[0031] A support assembly 6, the support assembly 6 is arranged at the bottom of the rectangular plate 1;

[0032] The flip limit component 4 is arranged at the upper end of the vertical rod 3 and the LED screen 2. The flip limit component 4 includes a rectangular block 4-1, which is fixed at the upper end of the vertical rod 3. A limiting column 4-2 is arranged on the upper end surface of the rectangular block 4-1. A flip rod 4-3 is rotatably connected between the rectangular blocks 4-1. The LED screen 2 is fixed on the bottom surface of the flip rod 4-3. A pair of grooves 4-4 are opened on the top of the flip rod 4-3. An inner rod 4-5 is fixedly connected in the groove 4-4. The outer sliding sleeve of the inner rod 4-5 is connected to a moving frame 4-6. A limiting groove 4-7 is opened on the side end surface of the moving frame 4-6. The outer sleeve of the inner rod 4-5 is connected to a spring 4-8.

[0033] In this embodiment, in order to achieve a flip display effect of the LED screen 2, a flip limit assembly 4 is designed. A rectangular block 4-1 is fixedly connected to the top of the vertical rod 3, and a flip rod 4-3 is rotatably connected between the rectangular blocks 4-1. The LED screen 2 is fixed to the bottom of the flip rod 4-3, and the LED screen 2 can be flipped upward by the flip rod 4-3. A limit column 4-2 is set on the top of the rectangular block 4-1, and two grooves 4-4 are opened on the top of the flip rod 4-3, and an inner rod is set inside. 4-5, a moving frame 4-6 and a spring 4-8 are slidably mounted on the inner rod 4-5, and a limiting groove 4-7 is provided on the side end surface of the moving frame 4-6. The limiting groove 4-7 can be pushed and mounted on the inner rod 4-5 by the elastic force of the spring 4-8, so that the flip rod 4-3 cannot be flipped, and the moving frame 4-6 can be pushed to move in the groove 4-4, and then released when it is flipped after being separated from the inner rod 4-5. The limiting groove 4-7 at the front end of the moving frame 4-6 can be fixed with the vertical rod 3, which also achieves the limiting effect.

[0034] Furthermore, the telescopic component 5 includes an inner groove 5-1, which is opened on the top of the rectangular plate 1. A pair of long grooves 5-2 are opened on both sides of the inner groove 5-1. The lower end of the vertical rod 3 is inserted and connected in the long groove 5-2. A long hole 5-3 is opened on the surface of the vertical rod 3. Side holes 5-4 are opened on the opposite end surfaces of the outer side of the rectangular plate 1. The side holes 5-4 are connected with the inside of the long groove 5-2. Inner columns 5-5 are fixedly connected to the two side surfaces of the inner groove 5-1. The inner columns 5-5 are movably mounted in the long holes 5-3. The side end surfaces of the vertical rod 3 are screwed with locking bolts 5-6 through threaded cooperation. The locking bolts 5-6 are movably mounted in the side holes 5-4.

[0035] In the present embodiment, in order to achieve the effect that the LED screen 2 can be retracted into the interior of the rectangular plate 1, a telescopic component 5 is designed, an inner groove 5-1 is opened in the rectangular plate 1, and long grooves 5-2 are opened on both sides of the inner groove 5-1, the vertical rod 3 is movably mounted in the long groove 5-2, and a long hole 5-3 is opened on the surface of the vertical rod 3. There are two inner columns 5-5 in the inner groove 5-1, and the inner column 5-5 is movably mounted in the long hole 5-3 of the vertical rod 3, which has the effect of strengthening the connection and support of the vertical rod 3, and a side hole 5-4 is opened on the inner side of the inner groove 5-1, and a locking bolt 5-6 is screwed through the side hole 5-4 and connected to the inside of the vertical rod 3 by threading. When the vertical rod 3 is extended upward, it can be fixed by the locking bolt 5-6, so that the LED screen 2 can be fixed at any height.

[0036] Furthermore, the support assembly 6 includes a base 6-1, which is fixed at the bottom of the rectangular plate 1. Side openings 6-2 are opened on both sides of the rectangular plate 1. Support legs 6-3 are rotatably connected to the side openings 6-2 through pins, and the bottom surfaces of the support legs 6-3 and the bottom surfaces of the base 6-1 are located in the same plane.

[0037] In this embodiment, in order to achieve a stable support effect on the ground, a support component 6 is designed, and a base 6-1 is provided at the bottom of the rectangular plate 1. Two side openings 6-2 are provided on both sides of the base 6-1. Support legs 6-3 are rotatably connected to the side openings 6-2 through pin shafts. The support legs can be rotated outward in the side openings 6-2 and unfolded, so that the overall structure is stably supported on the ground.

[0038] Furthermore, the diameter of the limiting column 4 - 2 is the same as the diameter of the vertical rod 3 .

[0039] In this embodiment, the limiting column 4 - 2 and the vertical rod 3 have the same diameter, so they can maintain a tight and firm fit with the limiting groove 4 - 7 .

[0040] Furthermore, the flip rod 4-3 can be flipped 180 degrees by rotating the connection with the rectangular block 4-1.

[0041] In this embodiment, the LED screen 2 can be flexibly flipped for display according to usage conditions through a flip angle of 180°.

[0042] Furthermore, a handle 7 is fixedly connected to the top of the flip rod 4-3.

[0043] In this embodiment, by installing a handle 7 on the top of the flip rod 4 - 3 , the entire structure can be lifted up and carried by the handle 7 .

[0044] When it is needed, the whole structure is lifted up by the handle 7, moved to the use position, the supporting legs 6-3 are opened outward, and then the locking bolts 5-6 are loosened, and the LED screen 2 is lifted outward by the handle 7, and the vertical rod 3 is extended outward in the long groove 5-2. After extending to a suitable height, the locking bolts 5-6 are tightened to fix the vertical rod 3. When the LED screen 2 needs to be flipped over for use, the movable frames 4-6 on both sides are pulled to separate the limit grooves 4-7 from the limit columns 4-2, and then the flip rod 4-3 is rotated 180° upwards, and then the movable frames 4-6 are loosened to make the limit grooves 4-7 fit and fix with the vertical rod 3, and then it can be started to be used.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
