Description

Technical Field

[0001] The present invention belongs to the technical field of display screens, and in particular relates to a display screen adjustable angle hanging beam device. Background Art

[0002] A display screen, also known as an electronic display screen or a mobile display screen, is mainly responsible for emitting light and displaying various changing texts, numbers, graphic images, etc.; it can be used not only in indoor environments but also in outdoor environments, and has advantages that cannot be compared with projectors, video walls, and liquid crystal display screens. The installation of the display screen is divided into high-altitude hoisting and ground installation.

[0003] During daily use, high-altitude hoisting refers to an installation method in which the display screen is installed in a relatively high space environment through a hanging beam and ropes. This installation method has the advantages of a long visual distance and the release of ground space. When hoisting the display screen, a display screen adjustable angle hanging beam device can be used. However, the common hanging beam devices on the market at present are not convenient for conveniently adjusting the display angle of the display screen according to the actual hoisting and installation height, resulting in a limited display range of the display screen image. Moreover, it is not convenient to stably hoist and install display screens of different sizes, and the applicable range of the device is strongly limited. Therefore, there is an urgent need to improve the existing hanging beam device and provide a display screen adjustable angle hanging beam device. Summary of the Invention

By arranging the first N - pole magnet 53, due to the opposite - pole attraction between the first N - pole magnet 53 and the S - pole magnet 57, the position of the limiting plate 54 outside the fixed plate 51 can be positioned. By adjusting the distance between the two limiting plates 54, the installation of display screens of different sizes can be satisfied.

[0042] The working principle of the present invention is as follows:

[0043] When in use, first, the display screen is fixedly installed on this device, and then this device is installed on the roof through the hanging ring 2. The driving motor 32 is started to control the connecting block 33 to rotate. The connecting block 33 can drive the movable column 34 and the connecting sleeve 35 to rotate simultaneously. Since the movable column 34 is slidably connected with the connecting block 33, at this time, the connecting sleeve 35 will pull the mounting rod 36 and the mounting block 37 inside it to swing left and right. At the same time, the connecting sleeve 35 can slide up and down on the outside of the mounting rod 36. The positioning column 38 and the swing plate 39 can be driven to rotate synchronously through the mounting block 37. The display screen can be driven to rotate synchronously through the swing plate 39 that swings left and right, so that the display direction of the display screen can be adjusted, which is convenient for the full display of the display screen;

[0044] The servo motor 44 is started to control the worm 45 to rotate. During the rotation of the worm 45, the spiral shape in the middle of the worm 45 will contact and cooperate with the toothed shape in the middle of the front end of the swing plate 39, so that the assembly plate 41 and the rotating plate 42 can rotate, thereby the display screen can be rotated and adjusted in the vertical direction, and the display angle can be adjusted, which is convenient for omnidirectional display;

[0045] When actually installing the display, according to the actual size of the display, press the movable plate 55, so that the movable plate 55 squeezes the second spring 56 and slides inside the limiting plate 54. At this time, the movable plate 55 can drive the S-pole magnet 57 and the second N-pole magnet 58 to move simultaneously, making the S-pole magnet 57 move away from the first N-pole magnet 53, and the second N-pole magnet 58 moves directly above the first N-pole magnet 53. At this time, under the principle of like poles repelling each other and the action of the first spring 52, the first N-pole magnet 53 will break away from the through groove of the limiting plate 54 and enter the positioning hole of the fixing plate 51, which can release the positioning of the limiting plate 54, and then the limiting plate 54 can be controlled to move to a suitable horizontal position on the surface of the fixing plate 51. Then release the movable plate 55, and the movable plate 55 will automatically reset under the action of the second spring 56. At this time, the first N-pole magnet 53 in the other positioning hole will rise under the attraction of the S-pole magnet 57 and overcome the pulling force of the first spring 52 and enter the through groove of the limiting plate 54, which can position the limiting plate 54 so that it will not move randomly and remain stable. By adjusting the distance between the two limiting plates 54, it is convenient for the hanging beam device to be suitable for hoisting and installing display screens of different sizes.

[0046] The above are only the preferred specific embodiments of the present invention, and are not intended to limit the protection scope of the present invention; all equivalent changes, modifications, substitutions and variations made by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning or limited experiments shall be within the protection scope determined by the claims.
