An oblique tooth plastic steel zipper

Abstract

The invention discloses an inclined-tooth plastic steel zipper. Left zipper teeth and right zipper teeth are injection-molded on a cloth belt in an inclined mode; each meshing part comprises a first meshing part body and a second meshing part body; the first meshing part bodies are meshing head parts formed at the ends of the zipper teeth, and the top end of each meshing head part is provided with a first tooth tip; each second meshing part body is a tooth head meshing groove formed between the corresponding meshing head part and a matching part in a concave mode, and a tooth tip meshing groove is formed in each tooth head meshing groove in a concave mode; meshing of the left zipper teeth and the right zipper teeth is conducted through alternative meshing between the corresponding meshing head parts and the tooth head meshing grooves and between the tooth tips and the tooth tip meshing grooves. The appearance of the zipper is simple and attractive, the individual needs of consumers can be met, the meshing force is higher, and the requirement on the structure of a puller is low.

Description

technical field [0001] The invention relates to a zipper, in particular to the improvement of the fastener element structure of the zipper. Background technique [0002] The traditional zipper combination method is dislocation and interlocking. The tooth head part similar to the chain teeth is designed as a straight line. It is difficult to form a certain geometric shape in appearance after the left and right chain teeth are meshed. This will cause consumers' aesthetic fatigue during long-term use. Not only can't meet the individual needs of consumers, but also there are problems such as insufficient meshing strength of the tooth head part. In order to solve the problem of zipper meshing strength, the structure of the slider is mostly improved, which makes the structure of the slider too complex, resulting in poor pull-to-self-locking force and other poor physical properties of the zipper, which affects the overall quality of the zipper.
