The lifting assembly 2 includes a storage rod 23, which is fixedly installed on the top surface of the base plate 1. A first motor 21 is fixedly installed inside the storage rod 23. A threaded rod 22 is fixedly connected to the output end of the first motor 21. An extension rod 24 is threadedly connected to the surface of the threaded rod 22. A turntable 26 is rotatably installed on the top of the extension rod 24. A fixing assembly 25 is fixedly connected to one side surface of the mounting bracket 4.

[0017] By adopting the above technical solution, when using the lifting component 2, if it is necessary to adjust the height of the whiteboard body 5, the first motor 21 is started. The first motor 21 drives the threaded rod 22 to rotate inside the storage rod 23. The threaded rod 22 further pushes the extension rod 24 to move upward, thereby adjusting the whiteboard body 5 to a suitable height. When it is necessary to adjust the orientation angle of the whiteboard body 5, the position of the whiteboard body 5 can be adjusted and locked by the turntable 26 cooperating with the fixing component 25.

[0018] Specifically, the fixing component 25 includes a connecting plate 255, which is fixedly installed on the middle of one side surface of the mounting bracket 4. A fixing bracket 252 is fixedly connected to the top surface of the connecting plate 255. A fixing screw 251 is rotatably provided on the inner side of the fixing bracket 252. A movable plate 253 is rotatably provided at the bottom of the fixing screw 251. A pin 254 is fixedly connected to the bottom surface of the movable plate 253.

[0019] By adopting the above technical solution, when adjusting the orientation angle of the whiteboard body 5, the fixing screw 251 is first rotated by the handwheel. The fixing screw 251 further pushes the movable plate 253 and the pin 254 upward until the pin 254 disengages from the insertion hole on the top surface of the turntable 26. At this time, the pin 254 is no longer limited by the mounting bracket 4. The whiteboard body 5 can be rotated to adjust the angle through the turntable 26. After adjusting to the appropriate position, the pin 254 is aligned with the insertion hole, and the fixing screw 251 is rotated so that the fixing screw 251 pushes the pin 254 into the insertion hole, thus completing the orientation adjustment and locking of the whiteboard body 5.

[0020] Specifically, the top surface of the turntable 26 has an insertion hole, and a rotating shaft is installed between the turntable 26 and the mounting bracket 4.

[0021] By adopting the above technical solution, the direction of the whiteboard body 5 can be adjusted more flexibly by using the pin 254 in conjunction with the sockets at different positions, and the turntable 26 can drive the whiteboard body 5 to rotate via the rotating shaft.

[0022] Specifically, guide blocks are fixed to both ends of the movable plate 253, and guide grooves are provided on the inner surface of the fixed frame 252.

[0023] By adopting the above technical solution, the stability of the movable plate 253 can be improved by the guide block moving inside the guide groove during movement.

[0024] Specifically, a through hole is provided on the inner side of the connecting plate 255, and a handwheel is fixed to the top of the fixing screw 251.

[0025] By adopting the above technical solution, the through hole facilitates the insertion of the pin 254 through the connecting plate 255 into the socket, and the handwheel facilitates the operation of the fixing screw 251 by the staff, thus simplifying the operation process.

[0026] In this embodiment, when using the lifting assembly 2, if the height of the whiteboard body 5 needs to be adjusted, the first motor 21 is started. The first motor 21 drives the threaded rod 22 to rotate inside the storage rod 23. The threaded rod 22 further pushes the extension rod 24 upward, thereby adjusting the whiteboard body 5 to a suitable height. When the orientation angle of the whiteboard body 5 needs to be adjusted, the position of the whiteboard body 5 can be adjusted and locked by the turntable 26 cooperating with the fixing assembly 25. When adjusting the orientation angle of the whiteboard body 5, the fixing screw 251 is first rotated by the handwheel. The fixing screw 251 further pushes the movable plate 253 and the pin 254 upward until the pin 254 disengages from the insertion hole on the top surface of the turntable 26. At this time, the pin 254 is released from the pin. The mounting bracket 4 is limited, and the whiteboard body 5 can be rotated and its angle adjusted by the turntable 26. After adjusting to the appropriate position, the pin 254 is aligned with the socket, and the fixing screw 251 is rotated to push the pin 254 into the socket, thus completing the direction adjustment and locking of the whiteboard body 5. By cooperating with the sockets at different positions, the direction of the whiteboard body 5 can be adjusted more flexibly. The turntable 26 can be driven by the rotating shaft to rotate the whiteboard body 5. When the movable plate 253 moves, it moves in the guide groove through the guide block, which can improve the stability of the movable plate 253. The through hole makes it easy for the pin 254 to pass through the connecting plate 255 and be inserted into the socket. The handwheel makes it easy for the staff to operate the fixing screw 251, simplifying the operation process. Example

[0027] The difference between this embodiment and embodiment 1 is that, specifically, the telescopic component 3 includes a top seat 31, which is fixedly mounted on the top surface of the whiteboard body 5. A bidirectional screw 32 is rotatably mounted on the inner side of the top seat 31. A second motor 33 is fixedly connected to one end of the bidirectional screw 32. A threaded block 36 is threadedly connected to the surface of the bidirectional screw 32. An installation block 35 is fixedly connected to the bottom of the threaded block 36. A movable whiteboard 34 is fixedly mounted on the bottom of the installation block 35.

