High-efficiency teaching tool for classroom management

Abstract

The invention relates to the field of teaching, in particular to a high-efficiency teaching tool for classroom management. The high-efficiency teaching tool for classroom management comprises a conveying mechanism, two side frames and two blackboard writing units, and each side frame is provided with a vertical groove and a transverse groove; the conveying mechanism comprises two conveying units; each conveying unit comprises a belt and a plurality of driven conveying parts, and each driven conveying part comprises a rotating shaft and a gear; each blackboard writing unit comprises a board body, an erasing part and two driving conveying parts; each driving conveying part comprises a plurality of double-sided racks, and the double-sided racks are fixedly connected with the side wall of the corresponding board body; sliding blocks are fixed to the double-sided racks; notches are formed between the adjacent double-sided racks; when the notches are aligned with the gears, the sliding blocks can slide into the transverse grooves from the vertical grooves; and each erasing part comprises a plurality of erasing blocks, the erasing blocks are connected with the back surface of the corresponding board body, and the erasing blocks can be in contact with the corresponding rotating shafts and the other board body. When the technical scheme is adopted, the classroom efficiency can be improved easily, and a blackboard can be wiped cleanly.

Description

technical field [0001] The invention relates to the field of teaching, in particular to a high-efficiency teaching tool for classroom management. Background technique [0002] In the process of classroom teaching, blackboards are often used for blackboard writing. Traditional blackboards are mostly composed of a blackboard. In the actual teaching process, the area of ​​a blackboard is usually not enough for the teacher to write on. During the teaching process, the blackboard needs to be erased many times. Continue teaching after the chalk characters, which is not conducive to meeting the high-efficiency teaching requirements. [0003] In order to solve the problem of improving teaching efficiency, the more popular blackboards on the market are usually composed of two pieces. The upper ends of the two blackboards are connected by wire ropes, and the positions of the two blackboards can be freely switched in the vertical direction to reduce the teacher’s erasure. The frequenc...

Problems solved by technology

[0004] However, for the situation where there are many blackboard writings, it still takes time to erase the entire blackboard after switching the blackboard, which will still affect the teaching efficiency. In addition, in order to speed up the erasing of the blackboard, the teacher usually does not erase the writing on the blackboard completely. It will affect the quality of blackboard writing, and will also reduce students' perception of blackboard writing
