Technical Field

[0001] The utility model relates to the technical field of zippers, and more specifically, to a waterproof zipper. Background Art

[0002] Zippers can connect various items through the design of chain teeth and pull heads. They play an important role in clothing, bags, tents and other fields, providing reliable closure and stability for items. Whether in daily wear or in outdoor activities, zippers ensure the safety and integrity of items with their excellent performance and durability.

[0003] In some special equipment, such as cold-proof clothing, tents and jackets, the waterproof performance of zippers is too high. When using traditional zippers, rainwater and water vapor can easily penetrate into the interior of the items through the connecting gaps of the zippers, causing damage. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a waterproof zipper. The technical problem to be solved by the present invention is that the conventional zipper has poor waterproof performance.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waterproof zipper, comprising two chain belts that cooperate with each other, the tops of the two chain belts are fixedly connected with waterproof cloth strips, the top of one of the waterproof cloth strips is fixedly connected with a concave strip, and the top of the other waterproof cloth strip is fixedly connected with a convex strip, and the concave strips and the convex strips cooperate with each other, and pull heads are installed on the outside of the two chain belts, the tops of the pull heads are fixedly connected with an opening and closing seat, and the concave strips and the convex strips are both located inside the opening and closing seat.

[0006] like Figure 1-3 As shown, the specific implementation method is: the waterproof cloth strip can play a role of water isolation, and the two chain belts can be meshed by pulling the slider. At the same time, the opening and closing seat can be driven to move, so that the convex strip can be embedded in the concave strip, thereby preventing water from penetrating from the joint of the two waterproof cloth strips, thereby improving the sealing of the zipper.

[0007] In a preferred embodiment, the concave strips and the convex strips are both rubber strips, the convex strips are in an I-shape, and the convex strips are embedded in the concave strips.

[0008] The sealing performance of the zipper can be enhanced by embedding the I-shaped convex strips into the concave strips.

[0009] In a preferred embodiment, a Velcro hook surface is fixedly connected to the top of one of the waterproof cloth strips, and a Velcro fleece surface is fixedly connected to the top of the other waterproof cloth strip, and the Velcro hook surface matches the Velcro fleece surface.

[0010] The matching of the Velcro hook surface and the Velcro fleece surface can enhance the tensile resistance of the zipper, thereby preventing the enlargement of the gap at the zipper seam due to excessive tension and the reduction of the sealing performance.

[0011] In a preferred embodiment, there is a gap between the waterproof cloth strip and the chain belt, and the pull head is located inside the gap between the waterproof cloth strip and the chain belt.

[0012] The gap is set so that the slider can be pulled more smoothly.

[0013] In a preferred embodiment, the outside of the teeth of the chain belt is sprayed with a hydrophobic film.

[0014] By spraying a hydrophobic film on the outside of the teeth of the chain belt, water can be prevented from continuing to penetrate through the gaps between the teeth of the chain belt when water penetrates, thereby further enhancing the sealing performance of the zipper.

[0015] Technical effects and advantages of the utility model:

[0016] 1. By pulling the slider, the two chain belts can be meshed, and at the same time, the opening and closing seat can be driven to move, so that the convex strip can be embedded in the concave strip, thereby preventing water from penetrating from the seam between the two waterproof cloth strips, thereby improving the sealing of the zipper;

[0017] 2. By coordinating the Velcro hook surface with the Velcro fleece surface, the tensile resistance of the zipper can be enhanced, avoiding excessive tension that causes the gap at the zipper seam to increase and reduce the sealing performance.

[0018] 3. By spraying a hydrophobic film on the outside of the teeth of the chain belt, water can be prevented from continuing to penetrate through the gaps between the teeth of the chain belt when water penetrates, thereby further enhancing the sealing of the zipper.

[0025] like Figure 1-3 As shown, the specific implementation method is: the waterproof cloth strip 2 can play a role of water isolation, and the two chain belts 1 can be meshed by pulling the slider 7. At the same time, the opening and closing seat 8 can be driven to move, so that the convex strip 4 can be embedded in the concave strip 3, so as to prevent water from penetrating from the joint of the two waterproof cloth strips 2, thereby improving the sealing of the zipper.

[0026] The concave strips 3 and the convex strips 4 are both rubber strips. The convex strips 4 are in an I-shape and are embedded in the concave strips 3 .

[0027] like Figure 1-3 As shown, the specific implementation is: the sealing performance of the zipper can be enhanced by embedding the I-shaped convex strip 4 into the concave strip 3.

[0028] A Velcro hook surface 5 is fixedly connected to the top of one of the waterproof cloth strips 2, and a Velcro fleece surface 6 is fixedly connected to the top of the other waterproof cloth strip 2, and the Velcro hook surface 5 matches the Velcro fleece surface 6.

[0029] like Figure 1-3 As shown, the specific implementation is: by cooperating with the Velcro hook surface 5 and the Velcro fleece surface 6, the tensile resistance of the zipper can be enhanced to avoid the increase of the gap at the zipper seam due to excessive tension and the reduction of the sealing performance.

[0030] There is a gap between the waterproof cloth strip 2 and the chain belt 1 , and the pull head 7 is located inside the gap between the waterproof cloth strip 2 and the chain belt 1 .

[0031] like Figure 2-3 As shown, the specific implementation is: the slider 7 can be pulled more smoothly by setting the gap.

[0034] Working principle of this utility model:

[0035] When using the zipper, firstly, the two chain belts 1 can be meshed by pulling the slider 7, and at the same time, the opening and closing seat 8 can be driven to move, so that the convex strip 4 can be embedded in the concave strip 3, so as to prevent water from penetrating from the seam between the two waterproof cloth strips 2, thereby improving the sealing performance of the zipper;

[0036] Subsequently, the Velcro hook surface 5 is adhered to the surface of the Velcro fleece surface 6. The Velcro hook surface 5 cooperates with the Velcro fleece surface 6 to enhance the tensile resistance of the zipper, thereby preventing excessive tension from increasing the gap at the zipper seam and reducing the sealing performance.
