Description

Technical Field

[0001] The present invention relates to the technical field of electronic tags, and in particular to an RFID electronic tag with an anti-disassembly structure. Background Art

[0002] The Chinese name of RFID is radio frequency identification technology, which is a contactless automatic identification technology. RFID consists of tags, readers and antennas. It has high application value in various links such as procurement, storage, loading and unloading, transportation and assembly. In the logistics system, electronic tags will be installed on the surface of the logistics box to facilitate the viewing of specific logistics information.

[0003] However, the existing logistics box electronic tags still have the following two shortcomings in use: First, after the electronic tag is installed on the surface of the logistics box, there is no anti-tampering structure for the tag. When the electronic tag is removed, the control center cannot be notified immediately. Secondly, in order to increase the stability of the electronic tag on the surface of the logistics box, bolts are used to fix it. However, when driving on rugged roads, the logistics box will shake, which can easily cause the bolts on the surface of the tag to loosen. Summary of the invention

[0004] In view of this, the present invention provides an RFID electronic tag with an anti-dismantling structure to solve the problem that the current electronic tags lack an anti-dismantling structure. When the electronic tag is disassembled, the control center cannot be notified immediately, and when driving on rugged roads, the logistics box will also shake, which may easily cause the bolts on the surface of the tag to loosen.

[0005] The present invention provides an RFID electronic tag with an anti-disassembly structure, which specifically includes: a base; A rectangular slot is provided in the middle of the front end of the base, two groups of connection holes are symmetrically provided on the surface of the base, and two device slots are symmetrically provided inside the base; A label shell, wherein the label shell is fixedly mounted in a card slot on the front end surface of the base, a cavity is provided inside the label shell, and a microchip is installed inside the cavity; A sliding plate, the sliding plate is slidably mounted in a device slot inside the base, and a clamping block is fixedly mounted at the middle position of the outer end surface of the sliding plate; A second fixing frame, wherein the second fixing frame body is a U-shaped structure, the second fixing frame is fixedly mounted on the bottom surface of the device slot, and a warning mechanism is mounted on the surface of the second fixing frame; A compression spring is located inside the device groove, one side of the inner end of the compression spring is fixedly connected to the bottom end of the device groove, and one side of the outer end of the compression spring is fixedly connected to the sliding plate.

[0006] Furthermore, a first fixing frame is fixedly mounted on the inner end surface of the sliding plate, the main body of the first fixing frame is a U-shaped structure, and a conductive block is fixedly mounted on the inner end surface of the first fixing frame.

[0007] Furthermore, the warning mechanism includes: A fixed block is provided with a slot inside, and a conductive plate is respectively installed on the inner end surfaces of the upper and lower ends of the slot, and the fixed block is aligned with the conductive block.

[0008] Furthermore, the warning mechanism also includes: a signal transmitter, which is fixedly mounted on the inner end surface of the second fixing frame, and the signal transmitter is connected to the conductive plate at the lower end of the slot through a wire; a power supply assembly, which is fixedly mounted on the inner end surface of the second fixing frame, and the front end of the power supply assembly is connected to the conductive plate at the top end of the slot through a wire, and the rear end of the power supply assembly is connected to the signal transmitter through a wire.

[0009] Furthermore, the front end of the card block is an inclined structure, and plugs are evenly installed on the outer end of the card block.

[0010] Furthermore, four antennas are installed on the surface of the microchip, and the four antennas are arranged in a ring structure.

[0011] Furthermore, the connecting hole body is a convex structure, and the connecting hole in the middle is connected to the device groove.

[0012] Furthermore, drainage grooves are evenly formed on the rear end surface of the base, and the main body of the drainage grooves is an arc-shaped structure.

