[0022] Example
[0023] Please refer to Figure 1 to Figure 2 As shown. This embodiment provides an electronic tag, comprising a first clamping plate 1, a second clamping plate 2, a torsion spring 6, a connecting shaft 5, an RFID tag 11 and a number plate 10; the lower side of the first clamping plate 1 comprises two oppositely arranged connecting rods 3, a connecting shaft 5 is installed between the two connecting rods 3, the lower side of the second clamping plate 2 comprises two oppositely arranged rotating rods 4, the two rotating rods 4 are located inside the two connecting rods 3, the connecting shaft 5 passes through the two rotating rods 4, the torsion spring 6 is sleeved on the connecting shaft 5, one side of the torsion spring 6 is connected to the connecting rod 3, and the other side of the torsion spring 6 is connected to the rotating rod 4; the RFID tag 11 is connected to the number plate 10, and the number plate 10 is detachably connected to the first clamping plate 1.
[0024] In the above implementation, along with the gradual improvement of intelligent management and the continuous updating and upgrading of intelligent information hardware facilities, the application of RFID has rapidly penetrated into various industries and fields. For middle and long-distance running, a simple, accurate and efficient timing system is needed. Due to the characteristics of middle and long-distance running (3km, 5km, 10km, race walking) such as the large number of participants, uneven levels, and long sprint time, manual timing and fully automatic end-point photography cannot meet the requirements of efficient and accurate statistics of competition results. In addition, middle and long-distance running is not repeatable, which requires the timing equipment to accurately and stably record and save the competition result data. The common running timing system on the market at present mainly lays induction antennas under each running track. Athletes wear electronic tags that cooperate with the induction antennas. The running time of athletes can be accurately measured during the running process, thereby ensuring the openness, fairness and justice of the competition. However, athletes hang the electronic tags on their clothes. On the one hand, the electronic tags will swing during the running process, causing the electronic tags to be stuck in the clothes of the athletes, thereby causing the magnetic flux change to become smaller and the measurement error to become larger; on the other hand, the electronic tags will swing during the running process of athletes. After the electronic tags come into contact with the athlete's clothes, the RFID tag 11 is close to the human body, and the signal between the RFID tag 11 and the antenna is easily absorbed by the human body. , thereby causing inaccuracy in timing; in the present application, an electronic tag is composed of a first clamping plate 1, a second clamping plate 2, a torsion spring 6, a connecting shaft 5, an RFID tag 11 and a number plate 10. The first clamping plate 1 is connected to the second clamping plate 2 by the connecting shaft 5, and the second clamping plate 2 can rotate relative to the connecting shaft 5. The first clamping plate 1 and the second clamping plate 2 are clamped to each other under the action of the torsion spring 6. Specifically, the athlete connects his number plate 10 to the first clamping plate 1 (the RFID tag 11 is connected to the number plate 10), and then separates one side of the first clamping plate 1 and the second clamping plate 2, and then places the first clamping plate 1 and the second clamping plate 2 at his own collar. After the athlete withdraws the force, the first clamping plate 1 and the second clamping plate 2 clamp the athlete's collar under the action of the torsion spring 6.
[0025] In this embodiment, the athlete places his or her number tag 10 on the first clamping plate 1, and the first clamping plate 1 and the second clamping plate 2 can clamp the athlete's collar, which effectively avoids the problem of the number tag 10 swinging during the athlete's running, and avoids the problem of the number tag 10 getting stuck in the clothes, thereby causing the magnetic flux change to become smaller and the measurement error to become larger; it also avoids the problem of the RFID tag 11 being close to the human body after the electronic tag contacts the athlete's clothes, and the signal between the RFID tag 11 and the antenna being easily absorbed by the human body, thereby causing the problem of inaccurate timing.
[0026] In some embodiments of the present invention, a fixing bolt is further included. The first clamping plate 1 includes a connecting portion 7. The fixing bolt is detachably connected to the connecting portion 7. The number plate 10 is provided with a connecting port 12 adapted to the fixing bolt.
[0027] In this embodiment, the connecting part 7 has a bolt hole, and the fixing bolt passes through the connecting port 12 of the number plate 10, and then cooperates with the connecting part 7 to be fixed to the connecting part 7, and the number plate 10 is fixed between the connecting part 7 and the fixing bolt; further, one side of the fixing bolt is provided with a limiting portion along the circumferential direction, thereby avoiding the problem of the number plate 10 falling off.
[0028] In some embodiments of the present invention, an arc portion 8 is further included, one side of the arc portion 8 is connected to the first clamping plate 1 , and the other side of the arc portion 8 extends along a side away from the second clamping plate 2 .
[0029] In this embodiment, the arc portion 8 is located on one side of the first splint 1, and the athlete can easily separate the first splint 1 from the second splint 2 through the arc portion 8, thereby avoiding the problem that after the first splint 1 and the second splint 2 are clamped, the gap between the first splint 1 and the second splint 2 is small, making it inconvenient for the athlete to separate them.
[0030] In some embodiments of the present invention, the inner side wall of the first clamping plate 1 is provided with an anti-slip layer, and the inner side wall of the second clamping plate 2 is provided with an anti-slip layer.
[0031] In this embodiment, the first clamping plate 1 and the second clamping plate 2 clamp the athlete's collar, and the inner walls of the first clamping plate 1 and the second clamping plate 2 are provided with an anti-slip layer, which increases the friction between them and the athlete's collar, thereby preventing the problem of the electronic tag falling off the athlete's clothing.
[0032] In some embodiments of the present invention, a limiting groove 9 is provided on the inner side wall of the second clamping plate 2 , and a limiting block adapted to the limiting groove 9 is installed on the inner side wall of the first clamping plate 1 .
[0033] In this embodiment, after the first splint 1 and the second splint 2 are clamped, the limit block of the first splint 1 can be sunk into the limit groove 9 of the second splint 2. After the first splint 1 and the second splint 2 clamp the athlete's collar, the athlete's collar can be placed in the limit groove 9 and then fixed by the limit block, thereby improving the stability between the electronic tag and the sports collar and preventing the problem of the electronic tag falling off.
[0034] In some embodiments of the present invention, the RFID tag 11 is connected to the number plate 10 by pasting.
[0035] In this embodiment, the RFID tag 11 and the number plate 10 are connected by gluing, which can be easily installed and removed.

[0037] In this embodiment, the RFID tag 11 is composed of an RFID chip and an RFID antenna. The RFID tag 11 performs identification, and the RFID antenna transmits data.
[0038] In summary, an embodiment of the utility model provides an electronic tag, including a first clamping plate 1, a second clamping plate 2, a torsion spring 6, a connecting shaft 5, an RFID tag 11 and a number plate 10; the lower side of the first clamping plate 1 includes two relatively arranged connecting rods 3, and a connecting shaft 5 is installed between the two connecting rods 3, and the lower side of the second clamping plate 2 includes two relatively arranged rotating rods 4, the two rotating rods 4 are located on the inner sides of the two connecting rods 3, the connecting shaft 5 passes through the two rotating rods 4, the torsion spring 6 is sleeved on the connecting shaft 5, one side of the torsion spring 6 is connected to the connecting rod 3, and the other side of the torsion spring 6 is connected to the rotating rod 4; the RFID tag 11 is connected to the number plate 10, and the number plate 10 is detachably connected to the first clamping plate 1.
