[0027] Please see Figures 1 to 7 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] An information technology teaching demonstration device includes: a rotating frame 1; a display screen body 2 is fixedly connected to one side of the rotating frame 1; a gantry frame 3 is provided on the side of the rotating frame 1 away from the display screen body 2; a protective box 4 is provided inside the gantry frame 3; a first rotating shaft 5 is provided on the display screen body 2 near the protective box 4; one end of the first rotating shaft 5 is fixedly connected to the rotating frame 1; the other end of the first rotating shaft 5 away from the rotating frame 1 passes through the protective box 4 and extends into the interior of the protective box 4; the first rotating shaft 5 is rotatably connected to the protective box 4; a limiting mechanism 6 is provided inside the protective box 4 to control the rotation of the display screen body 2; rotating mechanisms 7 for adjusting the height of the display screen body 2 are provided on both sides of the protective box 4; the user can control the first rotating shaft 5 to rotate 90° through the limiting mechanism 6; the first rotating shaft 5 drives the rotating frame 1; the rotating frame 1 drives the display screen body 2; thereby achieving the function of controlling the display screen body 2 to display in landscape and portrait modes.

[0029] like Figures 3 to 5As shown, the limiting mechanism 6 includes: a grooved wheel 8 is provided inside the protective box 4, the grooved wheel 8 is fixed to the outer surface of the first rotating shaft 5, a limiting wheel 9 is provided on one side of the grooved wheel 8, and a second rotating shaft 10 is fixedly connected to the center of the limiting wheel 9.

The rotation of the second rotating shaft 10 drives the limiting wheel 9, the limiting wheel 9 drives the extension plate 11, and the extension plate 11 drives the cylindrical block 12, causing the cylindrical block 12 to rotate. As the cylindrical block 12 rotates, it enters the groove of the grooved wheel 8, thereby driving the grooved wheel 8 to rotate 90°. When the cylindrical block 12 separates from the grooved wheel 8, the limiting wheel 9 limits the grooved wheel 8 through the arc groove of the grooved wheel 8, so that the first rotating shaft 5 is fixed after rotating 90°, thereby achieving the function of controlling the display screen body 2 to display in both horizontal and vertical modes. It can control the display screen body 2 to rotate 90° and limit the rotated display screen body 2, so that the display screen body 2 can achieve the function of displaying in both horizontal and vertical modes. Although the existing teaching display devices for information technology can adjust the height of the display board, they cannot control the rotation of the display board, so that the display board can only be displayed in horizontal mode.

[0030] like Figures 3 to 5 As shown, the power mechanism 13 includes: a worm gear 14 is provided on one side of the limiting wheel 9, the worm gear 14 is fixed to the outer surface of the second rotating shaft 10, a worm 15 is meshed on one side of the worm gear 14, and a third rotating shaft 16 is fixedly connected to the center of the worm 15; one end of the third rotating shaft 16 is rotatably connected to the protective box 4, and the other end of the third rotating shaft 16 passes through the protective box 4 and extends to the motor 17, the motor 17 is fixedly connected to the protective box 4, and the third rotating shaft 16 is fixedly connected to the output end of the motor 17. When the motor 17 is started, the output end of the motor 17 actuates the third rotating shaft 16, the third rotating shaft 16 drives the worm 15, the worm 15 rotates and drives the worm gear 14 to rotate, and the cooperation between the worm 15 and the worm gear 14 can achieve a self-locking function.

[0031] like Figure 6As shown, the rotating mechanism 7 includes: lifting blocks 18 fixedly connected to both sides of the protective box 4; internal threaded sleeves 19 fixedly connected inside the lifting blocks 18; screws 20 connected to the internal threads of the internal threaded sleeves 19; the bottom ends of the screws 20 are rotatably connected to the base plate 21; the top ends of the screws 20 penetrate the gantry frame 3 and extend to the first bevel gear 22; the first bevel gear 22 is fixedly connected to the screws 20; a dual-axis motor 23 is fixedly connected to the top center of the gantry frame 3; second bevel gears 24 are fixedly connected to the output ends of the dual-axis motor 23 on both sides; the second bevel gears 24 mesh with the first bevel gears 22. The dual-axis motor 23 is started. The output end of the dual-axis motor 23 drives the second bevel gear 24, the second bevel gear 24 drives the first bevel gear 22, the first bevel gear 22 drives the screw 20, and the screw 20 rotates while driving the lifting block 18.

The height of the display screen body 2 can be adjusted according to the needs, thereby achieving the goal of adjusting the height of the display screen body 2 according to the viewing angle of the viewer, which improves the practicality of the display screen body 2.

[0032] like Figure 1 and Figure 2 As shown, balance plates 26 are fixedly connected to both sides of the base plate 21. Both sides of the bottom of the balance plate 26 are provided with casters 27 with braking function. The casters 27 are fixedly connected to the balance plate 26, which makes it convenient for users to move and fix the device.

[0033] like Figure 1 As shown, structural plates 28 are provided on both sides of the bottom of the gantry frame 3. The structural plates 28 are fixedly connected to the gantry frame 3, the base plate 21 and the balance plate 26, which improves the overall structural strength of the device.

[0034] like Figure 1 As shown, a control box 25 with a storage battery is provided at the top center of the base plate 21. The control box 25 is fixedly connected to the base plate 21. The storage battery can not only provide power to the device, but also be connected to the power source through wires, which improves the flexibility of the device.

[0035] Working principle: Starting motor 17 activates the third rotating shaft 16, which in turn drives the worm gear 15. The rotation of the worm gear 15 drives the worm wheel 14. The cooperation between the worm gear 15 and the worm wheel 14 achieves a self-locking function. The worm wheel 14 drives the second rotating shaft 10, which in turn drives the limiting wheel 9. The limiting wheel 9 drives the extension plate 11, which in turn drives the cylindrical block 12, causing the cylindrical block 12 to rotate. As the cylindrical block 12 rotates, it enters the groove of the grooved wheel 8, causing the grooved wheel 8 to rotate 90°. When the cylindrical block 12 separates from the grooved wheel 8, the limiting wheel 9... The arc-shaped groove of the grooved wheel 8 limits the movement of the first rotating shaft 5, allowing it to rotate 90° and then be fixed. This enables the display screen body 2 to be used for both horizontal and vertical display. The display screen body 2 can be rotated 90°, and the rotated display screen body 2 is limited, allowing it to be used for both horizontal and vertical display. Existing information technology teaching display devices can adjust the height of the display board, but they cannot control the rotation of the display board, so the display board can only be displayed horizontally. However, some videos or pictures need to be displayed vertically, resulting in poor display effect of the device.

[0036] The dual-axis motor 23 is started. The output end of the dual-axis motor 23 drives the second bevel gear 24, the second bevel gear 24 drives the first bevel gear 22, the first bevel gear 22 drives the screw 20, and the screw 20 rotates while driving the lifting block 18. The lifting block 18 drives the protective box 4, and the protective box 4 drives the rotating frame 1 through the first rotating shaft 5. The rotating frame 1 drives the display screen body 2, thereby achieving the purpose of controlling the height of the display screen body 2. The height of the display screen body 2 can be adjusted according to the needs, thereby achieving the goal of adjusting the height of the display screen body 2 according to the viewing angle of the viewer, which improves the practicality of the display screen body 2.
