DETAILED DESCRIPTION

[0028] The following is a combination of the appended examples of the present invention Figure 1-5 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] Example:

[0030] like Figures 1 to 5 As shown, a high-strength nylon zipper includes bilaterally symmetrical PVC tapes 11, with sprockets 12 sewn on the opposite sides of the two PVC tapes 11, and small tapes 16 sewn between the sprockets 12 and the back sides of the PVC tapes 11 to strengthen the connection strength between the sprockets 12 and the PVC tapes 11. Through the above structure, the sprockets 12 are prevented from being torn when the user pulls the zipper vigorously, thereby increasing the overall strength of the zipper.

[0031] A zipper head 14 is connected to the sprocket 12, and a drawstring 15 is provided on the zipper head 14. The connection between the drawstring 15 and the zipper head 14 is as follows: a rotating shaft 19 is threadedly connected to the zipper head 14, and a ring groove 20 is provided on the rotating shaft 19. A rotating ring 21 is rotatably connected in the ring groove 20, and the drawstring 15 is fixedly connected to the rotating ring 21. If the drawstring 15 is damaged, the user can disassemble and replace the drawstring 15 by rotating the rotating shaft 19, which is easy to operate.

[0032] In order to facilitate the user to rotate the rotating shaft 19, the upper end of the rotating shaft 19 is fixedly connected to a rotating head 22, and a gripping notch 23 is provided on the rotating head 22. The above structure facilitates the user to grip the rotating head 22 to loosen the rotating shaft 19, making the operation of replacing the drawstring 15 more convenient.

[0033] A dust cover 13 is fixedly connected to the PVC cloth tape 11 on one side, and also includes a fixing mechanism for fixing the dust cover 13. The specific structure of the fixing mechanism is: the fixing mechanism includes a first rubber strip 17, and the first rubber strip 17 is fixed on the PVC cloth tape 11 on one side. A second rubber strip 18 is fixedly connected to the inner side surface of the dust cover 13, and the second rubber strip 18 is adhered to the first rubber strip 17.

[0034] After the user zips up the zipper, the user flips the dust cover 13 and covers the sprocket 12, and then aligns the second rubber strip 18 with the first rubber strip 17 so that the two fit together, thereby protecting the sprocket 12 and preventing dust, fibers or other small objects from entering the sprocket 12 and causing wear of the sprocket 12, thereby extending the service life of the sprocket 12.

[0035] In addition, a hydrophobic layer is provided on the outer surface of the dust cover 13. When the dust cover 13 covers the sprocket 12, it can play a certain waterproof role and prevent rainwater from passing through the sprocket 12 and wetting the items to be protected.

[0036] like Figure 2 as well as Figure 3 As shown, the dust cover 13 is provided with a positioning component for fixing the drawstring 15. The specific structure of the positioning component is: the positioning component includes an elastic clip 24, the number of the elastic clips 24 is two, and the elastic clips 24 are symmetrically arranged on the outer surface of the dust cover 13. A through slot 25 for the drawstring 15 to pass through is provided between the two elastic clips 24.

[0037] After the user zips up the zipper, the drawstring 15 is rotated and the end of the drawstring 15 passes through the through slot 25 , and the drawstring 15 is fixed to the dust cover 13 through the elastic clip 24 , thereby preventing the dust cover 13 from being hooked and torn by other objects during movement.

[0038] It should be noted here that the drawstring 15 is made of polyester. As a chemical fiber fabric, polyester has a stiffer texture compared to other chemical fiber fabrics such as acrylic, thereby ensuring that the drawstring 15 will not easily fall out of the through slot 25 after being inserted into the two elastic clips 24.

[0039] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
