Figures 1-4

[0022] ​In this embodiment, the LED large screen body 1 is the core part of the display, and is responsible for displaying various images and information. The support frame 2 supports and fixes the large screen, ensures the stability and safety of the large screen, and the rotating shaft 3 is the key component for adjusting the angle of the LED large screen body 1. They allow the LED large screen to rotate around the support shell 4, so as to change the inclination angle of the large screen. The base 5 not only provides additional stability, but also ensures the firmness of the entire system, prevents accidental movement during angle adjustment, and the limiting assembly is used to stabilize the angle of the LED large screen body 1 after adjustment.

[0023] In a further preferred embodiment of the utility model, the limiting assembly includes a limiting gear 6, an adjusting block 7, a spring 8 and a clamping block 9. The limiting gear 6 is fixed on any one of the rotating shafts 3. The adjusting block 7 is rotatably installed on any one of the support shells 4. The spring 8 is fixed at the bottom of the adjusting block 7. The clamping block 9 is installed at the bottom of the spring 8. The clamping block 9 can be clamped between any two teeth of the limiting gear 6. Arc-shaped corners are arranged on the two clamping blocks 9.

[0024] In this embodiment, the limiting gear 6 rotates with the rotating shaft 3, and its teeth are designed to interact with the clamping block 9 to limit the rotation position of the rotating shaft 3 (and the LED large screen body 1). The user can adjust the relative position between the clamping block 9 and the limiting gear 6 by operating the adjusting block 7 to realize the reverse limiting and stabilization of the LED large screen body 1 at different angles. The spring 8 provides an upward spring force for the clamping block 9. When the clamping block 9 is clamped between the teeth of the limiting gear 6, the spring force of the spring 8 helps to maintain the stable position of the clamping block 9, preventing position deviation caused by vibration or external force. The arc-shaped corner design on the clamping block 9 makes it easier for the clamping block 9 to slide into or out of the gap between the teeth of the limiting gear 6. During operation, the direction of the arc-shaped corner should be opposite to the inclination direction of the LED large screen body 1 to ensure that the angle of the LED large screen body 1 can be stably fixed after clamping.

[0025] In a further preferred embodiment of the utility model, the top of each of the two clamping blocks 9 is provided with a limiting rod 18, and the two adjusting blocks 7 are provided with limiting openings. The two limiting rods 18 can extend to the top of the two support shells 4 through the two limiting openings respectively.

[0026] In this embodiment, the limiting rod 18 is designed to be vertically extendable to increase the control of the position of the clamping block 9. The limiting port corresponds to the limiting rod 18, allowing the limiting rod 18 to pass through while providing certain guidance and limitation to its movement. When the clamping block 9 is clamped between the teeth of the limiting gear 6 under the elastic force of the spring 8, the limiting rod 18 will also pass through the limiting port on the adjusting block 7 and extend to the top of the support shell 4. This design not only strengthens the connection between the clamping block 9 and the adjusting block 7, but also provides additional stability to prevent the clamping block 9 from accidentally disengaging from the limiting gear 6 when subjected to external forces. The design of the limiting rod 18 passing through the limiting port further ensures the stable position of the clamping block 9 on the limiting gear 6. This double limiting mechanism greatly reduces the angle deviation caused by vibration, wind force or other external forces, and limits the bending extension direction of the spring 8.

[0027] In further preferred embodiments of the present application, the top of each of the two limiting rods 18 is provided with a pull ring 11, and the top of each of the two adjusting blocks 7 is fixed with a handle 12.

[0028] In this embodiment, the design of the pull ring 11 allows the user to move the limiting rod 18 by simply pulling it, thereby controlling the position of the clamping block 9 and facilitating the adjustment of the direction of the adjusting block 7. The introduction of the handle 12 makes it easier for the user to hold and rotate the adjusting block 7. The mounting bracket 16 serves as a fixed platform for installing and supporting other accessories. The controller 17 is used to control or automate the switching of the LED large screen body 1. When adjusting the angle of the LED large screen body 1, the user can first easily pull up the limiting rod 18 by the pull ring 11, causing the clamping block 9 to disengage from the teeth of the limiting gear 6, thereby changing the angle of the LED large screen body 1. When the desired angle is reached, the pull ring 11 is released, and the clamping block 9 is reinserted between the teeth of the limiting gear 6 under the elastic force of the spring 8, thereby fixing the angle of the LED large screen body 1.

[0029] In further preferred embodiments of the present application, the two rotating shafts 3 are each fixed with a limiting plate 13, and the two limiting plates 13 are each provided with two support rods 14. The two support shells 4 are each hingedly connected with a clamping plate 15, and the two clamping plates 15 can be respectively clamped outside the two limiting plates 13. The two clamping plates 15 can be respectively fixedly connected with any two support rods 14.

[0030] In this embodiment, the limiting plate 13 serves as a support and limiting structure to enhance the connection strength between the rotating shaft 3 and the support shell 4. In combination with the clamping plate 15, it can ensure the vertical angle between the LED large screen body 1 and the base 5. The support rod 14 provides support and fixing points for the clamping plate 15.

[0031] The further preferable embodiment of the utility model further provides two adjusting blocks 7 are all embedded with a plurality of ball bearings 10, two support shells 4 are all equipped with limiting grooves, a plurality of ball bearings 10 are in contact with the inner wall of two limiting grooves respectively.

[0032] In the embodiment, the ball bearing 10 is used as a rolling element, which can form rolling contact between the adjusting block 7 and the support shell 4, thereby greatly reducing the friction coefficient and improving the smoothness of sliding.

[0033] The further preferable embodiment of the utility model further provides that the support frame 2 is equipped with a plurality of heat dissipation openings, the bottom of the mounting frame 16 is installed with a plurality of stabilizing rods, the plurality of stabilizing rods are all fixedly connected with the support frame 2, two clamping plates 15 are both made of iron, two support shells 4 are both installed with magnet blocks, and two clamping plates 15 can be respectively adsorbed on two magnet blocks.

[0034] In the embodiment, the design of the heat dissipation opening aims to improve the heat dissipation performance of the support frame, help the LED large screen body 1 effectively dissipate the generated heat in the long-time use process, prevent performance degradation or damage caused by overheating, enhance the overall stability of the mounting frame 16, prevent shaking or toppling caused by external force, and improve the safety of the system.

[0035] In summary, compared with the related art, the device is convenient for rotating and adjusting the angle of the LED large screen body 1 by setting the rotating shaft 3 to cooperate with the support shell 4 to support the support frame 2, can stabilize the LED large screen body 1 tilted in different directions by setting the limiting assembly, and can limit the LED large screen body 1 in the vertical state by setting the limiting plate 13 to cooperate with the clamping plate 15, thereby preventing the LED large screen body 1 from directly toppling under the influence of the arc-shaped corner.
