When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it may be directly set on the other mechanism or there may be a centered mechanism at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] like Figures 1 to 3 As shown, the utility model is a disassembly-proof electronic tag, including an electronic tag body 107, a shell 101, a fixing component 200, and a disassembly component 300; a chip 103, a battery 105, and an identifier 106 are fixedly installed inside the electronic tag body 107, an antenna 104 is fixedly connected to the chip 103, a card insertion slot 102 is fixedly installed on the top of the identifier 106, and one end of the card insertion slot 102 passes through the inner wall of the shell 101 and the electronic tag body 107.

[0022] The fixing assembly 200 includes a first fixing plate 201 and a second fixing plate 202. The first fixing plate 201 is symmetrically fixedly installed on the inner wall of the shell 101, and the second fixing plate 202 is symmetrically fixedly installed on the outer wall of the electronic tag body 107. The first fixing plate 201 and the second fixing plate 202 are provided with aligned fixing grooves 207, and a fixing plug 203 is slidably installed in the fixing groove 207. The bottom of the fixing plug 203 is provided with an inclined surface, and the fixing plug 203 is provided with aligned through holes. A sleeve 204 is slidably installed in the through hole. The sleeve 204 is slidably installed on a slide bar 205. The slide bar 205 is symmetrically fixedly connected to the outer wall of the electronic tag body 107. A support spring 206 is installed around the slide bar 205, and the support spring 206 is fixedly installed between one end of the sleeve 204 and the outer wall of the electronic tag body 107.

[0023] The disassembly component 300 includes a fixed cylinder 303, which is symmetrically fixedly installed on the inner wall of the electronic tag body 107. A coil 304 is fixedly installed in the cylinder wall of the fixed cylinder 303. The battery 105 and the chip 103, the antenna 104, the identifier 106, and the coil 304 are electrically connected. A metal rod 302 is slidably installed in the fixed cylinder 303, and planes are symmetrically provided on the side of the metal rod 302. The other end of the metal rod 302 passes through the through hole 305 and is connected to the fixed block 301. The fixed block 301 is fixedly installed on the outer wall of the sleeve 204 at one end close to the sliding rod 205.

[0024] In the utility model, a slope is provided at the bottom of the fixed plug 203. When inserted, the slope pushes the sleeve 204 to slide on the slide rod 205 and compresses the support spring 206, so that the fixed plug 203 can be smoothly inserted. The side surfaces of the metal rod 302 are symmetrically provided with planes, so that when the metal rod 302 slides in the fixed tube 303, a gap is formed between the plane on the metal rod 302 and the inner wall of the fixed tube 303 and the through hole 305, so that the internal and external air pressures are balanced, thereby reducing the sliding resistance of the metal rod 302.

[0025] Working principle: The electronic tag body 107 and the housing 101 are connected, the first fixing plate 201 and the second fixing plate 202 are in contact, and the fixing plug 203 is inserted. The inclined surface on the fixing plug 203 pushes the sleeve 204 to deviate, so that the fixing plug 203 is inserted. The sleeve 204 slides into the perforation on the fixing plug 203 under the push of the support spring 206, and the electronic tag body 107 and the housing 101 are fixed. The fixing plug 203 cannot be pulled out, and the electronic tag cannot be disassembled by non-violent means. When it is necessary to disassemble, the identity card is inserted into the card slot 102 and identified by the identifier 106. After successful identification, the coil 304 is energized to generate a magnetic field to suck the metal rod 302 into the fixed tube 303. The metal rod 302 pulls the fixed block 301, and the fixed block 301 drives the sleeve 204 to disengage from the perforation on the fixed plug block 203. The fixed plug block 203 is taken out of the fixed slot 207, and the shell 101 and the electronic tag body 107 are separated, thereby achieving the purpose of improving the anti-theft performance of the electronic tag.
