Math teaching aid quick cleaning device for facilitating teaching

Abstract

The invention discloses a math teaching aid quick cleaning device for facilitating teaching in order to solve the problem that it is not convenient for an existing device to quickly clean math teaching aids with little effort. The math teaching aid quick cleaning device for facilitating teaching comprises a fixing frame, a first sliding rod, a second sliding rod, a screw rod, a fixing plate, a cleaning layer, a first connecting block, connecting rods, positioning plates, water tanks, arc strips and connecting pipes, wherein rotary shafts are installed between the water tank and the positioningplates, chains are installed between the rotary shafts, and the outer side of the rotary shaft at the right end of each positioning plate is fixedly connected with a motor. By arranging the motors, the water tanks are driven to rotate when the motors run, the surface of a math teaching aid is frictionally wetted while the water tanks rotate, and the math teaching aid slides into the fixing frame,so that more labor is saved; and through cooperation of third spiral springs and the connecting pipes, the uneven position of the math teaching aid can be better cleaned, and more convenience is provided.

Description

technical field [0001] The invention relates to the technical field of educational appliances, in particular to a quick-cleaning device for mathematics teaching appliances convenient for teaching. Background technique [0002] Teaching aids are used as teaching aids for teachers, especially when teaching geometry knowledge in mathematics courses, intuitive and standard graphics are required for demonstration, so that students can more easily accept them. However, most of the existing mathematics teaching aids are wooden rulers, triangles, Protractors, compasses, etc., when drawing graphics, the friction between the chalk and the teaching aids will drop a layer of chalk dust on the surface of the teaching aids, which will affect the teacher's viewing of the scale on the teaching aids, and will reduce the accuracy of drawing. When cleaning, it is generally wiped directly with a rag. However, the user needs to prepare multiple rags separately. After wiping the wet rag, in order...
