[0005] Preferably, a plurality of blocks are evenly and fixedly provided on the vertical rod, the outer diameter of the blocks is larger than the diameter of the vertical rod, one end of the blocks is fixedly connected to the back of the display screen to ensure the stability of the position of the display screen, a plurality of rotating blocks are fixedly provided on one end of the writing board, the length between the blocks is larger than the length of the rotating block, axial holes are provided through the plurality of rotating blocks, and the vertical rod passes through the axial holes, which not only ensures a reliable connection between the writing board and the vertical rod, but also enables the writing board to rotate smoothly along the vertical rod.

[0006] Preferably, a groove is provided at the upper end of the support plate on the front side of the display screen to place writing pens and blackboard erasers for easy use.

[0007] Preferably, the sum of the lengths of the two writing boards is less than the length of the display screen, ensuring that the two writing boards can be closed on the back of the display screen, and the overall appearance is beautiful.

[0008] The beneficial effects of the utility model are as follows: the structural design of the utility model is relatively novel, the lower ends of the vertical rods on both sides of the back of the display screen are fixedly connected to the support plate, one end of the writing board is hingedly connected to the vertical rods, the writing board rotates within a certain range along the vertical rods, and a baffle is vertically arranged in the limiting hole on the support plate. The position of the writing board is blocked by the baffle to ensure the stability and reliability of the position of the writing board, so that the writing board can be flipped to the writing position at any time when blackboard writing is needed. The operation is convenient and quick, which improves the quality of teaching. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to more clearly understand the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-5An interactive teaching aid shown in the figure includes a bracket 1, a support plate 2 is horizontally fixedly arranged on the upper end of the bracket 1 to reliably support a display screen 3, a display screen 3 is vertically arranged in the middle position on the support plate 2 for PPT or video presentation, vertical rods 4 are vertically symmetrically arranged at the outer edges of both sides of the back of the display screen 3, and the lower ends of the vertical rods 4 are fixedly connected to the support plate 2 to ensure the reliable position of a writing board 5, and writing boards 5 are vertically symmetrically arranged on the support plate 2 on the back of the display screen 3 for writing, and the sum of the lengths of the two writing boards 5 is less than the length of the display screen 3, ensuring that the two writing boards 5 can be closed on the back of the display screen 3, and the overall appearance is beautiful. One end of the writing board 5 is hingedly connected to the vertical rod 4, and the writing board 5 rotates within a certain range along the vertical rod 4. Three blocks 9 are evenly and fixedly arranged on the vertical rod 4. The outer diameter of the block 9 is larger than the diameter of the vertical rod 4. One end of the block 9 is fixedly connected to the back of the display screen 3 to ensure the stability of the position of the display screen 3. Two rotating blocks 10 are fixedly arranged at one end of the writing board 5. The length between the blocks 9 is larger than the length of the rotating blocks 10. An axial hole 11 is opened through the two rotating blocks 10. The vertical rod 4 passes through the axial hole 11, which not only ensures the reliable connection between the writing board 5 and the vertical rod 4, but also enables the writing board 5 to rotate smoothly along the vertical rod 4. Four limiting holes 6 are provided on the support plate 2 located at the back of the display screen 3, and an insertion rod 7 is vertically arranged in the limiting hole 6. A blocking rod 8 is vertically fixed on the upper end of the insertion rod 7, and the position of the writing board 5 is blocked by the blocking rod 8 to ensure the stability and reliability of the position of the writing board 5. The diameter of the insertion rod 7 is the same as the aperture of the limiting hole 6 and is smaller than the diameter of the blocking rod 8, thereby ensuring the reliable connection between the insertion rod 7 and the support plate 2, preventing the insertion rod 7 from deflecting, and ensuring that the blocking rod 8 stands stably on the support plate 2.

[0017] A groove 12 is provided at the upper end of the support plate 2 located in front of the display screen 3 to place writing pens and blackboard erasers for easy use.

[0018] When the writing board 5 is not in use, the writing board 5 is flipped over to be close to the back of the display screen 3, and the insertion rod 7 is inserted into the limiting hole 6 located in the middle of the support plate 2 to limit the position of the writing board 5. When the writing board 5 is in use, the insertion rod 7 is removed, the writing board 5 is flipped 180°, and the insertion rod 7 is inserted into the limiting hole 6 located at the edge of the support plate 2 to limit the position of the writing board 5.

[0019] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
