DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments.

[0029] As Figures 1-6 shown, the electric opening and closing LED screen provided by the embodiment comprises guide rails B2, the guide rails B2 are provided with two groups, outer walls of the guide rails B2 are fixedly connected with symmetrically distributed guide rails A1, and the electric opening and closing LED screen further comprises:

[0030] an anti-impact assembly, the anti-impact assembly comprises a rubber ring 17 slidingly connected in the guide rails A1 and the guide rails B2, an inner wall of the rubber ring 17 is fixedly connected with a rotating wheel 19, an inner wall of the rotating wheel 19 is rotatably connected with uniformly distributed connecting rods 21, one end of the connecting rods 21 away from the rotating wheel 19 is rotatably connected with a connecting shell 20, an inner wall of the connecting shell 20 is rotatably connected with a connecting column 18, an outer wall of the connecting rods 21 is sleeved with strong springs 22, the strong springs 22 are fixedly connected with the connecting shell 20, one end of the strong springs 22 away from the connecting shell 20 is fixedly connected with the rotating wheel 19, in the moving process of the top mounting plate 13 and the bottom mounting plate 14, if shaking occurs, the connecting column 18 will be extruded outward, and force is transmitted to the connecting rods 21 and the strong springs 22 through the connecting shell 20, the strong springs 22 generate reverse elastic force after being compressed, the impact force is offset, at the same time, the rubber ring 17 further disperses the impact force, reduces the shaking of the top mounting plate 14 and the bottom mounting plate 13 in the moving process, and the LED screen is protected;

[0031] a rotating seat A10 fixedly connected with an outer wall of the supporting plate 3, and an outer wall of the rotating seat A10 is rotatably connected with the sliding electric push rod 11;

[0032] a lifting assembly arranged on outer walls of the guide rails A1 and the guide rails B2;

[0033] a mounting assembly arranged on an outer wall of the connecting column 18.

[0034] As Figures 2-3As shown, in a preferred embodiment, based on the above method, the lifting assembly further includes a support plate 3 symmetrically fixedly connected to the outer walls of guide rail A1 and guide rail B2. A guide seat 4 is fixedly connected to the outer wall of the support plate 3. Symmetrically distributed rhomboid frames 5 are arranged between the symmetrical guide seats 4. Uniformly distributed rotating rods 6 are rotatably connected between the symmetrical rhomboid frames 5. A fixed seat A7 is fixedly connected to the outer wall of the rotating rod 6. A fixed seat B8 is also fixedly connected to the outer wall of the rotating rod 6. A lifting electric push rod 9 is rotatably connected to the outer wall of the fixed seat A7, and the output end of the lifting electric push rod 9 is rotatably connected to the fixed seat B8. When the lifting electric push rod 9 is activated, its output end begins to extend and retract. The fixed base B8 pulls the connected rotating rod 6. Due to the diamond structure of the diamond frame 5, when the output end of the lifting electric push rod 9 extends, the overall height of the diamond frame 5 decreases. When the output end of the lifting electric push rod 9 retracts, the overall height of the diamond frame 5 increases. The shape of the diamond frame 5 changes, thereby driving the entire structure to change its height position between the guide seats 4, realizing the height adjustment of the guide rails A1 and B2. At the same time, the top mounting plate 13 and the bottom mounting plate 14 slide relative to each other to adapt to the height change between the guide rails A1 and B2, so that the distance between the guide rails A1 and B2 can adapt to different space sizes, making it convenient to install LED screens of different sizes.

[0035] like Figures 3-4 As shown, in a preferred embodiment, based on the above method, the mounting assembly further includes a bottom mounting plate 13 and a top mounting plate 14 fixedly connected to the outer wall of the connecting column 18, and the bottom mounting plate 13 and the top mounting plate 14 are slidably connected. The top wall of the bottom mounting plate 13 is fixedly connected with evenly distributed sliding rods 15, and the sliding rods 15 are slidably connected to the top mounting plate 14. The outer walls of the top mounting plate 14 and the bottom mounting plate 13 are both provided with evenly distributed mounting holes 16. The top mounting plate 14 and the bottom mounting plate 13 slide according to the distance between the guide rail A1 and the guide rail B2. The LED screen body 23 is installed through the mounting holes 16.

[0036] like Figure 2 As shown, in a preferred embodiment, based on the above method, a rotating seat B12 is fixedly connected to the outer wall of both the top mounting plate 14 and the bottom mounting plate 13, and the rotating seat B12 is rotatably connected to the output end of the sliding electric push rod 11. When the sliding electric push rod 11 pulls the top mounting plate 14 or the bottom mounting plate 13, it rotates adaptively through the rotating seat B12.

[0037] like Figure 1 As shown, in a preferred embodiment, based on the above method, the top mounting plate 14 and the bottom mounting plate 13 are further connected by a mounting hole 16, and the LED screen body 23 is installed through the mounting hole 16.

[0038] Specifically, when using this electrically operated LED screen: The lifting electric push rod 9 is activated, and its output end begins to extend and retract, pulling the connected rotating rod 6 through the fixed seat B8. Due to the rhomboid structure of the rhomboid frame 5, when the output end of the lifting electric push rod 9 extends, the overall height of the rhomboid frame 5 decreases; when the output end of the lifting electric push rod 9 retracts, the overall height of the rhomboid frame 5 increases, changing its shape. This, in turn, causes the entire structure to change its height position between the guide seats 4, achieving height adjustment of guide rails A1 and B2. Simultaneously, the top mounting plate 13 and the bottom mounting plate 14 slide relative to each other to adapt to the height changes between guide rails A1 and B2, allowing the distance between guide rails A1 and B2 to adapt to different space sizes, facilitating the installation of LED screens of different sizes. Then, the LED screen body 23 is installed through the mounting holes 16. When opening or closing is required, the top mounting plate 14 and the bottom mounting plate 13... The shock-resistant component slides within guide rails A1 and B2. Specifically, it extends and retracts via the output end of the sliding electric push rod 11. Since it is rotatably connected to the rotating seat B12 on the outer wall of the top mounting plate 14 and the bottom mounting plate 13, the extension and retraction will cause the top mounting plate 14 and the bottom mounting plate 13 to move along guide rails A1 and B2, thereby causing the LED screen body 23 to move accordingly, thus realizing the electric opening and closing of the LED screen body 23. If shaking occurs during the movement of the top mounting plate 13 and the bottom mounting plate 14, the connecting column 18 will be squeezed outwards and the force will be transmitted to the connecting rod 21 and the strong spring 22 through the connecting shell 20. The strong spring 22 generates a reverse elastic force after being compressed, which offsets the impact force. At the same time, the rubber ring 17 further disperses the impact force, reducing the shaking of the top mounting plate 14 and the bottom mounting plate 13 during movement, thus protecting the LED screen.

[0039] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
