Abstract

The invention belongs to the technical field of zippers, and relates to a staggered dustproof chain tooth and a dustproof airtight zipper. The chain tooth comprises a first mi tooth and a second mi tooth which are arranged in a staggered mode and a cloth tape seam. The first mi tooth comprises a first mi tooth body, a first mi tooth meshing groove and a first mi tooth head convex part; the secondmi tooth comprises a second mi tooth body, a second mi tooth meshing groove and a second mi tooth head convex part; the upper surfaces of the first mi tooth head convex part and the second mi tooth head convex part are provided with mi tooth cloth tape seam grooves; shoulder convex parts are arranged at the positions, close to the cloth tape seam, of the first mi tooth meshing groove and the second mi tooth meshing groove; and the thickness of the shoulder convex parts is not greater than the concave degree of the mi tooth cloth tape seam grooves. The zipper comprises a left cloth tape, a right cloth tape, left chain teeth and right chain teeth, and the left chain teeth and the right chain teeth are meshed with each other; and the left chain teeth and the right chain teeth are staggered dustproof chain teeth. The dustproof zipper tooth is in a staggered shape, the zipper formed after meshing of the tooth is good in sealing function, and the dustproof effect is good; and the appearanceis beautiful, and the formed dustproof airtight zipper has good dustproof and sealing effects.

Description

technical field [0001] The invention belongs to the technical field of zippers, and in particular relates to a misplaced dust-proof chain element and a dust-proof airtight zipper. Background technique [0002] Dust-proof clothing is a protective clothing that protects the relevant workers from dust pollution and harms the skin. It is used in mining, building materials, chemicals, metallurgy, food, medicine, military industry and other industries, and zippers are widely used as a simple and fast connector. In the production of protective clothing. The zipper is composed of chain elements, sliders, limit codes or locking parts, etc., usually two chain belts, each with a row of chain teeth, and the two rows of chain teeth are arranged alternately. In the prior art, there are gaps between the fastener elements and the cloth tape after the fastener elements are meshed, and there are gaps between the fastener elements, which do not have a dust-proof and airtight effect, and canno...
