布袋覆盖牙拉链
By incorporating abrasion-resistant fabric into the zipper, direct contact between the zipper head and teeth is isolated. The abrasion-resistant fabric is used to transmit pressure, thus solving the problems of wear and contamination during the zipper engagement process and achieving zero-contact abrasion prevention and efficient meshing.

AI Technical Summary
During the zipper engagement process, the direct contact and friction between the zipper head and the zipper teeth cause wear and deformation, especially during high-speed operation. Furthermore, current technology cannot effectively isolate the direct contact between the zipper head and the zipper teeth, leading to wear and contamination problems.
Abrasion-resistant cloth is placed on the outer surface of the chain belt, covering the space between the chain head and the chain teeth. The abrasion-resistant cloth is used as a pressure transmission medium. It absorbs the instantaneous impact kinetic energy through flexible deformation, isolates the direct contact between the chain head and the chain teeth, and transforms the rigid pressure of the chain head into a uniformly distributed pressure, which promotes the meshing of the chain teeth.
It achieves zero-contact wear prevention, eliminates instantaneous impact wear on the chain teeth surface, optimizes chain engagement efficiency and reliability, and avoids direct contact wear and contamination of the chain teeth.
