[0021] See Figures 1-5 As shown, the liquid crystal display screen with a height adjustment structure in the embodiment of the present utility model includes a protection box 1. An import and export 2 is opened at the upper end of the protection box 1, and a sliding groove 3 is opened inside the bottom end of the protection box 1. A driving motor 4 is fixedly connected to the inner wall of the protection box 1 near the lower end on one side. The output end of the driving motor 4 is connected to a bidirectional screw rod 5. The side of the bidirectional screw rod 5 away from the driving motor 4 is rotationally connected to the inner wall of the protection box 1 through a bearing. Both side walls of the bidirectional screw rod 5 are threadedly connected with screw sleeves 6. The lower ends of the screw sleeves 6 are fixedly connected with sliding rods 7. The lower ends of the sliding rods 7 are slidably connected inside the sliding groove 3. The upper ends of the screw sleeves 6 are rotationally connected with symmetrically arranged first rotating shafts 8. The upper ends of the first rotating shafts 8 are rotationally connected with connecting rods 9. The upper ends of the connecting rods 9 are rotationally connected with second rotating shafts 10. The upper ends of the second rotating shafts 10 are jointly rotationally connected with a support plate 11. The upper end of the support plate 11 is connected with a display 12 through a buckle; an array of elastic telescopic rods 14 is fixedly connected to the side of the import and export 2 close to the screen of the display 12. The output ends of the elastic telescopic rods 14 are jointly fixedly connected with a connecting plate 15. A cleaning soft cloth 16 is pasted on the connecting plate 15 through a magic tape.

[0022] A light-shielding plate 13 is fixedly connected to the top end of the display 12, and the light-shielding plate 13 is larger than the import and export 2, which is beneficial to block the light when the light source shines on the display 12 through the light-shielding plate 13 and prevent the screen from reflecting light and being unviewable.

[0023] Support feet are fixedly connected to the two side corners at the lower end of the protection box 1 symmetrically, which is beneficial to increase the overall support of the protection box 1 through the support feet.

[0024] When the height of the display needs to be adjusted, the drive motor 4 is started through an external power supply. The output end of the drive motor 4 drives the bidirectional screw 5 to rotate through a bearing. When the bidirectional screw 5 rotates, it drives the screw sleeve 6. At this time, the screw sleeve 6 moves stably towards the middle of the bidirectional screw 5 under the sliding limit action of the chute 3 and the slide bar 7. When the screw sleeve 6 moves, it will stably lift the support plate 11 under the rotational connection action of the first rotating shaft 8, the connecting rod 9 and the second rotating shaft 10. The support plate 11 drives the display 12 to rise through the inlet and outlet 2 from inside the protection box 1. At the same time, during the rising process of the display 12, it will abut against the connecting plate 15 pushed by the elastic telescopic rod 14. As the display 12 continues to rise, the cleaning soft cloth 16 on the connecting plate 15 will abut against the screen of the display 12 for cleaning, increasing the cleaning efficiency. At the same time, the protection box 1 increases the protection efficiency when the display 12 is not in use and is stored. The cleaning soft cloth 16 can be disassembled through Velcro for cleaning and reuse.
