Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and in particular to a high-strength, lightweight zipper. Background Technology

[0002] Zippers are connectors that use continuously arranged teeth to join or separate items. They are now widely used in clothing, bags, tents, and other products, and are an essential part of daily life. Zippers bring a lot of convenience to people's lives and are one of the things people pay attention to in their daily lives. With the development of society, people also hope that zippers can be diversified in addition to their convenience.

[0003] However, the existing zipper teeth do not mesh firmly with the fabric tape, and teeth will fall out after long-term use. In addition, the zipper is not thin and soft overall, and the zipper will arch up a large part due to its lack of smoothness. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength, lightweight zipper that solves the problems of existing zippers easily losing teeth and zippers becoming stiff and arching.

[0005] To achieve the above objectives, a high-strength, lightweight zipper is provided, comprising: fabric tape, two fabric tapes, each fabric tape having teeth on its sidewalls, each tooth having a slot on its sidewall, a slot having an insertion hole in the center of the slot, an aluminum alloy component fixedly connected to the sidewall of the tooth, and multiple mounting holes in the center of each of the two fabric tapes, with metal pads provided on the outside of each mounting hole;

[0006] The fabric tape consists of a waterproof coating, a tensile layer, and a flexible layer.

[0007] According to the high-strength, lightweight zipper, one of the fabric sidewalls has a toothed groove, and the other fabric sidewall has a toothed block.

[0008] According to the high-strength, lightweight zipper described above, the tensile layer is disposed between two waterproof coatings.

[0009] According to the high-strength lightweight zipper, the tensile layer is made of high-strength polyester fiber, the waterproof coating is made of nano-coating, the metal pad material is aluminum alloy, and the flexible layer is made of carbon fiber reinforced POM.

[0010] According to the high-strength, lightweight zipper, one end of the fabric tape is provided with a lower stop member, and the other end of the fabric tape is provided with an upper stop member.

[0011] According to the high-strength, lightweight zipper, both the upper and lower stop members have fixing blocks on their side walls, and the middle part of the fixing block is fixedly connected to the outside of the fabric tape.

[0012] According to the high-strength, lightweight zipper, the upper stop and lower stop sidewalls cooperate with each other, a spring is provided inside the upper stop, a protrusion is fixedly connected to the upper end of the spring, and the upper end of the protrusion extends through the sidewall of the upper stop to the outside.

[0013] According to the high-strength, lightweight zipper, a zipper head is provided on the outside of the zipper teeth, and a handle is rotatably connected to the outside of the zipper head.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. This utility model utilizes an aluminum alloy component, a socket, a mounting hole, and a metal pad to work together. The aluminum alloy component can pass through the middle of the mounting hole, and the front end of the aluminum alloy component is bent to fit into the inside of the socket, thus fixing the chain teeth to the outside of the fabric tape. Furthermore, a metal pad is provided at the position where the aluminum alloy component wraps with the fabric tape, which can improve the strength of the connection between the chain teeth and the fabric tape and prevent them from falling off.

[0016] 2. This utility model provides a flexible layer, a waterproof coating, and a tensile layer in the middle of the fabric tape. The flexible layer ensures the flexibility of the fabric tape, the waterproof coating prevents water from penetrating the inside of the fabric tape, and the tensile layer increases the strength of the fabric tape and prevents breakage.

[0028] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0029] Reference Figure 1-7 This utility model embodiment discloses a high-strength, lightweight zipper, comprising: a fabric tape 1, two fabric tapes 1, each fabric tape 1 having a zipper tooth 8 on its side wall, a slot 14 on the side wall of the zipper tooth 8, an insertion hole 16 in the center of the slot 14, an aluminum alloy part 15 fixedly connected to the side wall of the zipper tooth 8, the aluminum alloy part 15 being bent to cooperate with the inside of the insertion hole 16 to fix the zipper head 8 to the outside of the fabric tape 1, and multiple mounting holes 6 in the center of each of the two fabric tapes 1, with metal pads 5 provided on the outside of the multiple mounting holes 6;

[0030] The fabric tape 1 is composed of a waterproof coating 2, a tensile layer 3 and a flexible layer 18, which not only ensures the flexibility of the fabric tape 1, but also improves the strength of the fabric tape 1.

[0031] One of the fabric tapes 1 has a toothed groove 12 on the side wall of the chain tooth 8, and the other fabric tape 1 has a toothed block 13 on the side wall of the chain tooth 8. The tensile layer 3 is placed between the two waterproof coatings 2. The tensile layer 3 is made of high-strength polyester fiber, which has better tear resistance than ordinary cotton tape. The waterproof coating 2 is a nano-coating, which is waterproof, UV resistant, and extends the service life. The metal pad 5 is made of aluminum alloy. The flexible layer 18 is made of carbon fiber reinforced POM. Polyoxymethylene (POM) mixed with 10%~20% carbon fiber increases the tensile strength by 80% and is 60% lighter than metal. One end of the fabric tape 1 is provided with a lower stop 7, and the other end of the fabric tape 1 is provided with an upper stop 10. Both the upper stop 10 and the lower stop 7 have fixing blocks 9 on their side walls. The middle part of the fixing block 9 is fixedly connected to the outside of the fabric tape 1. The side walls of the upper stop 10 and the lower stop 7 cooperate with each other. The upper stop 10 has a spring 17 inside. The elasticity of the spring 17 can push the protrusion 11 to move and can store the protrusion 11 for easy replacement of the zipper pull 4. The upper end of the spring 17 is fixedly connected to the protrusion 11. The upper end of the protrusion 11 extends to the outside through the side wall of the upper stop 10. The zipper pull 4 is provided outside the chain tooth 8. The zipper pull 4 moves outside the chain tooth 8 and opens and closes the zipper during the movement. The zipper pull 4 is rotatably connected to the outside of the zipper pull 4.

[0032] Working principle: One end of the aluminum alloy part 15 is passed through the middle of the mounting hole 6. By bending, the front end of the aluminum alloy part 15 is inserted into the interior of the insertion hole 16. The aluminum alloy part 15 wraps and squeezes the metal pad 5. During the squeezing, the chain teeth 8 will not break the fabric tape 1, thus preventing the chain teeth 8 from falling off. Furthermore, the waterproof coating 2, tensile layer 3, and flexible layer 18 work together to prevent the fabric tape 1 from arching up significantly due to lack of flexibility and to prevent the fabric tape 1 from breaking.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
