The stabilizing device 3 protects the overall equipment from overturning.

[0032] The above-mentioned structures together constitute the general appearance structure of the LED display screen protection device of the utility model.

[0033] In order to further explain the specific working principle of a LED display screen protection device of the utility model, the fixing device 16 includes a positioning shaft 1601 located in the through groove 15, and a connected groove three 1603 is opened on the top wall and the bottom wall of the through groove 15, and a baffle 1602 is slidably connected in the groove three 1603 at the top and bottom ends. It is worth noting that the baffles 1602 at the top and bottom ends are fixedly connected to the positioning shaft 1601, and then the front ends of the baffles 1602 at the bottom and top ends are fixedly connected with springs 1604, and finally the front end of the spring 1604 is fixedly connected to the inner wall of the groove three 1603.

[0034] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when stationary, the positioning shaft 1601 passes through the through slot 15 and extends into the positioning hole 14. At this time, the positioning shaft 1601 ensures that the relative position between the positioning hole 14 and the through slot 15 is restricted; then, when the position needs to be adjusted, the positioning shaft 1601 is pulled outward. At this time, the positioning shaft 1601 drives the baffle 1602 to move outward, and the baffle 1602 compresses the spring 1604 outward. When the positioning shaft 1601 is completely moved out of the positioning hole 14, the user can adjust the height. When the through slot 15 is aligned with another positioning hole 14, the user releases the positioning shaft 1601, and the spring 1604 will push the baffle 1602 to return to its original position, that is, the positioning shaft 1601 enters the positioning hole 14, completing an example of adjusting the height.

[0036] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the display is placed on the device, the weight of the display screen will be transferred to the positioning column 303 along the base 1, and then the positioning column 303 will push the disc 304 down, and at the same time the disc 304 will press down the spring 2 305 and the damper 306. In this process, the cavity above the disc 304 becomes larger due to the space expansion, and at the same time, the disc 304 and the inner wall of the shell 2 302 are sealed, so that the air pressure in the cavity above the disc 304 gradually decreases. Due to the pressure difference, the gas in the suction cup 307 will be sucked into the cavity above the disc 304 along the air ducts 308 on both sides. At this time, the air pressure in the suction cup 307 is less than the external atmospheric pressure, resulting in a certain pressure difference. This pressure difference will firmly stabilize the device on the desktop.
