Description

Anti-theft Tag {TAG FOR PROTECTING AGAINST BURGLARS}

The present invention relates to an anti-theft tag, and more particularly, to an anti-theft tag with improved durability by installing a cam member rotatable with a key member inside the case.

In general, an anti-theft tag is attached to a product displayed in a large store to check out the unpaid state of the product by generating an alarm when the user leaves the store in an unpaid state.

That is, the entrance and exit of the shop selling the goods for theft monitoring are provided with a transmission antenna and a reception antenna at predetermined intervals, and these antennas are electrically connected to the control unit. The control unit is configured to transmit a radio wave of a coil generating a resonant frequency installed in a tag at the same time and check the signal level of the received signal from the receiving antenna at all times, and a speaker for alarm is connected to the control output of the control unit. .

The anti-theft tag configured as described above resonates in a coil that generates a resonant frequency of a tag attached to an anti-theft article when radio waves transmitted from the transmitting antenna attempt to pass between the transmitting antenna and the receiving antenna without theft monitoring goods being paid. Therefore, the reception antenna receives a reception signal whose reception level is modulated. Accordingly, the control unit may check the unloading of the unpaid goods by alerting the speaker.

As shown, the anti-theft tag is composed of a pair of cases (1a) (1b), the coil spring (2) for generating a resonant frequency inside the case is seated and coupled with the tag pin (3) spring (4) ) Is built.

In addition, the tag pin insertion hole (4a) is formed in the central portion of the leaf spring (4) is easy pin coupling on one side, while the tag pin (3) is not separated from the other side.

That is, in order to separate the tag attached to the product for theft monitoring, it is possible to separate only by a separate release device (not shown).

However, the conventional anti-theft tag has a problem in that the elastic force of the leaf spring 4 itself is degraded by abrasion when used for a long time, so that the tag pin 3 is easily detached.

In addition, there is a problem that theft burglar breaks the anti-theft tag with a sharp tool or the like, and often releases the leaf spring 4 easily, thereby failing to perform the anti-theft function.

The present invention has been made to solve such a conventional problem, and an object thereof is to provide an anti-theft tag which improves durability by installing a cam member rotatable only by a key member in a case.
