Description

Colour liquid does not have dust multipurpose clipboard and writing pen

The utility model relates to didactic works and writes clipboard and writing appliances thereof such as plate, publicity board, telegraph board and message board.

So far, home or overseas no matter, teaching is with waiting clipboard to remain the so-called blackboard that the flat board by timber or glass material constitutes, by means of the chalk writing words.Its shortcoming is: dust polluting environment, harm teacher and the student's who produces in 1. writing with chalk is healthy.2. general just black (blackboard color) white (chalk color) poor, relatively more dull of aberration, when blackboard after long-term use, fade gradually, it is eye-catching inadequately clear that the writing of writing out just becomes.Must use blackboard eraser when 3. removing writing, not only expend time in but also expend muscle power, but also be difficult to wipe clean, be difficult to differentiate (cause that aberration is very little) when writing again.

The purpose of this utility model just is to provide a kind of improved clipboard and writing pen thereof, and it can not produce dust, and handwriting is clear, goes word laborsaving fast.

The technical scheme of the utility model clipboard is: it comprises the fixing base plate of using, be inlaid in the netted substrate that has many grids on this base plate, inside each grid of netted substrate, all be loaded with the color masking liquid bulk and contain to go into to have and cover the colorful visualization particle that liquid has the magnetic of obvious aberration with this, a panel envelope is worse than above the netted substrate plate, color masking liquid bulk in netted substrate and the grid thereof and colorful visualization is granule sealed between panel and base plate, fixed base plate, netted substrate, panel is combined as a whole promptly to constitute and writes plate body, writes also to be provided with on the plate body by what magnetic material constituted at this and removes the word device.

The utility model writing pen comprises the nib that penholder, pen arm end are connected with, and wherein nib is a permanent magnet.

Before setting forth the utility model principle, at first will mention 2 general knowledge: the liquid that 1. has certain color density has certain screening effect, for example, when white solid is immersed in the blue look liquid and is positioned under the liquid level certain depth, white solid can be covered by blue look liquid and cannot see, when white solid floats gradually, can be gradually until clearly being displayed.2. magnetic material, can be adsorbed by magnet as the metal of iron.

The utility model utilizes above 2 general knowledge to finish just dexterously.Its principle is: when writing plate body and initially be hung on the wall, the colorful visualization particle of splendid attire (supposing as white) supposition all is in grid bottom (base plate one side in each grid in netted substrate, be color masking liquid bulk deep layer), so covered by color masking liquid bulk (being assumed to be blue look), can't see, color masking liquid bulk itself then sees through panel can be in sight, so whole front of writing plate body is the color (blue look) of color masking liquid bulk.Writing is to use the utility model writing pen, makes it nib (magnetic) paddling on panel and carries out.When written paddling, its magnetic force adsorbs the colorful visualization particle in the netted substrate grid of corresponding position and makes it attached or be close to panel (being in color masking liquid bulk top layer), and displays.Its effect is exactly to occur white writing on the plate body writing of blue look background.When will " wiping " when promptly removing writing, will rapidly the colorful visualization particle be adsorbed go back to netted substrate grid bottom (color masking liquid bulk deep layer) as long as start the word device that goes that constitutes by magnetic, make it to be covered by the color masking liquid bulk heavily again, the writing of also promptly writing above the plate body disappears.

As seen, the utility model can reach and not produce dust, and handwriting is clear, goes the quick labour-saving of word effect.In addition, the utility model low manufacturing cost, technology are simple, have popularizing value.
