A drive motor 35 is fixedly mounted on the support plate 31 , and an output end of the drive motor 35 is coaxially fixedly connected to the gear 34 .

[0023] Here, the number of the moving blocks 36 is four, and the racks 362 on a group of moving blocks 36 arranged diagonally in the mounting cavity of the support plate 31 are located on the same surface, and the group of racks 362 are staggered on both sides of the gear 34; Among them, a mounting tube 32 is provided in the mounting cavity of the support plate 31, a power button 33 is coaxially provided in the mounting tube 32, a pressure sensor is provided in the mounting tube 32, a spring is provided between the power button 33 and the mounting tube 32, and the pressure sensor is connected to the control board by electrical signals; Usage process: The output end driving gear 34 of the driving motor 35 is synchronously meshed with the racks 362 on the moving blocks 36 at the four corners of the supporting plate 31. When the output end driving gear 34 of the driving motor 35 rotates clockwise, the multiple racks 362 meshing with the gear 34 push the multiple moving blocks 36 to retract into the supporting plate 31. At this time, the multiple right-angle support members 363 at the four corners of the supporting plate 31 automatically position and clamp the small display unit 4. When it is necessary to disassemble the small display screen unit 4, the staff disconnects the control panel from the power button 33 on the control panel, holds the small display screen unit 4, and drives the gear 34 to rotate counterclockwise through the output end of the drive motor 35. At the same time, the multiple racks 362 meshing with the gear 34 push the multiple moving blocks 36 away from the supporting plate 31, so as to loosen the small display screen unit 4; no bolt installation is required, thereby avoiding the risk of damage to the small display screen unit 4 caused by the use of tools during the installation and disassembly of the small display screen unit 4; at the same time, there is no need for multiple employees to perform auxiliary operations, and a single employee can perform splicing operations independently, which improves the splicing and subsequent disassembly efficiency of the display screen compared with the existing technology, and the operation is simple and convenient.

[0024] From the above, we can see that the working principle of this application is as follows: When splicing the small display screen unit 4, the lock 12 between the display screen box door 11 and the display screen housing 1 is opened, and the display screen box door 11 is opened by a group of first hydraulic push rods 14. When installing the small display screen unit 4, the power-on button 33 is pressed, so that after the control panel receives the electrical signal of the pressing sensor in the installation tube 32, the output end of the driving motor 35 is controlled to work, and the bottom of the small display screen unit 4 is placed on a pair of right-angle support members 363 on the bottom end of the supporting plate 31, and the small display screen unit 4 is automatically positioned and clamped by the positioning assembly 3; Then, the output end driving gear 34 of the driving motor 35 is synchronously meshed with the racks 362 on the moving blocks 36 at the four corners of the supporting plate 31. When the output end driving gear 34 of the driving motor 35 rotates clockwise, the multiple racks 362 meshing with the gear 34 push the multiple moving blocks 36 to retract into the supporting plate 31. At this time, the multiple right-angle support members 363 at the four corners of the supporting plate 31 automatically position and clamp the small display unit 4. When it is necessary to disassemble the small display unit 4, the staff disconnects the control panel from the power button 33 on the control panel, holds the small display unit 4, and drives the gear 34 to rotate counterclockwise through the output end of the drive motor 35. At the same time, the multiple racks 362 meshing with the gear 34 push the multiple moving blocks 36 away from the supporting plate 31, so as to loosen the small display unit 4. No bolt installation is required, so that the risk of damage to the small display unit 4 caused by the use of tools during the installation and disassembly of the small display unit 4 is avoided. At the same time, multiple employees are not required to perform auxiliary operations, and a single employee can perform splicing operations independently. The fixing frame 21 is set in a square shape, and each mounting portion 2 is numbered and controlled by the control panel, and the mounting portion 2 located in the middle of the display housing 1 remains stationary, while the mounting portions 2 located in the rest of the display housing 1 are symmetrically arranged in the left and right directions. By setting parameters in advance on the control panel, the output end of the second hydraulic push rod 24 is controlled by the control panel to push the connecting rod 1 22; Since a pulley 221 is provided on one end of the connecting rod 1 22 away from the connecting rod 23, and a guide hole 251 is provided on the connecting frame 25, the pulley 221 is arranged in the guide hole 251; and a connecting rod 26 is provided between the connecting frame 25 and the fixing frame 21, and one end of the connecting rod 26 is rotatably connected to the connecting frame 25, and the pulley 221 at the other end is arranged in the guide hole 1 211 on the fixing frame 21, the stability of the structure of the mounting portion 2 is further ensured; Therefore, the connecting rod 22 is pushed by the output end of the second hydraulic push rod 24 to adjust the angle of the small display screen unit 4 that is positioned and clamped. Through parameter control, the installed multiple small display screen units 4 can be spliced ​​into a large display screen with a curved surface to achieve different video presentation effects, which is convenient for film and television display.

[0025] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
