Description
Technical field
This utility model relates to blackboard eraser technical field, more particularly, it relates to a kind of multiaspect recycling blackboard eraser.
Background technology
Blackboard eraser is that school is essential and use one of the teaching aid of very high frequency.At present, the blackboard eraser that school is conventional is main
Having two kinds, one is snag type blackboard eraser, and another kind is wiper type blackboard eraser.It is typically all and uses snag or wiper (to call wiping in the following text
Body) embed in blackboard eraser casing (calling wiping case in the following text), rub back and forth between rub body and blackboard to wipe powder under certain pressure effect
Dirt.
Owing to blackboard eraser uses frequency the highest, it is easy to cause rub body damaged, after special blackboard eraser was used several times, the corner of rub body
Or edge digs, and causing blackboard eraser ineffective, the newest blackboard eraser uses one will change for twice.Especially at plum rains
Season or the big place of dampness, the easy laying dust of rub body, in order to keep the wiping effect of blackboard eraser, teacher or student are accustomed to blackboard
Wiping carries out beaing dedusting, which increase rub body emerge wipe case probability, also shorten the service life of blackboard eraser.
Above reason objective reality, blackboard eraser replacement frequency is the highest, causes the biggest waste, is unfavorable for working hard and practising economy and environmental protection
Theory.Through retrieval, current domestic existing a lot of blackboard eraser Patents obtains and authorizes or product release, but is all more or less in
Certain defect or deficiency is there is in design.Such as Chinese Patent Application No. 200620046021.8, filing date in JIUYUE, 2006
19, invention and created name was: blackboard eraser；This application case includes box body and wiper, also a rotating shaft and square cylinder, turns
The two ends of axle are rotatably supported on the sidewall of box body, and square cylinder is positioned at box body and is fixed in rotating shaft, described wiper bag
Being rolled in the surface of square cylinder, box body is provided with the lid that can overturn.The blackboard eraser of this application case is due to four of square cylinder
It is designed with wiper on face, after a face is stained with chalk dust, opens the lid, rotate cylinder and can change work surface, decrease powder
The chance that pen ash is unrestrained.But the wiper of this application case can not pull down cleaning from square cylinder, wanting of life-time service still can not be met
Ask, be unfavorable for working hard and practising economy and environmental protection concept.
China Patent No. ZL 201220640989.9, authorized announcement date is on June 9th, 2013, and invention and created name is: three
Dark complexion blackboard eraser；The triangular prism flap of this application case includes rotating shaft and the triangular prism drapery panel face being sleeved in rotating shaft, described Rhizoma Sparganii
Post flap is fixed on inside box between upper and lower cylindrical hole by rotating shaft, and outside box, three angle knobs are installed in rotating shaft one end.Institute
The one end stating rotating shaft engages each other equipped with gear, the gear that adjacent two rotating shafts are installed.It is carved with mark line outside described box.
At least one triangular prism flap it is provided with in described box.This application case overcomes existing blackboard eraser can only use one side, easily because
The chalk dust of its surface accumulation is too much, and the shortcoming that cannot clean off a blackboard, three dark complexion blackboard erasers achieve the conversion between three,
Another side, the trouble that when can avoid erasing the board, dust is existed everywhere is changed when one dust is too much.But this application case structure is complicated, system
Cause high, and operation inconvenience, still need to improve further.
