Description

Technical Field

[0001] This utility model belongs to the field of LED screen installation technology, and specifically relates to an installation mechanism for double-sided LED screens. Background Technology

[0002] LED screens are a new type of imaging electronic device made by arranging light-emitting diodes in sequence. Due to their high brightness, wide viewing angle, and long lifespan, they are being widely used in products such as outdoor advertising screens. Using LED light sources for lighting will first replace power-consuming incandescent lamps, and then gradually enter the entire lighting market, saving a lot of electricity. Recently, white LEDs have reached a point where a single LED consumes more than 1 watt of power and outputs 25 lumens of light, which also increases their practicality.

[0003] After installation, the height adjustment of a double-sided LED screen requires the cooperation of multiple people and is difficult to keep level, and it is prone to tilting. Fixed installation limits the adjustment of viewing angle and cannot adapt to different site requirements. During maintenance, ladders and other auxiliary tools are required, which increases safety risks. At the same time, the screen accumulates heat significantly when running under high load for a long time, which may cause accelerated light decay or color deviation of LED beads. Relying on active cooling fans will generate operating noise, which will interfere with the display environment. The thickened heat dissipation structure will compromise the thin and light characteristics of the screen and affect the aesthetics of the suspended installation.

[0004] To address the issues mentioned in the background above, a mounting mechanism for double-sided LED screens is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a mounting mechanism for double-sided LED screens, which has the advantages of height adjustment and improved heat dissipation efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mounting mechanism for a double-sided LED screen, including a housing, with steel wire ropes connected to the front and rear ends of the top of the housing, and a rotating drum connected to the end of the steel wire ropes away from the housing. A rotating rod 1 is fixedly sleeved inside the rotating drum on the left side, and a rotating rod 2 is fixedly sleeved inside the rotating drum on the right side. A gear 1 is fixedly sleeved at the front end of the surface of the rotating rod 1, and a gear 2 is fixedly sleeved at the front end of the rotating rod 2, with the left side of the gear 2 meshing with the right side of the gear 1. A motor is fixedly sleeved at the front end of the rotating rod 1. A bracket is rotatably sleeved at the front and rear ends of the rotating drum, and a top plate is bolted to the bottom of the bracket. A mounting mechanism is provided at the front and rear ends of the top plate, and a heat dissipation mechanism is provided in the middle of the inner wall of the housing.

[0007] The above technical solution works as follows: When the height of the display screen needs to be adjusted, the motor drives the first rotating rod to rotate, which in turn drives the first gear to rotate, which in turn drives the second gear to rotate, which in turn drives the second rotating rod to rotate. The rotating rods drive the rotating drum to rotate, and the rotating drum rotates to raise and lower the steel cable, thus moving the display screen up and down. The steel cable is pulled and released simultaneously on both sides to achieve raising and lowering. The operation is simple and intuitive, and the screen height can be precisely controlled to ensure that the screen remains horizontal during raising and lowering, avoiding screen tilt. The display height can be flexibly adjusted according to the needs of the site, and the hanging height can be quickly adjusted according to different site requirements and audience viewing angles, which not only optimizes the viewing experience but also facilitates later maintenance.

[0008] The present invention is further configured such that the heat dissipation mechanism includes a main board, which is bolted to the middle of the inner wall of the outer casing, and heat-conducting plates are bolted to the front, back and bottom of the main board, and heat dissipation fins are welded to the outer side of the heat-conducting plates.

[0009] The above technical solution employs a heat dissipation mechanism. When the display is working, heat is transferred to the heat conduction plate, which then transfers the heat to the heat dissipation fins. These fins help dissipate heat from the motherboard and the display, significantly improving heat dissipation efficiency without increasing screen thickness. The fins utilize natural convection to continuously dissipate heat, avoiding the noise issues of active cooling fans and extending the lifespan of LED components. The slim design maintains the overall aesthetics of the screen, making it particularly suitable for thickness-sensitive hanging installation scenarios. The maintenance-free passive heat dissipation method reduces subsequent maintenance costs and ensures stable performance even during prolonged high-brightness operation.

[0010] The present invention is further configured such that the installation mechanism includes a horizontal plate, which is bolted to the front and rear ends of the top plate, and a hanger rod is bolted to both sides of the top of the horizontal plate, and an expansion bolt is bolted to the top of the hanger rod.

[0011] The above technical solution involves using an installation mechanism, with hangers and expansion bolts to fix the mechanism to the indoor ceiling.

[0012] The present invention is further configured such that display screens are bolted to both sides of the motherboard.

[0013] The above technical solution allows for the display of screen information.

[0014] The present invention is further configured such that fixed pulleys are bolted to the front and rear ends of the top two sides and the bottom two sides of the top plate.

[0015] The above technical solution involves setting up a fixed pulley to change the direction of the wire rope, preventing it from contacting the top plate and causing damage.

[0016] The present invention is further provided that the heat dissipation fins are treated with acid-resistant aluminum.

[0017] By adopting the above technical solution, the heat dissipation efficiency of the heat sink fins can be improved by using acid-resistant aluminum treatment.

[0018] The present invention is further configured such that a frame is fitted around the outside of the motor.

[0019] The above technical solution, by setting up a frame, can stabilize the motor.

[0020] The present invention is further provided that the front side of the frame has heat dissipation holes.

[0021] The above technical solution involves providing heat dissipation holes to cool the motor.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. This utility model achieves lifting and lowering by simultaneously pulling and releasing steel wire ropes on both sides. The operation is simple and intuitive, and the screen height can be precisely controlled to ensure that the screen remains horizontal during lifting and lowering, avoiding screen tilt. The display height can be flexibly adjusted according to the needs of the site, and the suspension height can be quickly adjusted according to different site requirements and audience viewing angles, which not only optimizes the viewing experience but also facilitates later maintenance.

[0024] 2. This utility model significantly improves heat dissipation efficiency without increasing screen thickness. The fins utilize the principle of natural convection to continuously dissipate heat, which avoids the noise problem of active cooling fans and extends the service life of LED components. The thin and light design maintains the overall aesthetics of the screen and is particularly suitable for hanging installation scenarios where thickness is sensitive. The maintenance-free passive heat dissipation method reduces the later maintenance costs and ensures that the screen can maintain stable performance even when working at high brightness for a long time.
