Description

Technical Field

[0001] This utility model relates to the field of fasteners, specifically an elastic self-locking fastener. Background Technology

[0002] With the development of technology, buckles are frequently used in outdoor products such as bags, safety gear, and travel bags to facilitate the disassembly and connection of shoulder straps. Therefore, buckles need to be stable when fastened and easy to separate and open. Existing buckles (such as those shown in patent CN201920703472.1) require the male and female buckles to be moved horizontally to misalign the hooks before they can be separated vertically, which is cumbersome. Especially when the magnetic force is weak, the male and female buckles may experience relative displacement in the horizontal direction due to daily use, making the buckle prone to separation due to vertical forces, which greatly affects the stability of the buckle fastening. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an elastic self-locking fastener that allows users to easily open the fastener and improves the stability of the fastener when it is closed.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An elastic self-locking fastener includes an upper main component, a lower main component, and a slider; the lower main component and the upper main component are detachably inserted and fixed by a horizontal limiting mechanism; a self-locking spring is provided between the side wall of the slider and the side wall of the upper main component; the slider is horizontally slidably inserted into the upper main component; a hook and a lower inclined surface are formed on the lower main component, and an upper inclined surface is formed on the slider; the hook engages with the slider; a sliding cover is provided on the slider, the sliding cover and the slider are fixedly connected, and the sliding cover is slidably mounted on the upper main component.

[0006] Furthermore, the horizontal limiting mechanism includes a plurality of locking blocks and locking slots that match the locking blocks. The locking blocks are formed on the upper main component, the locking slots are formed on the lower main component, and the locking blocks are embedded in the locking slots.

[0007] Furthermore, one end of the self-locking spring is integrally formed on the side wall of the slider, and the other end of the self-locking spring abuts against the inner side wall of the upper main component.

[0008] Furthermore, a limiting groove is formed on the upper main component, and a limiting strip is formed on the sliding cover. The length of the limiting strip is less than the length of the limiting groove; the limiting strip can be slidably inserted into the limiting groove.

[0009] Furthermore, a fixing hook is formed on the sliding cover, a fixing groove is formed on the slider, a limiting platform is formed in the fixing groove, and the fixing hook is engaged with the limiting platform.

[0010] Furthermore, a sliding cavity is formed inside the upper main component, and a sliding groove is formed on the side wall of the sliding cavity; a sliding strip is formed on the side wall of the slider, the slider is slidably installed in the sliding cavity, and the sliding strip is inserted into the sliding groove.

[0011] Furthermore, a relief groove is formed on the slide bar. When the fastener is engaged, the hook passes through the relief groove and hooks onto the upper wall of the slide bar.

[0012] Furthermore, a top block is formed on the slider, and a top strip is formed on the upper main component, with the sidewalls of the top block and the sidewalls of the top strip abutting against each other.

[0013] Furthermore, a guide slope is formed on the top block.

[0014] Furthermore, the self-locking spring is made of metal, a spring seat is formed on the side of the slider, one end of the self-locking spring is mounted on the spring seat, and the other end of the self-locking spring abuts against the inner side wall of the upper main component.

[0015] By adopting the above-described technical solution of this utility model, at least the following beneficial effects are achieved:

[0016] 1. When the fastener is engaged, the self-locking spring is in a pre-tightened state, and the slider automatically engages and locks with the hook under the action of the pre-tightened spring. The locking block is embedded in the slot, thus restricting the relative horizontal displacement of the upper and lower main components. At this time, the hook engages with the slider, restricting the relative vertical displacement between the upper and lower main components, greatly improving the stability of the fastener during engagement. When the fastener needs to be disengaged, an external force is applied to slide the slider. At this time, the self-locking spring is compressed, causing the hook and the slider to disengage. Simultaneously, the upper and lower inclined surfaces abut and slide relative to each other, thus raising one side of the slider, which in turn raises one side of the upper main component. The locking block on one side of the fastener will gradually disengage from the slot. The torque generated by sliding the slider can directly pry the upper and lower main components apart. Therefore, when the fastener is disengaged, only a force in one direction needs to be applied to the slider to complete the disengagement, improving the convenience of fastener disengagement.

[0017] Second, the sliding engagement of the slide bar and the slide groove allows the slider to slide more smoothly within the slide cavity, greatly facilitating the fastening and disengagement of the fastener.

[0018] Third, the sliding cover and the slider are fixedly connected, and the length of the limiting strip is less than the length of the limiting groove, so that the range of motion of the slider is restricted to prevent the slider from falling out of the sliding cavity. The abutting connection between the top block and the top strip further limits the range of motion of the slider and improves the stability of the fastener.

[0019] Compared with the prior art, this utility model uses an elastic self-locking fastener. When the fastener is engaged, it can be automatically locked by the self-locking spring, and the horizontal and vertical movement between the upper main component and the lower main component is restricted, so that the fastener has good stability when engaged. When the fastener is disengaged, only an external force in one direction needs to be applied to complete the disengagement, which improves the convenience of fastener disengagement.

