drawer 1020 in the pulled out position cannot be locked by crossing the locking tongue 1012; During this process, the locking tongue 1012 is not located on the movement path of the locking block 1022. It should be noted that when the locking tongue 1012 is located on the movement path of the locking block 1022, the locking tongue 1012 is horizontally aligned with the locking block 1022 before and after, and when the drawer 1020 moves from the pull-out position to the closed position, the locking block 1022 can cross the locking tongue 1012; When the locking tongue 1012 is not on the movement path of the locking block 1022, the locking tongue 1012 is located above the locking block 1022. In other embodiments, when the locking tongue 1012 is not on the movement path of the locking block 1022, the locking tongue 1012 can be located below the locking block 1022, and the locking tongue 1012 can also be located in the horizontal direction before and after the locking block 1022, and the locking block 1022 can never cross the locking tongue 1012.

Furthermore, each locking block 1022 forms a locking groove 1021 around the drawer body 1023, which is located on the side of the locking block 1022 near the opening. When the locking buckle structure 1001 is in the locked position and drawer 1020 is in the closed position, the locking tongue 1012 is stuck in the locking groove 1021 of the corresponding drawer 1020, thereby avoiding the shaking of drawer 1020 when locked; As shown in FIG. 6, when the locking buckle structure 1001 is in the unlocked position, each locking tongue 1012 detaches from the locking groove 1021.

The push lock body 1010 to move back and forth under force to switch the locking position and unlocking position of the locking buckle structure 1001. In this embodiment, the push lock body 1010 moves up and down, and moving up the push lock body 1010 can move the locking buckle structure 1001 to the unlocked position. The locking tongue 1012 is located above the locking block 1022 and not on the movement path of the locking block 1022; Pushing down the push lock body 1010 can move the locking buckle structure 1001 to the locking position, and the locking tongue 1012 is located on the movement path of the locking block 1022. The locking block 1022 can cross the locking tongue 1012 to lock.

Furthermore, as shown in FIGS. 5 and 7, a first oblique section 1012a is provided on the locking tongue 1012, and a support portion 1020a is provided on the drawer 1020 or drawer box body 1025. When the support portion 1020a is in contact with the first oblique section 1012a, the locking buckle structure 1001 remains in the locked or unlocked position, so that the locking buckle structure 1001 will not shift due to external forces. In this embodiment, the locking buckle structure 1001 moves up and down, and the first oblique section 1012a is set on the upper side of the locking tongue 1012. When the locking buckle structure 1001 moves up to the unlocked position, the first oblique section 1012a is in contact with the support portion 1020a, thereby keeping the locking buckle structure 1001 in the unlocked position. In other embodiments, the first oblique section 1012a can also be set on the lower side of the locking tongue 1012 and one side away from the opening, with the direction set on the locking tongue 1012 being the same as the unlocking/locking direction of the locking buckle structure 1001.

The push lock body 1010 is equipped with a locking tongue accommodating groove 1101. The first elastic member 1011 is a spring, and one end of the first elastic member 1011 (spring) is fixed in the locking tongue accommodating groove 1101. The locking tongue 1012 is fixed at the other end of the first elastic member 1011 (spring). When the first elastic member 1011 (spring) is compressed by force, the locking tongue 1012 can partially or completely retract into the locking tongue accommodating groove 101, so that the locking block 1022 can cross the locking tongue 1012 and lock. In this embodiment, when the locking buckle structure 1001 moves to the unlocked position, the locking tongue 1012 is squeezed by the drawer 1020 and remains in a partially retracted state within the locking tongue accommodating groove 1101 (as shown in FIG. 6). In this way, because the locking tongue 1012 and the first elastic members 1011 are separately assembled components, a push lock body 1010 can reserve multiple assembly positions for the locking tongue 1012, allowing for the design of unlocking and locking multiple drawers 1020 at will, without the need for different numbers of drawers 1020 to be matched with multiple push lock bodies 1010, saving costs.

In other embodiments, the first elastic member 1011 of the push lock body 1010 is a spring, one end of the first elastic member 1011 (spring) is fixed on the push lock body 1010, and the locking tongue 1012 is fixed on the other end of the first elastic member 1011 (spring). When the first elastic member 1011 (spring) is bent, the locking tongue 1012 can partially or completely retract into the locking tongue accommodating groove 1101.

Please refer to FIGS. 5 to 7 again. In this embodiment, when the push lock body 1010 is moved upwards, the locking tongue 1012 is compressed and compressed back into the locking tongue accommodating groove 1101 by the support portion 1020a, and the locking buckle structure 1001 is moved to the unlocked position. The locking tongue 1012 is compressed and continuously retracted back into the locking tongue accommodating groove 1101 by the support portion 1020a to maintain the unlocked position unchanged; When the push lock body 1010 is moved downwards, the locking tongue 1012 is squeezed out of the support portion 1020a and moved into the corresponding locking groove 1021, and the locking tongue 1012 is engaged in the locking groove 1021 under the action of the first elastic member 1011.

