Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figures 1 to 6 shown, the present utility model provides a multimedia teaching device, including:

[0030] A base 1, on the top of the base 1 is fixedly installed a fixing frame 2, and on the outer surface of the fixing frame 2 is provided a vertical groove 3;

[0031] A driving mechanism, which is arranged on the left side of the top of the base 1;

[0032] A lifting mechanism, which is arranged on the top of the base 1;

[0033] Among them, the lifting mechanism includes an arc plate 4, on the outer surface of the front end of the arc plate 4 is movably sleeved a driven gear 5, on the outer surface of the driven gear 5 is meshed and connected a driving gear 29, on the back of the driven gear 5 is fixedly installed a rotating rod 6, the inside of the rotating rod 6 is movably sleeved with the outer surface of the front end of the arc plate 4, fixedly sleeved inside the other end of the rotating rod 6 is a round shaft 7, the outer surface of the rear end of the round shaft 7 is movably connected with a moving rod 8, the back of the moving rod 8 is movably connected with the front of the fixing frame 2, on the left and right sides of the top of the moving rod 8 are fixedly installed vertical rods 9, on the top of the back of the vertical rods 9 is fixedly installed a moving block 10, the outer surface of the moving block 10 is movably connected with the inside of the vertical groove 3, the rear end of the moving block 10 is fixedly installed with a connecting block 11, the number of the connecting blocks 11 is two, and between the two connecting blocks 11 is fixedly installed a display 12.

[0034] Since the driving gear 29 is meshed and connected with the two driven gears 5, when the driving gear 29 rotates, it will drive the two rotating rods 6 to rotate in the opposite direction through the two driven gears 5. At this time, the two circular shafts 7 will rotate in the opposite direction driven by the two rotating rods 6. Due to the design of the two circular shafts 7, at this time, the two circular shafts 7 will squeeze the inside of the moving rod 8 during the reverse rotation, causing the moving rod 8 to drive the two vertical rods 9 to move. Due to the limitation of the two vertical grooves 3, at this time, the two vertical rods 9 will drive the two moving blocks 10 to move upward. Subsequently, the two moving blocks 10 will drive the entire display 12 to move upward through the two connecting blocks 11.

[0035] Among them, the driving mechanism includes:

[0036] A driving motor 13, the bottom end of the driving motor 13 is fixedly connected to the left side of the top end of the base 1, and the other end of the output shaft of the driving motor 13 is fixedly sleeved with a rotating shaft 14, and the other end of the rotating shaft 14 is fixedly sleeved with the inside of the driving gear 29;

[0037] A support block 15, the bottom end of the support block 15 is fixedly connected to the top end of the base 1, and the inside of the support block 15 is movably sleeved with the outer surface of the rotating shaft 14.

[0038] When the driving motor 13 operates, at this time, the rotating shaft 14 will drive the driving gear 29 to rotate. Due to the design of the support block 15, it will be able to support the rotating shaft 14, making the rotating shaft 14 more stable during rotation.

[0039] Among them, fixed rods 16 are fixedly installed on both the left and right sides of the fixed frame 2. A vertical shaft 17 is movably sleeved inside the fixed rod 16, and a whiteboard 18 is movably sleeved on the outer surface of the vertical shaft 17.

[0040] Since the vertical shaft 17 is movably sleeved inside the fixed rod 16, the vertical shaft 17 can drive the whiteboard 18 to rotate along the inside of the fixed rod 16.

[0041] Among them, a fixed block 19 is fixedly installed at the rear of the top end of the base 1. A power motor 20 is fixedly installed at the top end inside the fixed block 19, and the other end of the output shaft of the power motor 20 is fixedly sleeved with a screw rod 21.

[0042] When the power motor 20 operates, at this time, the screw rod 21 will rotate.

[0043] Among them, a movable block 22 is threadedly sleeved on the outer surface of the screw rod 21. Long rods 23 are fixedly installed on both the left and right sides of the movable block 22, and the front surface of the long rods 23 is movably connected to the rear surface of the fixed frame 2.

[0044] Since the screw rod 21 is threadedly sleeved with the movable block 22, when the screw rod 21 rotates, it will drive the two long rods 23 to move through the movable block 22. Since the two long rods 23 are movably connected to the back surface of the fixed frame 2, the two long rods 23 can only move up and down along the back surface of the fixed frame 2.