[0035] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Please see the appendix Figures 1 to 7 As shown, this utility model provides an elastic self-locking fastener, including an upper main component 1, a lower main component 2, and a slider 3; the lower main component 2 and the upper main component 1 are detachably inserted and fixed by a horizontal limiting mechanism 5; a self-locking spring 6 is provided between the side wall of the slider 3 and the side wall of the upper main component 1; the slider 3 can be horizontally slidably inserted into the upper main component 1; a hook 22 and a lower inclined surface 23 are formed on the lower main component 2, and an upper inclined surface 34 is formed on the slider 3; the hook 22 is engaged with the slider 3; the horizontal limiting mechanism 5 includes a plurality of locking blocks 11 and locking grooves 21 that match the locking blocks 11, the locking blocks 11 are formed on the upper main component 1, the locking grooves 21 are formed on the lower main component 2, and the locking blocks 11 are embedded in the locking grooves 21. When the fastener is engaged, the self-locking spring 6 is in a pre-tightened state, and the slider 3 automatically engages and locks with the hook 22 under the action of the self-locking spring 6. The locking block 11 is embedded in the locking groove 21, which can restrict the relative horizontal displacement of the upper main component 1 and the lower main component 2. At this time, the hook 22 is on the slider 3, which restricts the relative vertical displacement between the upper main component 1 and the lower main component 2, greatly improving the stability of the fastener when it is engaged. When the fastener needs to be separated, an external force is applied to slide the slider 3. At this time, the self-locking spring is compressed, causing the hook 22 and the slider 3 to disengage. Simultaneously, the upper inclined surface 34 and the lower inclined surface 23 abut and slide relative to each other, thus raising one side of the slider 3, which in turn raises one side of the upper main component 1. The locking block 11 on one side of the fastener will gradually disengage from the slot 21. The torque generated by sliding the slider 3 can directly pry the upper main component 1 and the lower main component 2 apart. Therefore, when the fastener is separated, only a force in one direction needs to be applied to the slider 3 to complete the separation, improving the convenience of fastener separation. In addition, the lower edge of the locking block 11 can be provided with an appropriate shape and size of bevel, and the locking block 11 and the slot 21 are provided with an appropriate gap, which further improves the smoothness of fastener separation.

[0037] Preferably, the slider 3 is provided with a sliding cover 4, the sliding cover 4 and the slider 3 are fixedly connected, and the sliding cover 4 is slidably mounted on the upper main component 1. Otherwise, as... Figure 4 As shown, a fixing hook 42 is formed on the sliding cover 4, and a fixing groove 33 is formed on the slider 3. A limiting platform 35 is formed within the fixing groove 33, and the fixing hook 42 is engaged with the limiting platform 35. Thus, when the user separates the fastener, they only need to push the sliding cover 4 to move the slider 3. In addition, a rope hole 39 for attaching a pull rope is formed on the slider 3, and a rope groove 17 is formed on the upper main component 1; the rope hole 39 and the rope groove 17 are connected, allowing the user to also pull the slider 3 to separate the fastener by pulling the rope, greatly facilitating the user's operation. Furthermore, the sliding cover 4 can prevent impurities from entering between the upper main component 1 and the slider 3, improving the stability of the fastener.

[0038] Preferably, such as Figure 3 and Figure 5 As shown, a sliding cavity 12 is formed inside the upper main component 1, and a sliding groove 13 is formed on the side wall of the sliding cavity 12; a sliding strip 31 is formed on the side wall of the slider 3, and the slider 3 is slidably installed in the sliding cavity 12, with the sliding strip 31 inserted into the sliding groove 13. Through the sliding engagement of the sliding strip 31 and the sliding groove 13, the slider 3 can slide more smoothly in the sliding cavity 12, greatly facilitating the fastening and disengagement of the fastener.

[0039] Preferably, a relief groove 32 is formed on the slide bar 31. When the fastener is engaged, the hook 22 passes through the relief groove 32 and hooks onto the upper wall of the slide bar 31. This restricts the vertical movement between the upper main component 1 and the lower main component 2.

[0040] Preferably, a limiting groove 14 is formed on the upper main component 1, and a limiting strip 41 is formed on the sliding cover 4. The length of the limiting strip 41 is less than the length of the limiting groove 14. The limiting strip 41 is slidably inserted into the limiting groove 14. The sliding cover 4 and the slider 3 are fixedly connected. A top block 36 is formed on the slider 3, and a top strip 16 is formed on the upper main component 1. The sidewalls of the top block 36 and the top strip 16 abut against each other. This restricts the range of motion of the slider 3, preventing it from falling out of the sliding cavity 12. The abutting connection between the top block 36 and the top strip 16 further limits the range of motion of the slider 3, improving the stability of the fastener. Preferably, a guide slope 37 is formed on the top block 36, which facilitates the embedding of the slider 3 into the sliding cavity 12.

[0041] Preferably, the upper main component 1 has an upper strap hole 15, and the lower main component 2 has a lower strap hole 24. The upper strap hole 15 and the lower strap hole 24 can be used to fix and install a shoulder strap or waist belt, etc.

[0042] Preferably, such as Figure 7 As shown, in another embodiment, the self-locking spring 6 is made of metal, and a spring seat 38 is formed on the side of the slider 31. One end of the self-locking spring 6 is mounted on the spring seat 38, and the other end of the self-locking spring 6 abuts against the inner sidewall of the upper main component 1. The self-locking spring 6 is pre-tightly mounted between the sidewall of the slider 3 and the sidewall of the upper main component 1, so that the slider 3 can be engaged by the hook 22 in the free state.

[0043] Compared with the prior art, this utility model uses an elastic self-locking buckle. When the buckle is engaged, it can be automatically locked by the self-locking spring 6, and the horizontal and vertical movement between the upper main component 1 and the lower main component 2 is restricted, so that the buckle has good stability when engaged. When the buckle is disengaged, only an external force in one direction needs to be applied to complete the separation of the buckle, which improves the convenience of buckle separation.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
