[0023] An RFID device for food traceability includes an RFID device body 1.

[0024] In this embodiment: Although the design can save the trouble of holding, free the staff's hands, and improve the convenience of use, in actual use, when reading some RFID tags that are difficult to access or operate, the staff needs to unfasten the fixing belt 210, then remove the RFID device from the wrist, and then hold the RFID device to read the RFID tag, and then wear the RFID device on the wrist after reading. This is rather cumbersome. In order to solve this technical problem, a disassembly component 2 is added on this basis.

[0025] More specifically:

[0026] like Figures 1 to 4 As shown:

[0027] In combination with the above content: the disassembly component 2 includes a first connecting block 21, a support rod 22, a support ball 23, a first spring 25 and a second spring 28. The first connecting block 21 is fixedly connected to the outer side of one end of the RFID device body 1, and the support rod 22 is slidably connected inside the first connecting block 21. Two support balls 23 are fixedly connected to the outer side of the end of the support rod 22, and a connecting plate 24 is fixedly connected to the outer side of the end of the support rod 22. The outer sides of both ends of the first spring 25 are respectively fixedly connected to the outer side of one end of the connecting plate 24 and the inner side of one end of the first connecting block 21. The first connecting block 21 has a rectangular through groove with a fixed block 27 slidably connected inside, and the first connecting block 21 has a rectangular through groove with a blocking plate 26 fixedly connected inside, and the outer sides of both ends of the second spring 28 are respectively fixedly connected to the inner side of one end of the fixed block 27 and the outer side of one end of the blocking plate 26. The outer side of the end of the first connecting block 21 is detachably connected to the second connecting block 29, and the outer side of one end of the fixed block 27 contacts the inner side of one end of the second connecting block 29. The lower surface of the second connecting block 29 is fixedly connected to a fixing belt 210.

[0028] In this embodiment: In the RFID device, the RFID device body 1 is composed of a reader and a display, the part directly connected to the first connecting block 21 is the display in the RFID device, and the part installed vertically to the display is the reader in the RFID device. The user can read and write relevant data by aligning the reader part of the RFID device body 1 with the RFID tag of the food package for scanning. When using the device, the user passes the hand through the fixing belt 210, and the device can be fixed at the wrist through the fixing belt 210. The first connecting block 21 is fixedly connected to the outer side of one end of the RFID device body 1, and a trapezoidal structure is arranged on the outer side of the end of the first connecting block 21, and a second connecting block 21 is fixedly connected to the outer side of the end of the fixing belt 210. The inner side of the end of the block 29 is provided with a trapezoidal groove, and the trapezoidal structure of the first connecting block 21 can slide inside the trapezoidal groove of the second connecting block 29. A circular through groove is opened inside the first connecting block 21, and two supporting balls 23 are fixedly connected to the outer side of one end of the support rod 22. At the same time, a fixed block 27 is slidably connected inside the rectangular through groove inside the end of the first connecting block 21. A wedge-shaped structure is provided on the outer side of the end of the fixed block 27. The outer side of the end of the fixed block 27 contacts the inner wall surface of the trapezoidal groove of the second connecting block 29. When the trapezoidal structure of the first connecting block 21 is inside the trapezoidal groove of the second connecting block 29, under the action of the first spring 25, the supporting ball 23 on the outer surface of the support rod 22 continuously presses against the outer side of one end of the fixed block 27, fixing An arc-shaped groove is provided on the outer side of one end of the block 27, which can better adapt to the shape of the support ball 23, thereby driving the outer side of the other end of the fixed block 27 to continuously press against the inner wall surface of the trapezoidal groove of the second connecting block 29. The columnar structure on the outer side of the end of the support rod 22 can limit the position of the support rod 22, and the RFID device body 1 on the outer side of the end of the first connecting block 21 can be fixed to the second connecting block 29. When the user wants to quickly disassemble the RFID device body 1, the user only needs to press the support rod 22 to compress the first spring 25 and drive the support rod 22 to slide inside the first connecting block 21. When the support rod 22 slides, the support ball 23 detaches from the outer side of one end of the fixed block 27 and is fixed under the drive of the second spring 28. The card block 27 slides inside the rectangular through groove of the first connecting block 21, so that the outer side of the other end of the fixed card block 27 is separated from the inner wall surface of the trapezoidal groove of the second connecting block 29, so that the fixed card block 27 loses the supporting force on the inner wall surface of the trapezoidal groove of the second connecting block 29, and then the first connecting block 21 can be slid to drive the RFID device body 1 outside the end of the first connecting block 21 to be quickly disassembled. The RFID device body 1 can be quickly disassembled through the support rod 22 and the fixed card block 27. For some RFID tags set in difficult-to-access or operating positions, the user can quickly disassemble the RFID device body 1, and then hold the RFID device body 1 to read the RFID tag, which increases the flexibility and practicality of the device.

[0029] It should be noted that the function of the connecting plate 24 is to connect the supporting rod 22 with the first spring 25 , and the function of the blocking plate 26 is to connect the second spring 28 with the first connecting block 21 .

[0030] Going further:

The first damping strips 211 and the second damping strips 212 are both made of rubber.

[0032] In this embodiment: a plurality of second damping strips 212 are fixedly connected to the outer side of the end of the fixed block 27, and a plurality of first damping strips 211 are fixedly connected to the inner wall of the trapezoidal groove of the second connecting block 29. The second damping strips 212 and the first damping strips 211 can increase the friction between the fixed block 27 and the inner side of the end of the second connecting block 29, so that the RFID device body 1 is fixed more firmly, preventing the first connecting block 21 from accidentally slipping from the inside of the second connecting block 29, thereby increasing the stability of the device.

