In this embodiment, the mounting plate 4 plays the role of installing the lifting mechanism 3.

[0034] Reference Figure 3 The upper limit groove 14 has the same structure as the lower limit groove 6, and the slide plate 5 is slidably connected to the inside of the limiting frame 15. In this embodiment, the upper limit groove 14 and the lower limit groove 6 play a role of limiting, and the slide plate 5 and the limiting frame 15 play a role of preventing shaking.

[0035] Reference Figure 3 and Figure 4 The sliding mounting frame 8 is respectively slidably connected to the inside of the lower limit groove 6 and the upper limit groove 14, the support rod 9 is rotatably connected to the inside of the sliding mounting frame 8, and the sliding nut 11 is fixedly connected to one side of the sliding mounting frame 8. In this embodiment, the sliding mounting frame 8 plays the role of installing the support rod 9, the support rod 9 plays the role of lifting, and the sliding nut 11 plays the role of driving the sliding mounting frame 8 to move.

[0036] Reference Figures 5 to 8The protection mechanism 16 includes a display screen 17 and an installation cavity 18. A mounting block 19 is arranged inside the installation cavity 18. A spiral spring 20 is arranged on one side of the installation block 19. A connecting rod 21 is arranged inside the spiral spring 20. A rotating shaft 22 is arranged at one end of the connecting rod 21. A protective film 23 is arranged on the surface of the rotating shaft 22. A buckle 24 is arranged at one end of the protective film 23. A mounting cylinder 25 is arranged at the bottom of the placement table 2. A reset spring 26 is arranged inside the mounting cylinder 25. A limiting shaft 27 is arranged on the top of the reset spring 26. In this embodiment, the mounting cavity 18 serves to store the protective film.

[0037] Reference Figures 5 to 8 The rotating shaft 22 is rotatably connected to the internal setting of the mounting block 19, the spiral spring 20 is fixedly connected to the connecting rod 21, the end of the connecting rod 21 away from the spiral spring 20 is fixedly connected to the rotating shaft 22, and the limiting shaft 27 is slidably connected to the inside of the buckle 24. In this embodiment, the rotating shaft 22 serves to collect the protective film 23, and the connecting rod 21 serves to connect the spiral spring 20 to the rotating shaft 22.

[0038] The implementation principle of this embodiment is:

[0039] When the height of the placement table 2 needs to be adjusted, the motor 13 starts working to drive the two-way threaded rod 12 to rotate. One end of the two-way threaded rod 12 is set as a counterclockwise thread, and the end away from the counterclockwise thread is set as a clockwise thread. By rotating the two-way threaded rod 12, the sliding nut 11 moves toward each other and drives the sliding mounting frame 8 to slide inside the lower limit groove 6 and the upper limit groove 14. The support rod 9 is equipped with a rotating positioning shaft 10. The support rod 9 is lifted and lowered crosswise to continuously lift the placement table 2 to complete the lifting. When the speech is finished, the motor 13 is used to drive the two-way threaded rod 12 to rotate, the sliding nut 11 moves to both ends of the two-way threaded rod 12, and the slide plate 5 slides inside the limit frame 15. The slide plate 5 stops when it contacts the mounting plate 4 and is lowered. Then, the display screen 17 is closed and the protective film 23 is pulled out from the inside of the mounting cavity 18 by pulling the buckle 24. Finally, the buckle 24 is pushed to the top of the mounting tube 25 and fixed by the limiting shaft 27. The protective film 23 plays a dust-proof role and prevents the display screen 17 from being exposed to the outside for a long time. When the smart podium 1 is used again, the limiting shaft 27 is pressed and the reset spring 26 contracts to disengage the buckle 24 from the limiting shaft 27 and roll the protective film 23 onto the outer surface of the rotating shaft 22 driven by the spiral spring 20, so as to quickly collect and store the protective film 23.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] By adding the upper and lower limit grooves 6 and the lower limit grooves 6, the support rod 9 can be prevented from being misplaced. By the coordinated use of the motor 13, the sliding mounting frame 8 and the two-way threaded rod 12, the support rod 9 can be driven to cross and lift. By the coordinated use of the mounting plate 4 and the limiting frame 15, the placement table 2 can be prevented from shaking during lifting. The motor 13 is used as the power to complete the upgrade, which simplifies the lifting steps. Even people who are not familiar with the operation can use it quickly. By the coordinated use of the volute spring 20, the connecting rod 21 and the rotating shaft 22, the protective film 23 can be quickly collected. By adding the protective film 23, the display screen 17 can be prevented from being exposed to the outside for a long time, and it has a dust-proof effect. The buckle 24 and the limiting shaft 27 are used to fix the protective film 23, which avoids the display screen 17 being exposed to the outside for a long time, which causes the display screen 17 to be dusty or even damaged.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
