Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a fall protection device for LED displays. Background Technology

[0002] With the continuous development of technology, LED displays have been widely used in various fields, including outdoor advertising, stadiums, stage performances, and shopping malls. Due to their ability to clearly display images and videos and their many advantages such as high brightness and high contrast, they have become an important medium for information dissemination. However, LED displays are usually installed in high positions, especially large outdoor LED displays, which may be installed at heights of several meters or even more than ten meters. Such installation heights mean that if the display falls, it will cause serious safety accidents and pose a huge threat to the safety of people's lives and property.

[0003] LED displays can be installed in a variety of environments, including outdoor, indoor, high-altitude, and low-altitude conditions. When installed outdoors, they face various harsh natural environments such as strong winds, heavy rain, earthquakes, and blizzards. Strong winds may exert enormous lateral forces on the display, and earthquakes may damage the stability of the installation structure. Even indoors, unexpected situations may arise. Installing fall protection devices can provide additional safety for the display in these complex installation environments and when unexpected situations occur, reducing the risk of the display falling. Without fall protection devices, LED displays installed at heights will fall if the fixing structure becomes loose, ages, or is damaged by external forces. In densely populated areas, a falling display could directly hit people, causing serious injuries or fatalities. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a fall protection device for LED displays, aiming to improve the problem in the prior art where, if no fall protection device is installed, the display will fall and cause personal injury or death if the fixing structure becomes loose, ages, or is damaged by external forces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fall protection device for an LED display screen, comprising a frame, wherein grooves are provided on both the left and right sides of the bottom of the outer wall of the frame, a spring column is fixedly connected to the inner wall of the groove, a hollow block is provided at the bottom of the frame, a U-shaped block is slidably connected to both the left and right sides of the inner wall of the hollow block, a locking block is fixedly connected to the top of the U-shaped block, a spring column is fixedly connected to the inner wall of the hollow block, a plurality of elastic blocks are fixedly connected to the top of the inner wall of the U-shaped block, and spring sheets are fixedly connected between adjacent elastic blocks, and a fixing mechanism is provided at the top of the frame, the fixing mechanism being used to fully fix the device.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the hollow block is moved to the bottom of the device, and the U-shaped block is pulled to deform the second spring column and generate elastic force. The locking block is inserted into the groove, and the second spring column pulls the U-shaped block inward. The locking block is restricted by the groove and pushed downward by the first spring column, fitting into the groove. When the device falls, the rubber block first contacts and partially offsets the impact force, and then hits the U-shaped block, pushing the hollow block upward to squeeze the spring sheet and the first spring column, thus achieving buffering.

[0039] Working principle: Move the hollow block 7 to the bottom of the device, and then pull the U-shaped blocks 5 to both sides. The U-shaped blocks 5 will pull the spring column 8, causing the spring column 8 to deform and generate elastic force. Then, insert the locking block 6 into the groove 3, release the pulling force on both sides, and the spring column 8 will pull the U-shaped blocks 5 on both sides inward. Due to the obstruction of the groove 3, the spring column 8 will firmly restrict the locking block 6 inside the groove 3, and the spring column 4 will push the locking block 6 downward, so that the locking block 6 and the groove 3 are tightly fitted. When the device falls, the downward impact will first contact the rubber block 16. After being partially offset, it will hit the U-shaped block 5, causing the U-shaped block 5 and the hollow block 7 to move upward. This will squeeze the spring plate 9 and the spring column 4, and buffer again, thus protecting the device and preventing damage to the internal display screen 17 due to a sudden fall, which would render it unusable and cause loss.

[0040] The display screen 17 is placed inside the frame 201, and the frame 201 and frame 1 are pushed to move towards each other, so that the display screen 17 is fixed in the slot 202, and the fixing block 1 203 will contact the fixing block 204. Then, the screw 1 205 is turned in from the top of the fixing block 1 203, so that the screw 1 205 passes through the fixing block 1 203 and the fixing block 204. Finally, the nut 206 is turned in from the bottom of the screw 1 205, so that the fixing block 1 203 and the fixing block 204 are fixed together. This achieves the installation and protection of the display screen 17, and prevents the outer wall of the display screen 17 from being extensively grooved when installing the anti-fall device.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
