Electronic information display boards are widely used in the fields of display, promotion, advertising, etc., and play a great role in the promotion of goods and the dissemination of information.

[0003] According to a Chinese patent with publication number CN219493587U, an electronic information display board is disclosed. After the utility model drives the damping telescopic rod A and the outer spring to unfold, the rotating limit frame drives the support rod to rotate through the bearing. After adjusting the electronic display board to a suitable display angle, the staff loosens the limit frame, so that the damping telescopic rod A and the outer spring drive the limit frame to contract, so that the side limit block A of the limit frame slides into the relative limit groove A. After the electronic display board is fixed, the appropriate angle adjustment of the electronic display board is completed, which is convenient for passers-by to view.

[0004] Regarding the above-mentioned disclosed patent content, since the electronic display screen will be exposed to the external environment when the electronic information display board is not in use, when an external object accidentally hits the electronic information display board, it is difficult to protect the electronic display screen, so the electronic display screen will be hit first. If the impact is strong, it may cause damage to the electronic display screen, making it difficult to continue using the electronic information display board, thereby reducing the service life of the electronic information board and reducing the protection effect of the electronic display screen.

The setting of the base 3 can support the bottom plate 1, and the setting of the anti-skid pad can improve the stability of the base 3. The protective component 9 includes a frame 901 and a storage cavity 909 arranged on the top of the bottom plate 1, and both sides of the interior of the frame 901 are provided with limiting grooves 903, and the interior of the limiting groove 903 is provided with limiting grooves. The movable plate 904 is connected between the two limit blocks 905, and the movable plate 904 is slidably connected to the limit groove 903 through the limit block 905. The top of the movable plate 904 is connected with a threaded column 902 through a bearing, and a rack 906 is provided at the bottom of the movable plate 904. When the movable plate 904 moves, it will drive the limit block 905 to slide inside the limit groove 903, thereby improving the stability of the movable plate 904 when moving, so as to ensure that the rack 906 is driven to move stably.

[0038] Specifically, the outer wall of the protective plate 911 is wrapped with a rubber sleeve, and the sum of the sizes of the two protective plates 911 is larger than the size of the electronic display screen 2. The setting of the rubber sleeve prevents external objects from colliding with the protective plate 911 and causing damage to the protective plate 911. At the same time, the protective plate 911 can block the electronic display screen 2 to protect the electronic display screen 2. The top of the threaded column 902 extends to the outside of the frame 901 and is connected to a turntable. The threaded column 902 is threadedly connected to the frame 901. When the electronic information display board needs to be used, the user can rotate the threaded column 902 through the turntable to move the threaded column 902 downward and drive the rack 906 to move downward.

[0039] Specifically, a cavity 912 is provided inside the frame 901, and two gear shafts 907 are provided inside the cavity 912 through bearings. A gear 908 is sleeved on the outer wall of the gear shaft 907. Both gears 908 are meshed with the rack 906. The rack 906 is adapted to the storage cavity 909. When the rack 906 moves down, it drives one gear 908 to rotate clockwise and the other gear 908 to rotate counterclockwise. When the gear 908 rotates, it drives the gear shaft 907 to rotate. One end of the gear shaft 907 extends It extends to the outer surface of the frame 901 and is connected to a rotating plate 910, and a protective plate 911 is installed at the bottom of the rotating plate 910. The protective plate 911 and the rotating plate 910 are both rotatably connected to the frame 901 through a gear shaft 907. When the gear shaft 907 rotates, it will drive the rotating plate 910 to rotate, and then drive the protective plate 911 to rotate, so as to adjust the position of the protective plate 911. A sponge block is provided on the back of the protective plate 911, so that the sponge block fits with the surface of the electronic display screen 2, thereby protecting the electronic display screen 2.

[0040] See also Figure 1-Figure 5 , movable shafts 5 are connected to the upper sides of the base plate 1 through bearings, and a bracket 4 is installed at one end of the movable shaft 5. The bracket 4 is rotatably connected to the base plate 1 through the movable shaft 5. The setting of the movable shaft 5 facilitates the rotation of the bracket 4, so that the angle of the bracket 4 can be adjusted. Slide grooves 10 are provided on both sides of the base plate 1, and a slider 7 is provided inside the slide groove 10. A support plate 8 is connected between the slider 7 and the bracket 4 through a rotating shaft. The slider 7 is slidably connected to the slide groove 10. When the bracket 4 rotates, it will pull the support plate 8, and the support plate 8 can drive the slider 7 to slide inside the slide groove 10, so as to improve the stability of the bracket 4 when it rotates.

[0041] Embodiment 2:

[0042] On the basis of the above-mentioned embodiment 1, since the angle adjustment of the bracket 4 is completed and its bottom is in contact with the ground, the bracket 4 needs to be limited to prevent the bracket 4 from rotating at will, so the following structure is set.

[0043] See also Figure 1-Figure 3A limiting screw 6 extending to the inside of the base plate 1 is installed on one side of the bracket 4. When the angle adjustment of the bracket 4 is completed, the user can rotate the limiting screw 6 and screw the limiting screw 6 into the bracket 4 and the base plate 1 to limit and fix the bracket 4 to prevent the bracket 4 from rotating at will, so that the bracket 4 can support the base plate 1.

[0044] The working principle of the utility model is as follows: first, when the electronic information display board is not used, the two protective plates 911 are attached to and shield the electronic display screen 2, so as to protect the electronic display screen 2 and prevent external objects from colliding with the electronic display screen 2 and causing damage to the electronic display screen 2 when not in use or in the process of carrying. When the electronic information display board needs to be used, the user can rotate the threaded column 902 through the turntable, so that the threaded column 902 moves down and drives the rack 906 to move down. When the rack 906 moves down, it drives one gear 908 to rotate clockwise and the other gear 908 to rotate counterclockwise. When the gear 908 rotates, it drives the gear shaft 907 to rotate, and then drives the two rotating plates 910 to rotate, and drives the protective plates 911 to rotate, so that the protective plates 911 are opened and no longer shield the electronic display screen 2, and the electronic display screen 2 can be used at this time;

[0045] Then rotate the limit screw 6 to unscrew one end of the limit screw 6 from the base plate 1, and then the bracket 4 can be rotated. When the bracket 4 rotates, it will drive the support plate 8 to rotate, and the support plate 8 will pull the slider 7 to slide inside the slide groove 10. When the angle adjustment of the bracket 4 is completed and its bottom is in contact with the ground, the user can screw the limit screw 6 into the base plate 1 to limit the bracket 4, and the bracket 4 can support the base plate 1.
