Abstract

The invention discloses a reflection preventing blackboard. The reflection preventing blackboard comprises a frame, a first supporting rod, a second supporting rod, a third supporting rod, a first blackboard body, a second blackboard body, a third blackboard body and a driving mechanism, wherein the frame comprises a first border, a second border, a third border and a fourth border; the first border, the second border, the third border and the fourth border are arranged successively; the first border is opposite to the third border; the first border and the third border are arranged vertically; the second border is opposite to the fourth border and is placed above the fourth border; and the second border and the fourth border are arranged horizontally. The distance between the first blackboard body and a vertical plane and the distance between the third blackboard body and the vertical plane can be adjusted effectively, students at different positions can observe well, adaptability is good, influence caused by reflection is avoided, and therefore, teaching is facilitated.

Description

technical field [0001] The invention relates to the technical field of teaching supplies, in particular to a blackboard which avoids reflection. Background technique [0002] The blackboard is a tool that we must use in teaching, but the blackboard under the current technology has the following defects.
