Abstract

The utility model relates to a magnetic writing tool, which solves the defects that a writing pen is wasted easily, the writing pen generates dust pollution, the cleaning speed of a whole writing board is slow, and the cleaning effect is not clean. The utility model comprises a magnetic writing board and a magnetic pen, wherein, the magnetic writing board is provided with a transparent panel. The back side of the transparent panel is provided with a black board body with a hole, the hole is provided with a magnetic rod which can move backward and forward, and the magnetic pen is provided with a pen holder. The tail end of the pen holder is provided with a magnet, the front end of the pen holder is provided with a movable pen head, and a spring is connected between the magnet and the movable pen head in an elastic connection mode. The utility model has the advantages of strong and favorable writing and expressing effect, convenient recomposition, high speed of full cleaning, repeatable use, no dust pollution, and no loss of a writing pen.

Description

The magnetic writing device

The utility model relates to a kind of magnetic writing device.

The board that uses in existing school instruction mainly is dull and stereotyped, has plenty of with chalk and writes thereon, and also useful free ink pen writes thereon, and their common characteristic are when needs are rewritten, all to need to wipe person's handwriting with the hair eraser.Meeting with chalk produces very big dust, influences the healthy of people.The word of writing is many more, and it is many more that chalk consumes, and dust is also just big more.And when using free ink pen, because often erasable, can the certain pigment of accumulation on the eraser, cause wiping unclean, free ink pen is also with increasing of using and loss constantly.

The purpose of this utility model is to provide a kind of magnetic wordpad and magnetic pen to be used, and writes, rewrites, removes easy magnetic writing device.

For realizing the purpose of this utility model, described magnetic writing device, comprise magnetic wordpad and magnetic pen, magnetic wordpad has transparent panel, is provided with black plate body with holes in described transparent panel back, be provided with in the described hole can before and after movable bar magnet, magnetic pen has penholder, be provided with magnet at described penholder tail end, be provided with movable nib, between magnet and movable nib, be provided with the spring that elasticity is connected at front end.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the stereochemical structure view of magnetic wordpad.

Fig. 2 is the A-A partial sectional view of Fig. 1.

Fig. 3 is the B-B cutaway view of Fig. 2.

Fig. 4 is the topology view of magnetic pen.

Below in conjunction with accompanying drawing, the embodiment of the utility model magnetic writing device is described in further detail:

Magnetic writing device of the present utility model, comprise magnetic wordpad and magnetic pen, as shown in Fig. 1,2 and 3, magnetic wordpad has the square transparent panel of one deck 1, be provided with black plate body 2 in described transparent panel 1 back correspondence, black plate body 2 is provided with hole 4, and described hole 4 is a manhole, be arranged in array in black plate body 2, this structure mainly is to be convenient to make.Correspondence is provided with circular bar magnet 5 in hole 4, and bar magnet 5 can slide front and back in hole 4.Be provided with the backboard 3 that covers hole 4 at the back side of black plate body 2, make that bar magnet 5 can only be movable back and forth in hole 4.The two ends of bar magnet 5 are magnetic pole, and polarity is as one man put towards the direction of transparent panel 1.Be provided with white display part 6 at bar magnet 5 by transparent panel 1 end.White display part 6 is made of the end surfaces that Chinese white is coated in bar magnet 5.

As shown in Figure 4, magnetic pen has penholder 7, is provided with magnet 8 at described penholder 7 tail ends, is provided with movable nib 9 at front end, is provided with spring 10 between magnet 8 and the movable nib 9.In the described movable nib 9 retainer ring 12 that is fixed on the penholder 7 is arranged, be nested in the retainer ring 12 loose collar 11 and in loose collar 11 telescopic nib 13.Magnet 8 is opposite with the white display part 6 end magnetic of described bar magnet 5 by the polarity of movable written 9 ends, promptly when magnet 8 leans on the polarity of movable written 9 ends to be the South Pole, the white display part 6 end magnetic of bar magnet 5 are the arctic, like this when magnetic pen touches magnetic wordpad, just can be with the surface of 5 sucking-offs of the bar magnet in the magnetic wordpad to magnetic wordpad.Nib 13, loose collar 11 and retainer ring 12 adopt permeability magnetic material to make.As shown in Figure 2, place on the limit of all keeping right of the bar magnet in the magnetic wordpad.When nib was mobile on transparent panel, the magnetic force of magnet reached nib by spring, and the bar magnet of transparent panel back is drawn to the left side, and as shown in phantom in Figure 2, white display part sticks on the transparent panel, demonstrated the track that nib moves.Can write or draw at magnetic wordpad by being used just of magnetic writing device.When needs are revised person's handwriting, only need magnetic pen is inverted, the reversed pole that utilizes magnet is near transparent panel, just bar magnet can be advanced to the right, because bar magnet is arranged in the hole of black plate body, there is certain degree of depth in the hole, hole wall is a black, and the white display part of bar magnet end just cannot see.But thereby having realized Palingraphia, can repeat again to revise, and also pollution-free, lossless.When hand is firmly write, nib is subjected to the reaction force of transparent panel and retraction in penholder, along with the increase of exerting oneself, nib and loose collar and retainer ring form a large end face gradually, but produce firmly greatly at many bar magnets of transparent panel back sucking-off this moment, and person's handwriting is thick, the effect firmly little, that person's handwriting is thin.When need be with the person's handwriting full scale clearance of entire plate face, only need to make bar magnet wherein slide to backboard downwards magnetic wordpad certain angle that tilt, then the person's handwriting of plate face once all disappears, and removes quick comprehensively.

The utility model is than prior art, owing to be provided with the magnetic of bar magnet structure in the array arrangement hole of employing black plate body The property board, be arranged on the movable nib of magnet, the front end of penholder tail end, the magnetic pen of spring structure between the two, When being used, have the expression of writing effectively freely, it is convenient to rewrite, and removes fast comprehensively, can reuse no powder Dust pollution, the advantage of no writing pen loss.
