Teaching device for junior high school

Abstract

The invention discloses a teaching device for a junior high school. The teaching device comprises a blackboard main body, wherein the blackboard main body is fixedly installed on the wall of a classroom platform, and sliding tracks are fixedly installed on the walls of the upper and lower sides of the blackboard main body in the length direction of the blackboard main body. A cleaning device is movably arranged between the two sliding tracks, the cleaning device comprises two sliding blocks, the two sliding blocks are movably arranged on the sliding tracks, and a support plate is fixedly connected between the two sliding blocks. A handle is arranged in the middle part of one side of the support plate far away from the blackboard main body, and the support plate on the lower side is provided with a placing box. A short plate eraser is placed in the placing box, and telescopic support rods are arranged on one side of the support plate away from the handle at equal distances in the lengthdirection. The teaching device for the junior high school is novel in design, simple in structure, convenient to use and capable of efficiently wiping the blackboard, and the wiping effect is significant, at the same time, chalk dust can be collected to reduce dust in a classroom.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a teaching equipment for junior high schools.

Problems solved by technology

[0003] In junior high school teaching, due to the large number of subjects, each subject requires a large number of blackboard writing on the blackboard to enable more efficient teaching. However, when a large number of blackboard writing is cleaned by a blackboard eraser, the efficiency is low and it is easy to remain. A lot of dust is on the blackboard, and it is difficult to wipe the writing on the blackboard on the top of the blackboard, which leads to a lot of time spent cleaning the blackboard and a waste of classroom teaching time. Therefore, we have designed a teaching equipment for junior high schools to solve the above problems
