[0026] Reference Figures 1-4 The image shown is a preferred embodiment of the present invention.
[0027] This utility model provides an anti-counterfeiting buckle female buckle structure, including a female buckle body, the female buckle body including an installation part and a fastening part, the fastening part is provided with a fastening cavity for cooperating with the male buckle, and fastening sidewalls are formed on both sides of the fastening cavity; the two fastening sidewalls are arranged opposite each other, and the fastening sidewalls are provided with a first elastic protrusion 200 and a second elastic protrusion 210 extending downward, the two second elastic protrusions 210 being respectively arranged on both sides of the first elastic protrusion 200;
[0028] The bottom of the first elastic protrusion 200 has a first inverted tooth 201 that bends toward the center of the fastening cavity, and the bottom of the second elastic protrusion 210 has a second inverted tooth 211 that bends toward the center of the fastening cavity; the mounting part and the fastening part are arranged in an upper and lower structure, and the mounting part is provided with a fastening structure for fastening the female buckle body onto the carrier.
[0029] The aforementioned anti-counterfeiting buckle female buckle structure, through the cooperation of the first elastic protrusion 200, the first reverse tooth 201 arranged opposite to each other on both sides, and multiple second elastic protrusions 210 and second reverse teeth 211, forms multiple reverse locking mechanisms after the male buckle is inserted, effectively preventing it from falling off. Combined with the locking structure, it can be securely assembled to the carrier, improving the overall connection reliability and ease of use of the anti-counterfeiting buckle, and providing strong anti-counterfeiting capabilities. Along the depth direction of the locking cavity, the first reverse tooth 201 is lower than the second reverse tooth 211.
[0030] Specifically, the main body of the female buckle is made of ABS plastic.
[0031] In a preferred embodiment, a front wall is formed on the front side of the fastening cavity. The front wall has a downwardly extending third elastic protrusion, the bottom of which has a third undercut 300 bent towards the center of the fastening cavity. The third elastic protrusion and the third undercut 300 of the front wall, together with the structures on both sides, provide more repeated reverse clamping of the male buckle, enhancing the anti-detachment effect, making the female buckle more securely assembled with the carrier, and improving the overall reliability and practicality of the anti-counterfeiting buckle.
[0032] Along the depth direction of the fastening cavity, the third reverse tooth 300 is located between the first reverse tooth 201 and the second reverse tooth 211. In this way, the front wall of the fastening is provided with a third elastic protrusion and a third reverse tooth 300. Along the depth of the fastening cavity, its reverse tooth is located between the first and second reverse teeth. It cooperates with the structures on both sides to lock the male buckle in multiple reverse directions, strengthen the anti-disengagement, and improve the assembly stability of the female buckle and the reliability of the anti-counterfeiting buckle.
[0033] Specifically, the outer perimeter of the bearing plate has a U-shaped arc shape.
[0034] Reference Figure 4 As shown, during the process of the male clasp being inserted into the engagement cavity from top to bottom, the second reverse tooth 211, the third reverse tooth 300, and the first reverse tooth 201 sequentially engage with the multiple grooves on the outer periphery of the male clasp.
[0035] In a preferred embodiment, a snap-fit rear wall is formed on the rear side of the snap-fit cavity. A downwardly extending guide plate 400 is provided on the snap-fit rear wall, and an inwardly recessed guide groove 401 is provided on the guide plate 400. The guide groove 401 extends along the extending direction of the guide plate 400. Thus, the guide plate 400 and guide groove 401 of the snap-fit rear wall provide precise guidance for the insertion of the male snap fastener. Combined with the elastic protrusions and barbs on the front and sides, this facilitates smooth insertion of the male snap fastener and enhances the anti-detachment effect through multiple locking mechanisms, further improving the ease of use and connection reliability of the anti-counterfeiting snap.
[0036] Specifically, the mounting section and the fastening section are molded as a single piece. This ensures overall strength.
[0037] The mounting section includes a support plate 100, the middle of which has a through hole 101 for the male buckle to be inserted downward into the fastening cavity. Thus, the through hole 101 in the support plate 100 of the mounting section provides a channel for the male buckle to be inserted into the fastening cavity, allowing the male buckle to be smoothly inserted downwards for engagement.
[0038] The bottom of the support plate 100 has a downwardly protruding lower ring 110, and the tops of a plurality of first elastic protrusions 200, the tops of second elastic protrusions 210 and the tops of third protrusions are connected to the lower ring 110.
[0039] The locking structure includes multiple peripheral notches 111. The lower convex ring 110 has an annular peripheral wall on its outer periphery, and multiple inwardly recessed peripheral notches 111 are provided on the peripheral wall. In this way, a stable locking connection can be formed with the carrier. Combined with the aforementioned multi-tooth anti-detachment design, it not only improves the firmness of the female buckle and the carrier assembly, but also ensures the reliability of the male buckle connection, further optimizing the anti-counterfeiting buckle performance.
[0040] In a preferred embodiment, the engaging structure includes multiple engaging holes 102. The support plate 100 has multiple engaging holes 102 that penetrate vertically through the support plate 100, and these engaging holes 102 are arranged around the outer periphery of the through holes 101. This allows for a secure engagement with the corresponding structure of the carrier.
[0041] Specifically, multiple peripheral notches 111 and multiple engaging holes 102 are arranged in a one-to-one correspondence, and the peripheral notches 111 and the corresponding engaging holes 102 are interconnected. This creates a continuous, coordinated fixing mechanism, enhancing the tightness of the fit with the carrier. Combined with the guiding and multiple reverse-tooth design, this improves the stability of the female buckle assembly and ensures the male buckle connection is secure, further optimizing the overall reliability and performance of the anti-counterfeiting buckle.
[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
