Metal core used in electronic anti-theft tags and manufacturing method thereof

Abstract

The invention provides a metal core used in electronic anti-theft tags, and the metal core comprises a body, bottom edges and middle edges. The body is provided with three, four or five side holes, a middle hole, a bottom hole and a top hole, wherein the middle hole is arranged below the top hole and above the bottom hole; and the quantity of the bottom edges and the quantity of the middle edges are the same as that of the side holes. The metal core provided by the invention also comprises at least one joint which longitudinally penetrates through the bottom edges and the body, the middle edges and the body, or the gap between the bottom edges and the middle edges and the body. The bottom edges are of a Y type, the middle edges are of a concave type, the bottom hole is formed by bending the bottom edges inwards, and the middle hole is formed by bending the middle edges inwards. The metal core used in the electronic anti-theft tags provided by the invention has the beneficial effects of high quality, low cost, high production efficiency, material conservation and simple production technique.

Description

Technical field [0001] The invention involves a metal core used for electronic anti -theft labels, which specifically involves the metal core in the locking device in the electronic anti -theft label. Background technique [0002] At present, most shopping malls and supermarkets use open shopping, and in order to prevent the stolen goods, merchants are deducted on the goods that are not easy to demolish anti -theft buckles. Most of them use electronic anti -theft labels.Electronic anti -theft labels must be opened by the unlocking device of the cashier. Once someone wants to bring the goods with electronic anti -theft labels out of the mall. When the anti -theft detection door at the exit, the detection door will issue a alarm signal to effectively prevent commodity theft.EssenceWith the increasing development of society and economy, the scope of the use of electronic anti -theft labels is becoming more and more wider, saving a lot of labor costs for merchants. [0003] The lock ...

AI Technical Summary

Problems solved by technology

The first generation of metal cores is an integrated production, so it has good stability and high quality, but because of the complex processing technology and completely manual production, the production speed is slow, the labor cost is high, and the production efficiency is very low.

Then, the second generation improvement was carried out, and the shell and liner were divided into three equal parts, and the liner was embedded in the shell. This kind of metal core liner is not integrated with the shell, resulting in easy sliding, poor stability, and a lot of waste of materials. , there are problems such as high production cost and troublesome installation
