Description

Technical Field

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

[0002] The lid and body of a bag are usually connected by a main zipper. In order to increase the capacity of the bag, a hidden expansion layer is usually set on the body or lid, which is connected by a telescopic cloth zipper. Pulling the zipper of the telescopic cloth can effectively increase the capacity. When not in use, zip up the telescopic cloth to restore the bag to its beautiful and simple appearance.

[0003] However, in the prior art, the zipper pulls on the main zipper and the telescopic zipper slide directly on the zipper teeth. The zipper teeth are usually made of lightweight plastic. Therefore, after the zipper pulls are pulled back and forth many times, the friction between the zipper pulls and the zipper teeth will cause the zipper teeth to wear out, and after a long time, the zipper teeth will break.
