Description

Anti-theft double zipper

technical field

The invention relates to a safety slide fastener, in particular to an anti-theft double-layer slide fastener.

Background technique

At present, the zippers used in suitcases or luggage bags are not strong enough. In the process of use, criminals insert a sharp object into the zippers to slit the zippers. It becomes necessary to improve zipper strength and anti-theft.

Contents of the invention

The object of the present invention is to overcome the deficiencies of the prior art and provide an anti-theft double-layer slide fastener for improving the strength of the slide fastener and the anti-theft performance of the slide fastener.

The technical scheme adopted in the present invention is: the anti-theft 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 The lower chain cloth, the upper chain cloth is connected with the upper chain, the lower chain cloth is connected with the lower chain; the upper chain is connected with the upper chain seat, the lower chain is connected with the lower chain seat, the handle frame is fixedly connected with the upper chain seat, the upper chain seat is connected with the The chain seat is fixedly connected; or, the handle frame, the upper chain seat and the lower chain seat are made of an integral material; the upper chain seat and the lower chain seat are staggered from each other, the upper chain seat and the lower chain seat are not on the same vertical line, and the upper chain seat The distance between the center line and the lower center line of the lower chain seat is greater than zero; the upper chain and the lower chain are staggered from each other, and the upper chain and the lower chain are not on the same vertical line; when criminals insert sharp objects into the upper chain, they cannot be inserted into the lower chain at the same time On the top, prevent criminals from inserting sharp objects into the chain and cutting the chain.

The method of using the anti-theft double-layer zipper is: when in use, connect the two sides of the upper chain cloth and the lower chain cloth with the mouth of the suitcase, or connect the two sides of the upper chain cloth and the lower chain cloth with the pocket mouth of the luggage bag, and The handle of the chain seat is located outside the suitcase or the luggage bag; when the suitcase is closed, the handle on the chain seat pulls the chain seat to move, the upper chain seat moves with the handle to close the upper chain, and the lower chain seat moves with the upper chain seat To close the lower chain, use the upper chain and the lower chain to close, so that the upper closure after the upper chain is closed and the lower closure after the lower chain are closed are staggered from each other, so that the upper closure is located on the left side of the lower closure, or the upper closure is closed The opening is located on the right side of the lower closing opening, and the opening of the suitcase or the bag opening of the luggage bag is closed. To the lower closing port, to avoid criminals using sharp tools to open the zipper; when opening the mouth of the suitcase or the pocket of the luggage bag, use the hand to pull the chain seat to move in the opposite direction through the handle, and the chain seat moves with the handle to make the upper chain go up. The closing port is opened, and the lower chain seat moves with the upper chain seat so that the lower closing port of the lower chain is opened.

The beneficial effects of the present invention are: the anti-theft double-layer slide fastener is arranged on the luggage case or luggage bag, and the anti-theft double-layer slide fastener is provided with an upper chain and a lower chain; when the luggage case or luggage bag is hit, the upper chain and the lower chain disperse the The impact force of the mouth of the suitcase or the mouth of the luggage bag can avoid or reduce the cracking of the mouth of the suitcase or the mouth of the luggage bag, and improve the strength of the zipper; Improve the anti-theft performance of suitcases and luggage bags, so that criminals cannot use sharp tools to insert on the upper chain and lower chain at the same time, and increase the difficulty for criminals to use sharp tools to insert the zipper.
