Linear zipper tooth and zipper with linear zipper tooth

Abstract

The invention aims to provide a linear zipper tooth and a zipper with the linear zipper tooth. The linear zipper tooth can be prevented from tooth explosion and demeshing caused by a pressure or pulling and twisting when curved. The linear zipper tooth (1) comprises a clamping part (7), an inverted hook-shaped meshing part (3), a meshing groove (8), a caulking groove (4), an embossed stopper (5),and a fixture block (6), wherein one end of the clamping part (7) is provided with an open seam (2) to firmly clamp a zipper cloth belt, while a front side is provided with the second wall surface (12) of the linear zipper tooth (1); one side of the other end of the clamping part (7) is outwards extended to form the inverted hook-shaped meshing part (3) and the meshing groove (8) which correspondto each other; the back sides of the clamping part (7) and the meshing part (3) together form the first wall surface (11) of the linear zipper tooth (1); the caulking groove (4) is arranged in the centre of the outer wall of the other end of the meshing part (3), and corresponds to the open seam (2) in parallel; the embossed stopper (5) is positioned in the meshing groove (8) and arranged in the centre of the other end of the clamping part (7), and corresponds to the caulking groove (4) in parallel; and the fixture block (6) is protruded on the first wall surface (11) of the meshing part (3) and is adjacent to the caulking groove (4).

Description

technical field [0001] The invention relates to a metal or plastic-steel linear chain tooth and a zipper strip with the linear chain tooth. Background technique [0002] With the development of human social economy and science and technology, zippers have developed from the initial metal materials to non-metal materials, from a single variety with a single function to a multi-variety, multi-specification and comprehensive function. [0003] It has gone through a long process of evolution from simple structure to today's exquisite beauty. Its performance, structure, and materials are changing with each passing day, and it has a wide range of uses. It has penetrated into various fields such as aerospace, aviation, military, medical, and civil. sex and vitality. [0004] Zipper, seemingly insignificant, plays an indispensable soul role in daily life. Everything from clothes, pants, purses to shoes is related to zippers. When the zipper is working, it is almost forgotten that...

AI Technical Summary

Problems solved by technology

[0008] 1. The old-fashioned zipper strip 20, especially the metal zipper strip, in order to make it bendable, a clearance angle 110 is formed between the engaging part 120 and the engaging groove 130 to deflect each other, but the zipper strip 20 is bent at 150 degrees. Above or after pressing, the insertion groove 150 will not be able to effectively engage the two small blocks 140, so the curved part of the zipper strip 20 is prone to separation of the engaging portion 12 from the adjacent engagement groove 13, which not only affects the insertion groove 150 and the second stopper 140 are easy to cause damage, and will cause the zipper strip 20 to be used unsmoothly, and even cause the situation that the zipper strip 20 cannot be used in severe cases; Cause use not smooth or can't use, just become one of the problems that the present invention wants to improve

[0009] 2. The old sprockets 1 are arranged in a staggered arrangement with left and right sprockets. Since the combination effect between the sprockets 1 is not stable, when subjected to a large torsional force, pulling force or bending force, the meshing part 120 and Due to the influence of the meshing groove 130, it is easy to cause teeth bursting and chain disengagement. In other words, when the zipper bar 20 is bent, the chain teeth 1 will burst out and produce a raised situation. This not only easily scratches the user, but also makes the user Feel uncomfortable, thus reducing the value of the merchandise
