Description

Technical Field

[0001] The utility model relates to the technical field of chain teeth, in particular to a hidden chain tooth provided with a guide anti-dropping structure. Background Art

[0002] The chain teeth are part of the zipper. They are connected by continuously arranged chain teeth to make objects join or separate. The left and right groups of chain teeth bite each other in an alternating manner to achieve a locking effect.

[0003] In actual use, the chain teeth of most zippers now mainly cooperate with each other through the round head at the inner end and the depression in the middle to achieve the effect of mutual locking. However, some zipper block bodies will cause the chain teeth on the left and right sides to be misaligned in a front-to-back manner during the sliding process, making it difficult for the chain teeth on the left and right sides to bite. At the same time, the chain teeth exposed for a long time are also easily impacted by external forces, causing misalignment in the front-to-back direction, which will lead to bite failure, jamming, and difficulty in disassembly.

[0004] Therefore, we propose a hidden chain tooth with a guide anti-dropping structure to solve the above-mentioned problems. Utility Model Content