[0028] By adopting the above technical solution, when using the telescopic component 3, if it is necessary to compare the content displayed on the movable whiteboard 34, the second motor 33 is started. The second motor 33 drives the bidirectional screw 32 to rotate, and further drives the movable whiteboards 34 on both sides to move to both sides through the threaded block 36 and the mounting block 35 until the whiteboard body 5 is fully extended. At this time, different teaching content can be displayed on the whiteboard body 5 for students to compare and learn, which helps to enhance the teaching effect. After use, the second motor 33 reverses, which can reset the movable whiteboard 34 and avoid occupying too much space.

[0029] Specifically, the bottom of the mounting block 35 has a mounting groove, and a fixing bolt is installed on one side of the mounting groove.

[0030] By adopting the above technical solution, different mobile whiteboards 34 can be easily installed and fixed using mounting slots and fixing bolts, and the mobile whiteboards 34 can also be easily inspected and maintained.

[0031] In this embodiment, when using the telescopic component 3, if it is necessary to compare the content displayed on the movable whiteboard 34, the second motor 33 is activated. The second motor 33 drives the bidirectional screw 32 to rotate, which further drives the movable whiteboards 34 on both sides to move to both sides through the threaded block 36 and the mounting block 35 until the whiteboard body 5 is fully extended. At this time, different teaching content can be displayed on the whiteboard body 5 for students to compare and learn, which helps to enhance the teaching effect. After use, the second motor 33 reverses to reset the movable whiteboard 34, avoiding occupying too much space. The mounting slot and fixing bolts facilitate the installation and fixing of different movable whiteboards 34, and also facilitate the maintenance of the movable whiteboard 34.

[0032] The working principle and usage process of this utility model are as follows: When using the lifting component 2, if the height of the whiteboard body 5 needs to be adjusted, the first motor 21 is started. The first motor 21 drives the threaded rod 22 to rotate inside the storage rod 23. The threaded rod 22 further pushes the extension rod 24 upward, thereby adjusting the whiteboard body 5 to a suitable height. When the orientation angle of the whiteboard body 5 needs to be adjusted, the position of the whiteboard body 5 can be adjusted and locked by the turntable 26 cooperating with the fixing component 25. When adjusting the orientation angle of the whiteboard body 5, the fixing screw 251 is first rotated by the handwheel. The fixing screw 251 further pushes the movable plate 253 and the pin 254 upward until the pin 254 disengages from the insertion hole on the top surface of the turntable 26. At this time, the pin 254... The limit on the mounting bracket 4 is removed. The whiteboard body 5 can be rotated and its angle adjusted by the turntable 26. After adjusting to the appropriate position, the pin 254 is aligned with the socket. The fixing screw 251 is rotated so that the fixing screw 251 pushes the pin 254 into the socket. This completes the direction adjustment and locking of the whiteboard body 5. By cooperating with the sockets at different positions, the direction of the whiteboard body 5 can be adjusted more flexibly. The turntable 26 can be driven by the rotating shaft to rotate the whiteboard body 5. When the movable plate 253 moves, it moves in the guide groove through the guide block, which can improve the stability of the movable plate 253. The through hole makes it easy for the pin 254 to pass through the connecting plate 255 and be inserted into the socket. The handwheel makes it easy for the staff to operate the fixing screw 251, simplifying the operation process. When using the telescopic component 3, if it is necessary to compare the content displayed on the movable whiteboard 34, the second motor 33 is started. The second motor 33 drives the bidirectional screw 32 to rotate, which in turn drives the movable whiteboards 34 on both sides to move to both sides through the threaded block 36 and the mounting block 35 until the whiteboard body 5 is fully extended. At this time, different teaching content can be displayed on the whiteboard body 5 for students to compare and learn from, which helps to enhance the teaching effect. After use, the second motor 33 reverses to reset the movable whiteboard 34, avoiding taking up too much space. The mounting slot and fixing bolts make it easy to install and fix different movable whiteboards 34, and also facilitate the maintenance of the movable whiteboard 34.
