Description

Technical Field

[0001] The invention belongs to the technical field of zippers, and in particular relates to a high-air-tightness zipper. Background Art

[0002] The core of high airtightness zipper design is to ensure that it can effectively prevent the penetration of substances such as gas and moisture even in extreme environments.

[0003] According to the public disclosure of a high-airtightness zipper for a jacket, publication number: CN219781757U, it includes two pieces of chain cloth connected with chain teeth, and a puller for engaging or separating the two chain teeth is slidably provided at the two chain teeth, and a pull tab is connected to the puller; the front of the chain cloth is connected to a windproof cloth, and one side of the windproof cloth extends from the side of the chain cloth and completely covers the chain teeth; a soft magnetic strip is connected to the side position of the extended part of the windproof cloth. When the zipper is in use, some users need to pull the zipper to a suitable position, such as high-performance outdoor equipment or special-purpose protective clothing, and ensure that this position is maintained during use. This is very necessary in occasions that require precise operation. Through the mutual cooperation between the above-mentioned chain teeth, pullers and other components, it is difficult to allow the user to adjust the zipper to a very precise position and ensure that this position is maintained during use, which needs to be improved.

Through the mutual cooperation between the moving plate, hinge block, long rod, rotating shaft and other components inside the position fixing device, the long rod, moving plate, hinge block, handle and other components can be temporarily fixed in a suitable position for convenience of users. The fixing mechanism allows the user to adjust the zipper to a very precise position and ensure that this position is maintained during use. This is very useful in situations where precise operation is required and solves the existing problems.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a high-air-tightness zipper, comprising a zipper track, a side surface of the zipper track is provided with zipper teeth, a side surface of the zipper track is provided with a position fixing structure, the position fixing structure comprises a movable plate, the movable plate is arranged on the side surface of the zipper teeth, a hinge block is fixedly connected to the side surface of the movable plate, a handle is rotatably connected to the inner wall of the hinge block, the top of the handle is rotatably connected to a rotating shaft, a long rod is fixedly connected to the circumferential surface of the rotating shaft, a telescopic rod is fixedly connected to the end of the long rod away from the rotating shaft, a slide groove is provided on the side surface of the zipper track, a fixed plate is fixedly connected to the inner wall of the slide groove, and a limiting groove is provided on the top of the fixed plate.

[0007] Furthermore, the limit groove is located on the displacement track of the telescopic rod, the long rod and the handle are set to metal material, and a hinge is set on the inner wall of the zipper track. The hinge operates the closing and opening of the zipper, and the design usually takes into account the sealing performance to maintain air tightness.

[0008] Furthermore, there are two slide grooves, which are symmetrical to each other along the vertical center axis of the zipper track. The slide grooves are located on the sides of the zipper teeth, and are designed to accommodate the fixing plate.

[0009] Furthermore, a plurality of the fixed plates are provided along a linear array on the inner wall of the slideway, and the movable plate is provided with a metal material, which is relatively hard, not easily damaged, and can be used for a long time.

[0010] Furthermore, a protective layer assembly is provided on the inner wall of the zipper track, and the protective layer assembly includes a sealing layer, and the sealing layer is provided on the inner wall of the zipper track, and a zipper tape layer is provided below the sealing layer. The precise design and material selection of these layers are the key to ensuring that the high-airtightness zipper can maintain functionality in various harsh environments.

[0011] Furthermore, the sealing layer is located between the zipper track and the sealing layer, and the sealing layer prevents the penetration of gas and liquid, thereby ensuring the air tightness and waterproofness of the zipper.

[0012] Furthermore, an inner lining layer is provided below the zipper tape layer, serving as a main structural part of the zipper to provide basic support and strength.

[0013] Furthermore, the interior of the sealing layer includes rubber, silicone, and thermoplastic polyurethane, which is conducive to better sealing.

[0014] Furthermore, the zipper tape layer and the lining layer are both arranged on the inner wall of the zipper track.

[0015] Furthermore, the zipper tape layer is located between the sealing layer and the lining layer, and the interior of the zipper tape layer includes polyester fiber and nylon.

[0016] The present invention has the following beneficial effects:

[0017] 1. The present invention realizes that the long rod, moving plate, hinge block, handle and other components can be temporarily fixed in a suitable position through the mutual cooperation between the moving plate, hinge block, long rod, rotating shaft and other components inside the position fixing device, which is convenient for users to use. The fixing mechanism allows the user to adjust the zipper to a very precise position and ensure that this position is maintained during use, which is very useful in situations requiring precise operation.

[0018] 2. The present invention prevents the penetration of gas and liquid through the rubber, silicone and thermoplastic polyurethane inside the sealing layer and ensures the air tightness and waterproofness of the zipper through the mutual cooperation between the sealing layer, the inner lining layer, the zipper tape layer and other components inside the protective layer component. The zipper tape layer can provide basic support and strength to the zipper through the internal polyester fiber and nylon. The interior of the inner lining layer includes wear-resistant materials, which can provide additional support and stability and enhance the sealing effect. The precise design and material selection of these layers are the key to ensuring that the high-air-tightness zipper can maintain functionality in various harsh environments.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
