Example Embodiment
[0027] Example 1
[0028] The display screen with convenient position adjustment includes a polygonal tube 1, a lifting drive mechanism 2 is installed on the polygonal tube 1, a lead screw nut mechanism 3 is connected to the output shaft of the lift drive mechanism 2, and the lead screw nut mechanism 3 is sleeved on the polygonal tube 1. Inside, the other end of the screw nut mechanism 3 is connected with a lifting tube 4, the other end of the lifting tube 4 is connected with a horizontal frame 5, and a rack 51 is arranged on the horizontal frame 5; it also includes a display screen main body 6, the upper end of the display screen main body 6 is The upper frame 61 is connected, the traverse frame 7 is fixed on the upper frame 61, the traverse drive mechanism 8 is installed on the traverse frame 7, and the output shaft of the traverse drive mechanism 8 is connected with a gear 9, and the gear 9 meshes with the rack 51 .

Example Embodiment
[0030] Embodiment 2
[0031] On the basis of the first embodiment, the lead screw nut mechanism 3 includes a lead screw 31, and the lead screw 31 is threadedly connected with a nut 32, the nut 32 is sleeved in the polygonal tube 1, and the other end of the nut 32 is connected to the lifting tube 4; One end of the lead screw 31 is connected with a rotating shaft 33 , the rotating shaft 33 is connected in the polygonal tube 1 through a bearing, and the elevating driving mechanism 2 of the rotating shaft 33 is connected.
[0032] When the lift drive mechanism 2 drives the rotating shaft 33 to rotate, the lead screw 31 rotates accordingly. Since the polygonal tube 1 can restrict the rotation of the nut 32 , the nut 32 will move linearly in the polygonal tube 1 . Therefore, the nut 32 can drive the lifting tube 4 to move, and the display screen main body 6 can rise and fall accordingly.
Example Embodiment
[0033] Embodiment 3
[0034] On the basis of Embodiment 1 or Embodiment 2, the lift driving mechanism 2 includes a lift motor 21 , an output shaft of the lift motor 21 is connected with a lift reducer 22 , and the lift motor 21 and the lift reducer 22 are both fixed to the polygonal tube 1 . On the top, the output shaft of the lift reducer 22 is connected with a driving gear 23 , the driving gear 23 is meshed with a driven gear 24 , and the driven gear 24 is connected with the lead screw nut mechanism 3 .
[0035] The lift motor 21 can drive the lift reducer 22 to operate, the lift reducer 22 drives the driving gear 23 to rotate, and the driven gear 24 drives the screw nut mechanism 3 to operate. The moving direction of the display screen main body 6 can be controlled by controlling the direction of the lift motor 21, and the moving distance of the display screen main body 6 can be precisely controlled by controlling the action time of the lift motor 21, which is convenient fo...
