Abstract
The utility model relates to an automatic rotation type dust-proof blackboard eraser, relating to the blackboard eraser for teaching and solving the technical problem that the dust-proof blackboard eraser can not erase the blackboard completely. The utility model is principally composed of a ring blackboard eraser, a cover body of the blackboard eraser, an upper orbit and a lower orbit, a driving wheel, a follower wheel and a motor. The upper orbit and the lower orbit with groove shapes are respectively fixed to the upper part and the lower part of the blackboard, and the ring blackboard eraser is arranged in the cover body of the blackboard eraser and tightened by the driving wheel and the follower wheel, and wherein, the driving wheel is driven by an electromotor. The upper end and the lower end of the cover body of the blackboard eraser are rolled and respectively matched with the upper orbit and the lower orbit and the cover body of the blackboard eraser is fastened with a dust-storing box. The automatic rotation type dust-proof blackboard eraser has the advantages of simple, convenient and practical structure and can effectively protect environmental sanitation, so the automatic rotation type dust-proof blackboard eraser is extensively used for teachings at schools.
Description
Affiliated technical field
The utility model relates to the blackboard eraser of the usefulness of imparting knowledge to students, the especially a kind of automatic rotary dust-proof blackboard eraser that can inhale the chalk dust end.
Background technology
Chalk mark on erasing the board with existing blackboard eraser, dust from flying, it is healthy to influence teachers and students.For addressing this problem,, be not widely used though have dust-proof blackboard eraser, electric dust absorption blackboard eraser to come out always.
The utility model content
At the deficiency that prior art exists, the utility model provides a kind of automatic rotary dust-proof blackboard eraser, and it erases the board effective, can walk automatically, and prevent dust from flying.
The technical scheme in the invention for solving the technical problem is: the automatic rotary dust-proof blackboard eraser mainly contains annular blackboard wiping, blackboard eraser cover body, upper and lower track, driving wheel, driven pulley and A motor and forms.Upper and lower track is the grooved hard material.The notch that gets on the right track is downward, and the lower railway notch makes progress, and crosswise fixed is at the blackboard upper and lower respectively, and lower railway and blackboard have certain distance.Ring-like blackboard eraser is arranged in the blackboard eraser cover body, palm fiber or felt that annular blackboard is wiped are fixed on the banded basis, annular blackboard is wiped by driving wheel and driven pulley tensioning, it is corresponding with the blackboard height that annular blackboard is wiped major diameter, drive sprocket axle passes the Cover of backboard eraser end face by the A Motor Drive, and driven pulley is fixed in the blackboard eraser cover body end face.The top and bottom that annular blackboard is wiped cover body respectively with get on the right track and lower railway rolls and cooperates.A bell mouth is established near the blackboard position in blackboard eraser cover body lower surface, and with the dust storage box snapping.
Described annular blackboard is wiped the uncovered periphery of cover body and is studded with elastic sealing strip.A lateral scrollwheel is established in blackboard eraser cover body upper end, and a vertical runner is established and by the B Motor Drive in its lower end.
Establish a dust catcher in the described bell mouth.
Described A, B motor are equipped with and turn to control.
The beneficial effects of the utility model are: owing to take technique scheme, blackboard eraser can also rotate when doing translational motion, erases the board not only soon but also clean.In addition, because dust catcher has been installed in the import of dust storage box, can make dust quicken.
Description of drawings
Fig. 1 is that automatic rotary dust-proof blackboard eraser master looks schematic diagram;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure, 1, get on the right track, 2, lower railway, 3, the blackboard eraser cover body, 4, annular blackboard wipes, 41, driving wheel, 42, the A motor, 43, driven pulley, 5, dust storage box, 6, lateral scrollwheel, 7, vertical runner, 71, the B motor, 8, blackboard, 9, bell mouth, 10, dust catcher.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
In Fig. 1 and Fig. 2, get on the right track 1 and lower railway 2 be the flute profile hard material.1 notch that gets on the right track is downward, and crosswise fixed is on blackboard 8; Lower railway 2 notches upwards, crosswise fixed and has certain distance with blackboard 8 below blackboard 8.Annular blackboard wipes 4 by driving wheel 41 and driven pulley 43 tensionings, and it is highly corresponding with blackboard 8 that annular blackboard is wiped 4 major diameters; 41 of driving wheels pass blackboard eraser cover body 3 end faces and are driven by A motor 42, and driven pulley 43 is fixed in blackboard eraser cover body 3 end faces.Blackboard eraser cover body 3 lower surfaces near blackboard 8 positions establish a bell mouth 9 and with dust storage box 5 snappings.Annular blackboard is wiped cover body 3 uncovered peripheries and is studded with elastic sealing strip, and a lateral scrollwheel 6 is established in blackboard eraser cover body 3 upper ends, and a vertical runner 7 is established and by the B Motor Drive in its lower end.Lateral scrollwheel 6 and vertical runner 7 roll with upper and lower track 1,2 respectively and cooperate.Establish a dust catcher 10 in the bell mouth 9.
