Zipper

Abstract

The invention belongs to the technical field of zippers, in particular to a zipper. The zipper comprises zipper tapes, zipper heads and zipper teeth; cavities are formed in the zipper tapes, and elastic waveform plates are mounted on the two sides of the corresponding cavity; clamping blocks are arranged in wave troughs of the elastic waveform plates, and rotation rods are arranged on the clampingblocks; the zipper teeth are arranged on the upper end faces of the zipper tapes and connected with the rotation rods through bearings; the rotation rods penetrate through the zipper teeth and are rotatably connected with rotation wheels; the missing zipper teeth are subjected to position covering, when the position of the last zipper tooth covers the missing position, pulling of the zipper headscontinues, and the zipper tooth subjected to position covering is closed with the zipper teeth which are symmetrically arranged at intervals; when pulling of the zipper heads continues, first racks on first vertical plates mesh with the outer side faces of the rotation wheels and accordingly drive the vertical clamping blocks to continue to be clamped into the wave troughs of the elastic waveformplates, accordingly, the zipper teeth subjected to position covering are fixed, and the situation is avoided that the zipper teeth shake and accordingly influence the overall closing effect of the zipper tapes.

Description

technical field [0001] The invention belongs to the technical field of slide fasteners, in particular to a slide fastener. Background technique [0002] Zipper is a connecting piece that relies on continuous arrangement of chain teeth to make items merge or separate. It is now widely used in clothing, bags, tents, etc.; The functional characteristics of the zipper teeth are also increasingly paid attention to. [0003] However, existing zipper tapes, zipper teeth and zipper pullers are all used in conjunction with each other. If the zipper teeth on the zipper tape are damaged or detached, the closing performance of the zipper tape is likely to be reduced, making the zipper prone to failure during use. Disengagement phenomenon, and then need to disassemble and replace the whole zipper tape, so that the zipper on the clothes can be closed, and then the zipper that is replaced or disassembled is easy to cause waste or when the zipper tape is not completely disassembled, it is ...

[0003] However, existing zipper tapes, zipper teeth and zipper pullers are all used in conjunction with each other. If the zipper teeth on the zipper tape are damaged or detached, the closing performance of the zipper tape is likely to be reduced, making the zipper prone to failure during use. Disengagement phenomenon, and then need to disassemble and replace the whole zipper tape, so that the zipper on the clothes can be closed, and then the zipper that is replaced or disassembled is easy to cause waste or when the zipper tape is not completely disassembled, it is easy to cause damage or damage to the clothes
