Abstract
The invention discloses a dust blocking board for a blackboard, and relates to the technical field of blackboard dust blocking. The dust blocking board is provided with a bottom board, wherein a guide groove penetrating through the bottom board is formed along the transverse direction of the bottom board, a slide block sliding along the guide groove is arranged on the guide groove, a sweeping device is arranged on the slide block, a dust leaking groove is formed in the tail end of the bottom board, and a dust storage box is movably arranged at the back side of the bottom board corresponding to the dust leaking groove. The dust blocking board for the blackboard has the advantages that the structure is simple, the dust blocking board is used for containing falling chalk dust, and the pollution is reduced.
Description
Technical field
The present invention relates to blackboard gear gray technology field, specifically a kind of blackboard dust block board.
Background technology
Blackboard for education not specially gives advice black writing plate, traditional sense is said be it one can the surface plate of repeated writing, plate face is hard, not reflective, for teaching.Mainly green plate and blank occupy staple market as things go, are secondly cream-coloured plates.Chalk-writing (also can use liquid aqueous chalk-writing) mainly used by green plate; Blank mainly uses white board marker to write, and cream-coloured plate mainly uses free ink pen to write.
Blackboard for education plate face generally adopts magnetic color coated steel sheet to make, and plate face thickness is many between 0.2mm-0.4mm, this kind of material have wear-resisting, do not come off, colour-fast, durable in use, write good hand touch, the features such as writing is clear, easy-to-write and erasable.
And existing blackboard for education is main or green plate is main, and this kind of blackboard is when adopting chalk-writing, and chalk dust, when falling, owing to not having ash retention equipment, is trickled down everywhere, contaminated environment.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides a kind of blackboard dust block board, for placing the chalk dust of whereabouts.
The present invention realizes with following technical scheme: a kind of blackboard dust block board, bag expansion one base plate, and the transverse direction along base plate is provided with the gathering sill running through base plate, gathering sill is installed a slide block slided along gathering sill, slide block is provided with clearing apparatus; Be provided with leakage ash-pit at the tail end of base plate, the back side of the base plate corresponding with leaking ash-pit is movably installed with stored ash box.
Advantage of the present invention is: structure is simple, for placing the chalk dust of whereabouts, decreasing pollution.
