[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 3 In an embodiment of the utility model, an RFID tag with an anti-transfer function includes an RFID pallet tag 1 and mounting holes 2 opened at four end corners of the RFID pallet tag 1, an anti-transfer component 3 is arranged inside the mounting hole 2, and the anti-transfer component 3 is used to fit and snap with the outer wall of the screw when the RFID pallet tag 1 is fixed by a screw, so as to damage the anti-transfer component 3 when the screw is removed;

[0026] The anti-transfer component 3 includes a conical ring piece 301, a connecting strip 302, and a deformation straight groove 303;

[0027] A plurality of connecting strips 302 are provided, and the plurality of connecting strips 302 are evenly distributed on the top outer side of the conical ring piece 301. The conical ring piece 301 is provided at the inner center position of the mounting hole 2, and the conical ring piece 301 is fixed to the inner wall side surface of the mounting hole 2 through the connecting strips 302;

[0028] The deformation straight groove 303 is opened at the bottom of the conical ring piece 301, and there are multiple deformation straight grooves 303 arranged in an annular distribution. When the screw passes through from the top of the conical ring piece 301 to the bottom of the conical ring piece 301, the bottom of the conical ring piece 301 and the notch of the outer wall of the screw are fitted. When the screw moves outward in the opposite direction, the bottom of the conical ring piece 301 is squeezed to destroy the conical ring piece 301.

[0029] The lower surface of the RFID pallet tag 1 is provided with an adhesive component 4 extending into the inside of the mounting hole 2 and clamped with the anti-transfer component 3. The adhesive component 4 is used to install and fix the RFID pallet tag 1 by means of adhesive, and the anti-transfer component 3 is destroyed when disassembling;

[0030] The adhesive component 4 includes an adhesive bottom sheet 401, a through hole 402, an arc-shaped connecting sheet 403 and a limiting block 404;

[0031] The adhesive film 401 is attached to the lower surface of the RFID pallet tag 1. The outer wall width and length of the adhesive film 401 match the width and length of the RFID pallet tag 1 respectively. The lower surface of the adhesive film 401 is provided with an adhesive layer for bonding and fixing the RFID pallet tag 1.

[0032] The through holes 402 are provided at the four corners of the adhesive bottom film 401 and correspond to the positions of the mounting holes 2 one by one, and are used for screws to pass through;

[0033] There are multiple arc-shaped connecting pieces 403 arranged in a ring shape with the through hole 402 as the center. The top of the arc-shaped connecting piece 403 extends to the inner side of the mounting hole 2 and passes through the middle of the two connecting strips 302 to the top of the connecting strip 302. The limiting block 404 is fixed to the top of the arc-shaped connecting piece 403 and fits with the top of the two connecting strips 302.

[0034] In this embodiment, when installing the RFID pallet tag 1, it is possible to choose to fix it by screws or glue, wherein the screw fixing operation is as follows:

[0035] The RFID pallet tag 1 is attached as a whole to the position to be installed, and then the screw is inserted from the installation hole 2. The screw passes through the middle of the conical ring piece 301, the through hole 402 and contacts the surface of the installation position. Then the screw is tightened to drill into the installation position. Finally, the top cap of the screw is attached to the upper surface of the plurality of limit blocks 404, so that the RFID pallet tag 1 is fixed.

[0036] During the above fixing process, the screw will squeeze the bottom of the conical ring piece 301 to deform (it should be noted that the setting of the deformation straight groove 303 makes the bottom of the conical ring piece 301 have good deformation and reset performance). When the screw is finally fixed, the bottom edge of the conical ring piece 301 will be stuck in the spiral groove of the screw. When the screw is reversed to disassemble it, the screw will move to the outside of the installation position. At this time, the spiral part of the screw will form a thrust on the bottom of the conical ring piece 301, and the bottom of the conical ring piece 301 will be deformed. At the same time, the squeezing force will be transmitted to the connecting strip 302, and the deformation of the bottom of the conical ring piece 301 at this time is toward the center of the conical ring piece 301 The screw cannot separate from the conical ring piece 301, and then the screw will break the connecting strip 302 when it moves, so that the anti-transfer component 3 is separated from the RFID pallet tag 1 as a whole. At the same time, as the four anti-transfer components 3 are separated, the adhesive component 4 and the RFID pallet tag 1 also lose the limiting connection force. In this state, the RFID pallet tag 1 cannot be fixed by the adhesive component 4 during the secondary installation. If the RFID pallet tag is installed for the second time by screws, the top cap of the screw has no limit and cannot form a limiting fixing force on the RFID pallet tag 1, that is, the RFID pallet tag 1 cannot be installed for the second time.

