Description

Technical Field

[0001] The utility model belongs to the field of display devices, and mainly relates to a cooling structure for an outdoor large-format display screen. Background Art

[0002] There are two types of large outdoor advertising screens. One is a temporarily erected large outdoor display screen, which is mostly used for temporary erection in outdoor activities and is convenient for assembly, disassembly and transportation. The other is an advertising display screen installed on a building, which is permanently fixed and mainly used for circulating and scrolling advertisements. The back panels of these outdoor display screens all adopt a frame structure as the support frame for the large-format display screen;

[0003] When the large-format outdoor display screen is continuously used for a long time, a large amount of heat will be generated. Especially in summer, due to the too high outdoor temperature and the long-term operation of the display screen, the electronic screen will overheat, which will affect the performance of the display screen. The backlight module of the display screen will be damaged due to overheating and malfunction, and the display life of the display screen will be shortened. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cooling structure for an outdoor large-format display screen aiming at the defects and deficiencies of the prior art, which can quickly blow away the heat dissipated from the back panel of the large-format display screen by means of blowing, so as to play a role in cooling.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] The cooling structure for the outdoor large-format display screen includes a large-format display screen, a support frame, an air curtain device and a U-shaped suspension member. The large-format display screen is arranged on one side of the support frame. The air curtain device is arranged on the top of the support frame. The air curtain device is hung on the top of the support frame through the U-shaped suspension member. The air curtain device is provided with an air inlet and an air outlet, and the air outlet is parallel to the back plate surface of the large-format display screen.

[0007] A plurality of U-shaped suspension members are arranged on the air curtain device body to drag the air curtain device body onto the top of the support frame.

[0008] Both ends of the U-shaped suspension member body are provided with hook-shaped hooks for hanging on the rod body of the support frame; holes are provided on the hooks of the U-shaped suspension member, holes are provided on the body of the U-shaped suspension member, and the holes on the hooks of the U-shaped suspension member are parallel to the holes on the body of the U-shaped suspension member; a limiting rod is further arranged on the U-shaped suspension member, and screw holes are provided at both ends of the limiting rod, and the screw holes at both ends of the limiting rod respectively correspond to the holes on the hooks of the U-shaped suspension member and the holes on the body of the U-shaped suspension member.

[0009] The air curtain device has an air inlet disposed at the top of the machine body, and an air outlet disposed at the bottom of the machine body. Inside the air curtain device, there are a controller, a motor, and a wind wheel. The controller is electrically connected to the motor. The rotating shaft of the motor is connected to the wind wheel, and the wind wheel is horizontally placed inside the air curtain device.

[0010] Advantages of the present utility model:

[0011] By using the blowing method, the heat dissipated from the backplane of the large-format display screen can be quickly blown away, thus playing a role in cooling.

[0012] The air curtain device is hung at the top of the support frame of the large-format display screen, and an easily detachable U-shaped suspension member is used, making it easy to operate during assembly and disassembly. Description of the Drawings

Detailed Description of the Preferred Embodiments

[0019] In order to make the objectives, technical solutions and advantages of the present utility model more clearly understood, the following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Refer to Figures 1-5As shown in the figure, the cooling structure for an outdoor large-format display screen includes a large-format display screen 1, a support frame 2, an air curtain device 3, and a U-shaped suspension member 4. The large-format display screen 1 is arranged on one side of the support frame 2. An air curtain device 3 is provided at the top of the support frame 2. The air curtain device 3 is hung on the top of the support frame 2 through the U-shaped suspension member 4. The air curtain device 3 is provided with an air inlet 5 and an air outlet 6, and the air outlet 6 faces parallel to the back plate surface of the large-format display screen 1.

[0021] During assembly, the air curtain device 3 is towed and hung at the top end of the support frame 2 through a number of U-shaped suspension members 4. The hook 11 at the top end of the U-shaped suspension member 4 is hooked on the rod body of the support frame 2. Then, the limiting rod 12 is horizontally placed on the hook 11 and the body of the U-shaped suspension member 4. Bolts are passed through the screw holes 14 at both ends of the limiting rod 12, the holes 13 of the hook 11 on the U-shaped suspension member 4 corresponding thereto respectively, and the holes 10 on the body of the U-shaped suspension member 4, so as to limit the rod body of the support frame 2 within the hook 11 at the top end of the U-shaped suspension member 4, playing a role of limiting and fixing.

[0022] Then, by connecting the power supply of the air curtain device 3, the controller 7 provided inside the air curtain device 3 controls the motor 8 to start, and the motor 8 drives the wind wheel 9 to rotate. At this time, air is sucked into the air curtain device 3 from the air inlet at the top of the air curtain device 3 and then blown out from the air outlet of the air curtain device 3;

[0023] The air outlet 6 at the bottom of the air curtain device 3 faces parallel to the back plate surface of the large-format display screen 1. The air blown out forms a relatively large-area air curtain. At the connection between the blown air curtain and the back plate of the large-format display screen 1, the heat generated on the back plate is taken away by the wind, so that the back plate of the large-format display screen 1 is cooled, and the overall service life of the large-format display screen is increased.

[0024] During disassembly, remove the bolts on the hook 11 of the U-shaped suspension member 4, take off the limiting rod 12, and then lift the air curtain device 3 to disengage the hook 11 of the U-shaped suspension member 4 from the rod body of the support frame 2, and then remove the air curtain device 3. The disassembly and assembly operations are both convenient, improving the convenience of operation.

[0025] The description and application of the present utility model are only illustrative and schematic, and do not intend to limit the scope of the present utility model to the above embodiments; it is completely possible to make deformations and changes to the disclosed embodiments here. For those ordinary technicians in the art, the replacement and equivalent various components of the embodiments are well-known. Those skilled in the art should also be clear that without departing from the spirit or essential characteristics of the present utility model, the present utility model can be implemented in other forms, structures, arrangements, proportions, and with other components, materials, and parts, and other deformations and changes can be made to the disclosed embodiments here without departing from the scope and spirit of the present utility model.
