DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides Figure 1-6A new type of mask shown in the figure comprises a mounting frame 1, side light shielding plates 2 are integrally formed on the left and right sides of the front end of the mounting frame 1, a shielding cover 7 is arranged on the top between the two side light shielding plates 2, a mounting plate 3 is fixedly connected to the upper front end of the left side of the mounting frame 1, a motor 4 is detachably connected to the left side of the mounting plate 3, a first rotating shaft 5 is detachably connected to the output end of the motor 4, a second bearing 19 movable end is detachably connected to the end of the first rotating shaft 5 away from the motor 4, a fixing ring 18 is fixedly connected to the fixed end of the second bearing 19, the fixing ring 18 is fixedly connected to the upper front end of the right side of the mounting frame 1 at the lower right side, the fixing ring 18 and the mounting plate 3 are horizontally arranged on the same horizontal plane, two welded rotating rings 6 are evenly distributed on the first rotating shaft 5, the outer walls of the two rotating rings 6 are fixedly connected to shielding covers 7, the shielding covers 7 are arranged on the top of the mounting frame 1, the two rotating rings 6 are fixedly connected to the rear end of the shielding covers 7, and the shielding covers 7 can rotate between the two side light shielding plates 2. The model of motor 4 is ZGB37RG, and its internal structure and working principle are both existing technologies. Motor 4 drives the first rotating shaft 5 to rotate, and the mounting plate 3 is used for connecting the motor 4, one end of the first rotating shaft 5 and the mounting frame 1. The fixing ring 18 and the second bearing 19 are used for connecting the other end of the first rotating shaft 5 and the mounting frame 1. The movable end of the second bearing 19 rotates with the first rotating shaft 5 to improve the stability of the rotation process. The two rotating rings 6 rotate with the first rotating shaft 5 to drive the shielding cover 7 to rotate between the two light measuring plates 2 within an angle range of -90°-90°. During the rotation process, the shielding cover 7 and the two light measuring plates 2 are kept surrounding the mounting frame 1, so that it can adapt to different light blocking angles while keeping the three sides around the LED display screen opaque.

[0028] A slide groove 8 is provided in the middle of the top of the shielding cover 7, and a slide rod 9 is provided in the slide groove 8, both ends of which are fixedly connected to the shielding cover 7. A slider 10 is sleeved on the slide rod 9, and the slider 10 can slide in the slide groove 8. A push plate 11 is fixedly connected to the top of the slider 10, and the push plate 11 is provided on the top of the shielding cover 7. The push plate 11 and the counterweight 12 can both slide on the top of the shielding cover 7, and the counterweight 12 is detachably connected to the front end of the push plate 11 near the middle. When the shielding cover 7 rotates upward, the bottom of the counterweight block 12 is tilted from the horizontal plane, resulting in a shift in the center of gravity. The counterweight block 12 moves backward under the influence of gravity, and the push plate 11 moves backward with the counterweight block 12. The slider 10 moves backward with the push plate 11 under the limit of the slide bar 9. The slide bar 9 limits the moving trajectory of the slider 10, thereby limiting the moving trajectory of the counterweight block 9, driving the push plate 11 to push back the accumulated materials on the top of the shielding cover 7, such as snow, to avoid the accumulation of new reflective points on the shielding cover 7, thereby reducing the risk of obstacles to the viewing of the LED display screen. The shielding cover 7 and the side light blocking plate 2 are both sprayed with matte black oil.

[0029] Two rotating grooves distributed on the left and right are provided at the bottom of the slider 10, and rollers 20 are arranged in the two rotating grooves. A second rotating shaft 13 is commonly penetrated by the center of the sides of the two rollers 20. The left and right ends of the second rotating shaft 13 are respectively detachably connected with the movable ends of the first bearing 14. A polishing groove 15 for the rolling of the two rollers 20 is provided at the bottom of the slide groove 8. A through hole for communicating with the second rotating shaft 13 is provided at the lower left side of the slider 10, and mounting holes for detachably connecting with the fixed ends of the two first bearings 14 are respectively provided at the lower left and right sides of the slider 10. To summarize, the shielding cover 7 rotates upward, the counterweight 12 slides backward, the shielding cover rotates downward, the counterweight 12 moves forward, and the slider 10 moves with the counterweight 12 and the push plate 11. During the movement of the slider 10, the roller 20 with rubber as the surface material rotates on the two polishing grooves 15 at the bottom of the slider 10. At the same time, the two ends of the second rotating shaft 13 fixedly connected to the center of the roller 20 are connected to the slider 20 through the second bearing 19, making the rotation smoother, reducing the friction during the movement of the slider 20, and making the sliding of the slider 10, the push plate 11, and the counterweight 12 smoother, thereby improving the pushing and removal efficiency.

[0030] The inner wall of the installation frame 1 is detachably connected with a concave polygonal panel 16 at the front, and eight perforated mounting pieces 17 are evenly distributed at the back of the inner wall of the installation frame 1. The eight perforated mounting pieces 17 are fixedly connected to the installation frame 1. The concave polygonal panel 16 is composed of a plurality of arranged concave polygons, and a space for installing LED lamp beads is reserved in the arrangement. The geometric shape of the concave polygonal pyramid helps to disperse and reflect light. Through its multiple inclined surfaces, light can be reflected from one surface to another, reducing the proportion of light directly emitted. This continuous reflection process increases the propagation path of light in the coating, thereby improving the light absorption efficiency. The concave polygonal panel 16 is sprayed with matte black oil. Due to its dark color property, matte black oil has a strong absorption capacity for light. In the coating of matte black oil, light is not easily reflected directly, but is absorbed in large quantities, which enhances the absorption of light and makes the mask darker.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
