Zipper with waterproof layer

Abstract

The invention discloses a zipper with the self-formed waterproof layer and belongs to the field of zippers, and is characterized in that outer variable magnetic bags are arranged at lower end parts of zipper teeth, when the zipper teeth are zipped, the outer variable magnetic bags deform under the action of extrusion force of an inner bottom surface of a zipper head, and inner bottom ends of the outer variable magnetic bags are gradually close to lower end parts of the zipper teeth in the longitudinal direction and are absorbed and fixed with the lower end parts of the zipper teeth; outer variable magnetic bags transversely deform outwards and gradually get close to the adjacent zipper teeth, outer ends of every two adjacent outer variable magnetic bags are attracted with each other in cooperation with the attraction force of the side attraction hemispheres, and therefore a waterproof layer is formed between the multiple zipper teeth after zipper combination, and a problem that in the prior art, due to the fact that a gap exists between every two zipper teeth, the waterproof performance is poor is effectively solved; and meanwhile, the air powder body is matched, so a user can be effectively reminded of the condition that the outer variable magnetic bag is accidentally broken, and the certain lubricating and maintaining effect can be achieved on the adjacent zipper teeth.

Description

technical field [0001] The invention relates to the field of slide fasteners, in particular to a slide fastener with a self-contained waterproof layer. Background technique [0002] Zipper is a connecting piece that relies on continuous arrangement of chain teeth to make items merge or separate. It is now widely used in clothing, bags, tents, etc. The zipper is composed of chain teeth, sliders, upper and lower stops (front code and rear code) or locking pieces. Among them, the sprocket is a key part, which directly determines the side pulling strength of the zipper. Generally, the zipper has two chain belts, each of which has a row of chain teeth, and the two rows of chain teeth are arranged alternately. The slider clamps the chain teeth on both sides, and the chain teeth on both sides can be meshed or disengaged by sliding with the help of the pull tab. [0003] The conventional zipper usually includes two pieces of cloth zipper pieces, respectively combined with the cha...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a zipper with a self-contained waterproof layer, which is provided with an external variable magnetic bag at the lower end of the chain tooth. When the chain is closed, the external variable magnetic bag is inside the slider Under the action of the extrusion force on the bottom surface, the inner bottom end of the outer variable magnetic capsule gradually approaches the lower end of the sprocket in the longitudinal direction and is fixed by adsorption, so that the lateral shape of the external variable magnetic capsule changes and gradually approaches the adjacent sprocket, and cooperates with the side suction hemisphere The adsorption force makes the outer ends of the adjacent two external variable magnetic capsules adsorb each other, so that a waterproof layer is formed between the chain teeth after chaining, and then effectively compensates for the existence of existing gaps between the two chain teeth in the prior art. The gap leads to poor waterproof performance, which effectively protects the items in the closed space of the zipper from being affected by moisture. At the same time, with the use of air powder, it can not only effectively remind the user of the accidental rupture of the magnetic bag of the external changer, but also protect the adjacent chain teeth. Play a certain lubrication maintenance effect
