Zipper wire material and zipper tooth made of zipper wire material

Abstract

The invention relates to a zipper wire material, which is in a linear state. A main body of the zipper wire material comprises a head part and a pair of leg parts, wherein cross section leg parts of the linear main body are arranged at two sides of the main body and outsides extend so that the two leg parts are in an open state, the leg parts comprise leg claws, the leg claws are arranged at the end parts of the leg parts, the main body comprises an inner main body and a covering layer, and the covering layer for enhancing the metal intensity and the oxidation resistance capability of the zipper wire material is covered and pressed outside the inner main body. The invention also provides a zipper tooth made of the zipper wire material. The zipper tooth has the technical characteristics identical to that of the zipper wire material. Because the zipper wire material and the zipper tooth are provided with the covering layer, the covering layer has better metal intensity and oxidation resistance capability, and the physical performance and the oxidation resistance capability of the zipper wire material and the zipper tooth can be improved through the arrangement of the covering layer.

Description

technical field [0001] The invention relates to a zipper wire and a chain element, in particular to a metal zipper wire and a metal chain element. Background technique [0002] Zippers are used in various fields such as leather goods and clothing. Common zippers can be divided into nylon zippers, injection molded zippers and metal zippers, and metal zippers are usually divided into aluminum zippers, copper zippers, and iron zippers. High-end zipper wires are usually made of metal materials such as aluminum, copper or iron, and with the advancement of zipper technology, zinc zippers have also appeared. [0003] However, the metal strength of aluminum is low, so the zipper wire made of aluminum is soft, causing the zipper to be easily deformed and not up to standard; while iron has sufficient metal strength, but the oxidation resistance of iron is poor, so the zipper made of iron Wire or post-production zippers are prone to rust; Zinc zipper wires have the same problem of ins...

AI Technical Summary

Problems solved by technology

[0003] However, the metal strength of aluminum is low, so the zipper wire made of aluminum is soft, causing the zipper to be easily deformed and not up to standard; while iron has sufficient metal strength, but the oxidation resistance of iron is poor, so the zipper made of iron Wire or post-production zippers are prone to rust; Zinc zipper wires have the same problem of insufficient metal strength as aluminum zipper wires; copper has sufficient metal strength and oxidation resistance, so copper zippers are more common, but The price of copper is higher, so the price of copper zipper wire is higher

[0004] The chain teeth are made of zipper wire, which leads to the above-mentioned problems in the chain teeth
