Abstract
Description
Technical Field
[0001] This utility model relates to the field of zipper technology, and in particular to an explosion-proof nylon zipper. Background Technology
[0002] A zipper is a connector that uses continuously arranged teeth to join or separate soft, thin items, such as chain straps.
[0003] Zippers include nylon zippers. The chain strap in a nylon zipper is composed of nylon monofilaments wound around a central thread after being heated and pressed. Nylon is a common polymer with good wear resistance, flexibility and corrosion resistance. However, it is essentially a common synthetic material that is prone to sudden bursting when subjected to large tensile or compressive forces, making it easily damaged. Therefore, existing nylon zippers need to be improved to enhance their explosion-proof performance. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an explosion-proof nylon zipper to solve the problem of breakage in existing nylon zippers.
[0005] This utility model provides the following technical solution: an explosion-proof nylon zipper, including a left chain belt and a right chain belt, wherein chain teeth are respectively provided on both sides of the left chain belt and the right chain belt, and further including a zipper head for connecting each of the chain teeth;
[0006] Fabric tape is sewn onto the chain teeth located on one side of the left and right chain belts to form a four-layer structure. The fabric tape extends along the extension direction of the chain teeth and the length of the fabric tape is adapted to the length of the chain teeth.
[0007] Preferably, the fabric tape is mounted on the upper side of the chain teeth located on the upper side of the left and right chain tapes, and the fabric tape is fixed to the chain teeth located on the lower side of the left and right chain tapes by a cord.
[0008] Preferably, the cord passes through the left chain and the right chain.
[0009] Preferably, the chain teeth are nylon chain teeth.
[0010] Preferably, a center line is provided inside the chain teeth.
[0011] Preferably, the center line has no fewer than 4 strands.
[0012] Preferably, the fabric strip has multiple through slots spaced apart and arranged horizontally, and the cord is wound around the through slots to tightly bind the fabric strip.
[0013] This utility model provides an explosion-proof nylon zipper, which has the following beneficial effects:
[0014] This invention increases the explosion-proof capability of the chain by setting a cloth strip on the chain teeth. Furthermore, the cloth strip is sewn to another chain tooth with a rope to increase the connection strength between the two chain teeth and the chain. This further improves the strength and explosion-proof capability of the invention while simplifying the chain manufacturing process.
[0015] The chain teeth in this invention are made of nylon and have multiple center lines inside, which further increases durability. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0025] Reference Figures 1-3 According to an embodiment of the present invention, an explosion-proof nylon zipper includes a left chain belt 11 and a right chain belt 12. Both sides of the left chain belt 11 and the right chain belt 12 are respectively provided with chain teeth 13 to form a double-layer chain tooth zipper. It also includes a zipper head (not shown in the figure) for connecting each of the chain teeth 13.
[0026] In order to improve the explosion-proof and breakage-proof capability of the explosion-proof nylon zipper, a fabric tape 15 is sewn onto the chain teeth 13 located on one side of the left chain belt 11 and the right chain belt 12 to form a four-layer structure, specifically from top to bottom: fabric tape layer, chain tooth layer, chain belt layer, and chain tooth layer.
[0027] The fabric tape 15 extends along the extension direction of the chain tooth 13, and the length of the fabric tape 15 is adapted to that of the chain tooth 13.
[0028] Furthermore, the fabric tape 15 is sewn in such a way that it is attached to the upper side of the chain teeth 13 located on the upper side of the left chain tape 11 and the right chain tape 12, and the fabric tape 15 is fixed to the chain teeth 13 located on the lower side of the left chain tape 11 and the right chain tape 12 by a cord 17. That is, the upper and lower chain teeth 13 are sewn together by the cord 17, and the cord 17 passes through the left chain tape 11 and the right chain tape 12 to connect the fabric tape 15, the chain teeth 13, and the left chain tape 11 and the right chain tape 12.
