Problems solved by technology

[0002] The blackboard is a tool that we must use in teaching, but the blackboard under the current technology has the following defects. For example, due to the large number of students in the classroom, when the students sitting on the edge observe the blackboard, the observation is not clear due to the reflection, which makes teaching inconvenient. It also affects learning and needs further improvement

Abstract

The invention discloses a blackboard assembly convenient for angle adjustment. The blackboard assembly convenient for angle adjustment comprises a frame, a support shaft, a blackboard body and an adjustment mechanism, wherein the frame comprises a first border, a second border, a third border and a fourth border which are sequentially arranged, and the first border and the third border are oppositely arranged, and are both vertically arranged; the second border and the fourth border are oppositely arranged, the second border is arranged above the fourth border, and the second border and the fourth border are both horizontally arranged; the support shaft and the first border are arranged in parallel, the first end of the support shaft is rotationally connected with the second border, and the second end of the support shaft is rotationally connected with the fourth border; the blackboard body is arranged at the inner side of the frame, a length direction of the blackboard body is parallel to a length direction of the second border, and the blackboard body is rotationally connected with the support shaft; and the adjustment mechanism is used for driving the blackboard body to rotate by taking the support shaft as a centre. The blackboard assembly convenient for angle adjustment, which is disclosed by the invention, avoids light-reflecting interference, and improves a teaching effect.

Description

technical field [0001] The invention relates to the technical field of teaching supplies, in particular to a blackboard assembly which is convenient for angle adjustment. 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.
