Description

Rotatable sensor for commodity theft prevention

Technical Field

The utility model relates to a commodity theftproof field especially relates to a sensor for commodity theftproof.

Background

With the development of science and technology, electronic products or some commodities with inherent functions are usually displayed by a seller for the experience of the consumer, so that the consumer can feel the functions and advantages of the commodities more intuitively.

The mode of show sale can let consumer and commodity zero distance contact, and is natural, has just also increased the stolen or impaired risk of commodity, therefore show commodity theftproof just the branch of commodity theftproof just arises as one's turn to, show commodity theftproof and retail's theftproof such as EAS in the prior art is slightly different, the theftproof of retail trade can be kept apart commodity and seller, but show commodity theftproof need both guarantee consumer and commodity (showpiece) the abundant contact, the security of commodity is guaranteed as far as possible in this kind of close contact's environment again, this is the particularity of show commodity theftproof.

Since display and sales are widely used in the field of electronic products, on one hand, in order to simplify the structure and on the other hand, in order to more accurately sense whether the merchandise is in a safe state, the merchandise anti-theft device in the prior art is mostly combined with the charging interface of the merchandise, for example, it is common in the prior art to connect the sensor in the form of a connector, on the one hand, the sensor is connected to the charging interface of the merchandise to supply power to the merchandise, on the other hand, the sensor itself is physically connected to the merchandise through a fixing device as a fixing mode of the sensor and also as another standard for detecting whether the merchandise is in a safe state, and the sensor itself is connected to an alarm device, a monitoring device or an external power supply through a cable, for example, when the charging interface of the merchandise is powered off, it indicates that the merchandise may be separated from the sensor, the part of the physical connection between the sensor and the commodity can be provided with a contact sensor, at the moment, whether the sensor is separated from the commodity or not can be directly sensed, once the power supply disconnection or the physical connection disconnection between the sensor and the commodity is caused, the commodity can be considered to be in a stolen risk, and the sensor can send an alarm signal or a safety signal to an alarm device or a monitoring device through a cable, so that staff in a display place can be reminded.

As mentioned above, the sensor or a part of the sensor is usually fixedly connected with the cable, and in the process of commodity experience, since the sensor is often taken up or put down along with the commodity, the cable is inevitably subjected to tensile force or torsional force in various directions, and the joint of the cable and the sensor is easily damaged.
