Description

Technical Field

[0001] The utility model belongs to the field of clothing accessories, and particularly relates to a four-corner four-joint buckle with large buckle force, good stability, strong anti-destruction force and long service life. Background Art

[0002] Snap fasteners are widely used on clothing, and the requirements for snap fasteners are higher in wearable devices in harsh environments such as outdoor and mountaineering. At present, ordinary snap fasteners are generally used. The surface buckle on the female buckle and the bottom buckle on the male buckle have only one fastening rivet. This snap fastener with only a single rivet can meet certain usage requirements, but it also has major defects, such as small fastening force, poor stability, weak anti-destructive power, easy damage and failure, inconvenient use, and cannot effectively meet usage requirements.

[0003] The technical problem to be solved by the utility model is to provide a four-corner four-joint buckle which has large buckling force, good stability, strong anti-destructive force, is not easy to be damaged and invalidated, is easy to use and effectively meets the use requirements. Utility Model Content

[0004] In order to solve the problems of the single rivet in the prior art, such as small fastening force, poor stability, weak anti-destructive force, easy damage and failure, inconvenient use, and failure to effectively meet the use requirements, the utility model adopts the following technical solutions:

[0005] The utility model provides a four-corner snap fastener, comprising a face buckle, a female buckle, a male buckle and a bottom buckle, wherein four upper rivets are evenly distributed on the bottom end surface of the face buckle, the four upper rivets of the face buckle pass downward from the top of the female buckle and are stamped and riveted to form a whole, the bottom buckle is provided with a lower rivet, the lower rivet of the bottom buckle passes upward from the bottom of the male buckle and is stamped and riveted to form a whole, a hook edge is provided on the inner side of the bottom of the female buckle, an arc groove is provided on the outside of the male buckle, the hook edge and the arc groove are interference fit, and the female buckle is fastened and fixed by the interference fit of the hook edge and the arc groove of the male buckle.

[0006] Preferably, the female buckle is provided with four female buckle notches on the buckling surface, and the male buckle is provided with two male buckle notches on the buckling surface.

[0007] The beneficial effects of the utility model are: four rivets are arranged on the face buckle to fasten and fix it with the female buckle, the buckling force is large, the stability is good, the anti-destructive force is strong, it is not easy to be damaged and fail, it is easy to use, and the use requirements are effectively met.

[0012] The preferred embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0013] See also Figure 1 A four-corner snap fastener comprises a face buckle 1, a female buckle 2, a male buckle 3 and a bottom buckle 4, wherein four upper rivets 11 (such as Figure 2 As shown), the four upper rivets 11 of the face buckle 1 pass downward from the top of the female buckle 2 and are fixed by punching and riveting to form a whole. The bottom buckle 4 is provided with a lower rivet 41, and the lower rivet 41 of the bottom buckle 4 passes upward from the bottom of the male buckle 3 and is fixed by punching and riveting to form a whole. The inner side of the bottom of the female buckle 2 is provided with a hook edge 21, and the outer side of the male buckle 3 is provided with an arc groove 31. The hook edge 21 and the arc groove 31 are interference fit. The female buckle 2 is fastened and fixed by the interference fit of the hook edge 21 and the arc groove 31 of the male buckle 3. Since the four rivets on the face buckle are fastened and fixed with the female buckle, the fastening force is large, which can effectively meet the harsh outdoor use conditions, is not easy to be damaged and failed, and has strong anti-destructive force. The face buckle can choose a metal face buckle or a conventional plastic steel face buckle;

[0014] like Figure 3 , Figure 4 As shown, the female buckle 2 is provided with four female buckle notches 22 on the buckling surface, and the male buckle 3 is provided with two male buckle notches 32 on the buckling surface. By adding notches on the buckling surface, the buckling sound is smaller and crisper during buckling, the buckling force is more uniform, the use effect is good, and the use experience is excellent.

[0015] The beneficial effects of the utility model are: four rivets are arranged on the face buckle to fasten and fix it with the female buckle, the buckling force is large, the stability is good, the anti-destructive force is strong, it is not easy to be damaged and fail, it is easy to use, and the use requirements are effectively met.

[0016] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
