Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to an anti-falling hidden sewing zipper. Background Art

[0002] A zipper is a connector that connects or separates items by means of continuously arranged chain teeth. It is now widely used in clothing and bags, and the invisible sewing zipper is one of the zippers.

[0003] Some traditional invisible sewing zippers are composed of chain teeth, sliders and limit codes;

[0004] The existing hidden stitching zipper has the following problems, such as the pull head is easy to fall off when too much force is applied, and it is easy to be damaged and fall off during stitching. Therefore, we propose an anti-falling hidden stitching zipper. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide an anti-falling invisible sewing zipper, which is more secure to install and the pull head is not easy to fall off, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-dropping invisible sewing zipper, comprising a chain belt, chain teeth and a nylon installation cloth;

[0007] Chain belts: There are two of them, and the adjacent surfaces of the chain belts are fixedly connected with zipper cloths;

[0008] Chain teeth: They are all fixedly connected to the proximal ends of the zipper cloth, and the upper end of the outer surface of the whole composed of the chain teeth is slidably connected to the slider;

[0009] Nylon mounting cloth: It is fixedly connected to the opposite sides of the chain belt, making the installation more secure and not easy to fall off during use. At the same time, the pull head is less likely to fall off.

[0010] Furthermore, a pull ring is slidably connected inside the front end of the slider, which saves manpower.

[0011] Furthermore, the front and rear sides of the nylon installation cloth are fixedly connected with a nylon cloth wear-resistant layer, so the installation is more secure and more wear-resistant.

[0012] Furthermore, the front side surface of the whole composed of the nylon installation cloth and the nylon cloth wear-resistant layer is provided with evenly distributed installation holes, and the inside of the installation holes is fixedly connected with a connecting iron ring, so that the installation is more secure.

[0013] Furthermore, both the front and rear ends of the zipper cloth are fixedly connected with limit nut, and the limit nut is installed in cooperation with the slider to play a limiting role.

[0014] Furthermore, the opposite ends of the limiter are fixedly connected to the limit block to prevent falling off.

[0015] Furthermore, the chain teeth are arranged in a staggered manner so that the chain teeth can mesh with each other.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the anti-falling invisible sewing zipper has the following advantages:

[0017] 1. When the slider slides to both ends on the outer surface of the whole composed of the chain teeth, the slider slides onto the limit block, and the support frame at the middle end of the slider contacts the limit block. The two limit blocks lock the slider, thereby preventing the slider from falling off due to excessive force when in use.

[0018] 2. During installation, sew the whole composed of nylon installation cloth and nylon cloth wear-resistant layer into the entrance of clothing and luggage, and then sew it by passing the nylon thread into the inside of the connecting iron ring, so that the installation is more secure. And because the materials of nylon installation cloth and nylon cloth wear-resistant layer are more wear-resistant and the fabric strength is higher, it is more secure than ordinary sewing installation and is not easy to fall off.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4, this embodiment provides a technical solution: an anti-falling hidden sewing zipper, including a chain belt 1, chain teeth 3 and a nylon installation cloth 6;

[0026] Chain belts 1: There are two of them. The adjacent surfaces of the chain belts 1 are fixedly connected with zipper cloths 2. The front and rear ends of the zipper cloths 2 are fixedly connected with limit stoppers 10. The limit stoppers 10 are installed in coordination with the slider 4. The opposite ends of the limit stoppers 10 are fixedly connected with limit blocks 11.

[0027] Chain teeth 3: They are all fixedly connected to the proximal ends of the zipper cloth 2. The upper end of the outer surface of the whole composed of the chain teeth 3 is slidably connected with a pull head 4, and the front end of the pull head 4 is slidably connected with a pull ring 5. The chain teeth 3 are staggered with each other. When the pull head 4 slides to both ends on the outer surface of the whole composed of the chain teeth 3, the pull head 4 slides onto the limit Ma 10, and the support frame at the middle end of the pull head 4 contacts the limit block 11. The two limit blocks 11 play a locking role on the pull head 4, thereby preventing the pull head 4 from falling off when using it with excessive force;

[0028] Nylon mounting cloth 6: It is fixedly connected to the opposite sides of the chain belt 1, and the front and rear sides of the nylon mounting cloth 6 are fixedly connected with the nylon cloth wear-resistant layer 7. The front side of the whole composed of the nylon mounting cloth 6 and the nylon cloth wear-resistant layer 7 is provided with evenly distributed mounting holes 8, and the inside of the mounting holes 8 is fixedly connected with a connecting iron ring 9. During installation, the whole composed of the nylon mounting cloth 6 and the nylon cloth wear-resistant layer 7 is sewn into the entrance of clothing and bags, and then the nylon thread is inserted into the inside of the connecting iron ring 9 for sewing, so that the installation is more secure. In addition, since the materials of the nylon mounting cloth 6 and the nylon cloth wear-resistant layer 7 are more wear-resistant and the fabric strength is higher, it is more secure than ordinary sewing installation and is not easy to fall off.

[0029] The working principle of the anti-falling hidden sewing zipper provided by the utility model is as follows: when the slider 4 slides to both ends on the outer surface of the whole composed of the chain teeth 3, the slider 4 slides onto the limit blocks 10, and the supporting frame at the middle end inside the slider 4 contacts the limit blocks 11. The two limit blocks 11 lock the slider 4, thereby preventing the slider 4 from falling off when using excessive force. During installation, the whole composed of the nylon installation cloth 6 and the nylon cloth wear-resistant layer 7 is sewn into the entrance of clothing and bags, and then the nylon thread is inserted into the inside of the connecting iron ring 9 for sewing, so that the installation is more secure. Moreover, since the materials of the nylon installation cloth 6 and the nylon cloth wear-resistant layer 7 are more wear-resistant and the fabric strength is higher, the installation is more secure than ordinary thread sewing and is not easy to fall off.

[0030] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
