Description

Commodity anti-theft device with anti-dismantling battery

Technical Field

The utility model belongs to the technical field of commodity anti-theft devices, and particularly relates to a commodity anti-theft device with a detachable battery.

Background

In the field of EAS article surveillance, the existing products in the market are mainly classified into two categories: the electronic tag is characterized by comprising 4 parts, namely a shell, a lock cylinder, a frequency element and an attachment device, and compared with the conventional hard tag, the electronic tag also comprises an electronic function module which can detect illegal unlocking or passing through a frequency element detection device (often called a detection antenna), and when the illegal unlocking or passing through the detection antenna occurs, the electronic tag can provide a self-alarm function. The component that supplies electrical energy to the electronic functional module of the electronic tag is a battery.

Generally, the battery mounting design has two types: one way to design the battery in a non-detachable way to improve the reliability of theft prevention is that the battery power is limited, and the tag loses the self-alarming function after the power is used up, thereby greatly shortening the service life of the product. In addition, the battery is designed to be detachable in another mode, and the battery can be replaced when the electric quantity is insufficient, so that the service life of the product is prolonged. The defect is that lawless persons can destroy the self-alarming function by disassembling the battery, thereby weakening the protection capability.

The detachable battery is usually fixed by screwing a battery cover. In order to prevent the battery from being disassembled by lawless persons, the battery is assembled and disassembled by a special screw and a special screwdriver. But inevitably, the battery can still be removed when a lawless person finds a suitable removal tool, thereby disabling the self-alarm function.
