Description

Technical Field

[0001] This utility model relates to the field of zipper technology, specifically a waterproof nylon zipper with a protective structure. Background Technology

[0002] In the field of zipper technology, nylon zippers are widely used in clothing, bags, and outdoor products due to their smooth opening and closing and moderate cost. However, existing nylon zippers have significant shortcomings in use: Firstly, their waterproof performance is poor, with most products lacking a dedicated sealing and protective structure, allowing water to easily penetrate through the gaps in the zipper teeth or the surface of the zipper tape, making them unsuitable for outdoor and water-related applications requiring waterproofing. Secondly, their protective capabilities are weak, with the zipper tape and teeth directly exposed, making them susceptible to damage from daily wear and tear, external stretching and compression, resulting in a shortened zipper lifespan and failing to meet users' higher demands for durability and protection.

[0003] To address this issue, we propose a waterproof nylon zipper with a protective structure. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof nylon zipper with a protective structure, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof nylon zipper with a protective structure, comprising:

[0006] Zipper head;

[0007] The first zipper tape and the second zipper tape are respectively located on both sides of the zipper head;

[0008] The first zipper tooth and the second zipper tooth are respectively fixed on the opposite edges of the first zipper tape and the second zipper tape, and are used to cooperate with the zipper head to realize the opening and closing of the zipper;

[0009] A protective strip covers the outer surface of the first zipper tape and the second zipper tape and is fixedly connected to the first zipper tape and the second zipper tape to provide additional protection;

[0010] The protective fabric strip includes at least a multi-layer structure consisting of a rubber body, a base material, an intermediate layer, and a surface layer;

[0011] The two protective fabric strips are positioned so that their ends are in contact with each other.

[0012] Preferably, the rubber body is located in the innermost layer of the protective fabric strip, directly contacting the first zipper tape and the second zipper tape, providing waterproof and sealing functions.

[0013] Preferably, the substrate is located on the rubber body, and the substrate is made of high-density polyethylene fabric.

[0014] Preferably, the intermediate layer is located on the substrate, and the intermediate layer is made of polyurethane.

[0015] Preferably, the surface layer is located on the outermost layer of the protective fabric strip, and the surface layer is made of polytetrafluoroethylene microporous membrane.

[0016] Preferably, the first and second chain teeth are made of nylon, which allows the zipper to open and close smoothly when used with the zipper head.

[0017] Preferably, the protective fabric strip is fixed to the outer surface of the first zipper tape and the second zipper tape by sewing, heat melting or adhesive bonding.

[0018] This invention provides a waterproof nylon zipper with a protective structure. This waterproof nylon zipper with a protective structure has the following advantages:

[0019] (1) The waterproof nylon zipper with protective structure has the following waterproof effect: the innermost rubber body of the protective strip is in direct contact with the zipper tape, which can provide basic waterproof and sealing functions; the two protective strip ends are in contact with each other to further optimize the sealing performance, and the nylon teeth and zipper head work together smoothly to reduce the risk of water entering the gap during opening and closing, thus achieving overall waterproofing of the zipper.

[0020] (2) The waterproof nylon zipper with protective structure has the following protective effect: the protective strip covering the outside of the zipper tape has a multi-layer structure that works together to provide protection. The high-density polyethylene fabric substrate enhances the structural stability, the polyurethane material middle layer improves the toughness to resist stretching and extrusion, and the polytetrafluoroethylene microporous membrane surface layer resists external wear and stains. It protects the zipper tape and teeth as a whole and extends the service life of the zipper. Attached Figure Description

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a waterproof nylon zipper with a protective structure, comprising:

[0028] Zipper head 1;

[0029] The first zipper tape 2 and the second zipper tape 4 are respectively located on both sides of the zipper head 1;

[0030] The first zipper tooth 3 and the second zipper tooth 5 are respectively fixed on the opposite edges of the first zipper tape 2 and the second zipper tape 4, and are used to cooperate with the zipper head 1 to realize the opening and closing of the zipper. The first zipper tooth 3 and the second zipper tooth 5 are made of nylon and can smoothly open and close the zipper when they cooperate with the zipper head 1.

[0031] A protective strip 6 covers the outer surface of the first zipper tape 2 and the second zipper tape 4 and is fixedly connected to the first zipper tape 2 and the second zipper tape 4 to provide additional protection.

[0032] The protective fabric strip 6 includes at least a multi-layer structure consisting of a rubber body 7, a base material 8, an intermediate layer 9, and a surface layer 10. The rubber body 7 is located in the innermost layer of the protective fabric strip 6 and is in direct contact with the first zipper tape 2 and the second zipper tape 4, providing waterproof and sealing functions. The base material 8 is located on top of the rubber body 7 and is made of high-density polyethylene fabric. The intermediate layer 9 is located on top of the base material 8 and is made of polyurethane. The surface layer 10 is located in the outermost layer of the protective fabric strip 6 and is made of polytetrafluoroethylene microporous membrane.

[0033] The two protective fabric strips 6 are arranged with their end faces in contact with each other, and the protective fabric strips 6 are fixed to the outer surfaces of the first zipper tape 2 and the second zipper tape 4 by sewing, heat melting or adhesive.

[0034] When in use, the waterproof nylon zipper with a protective structure engages or disengages with the first zipper tooth 3 and the second zipper tooth 5, which are respectively fixed to the opposite edges of the first zipper tape 2 and the second zipper tape 4, thus opening and closing the zipper. Simultaneously, a protective fabric strip 6, covering the outside of the first zipper tape 2 and the second zipper tape 4 and fixed by sewing, heat melting, or adhesive, provides protection. In its multi-layered structure, the innermost rubber body 7 directly contacts the zipper tape to provide a waterproof seal; the high-density polyethylene fabric substrate 8 above the rubber body 7 enhances structural stability; the polyurethane intermediate layer 9 above the substrate 8 improves toughness; and the outermost polytetrafluoroethylene microporous membrane surface layer 10 strengthens external protection. Furthermore, the end faces of the two protective fabric strips 6 contact each other, further optimizing the sealing and protective effects, ultimately achieving the waterproof and protective functions of the zipper.

[0035] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
