Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a zipper assembly. Background Art

[0002] A zipper is a connecting piece that relies on continuously arranged teeth to join or separate items. Double-layer explosion-proof zippers are used in tools such as suitcases and bags for carrying when going out. However, the existing double-layer explosion-proof zippers have poor explosion-proof effects. When subjected to expansion force and local tension, the pull head of the double-layer explosion-proof zipper is prone to bending with a small curvature. Over time, this will cause separation and easy sliding between the pull head and the zipper tooth row, and in severe cases, the teeth will not mesh tightly.

[0003] The Chinese patent discloses a double-layer explosion-proof zipper (authorization publication number CN214594576U). This patented technology solves the problem that the existing double-layer explosion-proof zippers have poor explosion-proof effects. When subjected to expansion force and local tension, the pull head of the double-layer explosion-proof zipper is prone to bending with a small curvature. Over time, this will cause separation and easy sliding between the pull head and the zipper tooth row, and in severe cases, the teeth will not mesh tightly.

[0004] However, it has certain drawbacks: its fixing piece is made of elastic plastic, and the fastening block is made of metal and is mushroom-shaped. By hard-pressing the fastening block to make it stuck inside the fixing piece, the position of the fixing piece is fixed. Therefore, the fixing piece is also very easy to detach from the outside of the fastening block due to external forces such as pulling and collision. And as the use time increases, the inner side of the fixing piece is also very easy to wear, so that it cannot be stably sleeved outside the fastening block, thereby reducing the protection effect.
