Due to its high brightness, wide viewing angle, long life and other characteristics, it is being widely used in products such as outdoor advertising screens. When using LED displays, support columns are required to support them.

[0003] At present, the supporting columns used in LED display screens are mainly composed of a base, a supporting column and a curved supporting member at the top. The LED display screen is embedded in the supporting member. The supporting columns used in existing LED displays are usually simple in function and often only have a simple lifting and adjusting function, but do not have the function of adjusting the angle of the LED display. Therefore, in actual use, the viewing angle of the LED display on the pillar is not convenient for people of different heights to watch, and the use effect needs to be improved. In view of the above problems, we propose a new type of LED display column. Utility Model Content

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides an LED display column, including a U-shaped frame 2, a rotating mechanism 3 is provided on one side outer surface of the U-shaped frame 2, a positioning mechanism 4 is provided on one side outer surface of the U-shaped frame 2 at a position outside the rotating mechanism 3, the rotating mechanism 3 includes a first gear 301, a first connecting shaft 302 is fixedly connected at the center of one side outer surface of the first gear 301, the first connecting shaft 302 is rotatably connected to the one side outer surface of the U-shaped frame 2, a second gear 303 is meshingly connected to the outer surface of the first gear 301, a second connecting shaft 304 is fixedly connected at the center of one side outer surface of the second gear 303, the second connecting shaft 304 is rotatably connected to the one side outer surface of the U-shaped frame 2, a third connecting shaft 305 is fixedly connected at the center of the other side outer surface of the second gear 303, and one end of the third connecting shaft 305 is connected to a rotating handle 306 A support column 11 is fixedly connected to the bottom center of the U-shaped frame 2, and a support seat 1 is fixedly connected to the bottom end of the support column 11. A rotating shaft 21 is rotatably connected between the inner walls of the U-shaped frame 2, and a mounting seat 22 is fixedly connected to the outer surface of the rotating shaft 21. The number of teeth of the second gear 303 is less than the number of teeth of the first gear 301. One end of the rotating shaft 21 is fixedly connected to one end of the first connecting shaft 302, and a mounting groove 23 is provided at the top of the mounting seat 22. The positioning mechanism 4 includes a mounting shell 401, and a connecting plate 404 is fixedly connected to the inner wall of one side of the mounting shell 401 near the bottom. A telescopic rod 405 is fixedly connected to the top of the connecting plate 404, and an engaging block 407 is fixedly connected to the top of the telescopic rod 405. A spring 406 is sleeved on the outside of the telescopic rod 405, and the top of the engaging block 407 is meshed with the outer surface of the second gear 303.

[0023] The effect achieved by the entire embodiment 1 is that the support base 1 and the support column 11 in the device form a column body, and the mounting groove 23 on the top of the mounting base 22 is mainly used to install the LED display. When the device is in use, the third connecting shaft 305 can drive the second gear 303 to rotate by holding and turning the handle 306, and the second gear 303 will drive the first gear 301 to rotate when it rotates, and the first gear 301 will drive the rotating shaft 21 to rotate through the first connecting shaft 302 when it rotates. At this time, the mounting base 22 on the surface of the rotating shaft 21 will follow the rotation, thereby achieving the effect of adjusting the viewing angle of the LED display inside the mounting groove 23. The use effect can be improved by adjusting the pitch angle of the LED display for different users. The number of teeth of the second gear 303 is smaller than that of the first gear 301, which has the effect of reducing speed and increasing torque, so that the second gear 303 is easier to rotate, and the pitch angle of the LED display can be slowly adjusted.

[0024] Embodiment 2, as Figure 1-Figure 4As shown, the mounting shell 401 is fixedly connected to the outer surface of one side of the U-shaped frame 2, the outer surface of the third connecting shaft 305 passes through the outer surface of the mounting shell 401, a movable groove 402 is provided on the outer surface of one side of the mounting shell 401 near the bottom, a stopper 403 is symmetrically fixedly connected to the outer surface of one side of the mounting shell 401 near the movable groove 402, a fourth connecting shaft 408 is fixedly connected to the outer surface of one side of the engaging block 407, the position of the fourth connecting shaft 408 corresponds to the movable groove 402, and one end of the fourth connecting shaft 408 is rotatably connected to a butterfly piece 409.

[0025] The effect achieved by the entire embodiment 2 is that when the second gear 303 is rotated, the butterfly piece 409 can be pinched to drive the meshing block 407 to move downward through the fourth connecting shaft 408, so that the meshing block 407 and the second gear 303 are disengaged. When the butterfly piece 409 moves below the two blocks 403, it is rotated from a vertical state to a horizontal state. At this time, the butterfly piece 409 will be stuck by the two blocks 403. When the angle adjustment of the mounting seat 22 is completed, the butterfly piece 409 is rotated to a vertical state again. At this time, the spring 406 rebounds and pushes the meshing block 407 to move upward, and the vertical butterfly piece 409 will pass through the two blocks 403. When the meshing block 407 and the second gear 303 are meshed, the second gear 303 cannot be rotated, which has the effect of fixing the mounting seat 22. The design structure is simple and improves the convenience during adjustment. The telescopic rod 405 serves to limit the meshing block 407 when it moves up and down.

[0026] Working principle: When the device is in use, the third connecting shaft 305 can drive the second gear 303 to rotate by holding and rotating the handle 306, and the second gear 303 can drive the first gear 301 to rotate when the second gear 303 rotates, and the first gear 301 can drive the rotating shaft 21 to rotate through the first connecting shaft 302 when the first gear 301 rotates. At this time, the mounting seat 22 on the surface of the rotating shaft 21 will rotate accordingly, thereby adjusting the viewing angle of the LED display inside the mounting slot 23. The use effect can be improved by adjusting the pitch angle of the LED display for different users. When rotating the second gear 303, the butterfly piece 409 can be pinched through the fourth connecting shaft 408 After driving the meshing block 407 to move downward, the meshing block 407 and the second gear 303 are disengaged. When the butterfly piece 409 moves to the bottom of the two blocks 403, it is rotated from the vertical state to the horizontal state. At this time, the butterfly piece 409 will be stuck by the two blocks 403. When the angle adjustment of the mounting seat 22 is completed, the butterfly piece 409 is rotated to the vertical state. At this time, the spring 406 rebounds and pushes the meshing block 407 to move upward, and the vertical butterfly piece 409 passes through the two blocks 403. When the meshing block 407 and the second gear 303 are meshed, the second gear 303 can be prevented from rotating, which has the effect of fixing the mounting seat 22. The design structure is simple.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
