Description

Technical Field

[0001] The utility model relates to the field of buckle products, in particular to a buckle piece. Background Art

[0002] Snap fasteners are commonly used connectors in luggage, child safety seats, baby strollers, and clothing, facilitating bundling and playing a fixing role. They are convenient and safe to use. Safety snap fasteners can also be used in activities such as rock climbing, mountaineering, and bungee jumping to ensure people's life safety in specific environments. When traditional snap fasteners are used, during the long-term plugging and unplugging process of the male and female fasteners, due to the repeated insertion and extraction of the two pins, material wear and aging will occur, resulting in embrittlement or even fracture of the pin's deformation ability, and elastic deformation is more likely to occur. Therefore, when traditional snap fasteners are used in activities closely related to people's personal safety such as rock climbing, mountaineering, bungee jumping, and safety belts, serious safety hazards may be brought.

[0003] To solve the above existing problems, a snap fastener with the patent number 201910153316.7 discloses the following solution idea: "including a male fastener and a female fastener that cooperates with the male fastener. The male fastener includes a male fastener body and a plug integrally designed with the male fastener body. The female fastener includes a female fastener body, two elastic components, two hook heads rotatably arranged on the female fastener body, and two buckle arms rotatably arranged on the female fastener body. The plug is inserted between the two hook heads, one end of each of the two buckle arms is inserted into each of the two hook heads, one end of the elastic component abuts against the hook head, and the other end of the elastic component abuts against the female fastener body." It indeed solves the problem that when the male and female fasteners are engaged or disengaged, the male fastener does not need to deform, and it is not easy to break and embrittle. However, there are many components set in this snap fastener, and it is easy to encounter the situation where it cannot be used continuously after a single component breaks. Moreover, the large number of components will also increase the cost and selling price of the snap fastener, making it less competitive in the market.

[0004] To solve the above problems, the utility model proposes a buckle piece that is convenient for disassembly and separation and does not damage the webbing. Summary of the Utility Model

[0005] (I) Purpose of the Utility Model

[0006] In view of this, the purpose of the utility model is to provide a buckle piece to solve the technical problems existing in the prior art.

[0007] (II) Technical Solution

[0008] In order to achieve the above-mentioned technical purpose, the utility model provides a fastener, whose structure includes a first fastener and a second fastener that are engaged with each other, the second fastener is provided with a pressing portion for limiting the first fastener to be engaged therein after insertion, the pressing portion is provided with at least one, and the pressing portion is elastically and movably pressed on the edge of the first fastener through an elastic connecting element.

[0009] Preferably, the first fastener comprises a first fastener body, a first boss is provided above the first fastener body, and the first boss extends toward the mating direction to be provided with a protruding mating end.

[0010] Preferably, the second fastener comprises a second fastener body, and a second boss is provided above the second fastener body;

[0012] Preferably, a channel for inserting the first fastener is provided in the middle of the second fastener, and the pressing portion is arranged on the outward side of the second fastener. By arranging the pressing portion on the outside, it is convenient for manual operation during use.

[0013] Preferably, a locking mouth extending in the mating direction is provided at the bottom of the first fastener body, and the front and rear side edges of the locking mouth are provided with R-shaped chamfers that cooperate with the contact tip of the pressing portion. By performing a smooth transition treatment on the edge with the R-shaped chamfer, compared with the right-angle shape or other shapes of structures and the contact tip, the R-shaped chamfer can be smoother when opened and inserted, and better realize the engagement and separation, and prevent the occurrence of jamming.

[0014] Preferably, the pressing parts are provided with two and are symmetrically arranged on the front and rear sides of the second fastener. The stacked pressing parts can facilitate the user to better perform bidirectional symmetrical operations and quickly separate the first fastener and the second fastener.

[0015] Preferably, the pressing portion is hinged on the second fastener and is limited by a rivet, and a through hole for rivet installation is provided in the middle of the pressing portion;

[0016] The second fastener is provided with second rivet holes for installing rivets at the upper and lower ends, which is beneficial to ensure that the pressing part can effectively rotate in the second fastener.

[0017] Preferably, a limiting groove for arranging an elastic connecting element is provided inside the second fastener, which facilitates better limiting of the elastic connecting element; during assembly, the elastic connecting element obliquely abuts against the edge of the pressing portion, which can effectively make the pressing portion return to its original state after insertion, thereby realizing the clamping of the first fastener.

[0018] Preferably, at least one limiting post is riveted to the center of the second fastener, and the limiting post is arranged in the first riveting hole of the second fastener;

[0019] A plugging hole matched with the limiting post is provided on the first fastener, and the plugging hole is arranged in a U shape; during assembly, the plugging hole is fitted with the edge of the limiting post;

[0020] In this solution, at least one limiting post is riveted to the center of the second fastener, which increases the effect of positioning and clamping, makes it safer to use, and can avoid the phenomenon that it is not easy to accidentally open unilaterally when the deformation degrees of the elastic connecting elements on both sides are different. In the case where pressing portions are provided on both sides, after adding the limiting post, the first fastener and the second fastener can only be separated by pressing both sides simultaneously, and it can play a role in preventing unhooking, preventing shaking, and preventing slipping during use.

[0021] Preferably, at least one first rope-passing groove is provided on the first fastener, and at least one second rope-passing groove is provided on the second fastener, which facilitates the threading of the webbing when this structure is applied to application scenarios such as luggage and belts.

[0026] Specifically, in this solution, the first fastener can be limited after being inserted only through the cooperation of the elastic connecting element and the pressing portion. Compared with the prior art, which uses several cooperating parts, the number of parts used is reduced, the manufacturing cost is reduced, and the situation where the entire fastener cannot be used due to other parts is avoided, thereby extending the service life of the fastener. At the same time, due to the reduced production cost, the product price is also cheaper in comparison, with high cost performance and more competitive in the market.

[0027] At the same time, in the solution of the prior art, since the plug is inserted between the two hook heads, one end of the two buckle arms is respectively inserted in the two hook heads, one end of the elastic component is in contact with the hook heads, and the other end of the elastic component is in contact with the female buckle body. Therefore, the balance between the male buckle and the female buckle is mainly determined by the elastic components arranged on both sides. If the elastic forces of the elastic components on both sides are not equal during long-term use, that is, the deformation processes are not equal, one side may accidentally open during use, which poses a potential safety hazard. To address this phenomenon, the present solution further provides at least one limit column riveted in the center of the second fastener, and a plug-in hole cooperating with the limit column is provided on the first fastener. After the first fastener and the second fastener are assembled, the phenomenon of accidental opening of one side during use can be avoided, and it can play a multiple role of preventing unhooking, preventing shaking, and preventing slipping.
