[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0022] See also Figures 1 to 4 In the utility model, a teaching display board includes a bracket 1, a mounting frame 2 is rotatably mounted on the bracket 1, mounting grooves 3 are provided on both sides of the mounting frame 2, and display panels 4 are clamped inside the two mounting grooves 3, two clamping members 5 are installed on one side of the mounting frame 2, and the two clamping members 5 are respectively clamped and matched with the two display panels 4, and a positioning member 6 is installed on the bracket 1, and the positioning member 6 is connected and matched with the display panel 4.

[0023] In the utility model, the bracket 1 is used as the device support. When in use, the mounting frame 2 is first positioned and kept vertically by the positioning member 6 on one side, which is convenient for teaching and writing. When it is necessary to clean the display board 4 that is difficult to clean after long-term teaching and writing, the clamping member 5 is pulled horizontally, and then the display board 4 that needs to be cleaned is removed, and then the mounting frame 2 is rotated and turned 180 degrees, and then fixed by the positioning member 6, and the display board 4 on the other side of the mounting frame 2 is used to continue teaching, and the disassembled display board 4 is convenient for thorough cleaning, thereby achieving the advantages of being more convenient and flexible to use, easy to thoroughly clean, and extending the service life, and solving the problem that the general display board and the support frame in the prior art are connected in an indestructible manner. Although the display board can be wiped and written again, after long-term use, marks that are difficult to wipe will be produced on it, and due to the inconvenience of disassembly, it is difficult to thoroughly clean it, and the service life is reduced.

[0024] See also Figure 1 and Figure 2 , wherein: the clamping member 5 includes an I-beam clamp rod 51 and two springs 52, both ends of the I-beam clamp rod 51 are inserted into the mounting frame 2 and the ends extend into the interior of the mounting groove 3, the two ends of the I-beam clamp rod 51 are clamped with the expansion board 4, one end of the spring 52 is fixedly connected to the I-beam clamp rod 51, and the other end of the spring 52 is fixedly connected to the mounting frame 2.

[0025] In the utility model, two springs 52 generate a pulling force on the I-shaped clamp rod 51 to generate a force inside the installation groove 3 to clamp and position the side of the expansion plate 4, thereby realizing flexible disassembly and assembly of the expansion plate 4 and convenient operation.

[0026] See also Figure 1 and Figure 2 , wherein: the positioning member 6 includes a positioning block 61 and a threaded rod 62, the bottom bracket 1 of the positioning block 61 is fixedly connected, the outer side of the threaded rod 62 is threadedly connected to the positioning block 61, and the end of the threaded rod 62 is inserted into the mounting frame 2 and threadedly connected thereto.
