Abstract

The invention discloses a blackboard comprising a framework and two blackboard sets. The framework comprises a first frame, a second frame, a third frame and a fourth frame which are sequentially arranged; the first frame and the third frame are oppositely arranged and both vertically arranged; the second frame and the fourth frame are oppositely arranged, the second frame is arranged above the fourth frame, and the second frame and the fourth frame are horizontally arranged; the two blackboard sets are distributed in the length direction of the second frame and each comprise a blackboard body, a supporting rod and a driving mechanism; the supporting rods are parallel to the first frame; the first end of each supporting rod is rotationally connected with the second frame; the second end of each supporting rod is rotationally connected with the fourth frame; the blackboard bodies are installed on the supporting rods; and the driving mechanisms are used for driving the blackboard bodies to rotate with the supporting rods as centers. According to the blackboard, the positions of the blackboard bodies can be effectively adjusted, and light reflecting interference is avoided.

Description

Technical field [0001] The invention relates to the technical field of teaching supplies, in particular to a blackboard.
