[0028] Reference Figure 1-6 , a demonstration device that is easy to adjust for the development of computer network technology, includes a base plate 1, a sliding frame 10 is fixed on the upper end of the base plate 1, the sliding frame 10 is U-shaped, a sliding seat 13 is slidably connected between the sliding frames 10, the upper end of the sliding seat 13 is rotatably connected to the demonstration board 16, a support 22 is fixed to one side of the sliding seat 13, a sliding cavity is opened in the support 22, and a tooth groove 23 is opened at the bottom of the sliding cavity, an angle adjustment mechanism is connected between the demonstration board 16 and the support 22, and a height adjustment mechanism is connected between the sliding seat 13 and the sliding frame 10, a plurality of rollers 2 are installed at the lower end of the base plate 1, a sliding sleeve 3 is fixed to the lower end of the base plate 1, a sliding plate 5 is slidably connected in the sliding sleeve 3, a pad 6 is fixed to the lower end of the sliding plate 5, and a driving mechanism is connected to the pad 6. The angle adjustment mechanism is used to adjust the demonstration angle of the demonstration board 16, and the driving mechanism cooperates with the pad 6 to improve the stability of the sliding frame 10.

[0029] Specifically, the height adjustment mechanism includes a handle 8, a rotating shaft 7, a screw 12, a threaded sleeve 11 and a driving bevel gear 9. The two sides of the sliding frame 10 are rotatably connected with the screw 12, and the lower end of the screw 12 is fixed with a driven bevel gear. The lower end of the sliding frame 10 is rotatably provided with a handle 8, and the handle 8 is located in the sliding frame 10 and is fixed with a rotating shaft 7. Two driving bevel gears 9 are fixed on the rotating shaft 7, and the two driving bevel gears 9 are meshed with the corresponding driven bevel gears. Threaded sleeves 11 are fixed on both sides of the sliding seat 13, and the threaded sleeves 11 are sleeved on the screw 12. The rotation of the screw 12 drives the movement of the threaded sleeve 11, so that the height of the sliding seat 13 is adjusted, thereby adjusting the height of the demonstration board 16.

[0030] Specifically, the angle adjustment mechanism includes a connecting rod 17, a sliding block 20, an L-shaped connecting block 33, a connecting plate 30, a sliding tooth 35, a fastening bolt 34, a pad 31 and a first return spring 32. One side of the demonstration plate 16 is rotatably connected to the connecting rod 17, and the end of the connecting rod 17 away from the demonstration plate 16 is rotatably connected to the sliding block 20. An L-shaped connecting block 33 is fixed to one side of the upper end of the sliding block 20, and a fastening bolt 34 is threadedly connected to the L-shaped connecting block 33. A connecting plate 30 is fixed to the side wall of the L-shaped connecting block 33, and a sliding plate 30 is slidably connected to the connecting plate 30. The movable teeth 35 are engaged with the tooth grooves 23 at their lower ends. A pad 31 is fixed to the upper ends of the sliding teeth 35. A first return spring 32 is fixed between the pad 31 and the L-shaped connecting block 33. The fastening bolt 34 is located in the first return spring 32. The sliding of the sliding block 20 drives the connecting rod 17 to push the demonstration board 16, so that the angle of the demonstration board 16 is adjusted. The cooperation between the sliding teeth 35 and the tooth grooves 23 and the restriction of the fastening bolt 34 on the pad 31 prevent the sliding of the sliding block 20, thereby keeping the angle of the demonstration board 16 fixed.

[0031] The upper end of the base plate 6 is located on one side of the sliding plate 5 and the sliding sleeve 3 and is fixed with two symmetrical movable rods 29, and the movable rod 29 passes through the base plate 1. The upper end of the base plate 1 is located on one side of the sliding frame 10 and is fixed with a support rod 28. The cylinder 27 is installed on the support rod 28. The upper ends of the two movable rods 29 are jointly fixed with the connecting seat 25. The upper ends of the connecting seat 25 corresponding to the position of the movable rod 29 are rotatably connected to the driving rod 26. The upper ends of the two driving rods 26 are jointly rotatably connected to the rotating seat, and the rotating seat is long and fixed on the output shaft of the cylinder 27. The movable rod 29 is located between the upper end of the base plate 1 and the connecting seat 25 and is sleeved with a second return spring 24. The driving rod 26, the connecting seat 25 and the movable rod 29 are pushed by the cylinder 27 to move, so that the base plate 6 can be supported when the demonstration board 16 is in use, thereby better providing stability requirements.

[0032] More specifically, a rubber anti-slip pad 4 is fixed to the lower end of the backing plate 6 to enhance the stability of the sliding frame 10. The threaded sleeve 11 slides on the sliding frame 10 and fits against the side walls of the sliding frame 10, limiting its rotation. Guide posts 21 are fixed to both sides of the sliding block 20, which slide on supports 22. The sliding block 20 is located within the sliding cavity, and the guide posts 21 prevent it from moving up and down. A storage box 14 is inserted into the side walls of the sliding seat 13. A toggle head 15 is fixed to one end of the storage box 14. Two symmetrical positioning posts 19 are fixed to the outer wall of the storage box 14, and the positioning posts 19 are inserted into the sliding seat 13. Each positioning post 19 is fixed with a damping rubber ring 18. The storage box 14 is used to hold writing tools or projector operating tools. The positioning posts 19 cooperate with the damping rubber ring 18 to stabilize the storage box 14 on the sliding seat 13. The upper end of the screw 12 rotates on the sliding frame 10 through a bearing. A fixed block is fixed to the sliding frame 10 near the lower end of the screw 12. The screw 12 rotates on the fixed block near the driven bevel gear, so that the lower end of the screw 12 is limited.

[0033] Working Principle: When adjusting the height of the demonstration board 16, the handle 8 drives the rotating shaft 7, the driving bevel gear 9, and the driven bevel gear, causing the two screws 12 to rotate simultaneously. The two screws 12 also drive the threaded sleeve 11 to move. Since the threaded sleeve 11 is attached to the sliding frame 10, the threaded sleeve 11 cannot rotate and can only move linearly, causing the sliding seat 13 to drive the demonstration board 16 to adjust its height, so that the height of the demonstration board 16 can better meet the needs of the demonstration staff.

[0034] When adjusting the angle, by loosening the fastening bolt 34, the L-shaped connecting block 33 can be moved to drive the sliding block 20 to slide. The sliding block 20 is limited by the guide column 21 and cannot move up and down. When the sliding block 20 slides, the demonstration board 16 is driven to rotate on the sliding seat 13 through the connecting rod 17, so that the angle of the demonstration board 16 can be better viewed. When the sliding block 20 slides, the sliding teeth 35 continuously move in the tooth groove 23. The sliding teeth 35 can be driven to reset by the first return spring 32. When the position is determined, the fastening bolt 34 is tightened so that the fastening bolt 34 pushes the pad 31 downward, thereby causing the sliding teeth 35 to be stuck in the tooth groove 23. At this time, the sliding block 20 cannot slide, and the angle of the demonstration board 16 remains fixed.

[0035] The cylinder 27 pushes the rotating seat, so that the rotating seat drives the driving rod 26 to push the connecting seat 25 and the movable rod 29 downward, so that the pad 6 is supported on the ground, improving the overall support stability, so that the demonstrator is more stable when writing. When the demonstration board 16 is moved, the cylinder 27 is reset, so that the movable rod 29 is upward, the pad 6 leaves the ground, and the support of the roller 2 is restored, thereby facilitating the movement of the demonstration board 16.

[0036] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
