Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 to Figure 5 In the embodiment of the utility model, an outdoor LED screen installation display stand includes a base 1, a support rod 2 is fixedly connected to the base 1, a mounting plate 4 is fixedly connected to the support rod 2, a back plate 5 is fixedly connected to the mounting plate 4, a heat-conducting layer 18 is fixedly connected to one side of the back plate 5, and a protective shell 24 is fixedly connected to the other side of the back plate 5. A heat-conducting fin 25 is arranged in the protective shell 24, and the heat-conducting fin 25 is connected to the heat-conducting layer 18. Air outlets 26 are arranged on both sides of the protective shell 24. The back plate 5 is fixedly connected to the heat-conducting layer 18. An air guide port 19 is provided between the heat fins 25, and a fan assembly is installed in the air guide port 19. A shaft cylinder 8 is fixedly connected to the top of the back plate 5, a rotating shaft 9 is rotatably connected in the shaft cylinder 8, and a traction hook 10 is fixedly connected to the rotating shaft 9. A fixed block 6 is fixedly connected to the back plate 5, a first fixed shaft 7 is fixedly connected in the fixed block 6, a mounting hook 13 is rotatably connected to the first fixed shaft 7, an LED screen 11 is fixedly connected to the mounting hook 13, and a second fixed shaft 12 is fixedly connected to the LED screen 11. The second fixed shaft 12 is rotatably connected to the traction hook 10. The utility model supports the mounting plate 4 through the base 1 and the support rod 2. When the LED screen 11 needs to be installed, the mounting hook 13 at the bottom of the LED screen 11 is first hooked on the first fixed shaft 7, and then the LED screen 11 is rotated so that the back of the LED screen 11 is rotated and pressed against the heat conductive layer 18. Then, the traction hook 10 is driven to rotate through the rotating shaft 9, so that the traction hook 10 is rotated and fastened to the second fixed shaft 12, and the installation and fixation of the LED screen 11 can be completed. Then, when the LED screen 11 is working, the equipment absorbs the heat dissipated by the LED screen 11 through the setting of the heat conductive layer 18 and conducts it to the heat conductive fins 25. At the same time, the gas between the back plate 5 and the LED screen 11 is sucked into the protective shell 24 through the fan assembly, and then the gas in the protective shell 24 flows out along the heat conductive fins 25, and is finally discharged from the air outlet 26. In the process, the heat dissipated from the heat conductive fins 25 is absorbed and discharged.

[0021] In one case of this embodiment, see Figure 1 to Figure 5A protective pad 17 fixedly connected to the back plate 5 is provided between the back plate 5 and the LED screen 11. The utility model fills and protects the space between the back plate 5 and the LED screen 11 through the protective pad 17, thereby avoiding damage to the LED screen 11 shell caused by rigid contact between the LED screen 11 and the back plate 5.

[0022] In one case of this embodiment, see Figure 1 to Figure 5 The bottom of the base 1 is fixedly connected with a universal wheel 3. The utility model realizes the free movement of the device through the arrangement of the universal wheel 3.

[0023] In one case of this embodiment, see Figure 1 to Figure 5 One end of the rotating shaft 9 passes through the shaft tube 8 and is fixedly connected to a rocker arm 14, to which a handle 15 is fixedly connected, and an elastic buckle 16 is fixedly connected to the back plate 5, and the elastic buckle 16 cooperates with the rocker arm 14. The utility model drives the rocker arm 14 to rotate by pulling the handle 15, and the rocker arm 14 drives the rotating shaft 9 to rotate. At the same time, the rocker arm 14 is elastically clamped and fixed by the cooperation between the elastic buckle 16 and the rocker arm 14.

[0024] In one case of this embodiment, see Figure 1 to Figure 5 The fan assembly includes a mounting frame 21 fixedly connected to a protective shell 24, a motor 22 fixedly connected to the mounting frame 21, a fan blade 23 fixedly connected to the output shaft of the motor 22, a filter 20 fixedly connected to the air guide port 19, the fan assembly installs and fixes the motor 22 through the mounting frame 21, and drives the fan blade 23 to rotate through the motor 22, and then the gas between the back panel 5 and the LED screen 11 is sucked into the protective shell 24 through the rotation of the fan blade 23.

[0025] The working principle of the utility model is as follows: the utility model supports the mounting plate 4 through the base 1 and the support rod 2. When the LED screen 11 needs to be installed, the mounting hook 13 at the bottom of the LED screen 11 is first hooked on the first fixed shaft 7, and then the LED screen 11 is rotated so that the back of the LED screen 11 is rotated and pressed against the heat conductive layer 18. At the same time, the rocker arm 14 is elastically clamped and fixed by the mutual cooperation of the elastic buckle 16 and the rocker arm 14, and then the rocker arm 14 is driven to rotate by pulling the handle 15, and the rocker arm 14 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the traction hook 10 to rotate, so that the traction hook 10 is rotated and fastened to The LED screen 11 can be installed and fixed on the second fixed axis 12. After that, when the LED screen 11 is working, the device absorbs the heat dissipated by the LED screen 11 through the setting of the heat-conducting layer 18 and conducts it to the heat-conducting fins 25. At the same time, the motor 22 is installed and fixed through the mounting frame 21. At the same time, the fan blades 23 are driven by the motor 22 to rotate, and then the gas between the back panel 5 and the LED screen 11 is sucked into the protective shell 24 through the rotation of the fan blades 23, and then the gas in the protective shell 24 flows out along the heat-conducting fins 25, and finally discharged from the air outlet 26. In this process, the heat dissipated from the heat-conducting fins 25 is absorbed and discharged.
