[0023] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0024] This application discloses a waterproof RFID electronic tag. For example... Figure 1-4 As shown, the device includes a housing 1, with two guide grooves 2 on the upper side of the housing 1. The inner walls of the two guide grooves 2 are slidably and elastically fitted with two moving blocks 3. The upper sides of the multiple moving blocks 3 are fixedly connected to two waterproof plates 4, and the lower sides of the waterproof plates 4 and the upper sides of the housing 1 abut against each other.

[0025] Please see Figure 2 Both sides of the inner wall of the two guide grooves 2 are fixedly connected with top pressure springs 15. The other end of the top pressure springs 15 is fixedly connected to one side of the moving block 3. When there is no external force, the top pressure springs 15 can press the corresponding moving block 3, so that the waterproof plates 4 are tightly fitted together and the lower side of the waterproof plates 4 is fitted together with the outer shell 1, thereby sealing the outer shell 1.

[0026] Please see Figure 2 The inner walls of the two guide grooves 2 are fixedly connected with limit rods 16, and multiple moving blocks 3 are slidably engaged on the outside of the two limit rods 16. When the moving blocks 3 slide, they are guided by the limit rods 16 to increase the stability of the moving blocks 3 when sliding.

[0027] Please see Figure 1 A sealing strip 19 is fixedly connected to the adjacent side of each of the two waterproof membranes 4. The adjacent sides of the two sealing strips 19 abut against each other. When the two waterproof membranes 4 abut against each other, the corresponding sealing strip 19 is between the two and can seal the connection between the two.

[0028] Two guide rods 5 are fixedly connected to the lower side of the inner wall of the outer casing 1. A mounting plate 6 is slidably fitted on the two guide rods 5. Two tension springs 7 are fixedly connected to the lower side of the mounting plate 6. The lower end of the tension springs 7 is fixedly connected to the lower side of the inner wall of the outer casing 1. An electronic tag body 8 is provided on the upper side of the mounting plate 6. A push block 9 is provided on one side of each of the two waterproof plates 4. An L-shaped actuating plate 10 is fixedly connected to the lower side of each of the two waterproof plates 4. Two inclined blocks 11 that cooperate with the L-shaped actuating plate 10 are fixedly connected to the lower side of the mounting plate 6. Some parts of the outer casing 1 are provided with limit components 12.

[0029] Please see Figure 1 The limiting component 12 includes a movable groove 121 formed on one side of the outer casing 1, a movable block 122 slidably fitted on the inner wall of the movable groove 121, a spring piece 123 fixedly connected to the movable block 122 and the inner wall of the movable groove 121, and two limiting plates 124 fixedly connected to one side of the movable block 122. The two limiting plates 124 cooperate with the two pushing blocks 9. By pressing the two pushing blocks 9, the two pushing blocks 9 overlap between the limiting plates 124. By pressing with the spring piece 123, the two pushing blocks 9 can be restricted, so that the electronic tag body 8 can be exposed from the outer casing 1. This not only increases the space for subsequent maintenance but also improves the convenience of subsequent maintenance and replacement of the electronic tag body 8.

[0030] Please see Figure 1 The movable block 122 has a rotating opening 17 on one side. The inner wall of the rotating opening 17 is fitted with a hanging ear 18. By rotating the hanging ear 18 in the rotating opening 17, the hanging ear 18 can be hooked and stored in the corresponding storage position.

[0031] Please see Figure 2 Two fixing plates 13 are fixedly connected to one side of the electronic tag body 8. The two fixing plates 13 are provided with screws 14 that cooperate with the mounting plate 6. The fixing plates 13 are connected to the mounting plate 6 by the screws 14. When disassembling the electronic tag body 8, the electronic tag body 8 can be disassembled by turning the screws 14, which improves the convenience of subsequent replacement.

[0032] Please see Figure 4A rotating groove 20 is provided on one side of the inner wall of the L-shaped actuating plate 10. The inner wall of the rotating groove 20 is fitted with a roller 21 that can rotate. When the L-shaped actuating plate 10 contacts and actuates the inclined block 11, the roller 21 rolls in the rotating groove 20, which can reduce the friction generated during actuation and improve the smoothness of use.

[0033] The implementation principle of a waterproof RFID electronic tag in this application embodiment is as follows: When in use, the top pressure spring 15 squeezes the moving block 3 to drive the corresponding waterproof plate 4 to protect the upper side of the outer shell 1, so that it will not be eroded by rainwater when used outdoors in rainy weather, thus achieving a waterproof effect.

[0034] When swiping the card, the two waterproof plates 4 can be pushed by pressing the corresponding push block 9 with two fingers, so that the two waterproof plates 4 can be unfolded. At the same time, the two L-shaped toggle plates 10 are moved in the corresponding directions, and the inclined block 11 is pushed so that the mounting plate 6 is moved to one side, so that the electronic tag body 8 can be displayed from the shell 1 for use. In this way, while being waterproof, the interference to the signal can be minimized, thereby improving the stability when using the electronic tag body 8.

[0035] When maintenance is required, the two push blocks 9 are pressed to overlap between the limiting plates 124. The spring sheet 123 presses down to restrict the two push blocks 9, allowing the electronic tag body 8 to be exposed from the outer shell 1. This not only increases the space for subsequent maintenance but also improves the convenience of replacing the electronic tag body 8.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
