Problems solved by technology

[0002] Existing zipper products not only have the problem of not being innovative and high-grade in terms of structure, but also have the problem that the flat pull strength and bending strength of the zipper cannot be improved, so that most of the zippers cannot be easily pulled by external forces. Under strong pulling, it is very easy to produce a burst phenomenon that the chain teeth are disengaged
At present, for zippers designed to prevent chain teeth from bursting on the market, please refer to CN201520934119.6, a zipper disclosed in Chinese patent literature on April 13, 2016. Good, and the structure is complex, and the flat pull strength, bending strength and lightness of the zipper are not ideal

Embodiment Construction

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] Such as figure 1 , 6 Shown is a double-engagement zipper, the left and right chain elements A and B of the zipper are mutually engaged and fixed on the cloth tape 10 . The fastener element of the slide fastener of the present invention includes the engaging head 20 where the left and right fastener elements A and B mesh with each other, and the tooth root 30 engaged with the cloth tape 10 .

[0024] Such as Figure 2-8 As shown, the engaging head 20 of the present invention includes a first engaging head 21 and a second engaging head 22 . The...

Abstract

The invention discloses a double-meshing zipper. A first concave portion serving as a first meshing portion is formed between a first meshing head and a second meshing head of a meshing head of the zipper, a second concave portion serving as a second meshing portion is formed between the second meshing head and a tooth root, left zipper teeth and right zipper teeth are meshed, a first meshing head of one zipper tooth is meshed with a second meshing portion of the correspondingly meshed other zipper tooth, the second meshing head is meshed with a first meshing portion of the correspondingly meshed other zipper tooth, so that staggered meshing is formed, the width of the first meshing portion is smaller than that of the second meshing portion, and the width of the first meshing head is smaller than that of the second meshing head. Meshing stability of the zipper is achieved by smooth novel zipper tooth appearances, and flat tension strength is enhanced, so that the zipper has excellent bend flexibility and is softer.

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] Existing zipper products not only have the problem of not being innovative and high-grade in terms of structure, but also have the problem that the flat pull strength and bending strength of the zipper cannot be improved, so that most of the zippers cannot be easily pulled by external forces.