[0033] Going further:

[0034] In an optional embodiment, a rubber pad 213 is fixedly connected to the lower surface of the second connecting block 29 , and the material of the rubber pad 213 is silicone.

[0035] In the present embodiment: the lower surface of the second connecting block 29 is fixedly connected with a rubber pad 213, and the material of the rubber pad 213 is silicone. When the user wears the device, the rubber pad 213 can prevent the device from directly contacting the user's wrist, thereby reducing the user's discomfort when wearing it, increasing the user's wearing experience, and ensuring that the user can wear the device for a long time to work.

[0036] Going further:

[0037] In an optional embodiment, a rotating plate 214 is rotatably connected to the outer side of one end of the second connecting block 29, a finger ring 215 is provided on the outer side of the end of the rotating plate 214, and a plurality of connecting ropes 216 are fixedly connected to the outer side of one end of the rotating plate 214. The outer side of the end of the connecting rope 216 is fixedly connected to the outer side of one end of the finger ring 215, and the connecting rope 216 is made of elastic material.

[0038] In this embodiment: when the user wears the device, the user can insert the finger into the through hole opened on the inner side of the end of the finger ring 215. The rotating plate 214 and the finger ring 215 can ensure the stability of the device during operation without sliding on the user's wrist, thereby increasing the practicality and stability of the device. At the same time, the rotating plate 214 is rotatably connected to the second connecting block 29 and the elastic connecting rope 216, so that the user can still move at a certain angle after inserting the finger into the finger ring 215, which will not affect the normal operation of the user's hand, further increasing the flexibility of the device.

[0039] Working principle: In the RFID device, the RFID device body 1 is composed of a reader and a display. The part directly connected to the first connecting block 21 is the display in the RFID device, and the part installed vertically to the display is the reader in the RFID device. The user can read and write relevant data by aligning the reader part of the RFID device body 1 with the RFID tag of the food package for scanning. When using the device, the user passes the hand through the fixing belt 210, and the device can be fixed at the wrist through the fixing belt 210. The first connecting block 21 is fixedly connected to the outer side of one end of the RFID device body 1, and a trapezoidal structure is arranged on the outer side of the end of the first connecting block 21. The outer side of the end of the fixing belt 210 is fixedly connected to the second connecting block 2 9, a trapezoidal groove is provided on the inner side of the end portion, and the trapezoidal structure of the first connecting block 21 can slide inside the trapezoidal groove of the second connecting block 29.

At the same time, a fixed clamping block 27 is slidably connected inside the rectangular through groove inside the end portion of the first connecting block 21, and a wedge-shaped structure is provided on the outer side of the end portion of the fixed clamping block 27. The outer side of the end portion of the fixed clamping block 27 contacts the inner wall surface of the trapezoidal groove of the second connecting block 29. When the trapezoidal structure of the first connecting block 21 is inside the trapezoidal groove of the second connecting block 29, under the action of the first spring 25, the supporting ball 23 on the outer surface of the support rod 22 continuously presses against the outer side of one end of the fixed clamping block 27, and the fixed clamping block 27 is fixed. An arc-shaped groove is provided on the outer side of one end of the block 27, which can better adapt to the shape of the support ball 23, thereby driving the outer side of the other end of the fixed card block 27 to continuously press against the inner wall surface of the trapezoidal groove of the second connecting block 29. The columnar structure on the outer side of the end of the support rod 22 can limit the position of the support rod 22, and the RFID device body 1 on the outer side of the end of the first connecting block 21 can be fixed to the second connecting block 29. When the user wants to quickly disassemble the RFID device body 1, the user only needs to press the support rod 22 to compress the first spring 25 and drive the support rod 22 to slide inside the first connecting block 21. When the support rod 22 slides, the support ball 23 detaches from the outer side of one end of the fixed card block 27, and the fixed card is driven by the second spring 28. The block 27 slides inside the rectangular through groove of the first connecting block 21, so that the outer side of the other end of the fixed card block 27 is separated from the inner wall surface of the trapezoidal groove of the second connecting block 29, so that the fixed card block 27 loses the supporting force on the inner wall surface of the trapezoidal groove of the second connecting block 29, and then the first connecting block 21 can be slid to drive the RFID device body 1 outside the end of the first connecting block 21 to be quickly disassembled. The RFID device body 1 is quickly disassembled through the support rod 22 and the fixed card block 27. For some RFID tags set in difficult-to-access or difficult-to-operate positions, the user can quickly disassemble the RFID device body 1, and then hold the RFID device body 1 to read the RFID tag, which increases the flexibility and practicality of the device.A plurality of second damping strips 212 are fixedly connected to the outer side of the end of the fixed card block 27, and a plurality of first damping strips 211 are fixedly connected to the inner wall surface of the trapezoidal groove of the second connecting block 29. The second damping strips 212 and the first damping strips 211 can increase the friction between the fixed card block 27 and the inner side of the end of the second connecting block 29, so that the RFID device body 1 is fixed more firmly, and the first connecting block 21 is prevented from accidentally slipping from the inside of the second connecting block 29, thereby increasing the stability of the device. A rubber pad 213 is fixedly connected to the lower surface of the second connecting block 29. The material of the rubber pad 213 is silicone. When the user wears the device, the rubber pad 213 can prevent the device from directly contacting the user's wrist. The discomfort of the user when wearing the device is reduced, the user's wearing experience is improved, and the user can wear the device for a long time to work.

The stability of the device during work can be ensured by the rotating plate 214 and the finger ring 215, and the device will not slide on the user's wrist, which increases the practicality and stability of the device. At the same time, the rotating plate 214 is rotatably connected with the second connecting block 29 and the elastic connecting rope 216, so that the user can still move at a certain angle after inserting the finger into the finger ring 215, which will not affect the normal work of the user's hand, and further increases the flexibility of the device.
