[0010] Preferably, the support component has a hollowed-out center, and the elastic snap-fit ​​component is connected to the support component on one side near the first connector, while the other side is suspended in the hollowed-out portion of the support component.

[0011] Preferably, one side surface of the elastic snap-fit ​​component is an inclined surface, and the elastic snap-fit ​​component can undergo elastic deformation when inserted into the cavity, and reset when the elastic snap-fit ​​component moves to the position corresponding to the snap-fit ​​hole.

[0012] Preferably, the elastic snap-fit ​​component has a limiting snap-fit ​​part on the side away from the first connector, and the limiting snap-fit ​​part can snap into the inner wall of the snap-fit ​​hole.

[0013] Preferably, there is a step between the limiting latching portion and the elastic latching component, and the height of the step is less than the maximum deformation height of the end of the elastic latching component away from the first connector.

Detailed Implementation

[0032] The core of this invention is to provide a snap fastener that is easy to use, can be opened and closed in pairs, and has low manufacturing cost.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In this embodiment, the buckle includes a first connector 2 and a second connector 10. The first connector 2 and the second connector 10 can be combined and separated to connect components such as fabric. It can be applied to backpacks, camera bags, mobile phone bags, various work clothes, motorcycle gear, clothing and other fields.

[0036] Specifically, the second connector 10 is provided with an elastic snap-fit ​​component 7, and the first connector 2 has a cavity inside for the elastic snap-fit ​​component 7 to enter. The side of the first connector 2 is provided with a snap-fit ​​hole 1 that can snap with the elastic snap-fit ​​component 7. That is, the first connector 2 is a female snap and the second connector 10 is a male snap. Specifically, the elastic snap-fit ​​component 7 undergoes elastic deformation when it enters the cavity. When it returns to its original position, it corresponds to the position of the snap-fit ​​hole 1. The end of the elastic snap-fit ​​component 7 away from the first connector 2 snaps with the inner wall of the snap-fit ​​hole 1 to achieve snap-fit. When it is necessary to separate the first connector 2 and the second connector 10, the elastic snap-fit ​​component 7 is pressed. After the elastic snap-fit ​​component 7 separates from the snap-fit ​​hole 1, the first connector 2 and the second connector 10 can be separated.

[0037] Furthermore, the second connector 10 is also provided with a support member 6, and an elastic snap-fit ​​member 7 is located on the support member 6. The first connector 2 is provided with limiting grooves 5 on both sides of the end near the second connector 10. Specifically, the extension length of the limiting groove 5 is less than the length of the support member 6 in the insertion direction. The two sides of the end of the support member 6 away from the first connector 2 can be inserted into the limiting groove 5. The two sides of the support member 6 are also provided with limiting members 8. The limiting members 8 can be baffles. The distance between the two baffles on both sides of the support member 6 should match the width between the two limiting grooves 5 of the first connector 2. The limiting members 8 can also be used as the operating force point for the operator. After the first connector 2 and the second connector 10 are combined, the limiting members 8 are located outside the limiting grooves 5.

[0038] The buckle provided by the present invention, by setting a limiting groove 5 on the first connecting member 2 and setting a supporting member 6 and a limiting member 8 on the second connecting member 10, can ensure the positional stability between the supporting member 6 and the first connecting member 2 by utilizing the cooperation between the limiting member 8 and the limiting groove 5. At the same time, by utilizing the height difference formed between the limiting member 8 and the outer surface of the limiting groove 5 of the first connecting member 2, the limiting member 8 can prevent the fabric from entering the limiting groove 5 during assembly, effectively avoiding the fabric being clamped and ensuring the reliability of use.

