[0019] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0020] Example 1

[0021] The visual communication device for exhibition hall described in this embodiment is as follows: Figures 1 to 4 As shown, it includes a vertically arranged back plate 4, and a flat plate 1 is horizontally fixed to the upper and lower ends of the front side wall of the back plate 4. The flat plate 1 has two pieces, which are horizontally fixed to the upper and lower ends of the front side wall of the flat plate 1 respectively;

[0022] A pressing plate 13 is arranged between the flat plate 1 and the light-transmitting plate 3. A through hole communicating front and back is opened on the flat plate 1. A sliding rod 11 is independently installed in the through hole. The sliding rod 11 is installed in the through hole and moves forward and backward along the hole depth direction of the through hole; the pressing plate 13 is vertically fixed to the rear end of the sliding rod 11. The pressing plate 13 is vertically fixed to the rear end of the sliding rod 11. When the sliding rod 11 moves, the pressing plate 13 is pushed to move together; a spring 10 is sleeved on the sliding rod 11 between the pressing plate 13 and the flat plate 1, one end of the spring 10 is fixed to the front side wall of the pressing plate 13, and the other end is fixed to the rear side wall of the flat plate 1; in the natural state of the spring 10, the pressing plate 13 presses the picture on the light-transmitting plate 3, and when the spring 10 is in the Under the action of the spring 10, the pressure plate 13 is continuously pushed backward to fix the picture on the light-transmitting plate 3; this paragraph of text as a whole constitutes a fixing component for fixing the picture. When the fixing component is used, the slide bar 11 is pulled outward, the spring 10 is compressed and deformed, and the picture is placed between the light-transmitting plate 3 and the pressure plate 13. The slide bar 11 is released, and the spring 10 loses the force and recovers the deformation, driving the pressure plate 13 to fix the picture on the front side of the light-transmitting plate 3; of course, the fixing component can also be fixed with a pull ring at the front end of the slide bar 11, which is convenient for the user to pull out the slide bar 11 for easy use; a groove is provided on the front side wall of the back plate 4, and a groove is provided on the rear side wall of the back plate 4;

[0023] A light-transmitting plate 3 is vertically fixed in the groove to seal the groove. The light-transmitting plate 3 is made of a transparent material. Light passes through the light-transmitting plate 3 and shines on the picture to improve the display effect of the picture. A light-emitting plate 6 is vertically installed in the groove on the rear side of the light-transmitting plate 3. The light-emitting plate 6 emits a light source. The light passes through the light-transmitting plate 3 and illuminates the picture.

[0024] Two freely rotating shafts 9 are installed in the groove, the upper ends of the rotating shafts 9 are fixed on the upper groove wall of the groove, and the lower ends are fixed on the lower groove wall of the groove. A blind hole is opened on the groove wall of the groove, and a bearing is installed in the blind hole. The outer ring of the bearing is fixed on the hole wall of the blind hole, and the rotating shaft 9 is fixed on the inner ring of the bearing. The bearing allows the rotating shaft 9 to rotate freely while being installed in the groove; the two rotating shafts 9 are respectively located on both sides of the light-emitting board 6, and the light-emitting board 6 is located between the two rotating shafts 9; blackout cloths 5 are stretched on the two rotating shafts 9, and the light-emitting board 6 is vertically arranged between the blackout cloths 5. The light-emitting board 6 is arranged between the blackout cloths 5, and the color of the light source is changed by blackout cloths 5 of different colors; a driving member for driving the rotating shaft 9 to rotate is installed on one of the rotating shafts 9, and the driving member is installed at the bottom of the back plate 4, and the power output end of the driving member is connected to the lower end of the rotating shaft 9, and the rotating shaft 9 is driven to rotate by the driving member. The driving member is a prior art, generally using Servo motor or motor; this paragraph of text as a whole constitutes an adjustment component for adjusting the color of the light-emitting panel 6. When the adjustment component is in use, the rotating shaft 9 is driven to rotate by the driving member. When the rotating shaft 9 rotates, the shading cloth 5 is driven to move, and the color of the light source is changed by the shading cloth 5 of different colors. The light emitted by the light-emitting panel 6 changes color after passing through the shading cloth 5, and the light of changed color is irradiated on the picture, thereby improving the display effect of the picture; of course; the adjustment component can also install the driving member on the top of the back plate 4, and accordingly, the upper end of the rotating shaft 9 is connected to the power output end of the driving member; a movable plate 2 is arranged between the two flat plates 1, and a brush 7 is fixed to the rear side wall of the movable plate 2, which pushes the movable plate 2 to slide between the two flat plates 1, and drives the brush 7 to move in front of the light-transmitting plate 3 to clean the dirt on the surface of the light-transmitting plate 3, thereby ensuring the light transmittance of the light-transmitting plate 3, and facilitating the display of the picture; this paragraph of text as a whole constitutes a cleaning component for cleaning the light-transmitting plate 3.

[0025] When this embodiment is used, the upper end of the picture is fixed on the front side wall of the light-transmitting plate 3 by a fixing component, and a light source is provided by the light-emitting panel 6. The light passes through the light-transmitting plate 3 and shines on the picture. In this process, the color of the light source is adjusted by the adjusting component to improve the display effect of the picture. After use, the light-transmitting plate 3 is cleaned by the cleaning component, so that the light-transmitting plate 3 has a good light transmission effect, thereby improving the display effect of the picture.

[0026] Example 2

[0027] This embodiment further illustrates the technology. Figure 3 As shown, a plurality of filters 8 of different colors are sewn on the shading cloth 5, and the filters 8 are sewn on the shading cloth 5. The color of light is changed by the filters 8 of different shapes and colors, and then the shading cloth 5 is driven to move by the rotation of the shaft 9, thereby changing the color and shape of the light spot irradiated on the picture, and realizing the movement and replacement of the light spot.

[0028] The filter 8 is a soft film filter, which is a prior art and is a filter made of a soft, transparent optical polymer film. The soft film filter can be sewn on the shading cloth 5 and can move together with the movement of the shading cloth 5.

[0029] Example 3

[0030] This embodiment further illustrates the technology. Slide blocks 12 are fixed at both upper and lower ends of the movable plate 2. Slide grooves for the sliding of the slide blocks 12 are opened on the two flat plates 1. The slide blocks 12 are inserted into the slide grooves and slide with them. The slide blocks 12 slide along the length direction of the slide grooves. The slide grooves limit the sliders 12 and thus regulate the moving direction of the movable plate 2.
