Abstract

The utility model discloses a multi-color magnetic writing board. Existing magnetic writing boards can be only used for writing with a single color. Thus, the existing magnetic writing boards are suitable for writing. If the existing magnetic writing boards are used for drawing or in places where require a plurality of colors, apparently the color is too monotonic. The utility model uses principles of repulsion and attraction of magnets. End surfaces of both magnetic poles of magnetic granules used as displaying carriers are respectively printed with different colors. A plurality of color zones are formed by a plurality of magnetic granules in different colors. Writings in a plurality of colors can be sharply written on the board by a magnetic pen with two polarities. The utility model has the advantages of convenient operation, simple structure, low cost and long service life. The multi-color magnetic writing board is particularly suitable for common presentations, writings and drawings.

Description

Multi-colour magnetic writing board

The utility model relates to a kind of polychrome magnetic writing board.

The plate face of existing magnetic writing board is made of transparent panel, grid, base plate adhesive seal, and its grid is made up of the identical little lattice of marshalling shape, and the magnetic and the milky suspension of black is housed in each airtight little lattice.When writing with the permanent magnet nib touch panel of magnetic pen, the magnetic in its little lattice of the zone of all magnetic pen processes is drawn onto the internal face of panel, thereby demonstrates the writing of black on panel.Attract the magnetic in the little lattice to arrive base plate and the cancellation writing by the erasion bar magnet under the movable base plate.This magnetic writing board can only be write a kind of writing of monochrome.This be used for writing still can, as be used for painting or be used for the occasion that needs many colors to show, obviously too dull.

The purpose of this utility model provides the polychrome magnetic writing board of a kind of suitable do demonstration and the usefulness of writing, paint.It can clearly write out the writing of multiple color, and is easy to use, simple in structure, can solve the deficiency of existing board to a certain extent.

The utility model is to realize like this, the magnetic grain that can show carrier in the conduct of its space free activity is arranged in the little lattice of the clipboard face that constitutes by transparent panel, grid, base plate sealing, its magnetic grain becomes bar shape, wears into different colors at the end face branch of N-S two magnetic poles.The nib of writing magnetic pen has two magnetic poles of N-S respectively.Write and utilize the principle that the permanent magnet same sex is repelled each other, there is a natural attraction between the sexes, the N utmost point or the S utmost point with magnetic pen are write on panel, the magnetic grain and the magnetic pen that can attract to be passed through in the regional little lattice make progress for different in nature end face, and inhaled toward the internal face of panel and demonstrate writing, the polarity of transposing magnetic pen nib can be write out the writing of different colours respectively.

Magnetic grain in the clipboard can into several different colors by subregion, just grid is divided into several zones, magnetic grain in each regional little lattice the color difference, cooperate the bipolarity magnetic pen on panel, can write out the writing of the multiple color of pure color and subregion simultaneously like this.

The utility model is compared with existing magnetic writing board, and following advantage is arranged:

Except writing function, have the effect of double-colored and simple and easy polychrome again concurrently with common clipboard.As long as colour changing is transposing nib, uses very conveniently, because of simple and reliable for structure, cheap, long service life, is particularly suitable for doing popular style and demonstrates and the apparatus of writing, paint.

The utility model is further described in detail by the following drawings and embodiment:

Fig. 1 is the structural representation of polychrome magnetic writing board.

Fig. 2 is the structural representation of magnetic pen.

With reference to the clipboard structural representation of Fig. 1, the panel of clipboard (1) is made with transparent hard plastic sheet.Grid (2) is by specification machine-shaping and the bonding one-tenth grid of transparent plastic sheet by required little lattice, and little lattice can be various geometries, preferably adopt honeycomb and criss-cross.Base plate (3) is made with transparent or other hard plastic sheet.Earlier grid and panel sealing are bonded into one, adhesion process should keep the size of each little lattice, is preferably in to carry out bondingly under the shaper control, is out of shape to prevent little lattice.Be placed with magnetic grain (4) in each little lattice, the magnetic grain becomes bar shape, and its size Ying Yineng free activity in the space of little lattice is advisable.The most handy fluorescent material of the dyed layer of two magnetic pole end faces (5), it is painted to adopt coating or other technology to carry out, and it is bonding base plate and grid and edge to be carried out polymerization fill with milk-white coloured suspension in each little lattice after, becomes the clipboard face of a sealing.Erasion bar magnet (6) under the base plate is fixed on the gangbar (7), can control the displacement erasion in case surface by gangbar.Casing frame (8), all available polystyrene of shell bottom (9) and gangbar or ABS engineering plastics are through injection mo(u)lding.

With reference to the magnetic pen structural representation of Fig. 2, the nib of magnetic pen has two magnetic poles of N-S.Magnetic pen can be made has extremely nib (11) and the S Double-nib magnetic pen of written (12) extremely of N.Penholder (10) is used injection molding, and bar magnet (13) is housed in the nib, and the magnetic pole outward of the bar magnet in two nibs is opposite.Magnetic pen also can be made other the form such as the magnetic pen of the movable two magnetic poles of single head.

Claims

1, a kind of polychrome magnetic writing board, comprise magnetic grain, suspension and erasion bar magnet in grid, base plate and the little lattice of forming by transparent panel, by little lattice, write magnetic pen and formed, it is characterized in that the magnetic grain in the little lattice becomes bar shape to wear different colors at the end face branch of two magnetic poles of N-S, the nib of magnetic pen has two magnetic poles of N-S respectively.

2, clipboard according to claim 1 is characterized in that said magnetic pen with two magnetic poles can make and have extremely nib and the S Double-nib magnetic pen of nib extremely of N.
