Abstract

The invention discloses a rolling type blackboard eraser assembly which comprises a holding part, a mounting rack, a screw, rolling wheels and two cleaning mechanisms. One end of the mounting rack is connected with the holding part. The screw is rotationally connected with the mounting rack. The rolling wheels are mounted on the screw. The two cleaning mechanisms are distributed on the two sides of the screw correspondingly. The cleaning mechanisms comprise first gears and wiping rag assemblies. The first gears are rotationally connected with the mounting rack and engaged with the screw. The wiping rag assemblies are mounted on the first gears.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a rolling blackboard eraser assembly. Background technique [0002] The blackboard eraser is a special tool used to wipe the blackboard. It can easily erase the chalk on the blackboard, so that the blackboard can be reused. The school is the place where the blackboard eraser is used the most. Other places such as corporate bulletin boards and some training institutions Waiting will also use the blackboard, and the place where the blackboard is used will always have the shadow of a blackboard eraser. [0003] At present, when cleaning the blackboard, people mainly use a blackboard eraser to erase the chalk on the blackboard. There is no way to clean up the characters on the height of the blackboard; the existing blackboard eraser needs to be improved. Contents of the invention [0004] In order to solve the technical problems in the background technology, the present in...
