Problems solved by technology

[0003] Today's mathematics teachers need to write a lot on the blackboard during the teaching process. After writing on one side of the blackboard, they need to wipe it. Now the chalk dust will fly around during the wiping process, which affects the teacher's working environment and is not convenient for people to use. Therefore, it is urgently needed A kind of auxiliary device for mathematics teaching solves the above problems

Abstract

The invention discloses an auxiliary device for mathematics teaching. The device comprises a supporting column, a limiting groove is formed in the outer wall of one end of the supporting column, limiting blocks are slidably connected to the inner wall of the limiting groove, the same blackboard is arranged on the outer walls of one ends of the two limiting blocks, a mounting block is arranged at the top of the outer wall of one side of the blackboard, a rectangular groove is formed in the outer wall of the top of the mounting block, the inner walls of the two sides of the rectangular groove are rotationally connected with the same lead screw, and the circumferential outer wall of the lead screw is rotationally connected with a sliding block through a thread. According to the device, through the arrangement of a motor, the mounting block, the lead screw and an air inlet pipe below the sliding block, a placing block and a wiping block on the air inlet pipe can be driven to move back andforth on the surface of the blackboard, the surface of the blackboard can be wiped, and the wiping workload of a teacher is reduced; and through the arrangement of an air pump on a storage shell, dustgenerated when the blackboard is wiped by the wiping block can be adsorbed and collected through an air inlet hole in the air inlet pipe, and the working environment of a worker is improved.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to an auxiliary device for mathematics teaching. Background technique [0002] At this stage, the education industry is booming, and the state supports education vigorously. Parents also attach great importance to their children's education, and teaching aids have also emerged as the times require. Mathematics is a subject that studies concepts such as quantity, structure, change, space, and information. From a certain perspective, it is a kind of formal science. Mathematics plays an irreplaceable role and is also indispensable for learning and researching modern science and technology. The basic tool of learning mathematics will use mathematics auxiliary teaching device. [0003] Today's mathematics teachers need to write a lot on the blackboard during the teaching process. After writing on one side of the blackboard, they need to wipe it. Now the chalk dust will fly around ...
