[0024] Figure 1 is a side sectional view of an embodiment of a portable LED display screen of the present invention, Figure 2 is a top view of a bottom plate of a portable LED display screen embodiment of the present invention, Figure 3 This is a bottom view of the top plate of a portable LED display screen of the present invention. Figure 4 This is a side cross-sectional view of a top plate of a portable LED display screen of the present invention. Figure 5 This is a schematic diagram of the connection between the limit slot and the fixed block of a portable LED display screen of the present invention. Figure 6 It is a rear view of a portable LED display screen of the present invention, wherein adjacent LED screens are connected. As shown in the figure, a portable LED display screen comprises a storage box 1, wherein a fixing plate 17 is provided at a fixing groove 18 inside a top plate 13 of the storage box 1, and the fixing plate 17 is provided with a fixing block 16 connected to a limiting groove 15 below the fixing groove 18. The fixing block 16 is connected to a folding motor 4 on the top plate 13, and the two ends of a cover opening motor 3 on the right side of the folding motor 4 are respectively connected to the top plate 13 and the bottom plate of the storage box 1. The guide rail 9 of the bottom plate is connected to a moving seat 8 through a slider 14, and an LED screen 7 is provided above the moving seat 8. The steel wire 11 connected to the LED screen 7 is connected to a take-up motor 5 through a fixing ring 12, and the slider 14 is connected to a push plate motor 2 through a threaded rod 10. The push plate motor 2 pushes the moving seat 8 together with the left side wall out of the storage box 1, the cover opening motor 3 pushes open the top plate 13 of the storage box 1, and the folding motor 4 unfolds the folded LED screen 7. The fixing plate 17 connected to the steel wire 11 is responsible for unfolding or folding the LED screen 7 , and the fixing block 16 connected to the fixing plate 17 is driven by the folding motor 4 so that the fixing plate 17 can move left and right inside the fixing groove 18 .

[0025] The folding LED screen 7 is hinged on the moving seat 8, and the fixing ring 12 is located at the top of the right side wall and the outside of the fixing plate 17. The adjusting motor 20 at the top of the single LED screen 7 is connected to the thick steel wire rope 21, and the positioning sleeve 22 with internal threads at the bottom is connected to one end of the screw rod 23 matched with it, and the thick steel wire rope 21 is connected to the other end of the screw rod 23 on the single LED screen 7 above it. The fixing ring 12 limits the movement trajectory of the steel wire 11, ensuring that the steel wire 11 is orderly retracted and released inside the storage box 1 without interfering with the normal operation of other structures. The fixing ring 12 is located on both sides of the fixing plate 17 and the top of the right side wall, ensuring that the steel wire 11 passing through drives the LED screen 7 to fold or unfold normally. The thick steel wire rope 21 ensures that the LED screen 7 can be folded smoothly. When the LED screen 7 is unfolded, the adjusting motor 20 is started to drive the thick steel wire rope 21 to rotate, and the thick steel wire rope 21 drives the screw rod 23 to rotate inside the positioning sleeve 22, thereby retracting the thick steel wire rope 21, so that the LED screen 7 is connected together.

[0026] The fixing plate 17 matches the inside of the fixing groove 18, and a slide rail 19 is provided between the side wall of the fixing block 16 and the limiting groove 15. The slide rail 19 ensures that the fixing block 17 always moves along the limiting groove 15, and the limiting groove 15 limits the distance that the fixing plate 17 moves out of the fixing groove 18.

[0027] The right part of the slider 14 is connected to the guide rail 9, and the left part thereof is provided with a guide groove matching the threaded rod 10. The push plate motor 2 drives the threaded rod 10 to rotate, and the slider 14 drives the moving seat 8 to move out of the storage box 1 as the threaded rod 10 rotates. The bottom of the left side wall contacts the ground to ensure the stability of the moving seat 8 when it is fixed.

[0028] One end of the cover opening motor 3 is hinged to the bottom plate, and the other end is hinged to the top plate 13, and the top plate 13 is hinged to the right side wall of the storage box 1. The cover opening motor 3 changes its angle as the top plate 13 is opened to ensure that the top plate 13 can be opened smoothly. Two ends of the wire-retracting motor 5 are connected to two sections of steel wire 11, and the steel wire 11 is connected to the LED screen 7. The wire-retracting motor 5 retracts and releases the steel wire 11 at both ends of the LED screen 7 to ensure that the LED screen 7 is stably folded and unfolded. The folding motor 4 and the cover opening motor 3 are both push rod motors, the number of push plate motors 2 is two, the number of folding motors 4 is two, and the number of fixing slots 18 is two.

[0029] When in use, the push plate motor 2, the cover opening motor 3, the folding motor 4 and the wire taking-up motor 5 are started, and the LED screen 7 is unfolded in the process of being pushed out of the storage box 1. After unfolding, the thick steel wire rope 21 and the screw rod 23 behind the LED screen 7 are adjusted by adjusting the motor 20, so that the screens of the LED screen 7 are connected together.

[0030] Therefore, the present invention adopts a portable LED display screen with the above structure, which has a simple structure and is easy to carry and use outdoors.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
