Abstract

The invention relates to a multi-surface tooth zipper, which comprises a pair of zipper belts, a pair of zipper tooth rows, wherein the pair of zipper tooth rows are respectively mounted on the pair of zipper belts and each has a plurality of zipper teeth, a pull head, wherein the pull head is used for enabling the pair of zipper tooth rows to be mutually meshed and separated; each zipper teeth comprises a meshing part, a main body part and a connecting part which are sequentially connected, the zipper tooth rows are mutually meshed through the meshing parts, and the connecting part is connected with the zipper belt; the front surface and / or the back surface of the zipper teeth are / is provided with a polyhedral structure; the polyhedral structure includes a plurality of surfaces which aresequentially and continuously arranged in the direction from the connecting part to the main body part and have an overall tendency to gradually outwardly bulge. By arranging the polyhedral structure,the meshing area between the zipper teeth is increased, thereby the tensile capacity of the zipper is improved and the reliability of the zipper is enhanced; in addition, the polyhedral structure also improves the overall stereoscopic impression of the zipper teeth, and makes the multi-surface zipper teeth more attractive compared with the zipper teeth in the prior zipper.

Description

technical field [0001] The invention relates to the field of zipper production, in particular to a multi-faced tooth zipper. Background technique [0002] Zipper is a connecting piece that relies on continuous arrangement of chain teeth to make items merge or separate, and is now widely used in clothing, bags, tents, etc. Zippers are generally composed of chain teeth, sliders, upper and lower stops (front code and rear code) or locking pieces. Each zipper has a pair of chain belts, each chain belt has a row of chain teeth respectively, and the two rows of chain teeth are alternately arranged. The slider clamps the chain elements on both sides, and slides with the help of the pull tab, so that the chain elements on both sides can be engaged or disengaged from each other. [0003] Due to the small meshing area of ​​the elements of the existing slide fasteners, the tensile strength is relatively weak, and the slide fasteners are prone to bursting when used for a long time, an...
