Description
Technical Field
[0001] This utility model relates to the technical field of display screen support devices, and in particular to a floor support device for LED displays. Background Technology
[0002] An LED display screen is a flat panel display device that uses semiconductor light-emitting diodes (LEDs) as display elements. Countless red, green, and blue LED beads are densely arranged, and by precisely controlling the brightness of each bead, the screen can be quickly switched using the persistence of vision effect of the human eye, thus creating smooth and delicate images. With continuous technological advancements, the pixel density of LED displays is constantly increasing, moving towards ultra-high definition, bringing viewers a clearer and more detailed visual experience. It features intelligent brightness adjustment, intelligent temperature control, automatic fault detection and alarm functions, and is deeply integrated with IoT and AI technologies to achieve remote control, intelligent interaction, or data analysis applications, improving user experience and management efficiency. When support is needed for an LED display screen, a floor support device is required.
[0003] Currently available LED display floor support devices mainly consist of a base, columns, beams, connectors, and adjustment components. During use, the LED display frame is connected to the beam using specialized connectors. The hangers must be securely attached to the beam, and the corner brackets must be tightened to ensure a tight fit between the display and the beam, preventing loosening or wobbling. However, when used outdoors in windy conditions, the display may sway or even tip over. To address these issues, existing technologies only increase the size and weight of the base, using thicker, more robust metal materials and designing internal reinforcing ribs to enhance friction with the ground and overall stability. However, they do not improve the angle adjustment of the LED display floor support device. When different angles are required, the support device must be replaced, resulting in resource waste and failing to meet usage needs. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an LED display screen floor support device, which aims to improve the existing technology that does not improve the angle adjustment of the LED display screen floor support device. When different angles are required, the support device needs to be replaced, resulting in resource waste.

[0039] Working principle: When it is necessary to adjust the placement angle of the LED display screen, turn the handle 5. The rotation of the handle 5 drives the rotating bar 4 to rotate, which in turn drives the threaded rod 3 to rotate. The rotation of the threaded rod 3 drives the push block 6 to slide left and right inside the sliding groove 14. The sliding of the push block 6 drives the push rod 8 to rotate. The rotation of the push rod 8 drives the mounting plate 10 to rotate under the restriction of the rotating block 11 and the limiting block 12, thereby realizing the adjustment of the placement angle of the LED display screen and improving the utilization rate and working efficiency of the device.
[0040] When in use, if the height of the LED needs to be adjusted, the lifting rod 202 is pulled upward from the inside of the main lifting rod 203. After being pulled to the predetermined height, the limiting post 205 is inserted into the limiting hole 204 and locked in place, thereby adjusting the height of the LED display screen to accommodate different viewing heights.
