Abstract
This utility model provides a teaching display board, relating to the field of teaching aids, comprising: an adjustable base, a mounting frame fixedly connected to the adjustable base, a teaching display whiteboard fixedly connected to the inner wall of the mounting frame, two mounting slides slidably disposed on both sides of the mounting frame, a strip whiteboard eraser disposed on the inner wall of the mounting slide, the side of the strip whiteboard eraser away from the mounting slide contacting the side wall of the teaching display whiteboard, and multiple limiting rods, both ends of which are fixedly connected to the inner wall of the mounting frame. With this design, after the teacher has finished teaching or completed a stage of teaching content, the mounting slides can be manually adjusted to move, and the movement of the mounting slides controls the movement of the strip whiteboard eraser to erase the interior of the teaching display whiteboard. Furthermore, the strip whiteboard eraser can cover the entire longitudinal position of the teaching display whiteboard during movement, thereby improving the efficiency of erasing text and images on the teaching display whiteboard.
