Description
Technical field
The utility model relates to a kind of blackboard eraser dust arrester, belongs to teaching aid, is used for the removing of blackboard eraser chalk dust.
Background technology
In the teaching, no matter be that the teacher levies or the student is when erasing the board break, though used dust-free chalk, chalk dust still accumulates on the matte of blackboard eraser, under the normal condition all be with blackboard eraser at the dais, the blackboard lower frame or strike on the ground several down, to remove chalk dust.Do the chalk dust of still can kicking up like this, influence teacher and front-seat student's physical and mental health.
Summary of the invention
For effectively solving the chalk dust after blackboard eraser uses, the invention provides a kind of blackboard eraser dust arrester, be positioned on the closed dust arrester by the blackboard eraser after will using, manually Rotary dust collecting changes brush, chalk dust on the blackboard eraser is removed, and remove chalk dust down and in the dust arrester of enclosed, can reclaim, thereby play the physical and mental health effect of protecting environment and teachers and students; The appearance surfaces of dust arrester is designed to casper or pastes curriculum schedule seating plan, the effect of accomplishing one-object-many-purposes.
The technical solution of the utility model is: a kind of blackboard eraser dust arrester comprises cover plate, box body, hairbrush, rotating cylinder, bolster, joint bolt, dust scraping plate, trim, spiral cover, left end cap, right end cap, crank.Described hairbrush embeds rotating cylinder periphery and uniform along rotating drum shaft five equilibrium on distribution in a row, circumference, cooperates rotating cylinder to be fixed on the bolster by interior external tooth, and bolster is installed on the end cap of the left and right sides and passes right end cap and crank fixes.Left and right sides end cap is in aggregates by screw attachment and box body, has blind hole and be used for fixing dust scraping plate on the end cap of the left and right sides.Box body is made top semicircle, bottom square box network structure, has the arc space with the blackboard eraser consistent size in the middle of just go up, and blackboard eraser is put in upset or take off cover plate during use.Box body below screw is used to pour out chalk dust, seals with spiral cover during the blackboard eraser dedusting.Outer surface at box body is pasted decorative panel.
When manufacturing, left and right sides end cap and box body are assembled into an integral body, and spiral cover is fixed on the box body, and dust scraping plate is fixed on the end cap of the left and right sides.The rotating cylinder that is embedded with hairbrush is installed in bolster and places the rotary hole of left and right sides end cap, fixing crank in the rotating shaft.The arc that on the other hand blackboard eraser is positioned over box body during use supports on the square hole and edge support circular swing motion, the another hand rotates crank, hairbrush on the rotating cylinder just brushes away the chalk dust on the blackboard eraser, and hairbrush is removed the chalk dust on the hairbrush during through the dust scraping plate of bottom in rotating, chalk dust finally falls into the bottom precipitation of box body, and the chalk dust of accumulation can be poured out when screwing off spiral cover.
Box body appearance trim pattern in the blackboard eraser dust arrester described in the utility model can fashion into casper or paste curriculum schedule seating plan, the effect of accomplishing one-object-many-purposes and decorative environment.
