[0002] LED displays, with their advantages of high brightness, vibrant colors, and long lifespan, are widely used in many fields such as commercial advertising, stage performances, and traffic guidance. To achieve better display effects, many LED displays are suspended, hanging them from building rooftops, above stages, or other high positions to obtain a wider visual coverage and a better viewing angle.

[0003] However, existing suspended LED displays have significant limitations in terms of maintenance. Due to their high installation position, when malfunctions occur or maintenance work such as cleaning and repair is required, staff must use ladders to work at height. Using ladders for high-altitude maintenance is not only inconvenient but also poses numerous safety hazards, such as ladder slippage and falls, which seriously threaten the lives of staff. At the same time, frequent high-altitude operations also increase the company's safety management costs and potential accident compensation risks. Therefore, we propose an LED display that is easy to suspend. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an LED display screen that is easy to hang. This design overcomes the significant limitations of existing suspended LED displays in terms of maintenance. Because the display screen is installed at a high position, when a malfunction occurs or maintenance work such as cleaning or repair is required, workers must use ladders to climb to the height. Using ladders for high-altitude maintenance is not only inconvenient but also poses many safety hazards, such as ladder slippage and falls, which seriously threaten the lives of workers. At the same time, frequent high-altitude operations also increase the company's safety management costs and potential accident compensation risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an LED display screen that is easy to hang, comprising a housing and a box body. Pins are inserted into the four corners of the front of the housing. The front of each pin is fixedly connected to the display screen body. A connecting seat is fixedly connected to the rear side of the display screen body. The rear side of the connecting seat extends through the inner cavity of the housing. A toothed plate is provided at the central axis of the inner cavity of the housing. A pull handle is fixedly connected to the bottom of the toothed plate. Gears mesh on both sides of the toothed plate. A rotating shaft is fixedly connected to the inner cavity of the gears. A limiting rod is fixedly connected to the front of the rotating shaft. One side of the limiting rod engages with the connecting seat.

[0006] Preferably, a motor is fixedly connected to the front of the housing, a take-up roller is fixedly connected to the output end of the motor, a cloth belt is fixedly connected to the surface of the take-up roller, and the bottom of the cloth belt is fixedly connected to the housing.

[0007] Preferably, a rectangular groove is provided at the central axis of the bottom of the inner cavity of the housing, and the inner cavity of the rectangular groove is slidably connected to the toothed plate.

[0008] Preferably, the rear side of the rotating shaft is movably connected to the housing via a bearing, and the front side of the housing has a slot.

[0009] Preferably, telescopic rods are fixedly connected to both sides of the bottom of the box, and the bottom of the telescopic rods is fixedly connected to the shell.

[0010] Preferably, a mounting bracket is fixedly connected to the top of the housing, and a mounting hole is provided on the rear side of the mounting bracket.

[0011] Preferably, a fixing frame is fixedly connected to the rear side of the toothed plate, and springs are fixedly connected to both sides of the top of the fixing frame, with the top of the springs fixedly connected to the housing.

[0012] Compared with the prior art, this utility model provides an LED display screen that is easy to hang, and has the following beneficial effects:

[0013] 1. When the display screen needs to be resuspended after maintenance, pull the handle downwards. The handle moves the toothed plate, which in turn rotates the gear. The gear rotates the shaft, which in turn rotates the limit rod. Then, insert the pin and connecting seat into the housing. After the display screen body contacts the housing at the rear, release the handle. At this time, the spring pull will cause the fixing frame to rise. The fixing frame moves the toothed plate, causing the limit rod to rotate again. This allows the limit rod to engage with the connecting seat, thus completing the limiting work of the display screen body.

[0014] 2. This utility model starts the motor through an external controller, which drives the winding roller to rotate and wind up the fabric belt, thereby lifting the housing. The housing then lifts the display screen body. When the housing can no longer rise, the suspension work can be completed. Attached Figure Description
