Abstract

The invention provides chain teeth of an anti-cracking zipper. Each chain tooth includes a tooth head and a tooth body arranged on the left side and right side respectively, and each tooth head and the corresponding tooth body are in transition connection through a tooth neck; the upper side and the lower side of each tooth head are each provided with a bulge, and the upper side and lower side of each tooth neck are each provided with a concave part; when one upper chain tooth is meshed with one lower chain tooth adjacent to the upper chain tooth, the bulges on any one chain tooth can be sunken in the concave parts of the other chain tooth, and mutual pressing force is generated between the bulges of one chain tooth and the tooth neck of the other chain tooth. Through the arrangement of the bulges and the concave parts, when the two chain teeth are meshed with each other, the bulges can apply acting force to the tooth necks, both longitudinal meshing force and transverse meshing force are formed between the chain teeth, the chain tooth meshing strength is largely improved, and the phenomenon that the chain teeth are disengaged and crack is effectively avoided.

Description

technical field [0001] The invention relates to a fastener element of a slide fastener, in particular to a fastener element of an explosion-proof slide fastener. Background technique [0002] Zipper is an indispensable product in people's daily life. It is convenient and fast to open and close, and has a wide range of applications. It is widely used in clothing, luggage and other products. [0003] The chain teeth are an essential part of the zipper. The traditional chain teeth have insufficient meshing strength. Under the strong pulling and pulling of external forces, the chain teeth are prone to bursting. Contents of the invention [0004] The invention provides a fastener element of an explosion-proof zipper, the main purpose of which is to overcome the defect that the fastener element is easy to disengage when the existing zipper is torn off by force. [0005] In order to solve the problems of the technologies described above, the present invention adopts the followin...
