The teaching display board comprises a main display board, wherein a rectangular ink screen is inlaid in the front surface of the main display board, a wall hanging mechanism is arranged on the rear surface of the main display board, a storage mechanism is arranged at the bottom of the main display board, and a dustproof mechanism is arranged at the top of the main display board. According to the teaching display board, the storage mechanism is hidden at the bottom of the main display board, the operation is convenient, the storage function of the teaching tool is realized, and the uniformity of the whole structure of the main display board is not damaged; when the teaching display board is not used, sealing plates are pulled out of a groove in the top of the main display board, then the sealing plates are pulled to the bottom from the top along with wrapping cloth, and the wrapping cloth is used for effectively preventing dust for the ink screen; and the teaching display board is fixed on a wall through wall abutting rods, the distance between the main display board and a wall body is changed through movable deformation of spring rods, and therefore the flexibility of the teaching display board is enhanced.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a teaching exhibition board with a dustproof function. Background technique [0002] Teaching display boards, that is, the utensils used for writing demonstrations in the education industry.

Problems solved by technology

Whiteboards are usually used in conference rooms and multimedia teaching rooms. Although the practical teaching performance of the display boards is very good, due to the single form, most of the display boards use upright display boards. Due to the needs of supporting brackets, it is difficult to achieve different types of display boards. Due to the limitations of the wall hanging requirements, it is difficult to use the wall-mounted display boards in any occasion, and it cannot be used when there is no prerequisite for wall hanging; moreover, the display boards lack corresponding protection measures when they are idle , the dusty display board not only affects the use, but also reduces its service life
