Abstract

A multi-face zipper includes a pair of fastener tapes; a pair of sprocket rows respectively mounted on the pair of belts and each having a plurality of sprockets; a slider for engaging and disengaging the pair of element rows with and from each other; each chain tooth comprises an engaging part, a main body part and a connecting part which are connected in sequence, the pair of chain tooth rows are mutually engaged through the engaging parts, and the connecting part is connected with one chain belt; the front surface and/or the back surface of the zipper teeth are/is provided with a polyhedral structure; the polyhedral structure comprises a plurality of surfaces which are sequentially and continuously arranged along the direction from the connecting part to the main body part and gradually bulge outwards in the whole trend. The multi-surface structure is arranged, so that the meshing area between the zipper teeth is increased, the tensile capacity of the zipper is improved, and the reliability of the zipper is enhanced; in addition, the polyhedral structure also improves the integral stereoscopic impression of the zipper teeth, and the zipper teeth have more aesthetic property compared with the zipper teeth in the prior zipper.

Description

Multi-surface tooth zipper

Technical Field

The invention relates to the field of zipper manufacturing, in particular to a multi-surface tooth zipper.

Background

Slide fasteners are connecting members for joining or separating articles by means of continuously arranged fastener elements, and are widely used for clothing, bags, tents, and the like. The slide fastener generally comprises elements, a slider, an upper stop and a lower stop (a front stop and a rear stop) or a locking member. Each zipper is provided with a pair of chain belts, each chain belt is provided with a row of chain teeth, and the two rows of chain teeth are arranged in a staggered mode. The zipper teeth at two sides are clamped by the pull head, and the zipper teeth at two sides can be mutually meshed or separated by sliding the pull tab.

The existing zipper has small mutual meshing area of the zipper teeth, weak tensile capacity, easy occurrence of zipper bursting open when the zipper is used for a long time, and poor reliability.

Disclosure of Invention

The invention provides a multi-surface zipper, which mainly aims to overcome the defects of small mutual meshing area and poor reliability of zipper teeth of the conventional zipper.

In order to solve the technical problems, the invention adopts the following technical scheme:

a multi-face zipper comprises

A pair of chain belts;

a pair of sprocket rows respectively mounted on the pair of belts and each having a plurality of sprockets;

a slider for engaging and disengaging the pair of element rows with and from each other;

each chain tooth comprises an engaging part, a main body part and a connecting part which are connected in sequence, the pair of chain tooth rows are mutually engaged through the engaging parts, and the connecting part is connected with one chain belt;

the front surface and/or the back surface of the zipper teeth are/is provided with a polyhedral structure;

the polyhedral structure comprises a plurality of surfaces which are sequentially and continuously arranged along the direction from the connecting part to the main body part and gradually bulge outwards in the whole trend.

Further, the polyhedral structure also comprises a plurality of surfaces which are sequentially and continuously arranged along the direction from the main body part to the meshing part and have the overall trend of gradually protruding outwards.

Optionally, the polyhedral structure further comprises a plurality of faces which are successively arranged along the direction from the main body part to the engaging part and are gradually concave inwards in the whole trend.

Further, the polyhedral structure is a three-surface structure, a four-surface structure, a five-surface structure or a six-surface structure.

Compared with the prior art, the invention has the beneficial effects that:

the zipper is simple in structure and high in practicability, and the meshing area between the zipper teeth is increased by arranging the multi-surface structure, so that the tensile capacity of the zipper is improved, and the reliability of the zipper is enhanced; in addition, the polyhedral structure also improves the integral stereoscopic impression of the zipper teeth, and the zipper teeth have more aesthetic property compared with the zipper teeth in the prior zipper.
