[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] It should be noted that when a component is referred to as being "mounted on" another component, it may be mounted directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component. When a component is considered to be "fixed to" another component, it may be directly fixed to the other component or there may be a central component.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 and Figure 2 As shown, the nylon-edged zipper includes a tooth 1 made of metal material and a tooth head 2 made of nylon material. One end of the tooth 1 has a recessed positioning groove 1a, and the other end of the tooth 1 has a protruding connecting portion 1b. The inner end of the tooth head 2 has a recessed connecting recess 2a that matches the connecting portion 1b. The connecting portion 1b is embedded in the connecting recess 2a and the inner end of the tooth head 2 is in contact with the outer end surface of the tooth 1. There is also a positioning structure between the tooth head 2 and the tooth 1 that enables the two to be securely connected.

[0026] The teeth 1 and the tooth head 2 are made of different materials. The teeth 1 are made of metal, such as copper, aluminum, nickel, etc. The tooth head 2 is made of nylon plastic.

[0027] It can be seen that the teeth 1 and the tooth head 2 made of different materials can be stably connected together through the positioning structure. The metal teeth 1 ensure that the entire zipper has sufficient strength, and the nylon tooth head 2 is more wear-resistant and more beautiful.

[0028] The positioning structure includes a positioning hole 1b1 that passes through the connecting portion 1b transversely, and the inner end portion of the tooth head 2 is embedded in the positioning hole 1b1.

[0029] The tooth head 2 made of nylon plastic is formed at the outer end of the tooth 1 by injection molding.

[0030] After forming, the inner end of the tooth head 2 will be stably embedded in the positioning hole 1b1. This structure can ensure that the tooth head 2 and the tooth 1 are stably connected together.

[0031] The connecting portion 1b is in the shape of an elongated strip, and the number of the positioning holes 1b1 is several, and the positioning holes 1b1 are evenly distributed along the length direction of the connecting portion 1b.

[0032] The provision of multiple positioning holes 1b1 can further improve the connection stability between the tooth head 2 and the tooth 1.

[0033] The positioning structure further includes a second positioning hole 1c recessed at the upper end of the tooth 1, and the inner end portion of the tooth head 2 is embedded in the second positioning hole 1c.

[0034] Similarly, the tooth head 2 made of nylon plastic material will be partially embedded in the positioning hole 2 1c after injection molding, further improving the connection stability between the tooth head 2 and the tooth 1.

[0035] The positioning hole 1c is a blind hole.

[0036] This structure enables the nylon material to be stably embedded in the teeth during the injection molding process.

[0037] The depth of the second positioning hole 1c is 1 / 2 of the height of the tooth 1. Of course, according to actual conditions, it is also feasible that the depth of the second positioning hole 1c is 2 / 3 of the height of the tooth.

[0038] The width of the connecting portion 1b is 1 / 3 of the width of the tooth 1. According to actual conditions, the width of the connecting portion 1b can also be 1 / 2 of the width of the tooth 1.

[0039] Such a structure can appropriately increase the connection area between the inner end of the tooth head 2 and the outer end of the tooth 1.

[0040] The connecting portion 1b and the tooth 1 are an integrated structure.

[0041] The inner diameter of the second positioning hole 1c is larger than the inner diameter of the first positioning hole 1b1.

[0042] The inner diameter of the second positioning hole 1c is twice that of the first positioning hole 1b1. According to actual conditions, it is also feasible that the inner diameter of the second positioning hole 1c is three times that of the first positioning hole 1b1.

[0043] Since the nylon hemmed zipper is formed by combining the teeth of metal material and the tooth head of nylon material, the beauty and durability are improved while the strength is guaranteed, and the stability is relatively high.

[0044] At the same time, the tooth head is stably connected to the tooth under the action of the connecting structure. Therefore, its connection stability is relatively high, and the tooth head is stably connected to the outer end of the tooth. Its structure is relatively compact and has high practical value.

[0045] The various technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention.
