[0021] LABEL EXPLANATION

[0022] Buckle shell 1, surrounding part 11, upper protecting edge 12, lower protecting edge 13, through hole 131,

[0023] Integrated buckle piece P: face part 2, upper annular face 21, middle annular face 22, lower annular face 23,

[0024] Foot receiving cavity 210, foot hole 211, reinforcing partition column 212, anti-skid convex particle 213,

[0025] Ring portion 3, tongue-cutting piece 4, female buckle cavity 40, elastic tongue buckle portion 41, vertical portion 411, curved portion 412.

[0026] Inner ring edge 421, outer ring edge 422. Detailed Implementation

[0027] The following detailed description of this case is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] This case involves a simple type of female clasp, such as Figures 1-6 As shown, it consists of two parts: the snap-on housing 1 and the integrated snap-on piece P.

[0029] The one-piece fastener P has a cover structure, including an integrally formed face 2 and a ring 3. The fastener housing 1 surrounds the one-piece fastener P. Specifically, the fastener housing 1 has a surrounding part 11, an upper guard edge 12, and a lower guard edge 13. The surrounding part 11 is configured to surround the ring 3. The upper guard edge 12 limits the periphery of the face 2, and the lower guard edge 13 limits the edge (free end) of the ring 3. The one-piece fastener P is securely installed inside the fastener housing 1.

[0030] At least two tongue pieces 4 are punched along the unclosed contour on the face 2. The at least two tongue pieces 4 are bent toward the center of the integral fastener P to form an elastic tongue fastener part 41. The space enclosed by the at least two elastic tongue fastener parts 41 forms a female fastener cavity 40.

[0031] To facilitate the formation of an appropriate depth in the female buckle cavity 40, the tongue piece 4 is first bent vertically towards the side where the ring portion 3 is located, and then partially rolled up to form the elastic tongue buckle portion 41, which includes a vertical portion 411 and a rolled portion 412. The winding angle of the rolled portion 412 is preferably at least 180 degrees.

[0032] Typically, the female buckle cavity 40 is circular. Therefore, the number of tongue-cutting pieces 4 directly affects the smoothness of the circular structure of the female buckle cavity 40. At least two tongue-cutting pieces 4 are provided, preferably 2-9. In a specific embodiment, five tongue-cutting pieces 4 are evenly distributed in a ring, forming five elastic tongue-fastening portions 41 arranged in a circular pattern. Furthermore, the tongue-cutting pieces 4 have a tongue-shaped structure, which facilitates bending into an arc-shaped elastic tongue-fastening portion 41, thereby enhancing the smoothness of the female buckle cavity 40 formed by it and facilitating the female buckle fastening operation.

[0033] The design of the female buckle structure in this case is very simple. The main component is just a one-piece buckle P with a one-piece design. The parts are simplified to the minimum, which brings about an outstanding thin and light functional design. Moreover, the production and assembly are very simple, the cost is low, and the quality is excellent.

[0034] Preferably, the elastic tongue buckle part 41 needs to be properly hidden design, which ensures the stability of the female buckle structure and the overall appearance modeling. In a specific embodiment, the lower guard edge 13 is extended to the center, and the center is provided with a through hole 131, the diameter of the through hole 131 corresponds to the female buckle cavity 40, and the through hole 131 constitutes the cavity opening of the female buckle cavity 40.

[0035] Of course, the diameter of the through hole 131 needs to be moderate, which realizes the proper hidden design of the elastic tongue buckle part 40, and at the same time, the function of the elastic tongue buckle part 40 needs to be considered. Preferably, the corresponding bending part 412 of the elastic tongue buckle part 41 has the minimum and maximum inner ring edges 412a and outer ring edges 412b, and the hole of the through hole 131 is between the inner ring edge 412a and the outer ring edge 412b.

[0036] Preferably, the elastic tongue buckle part 41 and the lower guard edge 13 have a small gap, that is, the bending part 412 and the lower guard edge 13 have a small gap, and it is best that they cannot contact each other. In a specific embodiment, the edge of the relative ring part 3 is slightly sunken horizontally, which can ensure the elasticity of the elastic tongue buckle part 41 and minimize the gap of the female buckle cavity 40, thereby avoiding defects such as accumulation of hooks and lines.

[0037] Preferably, the face part 2 is designed as a three-layer ring surface from the center to the outside, which is an upper ring 21, a middle ring 22 and a lower ring 23. The thickness of the middle ring 22 is not greater than the thickness of the upper guard edge 12. After the one-piece buckle P is assembled on the upper buckle shell 1, the middle ring 22 corresponds to the raised layer of the back of the female buckle, which improves the flatness of the back of the female buckle and improves the adhesion between the material and the whole female buckle. The middle ring 22 is not higher than the upper guard edge 12, and the thickness of the two is preferably equal, so that the middle ring 22 is flush with the upper guard edge 12. In the horizontal direction, the upper ring 21 is at least partially protruding from the upper guard edge 12, and when the middle ring 22 is flush with the upper guard edge 12, the upper ring 21 is completely protruding from the upper guard edge 12. The upper ring 21 is provided with a foot hole 211, and the inner side of the upper ring 211 is formed with a foot connecting cavity 210, which is beneficial to the cooperation and assembly of the female buckle and the related foot.

[0038] Preferably, the upper ring 21 is bent and recessed in the direction of the foot connecting cavity 210 to form a plurality of reinforcing partition columns 212, which play a role in reinforcing and partitioning the foot connecting cavity 210.

[0039] Preferably, the upper ring 21 is bent and recessed in the direction of the outer side to form a plurality of anti-skid convex particles 213, which play a role in anti-skid in the assembly application (such as installation on clothes). The reinforcing partition column 212 also cooperates with the anti-skid convex particle 213 to form a concave-convex structure, which plays a more excellent anti-skid role.

[0040] The above merely describes the preferred embodiments of the present application, and any equivalent changes and modifications made within the scope of the present application should be covered by the claims of the present application.
