[0024] Please refer to Figures 1-3 A kind of adjustable visual angle's LED display screen mounting bracket, including hinged axle 1, hinged axle 1 is hinged with base plate 2, the back surface of base plate 2 is fixedly connected with movable first movable shaft 3, the back surface of hinged axle 1 is fixedly connected with L type frame 4, see Figure 2As shown, the L-shaped frame 4 and the hinge shaft 1 are fixedly connected by a set of two reinforcing ribs. The reinforcing ribs distribute the weight, preventing localized overload and improving the overall load-bearing capacity. An electric telescopic rod 5 is fixedly connected to the inner side of the L-shaped frame 4. The input end of the electric telescopic rod 5 is electrically connected to a connecting wire, and one end of the connecting wire is electrically connected to a PLC controller. The PLC controller allows for real-time start and stop of the electric telescopic rod 5, facilitating user operation. A second movable shaft 6 is fixedly connected to one end of the electric telescopic rod 5. The second movable shaft 6 and... The first movable axis 3 is movably connected to the second movable axis 6 via the movable rod 7. The second movable axis 6 is moved by the electric telescopic rod 5. During the movement of the second movable axis 6, a pushing or pulling force is generated, which changes the angle of the movable rod 7. When the angle of the movable rod 7 changes, it can drive the first movable axis 3 to move. The first movable axis 3 drives the base plate 2 to move. Since the bottom of the base plate 2 is hinged to the inside of the hinge shaft 1, the angle of the base plate 2 changes with the movement of the first movable axis 3, while its own position does not change. This achieves the purpose of adjusting the viewing angle and greatly improves the viewing experience.

[0025] See Figure 2 As shown, a power supply box is fixedly connected to the bottom of the inner side of the L-shaped frame 4, and the inner cavity of the power supply box is equipped with a storage battery. The storage battery provides power to the electrical equipment, maintaining its normal operation. Figure 3 As shown, a groove 8 is provided on the top of the substrate 2, and a slider 9 is slidably connected to the inner wall of the groove 8. A threaded groove is provided on the slider 9, and the thread in the threaded groove is compatible with the thread on the surface of the fastening bolt 12. By utilizing the compatibility between the threads, the fastening bolt 12 can be quickly screwed into the threaded groove through the through hole 11, which greatly improves the efficiency of disassembly and assembly. One end of the slider 9 is fixedly connected to a mounting plate 10. A set of through holes 11 is provided on the top of the back of the substrate 2. The slider 9 and the through holes 11 are fixedly connected by the fastening bolt 12. The fastening bolt 12 is unscrewed from the connection between the through hole 11 and the slider 9 to release the limitation on the slider 9. After the limitation is released, the two mounting plates 10 are held and moved in different directions. By changing the distance between the two mounting plates 10, the mounting plates 10 can be used to install displays of different sizes. Similarly, after the adjustment is completed, the slider 9 can be fixed again by the fastening bolt 12, which improves the applicability of the device.

[0026] In use, first unscrew the fastening bolt 12 from the connection between the through hole 11 and the slider 9 to release the limiting position on the slider 9. After the limiting position is released, hold the two mounting plates 10 and move them in different directions. By changing the distance between the two mounting plates 10, the mounting plates 10 can be used to install displays of different sizes. Similarly, after adjustment, the slider 9 can be fixed again by tightening the fastening bolt 12, which improves the applicability of the device. When the viewing angle needs to be adjusted, start the electric telescopic rod 5. Because the electric telescopic rod 5 has an internal drive mechanism, it generates power through power supply. This drives the electric telescopic rod 5 to extend and retract, which in turn moves the second movable shaft 6. During this movement, the second movable shaft 6 generates a pushing or pulling force, which in turn changes the angle of the movable rod 7. When the angle of the movable rod 7 changes, it can move the first movable shaft 3, which in turn moves the base plate 2. Since the bottom of the base plate 2 is hinged to the inside of the hinge shaft 1, the angle of the base plate 2 changes with the movement of the first movable shaft 3, while its own position remains unchanged. This achieves the purpose of adjusting the viewing angle and greatly improves the viewing experience.
