In practical use, compared with traditional multimedia teaching all-in-one machines, this multimedia teaching all-in-one machine has the following beneficial effects:

[0014] First, by setting up structures such as a fixed screen, a movable screen, a slider, a screw, a screw sleeve, and a connecting rod, the screw and screw sleeve are rotated to make a threaded movement, which in turn causes the connecting rod to drive the movable screen to deflect and cooperate with the fixed screen. As a result, the device can expand the screen as a whole according to the needs of use when in use, and can be folded up when not in use, saving space.

[0015] Secondly, by setting up structures such as a sliding plate, wheels, sealing frame, lead screw, bevel gear ring, motor, and bevel gear, the motor drives the bevel gear and bevel gear ring to cooperate, thereby causing the lead screw to rotate and the sliding plate to make threaded motion, so that the wheels can rise and fall within the base. This makes the device easy to move by the wheels while the sliding plate can slide within the base, creating negative pressure between the suction cup and the floor, making the device stable when placed on the ground.

[0016] Finally, by setting up structures such as a support shaft, sliding ring, gear ring, motor, and gears, the motor drives the gears to rotate and the gear ring to cooperate, thereby making the turntable easy to rotate and allowing the entire screen to rotate to adjust the display angle.

[0029] The moving mechanism 3 includes a sliding plate 31, wheels 32, a sealing frame 33, a lead screw 34, a bevel gear ring 35, a motor 36, a bevel gear 37, a corrugated sleeve 38, a support ring 39, a sealing ring 310, and an annular groove 311. The sliding plate 31 is slidably connected to the base 1, and the wheels 32 are mounted on the sliding plate 31. The lead screw 34 is threadedly connected to the sliding plate 31, and the lead screw 34 and the base 1 are mounted via bearings. A bevel gear ring 35 is mounted on the outer side of the lead screw 34 via bearings. The motor 36 is fixedly mounted on the base 1, and its output end is rotatably connected to the base 1. A bevel gear 37 is welded to the output end, and the bevel gear 37 meshes with the bevel gear ring 35. A corrugated sleeve 38 is fixedly sleeved on the outer side of the lead screw 34. A support ring 39 is welded to the sliding plate 31, and the support ring 39 and the corrugated sleeve 38 are rotatably connected. By setting up the moving mechanism 3, the device can be easily moved while remaining stable on the ground.

[0030] A sealing frame 33 is adhered to the slide plate 31, and the sealing frame 33 is slidably connected to the base 1. By setting the sealing frame 33, the sealing performance between the slide plate 31 and the base 1 is increased.

[0031] The corrugated sleeve 38 is fitted with a sealing ring 310, and the support ring 39 has an annular groove 311, in which the sealing ring 310 is rotatably connected. The corrugated sleeve 38 and the support ring 39 are connected by the cooperation of the sealing ring 310 and the annular groove 311.

[0032] The rotating mechanism 4 includes a support shaft 41, an elastic rod 42, a limiting block 43, a limiting groove 44, a sliding ring 45, a support 46, a gear ring 47, a motor 48, a connecting sleeve 49, a limiting pin 410, and a gear 411. The support shaft 41 is welded to the base 1. The support shaft 41 and the turntable 5 are mounted via bearings. The elastic rod 42 is fixedly connected to the support shaft 41. The limiting block 43 is fixedly connected to the elastic rod 42. The base 1 has a limiting groove 44. The limiting block 43 is slidably connected within the limiting groove 44. The turntable 5 has a sliding ring 45 welded to it. A gear ring 47 is fixedly sleeved within the sliding ring 45. The motor 48 is fixedly mounted on the base 1. The rotating shaft of the motor 48 is rotatably connected to the base 1. A connecting sleeve 49 is fixedly sleeved on the outside of the rotating shaft. A gear 411 is welded to the connecting sleeve 49. The gear 411 meshes with the gear ring 47. By setting up the rotation mechanism 4, the overall display direction of the device can be easily adjusted by rotation.

[0033] The outer side of the sliding ring 45 is rotatably connected to a support 46, which is welded to the base 1 and slidably connected to the turntable 5. The support 46 provides auxiliary support for the turntable 5.

[0034] The connecting sleeve 49 has a sliding connection of a limiting pin 410, which is threadedly connected to the rotating shaft. The limiting pin 410 connects the connecting sleeve 49 and the rotating shaft.

[0035] The invention is used as follows: When in use, the motor 36 is started, driving the bevel gear 37 to rotate, which in turn rotates the bevel gear ring 35, causing the lead screw 34 to rotate. The rotation of the lead screw 34 and the sliding plate 31 create a threaded motion, causing the sliding plate 31 to drive the wheel 32 to slide within the base 1. This causes the suction cup 2 to detach from the ground, allowing the device to move to a different position via the wheel 32. When the device reaches a designated position, the motor 36 drives the sliding plate 31 to move upwards, causing the suction cup 2 to contact the ground. The sliding plate 31 continues to slide within the base 1, creating a negative pressure between the suction cup 2 and the floor, thus allowing the device to remain on the floor. When placed stably, the device is activated according to the desired display direction. The motor 48 drives the gear 411 to rotate. The rotation of the gear 411 and the gear ring 47 cause the sliding ring 45 to rotate. The rotation of the sliding ring 45 causes the turntable 5 to rotate. The turntable 5 drives the fixed screen 6 to rotate, allowing the entire screen to rotate and adjust the display angle. When the display screen is expanded, the screw 9 is manually rotated. The rotation of the screw 9 and the screw sleeve 10 cause the connecting rod 11 to deflect. The deflection of the connecting rod 11 causes the movable screen 7 to rotate, thereby expanding the entire screen. When not in use, it can be folded up, saving space.
