Abstract
An environmental protection and energy saving teaching word pad does not need chalks or gel ink pens and is characterized in that a large number of cylindrical small holes are formed on the back side of a transparent face plate, and colored soft magnetic small cylinders are correspondingly inserted into the small holes. During writing, the small cylinders are sucked out through a magnet arranged on the transparent face plate to form writings. When the writings are needed to be erased, the magnet sucks the small cylinders into the small holes to be hided from the back side of the small holes.
Description
Technical field: the present invention relates to a kind of teaching board, particularly a kind of environment-friendly energy-saving teaching board that does not need chalk also not need free ink pen.
Technical background: the teaching board that existing school uses has two types, and a kind of is traditional blackboard, the blackboard that just utilizes chalk to write in the above.This traditional blackboard in use owing to need to use chalk, and the use of chalk must cause a large amount of chalk dusts to fly away everywhere, pollutes the classroom, uses the teachers and students of this traditional blackboard that potential health threat is arranged everyday; Second kind of teaching board is exactly the blank of now promoting the use of, this blank does not use chalk and is to use free ink pen, avoided the shortcoming of traditional blackboard, but be to use free ink pen after blank writes, to need water spray to blank, could wipe that writing, and spray can't be common water but the liquid medicine of specialty configuration, and the blank that nuzzles up with this liquid medicine spray can't continue to use at once, otherwise not only nib skids but also the writing write also can be with the liquid medicine reaction that remains on the blank, makes that to write on that the handwriting is blurred on the blank unclear; The third teaching board is also promoted the use of, and it is exactly electronic whiteboard, and the shortcoming of using electronic whiteboard is first will consume energy, and second can not want to use with regard to usefulness, and the 3rd needs to be grasped certain technical ability could use.The present invention is exactly the environment-friendly energy-saving teaching board that designs for the shortcoming that remedies above teaching board existence.
Technical scheme: basic structure of the present invention and technical characterictic are: a large amount of column type apertures is set behind a transparent panel, the coloured soft magnetism paxilla of corresponding insertion in the aperture, with magnet the paxilla sucking-off is formed writing at transparent panel when writing, when wiping writing, paxilla is sucked stash in the aperture with magnet in the aperture back and get final product, specific embodiments is: the sheet metal that comprises two blocks of nonmagnetic substances, foam or other non-magnetic filler materials, a transparent panel of being made by glass or other transparent materials, the white paxilla that a large amount of soft magnetic materials is made, frame, long magnetic stripe, article two, long magnetic stripe drags rail and magnetic pen etc. partly to form, requiring the metal sheet surface of two blocks of nonmagnetic substances is black, concrete structure and technical characterictic are: at first be filled into foam or other non-magnetic filler materials in the middle of the sheet metal of two blocks of nonmagnetic substances equably and sticking compressing, whole sheet metal face up vertically down gets out countless apertures closely then, the shape of aperture cross section is identical with the cross section of the paxilla of being made by soft magnetic material, but the cross-sectional area of aperture is bigger slightly than the cross-sectional area of paxilla, the degree of depth of aperture is also longer than the length of paxilla, the white paxilla of then soft magnetic material being made inserts aperture correspondingly again, the transparent panel that the lid lastblock is made by glass or other transparent materials, and press frame four limits of whole teaching board are fixed, drag two long magnetic stripes rail to be separately fixed at teaching board upper and lower behind at last, and drag at two long magnetic stripes and vertically to load onto a long magnetic stripe that moves freely about can be in dragging rail between the rail and get final product; Can present motley effect in order to make on the board, the color of paxilla also can be motley.Here it is environment-friendly energy-saving teaching board.
Operation principle: can use on the wall this environment-friendly energy-saving teaching board is fixing, only need pick up magnetic pen during use as using blank gets final product in the transparent panel drawing of writing, because magnetic pen is magnetic, therefore use magnetic pen when transparent panel writes drawing, the magnetic pen nib touches transparent panel, paxilla under the transparent panel in the aperture will be come out by the magnetic attraction of magnetic pen nib one after another and one be pressed on the transparent panel lower surface, and paxilla itself is coloured, the place that the magnetic pen nib streaks transparent panel will be formed corresponding coloured vestige by many paxillas that suck out, thereby presents corresponding word or picture; And in the time need erasing the vestige of these words or picture, the long magnetic stripe that only needs mobile board back, the back that makes long magnetic stripe be close to board skims over and gets final product, the aperture rear of withdrawing stashes because the paxilla when long magnetic stripe is close to the back of board and is skimmed in the aperture also can be by the magnetic attraction of long magnetic stripe, and staying word on the board or the vestige of picture originally will disappear because of the hiding of paxilla.This wherein because paxilla is made with soft magnetic material, does not have magnetic in the time of obsolete, do not have influencing each other of magnetic field at ordinary times each other, does not therefore have board later magnetic loss problem for a long time yet.
Social benefit: this environment-friendly energy-saving teaching board does not need chalk, free ink pen when using, do not need electricity consumption yet, at any time available, there is not dust pollution not have hazards of electromagnetic radiation yet, its design concept has really embodied environmental protection and energy saving and human nature service theory, can use the teachers and students of this environment-friendly energy-saving teaching board to feel more warm fully, will have bigger facilitation for the harmonious society that builds environmental protection and energy saving.