[0045] Wherein, circular blocks 24 are fixedly installed at the front ends of the left and right sides of the long rod 23. A rotating shaft 25 is movably sleeved inside the circular block 24. The top end of the rotating shaft 25 is fixedly connected to the bottom end of the vertical shaft 17. Fixed rings 26 are movably sleeved at the top and bottom ends of the outer surface of the rotating shaft 25. The outer surface of the fixed ring 26 is fixedly connected to the outer surface of the fixed frame 2.

[0046] When the two long rods 23 move upward, at this time, the two circular blocks 24 will move upward along the outer surfaces of the two rotating shafts 25 driven by the two long rods 23. Since the two rotating shafts 25 are respectively movably sleeved with two groups of fixed rings 26, the two rotating shafts 25 can rotate around the movable sleeve joints with the two groups of fixed rings 26 as the axis. When the two rotating shafts 25 rotate, at this time, the two vertical shafts 17 will rotate driven by the two rotating shafts 25.

[0047] Wherein, a spiral groove 27 is formed on the outer surface of the rotating shaft 25. An extrusion block 28 is movably connected inside the spiral groove 27. The outer surface of the extrusion block 28 is fixedly connected to the inside of the circular block 24.

[0048] When the circular block 24 moves upward, at this time, the two groups of extrusion blocks 28 will move upward driven by the two circular blocks 24. At this time, the two groups of extrusion blocks 28 will extrude the inside of the two groups of spiral grooves 27 during the upward movement, thereby causing the two rotating shafts 25 to rotate.

[0049] The working principle and usage process of the present utility model:

[0050] When the teaching staff needs to adjust the height of the display 12, the teaching staff activates the drive motor 13 at this time. Then, the rotating shaft 14 will drive the drive gear 29 to rotate. Since the drive gear 29 is respectively meshed and connected with the two driven gears 5, the drive gear 29 will drive the two driven gears 5 to rotate in opposite directions with the two arc-shaped plates 4 as the axes. At the same time, the two driven gears 5 will drive the two rotating rods 6 to rotate in opposite directions. Then, the opposite ends of the two rotating rods 6 will respectively drive the two round shafts 7 to rotate in opposite directions. When the two round shafts 7 rotate in opposite directions, they will squeeze and push the inside of the moving rod 8, so that the moving rod 8 drives the two vertical rods 9 to move. At this time, the two vertical rods 9 will respectively drive the two moving blocks 10 to move. Due to the design of the two vertical grooves 3, the movement of the two moving blocks 10 will be limited, so that the two moving blocks 10 can only move up and down. At this time, the two moving blocks 10 will be driven by the two vertical rods 9 to move upward along the inside of the two vertical grooves 3. At the same time, the two moving blocks 10 will drive the entire display 12 to move upward through the two connecting blocks 11, thus realizing the function of adjusting the height of the display 12 according to the user's height.

[0051] Then, the teaching staff activates the power motor 20. At this time, the screw rod 21 will rotate. Since the outer surface of the screw rod 21 is threadedly sleeved with the inside of the movable block 22, when the screw rod 21 rotates, it will drive the movable block 22 to move. Then, the movable block 22 will drive the two long rods 23 to move at the same time. Since the two long rods 23 are both in contact with the back surface of the fixed frame 2, the movable block 22 can only drive the two long rods 23 to move upward along the outer surface of the fixed frame 2. At this time, the movable block 22 will drive the two round blocks 24 to move upward along the outer surfaces of the two rotating shafts 25 through the two long rods 23. At the same time, the two groups of extrusion blocks 28 will move upward under the drive of the two round blocks 24. Since the outer surfaces of the two groups of extrusion blocks 28 are respectively movably connected with the inside of the two groups of spiral grooves 27, when the two groups of extrusion blocks 28 move upward, they will squeeze and push the inside of the two groups of spiral grooves 27, thereby causing the two rotating shafts 25 to rotate in opposite directions with the movable socket joints with the two groups of fixed rings 26 as the axes. Then, the two rotating shafts 25 will drive the two whiteboards 18 to rotate in opposite directions through the two vertical shafts 17. Subsequently, the two whiteboards 18 will be unfolded during the reverse rotation, thus realizing the function of automatically unfolding the two whiteboards 18.
