Specific embodiment

In order to which the technical means, creative features, achievable purpose and effectiveness for realizing the utility model are easy to understand, under In conjunction with specific embodiments, the utility model is expanded on further in face.

The embodiment of the utility model provides a kind of anti-dismounting structure for the type active RFID electronic label for pasting class, ginseng Fig. 1 is seen, including type active RFID electronic label body 10, magnetic field generation section 20, magnetic induction part 30.Magnetic field generation section 20 is with non- Fixed form is installed on type active RFID electronic label body 10, so then can be in type active RFID electronic label body by from fixation After matrix separation magnetic field generation section is still allowed to be fixed on fixing base T, so as to fulfill magnetic field generation section and active RFID electronic Separation between label body 10.Type active RFID electronic label body 10 is provided with 20 mounting recess 100 of magnetic field generation section, described Magnetic field generation section 20 is installed on the recess portion in a manner of non-close-fitting, and magnetic field generation section is mounted on type active RFID electronic label with this structure On body 10.When type active RFID electronic label body 10 is pasted on fixing base T, which is fixed on fixed base Body T, and when type active RFID electronic label body 10 is disassembled by violence, due to magnetic field generation section and type active RFID electronic label sheet Body 10 is installed in a manner of on-fixed, so magnetic field generation section synchronous with type active RFID electronic label body 10 will not depart from fixed base Body.

With continued reference to Fig. 1, type active RFID electronic label is arranged at for magnetic field signal produced by detecting magnetic field generation section The magnetic induction part 30 of body 10, is connected to control module, the magnetic induction part include it is following any one or it is a variety of：Hall Element, anisotropic magnetoresistance element, giant magnetoresistance.And matched magnetic field generation section 20 include it is following any one or It is a variety of：Permanent magnet, electromagnet.

It is not difficult to find out from the discussion above, when adhesive surface is removed in violence, magnetic induction part 30 detects that magnetic force disappears or becomes Change, the chip on circuit board be set to after detecting alarm condition or can not working condition, so as to allow such active RFID electronic Label is not easy to be cracked easily, and security is stronger.

It is noted that the type active RFID electronic label body 10 uses multi-point magnetic induction structure, active RFID Multiple Magnetic Sensors, such as two magnetic induction parts 30 shown in Fig. 2, magnetic induction part connection are placed on electronic tag mainboard In circuit board 102, which is connected to antenna area 103 on plate, and circuit board is connected to battery portion 104.Referring to Fig. 3-5, Type active RFID electronic label adhesive surface is a plane, and there are two being set in the adhesive surface of type active RFID electronic label body 10 Circular hole corresponding with 30 position of magnetic induction part is as mounting recess, magnetic field generation section 20, type active RFID electronic label body 10 Adhesive surface be provided with glue, such as 3M glues.

In addition, the control module can allow type active RFID electronic label (here directly using circuit board as control module) Body 10 makes type active RFID electronic label body 10 fail after being removed fixing base by force, also or, directly allows and is connected to electricity The device of warning of road plate is warned.

Referring to Fig. 1, the assembling mode of the utility model is：
