[0040] See also Figure 1 and Figure 6 As shown, there are multiple fixed columns 3 and they are arranged in parallel, the support column 2 is fixedly connected between two adjacent fixed columns 3, the support column 2 is provided with a power connection slot, the display screen 1 is provided with a power connection post, the power connection slot is connected to the power connection post with an electrical signal, and the power connection slot is connected to the power connection post with an electrical signal. Figure 2 As shown, there are multiple mounting columns 11 and they are symmetrically distributed at the four corners of the display screen 1. There are multiple display screens 1. The mounting groove 33 on the same fixed column 3 cooperates with the mounting column 11 on the same side of the display screen 1. An anti-collision groove 12 is coaxially opened on each mounting column 11. An anti-collision member 13 is slidably connected inside the anti-collision groove 12. A spring is arranged in the anti-collision groove 12. One end of the spring is fixedly connected to one end of the anti-collision member 13, and the other end of the spring is fixedly connected to the inner wall of the anti-collision groove 12.

[0041] When in use, when installing the display screen 1, the mounting column 11 of the display screen 1 is aligned with the mounting groove 33 on the fixing column 3. At this time, the limit block 32 is inside the limit groove 31, and the slider 451 blocks the second ventilation hole 35. After placing the display screen 1 in the mounting groove 33, the display screen 1 is pressed to push the piston rod 43, so that the piston rod 43 drives the piston plate 42 to move toward the inside of the air cylinder 41, and the first elastic member 44 is compressed. At the same time, the gas inside the mounting groove 33 is continuously passed through the first ventilation hole 34 and the second ventilation hole 35 into the limiting groove 31, so that the pressure inside the limiting groove 31 is continuously increased. As the mounting column 11 gradually moves, when the pressure inside the limiting groove 31 is greater than the elastic force of the second elastic member 36, the second elastic member 36 is stretched. , so that the limit block 32 moves toward the mounting column 11. As the mounting column 11 continuously drives the piston rod 43 to push the piston plate 42 to move, the gas inside the gas cylinder 41 enters the inside of the slide groove 45 through the third vent hole 411 and the fourth vent hole 453, so that the slider 451 slides upward, so that the third elastic member 452 is compressed. When the mounting column 11 is pressed to the limit position, the slider 451 still blocks the second vent hole 35. The limit block 32 cooperates with the mounting column 11. At this time, the display screen 1 is released, so that the first elastic member 44 relaxes, so that the piston plate 42 pushes the mounting column 11 through the piston rod 43, so that the mounting column 11 moves toward the limit block 32, so that the mounting column 11 is clamped by the piston rod 43 and the limit block 32. When the display screen 1 needs to be removed, the mounting column 11 is pushed by pressing the piston rod 43 so that the mounting column 11 fits with the limiting block 32 to ensure the flatness of the display screen 1 when it is spliced. Through the cooperation between the fixing column 3 and the display screen 1, when any display screen 1 fails and needs to be repaired or replaced, the display screen 1 is pressed again so that the gas inside the cylinder 41 enters the inside of the slide groove 45 through the third vent hole 411 and the fourth vent hole 453, so that the slider 451 slides and the third elastic member 452 is further compressed. When the slider 451 slides to no longer block the second vent hole 35, the gas inside the limiting groove 31 is discharged through the second vent hole 35, so that the second elastic member 36 contracts and drives the limiting block 32 to move toward the limiting groove 3 1 slides inside, when pressed to the limit position, the display screen 1 is released, at this time the first elastic member 44 relaxes to drive the piston rod 43 to push the mounting column 11 to slide to the outside of the mounting groove 33, and when the piston plate 42 moves to the limit position, the piston plate 42 pushes the sealing column 413, so that the sealing column 413 slides inside the sealing groove 412, so that the exhaust pipe 454 is connected with the outside, so that the gas in the slide groove 45 is discharged through the exhaust pipe 454, and the third elastic member 452 relaxes to drive the slider 451 to slide, so that the second vent hole 35 is blocked again. Through the pressing installation method, when the display screen 1 is damaged and needs to be replaced, there is no need to dismantle the entire spliced ​​LED screen, nor is there any need to release the fixing device multiple times, and the LED screen can be freely replaced and removed.

[0042] Example 2

[0043] It is found in actual use that when pressing, if the pressing force is too large, the display screen 1 is easily damaged. Further improvements are made on the basis of the above embodiment.

[0044] On the basis of the above embodiment, when the display screen 1 is installed, when the mounting post 11 is placed in the mounting groove 33, the permanent magnet 331 exerts a continuous attraction on the mounting post 11, and the attraction of the permanent magnet 331 is less than the elastic force of the first elastic member 44. At this time, the display screen 1 only needs to be gently pushed to make the mounting post 11 push the piston rod 43. As the mounting post 11 moves into the mounting groove 33, the first elastic member 44 is compressed, and the reaction force on the mounting post 11 gradually increases. However, since the distance between the mounting post 11 and the permanent magnet 331 gradually decreases, the attraction on the mounting post 11 gradually increases, thereby When installing the display screen 1, only a small thrust is needed to complete the installation, preventing the display screen 1 from being damaged due to excessive thrust during installation. When the display screen 1 needs to be removed, the display screen 1 is pressed to move the piston plate 42 to the extreme position, and then the display screen 1 is released. The first elastic member 44 relaxes and drives the piston rod 43 to push the installation column 11. Since the permanent magnet 331 continuously exerts an attractive force on the installation column 11, the installation column 11 slowly slides to the outside of the installation groove 33 at this time, preventing the display screen 1 from falling and being damaged due to the sudden release of the first elastic member 44 when removing the display screen 1.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
