[0024] Please refer to the following specific embodiment of an LED display device. Figure 1-4 The system includes a support mechanism 1 and a display mechanism 2. The support mechanism 1 includes two first mounting seats 101. A sliding groove 102 is formed on the inner side of each first mounting seat 101. A first fixing bolt 103 is slidably connected to the surface of the sliding groove 102. A fixing nut 104 is provided on the inner side of each first mounting seat 101. A second hole block 105 is provided between the first fixing bolt 103 and the first mounting seat 101. A support seat 106 is fixedly connected to the surface of the second hole block 105. Two limiting seats 113 are mounted on the upper surface of the support seat 106. The surface of the 13 is provided with a guide groove 114, and the inner wall of the guide groove 114 is slidably connected with a limiting rod 115. The bottom of the support base 106 is fixedly connected with two card seats 116. The display mechanism 2 includes an LED display screen 201 located outside the first mounting base 101. The surface of the LED display screen 201 is provided with a plurality of light-emitting diode matrices 202. The back of the LED display screen 201 is fixedly connected with a first hole block 203 adapted to the limiting base 113. The back of the LED display screen 201 is fixedly connected with two first hanging blocks 204.

[0025] Through the above technical solution, the first fixing bolt 103 slides on the surface of the sliding groove 102, and then the second hole block 105 and the support base 106 are fixed and limited under the action of the fixing nut 104, thereby realizing the height adjustment of the display mechanism 2. The LED display screen 201 is snapped onto the surface of the card seat 116 by the first hanging block 204, and the first hole block 203 is snapped into the inner side of the limiting seat 113. Then the limiting rod 115 slides on the surface of the guide groove 114, thereby fixing the first hole block 203, thereby realizing the quick assembly and disassembly of the display mechanism 2.

[0026] First mounting plates 107 are provided on both sides of the first mounting base 101. First mounting holes 108 are provided on the surface of the first mounting plate 107. The first mounting base 101 is attached to the mounting surface, and then the first mounting base 101 is installed under the action of the first mounting plate 107 and the first mounting holes 108.

[0027] A transmission gear plate 109 is slidably connected inside the first mounting base 101, and a fixing nut 104 is fixedly connected to the surface of the transmission gear plate 109. A transmission shaft 110 is rotatably connected to the surface of the first mounting base 101. The surface of the transmission shaft 110 is provided with transmission teeth 111 adapted to the transmission shaft 110. An adjustment knob 112 is rotatably connected to the outer surface of the first mounting base 101, and the adjustment knob 112 is fixedly connected to one end of the transmission shaft 110. When the user holds the adjustment knob 112 and rotates it, the rotation of the adjustment knob 112 drives the transmission shaft 110 to rotate.

[0031] Its working principle is as follows:

[0032] Using the above technical solution, the first mounting base 101 is fitted to the mounting surface. Then, under the action of the first mounting plate 107 and the first mounting hole 108, the first mounting base 101 is installed. The user holds and rotates the adjustment knob 112. Rotation of the adjustment knob 112 drives the transmission shaft 110 to rotate. At this time, under the action of the transmission teeth 111, the transmission gear plate 109 moves, thereby driving the fixing nut 104 to adjust its height. Then, the first fixing bolt 103 slides on the surface of the sliding groove 102 and is then tightened. Aligned with and rotated with the fixing nut 104, the second hole block 105 and the support base 106 are fixed and limited under the action of the fixing nut 104, thereby realizing the height adjustment of the display mechanism 2. The LED display screen 201 is snapped onto the surface of the card holder 116 by the first hanging block 204, and the first hole block 203 is snapped into the inner side of the limiting seat 113. Then, the limiting rod 115 slides on the surface of the guide groove 114 to fix the first hole block 203, thereby realizing the quick fixation of the display mechanism 2.
