A self-contained waterproof zipper

Abstract

The invention discloses a zipper with a self-formed waterproof layer, belonging to the field of zippers. The invention discloses a zipper with a self-formed waterproof layer. By arranging an externally variable magnetic pocket at the lower end of the chain teeth, when the chain is closed, the externally variable magnetic pocket is placed on the zipper head. The inner bottom surface is deformed under the action of the extrusion force, and the inner bottom end of the outer changing magnetic capsule gradually approaches the lower end of the sprocket in the longitudinal direction and is fixed by adsorption, so that the outer changing magnetic capsule is laterally deformed and gradually approaches the adjacent sprockets. The adsorption force of the hemisphere makes the outer ends of the two adjacent externally variable magnetic capsules adsorb each other, so that a waterproof layer is formed between the plurality of chain teeth after the chain is combined, thereby effectively making up for the existing technology due to the gap between the two chain teeth. There is a problem of poor waterproofness caused by gaps, which effectively protects the items in the closed space of the zipper from being damp. At the same time, with the gas powder, it can not only effectively remind the user of the accidental rupture of the externally variable magnetic bag, but also effectively protect the adjacent chain. The teeth play a certain lubricating and maintenance effect.

Description

technical field [0001] The present invention relates to the field of zippers, and more particularly, to a zipper with a self-contained waterproof layer. Background technique [0002] Zipper (zipper) is a connecting piece that relies on continuously arranged sprockets to combine or separate items, and is now widely used in clothing, bags, tents, etc. The zipper is composed of chain teeth, sliders, upper and lower stops (front and rear) or locking pieces. The chain teeth are the key part, which directly determine the side pull strength of the zipper. Generally, the zipper has two pieces of chain belt, each chain belt has a row of sprockets, and the two rows of sprockets are arranged in a staggered manner. The sliders clamp the sprockets on both sides, and the sprockets on both sides can be engaged or disengaged by sliding with the help of the pull tab. [0003] The conventional zipper usually includes two pieces of cloth zipper piece, the chain teeth are respectively combin...

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