Please refer to FIGS. 8 to 10. On one side of the locking tongue 1012 near the opening, there is also a second oblique section 1012b. The direction of the second oblique section 1012b set on the locking tongue 1012 is opposite to the locking direction of the drawer 1020, so that it interferes with the locking direction of the drawer 1020. The locking block 1022 of drawer 1020 is equipped with a pushing part 1020b. When the locking buckle structure 1001 is in the locked position, the pushing part 1020b pushes the second oblique section 1012b to retract the locking tongue 1012 relative to the push lock body 1010 during the process of moving drawer 1020 from the pulled out position to the closed position. The pushing part 1020b of drawer 1020 located in the pulled out position can push the second oblique section 1012b to move over the locking tongue 1012 and lock it in the closed position. In this embodiment, when the drawer 1020 is moved to the closed position, the locking tongue 1012 corresponds to the position of the locking groove 1021, and the locking tongue 1012 extends into the locking groove 1021 under the action of the first elastic member 1011 (as shown in FIG. 10).

Furthermore, on the same side of the locking tongue 1012 as the second oblique section 1012b, there is a first straight surface 1012c, and on the opposite side of the second oblique section 1012b, there is a second straight surface 1012d. The first straight surface 1012c is opposite to the second straight surface 1012d; When the locking buckle structure 1001 is in the locked position, the locking block 1022 of the drawer 1020 in the closed position pushes the second straight surface 1012d towards the opening direction and moves towards the opening direction. At this time, the first straight surface 1012c interferes with the push lock body 1010 and cannot be moved. The locking tongue 1012 remains ejected, and the drawer 1020 cannot be opened.

The push lock body 1010 is equipped with a hand picking position 1102, which is used for fingers to insert and move the locking buckle structure 1001, thereby causing the locking buckle structure 1001 to move between the locking position and the unlocking position.

Please refer to FIGS. 2, 4, and 7 together. The locking buckle structure 1001 also includes a lock bolt 1014, which is fixed on the push lock body 1010. The drawer box 1002 is equipped with a buckle 1024 that matches the lock bolt 1014. Both the locking bolt 1014 and the buckle 1024 are equipped with locking holes. When the locking buckle structure 1001 moves to the locked position, the locking holes on the locking bolt 1014 and the buckle 1024 overlap. At this time, an external lock can be added to lock the locking bolt 1014 and the buckle 1024, thereby keeping the locking buckle structure 1001 in the locked position.

Furthermore, the locking buckle structure 1001 may also include a second elastic member (not shown), which automatically maintains the locking position of the locking buckle structure 1001. Specifically, the second elastic member is a spring, with its two ends fixed on the drawer box body and the push lock body respectively. When the locking buckle structure 1001 overcomes the elasticity of the second elastic member and moves to the unlocked position, any drawer 1020 can be moved to the pulled out position; When the force applied to the locking buckle structure 1001 is released, the push lock body 1010 automatically moves downwards under the rebound force of the second elastic member, causing the locking buckle structure 1001 to return to the locked position. It should be noted that since the second elastic member can automatically keep the locking buckle structure 1001 in the locked position, after setting the second spring, there is no need to set the first oblique section 1012a on the locking tongue 1012, and there is no need to set the support portion 1020a on the drawer 1020 or drawer box body 1025.

Example 2

Please refer to FIGS. 11 to 17 together. The present embodiment of the utility model provides a locking buckle structure 2001, which is mainly used in drawer box 2002, reducing user operation steps and having a simple structure. Among them, the locking buckle structure 2001 includes a push lock body 2010 and multiple locking tongues 2012 set on the push lock body 2010, which need to be moved simultaneously to lock/unlock. There are multiple independent drawers 2020 inside drawer box 2002 (only 2 are schematically shown in the figure), and each locking tongue 2012 corresponds to a drawer 2020 position. Locking buckle structure 2001 has a locking/unlocking position, and drawer 2020 has a closing/pulling position; When the locking buckle structure 2001 is in the locked position, the drawer 2020 in the closed position is locked with the corresponding locking tongue 2012. The drawer 2020 in the pulled out position can be moved to the closed position and locked with the corresponding locking tongue 2012; When the locking buckle structure 2001 is in the unlocked position, all drawers 2020 are unlocked with the corresponding locking tongue 2012. At this time, all drawers 2020 can be freely pulled out and closed.

Specifically, drawer box 2002 includes a drawer box body 2002a, with multiple drawers 2020 arranged vertically within the drawer box body 2002a. The drawer box body 2002a has an opening 2002b, and the drawer 2020 can be pulled out from the opening 2002b of the drawer box body 2002a.

