[0027] Among them, by pressing the push rod 8, the gas inside the airbag 7 enters the inside of the sealing chamber 5, so that the piston block 13 moves, so that the limiting rod 14 can be inserted into the inside of the connecting rod 4, thereby completing the limitation of the LED screen body 3, and then rotating the push rod 8 so that the limiting block 9 and the clamping block 10 are limited to each other to complete the fixing of the LED screen body 3.

[0028] In addition, when disassembling, it is only necessary to rotate the push rod 8 so that the limit block 9 and the clamping block 10 are no longer limited. At this time, part of the gas inside the sealing chamber 5 will return to the airbag 7, thereby resetting the limit rod 14, thereby facilitating the installation and disassembly of the LED screen body 3. The operation process is simple and does not require any tools, which greatly improves the efficiency of maintenance of the LED screen body 3.

[0029] It is worth noting that the flow tube 12 and the inner wall of the mounting block 2 are integrated, and the gas inside the sealed cavity 5 can only enter the interior of the airbag 7 through the flow tube 12 .

[0030] In this embodiment, a connecting groove 15 adapted to the connecting rod 4 is formed on the top of the mounting block 2, and the connecting rod 4 is inserted into the connecting groove 15. A clamping groove is formed on one side of the connecting rod 4, and the limiting rod 14 is adapted to the size of the clamping groove.

[0031] See also Figure 3 In this embodiment, a sealing sleeve 16 is fixedly installed between the sealing cavity 5 and the connecting groove 15 , and the limiting rod 14 is slidably connected to the inner wall of the sealing sleeve 16 .

[0032] The sealing effect of the sealing cavity 5 is ensured by the provided sealing sleeve 16 .

[0033] In this embodiment, a plurality of mounting sleeves 23 are mounted on the surface of the fixing rod 1 , and a mounting cover 17 is fixedly mounted on one side of the mounting sleeve 23 .

[0034] See also Figure 4 and Figure 5In this embodiment, a second adjustment component is provided inside the mounting cover 17, and the second adjustment component includes a screw rod 18 rotatably mounted on the inner wall of the mounting cover 17, one end of the screw rod 18 extends to the outside of the mounting cover 17, and a slide rod 19 is also fixedly mounted on the inner wall of the mounting cover 17, and two moving blocks 20 are threadedly mounted on the surface of the screw rod 18, and the other sides of the two moving blocks 20 are slidably connected to the slide rod 19, and the mounting block 2 is fixedly mounted on the side of the moving block 20 close to the outside of the mounting cover 17.

[0035] When the horizontal positions of the two LED screen bodies 3 need to be adjusted, the screw rod 18 can be rotated to move the two moving blocks 20 in opposite or opposite directions, thereby adjusting the horizontal position between the two LED screen bodies 3 .

[0036] In addition, the threads on the left and right sides of the surface of the screw rod 18 are in opposite directions, and the two moving blocks 20 are respectively threadedly installed on the side of the surface of the screw rod 18 with opposite thread directions.

[0037] See also Figure 7 In this embodiment, a first adjustment component is arranged between the fixing rod 1 and the mounting sleeve 23. The first adjustment component includes a plurality of thread grooves 22 opened on the surface of the fixing rod 1. The surface of the mounting sleeve 23 is threadedly installed with a threaded rod 21 extending into the corresponding thread groove 22. The mounting sleeve 23 is fixedly installed on the outside of the fixing rod 1 through the threaded rod 21.

[0038] When the vertical positions of the two LED screen bodies 3 need to be adjusted, the threaded rod 21 is rotated. When the threaded rod 21 is disengaged from the threaded groove 22, the mounting sleeve 23 is no longer limited, and the position of the mounting sleeve 23 can be adjusted.

[0039] In this way, the vertical position between the two LED screen bodies 3 can be adjusted, thereby making the device convenient for splicing between LED screen bodies 3 of different sizes, greatly improving the applicability of the connecting device.

[0040] It is worth noting that the device can also appropriately increase the number of mounting sleeves 23 on the fixing rod 1, and then increase the number of LED screen bodies 3 as needed, further improving the practicality of the device.

[0041] When the present embodiment is in use, when the LED screen body 3 needs to be installed, the connecting rod 4 on the rear side of the LED screen body 3 is inserted into the corresponding mounting block 2, and the push rod 8 is pressed so that the gas inside the airbag 7 enters the inside of the sealing cavity 5, thereby moving the piston block 13, thereby allowing the limiting rod 14 to be inserted into the inside of the connecting rod 4, thereby completing the limiting of the LED screen body 3, and then rotating the push rod 8 so that the limiting block 9 and the card block 10 are mutually limited to complete the installation of the LED screen body 3; when a single LED screen body 3 needs to be maintained, the push rod 8 is rotated so that the limiting block 9 and the card block 10 are no longer limited, and at this time, part of the gas inside the sealing cavity 5 will return to the inside of the airbag 7, thereby resetting the limiting rod 14, thereby facilitating the disassembly of the LED screen body 3 for maintenance, and the operation process is simple and does not require the use of any tools, thereby greatly improving the efficiency of the maintenance of the LED screen body 3;

[0042] When it is necessary to adjust the horizontal position of the two LED screen bodies 3, rotating the screw rod 18 can make the two moving blocks 20 move in opposite directions, thereby adjusting the horizontal position between the two LED screen bodies 3; when it is necessary to adjust the vertical position of the two LED screen bodies 3, rotate the threaded rod 21. When the threaded rod 21 is disengaged from the threaded groove 22, the mounting sleeve 23 is no longer limited, and the position of the mounting sleeve 23 can be adjusted. Thus, the vertical position between the two LED screen bodies 3 can be adjusted, thereby making the device convenient for splicing between LED screen bodies 3 of different sizes, greatly improving the applicability of the connecting device.
