Description

Technical Field

[0001] The utility model relates to the technical field of LED display screen movement, in particular to a movable LED display screen. Background Art

[0002] LED screens are a new type of electronic device made of sequentially arranged light-emitting diodes. Due to their high brightness, wide viewing angle, and long lifespan, they are widely used in products such as outdoor advertising screens.

[0003] The use of LEDs for lighting will first replace power-hungry incandescent lamps and then gradually expand throughout the lighting market, saving significant amounts of electricity. Recently, white LEDs have reached a point where a single LED consumes over 1 watt and outputs 25 lumens, increasing their practicality.

[0004] An LED display is a flat-panel display composed of small LED modules. It is used to display text, images, video, and recordings. The color and efficiency of LEDs depend on the materials and process used to manufacture them. Initially, the light bulbs emit a pure blue light. Phosphor is then added to adjust the light color to suit the user's needs. Four widely used colors are red, green, blue, and yellow.

[0005] Existing LED display screens are usually installed on mounting brackets, and are usually fixed on the brackets, making it difficult for some people with special visual impairments to adjust the distance of the display screen, and existing LED display screens are difficult to move, causing some troubles for such people.

[0009] The fixed column is provided with a sliding groove, and a second driving frame is provided in the sliding groove, and the other end of the second driving frame is positioned on the outside of the mounting bracket through a mounting hinge, and a lifting groove is provided on the mounting bracket, and a first driving frame is provided on one side of the lifting groove, and the other end of the first driving frame passes through the lifting groove and is connected to the first sliding key.

[0010] In addition, a preferred structure is that the other end of the first driving frame is fixed below the fixed column through a mounting hinge, and a damping shaft is transversely mounted at the middle intersection of the first driving frame and the second driving frame.

[0011] In addition, a preferred structure is that the mounting bracket is also hollow, and mounting plates are mounted at the four inner corners of the mounting bracket by fixing screws, and positioning holes are opened on the mounting plates.

[0012] In addition, a preferred structure is that when the other ends of the first sliding key and the second driving frame are respectively at the bottom of the lifting groove and the sliding groove, the first driving frame and the second driving frame are in a cross state.

[0013] In addition, a preferred structure is that when the other ends of the first sliding key and the second driving frame are respectively at the top of the lifting slot and the sliding slot, the first driving frame and the second driving frame are in a retracted state.

[0014] In addition, a preferred structure is that when the damping shaft moves through the first driving frame and the second driving frame, the damping shaft moves back and forth in a straight line in the horizontal direction.

[0015] The beneficial effects of the present invention are as follows: first, through the cooperation of the fixed frame and the sliding groove on the mounting bracket and the second driving frame and the first sliding key inside the lifting groove, the LED display screen installed on the mounting bracket can be telescopically moved back and forth, and the damping shaft inserted between the first driving frame and the second driving frame can enable the two to be positioned, making it convenient for people to adjust the moving distance of the display screen.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 A movable LED display screen includes a fixed frame 1, the fixed frame 1 is in a hollow state, and fixed columns 2 are vertically inserted into the fixed frame 1, and a connecting frame 4 is provided between the fixed columns 2;

[0023] A sliding groove 3 is provided on the fixed column 2, and a second driving frame 7 is provided in the sliding groove 3, and the other end of the second driving frame 7 is positioned on the outside of the mounting bracket 5 through the mounting hinge 71, and a lifting groove 51 is provided on the mounting bracket 5, and a first driving frame 6 is provided on one side of the lifting groove 51, and the other end of the first driving frame 6 passes through the lifting groove 51 and is connected to the first sliding key 61.

[0024] The other end of the first driving frame 6 is fixed to the bottom of the fixed column 2 through a mounting hinge, and a damping shaft 8 is transversely mounted at the middle intersection of the first driving frame 6 and the second driving frame 7 .

[0025] At the same time, the mounting bracket 5 is also hollow, and mounting plates 53 are mounted at the four inner corners of the mounting bracket 5 by fixing screws 52 , and positioning holes 54 are opened on the mounting plates 53 .

[0026] In addition, when the other ends of the first sliding key 61 and the second driving frame 7 are respectively at the bottom of the lifting slot 51 and the sliding slot 3 , the first driving frame 6 and the second driving frame 7 are in a 90° crossing state.

[0027] Furthermore, when the other ends of the first sliding key 61 and the second driving frame 7 are located at the tops of the lifting slot 51 and the sliding slot 3 respectively, the first driving frame 6 and the second driving frame 7 are in a retracted state.

[0028] Moreover, when the damping shaft 8 is moved by the first driving frame 6 and the second driving frame 7 , the damping shaft 8 moves back and forth in a straight line in the horizontal direction.

[0029] In this embodiment, the fixing frame 1 is first fixed to the wall by fixing screws, and then two fixing columns 2 are inserted into the fixing frame 1 in the vertical direction, and the connecting frame 4 is inserted between the fixing columns 2 to facilitate fixing and stabilization.

[0030] Then, a sliding groove 3 is opened on the fixed column 2, and a second driving frame 7 that can slide up and down is placed in the sliding groove 3, and the second driving frame 7 is placed at the bottom of the sliding groove 3. Then, the first driving frame 6 is installed on the inner side of the fixed column 2 through a hinge, and then the mounting bracket 5 is assembled.