Each drawer 2020 is equipped with a locking block 2022 corresponding to the locking tongue 2012. The locking block 2022 is matched with the locking tongue 2012 to prevent the drawer 2020 from being pulled out from the opening 2002b, thereby locking the drawer 2020. When the locking buckle structure 2001 is in the locked position, the locking block 2022 of the drawer 2020 in the pulled out position can move over the corresponding locking tongue 2012 to the closed position to lock. At this time, the locking block 2022 is located on the side of the locking tongue 2012 away from the opening 2002b of the drawer box 2002; During this process, the locking tongue 2012 is located on the movement path of the locking block 2022. When the locking buckle structure 2001 is in the unlocked position, the locking block 2022 of the drawer 2020 in the pulled out position cannot be locked by crossing the locking tongue 2012; During this process, the locking tongue 2012 is not located on the movement path of the locking block 2022. It should be noted that when the locking tongue 2012 is located on the movement path of the locking block 2022, the locking tongue 2012 is horizontally aligned with the locking block 2022 before and after, and when the drawer 2020 moves from the pull-out position to the closed position, the locking block 2022 can cross the locking tongue 2012; When the locking tongue 2012 is not on the movement path of the locking block 2022, the locking tongue 2012 is located above the locking block 2022. In other embodiments, when the locking tongue 2012 is not on the movement path of the locking block 2022, the locking tongue 2012 can be located below the locking block 2022, and the locking tongue 2012 can also be located in the horizontal direction before and after the locking block 2022, and the locking block 2022 can never cross the locking tongue 2012.

Each locking block 2022 forms a locking groove 2021 around the drawer body 2023, which is located on the side of the locking block 2022 near the opening 2002b. When the locking buckle structure 2001 is in the locked position and the drawer 2020 is in the closed position, the locking tongue 2012 is stuck in the corresponding locking groove 2021 (as shown in FIG. 12); When the locking buckle structure 2001 is in the locked position and drawer 2020 is in the pulled out position, moving drawer 2020 to the closed position can cause the locking block 2022 to cross the locking tongue 2012 to engage the locking tongue 2012 in the corresponding locking groove 2021, thereby locking drawer 2020.

Drawer 2020 has a drawer panel 2020a and two drawer side panels 2020b connected at both ends of the drawer panel 2020a, a drawer back panel (not indicated in the figure) set opposite to the drawer panel 2020a, and a drawer bottom plate connected to the drawer panel 2020a, drawer side panels 2020b, and the bottom of the drawer back panel (not indicated in the figure). When drawer 2020 is in the closed position, drawer panel 2020a is exposed from opening 2002b.

In this embodiment, the locking block 2022 is provided on one of the drawer side panels 2020b. Each locking block 2022 forms a locking groove 2021 around the drawer body 2023, which is located on the side of the locking block 2022 near the drawer panel 2020a (opening 2002b). When the locking buckle structure 2001 is in the locked position and drawer 2020 is in the closed position, the locking tongue 2012 is stuck in the locking groove 2021 of the corresponding drawer 2020, thereby avoiding the shaking of drawer 2020 when locked; As shown in FIG. 16, when the locking buckle structure 2001 is in the unlocked position, each locking tongue 2012 detaches from the locking groove 2021.

The drawer box 2002 of this utility model utilizes a locking buckle structure 2001 to simultaneously lock/unlock multiple drawers 2020, reducing user operation steps; Furthermore, when the locking buckle structure 2001 is in the locked position, the drawer 2020 located in the pull-out position can also be individually closed and automatically locked by the locking buckle structure 2001, further reducing the user's operational steps.

The push lock body 2010 to move back and forth under force to switch the locking position and unlocking position of the locking buckle structure 2001. In this embodiment, the push lock body 2010 moves up and down, and moving up the push lock body 2010 can move the locking buckle structure 2001 to the unlocked position. The locking tongue 2012 is located above the locking block 2022 and not on the movement path of the locking block 2022; Pushing down the push lock body 2010 can move the locking buckle structure 2001 to the locking position, and the locking tongue 2012 is located on the movement path of the locking block 2022. The locking block 2022 can cross the locking tongue 2012 to lock. It should be noted that during the process of locking when the locking block 2022 crosses the locking tongue 2012, the locking block 2022 pushes the corresponding locking tongue 2012 to move towards the unlocking position, and then the locking tongue 2012 drives all locking tongues 2012 (i.e. pushing the locking body 2010) to move towards the unlocking position. When the locking block 2022 crosses the locking tongue 2012, all locking tongues 2012 can move downwards together to lock in the locking position.