[0013] The present invention provides an RFID electronic tag with an anti-disassembly structure, which has the following beneficial effects: Specific usage and function of this embodiment: when the bolt inside the connecting hole is taken out, the bolt loses its limiting effect on the external block of the sliding plate. A compression spring is installed on the inner end surface of the sliding plate. Under the action of the elastic force of the compression spring, the sliding plate and the first fixing frame will move outward, and the conductive block on the surface of the first fixing frame will be inserted into the slot on the surface of the fixing block. The conductive block will fit with the conductive plates at the upper and lower ends of the slot. At this time, a closed loop is formed between the signal transmitter and the power supply component. The signal transmitter will emit information outward when powered on, and the information is transmitted to the control terminal to remind the electronic tag to be violently disassembled.

[0014] In addition, when the tag enters the magnetic field, it receives the radio frequency signal sent by the reader and sends out the product information stored in the microchip with the energy obtained from the induced current. After the reader reads and decodes the information, it is sent to the central information system for relevant data processing. There are four antennas installed in a ring shape on the surface of the microchip. The antenna transmits electromagnetic waves between the reader and the electronic tag to achieve wireless communication. The antenna emits electromagnetic energy to activate the electronic tag and provides the tag with the DC energy required for operation. The antenna can also send or receive radio frequency signals to achieve data transmission and reception.

[0015] In addition, when the base is installed on the outer surface of the logistics box, when the temperature changes, some water droplets will form on the outer wall of the logistics box. The drainage grooves are evenly opened on the rear end surface of the base, so that there can be a certain gap between the base and the logistics box, which is convenient for the circulation of gas. Moreover, the water droplets sliding down from the top of the logistics box can pass through the base from the inside of the drainage groove, avoiding the water droplets from flowing through the surface of the label shell, thereby avoiding adverse effects on the microchip inside the label shell.

[0016] In addition, when workers fix the base on the outer surface of the logistics box, they can use fixing screws to pass through the base and wedge into the surface of the logistics box. When the fixing screws are screwed into the surface of the logistics box, some debris will be rotated out and remain between the base and the logistics box, which will cause the stability of the base outside the logistics box to deteriorate. By setting the connecting hole as a convex structure, the rotated debris can be stored inside the connecting hole, ensuring the cleanliness between the base and the logistics box.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of specific embodiments of the present invention.

[0022] Example 1: Please refer to Figures 1 to 8 As shown: The present invention provides an RFID electronic tag with an anti-disassembly structure, comprising a base 1; A rectangular slot 102 is provided in the middle of the front end of the base 1, two groups of connection holes 101 are symmetrically provided on the surface of the base 1, and two device slots 104 are symmetrically provided inside the base 1; The tag housing 2 is fixedly mounted in the card slot 102 on the front surface of the base 1, and a cavity 201 is provided inside the tag housing 2, and a microchip 3 is installed inside the cavity 201; The sliding plate 4 is slidably mounted in the device groove 104 inside the base 1, and a clamping block 401 is fixedly mounted at the middle position of the outer end surface of the sliding plate 4; A second fixing frame 5, the main body of the second fixing frame 5 is a U-shaped structure, the second fixing frame 5 is fixedly mounted on the bottom surface of the device slot 104, and a warning mechanism is installed on the surface of the second fixing frame 5; The compression spring 9 is located inside the device groove 104 , one side of the inner end of the compression spring 9 is fixedly connected to the bottom end of the device groove 104 , and one side of the outer end of the compression spring 9 is fixedly connected to the sliding plate 4 .

[0023] Among them, the inner end surface of the sliding plate 4 is fixedly installed with a first fixing frame 402, the main body of the first fixing frame 402 is a U-shaped structure, and the inner end surface of the first fixing frame 402 is fixedly installed with a conductive block 4021. During use, when there is no bolt inside the connecting hole 101, under the action of the elastic force of the compression spring 9, the sliding plate 4 is located at the outermost end of the device groove 104. When the sliding plate 4 moves outward, the conductive block 4021 will be inserted into the slot 601 inside the fixed block 6.

