Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-4 In this embodiment: an adjustable electronic class sign display device includes a base plate 1. An adjustment groove 11 is formed on the front of the base plate 1. An adjustment block 12 is slidably installed inside the adjustment groove 11. An electronic class sign display screen 2 is fixedly installed on the front of the adjustment block 12. An adjustment screw 13, threaded into the adjustment block 12, is rotatably installed inside the adjustment groove 11. A motor is fixedly installed inside the base plate 1 and below the adjustment groove 11. The output end of the motor is fixedly connected to the bottom end of the adjustment screw 13. A starting groove 14 is formed on the lower part of the front of the base plate 1. An adjustment switch 6, which is electrically connected to the motor, is installed on the inner side of the groove 14. When in use, by pressing the adjustment switch 6, the motor starts and drives the adjustment screw 13 to rotate, which in turn drives the adjustment block 12 to move up and down in the adjustment groove 11, thereby adjusting the height of the electronic class sign display screen 2. This allows people of different heights to operate the electronic class sign display screen 2. Moreover, the adjustment switch 6 is located in the lower part of the equipment, which is lower than the adjustable height of the electronic class sign display screen 2, making it convenient for people of different heights to press and use, thus improving the practicality and applicability of the equipment.

[0022] In a preferred embodiment, the front of the adjustment block 12 extends to the outside of the adjustment groove 11, and the electronic class sign display screen 2 does not contact the base plate 1, thus ensuring the stability of the electronic class sign display screen 2 during the lifting process.

[0023] In a preferred embodiment, a side groove 15 is provided on the front of the base plate 1 and on the side of the adjustment groove 11. A movable rod 4 is slidably installed on the inner side of the side groove 15. Magnets 43 are fixedly installed at equal intervals from top to bottom on the front of the movable rod 4. The back of the electronic class sign display screen 2 is made of metal. When the electronic class sign display screen 2 is in a fixed position, the movable rod 4 slides back and forth in the side groove 15, which can drive the magnets 43 to contact the back of the electronic class sign display screen 2 and be attracted to the back of the electronic class sign display screen 2. This can help the adjustment block 12 to distribute the weight of the electronic class sign display screen 2 and avoid the adjustment block 12 and the adjustment screw 13 always bearing the weight of the electronic class sign display screen 2, which would affect its service life. This design can reduce the pressure of the adjustment block 12 on the adjustment screw 13 and improve the service life of the equipment.

[0024] Example 2

[0025] Please see Figure 1-4 In this embodiment: the side groove 15 and the starting groove 14 are located on the same vertical plane. A push block 3 is slidably installed on the inner side of the starting groove 14. A connecting groove 5 is opened between the side groove 15 and the starting groove 14. The push block 3 passes through the connecting groove 5 and enters the interior of the side groove 15 and abuts against the movable rod 4. By pushing the push block 3 into the side groove 15, the movable rod 4 can be pushed and made to slide in the side groove 15, thereby driving the magnetic block 43 to be attracted to the back of the electronic class sign display screen 2.

[0026] In a preferred embodiment, the upper section of the push block 3 extends to the inner side of the side groove 15 and has a first inclined surface 31. The lower section of the movable rod 4 has a second inclined surface 41 on its back. The first inclined surface 31 and the second inclined surface 41 abut against each other. The movable rod 4 and the inner side of the side groove 15 are fixedly installed with equally spaced return springs 42. The elastic force of the return springs 42 is greater than the magnetic attraction force of the magnetic block 43. With this design, when the push block 3 moves upward, it pushes the movable rod 4 closer to the electronic class sign display screen 2. When the push block 3 moves downward and disengages from the movable rod 4, the movable rod 4 will reset under the action of the return springs 42, and the magnetic block 43 will disengage from the electronic class sign display screen 2, which facilitates the position adjustment of the electronic class sign display screen 2.

[0027] In a preferred embodiment, a toggle block 7 is fixedly installed on the front of the push block 3 and inside the starting groove 14. The toggle block 7 covers the surface of the adjustment switch 6. When the electronic class sign display screen 2 is not in position, the toggle block 7 covers the surface of the adjustment switch 6 to prevent students or other personnel from accidentally touching the adjustment switch 6 and causing the electronic class sign display screen 2 to be adjusted without cause, thus protecting the electronic class sign display screen 2. The push block 3 abuts against the movable rod 4, and the magnetic block 43 is attracted to the back of the electronic class sign display screen 2. When it is necessary to adjust the height of the electronic class sign display screen 2, the toggle block 7 is pushed down, so that the toggle block 7 is away from the adjustment switch 6, the adjustment switch 6 is exposed, and the magnetic block 43 is disengaged from the electronic class sign display screen 2, which facilitates the adjustment of the position of the electronic class sign display screen 2.

[0028] The working principle and usage process of this utility model are as follows: During use, pressing the adjustment switch 6 starts the motor, causing the adjustment screw 13 to rotate. This, in turn, causes the adjustment block 12 to move up and down reciprocally within the adjustment groove 11, thus adjusting the height of the electronic class sign display screen 2. This accommodates users of different heights. Furthermore, the adjustment switch 6 is located at the lower part of the device, lower than the adjustable height of the electronic class sign display screen 2, making it convenient for users of different heights to press and use, improving the practicality and applicability of the device. With the electronic class sign display screen 2 in a fixed position, pushing the push block 3 into the side groove 15 pushes the movable rod 4. The movable rod 4 slides back and forth within the side groove 15, causing the magnetic block 43 to contact the back of the electronic class sign display screen 2. This allows the magnetic block 43 to adhere to the back of the electronic class sign display screen 2, helping the adjustment block 12 to distribute the weight of the electronic class sign display screen 2. This prevents the adjustment block 12 and the adjustment screw 13 from constantly bearing the weight of the electronic class sign display screen 2, thus affecting its service life. This design reduces the pressure of the adjustment block 12 on the adjustment screw 13, improving the service life of the device.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
