Tooth covering top stopper, metal zipper with special function and using method of zipper

Abstract

The invention relates to a tooth covering top stopper, a metal zipper with a special function and a using method of the zipper. The tooth covering top stopper comprises a front clamping copper sheet,a rear clamping copper sheet and a transition copper sheet, a front transverse notch is formed in the middle of the front clamping copper sheet, a rear transverse notch is formed in the middle of therear clamping copper sheet, and the transition copper sheet comprises an upper transition copper sheet, a lower transition copper sheet and a transition channel; the metal zipper comprises a left cloth belt, a right cloth belt, left zipper teeth, right zipper teeth, a puller, a left top stopper assembly and a right top stopper, wherein the right top stopper is the tooth covering top stopper. The left top stopper assembly comprises a left copper piece, a first rivet, a second rivet and a spring connecting piece, the first rivet, the second rivet and the spring connecting piece are arranged on the outer surface of the left copper piece, the spring connecting piece is of an S-shaped structure, and the corresponding central angle of an arc at the bent transition position of the spring connecting piece ranges from 75 degrees to 135 degrees. The tooth covering top stopper is fixed on the cloth belt after being embedded with the zipper teeth, so that the connection strength is high; the metalzipper with the special function can be separated from the upper end or the lower end of the zipper belt, quick disassembly of the zipper is achieved, and the zipper is convenient to use and long inservice life.

Description

technical field [0001] The invention belongs to the technical field of zippers, and in particular relates to a metal zipper with a top stop and special function and a method for using the zipper. Background technique [0002] The zipper is a connecting piece that relies on the chain teeth arranged continuously to make the items merge or separate. The zipper is composed of chain teeth, sliders, upper and lower stops or locking parts, etc. Generally, the zipper has two chain belts, and each chain belt has its own There is a row of chain teeth, two rows of chain teeth are arranged alternately, the slider clamps the chain teeth on both sides, and slides with the help of the pull tab, so that the chain teeth on both sides can be meshed or disengaged. Zippers in the prior art generally include nylon zippers, resin zippers, and metal zippers according to materials. Because the metal zipper material is strong, it is usually used on jeans, coats and backpacks. [0003] Existing zipp...

AI Technical Summary

Problems solved by technology

However, the smoothness of this type of zipper depends on the cooperation of the chain teeth for a long time. In special occasions, it cannot be quickly disengaged. Single, cumbersome, and time-consuming; violent disengagement will affect the service life of the zipper, and even the zipper cannot be reused, resulting in waste of resources

For metal chain teeth, due to the strong material of the metal chain teeth, the slider is easily damaged when the slider is pulled hard, and it needs to be replaced regularly. The replacement operation is inconvenient and the service life of the zipper is low.
