The guide closure component is used to straighten the chain on both sides, thereby aligning the chain and facilitating the pulling of the chain head later. This makes the zipper run more smoothly. At the same time, the round-head teeth are the core component of the zipper. The round tooth structure facilitates the meshing of the teeth on both sides. The round tooth edges have no sharp corners or burrs. During the opening and closing of the zipper, the friction between the chain teeth and between the chain teeth and the zipper head is smoother, reducing mutual friction damage. The round shape The rounded teeth distribute the force more evenly when subjected to tension and friction, avoiding excessive wear caused by localized stress concentration and preventing tooth damage. This ensures the integrity and stability of the overall zipper structure. When the rounded teeth are in good condition, the zipper tail is equipped with a guide closure component. The corrective silicone strips on both sides close the rubber guide rails on both sides, and the spring tension corrects the position. This reduces the likelihood of problems such as zipper pull detachment and chain tearing, thereby extending the zipper's service life and reducing the frequency of zipper replacement or repair due to damage.

[0014] (2) Rubber guide rails are used to protect the outside of the toothed rack, reducing the accumulation of dust and debris on the round teeth, protecting the zipper closure, and making the zipper close tightly. Rubber guide rails can enhance the overall structural strength of the zipper, making it less prone to deformation when subjected to greater tension or pressure. They effectively block rainwater, dust and other external pollutants from entering the contents, protecting the contents from moisture and contamination. Rubber guide rails are soft and elastic, which can buffer the impact and friction of the zipper during opening and closing, reduce the wear rate of the round teeth and other parts, and extend the service life of the zipper.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] A zipper designed to prevent damage to the teeth includes a chain 1, a rubber guide rail 2 fixedly connected to one end of the chain 1, a filling and sewing foot 3 fixedly connected to the outer wall of the rubber guide rail 2, a sewing hole 4 provided on the outer wall of the filling and sewing foot 3, a chain head 5 meshingly connected to the inner side of the chain 1, a zipper 6 installed through the outer wall of the chain head 5, a guide closure component 7 provided at the bottom of the chain head 5, and round-headed teeth 8 provided on the inner side of the chain 1.

[0025] The above structure protects the round-head teeth 8 through the rubber guide rail 2 designed on the outside of the chain 1, and uses the guide closure component 7 to straighten the two sides of the chain 1, thereby aligning the chain 1 and facilitating the pulling of the chain head 5 later. This makes the zipper run more smoothly. At the same time, the round-head teeth 8 are the core component of the zipper. The round tooth structure facilitates the interlocking of the teeth on both sides.

[0026] Furthermore, the chain 1 is located between the rubber guide rails 2, and the rubber guide rails 2 wrap around the upper and lower sides of the chain 1, and the internal groove of the chain head 5 engages with the chain 1 and the rubber guide rails 2.

[0027] The above structure uses rubber guide rail 2 to protect the outside of the toothed rack, reducing the accumulation of dust and debris on the round-headed teeth 8, protecting the zipper closure, and making the zipper close tightly. Rubber guide rail 2 can enhance the overall structural strength of the zipper, making it less prone to deformation when subjected to greater tension or pressure, and effectively blocking rainwater, dust and other external pollutants from entering the inside of the item.

[0028] Furthermore, the suture holes 4 are arranged in a straight line on the suture foot 3, and the suture foot 3 is symmetrical to each other along the chain 1.

[0029] The above structure allows the filling suture foot 3 to be sewn to the place where a zipper is needed through the suture hole 4.

[0030] Furthermore, the chain 1 is provided in two sets, and the chains 1 on both sides are engaged with each other by round-headed teeth 8.

[0031] The above structure, with its rounded shape, ensures that the teeth are subjected to more even stress when subjected to tension and friction, avoiding excessive wear caused by localized stress concentration and preventing tooth damage.

[0032] Furthermore, the guide closure assembly 7 includes an inner chamber 701, a corrective silicone strip 702, a slider 703, and a spring 704. The bottom of the chain head 5 is fixedly connected to the inner chamber 701. The slider 703 is slidably installed inside the inner chamber 701. The top of the slider 703 is fixedly connected to the corrective silicone strip 702. The inner wall of the slider 703 is fixedly connected to the spring 704. The inner wall of the inner chamber 701 has a groove, and the slider 703 slides linearly along the groove. The inner side of the slider 703 is connected to the other side of the slider 703 through the spring 704. The bottom of the rubber guide rail 2 has a corrective groove, and the corrective silicone strip 702 slides along the corrective groove.

[0033] The above structure uses the guide closing component 7 to close the rubber guide rails 2 on both sides using the corrective silicone strips 702 on both sides, and uses the tension of the spring 704 to correct the position.

[0034] Working principle: In use, firstly, the round-head teeth 8 are protected by the rubber guide rail 2 designed on the outside of the chain 1. The guide closing component 7 is used to straighten the two sides of the chain 1, thereby aligning the chain 1 and facilitating the pulling of the chain head 5 later. This makes the zipper run more smoothly. At the same time, the round-head teeth 8 are the core component of the zipper. The round tooth structure facilitates the interlocking of the teeth on both sides. The round tooth edges have no sharp corners or burrs. During the opening and closing of the zipper, the friction between the chain teeth and between the chain teeth and the zipper head is smoother, reducing mutual friction damage. The round shape makes the teeth more evenly stressed when bearing tension and friction, avoiding excessive wear caused by local stress concentration, preventing tooth damage, and ensuring the integrity and stability of the overall zipper structure. When the round-head teeth 8 are in good condition;

[0035] Secondly, the zipper tail is equipped with a guide closing component 7, which uses the corrective silicone strips 702 on both sides to close the rubber guide rails 2 on both sides, and uses the pulling force of the spring 704 to correct the position, making it less likely to have problems such as the zipper head falling off or the chain tearing, thereby extending the service life of the zipper and reducing the frequency of zipper replacement or repair due to damage.

[0036] Finally, the rubber guide rail 2 protects the outside of the toothed rack, reducing the accumulation of dust and debris on the round-head teeth 8, protecting the zipper's closure, and ensuring a tight closure. The rubber guide rail 2 enhances the overall structural strength of the zipper, making it less prone to deformation when subjected to greater tension or pressure. It effectively prevents rainwater, dust, and other external pollutants from entering the contents, protecting them from moisture and contamination. The rubber guide rail 2 is soft and elastic, which can buffer the impact and friction during the opening and closing process of the zipper, reducing the wear rate of the round-head teeth 8 and other components, and extending the zipper's service life.
