When working, the writing board 7 is rotated, so that the writing board 7 drives the hinged rod 6 with it to rotate, so that the hinged rod 6 rotates on the connecting shaft 5 on the support frame 1, so that the writing board 7 is placed behind the support frame 1, which is convenient for the display 8 to perform multimedia teaching. When using the writing board 7, the writing board 7 is rotated to the front of the display 8 through the connecting shaft 5 and the hinge frame. When the writing board 7 is rotated to the front of the display 8, the sliding rod 93 is pulled upward, and the sliding rod 93 slides in the sliding groove 13, so that the clamping rod is aligned with the clamping groove 10, and then the sliding rod 93 is released. The spring connected to the sliding rod 93 uses its elastic force to make the clamping block 95 clamped in the clamping groove 10, thereby fixing the writing board 7, which is convenient for writing.

[0022] By rotating the writing board 7 and the connecting shaft 5, the user can easily switch between multimedia teaching and writing teaching. When the writing board 7 is not in use, it can be rotated behind the support frame 1 to save space while ensuring barrier-free use of the display 8. This makes space utilization in classrooms or conference rooms more efficient, especially in places where space is limited. The fixing component ensures the stability of the writing board 7 in a fixed position through the sliding rod 93, spring and snap block 95.

When installed, as above, it is convenient to repair and replace the display 8.

[0025] Example 3

[0026] like Figures 1 to 4 As shown, sliding grooves 13 are provided on both sides of the support frame 1, and the auxiliary teaching component includes a first servo motor 121, the first servo motor 121 is installed on the support frame 1, and a first gear 122 is installed on the first servo motor 121, and the first gear 122 is meshed with the second gear 123, and the second gear 123 is installed with a screw rod 124. Both ends of the screw rod 124 are rotatably connected to the support frame 1, and two driving blocks 126 are threadedly connected to the screw rod 124. An auxiliary teaching board 127 is installed on the driving block 126, and the top of the two auxiliary teaching boards 127 is slidably connected to the same slide rod 125, and the two ends of the slide rod 125 are fixed on the support frame 1. When working, the first servo motor 121 drives the first gear 122 to rotate, and the first gear 122 drives the second gear 123 meshed with it to rotate, and the second gear 123 drives the screw rod 124 connected thereto to rotate The screw rod 124 drives the two driving blocks 126 threadedly connected thereto to move to both sides, and then the driving blocks 126 drive the auxiliary teaching boards 127 connected thereto to move to both sides. At the same time, the tops of the auxiliary teaching boards 127 slide synchronously on the slide bars 125. Through the sliding grooves 13 on both sides of the support frame 1, the two auxiliary teaching boards 127 can be extended to both sides to display teaching materials. Driven by the first servo motor 121, the position and spacing of the auxiliary teaching boards 127 can be easily adjusted to meet the display requirements of teaching materials of different sizes and types. When display is not needed, the auxiliary teaching boards 127 can be retracted to both sides of the support frame 1 to save space. When display is needed, they can be unfolded to improve space utilization. The auxiliary teaching boards 127 can be flexibly arranged and replaced according to the teaching content, enriching the teaching content and helping to enhance students' learning interest and teaching effect.

[0027] Example 4

[0028] like Figures 1 to 5 As shown, the adjustment assembly includes a first support rod 141 and a second support rod 142, the first support rod 141 is slidably connected to the second support rod 142, and a fixing thread groove 143 is opened on both sides of the first support rod 141, and two connecting bolts 144 are installed on both sides of the second support rod 142, and the two connecting bolts 144 are threadedly connected to two of the fixing bolt 4 grooves on the first support rod 141. When working, the first support rod 141 is pulled, and the first support rod 141 slides on the second support rod 142, and then the fixing bolts 4 on both sides are threadedly connected to the fixing thread grooves 143 on the first support rod 141, thereby fixing the first support rod 141 and the second support rod 142, thereby adjusting the height of the support frame 1. The user can quickly change the height of the support frame 1 by simply pulling the first support rod 141 and adjusting its position on the second support rod 142 according to actual needs.

When working, the viewing angle can be adjusted by moving the universal wheel 17. At the same time, the universal wheel 17 can also facilitate the movement of the entire device, making it convenient for users to use.

[0030] Working principle: When working, the writing board 7 is rotated, so that the writing board 7 drives the hinged rod 6 connected thereto to rotate, so that the hinged rod 6 rotates on the connecting shaft 5 on the support frame 1, thereby placing the writing board 7 behind the support frame 1, which is convenient for display 8 to perform multimedia teaching. When using the writing board 7, the writing board 7 is rotated to the front of the display 8 through the connecting shaft 5 and the hinge frame. When the writing board 7 is rotated to the front of the display 8, the sliding rod 93 is pulled upward, and the sliding rod 93 slides in the sliding groove 13 so that the clamping rod is aligned with the clamping groove 10, and then the sliding rod 93 is released. The spring connected to the sliding rod 93 uses its elastic force to make the clamping block 95 snap into the clamping groove 10, thereby fixing the writing board 7, which is convenient for writing. Through the design of rotating the writing board 7 and the connecting shaft 5, the user can easily switch between multimedia teaching and writing teaching. When the writing board 7 is not in use, it can be rotated to the back of the support frame 1, thereby saving space while ensuring the barrier-free use of the display 8.
