Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0022] like Figures 1 to 3 As shown, an advertising media display screen includes a fixed base plate 1. Fixed ear plates 4 are fixedly connected to each of the four corners of the fixed base plate 1. A corrugated telescopic frame cover 2 is fixedly connected to the edge of the outer surface of the fixed ear plates 4. A display screen body 3 is fixedly connected to the side of the corrugated telescopic frame cover 2 away from the corrugated telescopic frame cover 2. Connecting ears 15 are fixedly connected to both sides of the middle of the side of the fixed base plate 1 near the display screen body 3. A connecting shaft 6 is rotatably connected to the center of one side of the two connecting ears 15. Rotating ears 5 are fixedly connected to both sides of the connecting shaft 6. One end of the two rotating ears 5 is fixedly connected to both sides of the middle of the back of the display screen body 3. A driven worm gear 7 is fixedly connected to the middle of the connecting shaft 6. A worm support frame 8 is fixedly connected to the center of the side of the fixed base plate 1 near the display screen body 3. A driving worm 9 is rotatably connected to the center of one side of the worm support frame 8. The middle of the driving worm 9 meshes with the driven worm gear 7. A servo motor 10 is fixedly connected to the center of the top of the worm support frame 8. The output end of the servo motor 10 is fixedly connected to one end of the driving worm 9.

[0023] As an optional technical solution of this utility model, the size of the display body 3 is adapted to the size of the fixed base plate 1, the size of the edge of the display body 3 is adapted to the size of the outer wall of the corrugated telescopic frame cover 2, and the length of the corrugated telescopic frame cover 2 when it is in the telescopic middle position is adapted to the distance between the display body 3 and the fixed base plate 1 when they are parallel. By wrapping the fixed base plate 1 and the display body 3 with the corrugated telescopic frame cover 2, the transmission structure can be effectively protected, and airflow can be prevented from entering and causing shaking, thereby improving the stability of the connection.

[0024] As an optional technical solution of this utility model, a connecting piece 12 is fixedly connected to the middle of both sides of the fixed base plate 1 near the edge of the display screen body 3. A rotating shaft 13 is rotatably connected to the center of one side of the two connecting pieces 12. A guide sprocket 14 is fixedly connected to the middle of the two rotating shafts 13. A connecting chain 11 is fixedly connected to the top and bottom of both sides of the back of the display screen body 3. The middle of the connecting chain 11 is connected to the guide sprocket 14. The connecting chain 11 is guided by the guide sprocket 14, and the connecting chain 11 pulls the upper and lower sides of the back of the display screen body 3. This allows the connecting chain 11 to slide along the guide sprocket 14 as the display screen body 3 rotates. The stability can be improved by pulling the connecting chain 11 closer to the sides.

[0025] As an optional technical solution of this utility model, the length of the connecting chain 11 is greater than the distance between the two ends of the connecting chain 11 and the connection point of the display screen body 3, and the center of the rotating shaft 13 corresponds to the center of the connecting shaft 6, so that the rotating shaft 13 and the connecting shaft 6 have a synchronous rotation center, thereby improving the stability during flipping.

[0026] As an optional technical solution of this utility model, the distance between the edge of the guide sprocket 14 and the surface of the fixed base plate 1 is smaller than the distance between the display body 3 and the fixed base plate 1. When the display body 3 and the fixed base plate 1 are parallel, the guide sprocket 14 is connected to the middle of the connecting chain 11, thereby preventing the guide sprocket 14 from interfering with and blocking the display body 3 from flipping. Moreover, the guide can enable the connecting chains 11 on both sides to provide tension.

[0027] The following steps are required to use this advertising media display screen:

[0028] 1) The servo motor 10 drives the drive worm 9 to rotate, which in turn drives the driven worm wheel 7 to rotate, thereby driving the connecting shaft 6 to rotate;

[0029] 2) The rotation of the connecting shaft 6 drives the two rotating ears 5 to rotate, which in turn drives the display screen body 3 to reverse, thereby realizing the angle adjustment of the display screen body 3;

[0030] 3) The angle of the display body 3 is rotated, which causes the corrugated telescopic frame 2 to extend and retract up and down. The corrugated telescopic frame 2 wraps around the fixed base plate 1 and the display body 3, which can effectively protect the transmission structure and prevent airflow from entering and causing shaking, thus improving the stability of the connection.

[0031] 4) The connecting chain 11 is guided by the guide sprocket 14, and the connecting chain 11 pulls the upper and lower sides of the back of the display body 3, so that the connecting chain 11 can slide along the guide sprocket 14 as the display body 3 flips. The stability can be improved by pulling the connecting chain 11 closer to the sides.

[0032] In summary, the servo motor 10 drives the drive worm gear 9 to rotate, which in turn drives the driven worm wheel 7 to rotate, thereby driving the connecting shaft 6 to rotate. This, in turn, drives the two rotating ears 5 to rotate, causing the display screen body 3 to reverse, thus achieving angle adjustment of the display screen body 3. This can adapt to angle adjustments at different installation heights, and there is no need to loosen or tighten bolts, making adjustment convenient and quick. Furthermore, the corrugated telescopic frame cover 2, which wraps around the fixed base plate 1 and the display screen body 3, can effectively protect the transmission structure and prevent airflow from entering and causing shaking, thereby improving the stability of the connection. The connecting chain 11 is guided by the guide sprocket 14, and the connecting chain 11 pulls on the upper and lower sides of the back of the display screen body 3, allowing the connecting chain 11 to slide along the guide sprocket 14 as the display screen body 3 rotates. Pulling the connecting chain 11 closer to the sides improves stability.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
