Problems solved by technology

In the prior art, after the zipper meshes, there are gaps between the chain elements and the chain elements, and between the chain elements and the chain belt, which cannot achieve a completely airtight effect, and the waterproof effect is poor
Most of the existing waterproof zippers use waterproof cloth for waterproofing without belts, but the chain teeth still do not have waterproof function

Abstract

The invention relates to a closed zipper tooth and a closed shielding zipper. The closed zipper tooth comprises first teeth, second teeth and a cloth seam, the first teeth and the second teeth are fixedly arranged in a staggered mode, and a meshing cloth seam groove is formed in the front end, in the thickness direction, of a first tooth meshing head and the front end, in the thickness direction,of a second tooth meshing head after fixation; the closed shielding zipper comprises a puller, a left cloth tape, a right cloth tape, left zipper teeth, right zipper teeth and a locking piece, the left zipper teeth and the right zipper teeth are the staggered closed zipper teeth, the left zipper teeth are clamped on the left cloth belt, and the right zipper teeth are clamped on the right cloth belt; the left zipper tooth meshing convex parts of the left zipper teeth are mutually clamped with the right zipper tooth meshing grooves of the right zipper teeth, and the right zipper tooth meshing convex parts of the right zipper teeth are mutually clamped with the left zipper tooth meshing grooves of the left zipper teeth. According to the zipper teeth and the zipper composed of the zipper teeth, the space between the zipper teeth, the space between the zipper teeth and the cloth belt and the space between the zipper teeth and the zipper puller are all completely sealed, and the full-sealingfunction of the zipper is effectively achieved; the zipper is high in connection strength and rich in aesthetic feeling.

Description

technical field [0001] The invention belongs to the technical field of zippers, and in particular relates to a closed fastener element and a closed shielding zipper. Background technique [0002] 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, after the zipper meshes, there are gaps between the chain elements and between the chain elements and the chain belt, which cannot achieve a complete airtight effect, and the waterproof effect is poor. Most of the existing waterproof zippers adopt waterproof cloth for waterproofing without belts, but the chain teeth still do not have waterproof function. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the above defects, the present invention provides a closed element and a closed shielding zipper, which ...
