Description
Technical field
The present invention relates to a kind of blackboard of the usefulness of imparting knowledge to students, relate generally to a kind of multifunctional electric magnetic blackboard.
Background technology
Blackboard is the necessity of teaching usefulness, and the blackboard of existing teaching usefulness is that a ganoid stiff materials is made, normal coating black or blackish green.The blackboard panel of teaching usefulness adopts the high duty alloy steel plate that is coated with wear-resistant coating, and is wear-resisting, do not come off, colour-fast, durable in use.Write good hand touch, writing is clear, easily writes, and also easily wipes examination.The plate face is brushed into blackish green, does not stimulate people's eyes.Because blackboard is reflective, the student who is sitting in diverse location sees that the content of blackboard also has difference, is unfavorable for student's study.So occurred the figure of Arc shape blackboard on the market.Arc shape blackboard is constituted by the some fritter blackboards that are convexly curved in the horizontal, has alleviated the reverberation of student when the opposite side that looks at the blackboard that is positioned at front-seat side seat, makes them can not reflect the content of can't see on the blackboard because of light.Recessed in the middle of this blackboard has, two is gradually outstanding, the science visual angle; Large-scale luxurious frame has more three-dimensional grand.But, all to use this writing implement of chalk no matter be what blackboard.And the thin ash that chalk produces is but given people's the health hidden danger that works the mischief.China Patent No. is that a kind of plate face of 200610047440.8 can move up and down, and turns over the blackboard that circles and can clean automatically.Its driving member is contained on the rectangle combination sideboard framework, and the framework top is the power roll shaft that an end is connected with motor.The servo-actuated roll shaft of below guiding levelling tension is to be contained in scrubbing in the groove of below of framework.Scrubbing has the twice hairbrush in the groove, cleaning fluid is housed, and projection cloth telescopic chute and framework are to use the adjusting leading screw and the slideway on the tank bracket at projection cloth telescopic chute two ends to assemble.Its plate face is with the end to end collar shape of making of pitted skin black cloth insertion sheet.Metal liner backing plate of inboard peace of being close to up and down the front side board face in the plate face collar between two roll shafts, the other end of power roll shaft also is equipped with manual rope sheave and can guarantees not use as usual when having electricity or having a power failure up.This driven blackboard can make the teacher no longer stand a tiptoe or bend over and write, and can make the classmate who is sitting in each corner in the classroom can both see plate face content clearly, has also thoroughly eliminated the harm of dust to teachers and students' health.But when running into special teaching, in the time of need using projection cloth, also to seek projection cloth separately, with the time all to reinstall, use to show slightly trouble, make troubles to teaching.
Summary of the invention
The present invention is intended at prior art, and a kind of multifunctional electric magnetic blackboard that is fit to special teaching use and environmentally-friendly sanitary is provided.Adopt the present invention to give to write and offer convenience, and no dust pollution, make teaching more easy and convenient.
In order to realize the foregoing invention purpose, the technical solution used in the present invention is:
Multifunctional electric magnetic blackboard, comprise the plate face, it is characterized in that: described plate face is magnetic plate face, described plate face top is provided with the projection cloth box that projection cloth is housed, be provided with in the described projection cloth box for the flexible projection cloth telescopic chute of projection cloth, described projection cloth bottom is provided with clamp, plate face below is provided with the buckle with the clamp coupling, the bottom is provided with power switch and the switch that sprays water with high pressure, described plate face both sides are provided with bearing and turning cylinder, described turning cylinder one side is provided with special pens and wipes, and described plate face edge one side is provided with impact switch; Described plate face is a gear driven, and bottom margin one side is provided with the little metal aperture with the gear coupling, and the plate face rotates by the DC motor drives that is arranged on the bottom; Described projection cloth cooperates by projection cloth rolling bearing and projection cloth turning cylinder finishes rotation.
Described projection cloth rolling bearing one end is connected with wind.
Described projection cloth box below is provided with the water tank of bringing the mouth of a river into, and water tank one side is provided with the head that sprays water with high pressure.
Described plate face edge is provided with the magnetic glass of parcel plate face.
During use, in special teaching with projection cloth in the projection cloth box toward drop-down, move the snapped-in position of plate face below to, on the clamp card, not the time spent, promptly available wind takes in projection cloth in the projection cloth box.After writing full word on the plate face, press power switch, the plate face just rotates under the drive of gear, when the plate face turned to another side, the impact switch that is arranged on plate face edge one side was opened, and the striker that is positioned on the plate face edge will collide, at this moment, motor will stop operating because of outage, and clean like this another side just is presented at the moment, can use for continuing.Simultaneously, when motor rotates, write the one side of full word and can rotate, rotate to the special pens erasure, in the process that special pens is wiped and the plate face rubs, the font on the plate face will be wiped along with gear.Be arranged on plate face edge magnetic glass and plate face on every side and all have magnetic, will produce interattraction, stable when writing, do not move swiftly.The water tank that is provided with below projection cloth box can regularly be wiped water spray to special pens, makes it keep clean, and it is quite convenient that whole process is used.
Adopt beneficial effect of the present invention to show:
One, adopts the electric magnetic device, after writing full word on the plate face, press power switch, the plate face just rotates under the drive of gear, and when the plate face turned to another side, the impact switch that is arranged on plate face edge one side was opened, at this moment, motor will stop operating because of outage, and clean like this another side just is presented at the moment, can use for continuing.Simultaneously, when motor rotates, write the one side of full word and can rotate, rotate to the special pens erasure, in the process that pen is wiped and the plate face rubs, the font on the plate face will be wiped along with gear, easy to use.
Two, plate face top is provided with projection cloth, in special teaching with projection cloth in the projection cloth box toward drop-down, move the snapped-in position of plate face below to, on the clamp card, not the time spent, promptly available wind takes in projection cloth in the projection cloth box.Need not install repeatedly, use efficient and convenient.
Three, be arranged on plate face edge magnetic glass and plate face on every side and all have magnetic, will produce interattraction, stable when writing, do not move swiftly.And no dust pollution makes teaching more easy and convenient.