[0024] Among them, the warning mechanism includes: a fixed block 6, a slot 601 is opened inside the fixed block 6, a conductive plate 6011 is installed on the inner end faces of the upper and lower ends of the slot 601 respectively, and the fixed block 6 is aligned with the conductive block 4021; a signal transmitter 7, the signal transmitter 7 is fixedly installed on the inner end face of the second fixed frame 5, and the signal transmitter 7 is connected to the conductive plate 6011 at the lower end of the slot 601 through a wire; a power supply component 8, the power supply component 8 is fixedly installed on the inner end face of the second fixed frame 5, the front end of the power supply component 8 is connected to the conductive plate 6011 at the top of the slot 601 through a wire, and the rear end of the power supply component 8 is connected to the signal transmitter 7 through a wire.

[0025] By adopting the above scheme, the technical effect brought about is: when the bolt passes through the connecting hole 101 to fix the base 1 on the surface of the logistics box, the bolt in the connecting hole 101 can push the block 401 in the direction of the device slot 104, and the sliding plate 4 and the first fixing frame 402 will also move toward the inside of the device slot 104. At this time, the conductive block 4021 will not be connected to the slot 601 inside the fixing block 6, so a closed loop cannot be formed between the power supply component 8 and the signal transmitter 7, and the signal transmitter 7 will not emit a signal to the outside, indicating that the electronic tag is still installed on the outside of the logistics box. When the bolt inside the connecting hole 101 is taken out, it means that the electronic tag is After being removed, the bolt loses its limiting effect on the external block 401 of the sliding plate 4. The compression spring 9 is installed on the inner end surface of the sliding plate 4. Under the action of the elastic force of the compression spring 9, the sliding plate 4 and the first fixing frame 402 will move outward, and the conductive block 4021 on the surface of the first fixing frame 402 will be inserted into the slot 601 on the surface of the fixing block 6. The conductive block 4021 will fit with the conductive plates 6011 at the upper and lower ends of the slot 601. At this time, a closed loop is formed between the signal transmitter 7 and the power supply component 8. The signal transmitter 7 will emit information outward when powered on. The information is transmitted to the control terminal to remind the electronic tag that it has been violently disassembled.

[0026] Among them, the front end of the block 401 is an inclined structure, and the outer end of the block 401 is evenly installed with a plug 4011. During use, when the fixing bolt passes through the connecting hole 101 to fix the base 1, the lower end part of the fixing bolt located in the connecting hole 101 is exposed. At this time, the plug 4011 at the front end of the block 401 will be clamped in the thread on the surface of the bolt, which can achieve fixed limiting of the bolt. When the logistics box is bumpy, the bolt inside the connecting hole 101 will not fall off easily.

[0027] Among them, four antennas 301 are installed on the surface of the microchip 3, and the four antennas 301 are arranged in a ring structure. During use, when the tag enters the magnetic field, it receives the radio frequency signal emitted by the reader, and sends out the product information stored in the microchip 3 by means of the energy obtained by the induced current. After the reader reads and decodes the information, it is sent to the central information system for relevant data processing. Four antennas 301 are installed in a ring shape on the surface of the microchip 3. The antenna 301 transmits electromagnetic waves between the reader and the electronic tag to realize wireless communication, and the antenna 301 emits electromagnetic energy to activate the electronic tag and provide the tag with the DC energy required for operation. The antenna 301 can also send or receive radio frequency signals to realize data transmission and reception.

[0028] Embodiment 2: The present invention provides an RFID electronic tag with an anti-disassembly structure. Based on Embodiment 1, Figure 1-Figure 8 As shown, it also includes: wherein, the rear end surface of the base 1 is evenly provided with drainage grooves 103, and the main body of the drainage grooves 103 is an arc-shaped structure. During use, when the base 1 is installed on the outer end surface of the logistics box, when the temperature changes, some water droplets will form on the outer wall of the logistics box. The drainage grooves 103 are evenly provided on the rear end surface of the base 1, so that there can be a certain gap between the base 1 and the logistics box, which is convenient for the circulation of gas, and the water droplets sliding down from the top of the logistics box can pass through the base 1 from the inside of the drainage grooves 103, thereby preventing the water droplets from flowing through the surface of the label shell 2, thereby avoiding adverse effects on the microchip 3 inside the label shell 2.

