[0054] In this embodiment, the blocking mechanism includes a lock shaft 37 rotatably connected to the left side of the box body 32, and an intermediate shaft 38 is coaxially fixed to the lock shaft 37 inside the box body 32. The inner end of the intermediate shaft 38 is fixedly provided with a crank arm 39, and the outer end of the crank arm 39 is hinged to a connecting rod 40. The top of the connecting rod 40 is hinged to a guide block 41, and the guide block 41 is sliding up and down between two side plates 42 fixedly connected to the inner wall of the box body 32; a blocking groove 43 is provided at the position corresponding to the pin 33 and the guide block 41; a torsion spring 44 is sleeved on the intermediate shaft 38, one end of the torsion spring 44 is connected to the intermediate shaft 38, and the other end of the torsion spring 44 is connected to the inner wall of the box body 32; the angular orientation words in this paragraph are as follows Figure 17 When in use, the torsion spring 44 drives the intermediate shaft 38 to rotate, and the intermediate shaft 38 drives the crank arm 39 to rotate clockwise. The crank arm 39 drives the guide block 41 to move upward through the connecting rod 40, so that the guide block 41 enters the blocking groove 43 of the pin shaft 33, thereby preventing the pin shaft 33 from moving left and right.

[0055] When the left side frame 5 needs to be opened, the lock shaft 37 is first rotated to drive the intermediate shaft 38 to rotate, and the intermediate shaft 38 drives the crank arm 39 to rotate counterclockwise (with the left side frame 5 opened). Figure 17The crank arm 39 drives the guide block 41 to move downward through the connecting rod 40, so that the guide block 41 disengages from the blocking groove 43, and then the pin shaft 33 is moved axially, so that the rotation-limiting block 34 disengages from the rotation-limiting groove 36.

At this time, the guide block 41 is just aligned with the blocking slot 43 of the pin shaft 33, and the torsion spring 44 drives the guide block 41 to move upward and insert into the blocking slot 43, preventing the pin shaft 33 from moving axially; in actual operation, when the axial movement of the pin shaft 33 causes the rotation-limiting card block 34 to be inserted into the corresponding rotation-limiting card slot 36, the lock shaft 37 can be observed. When the lock shaft 37 rotates, it means that the guide block 41 is inserted into the blocking slot 43, and the operation is completed.

[0056] In order to facilitate the rotation of the lock shaft 37, in this embodiment, a drive groove 45 is provided on the outer end surface of the lock shaft 37, and a drive member 46 is also included.

[0057] When the lock shaft 37 is rotated by the driving member 46, in order to facilitate the confirmation that the guide block 41 is completely disengaged from the blocking groove 43, in this embodiment, a limit block 48 is fixedly provided on the side of the crank arm 39 close to the lock shaft 37, and a blocking block 49 is fixedly provided on the inner side wall of the box body 32. When it is necessary to open the left side frame 5, the lock shaft 37 is first rotated by the driving member 46 to drive the intermediate shaft 38 to rotate, and the intermediate shaft 38 drives the crank arm 39 to rotate counterclockwise (to Figure 17 The crank arm 39 drives the guide block 41 to move downward through the connecting rod 40, so that the guide block 41 disengages from the blocking groove 43. At this time, the limit block 48 rotates with the crank arm 39 and is blocked by the blocking block 49. That is, when the driving member 46 stops rotating, it means that the guide block 41 is completely disengaged from the blocking groove 43. Then the pin shaft 33 is moved axially, so that the rotation limiting block 34 disengages from the rotation limiting groove 36. At this time, the left side frame 5 can be opened. At this time, the guide block 41 is pressed by the outer surface of the pin shaft 33 and remains unchanged in the state after moving downward.

[0058] In this embodiment, two vertical rods 50 are vertically fixed on the side of the upper end surface of the bottom frame 1 close to the left frame 5. The top ends of the two vertical rods 50 are fixed to the top plate 6. The left sides of the two vertical rods 50 are hinged with hydraulic telescopic rods 51, and the output shafts of the hydraulic telescopic rods 51 are hinged to the left frame 5.

[0059] In this embodiment, the LED integrated panels 2 on both sides of the left side frame 5 and the back panels of the left LED integrated panels 2 on the front side frame 3 and the rear side frame 4 are all provided with forty-five degree inclined surfaces; when the left side frame 5 is closed, the inclined surfaces of the back panels of the LED integrated panels 2 fit together and splice together, ensuring seamless splicing of the right-angle display screen.

[0060] In this embodiment, lifting rings are provided at the four corners of the upper end surface of the top plate 6 to facilitate the use of a crane to lift the LED screen.

[0061] The working principle of the present invention is as follows: the bottom frame 1 is connected to the support frame 15 through the first clamping part and the second clamping part, and the cross bar 16 of the support frame 15 is connected to the longitudinal beam 19 of the frame 7 through the connecting piece 18 and bolts, thereby realizing the fixed connection between the LED screen and the frame 7. Driving the car drives the frame 7 to move and thus moves the LED screen. The LED screen on the side frame plays videos to show the surroundings. The played videos can be ordinary videos or videos with 3D effects. The silent gasoline generator 8 in the space formed between the top plate 6, the side frames and the bottom frame 1 starts to generate electricity to supply electricity to the LED screen. The cold air generated by the air-conditioning component is blown into the internal space formed between the top plate 6, the side frames and the bottom frame 1 through the air distribution port 12 of the air distribution block 11 to cool the LED screen and ensure that the LED Normal operation of the screen; the left side frame 5 can be opened to facilitate personnel to enter the internal space formed between the top plate 6, the side frame and the bottom frame 1 to inspect and maintain the silent gasoline generator 8 or the LED screen; when the left side frame 5 needs to be opened, the lock shaft 37 is driven to rotate by the driving member 46 until the driving member 46 can no longer rotate, which means that the guide block 41 is completely disengaged from the blocking groove 43. At this time, the pin shaft 33 is moved axially to allow the rotation limit block 34 to be pulled out of the rotation limit groove 36, and then the left side frame 5 can be opened; when the left side frame 5 needs to be closed, the left side frame 5 is rotated and closed, and then the pin shaft 33 is moved axially to allow the rotation limit block 34 to enter the corresponding rotation limit groove 36. At this time, observe the lock shaft 37. When the lock shaft 37 rotates, it means that the guide block 41 has entered the blocking groove 43, and the operation of closing the left side frame 5 is completed.
