[0023] Example

[0024] See also Figure 1 - Figure 5 , the utility model provides a technical solution:

[0025] The LED display screen device includes a fixing box 1, wherein a protective fixing component 4 is arranged inside the fixing box 1, and the protective fixing component 4 includes a screw rod 401, which is rotatably connected to the first end inside the fixing box 1, and a lifting block 403 is threadedly installed on the bottom of the outside of the screw rod 401, and a mounting plate 404 is fixedly installed on the second end of the lifting block 403, and a display screen body 407 is fixedly installed on the second end of the mounting plate 404, and a motor 402 is fixedly installed on the top of the first end of the fixing box 1, and the bottom output end of the motor 402 passes through the fixing box 1 and is fixedly connected to the screw rod 401, and a rotating plate 405 is rotatably installed on the bottom of the second end inside the fixing box 1, and a protective foam 406 is fixedly installed on the first end of the top of the rotating plate 405, and a magnet 408 is fixedly installed on the second end of the top of the rotating plate 405.

[0026] In this embodiment, when shrinkage protection is required, the motor 402 is turned on to drive the screw rod 401 to rotate. When the screw rod 401 rotates, it will drive the lifting block 403 to lift and lower. The lifting block 403 will drive the display screen body 407 to lift and lower through the mounting plate 404. This can facilitate the display and storage of the display screen body 407. When the display screen body 407 descends into the fixed box 1, the bottom of the mounting plate 404 will contact the bottom of the rotating plate 405, driving the rotating plate 405 to rotate at the bottom of the second end of the fixed box 1. The rotating plate 405 will drive the protective foam 406 to be stuck at the second end of the display screen body 407. In this way, when the fixed box 1 is hit from the outside, the display screen body 407 can be prevented from shaking inside the fixed box 1, thereby preventing the display screen body 407 from being damaged by shaking.

[0027] Among them reference Figure 1 - Figure 5 It can be known that rotating teeth 409 are rotatably installed in the middle of both sides inside the fixed box 1, and both sides of the second end of the mounting plate 404 are meshed with the rotating teeth 409, and lifting plates 410 are slidably installed on both sides of the fixed box 1, and the first end of the lifting plate 410 is meshed with the rotating teeth 409, and a pressing block 411 is fixedly installed on the bottom of the lifting plate 410, and external blocks 412 are fixedly installed on the bottom of both sides of the fixed box 1, and rotating support frames 413 are rotatably installed at both ends of the external blocks 412, and fixed blocks 414 are fixedly installed on both sides of both ends of the fixed box 1, and a connecting plate 415 is fixedly installed on the first side of the rotating support frame 413, and a spring 416 is fixedly installed between the connecting plate 415 and the fixed block 414, and universal wheels 2 are fixedly installed at the four top corners of the bottom of the fixed box 1, and a push rod 3 is fixedly installed at the first end of the top of the fixed box 1.

[0028] When the pressing block 411 rises, the spring 416 fixedly installed between the connecting plate 415 and the fixing block 414 drives the rotating support frame 413 to rotate upward to avoid obstruction of movement.

[0029] Working principle: by turning on the motor 402, the screw rod 401 is driven to rotate. When the screw rod 401 rotates, it will drive the lifting block 403 to lift. The lifting block 403 will drive the display screen body 407 to lift through the mounting plate 404. This makes it convenient to display and store the display screen body 407. When the display screen body 407 descends into the fixed box 1, the bottom of the mounting plate 404 will contact the bottom of the rotating plate 405, driving the rotating plate 405 to rotate at the bottom of the second end of the fixed box 1. The rotating plate 405 will drive the protective foam 406 to be stuck at the second end of the display screen body 407. In this way, when the outside of the fixed box 1 is hit, the display screen body 407 can be prevented from shaking inside the fixed box 1, and the shaking of the display screen body 407 can be avoided. When the pressing block 411 rises, the spring 416 fixedly installed between the connecting plate 415 and the fixed block 414 will drive the rotating support frame 413 to rotate upward to avoid obstruction of movement.