Furthermore, a first oblique section 2012a is provided on the oblique side of the locking tongue 2012 near the opening 2002b, and a pushing part 2022a is provided on the locking block 2022. When the locking buckle structure 2001 is in the locked position, the a pushing part 2022a of the drawer 2020 in the pulled out position pushes the first oblique section 2012a and moves the push lock body 2010 to move the locking block 2022 over the locking tongue 2012 to the closed position for locking.

The direction set on the locking tongue 2012 by the first oblique section 2012a not only makes it opposite to the closing direction of the drawer 2020, but also enables the linear movement of the pushing part 2022a to push the locking tongue 2012 in the vertical direction; In this embodiment, the first oblique section 2012a is located on the oblique side of the locking tongue 2012 near the opening 2002b, which roughly coincides with the edge at that position. When the locking buckle structure 2001 is in the locked position, during the process of moving drawer 2020 from the pulled out position to the closed position, the first oblique section 2012a is pushed against the pushing part 2022a, causing the locking tongue 2012 to move up and driving the push lock body 2010 to move up. The locking block 2022 passes over the locking tongue 2012, causing the locking tongue 2012 to correspond with the position of the locking groove 2021. The locking tongue 2012 falls into the locking groove 2021 and locks drawer 2020.

Furthermore, a second straight surface 2012d is provided on one side of the locking tongue 2012 away from the opening 2002b, and a third straight surface 2022b is provided on one side of the locking block 2022 near the opening 2002b; When the locking buckle structure 2001 is in the locked position, the locking block 2022 of the drawer 2020 in the closed position pushes the second straight surface 2012d of the locking tongue 2012 towards the direction of the opening 2002b, and the second straight surface 2002d interferes with the third straight surface 2022b to lock the drawer 2020.

Furthermore, the locking buckle structure 2001 further includes a second elastic member 2013, which automatically maintains the locking position of the locking buckle structure 2001. Specifically, the second elastic member 2013 is a spring, with its two ends fixed to the drawer box body 2002a and the push lock body 2010 respectively. When the locking buckle structure 2001 overcomes the elasticity of the second elastic member 2013 and moves up to the unlocked position, each drawer 2020 can move to the pulled out position. When the force applied to the locking buckle structure 2001 is released, the push lock body 2010 automatically moves down under the rebound force of the second elastic member 2013, causing the locking buckle structure 2001 to return to the locked position.

In this embodiment, the locking buckle structure 2001 further comprises multiple first elastic members 2011, one end of which is fixed on the push lock body 2010, the locking tongue 2012 is connected to the other end of the first elastic member 2011, and the first elastic member 2011 is, for example, a spring piece. The locking tongue 2012 protrudes outward from the surface of the push lock body 2010, and there is a locking tongue accommodating groove 2101 on the push lock body 2010. When the locking tongue 2012 is pushed by external force, the first elastic member 2011 (spring) bends inward, and the locking tongue 2012 can be pressed into the locking tongue accommodating groove 2101. In this design, when the locking buckle structure 2001 is equipped with a first elastic member 2011, the locking buckle structure 2001 can be directly pushed into the installation slot from the installation hole on the drawer box body 2002a for installation, and the installation method is relatively simple. On this basis, the locking tongue 2012 is equipped with a first straight surface 2012c on the same side as the first oblique section 2012a, and the first straight surface 2012c is opposite to the second straight surface 2012d; When the locking buckle structure 2001 is in the locked position, the locking block 2022 of the drawer 2020 in the closed position pushes the second straight surface 2012d towards the opening direction of the drawer panel 2020a (opening 2002b). At this time, the first straight surface 2012c interferes with the push lock body 2010, causing the locking tongue 2012 to not move towards the locking tongue accommodating slot 2101, thereby locking the drawer 2020 and preventing it from being opened.

Furthermore, on one side of the locking tongue 2012 facing the installation direction of the locking buckle structure 2001, there is a second oblique section 2012b. When installing the locking buckle structure 2001, the locking tongue 2012 is pressed into the locking tongue accommodating groove 2101 by pressing against the drawer box body 2002a through the second oblique section 2012b. After the locking buckle structure 2001 is installed in place, the locking tongue 2012 automatically pops out. In this embodiment, the locking buckle structure 2001 is installed into the installation hole from bottom to top, and the second oblique section 2012b is set on the upper surface of the locking tongue 2012.

In other embodiments, the locking tongue 2012 can also be directly fixed on the push lock body 2010 and protrudes outward from the surface of the push lock body 2010. For example, the locking tongue 2012 can be integrally formed with the push lock body 2010. It should be noted that when the locking tongue 2012 is fixed, there is no need to install a first elastic member 2011, a second oblique section 2012b, and a first straight surface 2012c on the locking tongue 2012.

Furthermore, the push lock body 2010 is equipped with a hand picking position 2102, which is used for fingers to insert and move the locking buckle structure 2001, thereby causing the locking buckle structure 2001 to move between the locked and unlocked positions.
