Description

Technical Field

[0001] This utility model relates to the field of LED light box technology, and in particular to a rotating flowing LED light box. Background Technology

[0002] LED light boxes are a new type of display device that uses LEDs as the light source. They consist of a box body, LED beads, a light-transmitting panel, and a display screen. Their core advantages lie in the low energy consumption, high brightness, and long lifespan of LED light sources, which allows for brighter colors and outstanding nighttime display effects. They are suitable for advertising, signage, art displays, and other scenarios.

[0003] With the development of technology, existing LED light boxes have rotation and mobility functions. The light box can rotate around a fixed axis (360 degrees at a constant speed). With the help of LED beads, the image on the light-transmitting panel produces a continuous dynamic visual effect as it rotates. The LED lights gradually light up or turn off point by point according to a preset trajectory, forming the effect of light and shadow "flowing" along the circumference.

[0004] During long-term use, existing rotating LED light boxes tend to accumulate dust due to their continuous rotation and frequent contact with air. This dust not only directly obscures the details of the advertising images (such as blurring the edges of text and graphics), but also significantly reduces the light transmittance. When the dust accumulates to a certain extent, the overall display brightness of the light box decreases, the image clarity is damaged, and it becomes difficult to attract attention effectively. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that the surface of the light box easily attracts dust from the environment. When the dust accumulates to a certain extent, the overall display brightness of the light box decreases, the image clarity is damaged, and it is difficult to attract attention effectively. Therefore, a rotating and flowing LED light box is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rotating flowing LED light box, comprising a mounting frame, a light box body, and a cleaning device, wherein the mounting frame is rotatably connected to the inner wall of the light box body, an LED light body is mounted on the mounting frame, advertising cloth is mounted on all four sides of the light box body, a driving component is provided between the mounting frame and the light box body for controlling the rotation of the light box body, and a cleaning device is provided on the mounting frame; The cleaning device includes a movable ring slidably connected to the surface of the mounting frame. Four guide blocks are fixedly connected to the surface of the lightbox, and a frame is slidably connected to the surface of the guide blocks. Multiple cleaning sections are provided on the frame for cleaning dust from the advertising cloth. Two connecting rods are fixedly connected to the surface of the frame, and the connecting rods are slidably connected to the inner wall of the movable ring. An adjustment component is provided on the surface of the mounting frame for controlling the movement of the movable ring. Through the above components, during use, the drive component can drive the lightbox to rotate. During the rotation of the lightbox, the frame can rotate synchronously. The frame drives the connecting rods to slide circumferentially within the connecting ring. When cleaning is required, the adjustment component controls the movement of the movable ring, which drives the connecting rods to move, allowing the frame to move within the guide blocks, thereby driving the cleaning sections to clean.

[0007] Preferably, the driving assembly includes a driving motor mounted on the surface of the mounting bracket, a gear fixedly connected to the output end of the driving motor, and a gear ring fixedly connected to the surface of the lamp housing. The gear meshes with the gear ring. Through the above components, when the driving motor is turned on, the driving motor can drive the gear to rotate, and the gear, in conjunction with the gear ring, can drive the lamp housing to rotate.

[0008] Preferably, the adjustment assembly includes an adjustment motor installed in the inner wall of the mounting frame, an adjustment screw rotatably connected to the inner wall of the mounting frame, one end of the adjustment screw being fixedly connected to the output end of the adjustment motor, and the adjustment screw being threadedly connected to the inner wall of the moving ring. By using the above components, the adjustment motor is turned on, and the adjustment motor drives the adjustment screw to rotate. The adjustment screw can drive the moving ring to move up and down on the surface of the mounting frame, thereby achieving adjustment.

[0009] Preferably, the connecting rod includes a rod body and a ball, the ball being rotatably connected to the surface of the rod body, and the ball sliding against the inner wall of the moving ring to achieve circular motion. Through the above components, the ball can reduce friction when sliding against the inner wall of the moving ring, thus ensuring operational stability.

[0010] Preferably, the cleaning unit includes two insert blocks fixed inside the frame. A cleaning brush is inserted into the surface of the insert blocks. A locking screw is threaded onto the inner wall of the frame. The locking screw is inserted into the inner wall of the cleaning brush. Through the above components, after the cleaning brush is inserted into the insert blocks, rotating the locking screw will allow the locking screw to be inserted into the inner wall of the cleaning brush, achieving a positioning effect.

[0011] Preferably, the insert is T-shaped.

