Traditional injection moulding chain tooth in order to prevent separations of staggering before and after its, need be offered groove in the crest portion of chain tooth after intermeshing, the shoulder at root of the tooth forms and the convexity of groove fit to prevent to stagger simultaneously.Since groove with convex to form the field of conjugate action at the chain tooth, it is complex-shaped, precision is high, design for Injection Mould all has big difficulty with processing.

Summary of the invention

The technical problem that the present invention will solve provides a kind of simple in structure, need not high-precision processing, and can make the chain tooth that it is to be enough to other sign of outlook.

The technical scheme that adopts for solving the problems of the technologies described above: a kind of slide fastener coupling element; It is characterized in that: the side, front side at least of said chain tooth both sides before and after slide fastener is formed with a platform; This platform is in aggregates in two side chain teeth engagement back butt joint; With respect to the whole piece slide fastener, the covering that this integral body is alternately exposed chain tooth engaging piece to the side realization of two side chain teeth.

On the basis of the above, said platform is made as offset.Concrete, said platform is square, and it is offset to a chain tooth wherein side of both sides up and down, and wherein the butt end of platform to be exposing the crest portion of chain tooth, and its end that departs from is to expose the depressed part corresponding to the tooth waist of the chain tooth of this end.

Adopt the beneficial effect that the present invention brought: because the present invention can be to being connected into whole platform after the leading flank of chain tooth or front and back sides form engagement; Platform is to after being connected into integral body; Side to two side chain teeth covers, and after the slide fastener engagement, the engaging piece of chain tooth is alternately exposed in this covering.Chain tooth among the present invention is after intermeshing, and platform stops mutually on fore-and-aft direction the chain tooth of both sides, can prevent that the chain tooth from staggering after engagement and separate.Therefore need not to form groove and convexity, make the simplifying the structure of chain tooth, reduce the difficulty of Injection Mold Design processing at the field of conjugate action of chain tooth.

Side at the chain tooth is provided with platform; Like this can be in signs such as pattern after making split respectively on the platform of intermeshing two side chain teeth and literal; To after being connected into integral body, being spliced into by signs such as the pattern of both sides and literal it is to be enough to other full identity of outlook at platform.Because the chain tooth has occupied the whole piece slide fastener basically, making traditional can only on pull head and pulling-on piece, the making of sign contrast on the chain tooth, be more prone to cause concern, more help the propaganda of product.And some make exquisite pattern or literal, also can give slide fastener as product the sight that must give bring great innovation, to enhance one's market competitiveness.
