[0018] Preferably, a waterproof coating is applied on the surface of the nylon sheet.

[0019] Preferably, a bulge is provided in the middle of the nylon sheet, and the bulge is convex upward.

[0020] Preferably, the top end of the protrusion is configured as an arc-shaped surface.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. The utility model has the advantage of arranging an elastic nylon sheet between the waterproof cloth A and the waterproof cloth B, so that the waterproof cloth A is pulled during the pulling process of the slider, causing the nylon sheet to expand and contract for buffering, thereby solving the problem that during the closing and opening process of the zipper, the cloth will be pulled but has no buffering ability, and is easily broken and damaged by strong pulling.

[0023] 2. The utility model has the advantage that, by providing the protrusions and the arc-shaped surface, the protrusions and the arc-shaped surface expand or contract accordingly during the process of the nylon sheet being pulled and stretched, thereby further enhancing the stretching ability of the nylon sheet.

[0032] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0033] Embodiment 1: An elastic waterproof zipper, see Figures 1 to 4 , comprising a zipper body 1 and a connecting structure 2;

[0034] The two connecting structures 2 are respectively arranged on two sides of the zipper body 1;

[0035] The connection structure 2 includes a waterproof cloth A201, a nylon sheet 202 and a waterproof cloth B203;

[0036] The inner end of the waterproof cloth A201 is connected to the chain tooth 101 of the zipper body 1; the zipper body 1 also includes a bottom stop 102, a slider 103 and a pull tab 104; the bottom stop 102 is fixedly arranged at the end of a row of chain teeth 101; wherein, the bottom stop 102 is connected to the inner end of a waterproof cloth A201; the slider 103 is movably arranged on the chain tooth 101; the pull tab 104 is movably arranged on the slider 103; the inner end of the nylon sheet 202 is connected to the outer end of the waterproof cloth A201; the inner end of the waterproof cloth B203 is connected to the outer end of the nylon sheet 202, and the outer end of the waterproof cloth B203 is connected to the object.

[0037] The utility model has the advantage of arranging a waterproof cloth A201, a nylon sheet 202 and a waterproof cloth B203, and arranging an elastic nylon sheet 202 between the waterproof cloth A201 and the waterproof cloth B203, so that the waterproof cloth A201 is pulled during the pulling process of the slider 103, causing the nylon sheet 202 to expand and contract for buffering, thereby solving the problem that during the pulling and closing process of the zipper, the cloth will be pulled but has no buffering ability, and is easily broken and damaged by strong pulling.

[0038] Specifically, a layer of waterproof coating is applied on the surface of the nylon sheet 202, which cooperates with the waterproof cloth A201 and the waterproof cloth B203 to achieve a waterproof effect.

[0039] Furthermore, a protrusion 2021 is provided in the middle of the nylon sheet 202 . The protrusion 2021 is convex upward, and a top end of the protrusion 2021 is provided as an arc surface 2022 .

[0040] The utility model has the advantage that the protrusions 2021 and the arc surface 2022 are provided, so that when the nylon sheet 202 is pulled and stretched, the protrusions 2021 and the arc surface 2022 expand or contract accordingly, thereby further enhancing the stretching ability of the nylon sheet 202 .

[0041] Working principle: When the device of the utility model is used, the outer end of the waterproof cloth B203 is connected to the object for installation, and the pull tab 104 is pulled to drive the pull head 103 to move along the chain teeth 101, so that the two rows of chain teeth 101 are engaged or opened, and the object is closed or opened. In the process of pulling the pull head 103, the pulling of the pull head 103 will pull the waterproof cloth A201, causing the nylon sheet 202 to be pulled. In the process of the nylon sheet 202 being pulled and stretched, the protrusion 2021 and the arc surface 2022 expand or contract accordingly, and the nylon sheet 202 stretches and contracts to perform buffering.

[0042] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
