AI Technical Summary
Traditional waterproof zippers lack effective waterproof performance at the chain elements when engaged, resulting in low waterproofing grade, limited use, and poor overall effect.
A reinforced watertight zipper is designed, with a waterproof layer and a equidistant arranged cable element on the fabric strip. A waterproof adhesive strip connected to the waterproof layer is provided on the outside of each row of cable element. The waterproof adhesive strip covers the cable element when it is close to it, and the cover strip covers the gaps of the glue strip to enhance the waterproof effect.
When the zipper is closed, the waterproof adhesive strip is close to the cover element, and the cover strip covers the gap, significantly improving the waterproof performance and achieving better sealing effect.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of zipper manufacturing, and more specifically, to an enhanced watertight zipper. Background Art
[0002] The conventional waterproof zipper only has a waterproof layer on the cloth tape, and when the zipper is closed, the meshing chain teeth still do not have good waterproof performance, and the waterproof grade is low, the use is limited, and the overall effect is not good. Accordingly, the utility model proposes an enhanced watertight zipper. Utility Model Content
[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide an enhanced watertight zipper.
[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows: the utility model involves an enhanced watertight zipper, including two matching cloth tapes, each of which is provided with a row of chain teeth equidistantly arranged along its extension trajectory, the outer end surface of the cloth tape is provided with a waterproof layer, and the outer side of each row of chain teeth is provided with a waterproof rubber strip connected to the waterproof layer, any one of the waterproof rubber strips is tightly attached to the other waterproof rubber strip, and a cover strip is provided on one side of the gap between the two waterproof rubber strips, and the cover strip is connected to one of the waterproof rubber strips.
[0005] The utility model is further configured as follows: the waterproof layer and the waterproof rubber strip on the same cloth belt are integrated.
[0006] The utility model is further configured as follows: the cover strip and the waterproof rubber strip connected thereto are integrated.
[0007] The utility model is further configured as follows: the waterproof layer, the waterproof rubber strip and the cover strip are all made of TPU, EVA, PE, PP, PVC or rubber.
[0008] In summary, the utility model has the following beneficial effects:
[0009] 1. When the zipper is in the closed state, the two waterproof strips are tightly attached to cover the chain teeth that are bitten together to achieve a waterproof effect.
[0010] 2. When the zipper is in the closed state, the cover strip blocks the gap between the two waterproof strips to enhance the waterproof effect. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the overall structure of the utility model;
[0012] Figure 2 It is a structural schematic diagram of another state of the utility model. DETAILED DESCRIPTION
[0013] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.
[0014] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0015] Example 1
[0016] See also Figure 1 and Figure 2 As shown, the enhanced watertight zipper involved in this embodiment includes two matching cloth tapes 1, each of which is provided with a row of chain teeth 2 arranged equidistantly along its extension trajectory, the outer end surface of the cloth tape 1 is provided with a waterproof layer 3, and the outer side of each row of chain teeth 2 is provided with a waterproof rubber strip 4 connected to the waterproof layer, any of the waterproof rubber strips 4 is tightly attached to the other waterproof rubber strip 4, and a cover strip 5 is provided on one side of the gap between the two waterproof rubber strips 4, and the cover strip 5 is connected to one of the waterproof rubber strips 4.
[0017] Furthermore, the waterproof layer 3 and the waterproof rubber strip 4 on the same cloth tape 1 are integrated.
[0018] Furthermore, the cover strip 5 and the waterproof rubber strip 4 connected thereto are integrated.
[0019] Furthermore, the waterproof layer 3, the waterproof rubber strip 4 and the cover strip 5 are all made of TPU, EVA, PE, PP, PVC or rubber.
[0020] In this embodiment, when the zipper is closed, the link teeth 2 on one cloth tape 1 are engaged with the link teeth of another cloth tape 1, and the two waterproof rubber strips 4 are tightly attached to cover the engaged link teeth 2, serving as a primary seal; the cover strip 5 covers the gap between the two adjacent waterproof rubber strips 4, serving as a secondary seal.
[0021] The enhanced watertight zipper involved in the utility model has two waterproof rubber strips that are tightly attached to cover the chain teeth that are bitten together when the zipper is in a closed state, thereby achieving a waterproof effect; and when the zipper is in a closed state, the cover strip blocks the gap between the two waterproof rubber strips to achieve an enhanced waterproof effect. The overall function is perfect and the practicability is strong.