[0037] When the RFID pallet tag 1 is installed for the first time, it is only necessary to remove the release paper on the adhesive layer of the adhesive film 2, and then fix the RFID pallet tag 1 at the installation position through the adhesive layer. Under this installation method, if the RFID pallet tag 1 is disassembled and the RFID pallet tag 1 is buckled outward, since the adhesive film 2 is fixed by the adhesive layer, a relative displacement will occur between the RFID pallet tag 1 and the adhesive film 2, that is, the connecting strip 302 will be squeezed with the outward clamping block 404, and the connecting strip 302 will be broken, so that the anti-transfer component 3 is damaged and falls off, and it is impossible to perform a second installation afterwards;

[0038] By cooperating with the above-mentioned multiple parts, it can be achieved that after the RFID pallet tag 1 is initially installed, the anti-transfer component 3 will fall off during disassembly, thereby making it impossible to perform a second installation of the RFID pallet tag 1, thereby effectively avoiding the transfer.

[0039] Please refer to Figures 1 to 3 , the number of connecting strips 302 is twice the number of limiting blocks 404, and the connecting force between the arc-shaped connecting piece 403 and the limiting block 404 and the adhesive bottom film 401 is greater than the connecting force between the connecting strip 302 and the conical ring piece 301 and the inner wall of the mounting hole 2;

[0040] The inner wall diameter of the mounting hole 2 matches the outer diameter of the top cap of the screw, the top inner diameter of the conical ring piece 301 is larger than the outer diameter of the screw part of the screw, and the bottom inner diameter of the conical ring piece 301 is smaller than the outer diameter of the screw part of the screw;

[0041] The top and two side surfaces of the limiting block 404 are in an arc structure, and the bottom of the limiting block 404 is in a flat structure.

[0042] In this embodiment: when the adhesive component 4 is assembled with the RFID tray tag 1, the arc surface structure on the top of the limit block 404 contacts and squeezes the connecting strip 302, and the connecting strip 302 is deformed, so that the limit block 404 can smoothly pass through the middle of the two connecting strips 302, and then the connecting strip 302 is reset to fit the bottom plane of the limit block 404. In this way, when the connecting strip 302 and the limit block 404 are relatively squeezed, the connecting strip 302 cannot be separated from the limit block 404, and the connecting strip 302 can only be broken;

[0043] By matching the inner wall diameter of the mounting hole 2 with the outer diameter of the screw cap, there is no limiting force between the screw cap and the mounting hole 2, that is, when the anti-transfer component 3 falls off, the screw cannot fix the RFID pallet tag 1.

[0044] Please refer to Figures 2-3 The outer sides of the multiple arc-shaped connecting pieces 403 are tightly fitted with the inner wall of the mounting hole 2 , and the inner diameter of the distribution track of the multiple arc-shaped connecting pieces 403 is larger than the bottom outer diameter of the conical ring piece 301 .

[0045] In this embodiment, the outer sides of the plurality of arc-shaped connecting pieces 403 are closely fitted to the inner wall of the mounting hole 2, so that the adhesive component 4 and the RFID pallet tag 1 are kept relatively fixed and will not become loose.

[0046] The inner diameter of the distribution track of the plurality of arc-shaped connecting pieces 403 is larger than the bottom outer diameter of the conical ring piece 301 , so that the arc-shaped connecting pieces 403 will not interfere with the bottom deformation of the conical ring piece 301 .

[0047] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
