Abstract
The utility model discloses a magnetic writing board which is characterized in that a faceplate is approximately in a transparent form. A soleplate is a magnetic plate, and a plurality of hollow cavities are arranged between the faceplate and the soleplate. A magnetic sheet matched with the hollow cavity is put in each hollow cavity. When people write on the magnetic writing board, a magnetic pen with a P pole and an N pole at the two ends is used and the magnetic pen moves according to the strokes of a character. The magnetic sheets in the hollow cavities roll over under the action of the attraction or the repulsion of the magnetic pen to form the character. Thus, the dust pollution can not happen.
Description
The utility model relates to the technical field of the board of stationery class, specifically a kind of dustless magnetic wordpad.
Existing blackboard or board mostly need chalk or special pens to write, and adopt chalk to write and have dust pollution when wiping, and be influential to physical and mental health, if adopt special pens to write, though dust pollution is less, the loss of special pens is bigger.
The purpose of this utility model is to provide a kind of magnetic wordpad, and it is no dust pollution when writing with wiping.
The technical solution of the utility model is achieved in that magnetic wordpad, it mainly comprises panel and the base plate that has frame, it is characterized in that: the approximate transparence that is of panel, base plate is a magnetic sheet, between panel and base plate, be provided with some cavitys, in each cavity, all place a magnetic sheet that matches with cavity.
The utility model is owing to be arranged to magnetic sheet with the base plate of board, between panel and base plate, be provided with some cavitys, in each cavity, all place a magnetic sheet that matches with cavity, the two sides of this magnetic sheet is different color, when writing, adopt two ends to be respectively the magnetic pen of P, the N utmost point, move magnetic pen by the stroke of word, each magnetic sheet in the cavity produces upset and forms word in the attraction of magnetic pen or under repelling, thereby can not produce dust pollution.
Fig. 1 is the outline drawing of the utility model one embodiment
Fig. 2 is that the A-A of Fig. 1 is to cutaway view
Fig. 3 is the enlarged drawing of magnetic sheet
Fig. 4 is the schematic diagram of magnetic pen
Fig. 5 is a magnetic sheet switching process schematic diagram
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises panel 2 and the base plate 3 that has frame 1, it is different from prior art and is: the panel 2 approximate transparences that are, generally can adopt glass or lucite, base plate 3 is a magnetic sheet, this magnetic sheet is the S utmost point or the N utmost point towards the panel direction, between panel 2 and base plate 3, be provided with some cavitys 4, each cavity is not communicated with, be provided with spaced walls 7 between each cavity, rounded or 61 nonagons in the perspective plane of each cavity 4 among the embodiment between panel and base plate, global approximation is honeycombed, approximate the bottom of a pan shape or the semicircle of being of the bottom sectional of each cavity 4; In each cavity 4, all place a magnetic sheet that matches with cavity 5, the two sides of magnetic sheet 5 scribbles two kinds of bigger colors of contrast, as two kinds of colors of black and white, in order to prevent that magnetic disk card is in cavity, being convenient to magnetic sheet 5 simultaneously overturns in cavity, present embodiment is provided with two microtias 6 on magnetic sheet 5, between panel 2 and base plate 3, be provided with 84 cavitys 4, form small plate,, can make up according to size during use so that transportation is carried, as when needing repairing, can change easily, promptly only the small plate that damages be changed health, and need not change whole plate face; Matching with it needs to use magnetic pen 8, this magnetic pen 8 can merge with the magnetic wiping board, and promptly an end is a magnetic pen, and the other end is magnetic wiping board (using when wiping fraction), the mid portion of magnetic pen and magnetic wiping board can be made into the magnetic wiping board that is the S utmost point or the N utmost point, is used for wiping the large tracts of land part.
Character pattern procedure for displaying of the present utility model is: if the magnetic sheet of base plate is set to the S utmost point, magnetic sheet in the cavity simultaneously is a N utmost point painted black, another side is a S utmost point painted white, under nature, the N utmost point of magnetic sheet is inhaled mutually with the magnetic base plate, the S utmost point of magnetic sheet is towards panel, the plate face is white in color, when writing, when magnetic pen moved, magnetic sheet was subjected to the influence that polarity is the magnetic pen external force of the S utmost point, the magnetic pen of the magnetic sheet of the S utmost point and the S utmost point is repelled mutually to overturn, magnetic sheet after the upset is identical with the magnetic of magnetic base plate, and under the effect of repulsive force, the N utmost point of magnetic sheet is withstood on the panel place and is the stable state of black, the track that described magnetic pen is drawn, just form black literal or pattern, as the A word that forms among Fig. 1, in the place that magnetic pen streaked, though magnetic can involve the surrounding area, but other magnetic sheet so can not overturn, therefore will note choosing magnetic pen owing to inhale mutually with the magnetic base plate, magnetism intensity between magnetic sheet and the magnetic base plate; Its elimination recuperation is: the process of eliminating writing or pattern is opposite with procedure for displaying; be under the effect of magnetic wiping board of the N utmost point promptly in polarity; the magnetic sheet that is black overturns because of the identical mutual repulsion of magnetic; magnetic sheet after the upset is inhaled toward the cavity middle part by the magnetic base plate; the stable situation of plate face is white in color; recovery is finished; in this process; magnetic sheet may be drawn onto the panel place; all the magnetic with the magnetic wiping board is opposite but owing to other magnetic sheet on every side; can not overturn, after the magnetic wiping board nuzzled up, magnetic sheet can automatically reset.
Claims (4)
1, magnetic wordpad, it mainly comprises panel and the base plate that has frame, it is characterized in that: panel is approximate to be transparence, and base plate is a magnetic sheet, is provided with some cavitys between panel and base plate, all places a magnetic sheet that matches with cavity in each cavity.
2, by the described magnetic wordpad of claim 1, it is characterized in that: be provided with spaced walls between each cavity.
