Problems solved by technology

However, there is a metal part on the strap lock post of this wine bottle anti-theft device. The processing cost of this metal part is relatively high, and the injection molding of the lock post is also troublesome, with low efficiency and high cost.
Like the above-mentioned steel wire rope strap wine bottle anti-theft device, the strap tail is exposed, and the induction coil needs to be placed in another cavity, which greatly affects the appearance. When the lock cylinder is knocked, the inertia of the lock cylinder is large. (such as ordinary magnet attraction) when the locking spring compression force is weakened, the strap is easy to loosen
[0004] The release methods of the two above-mentioned wine bottle strap anti-theft devices are to use a strong magnet to attract the lock cylinder and the strap to disengage.

The anti-theft device includes one casing, one strap connected to the casing, and anti-theft EAS label inside the casing. The casing is provided with one strap port for the free end of the strap to pass through, one strap backstop comprising one locking block and one spring, and one unlocking hole for the unlocking unit to be inserted in. The unlocking unit includes one shell, one notch for holding the casing of the anti-theft device, and one shifting fork. The special unlocking unit can unlock the strap type anti-theft device easily and reliably.

Description

technical field [0001] The invention relates to an anti-theft device for commodities in supermarkets and self-selection markets, in particular to an anti-theft device for expensive alcohol in an Electronic Article Surveillance (EAS) system. Background technique [0002] There are many types of alcohol anti-theft devices in existing supermarkets and optional markets, one of which is a wire rope wine bottle anti-theft device. Belt, one-way locking with a metal lock cylinder. This kind of steel wire strap is covered with a soft rubber sleeve and tied tightly to the neck of the wine bottle. This type of wine bottle anti-theft device has its obvious disadvantages. First of all, the tail of the steel wire is exposed, and the induction coil needs to be placed in another cavity. After the strap is tied tightly, the shape of this cavity and the tail is too large, which is overwhelming for the wine bottle. In addition, the fixing of the steel wire rope is also relatively troublesom...
