CN2292428Y - Watertight zipper - Google Patents

Abstract

The utility model discloses a watertight zipper, comprising the zipper; the watertight zipper is characterized in that the zipper is composed of two concave convex chains which are from top to bottom arranged in parallel, wherein, the concave convex chain railway of one concave convex chain can be correspondingly matched with the concave convex chain railway of the other concave convex chain, and the concave convex chain railways can be locked, opened and closed through the same zipper. The water tight zipper has intensity and function as the general zipper, and has excellent water leak-proof effect; because the upper and the lower chain railways can be synchronously opened and closed through the same zipper, and the watertight zipper has convenient utilization.

Description

Waterproof slide fastener

The utility model relates to a kind of slide fastener, is a kind of waterproof slide fastener specifically.

Traditional slide fastener is a strand rail structure, mainly plays the connection effect, does not have the water-impervious function.

The purpose of this utility model is to provide a kind of and has many chain rail structures, and the waterproof slide fastener with water-impervious function.

To achieve these goals, the utility model adopts following technical scheme: a kind of waterproof slide fastener, comprise zip, it is characterized in that: slide fastener is made up of the upper and lower two concavo-convex chains that be arranged in parallel, the corresponding coupling of concavo-convex chain rail on the concavo-convex chain rail on the concavo-convex chain and another concavo-convex chain wherein, and realize the locking folding by same zip.

Good effect of the present utility model is: the good molecular structure of employing pliability elastic material is closely made concavo-convex chain up and down, when concavo-convex chain is in by locking states up and down, many the uneven separately interlocks of chain rail, form a closed structure, make its intensity that not only has common slide fastener and function, have more fabulous percolation-proof effect, and owing to multichain rail about it passes through same chain lock synchronous on-off, extremely easy to use.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is a concavo-convex chain structure schematic diagram in preferred embodiment of the utility model;

Fig. 2 is that A-A cuts open schematic diagram among Fig. 1;
