[0024] When in use, two waterproof cloths 3 are covered by the surface of the sprocket belt 15, one side of the two waterproof cloths 3 is respectively attached to the outside of the first zipper belt 1 and the second zipper belt 2, and the other side is tightly attached to the surface of the sprocket belt 15 and fixed by the zipper assembly, which not only enhances the waterproof performance of the zipper, but also further reduces the contact between the sprocket belt 15 and the external environment, thereby improving the sealing performance. The zipper assembly is slidably connected to the two zipper belts through the limiting groove 14, which can ensure the stability and accuracy of the zipper assembly during the sliding process and avoid the gap problem caused by the displacement or shaking of the zipper head 7.

[0025] A protrusion 6 is fixedly installed on the inner side of the top end of the first zipper tape 1 and the second zipper tape 2, and one side of the protrusion 6 is fixedly connected to the side wall of the limiting groove 14. When the zipper head 7 slides to the top end, the protrusion 6 will prevent the zipper head 7 from continuing to slide, thereby playing a limiting role and preventing the zipper head 7 from sliding out.

[0026] The zipper assembly also includes a first guide plate 4 and a second guide plate 11, one end of the zipper head 7 is fixedly mounted on the first guide plate 4, a fixing plate 12 is fixedly mounted between the first guide plate 4 and the second guide plate 11, the second guide plate 11 is fitted on the backs of the first zipper tape 1 and the second zipper tape 2, an anti-pinch assembly is provided on the outer walls of the first guide plate 4 and the second guide plate 11, the fixing plate 12 is located between the first guide plate 4 and the second guide plate 11, the structural strength of the entire zipper assembly is increased, the zipper is not easily deformed or damaged when subjected to external force, and its durability is improved, the second guide plate 11 is fitted on the backs of the first zipper tape 1 and the second zipper tape 2, which can effectively prevent the sprocket belt 15 from directly contacting clothing or other items, reduce wear and scratches, and help maintain the beauty and integrity of clothing.

[0027] The anti-pinch assembly includes a first anti-pinch block 9 and a second anti-pinch block 10. The first anti-pinch block 9 is fixedly mounted on the outer walls on both sides of the first guide plate 4, and the second anti-pinch block 10 is fixedly mounted on the outer walls on both sides of the second guide plate 11. The main functions of the first anti-pinch block 9 and the second anti-pinch block 10 are to prevent the zipper from pinching clothing, skin or other objects during sliding or closing.

[0028] The inner walls on both sides of the first guide plate 4 and the second guide plate 11 are provided with sprocket grooves 19, and the sprocket belt 15 is slidably connected inside the sprocket grooves 19. The design of the sprocket grooves 19 helps to ensure that the sprocket belt 15 can fit tightly when closed, reduce or eliminate possible gaps, improve the sealing of the zipper, prevent moisture, dust and other external impurities from entering the interior of the clothing, and protect the user's wearing experience.

[0029] The outer walls on both sides of the first guide plate 4 are fixedly mounted with a protruding plate 13, one end of which is limitedly connected to a limiting groove 14. The cooperation between the protruding plate 13 and the limiting groove 14 can ensure that the zipper assembly always maintains the correct track and position during the sliding process, which helps to reduce the shaking or deviation of the zipper and improve the accuracy and smoothness of sliding.

[0030] The two sides of the dense tail piece 5 are fixedly connected to the first zipper tape 1 and the second zipper tape 2, and a fixing block 16 is fixedly installed on the inner bottom end of the dense tail piece 5. A spring seat 17 is arranged on the top of the fixing block 16, and a buffer spring 18 is fixedly installed on the surface of the spring seat 17. The top of the buffer spring 18 is fit-connected with the bottom end of the sprocket belt 15. The spring seat 17 and the buffer spring 18 are arranged on the fixing block 16 at the inner bottom end of the dense tail piece 5. Such a design can provide a certain buffering effect when the zipper is closed. When the bottom end of the sprocket belt 15 contacts the fixing block 16, the buffer spring 18 can absorb the impact force, reduce the risk of damage to the sprocket belt 15, and enhance the smoothness when the zipper is closed.
