Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and in particular to a wear-resistant and anti-slip zipper structure. Background Technology

[0002] A zipper is a connector that uses continuously arranged teeth to join or separate items. There are many types of zippers, including nylon zippers, resin zippers, and metal zippers. A zipper consists of teeth, a slider, and top and bottom stops or locking parts. Among them, the teeth are the key part, as they directly determine the zipper's lateral tensile strength.

[0003] To this end, patent CN221949338U discloses a zipper structure, including a zipper body, a zipper head, and a stop. The stop is provided on the zipper body where the zipper head moves to the second end. The stop is made of soft material. On the side of the stop facing the first end, there is a through-hole and two baffles. The position of the through-hole corresponds to the position of the second end. The two baffles are arranged facing each other in the width direction of the stop. When the stop does not deform, the two baffles are used to prevent the zipper head from moving out of the second end, thereby improving the safety performance. In addition, when the stop deforms, the zipper head can be moved out of the second end, which is convenient for operation. The structure is compact and ingeniously designed.

[0004] The existing zipper structure is prone to damage to the pull tabs on the zipper head during use. Once damaged, replacement is difficult and affects the user experience. Utility Model Content

[0016] The above structure is used to limit the position of the pin.

[0017] Preferably, the protective structure includes a rust-proof layer and a wear-resistant layer, wherein the rust-proof layer is installed on the surface of the slider and the chain teeth, and the wear-resistant layer is installed on the surface of the rust-proof layer.

[0018] The above structure can provide some protection for the zipper pull and chain teeth, thus extending their service life.

[0019] The advantages of the wear-resistant and anti-slip zipper structure provided by this utility model are:

[0020] The disassembly and assembly structure allows the fixing ring and pull ring on the zipper head to be removed and replaced, improving replacement efficiency. The limiting structure can limit the pin to prevent it from coming off the block. The protective structure can protect the zipper head and chain teeth, extending their service life.

[0021] By using the designed disassembly and assembly structure, rotating the fixing rod causes the screw to disengage from the fixing rod, releasing the fixing restriction on the fixing ring. The fixing ring can then be removed, and the pull ring can be taken out, thus achieving the purpose of disassembly and replacement, improving replacement efficiency. At the same time, the fixing ring can also be replaced.

[0022] With the setting of the limiting structure, the pin is inserted into the block, the telescopic spring moves the block, the block enters the slot and engages with it, thus limiting the pin and preventing the pin from coming off the block.

[0023] The protective structure provides a rust-proof layer that protects the zipper pull and chain teeth from rusting, while the wear-resistant layer enhances their wear resistance, preventing wear during long-term use. Attached Figure Description
