Description

Technical Field

[0001] The utility model belongs to the technical field of display screens, and particularly relates to a lifting type LED display screen. Background Art

[0002] LED display screens are divided into graphic display screens and video display screens, both of which are composed of LED matrix blocks. Graphic display screens can display Chinese characters, English text and graphics synchronously with computers; video display screens are controlled by microcomputers, with graphics, images and rich graphics, playing various information in a real-time, synchronous and clear information transmission method, and can also display two-dimensional, three-dimensional animations, videos, TV, VCD programs and live scenes. The application range is extremely wide. For example, the height and angle of computer display screens need to be adjusted for ease of use:

[0003] The existing Chinese patent publication number CN219755868U is a lifting LED display screen: "including a cross-shaped base, two columns are fixedly installed on the surface of the cross-shaped base, and a lifting device is provided on the surface of one of the columns, and the lifting device includes a vertical groove, and the vertical groove is opened on the surface of one of the columns, and a sliding plate is slidably connected inside the vertical groove, and a rack is fixedly installed on the surface of the sliding plate, wherein a through groove is opened on the surface of the other column, and a sliding rod is fixedly installed between the inner walls at both ends of the through groove, and a slide plate is slidably connected to the surface of the slide rod, and a display screen body is fixedly installed on the side of the slide plate, and the top of the rack is fixedly connected to the display screen body";

[0004] The lifting structure is arranged outside, and although the height can be adjusted, it is easy to cause damage to the lifting structure and affect the aesthetics of the LED display.

[0005] Therefore, the existing lifting type LED display screen cannot meet the needs in actual use, so the market is in urgent need of improved technology to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a lifting type LED display screen, which hides the positions of the positioning rod, the locking teeth, the spring returner and the rack by setting a U-shaped plate, thereby solving the problem that the lifting structure is set outside, although the purpose of adjusting the height can be achieved, it is easy to cause damage to the lifting structure and affect the aesthetics of the LED display screen.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0009] Furthermore, a handle frame is fixedly provided in the middle of the top end of the positioning rod, and multiple anti-slip grooves are evenly arranged on the outer walls of the handle frame on both sides opposite to each other. Two limit grooves are evenly arranged in the middle of both ends of the positioning rod. The handle frame is convenient for the user to pull the screen and the shell to move, and the anti-slip grooves are convenient for increasing the surface friction of the handle frame.

[0010] Furthermore, two sliders are evenly fixed inside the two ends of the rack, and four sliding grooves are symmetrically opened on the inner walls of the two sides of the U-shaped plate about its vertical center line. The two sliders slide evenly inside the four sliding grooves, and the moving position of the rack is limited by the cooperation of the sliders and the sliding grooves to prevent the rack from shifting during the movement, which will cause the spring returner to be unevenly stressed and twisted.

[0011] Furthermore, two limit frames are evenly fixed on the top inner walls on both sides of the U-shaped plate, and the two limit frames slide evenly inside the two limit grooves. The position of the positioning rod is limited by the limit frames and the limit grooves to prevent the positioning rod from shifting during movement and causing jamming.

[0012] Furthermore, two round rods are evenly fixed on the bottom of the outer wall of one side of the two U-shaped plates, and screw rods are fixed on one end of the two round rods, and the positions of the screw rods are fixed by the cooperation of the U-shaped plates and the round rods.

[0013] Furthermore, it also includes a support ring with two rotating frames evenly fixed on the top of both ends, the round rod rotates inside the rotating frame, and a knob is screwed on the outer cylindrical surface of the screw rod. The support ring and the round rod are used in combination to facilitate the rotation of the screen and the shell to complete the angle adjustment, and the position of the round rod is fixed by the knob and the screw, thereby fixing the position of the screen and the shell after the angle adjustment is completed.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model hides the positions of the positioning rod, the clamping teeth, the spring returner and the rack by setting a U-shaped plate, which protects the lifting structure while not affecting the overall aesthetics of the lifting LED display.

[0016] 2. The utility model supports and fixes the position of the liftable LED display screen by arranging round rods, screw rods, support rings, rotating frames and knobs, and facilitates the angle adjustment, so that users can use the liftable LED display screen.

The two sliders 206 slide evenly inside the four slide grooves 207. The sliders 206 and the slide grooves 207 are used in conjunction with each other to limit the moving position of the rack 204 to prevent the rack 204 from deviating during the movement, resulting in uneven force on the spring returner 203 and torsion. The top inner walls of the two sides of the U-shaped plate 201 are evenly fixed with two The limiting frame 208 and the two limiting frames 208 slide evenly inside the two limiting grooves 107. The limiting frame 208 and the limiting grooves 107 are used in conjunction with each other to limit the position of the positioning rod 104 to prevent the positioning rod 104 from shifting during movement and causing jamming. Two round rods 209 are evenly fixed at the bottom of the outer wall on one side of the two U-shaped plates 201, and screws 210 are fixed at one end of the two round rods 209. The position of the screws 210 is fixed by the cooperation of the U-shaped plate 201 and the round rods 209.
