The moving block 11 between the rotating frames 9 has a sliding inclined groove 13 at the bottom of the moving block 11, and a sliding inclined block 14 is connected to the top of the lifting column 5. The sliding inclined block 14 is slidably connected to the inside of the sliding inclined groove 13. By setting the lifting column 5, when it is necessary to move the bottom box 1 and the display screen 2, the lifting motor 7 is started to drive the first bevel gear 8 to rotate, and then the threaded rod 10 is driven to rotate through the second bevel gear 12, so that the moving block 11 moves, and then the sliding inclined block 14 moves inside the sliding inclined groove 13, and pushes the lifting column 5 to move downward inside the guide sleeve 4, so that the moving wheel 6 contacts the ground. As the lifting column 5 moves downward, the moving wheel 6 and the lifting column 5 prop up the bottom box 1, so that the supporting foot 3 is separated from the ground, which is convenient for movement.

[0023] The four guide sleeves 4 are evenly distributed at the bottom of the bottom box 1 with the lifting motor 7 as the center. The guide sleeves 4 are arranged so as to coincide with the center lines of the rotating frames 9 on both sides and the lifting motor 7. The bottom of the guide sleeves 4 is flush with the bottom of the bottom box 1. The inner wall of the guide sleeves 4 is integrally connected with a limiting protrusion 15. The outer peripheral surface of the lifting column 5 is provided with a limiting slide groove 16 corresponding to the limiting protrusion 15. The limiting protrusion 15 is internally slidably connected to the limiting slide groove 16.

[0024] The bottom of the moving block 11 on one side close to the lifting motor 7 is lower than the bottom of the other side. The sliding inclined groove 13 is opened on the inclined surface at the bottom of the moving block 11. The length of the moving block 11 is half of the distance between the two rotating frames 9. The angle between adjacent threaded rods 10 is ninety degrees. The threaded rods 10 and the upper half of the moving block 11 are threadedly connected. By setting the rotating frame 9, when the threaded rod 10 rotates, the moving block 11 moves. As the distance between the top of the moving lifting column 5 of the moving block 11 and the threaded rod 10 increases, the bottom box 1 is driven to rise through the threaded rod 10, the moving block 11 and the rotating frame 9, so that the moving wheel 6 provides support for the bottom box 1, and the bottom box 1 rises smoothly while facilitating movement.

[0025] The height of the moving wheel 6 is smaller than the height of the supporting foot 3. The moving wheel 6 is a universal wheel. The maximum diameter of the rotating range of the moving wheel 6 is smaller than the diameter of the lifting column 5. A non-slip rubber pad is fixedly installed at the bottom of the supporting foot 3, and the outside of the roller of the moving wheel 6 is wrapped with a wear-resistant rubber layer.

[0026] Working principle:

[0027] When the bottom box 1 and the display screen 2 need to be moved, the lifting motor 7 is started to drive the first bevel gear 8 to rotate, and then the threaded rod 10 is driven to rotate through the second bevel gear 12, so that the moving block 11 moves, and then the sliding bevel block 14 moves inside the sliding bevel groove 13, and pushes the lifting column 5 to move downward inside the guide sleeve 4. As the moving block 11 moves, the distance between the top of the lifting column 5 and the threaded rod 10 increases, and then the bottom box 1 is driven to rise through the threaded rod 10, the moving block 11 and the rotating frame 9, so that the moving wheel 6 contacts the ground. As the lifting column 5 moves downward, the moving wheel 6 and the lifting column 5 prop up the bottom box 1, so that the supporting foot 3 is separated from the ground, which is convenient for movement.
