The two worm gears 23 are respectively meshed with the corresponding worm gears 22, and the angle between the two strip plates 2 can be adjusted when the worm gears 23 rotate, so that the spacing between the mounting seat 1 and the fixed LED display screen can be adjusted, thereby avoiding the movement interference between the mounting seat 1 and the components installed on the rear side of the LED display screen. The front sides of the two strip plates 2 are fixedly installed with fixing plates 31, and the two L-shaped plates 3 are slidably installed on the corresponding fixing plates 31 respectively. A stopper 33 is fixedly installed on the side of the L-shaped plate 3 close to the mounting seat 1, and an adjusting screw rod 32 is rotatably installed on the side of the stopper 33 away from the mounting seat 1. The adjusting screw rod 32 is threadedly installed on the fixing plate 31, and the position of the L-shaped plate 3 can be adjusted as needed, so that the device can be better suitable for LED display screens of different sizes. The two tightening blocks 301 are respectively fixedly installed on the corresponding L-shaped plates 3 and are symmetrically arranged.
[0030] In this embodiment, in order to facilitate the operator to control the rotation of the adjusting screw 32 and the worm 23, the end of the adjusting screw 32 away from the mounting seat 1 is fixedly sleeved with an adjusting wheel 24, and the ends of the two worms 23 close to each other are fixedly installed with the same handwheel 34.
[0031] In this embodiment, in order to prevent the strip plates 2 from directly contacting the fixed LED display screen and causing damage to the LED display screen when the device is in use, rubber blocks 4 are fixedly mounted on the rear sides of the two strip plates 2 .
[0032] In this embodiment, the two pressing blocks 301 are provided with arc-shaped slots on one side close to each other, so that the two pressing blocks 301 can fix the LED display screen tightly without affecting the angle between the two strip plates 2.
[0033] The number of mounting bases 1 can be increased according to actual use needs, thereby effectively ensuring the fixing effect of the device on the LED display screen, thereby achieving better wind resistance.
[0034] The strip plate 2 is provided with a plurality of expansion holes, which facilitates the addition of components for reinforcing the LED display screen according to actual use needs, and can greatly improve the overall practicality of the device.
[0035] Working principle: When in use, first fix the base 12 in the desired position, and then adjust the positions of the two L-shaped plates 3 according to the size of the LED display screen. When adjusting, the adjusting screw rod 32 is rotated by the adjusting wheel 24. Under the action of the thread, the L-shaped plate 3 can be pushed to slide on the fixed plate 31, so that the distance between the two L-shaped plates 3 can be adjusted according to the size of the LED display screen. At the same time, the two abutting blocks 301 also move synchronously, so that the device can be better adapted to LED display screens of different sizes. Then, the LED display screen is placed on the rear side of the mounting base 1, and the bottom of the LED display screen is in contact with the rubber blocks 4 on the two strip plates 2. Then, the adjusting wheel 24 is rotated in the opposite direction to control the two abutting blocks 301 to effectively fix the LED display screen through the card slots set in the shape of an arc surface.
[0036] When other components are installed on the back of the LED display screen to be fixed and will interfere with the movement of the strip plate 2, the two worms 23 are driven to rotate synchronously by turning the hand wheel 34, and the two worms 23 then drive the corresponding worm wheels 22 to rotate. Under the action of the worm wheels 22, the two support shafts 21 can be driven to rotate synchronously, so that the angle between the two strip plates 2 can be adjusted to a position where neither of the two strip plates 2 will contact the components fixed on the back of the LED display screen, and then the L-shaped plate 3 is adjusted, and the LED display screen to be fixed is effectively fixed by two tightening blocks 301, so that the distance between the mounting base 1 and the strip plate 2 and the fixed LED display screen can be adjusted. Then, by rotating the limiting bolt 101, the limiting bolt 101 is threadedly installed in the corresponding limiting screw hole 111, so that the mounting base 1 can be fixed at the desired position on the support column 11. At this time, the device is installed. Through the setting of the rubber block 4, it is possible to avoid direct hard contact between the strip plate 2 and the fixed LED display screen when the device is in use, thereby avoiding damage to the LED display screen. The arc-shaped card groove can ensure that the angle between the two strip plates 2 changes without affecting the two clamping blocks 301 to fix the LED display screen, thereby further improving the practicability of the wind-resistant bracket on the back of the LED display screen, greatly improving the practicability of the wind-resistant bracket on the back of the LED display screen.