[0039] Based on the above embodiments, the width of the support member 6 at the end closest to the first connector 2 is smaller than the width of the other end. Specifically, the support member 6 includes at least two support columns, with a connecting plate on the side of the two support columns closest to the first connector 2. An elastic locking member 7 is provided on the side of the connecting plate furthest from the first connector 2, and a second locking part 13 is located on the side of the connecting plate closest to the first connector 2. The two support columns are symmetrically arranged and both are bent, ensuring that the width of the support member 6 at the end closest to the first connector 2 is smaller than the width of the other end. With this arrangement, during assembly, the smaller front end width of the support member 6 makes it easier to insert into the cavity and facilitates fastening; combined with the limiting groove 5 and the limiting member 8, the reliability of the connection between the first connector 2 and the second connector 10 can be guaranteed.

[0040] Based on the above embodiments, a first engaging portion 4 is provided on the side of the cavity of the first connecting member 2 away from the second connecting member 10, and a second engaging portion 13 is provided on the end of the supporting member 6 near the first connecting member 2. The first engaging portion 4 and the second engaging portion 13 can be engaged in the left-right direction along the first connecting member 2 or the second connecting member 10. Preferably, the first engaging portion 4 is a locking platform, and the second engaging portion 13 is a locking groove.

[0041] Based on the above embodiments, the middle part of the support member 6 is hollowed out, the side of the elastic snap-fit ​​member 7 near the first connector 2 is connected to the support member 6, and the other side is suspended in the hollowed-out part of the support member 6. The hollowed-out part can facilitate the deformation of the elastic snap-fit ​​member 7.

[0042] Furthermore, one surface of the elastic locking component 7 is inclined. When inserted into the cavity, the elastic locking component 7 can undergo elastic deformation. That is, the inclined surface, under the action of the inner wall of the cavity of the first connecting member 2, pushes the elastic locking component 7 to swing until it moves to a position corresponding to the locking hole 1, at which point it resets, thus achieving locking. Specifically, this can be achieved by increasing the thickness of the elastic locking component 7 from one end closer to the first connecting member 2 towards the other end, as in the scheme of this application. Figure 7 It can be seen that, of course, this can also be achieved by changing the extension angle of the elastic snap-fit ​​component 7.

[0043] Based on the above embodiments, the elastic snap-fit ​​component 7 is provided with a limiting snap-fit ​​part 9 on the side away from the first connector 2, and the limiting snap-fit ​​part 9 can snap into the inner wall of the snap-fit ​​hole 1.

[0044] Specifically, there is a step between the limiting latching part 9 and the elastic latching part 7, and the height of the step is less than the maximum deformation height of the end of the elastic latching part 7 away from the first connecting member 2. In the combined state, the limiting latching part 9 can effectively prevent the elastic deformation of the elastic latching part 7 from being too large, so as to prevent the pressing force from being too large and making it difficult to open.

[0045] Based on the above embodiments, both the first connector 2 and the second connector 10 are provided with connecting seats for connecting the fabric, thereby realizing the connection of the fabric. Of course, the fabric can also be replaced with other components that need to be connected.

[0046] Based on the above embodiments, the second connector 10 is provided with a gripping part 11 on the side away from the first connector 2, which makes it convenient for the user to pick it up.

[0047] Based on the above embodiments, the first connecting member 2 includes a cover 12, with a snap-fit ​​hole 1, a cavity, and a limiting groove 5 all located on the cover 12. The first snap-fit ​​part 4 connects to the two sides of the cover 12, and each side of the cover 12 is provided with a snap-fit ​​hole 1, so that both sides of the first connecting member 2 can be effectively fastened to the second connecting member 10. Furthermore, at least one side of the cover 12 is provided with a spring piece 3. The spring piece 3 can deform when the elastic snap-fit ​​part 7 snaps into the snap-fit ​​hole 1, and the spring piece 3 can separate the elastic snap-fit ​​part 7 from the snap-fit ​​hole 1 when pressed by an external force. With the above configuration, the spring piece 3 allows the first connecting member 2 and the second connecting member 10 to be separated by pressing the spring piece 3. Additionally, the spring piece 3 can also block the snap-fit ​​hole 1, preventing the fabric from being pinched and avoiding injury to the arm.