[0012] Preferably, the bristles of the cleaning brush are made of nylon.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a cleaning device is installed, and the moving ring is moved by the adjusting component. This, in turn, moves the frame in the guide block via the connecting rod. Multiple cleaning cloths on the frame wipe the four sides of the lightbox in a targeted manner, which can remove surface dust in a timely manner. Dust obscures the details of the advertising pattern, while ensuring that the light transmittance of the advertising cloth is not affected. This effectively maintains the continuity of light and shadow and the clarity of the image when the lightbox rotates and flows, and reduces the phenomenon of decreased display effect due to dust accumulation.

[0014] In this invention, the connecting rod slides against the inner wall of the moving ring via a ball bearing, converting sliding friction into rolling friction. This significantly reduces friction between components and extends the service life of the device. At the same time, the ball bearing ensures that the rotation of the lightbox and the movement of the frame do not interfere with each other.

[0015] In this invention, the cleaning brush is connected to the frame via a T-shaped insert and fixed with a locking screw, which facilitates the periodic replacement of worn cleaning brushes and makes the overall disassembly and assembly operation convenient. Attached Figure Description

[0020] In this implementation scheme: During use, the drive component 4 can drive the light box body 2 to rotate. During the rotation of the light box body 2, the frame 53 can rotate synchronously. The frame 53 drives the connecting rod 54 to slide circumferentially in the connecting ring. When cleaning is required, the adjustment component 52 controls the moving ring 51 to move. The moving ring 51 drives the connecting rod 54 to move, allowing the frame 53 to move in the guide block 56, thereby driving the cleaning part 55 to clean.

[0021] Specifically, the drive assembly 4 includes a drive motor 41 mounted on the surface of the mounting bracket 1, a gear 42 fixedly connected to the output end of the drive motor 41, and a gear ring 43 fixedly connected to the surface of the lamp housing 2, with the gear 42 meshing with the gear ring 43.

[0022] In this implementation scheme: when the drive motor 41 is turned on, the drive motor 41 can drive the gear 42 to rotate, and the gear 42, in conjunction with the gear ring 43, can drive the lamp box 2 to rotate.

[0023] Specifically, the adjustment assembly 52 includes an adjustment motor 521 installed in the inner wall of the mounting bracket 1, an adjustment screw 522 rotatably connected to the inner wall of the mounting bracket 1, one end of the adjustment screw 522 being fixedly connected to the output end of the adjustment motor 521, and the adjustment screw 522 being threadedly connected to the inner wall of the moving ring 51.

[0024] In this implementation scheme: Turn on the adjusting motor 521, the adjusting motor 521 drives the adjusting screw 522 to rotate, the adjusting screw 522 can drive the moving ring 51 to move up and down on the surface of the mounting bracket 1 to achieve adjustment.

[0025] Specifically, the connecting rod 54 includes a rod body 541 and a ball 542. The ball 542 is rotatably connected to the surface of the rod body 541. The ball 542 slides against the inner wall of the moving ring 51 to achieve circular motion. When the ball slides against the inner wall of the moving ring 51, it can reduce friction and ensure the stability of operation.

[0026] Specifically, the cleaning unit 55 includes two insert blocks 553 fixed inside the frame 53. A cleaning brush 552 is inserted into the surface of the insert block 553. A locking screw 551 is threadedly connected to the inner wall of the frame 53. The locking screw 551 is inserted into the inner wall of the cleaning brush 552. The insert block 553 is T-shaped. The bristles of the cleaning brush 552 are made of nylon.

[0027] In this implementation scheme: after the cleaning brush 552 is inserted into the insert block 553, the locking screw 551 is rotated, and the locking screw 551 can be inserted into the inner wall of the cleaning brush 552 to achieve the positioning effect.

[0028] Working principle: During rotation, the drive motor 41 is turned on, which drives the gear 42 to rotate. The gear 42, in conjunction with the gear ring 43, drives the light box 2 to rotate on the mounting frame 1. The LED light body 6 illuminates the advertising cloth 3. During the rotation of the light box 2, the frame 53 is simultaneously rotated, which in turn drives the connecting rod 54 to rotate. The ball bearings in the connecting rod 54 slide against the inner wall of the moving ring 51 to achieve circumferential motion, which reduces friction. When cleaning is required, the adjusting motor is turned on. The motor 521 drives the adjusting screw 522 to rotate. The adjusting screw 522 can drive the moving ring 51 to move on the surface of the mounting bracket 1. When the moving ring 51 moves, it pushes the frame 53 to move in the guide block 56 through the two connecting rods 54, and drives the cleaning brush 552 to perform a dust cleaning operation. When the cleaning brush 552 is replaced, simply rotate the locking screw 551. After the locking screw 551 moves out of the inner wall of the cleaning brush 552, the cleaning brush 552 can be removed from the insert block 553 to achieve disassembly and replacement.
