Description

Technical Field

[0001] The utility model relates to the technical field of zipper design and manufacturing, and particularly relates to an electromagnetic wave-proof zipper. Background Art

[0002] As a general daily product, the zipper is widely used in various fields, such as clothing, luggage, tents, mosquito nets, etc. The zipper mainly consists of a plurality of zipper teeth provided on the left and right zipper fabrics, the left and right fabrics, and a slider for opening and closing the zipper teeth.

[0003] For the existing production process of zippers with electromagnetic wave-proof function, generally, a method of plating metal on the finished zipper is adopted. The metal layer after plating is relatively thin, and during use, since the zipper needs to be repeatedly pulled, the metal layer is likely to fall off, and the shielding effect is likely to become weak. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is as follows:

[0005] First, to provide an electromagnetic wave-proof zipper, a flexible metal material or a metal-plated wire with a relatively high plating thickness is used for weaving to form a dense fabric for making the zipper fabric to form a barrier for electromagnetic wave shielding.

[0006] Second, the zipper teeth and the slider are directly selected from existing alloy materials with better electromagnetic wave absorption and reflection performance, ensuring that the wear occurring during long-term use of the zipper teeth and the slider will not affect the shielding efficiency of the zipper.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] An electromagnetic wave-proof zipper includes two zipper teeth and a slider. On one side of the zipper teeth, there is a fabric woven from a wire with a metal coating or a flexible metal wire. The other side of the zipper teeth corresponds to the shape of the other side of the zipper teeth, and the slider is arranged on the zipper teeth.

[0009] This solution uses a fabric woven from a wire with a metal coating or a flexible metal wire and combines zipper teeth and a slider made of an alloy material with better electromagnetic wave absorption and reflection performance to form a complete electromagnetic wave-proof zipper. Even after long-term use and wear, it will not have the problem of reduced shielding effect like the plated metal in the existing technology.

[0010] Optionally, the slider includes a slider body and a pull tab. The slider body is arranged on the zipper teeth. A first moving hole for the pull tab to move is provided on the slider body, and a first moving part corresponding to the first moving hole is provided on the pull tab.

[0011] The pull tab is connected in a movable manner to ensure that the pull tab can be pulled from various angles during use.

[0012] Optionally, a covering piece is provided at one end of the pull tab far from the first movable portion.

[0013] The covering piece is mainly used to block the gap between the slider and the zipper teeth, reducing the possibility of foreign objects entering the gap.

[0014] Optionally, a locking member is provided at the covering piece near the slider.

[0015] Optionally, the locking member includes a locking protrusion and a locking recess. The locking protrusion is provided on the slider body, and the locking recess is provided on the covering piece. The locking protrusion and the locking recess are in shape fit.

[0016] Optionally, the locking member includes a locking protrusion and a locking recess. The locking protrusion is provided on the covering piece, and the locking recess is provided on the slider body. The locking protrusion and the locking recess are in shape fit.

[0017] The locking member adopts a simple form of interlocking of protrusions and recesses, which has a low cost and is easy to be unlocked by hand. It can also ensure that the pull tab will not shake relative to the slider due to slight external force, preventing the pull tab from colliding with the slider to generate noise.

[0018] The beneficial technical effect of the present utility model is that a complete anti-electromagnetic wave zipper is formed by using a cloth woven from a wire with a metal coating or a flexible metal wire and alloy materials with better absorption and reflection performance of electromagnetic waves for the zipper teeth and the slider. After long-term use and wear, it will not have the problem of reduced shielding effect like the plated metal in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0024] Referring to Figures 1-3 As shown, an electromagnetic wave-proof zipper includes two zipper teeth 1 and a slider. A fabric 2 woven from silk threads with a metal coating or flexible metal wires is provided on one side of the zipper teeth 1. The other side of the zipper teeth 1 corresponds to the shape of the other side of the zipper teeth 1, and the slider is arranged on the zipper teeth 1.
