Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically to an efficient heat dissipation device for LED displays. Background Technology

[0002] LED electronic displays are a type of display that controls semiconductor light-emitting diodes. They consist of tens of thousands to hundreds of thousands of semiconductor light-emitting diode pixels arranged evenly. Different materials can be used to manufacture LED pixels of different colors to display various information such as text, graphics, images, animations, market information, videos, and recorded signals. LED displays generate heat during use, so efficient heat dissipation devices are required.

[0003] Existing patent CN221008522U discloses a high heat dissipation LED display screen, belonging to the field of LED display screen technology. It includes: a housing structure consisting of a frame formed by several borders; multiple rear doors and door ribs are arranged on the inner side of the frame; the rear doors are arranged sequentially within the frame; door ribs are arranged between adjacent rear doors; at least one rear door is an air conditioner rear door, and an air conditioner is installed on the air conditioner rear door.

[0004] The aforementioned patents or existing heat dissipation devices have the following problems:

[0005] Existing heat dissipation devices use an air intake to blow outside air into the mounting frame, and then the heat sink blows the hot air out of the mounting frame, creating an airflow channel within the mounting frame. This helps to dissipate the heat generated by the LED display screen. However, the air contains a lot of dust, which is carried along with the air as it passes through the air intake into the mounting frame. Therefore, a protective mesh is installed at the air intake to filter the dust. However, most existing protective meshes are either non-removable or inconvenient to remove, which leads to them becoming clogged with dust over time, thus reducing the airflow. Utility Model Content

[0006] The purpose of this invention is to provide an efficient heat dissipation device for LED displays to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency heat dissipation device for an LED display screen, comprising a mounting frame, an air inlet on one side of the mounting frame, a heat dissipation vent on the other side of the mounting frame, an air intake on one side of the interior of the mounting frame, a heat dissipation vent on the other side, a detachable protective mesh inside the air inlet, the detachable protective mesh including a mounting plate, the mounting plate being assembled inside the air inlet, the protective mesh being provided on the mounting plate, a slot being provided on the edge of the air inlet, an insert plate being provided on the edge of the mounting plate, a latch being provided on the edge of the air inlet, a sliding connecting plate being assembled inside the mounting plate, a lever being provided on the connecting plate, a push plate being provided on the surface of the connecting plate, a locking plate being provided on the push plate, and an elastic connecting member being provided inside the mounting plate.

[0008] Preferably, the surface of the push block is on the same plane as the surface of the mounting frame.

[0009] Preferably, the surface of the lever is fixed with an anti-slip pad, which protrudes from the surface of the lever.

[0010] Preferably, at least two elastic connectors are provided, with the two elastic connectors located at the left and right ends of the push plate, respectively.

[0011] Preferably, the card is elongated.

[0012] Preferably, the outer surface of the push plate is in contact with the inner surface of the mounting plate.

[0013] Preferably, the length of the card plate is less than the length of the push plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the protective net needs to be disassembled and cleaned, the sliding block moves the connecting plate, which in turn moves the push plate to make the locking plate slide out of the slot, thereby releasing the limit on the mounting plate. Then, the mounting plate is rotated so that the insert plate rotates in the slot, and the mounting plate can be pulled out to disassemble the protective net and clean it. The disassembly process is relatively convenient. During installation, the insert plate is first inserted into the slot at an angle, and then the mounting plate is rotated into the air inlet. Under the action of the elastic connector, the locking plate is inserted into the slot, which is beneficial for the convenient installation of the protective net. Attached Figure Description

Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides an efficient heat dissipation device for LED displays, including a mounting frame 1, an air inlet 2 on one side of the mounting frame 1, a heat dissipation vent 3 on the other side of the mounting frame 1, an air inlet 4 on one side inside the mounting frame 1, a heat dissipation vent 5 on the other side, and a detachable protective mesh 6 inside the air inlet 2.

[0023] The LED display screen is installed in the mounting frame 1. The air inlet 4 and the heat sink 5 operate simultaneously. External air enters the mounting frame 1 through the air inlet 2 via the air inlet 4, and then the heat sink 5 blows the air inside the mounting frame 1 out through the heat dissipation vent 3, thus forming a heat dissipation airflow channel in the mounting frame 1. The heat generated by the LED display screen is efficiently dissipated through the airflow channel, resulting in a high heat dissipation effect.

[0024] Please see Figure 2 , Figure 3 and Figure 4 This utility model provides an efficient heat dissipation device for LED displays. The detachable protective net 6 includes a mounting plate 61. The mounting plate 61 is installed inside the air inlet 2. A protective net 62 is provided on the mounting plate 61. The protective net 62 is used to filter dust in the air, so that dust cannot pass through the protective net 62 and enter the mounting frame 1.

[0025] The air inlet 2 has a slot 63 on one side and a card slot 65 on the other side.

[0026] An insert plate 64 is embedded and fixed to the edge of the mounting plate 61. A sliding connecting plate 66 is fitted inside the mounting plate 61. A lever 67 is provided on the connecting plate 66. The surface of the lever 67 is flush with the surface of the mounting frame 1. An anti-slip pad 671 is fixed to the surface of the lever 67, protruding from the surface of the lever 67 to provide an anti-slip effect when the lever 67 is slidably moved. A push plate 68 is integrally formed on the surface of the connecting plate 66. A long strip-shaped retaining plate 69 is provided on the push plate 68. 9. The mounting plate 61 can be effectively prevented from tilting. The length of the clamping plate 69 is less than the length of the push plate 68, which can prevent the push plate 68 from sliding out of the mounting plate 61. Moreover, the outer surface of the push plate 68 is in contact with the inner surface of the mounting plate 61, which can effectively prevent the push plate 68 from shaking. The mounting plate 61 is provided with an elastic connector 610 inside. There are at least two elastic connectors 610. The two elastic connectors 610 are located at the left and right ends of the push plate 68, which can effectively prevent the push plate 68 from warping.

[0027] When the protective net 62 needs to be disassembled and cleaned, the sliding block 67 drives the connecting plate 66, causing it to slide along the inner wall of the mounting plate 61. Simultaneously, this drives the push plate 68, which in turn drives the locking plate 69, causing it to slide out of the latch 65, thus releasing the restriction on the mounting plate 61. Then, the mounting plate 61 is rotated, causing the insert plate 64 to rotate within the slot 63. The mounting plate 61 can then be pulled out to disassemble the protective net 62, allowing for its cleaning. Disassembly and cleaning are performed, and the disassembly process is relatively convenient. During installation, the insert plate 64 is first inserted into the slot 63 at an angle. Then, the mounting plate 61 is rotated and turned into the air inlet 2. Then, the sliding block 67 is slid to allow the locking plate 69 to slide into the mounting plate 61. At this time, the elastic connector 610 is deformed under force and generates elastic force. Under the action of the elastic connector 610, the push plate 68 is pushed and the locking plate 69 is inserted into the slot 65, so as to achieve the beneficial effect of convenient installation of the protective net 62.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
