Abstract

The invention relates to a blackboard, in particular to an adjustable blackboard for teaching. The adjustable blackboard for teaching is capable of adjusting the height of the blackboard convenientlyto facilitate writing by a teacher and effectively cleans chalk dust. The adjustable blackboard for teaching comprises a mounting plate, an annular sliding rail, supporting sliding blocks, L-shaped supporting rods, a fixing plate, a motor and the like. The annular sliding rail is arranged at the top of the mounting plate, and the supporting sliding blocks are slidably connected into the annular sliding rail in a left and right symmetrical mode. The L-shaped supporting rods are arranged at the top ends of the supporting sliding blocks on the left and right sides, and a mounting frame is arranged at the top ends of the L-shaped supporting rods on the left and right sides. By adjusting the position of a second blackboard and a first blackboard, the adjustable blackboard for teaching providesthe teacher with a suitable writing height, the need for the teacher to bend too much when writing the teaching content is avoided, teaching tools such as chalks and blackboard erasers can be placed through a placing box, quick pick-up is facilitated for the teacher, and the effect of saving classroom time is achieved.
