Abstract

The invention discloses a movable blackboard for English teaching. The movable blackboard comprises a supporting frame, a plate body, a left column and a right column; the supporting frame is of a slot-shaped mechanism with an opening at the top, and the plate body is disposed in the supporting frame; straight tooth surfaces are symmetrically disposed on the left and right side faces of the platebody, and a driving gear is rotatably connected to the right side of the front end surface of the supporting frame; a limit gear is rotatably connected with the left side of the front end surface of the supporting frame, and the limit gear meshes with the left straight tooth surface of the plate body; and a locking mechanism is disposed below the limit gear, and the left column and the right column are fixed to the bottom of the supporting frame. The movable blackboard has clever structure and reasonable design and can adjust the height of the plate body according to the height of a teacher, and the height adjustment operation is simple and quick; and at the same time, the movable blackboard can quickly switch between the static placing state and the moving state and achieves the effect ofsaving time and labor, the stability in the static placing state is high, and the development of English teaching work is facilitated.