[0048] Preferably, the spring clip 3 is located on one side of the cover 12, and the spring clip 3 and the cover 12 are an integral structure. By setting the spring clip 3 on one side of the cover 12 and only retaining the snap-fit ​​hole 1 on the other side, the second connector 10 can cooperate with the first connector 2 on both sides, and the two sides adopt different opening and closing methods, which increases the user experience of the buckle and adds fun. Specifically, the A side and B side of the first connector 2 have different structures, such as... Figure 4-1 As shown, surface A has a snap-fit ​​hole 1, forming a hollow surface, which is the first type of opening and closing method. The opening and closing is completed by the worker directly pressing the elastic snap-fit ​​component 7; as shown... Figure 4-2 As shown, side B, spring 3, is the second type of opening and closing mechanism, which is completed by the workers directly pressing spring 3.

[0049] Method 1, such as Figure 5-7 As shown, when the A-side of the first connector 2 faces upward and is combined with the second connector 10: when the A-side locking hole 1 of the first connector 2 faces upward, by squeezing the gripping part 11 of the second connector 10 or pinching the limiting part 8 of the second connector 10 from the side, the second connector 10 is gently pushed into the cover 12 of the first connector 2. When the elastic locking part 7 touches the inner wall of the cover 12 of the first connector 2, the elastic locking part 7 is pressed down to be able to enter the cover 12 of the first connector 2. After entering the cover 12, the elastic locking part 7 reaches the A-side locking hole 1 of the first connector 2, as shown. Figure 6 As shown, the elastic snap-fit ​​component 7 returns to its initial state, springing back into the snap-fit ​​hole 1 on the A side of the first connector 2. Simultaneously, when the second snap-fit ​​portion 13 inside the cover 12 engages with the first snap-fit ​​portion 4, as... Figure 3 As shown, the fastening is complete;

[0050] When the first connector 2A is opened with its face facing upwards: As shown in Figure 4, it is in the locked state. When the worker presses the elastic locking component 7, the elastic locking component 7 descends into the cover 12 of the first connector 2, and the second connector 10 pops out, thus completing the opening.

[0051] Method 2, such as Figure 8-10 As shown, when the B-side of the first connector 2 is facing upwards and combined with the second connector 10: when the spring piece 3 on the B-side of the first connector 2 is facing upwards, by squeezing the gripping part 11 of the second connector 10 or pinching the limiting part 8 of the second connector 10 from the side, the second connector 10 is gently pushed into the cover 12 of the first connector 2. When the elastic locking part 7 touches the inner wall of the cover 12 of the first connector 2, the elastic locking part 7 is pressed down to be able to enter the cover 12 of the first connector 2. After entering the cover 12, the elastic locking part 7 reaches the spring piece 3, as shown. Figure 9 When the spring piece 3 returns to its initial state, the elastic locking component 7 springs back to a state of contact with the spring piece 3 on the surface of the first connector 2B. At the same time, when the first locking part 4 inside the cover 12 mates with the second locking part 13, as... Figure 3 As shown, the fastening is complete.

[0052] When the first connector 2B is opened with its side facing upwards: (as shown in the image) Figure 7 When the device is engaged, when the operator presses the spring piece 3 on the B side of the first connector 2, the spring piece 3 is pressed down, causing the tangential elastic locking component 7 to be pressed down and fall into the cover 12 of the first connector 2, so that the second connector 10 can be popped out and the device can be opened.

[0053] This buckle features a simple and elegant design, is easy to use, and opens and closes in pairs. It is easy to snap into place during assembly without the need for alignment, thus improving efficiency. The first connecting piece 2 has different opening and closing methods on both sides, enhancing the user experience and adding a touch of fun. The two sides of the first connecting piece 2 can also be treated with contrasting colors, improving the product's aesthetics and selectivity. A limiting component 8 is added to the side, creating a height difference with the female buckle, making it less likely to get stuck on clothing fabric. It has low processing costs and good market performance. It can be operated with one hand, making it convenient to use.
