A waterproof zipper

Abstract

This utility model discloses a waterproof zipper, including a front chain block. Zipper teeth are connected and installed on the connecting end face of the front chain block. A rear chain block is fixedly mounted on the rear surface of the front chain block. A waterproof protrusion is fixedly installed on the surface edge of the rear chain block. The waterproof protrusion can be made of rubber or silicone. This waterproof zipper, through the waterproof protrusion, better seals the gaps when tightened, thus giving the zipper a good sealing and waterproof effect. Furthermore, this structure has good shock absorption, resulting in a smoother feel and better zipping / closing experience.

Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and in particular to a waterproof zipper. Background Technology

[0002] Zippers are increasingly widely used, especially in clothing, bags and other items. However, these zippers have poor sealing and waterproofing properties, making them unsuitable for waterproof clothing. Furthermore, they vibrate and make noise when tightened, resulting in a poor feel when tightened. Therefore, we propose a waterproof zipper. Utility Model Content

[0003] The main purpose of this utility model is to provide a waterproof zipper that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A waterproof zipper includes a front chain block, with zipper teeth connected and installed on the connecting end face of the front chain block, a rear chain block fixedly provided on the rear surface of the front chain block, and a waterproof protrusion fixedly installed on the surface edge of the rear chain block.

[0005] Preferably, the waterproof protrusion 4 is selected from one of the following materials: rubber and silicone.

[0006] Preferably, the zipper is composed of multiple sets of the aforementioned front chain block, zipper teeth, rear chain block, and waterproof protrusion.

[0007] Preferably, the zipper teeth engage and are fixed with adjacent zipper teeth, and the zipper teeth press against the adjacent waterproof protrusions to form a seal.

[0008] Preferably, adjacent rear chain blocks are in close contact through waterproof protrusions to form a seal.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In this utility model, the waterproof zipper, through the setting of waterproof protrusions, makes the gaps when tightened better, thereby giving the zipper a good sealing and waterproof effect. In addition, the structure has a good shock absorption effect, and it is smoother and has a better feel when zipping and closing. Attached Figure Description

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] Example 1: like Figure 1-4 As shown, a waterproof zipper includes a front chain block 1, a zipper tooth 2 connected and installed on the connecting end face of the front chain block 1, a rear chain block 3 fixedly provided on the rear surface of the front chain block 1, and a waterproof protrusion 4 fixedly installed on the surface edge of the rear chain block 3. The waterproof protrusion 4 is selected from one of the following materials: rubber and silicone. Specifically, both rubber and silicone materials can provide a sealing and waterproof function, and make the zipper and zipper easier to operate, resulting in better performance.

[0014] The zipper is composed of multiple sets of front chain blocks 1, zipper teeth 2, rear chain blocks 3, and waterproof convex strips 4; Specifically, a single zipper tooth is composed of a front chain block 1, a zipper tooth 2, a rear chain block 3, and a waterproof protrusion 4, while the entire zipper is a structure composed of multiple zipper teeth.

[0015] The zipper teeth 2 interlock and are fixed with the adjacent zipper teeth 2, and are pressed onto the adjacent waterproof protrusions 4 to form a seal; Specifically, after the adjacent zipper teeth mesh, the zipper teeth 2 will press tightly against the waterproof protrusion 4, sealing the gap and preventing water from entering.

[0016] Adjacent rear chain blocks 3 are tightly sealed by waterproof protrusions 4; Specifically, there will be gaps between adjacent rear chain blocks 3 after the zipper is tightened. These gaps are sealed by filling them with waterproof protrusions 4, thus achieving a waterproof effect.

[0017] It should be noted that this utility model is a waterproof zipper. After the zipper is tightened, one side of the zipper tooth 2 will press tightly against the adjacent rear chain block 3. Because the rear chain block 3 is provided with a waterproof protrusion 4, the gap between them is sealed by the waterproof protrusion 4, thereby preventing water from flowing in. At the same time, the side of the waterproof protrusion 4 is in close contact with the adjacent waterproof protrusion 4, so that the gap between the adjacent rear chain blocks 3 is sealed. Therefore, the zipper has good sealing and waterproof performance. At the same time, the waterproof protrusion 4 has a shock-absorbing effect when the zipper is pulled, making the pulling and closing feel better and lighter.

[0018] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
