Problems solved by technology

However, since this kind of zipper is molded directly on the chain belt by using a mold, once the size of the zipper is enlarged, that is, after the casting amount is increased, the chain belt will often be burned through or the chain belt cloth will be burned and deteriorated. Hardening and other bad conditions make the maximum model of this zipper only 8#, and once it breaks through 8#, the above-mentioned series of bad situations will easily occur
Regardless of the increase in the number of runners, the change of position, or the increase of casting flow rate and cooling rate, it is still difficult to prevent the occurrence of the above-mentioned series of adverse conditions.
Moreover, this kind of zipper needs to be electroplated after it is formed, otherwise its surface is not bright and is not suitable for product application. The larger the volume is, the more difficult it is to conduct electricity during electroplating, especially on zinc alloy materials.

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] figure 1 , figure 2 As shown, a zinc alloy zipper includes a chain element, a slider, and two chain straps 2. A row of chain teeth is respectively embedded in the opposite sides of the two chain straps 2, and the two rows of chain teeth are mutually misaligned and meshed. On the chain elements of the opposite side plates of the belt 2, each chain element includes an engaging portion 11 embedded in the chain belt and an engaging portion 12 for mutual engagement, and the engaging portion 11 includes an upper engaging portion 111 and an The lower engaging portion 112 located below the chain belt 2 , the upper engaging portion 111 and the lower engaging portion 112 are respectively U-shaped. The left and right sides of the engaging part 12 are respectively provided with snap-in rods 13, and the side of the engaging part 12 close...

Abstract

The invention relates to a zinc alloy zipper comprising zipper teeth, a slider and two zipper belts. The two sides, facing each other, of the two zipper belts are each provided with a row of zipper teeth; the two rows of zipper teeth are mutually staggered and engaged. The slider is clamped to the zipper teeth of the sides, facing each other, of the zipper belts. Each zipper tooth comprises a biting portion embedded in the corresponding zipper belt, and an engaging portion used for mutual engagement, wherein the biting portion comprises an upper biting portion and a lower biting portion, which are U-shaped. The problem that large zinc alloy zippers cannot be formed in the prior art is solved, the tensile strength of the zipper is greatly improved and the application range is wider.

Description

technical field [0001] The invention relates to a zinc alloy slide fastener. Background technique [0002] Chinese Patent No.: 201520098287.6 discloses a zipper with a simple structure that can prevent the teeth of the bite from being separated, including the teeth, the slider, and two chain belts. The opposite sides of the two chain belts are respectively embedded with a row of chain teeth and two rows The chain elements are misplaced and meshed with each other, and the slider is stuck on the chain elements of the opposite side plates of the chain belt. The chain elements include a head and a clamping rod arranged on the head between the head and the chain belt. The head A clamping part is provided on the side close to the other chain belt, and the clamping part is clamped on the clamping rod when the two rows of chain elements engage. This kind of slide fastener has good meshing performance, and the meshing of the two chain belts through the chain teeth basically cannot b...
