Description

Technical Field

[0001] The utility model relates to the technical field of anti-counterfeiting buckles, in particular to an anti-counterfeiting buckle and a packaging box. Background Art

[0002] At present, expensive items such as alcohol and decorations on the market are generally packaged in boxes. In order to effectively prevent and eliminate counterfeit and inferior products, some manufacturers use fastening anti-counterfeiting buckles to fasten the boxes, so that the boxes must be destroyed to open and cannot be restored again, thereby indirectly achieving the purpose of product anti-counterfeiting.

[0003] Traditional anti-counterfeiting buckles are mainly composed of male buckles and female buckles. The male buckle is embedded in the box body, and the female buckle is embedded in the bottom shell. The tongue on the male buckle is inserted into the slot on the female buckle, and the male buckle and the female buckle are buckled together to complete the locking of the packaging box. However, since traditional male buckles and female buckles are both molded with plastic materials, the male buckle and the female buckle are deformed and softened after artificial heating (for example, heating with a hot air gun). Pulling the box body and the bottom shell in the opposite direction can easily cause the tongue to disengage from the slot, and then the packaging box can be opened without damaging it, resulting in poor anti-counterfeiting effect. Utility Model Content

[0004] The utility model aims to solve the deficiencies in the prior art and provides an anti-counterfeiting buckle and a packaging box, which adopt a first metal spring and a second metal spring to avoid deformation and softening due to artificial heating, effectively prevent the tongue from falling out of the slot, and have a better anti-counterfeiting effect.

The first limiting block 221 corresponds to the first metal spring 121, and the second limiting block 222 corresponds to the second metal spring 122. The first metal spring 121 and the second metal spring 122 are both made of a high-temperature resistant metal material, such as stainless steel. In addition, the first metal spring 121 and the second metal spring 122 are elastic, so that the tongue 11 can be smoothly inserted into the slot 21.

[0035] When the latch tongue 11 is inserted into the slot 21 , the first metal spring 121 cooperates with the first limiting block 221 , and the second metal spring 122 cooperates with the second limiting block 222 to prevent the latch tongue 11 from being separated from the slot 21 .

[0036] The first limiting component 12 is arranged on the tongue 11, and the second limiting component 22 is arranged on the inner wall of the slot 21; by arranging the first limiting component 12 on the tongue 11, it is convenient to assemble the first metal spring 121 and the second metal spring 122 to the tongue 11, and the assembly is convenient. The second limiting component 22 is arranged on the inner wall of the slot 21, so that the first limiting block 221 and the second limiting block 222 can be formed on the inner wall of the slot 21 by injection molding, which is easy to produce and manufacture.

[0037] The first metal spring 121 and the second metal spring 122 are connected by a connecting piece 123, and the connecting piece 123 is installed on the tongue 11. Specifically, the first metal spring 121, the second metal spring 122 and the connecting piece 123 are integrally formed; by providing the connecting piece 123, the first metal spring 121 and the second metal spring 122 are connected to form a whole by using the connecting piece 123, and the connecting piece 123 is installed on the tongue 11 to complete the assembly of the first metal spring 121 and the second metal spring 122 to the tongue 11, which is convenient for assembly.

Specifically, the guard includes a first guard (not shown), a second guard (not shown) and a third guard (not shown). The first side plate 125 corresponds to the first guard, the second side plate 126 corresponds to the second guard, and the base plate 124 corresponds to the third guard.

[0041] The base plate 124 is provided with an extension plate 129, and the extension plate 129 is provided with an elastic portion 1291. The tongue 11 is provided with a groove 27 for inserting the extension plate 129, and the elastic portion 1291 abuts against the inner bottom wall of the groove 27, and the extension plate 129 abuts against the inner top wall of the groove 27. Specifically, the extension plate 129 extends horizontally, and the elastic portion 1291 extends downward from top to bottom in a direction away from the extension plate 129 inserted into the groove 27. The elastic portion 1291 is integrally formed with the extension plate 129; by arranging the extension plate 129 on the base plate 124 and arranging the elastic portion 1291 on the extension plate 129, during assembly, the extension plate 129 is inserted into the groove 27, the elastic portion 1291 abuts against the inner bottom wall of the groove 27, and the extension plate 129 abuts against the inner top wall of the groove 27, and the elastic supporting effect of the elastic portion 1291 is utilized to keep the entire U-shaped connector 123 and the latch 11 assembled stably to avoid loosening.

[0042] The inner wall of the card slot 21 is provided with a locking block 28 arranged opposite to it, and the lower surface of the locking block 28 has a guiding slope (not shown). The locking tongue 11 is provided with a locking groove 113 corresponding to the locking block 28, and the base plate 124 is provided with an avoidance hole 128 for the locking block 28 to pass through.

[0043] A first metal nail 23 corresponding to the first metal spring 121 is provided in the first limiting block 221, and a second metal nail 24 corresponding to the second metal spring 122 is provided in the second limiting block 222. The first metal nail 23 and the second metal nail 24 can both be formed of the same material as the first metal spring 121; by providing the first metal nail 23 and the second metal nail 24, when the anti-counterfeiting buckle is artificially heated and the male buckle 10 and the female buckle 20 are forcibly separated, the cooperation between the first metal nail 23 and the first metal spring 121, and the cooperation between the second metal nail 24 and the second metal spring 122 can further prevent the tongue 11 from detaching from the slot 21, and the female buckle 20 made of plastic material can wrap the first metal nail 23 and the second metal nail 24 after being heated, so that the first metal nail 23 and the second metal nail 24 are not easy to detach, thereby enhancing the anti-counterfeiting effect.

[0044] The first metal nail 23 and the second metal nail 24 are connected by a connecting rod 25. The first metal nail 23, the second metal nail 24 and the connecting rod 25 are integrally formed. By setting the connecting rod 25, the two ends of the connecting rod 25 are respectively connected to the first metal nail 23 and the second metal nail 24 to form an integral structure, which is easy to assemble.
