Waterproof sealed open end zipper

Abstract

The invention discloses a waterproof sealing open-end zipper which comprises two zipper belts, a slide assembly, a square, a protrusion and a recess. Tracks which are used for being zipped with each other are respectively arranged on two close sides of the two zipper belts; the slide assembly is slidably arranged between the tracks of the two zipper belts in a combined manner and is used for driving the two zipper belts to be zipped with each other or separated from each other; the square is combined with the tail end of one of the zipper belts, so that the tail end of the other zipper belt can be fixedly inserted in the square; the protrusion is arranged at the tail end of one of the zipper belts, the recess is arranged at the tail end of the other zipper belt, and the protrusion of the zipper belt can be embedded into the recess of the other zipper belt after the tail end of the other zipper belt penetrates a guide groove of the slide assembly and is inserted into the square and the slide assembly is zipped, so that mutual sliding dislocation of the two zipper belts can be prevented.

Description

Technical field: [0001] The invention relates to a zipper, in particular to a track-type waterproof and sealed open-end zipper. Background technique: [0002] Today's waterproof and sealed zippers are mainly used in waterproof products, such as diving suits, raincoats, coats, waterproof bags, etc., to prevent water from infiltrating from the joints of the zipper; Two chain belts are made of plastic, and the corresponding surfaces of each chain belt form a track part, and each track part forms a convex rail and a groove, thereby connecting the track parts of the two chain belts through a zipper head, when sliding the zipper The track portions of the two chain belts can be linked (engaged) or separated from each other when the head is turned. However, the protruding rails and the grooves of the track portions of the above-mentioned two chain belts are elongated, and when they are linked (engaged) with each other, unlike the chain tooth engagement structure of the traditional ...

AI Technical Summary

Problems solved by technology

However, the clamping device used in the zipper is made of metal casting and assembly. Its biggest disadvantage is that the structure is too complicated and the structure volume is too large. If it is applied to a small zipper block, it will be cumbersome and cumbersome. Feeling, and one more step of clamping and fixing is required in use, which also causes inconvenience in operation and use
