Description

Technical Field

[0001] The utility model belongs to the technical field of commodity anti-theft, and in particular relates to a commodity anti-theft device. Background Art

[0002] In the field of EAS product theft prevention, there is a type of bundled product anti-theft tags, which are fixed to paper boxes, cartons and other products by means of wire rope bundling. The bundled product anti-theft tags have built-in frequency elements and lock cores. The lock core prevents the anti-theft tags from being removed from the products without authorization. If someone takes the products out of the supermarket without authorization, the frequency element will trigger the detector at the door (commonly known as the "EAS antenna") to alarm.

[0003] The structure of the bundled commodity anti-theft tag consists of a tag body, a steel wire rope and a threading plate. The main part can be divided into a shell, a winding shaft, a locking structure and an electronic component. After the steel wire rope passes through the threading plate and the shell, both ends are connected to the electronic component to form a power circuit. Both ends of the electronic component and the steel wire rope are fixed on the winding shaft. The winding shaft is placed in the shell and can rotate. When it rotates, the steel wire rope is wound around the winding shaft, tightening the steel wire rope, thereby bundling the tag to the commodity. There is a type of small packaged goods with hook holes on the market. The shelf display space is limited. The existing bundled commodity anti-theft tags are too large. After being bundled with the goods, they greatly occupy the display space of the goods and reduce the number of goods on display. Utility Model Content

[0030] 2. When unlocking is required, first use the remote control to send the unlock password to the product anti-theft device. After receiving the unlock password, the product anti-theft device will check it with the password stored in the MCU. When the unlock password is consistent with the internal password, the PCB component 2 will give a sound and / or light prompt, and then pull the rope loosening button 53 inward. After the steel ball 52 slides, the gap becomes larger, and the wire rope 3 can be pulled back to loosen the rope. At this time, the PCB component 2 will not trigger the alarm.

[0031] 3. The outer ring of the first housing 1 of the commodity anti-theft device is provided with a plurality of rope buckles 15. If the commodity to be protected is small, the steel wire rope 33 can be inserted into the rope buckle 15 to fix the steel wire rope 33 when it is extended far.