[0029] Embodiment 3: The present invention provides an RFID electronic tag with an anti-disassembly structure. Based on Embodiment 1, Figure 1-Figure 8As shown, it also includes: the main body of the connecting hole 101 is a convex structure, and the middle connecting hole 101 is connected with the device groove 104. During use, when the worker fixes the base 1 on the outer surface of the logistics box, the fixing screw can be used to pass through the base 1 and wedge into the surface of the logistics box. When the fixing screw is screwed into the surface of the logistics box, some debris will be rotated out and remain between the base 1 and the logistics box, which causes the stability of the base 1 outside the logistics box to deteriorate. By setting the connecting hole 101 as a convex structure, the rotated debris can be stored inside the connecting hole 101, ensuring the cleanliness between the base 1 and the logistics box.

[0030] Specific usage and function of this embodiment: In the present invention, when the base 1 is installed on the outer surface of the logistics box, when the temperature changes, some water droplets will form on the outer wall of the logistics box. The drainage groove 103 is evenly opened on the rear end surface of the base 1, so that there can be a certain gap between the base 1 and the logistics box, which is convenient for the circulation of gas, and the water droplets sliding down from the top of the logistics box can pass through the base 1 from the inside of the drainage groove 103, avoiding the water droplets from flowing through the surface of the label shell 2, and avoiding adverse effects on the microchip 3 inside the label shell 2. When the worker fixes the base 1 on the outer surface of the logistics box, he can use a fixing screw to pass through the base 1 and wedge into the surface of the logistics box, and the fixing screw is screwed into the surface of the logistics box. When the surface is touched, some debris will be rotated out and remain between the base 1 and the logistics box, which makes the stability of the base 1 outside the logistics box worse. By setting the connection hole 101 as a convex structure, the rotated debris can be stored inside the connection hole 101, ensuring the cleanliness between the base 1 and the logistics box. When the bolt passes through the connection hole 101 to fix the base 1 to the surface of the logistics box, the bolt in the connection hole 101 can push the block 401 toward the device slot 104. At this time, the sliding plate 4 and the first fixing frame 402 will also move toward the inside of the device slot 104. At this time, the conductive block 4021 will not be stuck in the slot 601 inside the fixing block 6, so the power supply component 8 and the signal transmitter 7 are connected. A closed loop cannot be formed, and the signal transmitter 7 will not emit signals outward, indicating that the electronic tag is still installed on the outside of the logistics box. When the bolt inside the connecting hole 101 is taken out, it means that the electronic tag has been removed. At this time, the bolt loses its limiting effect on the external block 401 of the sliding plate 4. The compression spring 9 is installed on the inner end surface of the sliding plate 4. Under the action of the elastic force of the compression spring 9, the sliding plate 4 and the first fixing frame 402 will move outward, and the conductive block 4021 on the surface of the first fixing frame 402 will be inserted into the slot 601 on the surface of the fixing block 6. The conductive block 4021 will fit with the conductive plates 6011 at the upper and lower ends of the slot 601. At this time, a closed loop is formed between the signal transmitter 7 and the power supply component 8. The signal transmitter 7 will emit information when powered on, and the information will be transmitted to the control terminal to remind the electronic tag to be violently disassembled. When the tag enters the magnetic field, it receives the radio frequency signal emitted by the reader, and sends out the product information stored in the microchip 3 by means of the energy obtained by the induced current. The reader reads and decodes the information and sends it to the central information system for relevant data processing. Four antennas 301 are installed in a ring shape on the surface of the microchip 3. The antenna 301 transmits electromagnetic waves between the reader and the electronic tag to realize wireless communication, and the antenna 301 emits electromagnetic energy to activate the electronic tag and provide the tag with the DC energy required for operation. The antenna 301 can also send or receive radio frequency signals to realize data transmission and reception.
