The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0034] Embodiment 1: Please refer to Figures 1-6 , the present invention provides a technical solution: an intelligent teaching telescopic teaching demonstration device with a teaching board, including a touch display screen 1, a speaker 4 is fixedly connected to the back of the touch display screen 1, an adjustment button 3 is fixedly connected to the bottom of the touch display screen 1, a pen slot 2 is fixedly connected to one end of the side of the touch display screen 1, a projection mechanism 5 is fixedly connected to the top of the touch display screen 1, a height adjustment mechanism 6 is fixedly connected to the bottom of the touch display screen 1, an angle adjustment mechanism 7 is fixedly connected to the back of the touch display screen 1, and a sliding mechanism 8 is fixedly connected to the bottom of the height adjustment mechanism 6;

[0035] The sliding mechanism 8 includes;

[0036] A bottom plate 81, and the bottom plate 81 is arranged at the bottom of the height adjusting mechanism 6;

[0037] A fixed bearing 86, and the fixed bearing 86 is arranged inside the bottom plate 81;

[0038] A friction block 84, a friction block 84 is fixedly connected to the bottom of the fixed bearing 86, an eighth fixed block 88 is fixedly connected to the top of the fixed bearing 86, and the fixed bearing 86 is slidably connected to the bottom plate 81.

[0039] A seventh fixed block 85 is fixedly connected to the bottom of the bottom plate 81, the seventh fixed block 85 is rotatably connected to the friction block 84 through a bearing, a third slider 82 is fixedly connected to the bottom of the bottom plate 81, and a roller 83 is rotatably connected to the side surface of the third slider 82.

[0040] An eighth fixed block 88 is fixedly connected to the top of the fixed bearing 86, and a spring 87 is slidably connected to the surface of the fixed bearing 86. A ninth fixed block 89 is fixedly connected to the middle side surface of the eighth fixed block 88, and a clamping slider 810 is rotatably connected to the surface of the ninth fixed block 89 through a bearing.

[0041] The height adjusting mechanism 6 includes a second support frame 66. A second support frame 66 is fixedly connected to the top of the center of the bottom plate 81. A first support frame 61 is slidably connected to the surface of the second support frame 66. A rotating lead screw 65 is threadedly connected inside the second support frame 66, and a second bevel gear 64 is fixedly connected to the top of the rotating lead screw 65.

[0042] The second support frame 66 is threadedly connected to the second bevel gear 64. The axis of the first bevel gear 63 is rotatably connected to a first motor 62 through a bearing.

[0043] The projection mechanism 5 includes a first fixed block 51. The first fixed block 51 is arranged on the top of the touch display screen 1. A second fixed block 52 is rotatably connected to the surface of the first fixed block 51. A third fixed block 53 is rotatably connected inside the second fixed block 52. A placement table 54 is rotatably connected to the back of the touch display screen 1.

[0044] During use, move the bottom plate 81 to an appropriate position. Then press the eighth fixing block 88 to move the fixed bearing 86 downward to compress the spring 87, so that the fixed bearing 86 presses the friction block 84 tightly to fix the roller 83 and prevent the roller 83 from sliding. Then rotate the clamping slider 810 to the bottom surface of the bottom plate 81, thereby restricting the spring 87 from releasing elastic force to bounce the eighth fixing block 88 upward. Then start the first motor 62, and its output bearing drives the first bevel gear 63 to rotate. The rotation of the first bevel gear 63 drives the second bevel gear 64 to rotate, and the rotation of the second bevel gear 64 drives the rotating lead screw 65 to rotate, so that the first support frame 61 drives the touch display screen 1 to move up or down, thereby adjusting the height of the touch display screen 1 to an appropriate position.

[0045] The roller 83 is set with a common color. For different course arrangements, the device can be quickly moved to different positions on the podium without laborious handling. At the same time, the friction block 84 is set. When the eighth fixing block 88 is pressed, the fixed bearing 86 presses the friction block 84 downward, thereby fixing the roller 83 and avoiding the problem of affecting students' attention due to the instability of the device, thus improving the quality and effect of teaching.

[0046] By setting the ninth fixing block 89 on the surface of the eighth fixing block 88, after pressing, the eighth fixing block 88 rotates the clamping slider 810 so that the clamping slider 810 contacts the bottom of the bottom plate 81, thereby further restricting the movement of the eighth fixing block 88, making the friction block 84 more firmly restrict the rotation of the roller 83, avoiding the problem of affecting students' attention due to the instability of the device, and further improving the quality and effect of teaching.

[0047] By setting a pen groove 2 on the side of the touch display screen 1, it is convenient for teachers or students to write directly on the touch display screen 1 through the pen in the pen groove 2 during teaching. And a placement table 54 is set. The teaching aids to be displayed are projected onto the touch display screen 1 by the projector fixedly connected to the bottom of the third fixing block 53. Their combination can effectively attract students' attention, improve the quality and effect of teaching. And a second support frame 66 is set. The rotation of the rotating lead screw 65 is driven by gear meshing transmission, so that the second support frame 66 moves up and down, thereby adjusting the height of the touch display screen 1 and avoiding the problem of affecting students' concentration due to inappropriate screen height, thus improving the quality and effect of teaching.

[0048] Embodiment 2: Please refer to Figures 1-8 , based on Embodiment 1, the present invention provides a technical solution:

[0050] The back of the touch display screen 1 is fixedly connected with a first support adjustment beam 71. The first support adjustment beam 71 is slidably connected with the second slider 75. The bottom of the touch display screen 1 is fixedly connected with a fifth fixing block 74. The back of the first support frame 61 is fixedly connected with a first motor 62.

[0051] During use, rotate the rotating adjustment block 76 to make the second slider 75 slide inside the first support adjustment beam 71, and make the other end of the first slider 72 rotate between the sixth fixing blocks 77, so that the touch display screen 1 rotates on the top of the first support frame 61, thereby adjusting the angle of the touch display screen 1.

[0052] By providing the rotating adjustment block 76, the sliding of the second slider 75 inside the first support adjustment beam 71 can be controlled by rotating the rotating adjustment block 76, so that the first slider 72 drives the touch display screen 1 to rotate on the top of the first support frame 61 through link transmission, thus avoiding the problem of affecting the students' concentration due to the screen not being perpendicular to the main line of sight direction of the students, and further improving the quality and effect of teaching.

[0053] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
