Abstract

The utility model relates to a structure of magnetic drawing board, and the drawing board is composed of a transparent plastic face plate, a bottom board and a honeycomb-shaped gridding. The gridding is filled with white glue solution having a certain yield value, and magnetic powders; the magnetic powders have different magnetic forces, and the colors of the magnetic powders are different from each other in dark and light. When a magnetic pen is moved on the board surface, a picture with suitable shade of colors can be formed, and the picture can be modified and erased by a magnetic eraser; the magnetic drawing board has no pollution and can be used repeatedly.

Description

Constructure of magnetic drawing board

The utility model belongs to the stationery class, is a kind of magnetic picture-drawing device.

Always ink and wash is all drawn on blank sheet of paper with black pigment, and this is not easy to revise and can not use repeatedly.Come writing words and figure with the black magnetic, at first put forward 1978 " spy opens clear 53-127032 " by Japanese Pilot company the earliest.Its magnetic writing board is the top and bottom surface that two transparent plastic sheets are bonded at boxwork, is full of white glue and a small amount of magnetic in the grid of sealing.Because glue has certain yield value, when magnetic pen is mobile on the plate face, can form stable literal and figure, wipe the mobile overleaf cancellation that gets final product with magnetic.Its major defect is that glue is poor to the restraining force of the magnetic line of force, and literal and the pattern edge write are scared, and be continuous inadequately, stroke intersect with near the time mutual interference is big mutually, image quality is poor, can only be as toy for children, and effect is also undesirable.

Existing magnetic writing board all is that main purpose is made with the writing words, identical and the solid colour of magnetic magnetic force that adopts, in the hope of trying to achieve in white and black writing effect, be not the ink magnetic drawing board that purpose designs and produces also in the world up to now with the drawing.

In Chinese ink painting,, need with dense, light, dried, wet four kinds of techniques of writing in order to show the depth level of personage and scenery.The utility model designs according to these specific (special) requirements, and at the shortcoming that has magnetic writing board now, is improved technically, to improve the visual readability and the continuity of stroke, reduces the influence of phase mutual interference.

The purpose of this utility model is achieved through the following technical solutions.

The utility model comprises a magnetic sheet, different magnetic wiping and the magnetic pens of several magnetic force.Magnetic sheet is a boxwork plate with the transparent plastic sheet sealing.Be full of white glue and an amount of shade black magnetic different in the grid with variation of magnetic force with certain yield value and viscosity.It is a flat bar magnet that magnetic is wiped, and magnetic pen is made up of the nib of penholder and permanent magnet.Strong magnetic force magnetic pen can be a little less than the magnetic force and saturate magnetic is attracted to the plate face during drawing, the black lines that draw, and weak magnetic force magnetic pen can be of light color and magnetic that magnetic force is strong is attracted to the plate face, and grayish lines draw.But the magnetic of weak magnetic force is wiped the light gray on the cancellation panel, but and the magnetic of strong magnetic force is wiped all figures on the cancellation panel.

The utility model is a kind of new drawing boards, i.e. magnetic ink drawing board.It is convenient to revise and cancellation, and dustless, pollution-free, no consumption can use repeatedly.Use the different magnetic pens deep or light suitable picture that can draw, when drawing, change magnetic pen apart from the distance of plate face can draw by dense to light or by light to dense lines, and utilize the effect of the magnetic pen magnetic line of force can form special artistic effect.The utility model can be widely used in aspects such as drawing teaching, artistic decoration, family life and commercial advertisement.

Description of drawings:

Fig. 1 is a vertical view of the present utility model;

Fig. 2 is a cutaway view of the present utility model;

Fig. 3 is a magnetic pen structure chart of the present utility model;

Fig. 4 is that magnetic of the present utility model is wiped structure chart;

Fig. 5 is a magnetic pen drawing design of the present utility model;

Fig. 6 is that magnetic of the present utility model is wiped elimination chart.

As depicted in figs. 1 and 2, the utility model is made up of panel (1), base plate (2), boxwork (3), glue (4), magnetic (5) and frame (6).Wherein panel (1) and base plate (2) are transparent plastic sheet, and boxwork (3) is made through bonding, incision and stretching with the plastic sheet of 0.05～0.10 millimeters thick.The grid height is generally 0.8～2.0 millimeter, 4～6 square millimeters of mesh areas.Panel and base plate be bonded in make the boxwork plate on the grid.Be full of white glue (4) and magnetic (5) in the grid with certain yield value and viscosity.Glue is that water or oil are made dispersant, as thickener, is equipped with that a spot of titanium dioxide makes with bentonite, silicon dioxide powder, calcium carbonate etc.The color of magnetic has black and grey, and has different magnetic force, and the granularity of magnetic is 10～200 microns ,/100 milliliters of glues of about 15～30 grams of consumption.Each piece drawing board has the magnetic pen of a few Zhi Butong magnetic force, and magnetic pen is made up of plastic bar (8) and nib (7).Nib is a permanent magnet, and its diameter is 0.3～8.0 millimeter, magnetic force 300～2000 Gausses.It is to be bonded at plastic handles (10) with flat permanent magnet (9) to go up formation that magnetic is wiped.The back side that it can be contained in sheet frame (6) also can individualism, and the magnetic force that magnetic is wiped is 300～1500 Gausses.Each piece drawing board has the magnetic of two, three different magnetic force and size to be wiped, and not only can smear large-area dark-background but also can be from the figure of the different depth of back side cancellation on panel.

Large-area its base plate of ink magnetic drawing board can adopt and be stained with one deck porous plate earlier, is stained with a slice plastic plate again after injecting glue, to improve the quality of sealing.The nib of magnetic pen can also can adopt the electromagnet that can regulate variation of magnetic force with permanent magnet.The drafting of picture can be manual also can be electronic.Can on large-area ink magnetic drawing board, duplicate famous painting by the existing famous painting of optoelectronic scanning, and can develop into electronic ad system.The utlity model has wide practical value.

Claims

1, a kind of structure of ink magnetic drawing board, it is made up of panel (1), base plate (2), boxwork (3), glue (4), magnetic (5) and frame (6); It is characterized in that panel and base plate are transparent plastic sheet and are bonded at the compartment that constitutes many sealings on the boxwork, wherein be full of white glue and the different and different magnetic of shade of an amount of magnetic force with certain yield value.

2, according to the said ink magnetic of claim 1 drawing board, its base plate can be a plastic plate, also can be a porous plate and the composite plate that the plastic plate bonding forms.
