AI Technical Summary
Traditional waterproof zippers have insufficient waterproof performance at the meshing point, resulting in a low waterproof rating and limited use.
Waterproof strips are sewn onto nylon zipper tapes, and gaps in the tapes are covered with cap strips to form a multi-layered waterproof structure, including a combination design of nylon zipper tapes, waterproof strips, and cap strips.
The zipper achieves a high waterproof rating by reducing its overall thickness while enhancing its waterproof performance.

[0010] In summary, the utility model has the following beneficial effects:
[0011] 1. When the zipper is in the closed state, the two waterproof adhesive strips are in close contact, covering the engaged teeth, achieving waterproof effect.
[0012] 2. When the zipper is in the closed state, the cover strip covers the gap between the two waterproof adhesive strips, achieving enhanced waterproof effect.
[0013] 3. The cover strip is arranged between the two zipper strips, which can ensure the waterproof level while reducing the overall thickness of the zipper. BRIEF DESCRIPTION OF DRAWINGS
[0014] Figure 1 is the overall structure schematic view of the utility model;
[0015] Figure 2 is the structure schematic view of another state of the utility model. DETAILED DESCRIPTION
[0016] In order to make the skilled in the art better understand the technical scheme of the utility model, the preferred embodiment of the utility model is described below in combination with specific examples, but it should be understood that these descriptions are only to further illustrate the features and advantages of the utility model, and are not limit the utility model patent claims. Based on the examples in the utility model, all other examples obtained by the ordinary skilled in the art without creative labor are within the scope of protection of the utility model.
[0017] The utility model is further illustrated below in combination with the drawings and preferred examples.
[0018] Example 1
[0019] Referring to Figure 1 and Figure 2 , the utility model relates to a nylon water-tight zipper, which comprises a first zipper strip 1 and a second zipper strip 2 used in combination, a row of teeth 3 is arranged equidistantly along the extension track on the first zipper strip 1 and the second zipper strip 2 respectively, a first waterproof adhesive strip 4 is sewn between the first zipper strip 1 and the teeth thereon, and a second waterproof adhesive strip 5 is sewn between the second zipper strip 2 and the teeth thereon, when the teeth on the first zipper strip 1 and the teeth on the second zipper strip 2 are in the engaged state, one end of the first waterproof adhesive strip 4 facing the second waterproof adhesive strip is in close contact with one end of the second waterproof adhesive strip 5 facing the first waterproof adhesive strip, a cover strip 6 connected with the first waterproof adhesive strip is arranged between the first zipper strip 1 and the second zipper strip 2, and the cover strip 6 covers the spliced gap between the first waterproof adhesive strip 4 and the second waterproof adhesive strip 5.
[0020] Further, the cover strip 6 and the first waterproof adhesive strip 4 are integrated.
[0021] Further, the first zipper strip 1 and the second zipper strip 2 are both nylon zipper strips.
[0022] Further, the first waterproof adhesive tape 4, the second waterproof adhesive tape 5 and the cover strip 6 are all TPU, EVA, PE, PP, PVC or rubber.
[0023] In the embodiment, when the zipper is closed, the teeth 3 on the first zipper tape 1 are engaged on the teeth 3 on the second zipper tape 2, and one end of the first waterproof adhesive tape 4 facing the second waterproof adhesive tape is tightly attached to one end of the second waterproof adhesive tape 5 facing the first waterproof adhesive tape, so as to achieve the function of shielding the teeth 3, as a primary seal; at the same time, the cover strip 6 covers the gap between the two attached waterproof adhesive tapes, as a secondary seal.
[0024] In the embodiment, since there is a space between the first zipper tape 1 and the second zipper tape 2 for the cover strip 6 to be placed in, the cover strip 6 can be arranged to be embedded, so that the whole zipper is more flat.
