[0032] Referring to Figure 1 、 Figure 3 and Figure 4 , an embodiment provided by the present invention: a height-adjustable electronic information device, including a straight rod 1. A chute 10 is provided on the front side of the straight rod 1. The rear side of the bottom of the straight rod 1 is rotatably connected to a turntable connecting rod 21. The installation of the turntable connecting rod 21 facilitates the use by the operator. Fixed square blocks 22 are fixedly connected to both the left and right ends of the rear side of the straight rod 1. A fixed short rod 23 is fixedly connected to the middle of the right side of the left fixed square block 22. The right end of the fixed short rod 23 penetrates through the front side of the turntable connecting rod 21 and is engaged with the right fixed square block 22. The installation of the fixed short rod 23 makes the turntable connecting rod 21 not rotate by itself. A fixed rod 7 is fixedly connected to the inner top end of the straight rod 1. Connecting strips 26 are fixedly connected to both the left and right sides of the bottom end of the fixed rod 7. A fixed pulley 25 is fixedly connected to the bottom end of the connecting strip 26. A movable pulley 24 is arranged at the bottom end of the fixed pulley 25. By installing the movable pulley 24, the pulling force is made less than the gravity.

The moving mechanism 2 is used for the movement of the square plate 11. A frame 12 is installed on the outer side of the square plate 11. A railing 27 is fixedly connected to the middle of the frame 12. The frame 12 is used to strengthen the stability of the square plate 11. A protective box 5 is arranged at the middle and lower part of the rear side of the straight rod 1. A connecting plate 19 is engaged with the left side of the protective box 5. The right end of the front side of the connecting plate 19 is fixedly connected to the straight rod 1. The protective box 5 is used for the protection of the turntable connecting rod 21;

[0033] Specifically, by rotating the turntable connecting rod 21, the connecting rope 18 is wound around the front side of the turntable connecting rod 21. The connecting rope 18 is connected to the movable pulley 24 through the fixed pulley 25. One end of the connecting rope 18 is connected to the bottom of the fixed pulley 25, and the other end passes through the bottom of the movable pulley 24 and is wound around the top of the fixed pulley 25 again, and finally connected to the front side of the turntable connecting rod 21, so that the movable pulley 24 can move up and down inside the straight rod 1. Furthermore, the square box 14 connected by the connecting block 28 can move in the sliding groove 10. A square plate 11 is installed on the outer side of the square box 14, and a frame 12 is arranged on the outer side of the square plate 11 to make it more stable.

The engagement of the connecting block 28 prevents the turntable connecting rod 21 from rotating by itself. By opening and closing the connecting plate 19, the opening and closing of the protection box 5 are controlled to prevent unauthorized personnel from accidentally touching it.

[0034] Referring to Figure 1 , Figure 2 and Figure 5 , the moving mechanism 2 includes a sliding groove 201 opened on the outer side of the square box 14. Rotating rods 206 are rotatably connected to the front and rear sides inside the square box 14. A motor 202 is installed on the top of the square box 14. The output end of the motor 202 penetrates the square box 14 and is fixedly connected to the rear rotating rod 206. A driving sprocket 203 is fixedly connected to the middle of the rear rotating rod 206, and a driven sprocket 204 is fixedly connected to the middle of the front rotating rod 206. The driving sprocket 203 is in transmission connection with the driven sprocket 204 through a chain 205. The rotating rods 206 are used to fix the driving sprocket 203 and the driven sprocket 204. One side of the chain 205 is fixedly connected to the connecting column 20. A protection box 13 is installed outside the motor 202. Heat dissipation holes 17 are opened at the front and rear ends on the left side of the protection box 13. The protection box 13 is used for protecting and dissipating heat from the motor 202;

[0035] Specifically, by starting the motor 202, the driving sprocket 203 begins to rotate. The driving sprocket 203 is driven by the chain 205 to drive the driven sprocket 204 to rotate together. On the outer side of the chain 205, a connecting column 20 is installed. The connecting column 20 is connected to the square plate 11. The square plate 11 is placed outside the square box 14. The square box 14 is provided with a sliding groove 201, so that the square plate 11 can move through the sliding groove 201, enabling the square plate 11 to move around the square box 14, so that the information on the square plate 11 can be seen by more people, expanding the applicable range and visibility of the square plate 11. A protection box 13 is installed on the top of the square box 14 to prevent the motor 202 from being damaged, and heat dissipation holes 17 are provided to dissipate heat. The model of the motor 202 is M3508.

[0036] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in

[0037] Specifically, the support rod 4 is used to support the baffle 3. When someone needs to take shelter from the rain, they can stay here. The installation of the square plate 15 enables lighting equipment to be installed at its bottom, which can be turned on at night for illumination. The bottom plate 8 and the fixing blocks 9 at the bottom of the straight rod 1 make the straight rod 1 more stable, and screws can be inserted into the fixing holes 6.

[0038] Working principle: By rotating the turntable connecting rod 21, the connecting rope 18 is wound around the front side of the turntable connecting rod 21. The connecting rope 18 is connected to the movable pulley 24 through the fixed pulley 25. One end of the connecting rope 18 is connected to the bottom of the fixed pulley 25, and the other end passes through the bottom of the movable pulley 24 and is wound around the top of the fixed pulley 25 again, and finally connected to the front side of the turntable connecting rod 21, so that the movable pulley 24 can move up and down inside the straight rod 1, and further enable the square box 14 connected by the connecting square 28 to move in the chute 10. The square plate 11 is installed on the outer side of the square box 14, and a frame 12 is arranged on the outer side of the square plate 11 to make it more stable. Through the above process, it is possible to use the same force to pull a heavier information plate.

[0039] By turning on the motor 202, the driving sprocket 203 rotates. The driving sprocket 203 is driven by the chain 205 to drive the driven sprocket 204, causing the driven sprocket 204 to rotate. A connecting post 20 is installed on the outer side of the chain 205, which enables the square plate 11 to move through the sliding groove 201 opened in the square box 14, realizing the movement of the square plate 11 around the square box 14, so that the information on the square plate 11 can be observed by more people and the applicable range of the square plate 11 is expanded.
