Abstract

The invention discloses a double-layer zipper. The double-layer zipper comprises a zipper base and a zipper strip, wherein the zipper base comprises a handle bracket, a handle, an upper zipper base and a lower zipper base; the zipper strip comprises an upper zipper strip, upper zipper cloth, a lower zipper strip and lower zipper cloth; the upper zipper cloth is connected with the upper zipper strip; the lower zipper cloth is connected with the lower zipper strip. During use, the double-layer zipper is arranged on a luggage case or a luggage bag, is provided with the upper zipper strip and the lower zipper strip, and is used for blocking the case opening of the luggage case or the bag opening of the luggage bag, and when the luggage case or the luggage bag is impacted, the upper zipper strip and the lower zipper strip can disperse an impact force on the case opening of the luggage case or the bag opening of the luggage bag, so that cracking of the case opening of the luggage case or the bag opening of the luggage bag can be avoided or reduced, and the strength of the zipper is improved; meanwhile, the theft-proof performance of the luggage case and the luggage bag is improved, and the difficulty for a lawbreaker to open the zipper through insertion of a sharp device is increased.

Description

technical field [0001] The invention relates to a safety zipper, in particular to a double-layer zipper. Background technique [0002] At present, the zippers used in suitcases or luggage bags often have the problem of zipper disengagement during use due to the insufficient strength of the zippers. At the same time, it is easier for lawbreakers to use pointed parts to insert the required zipper. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art and provide a double-layer slide fastener for improving the strength of the slide fastener and reducing the occurrence of the slide fastener disengagement problem. [0004] The technical scheme adopted in the present invention is: the double-layer zipper includes a chain seat and a chain, the chain seat includes a handle frame, a handle, an upper chain seat and a lower chain seat, and the chain includes an upper chain, an upper chain cloth, a lower chain and a l...
