Abstract
Magnetic writing board and write, erase tool.Relating to the cylindrical magnet is the magnetic writing board field of show media.Purpose is to provide to be had the clipboard of cylindrical magnet and writes and erase tool in a kind of plate.This clipboard and write, erase tool, comprise have boxwork and the magnetic writing board of putting into cylindrical magnet wherein and with the different magnetic pen of clipboard cylindrical magnet magnetic and with the identical blackboard eraser of plate cylindrical magnet magnetic.It has writing clear, write conveniently, can before plate, wipe local or single writing, advantage such as practical.Alternative present widely used traditional blackboard and chalk.
Description
The present invention relates to the cylindrical magnet is magnetic writing board and the magnetic writing pen and the magnetic blackboard eraser of show media.
At present, be abroad or domestic employed magnetic writing board all is to adopt magnetic to do show media, and make magnetic can be suspended on the display board as supporter with thick liquid, because this class magnetic writing board utilizes magnetic to make display material, thereby can not wipe writing in the clipboard front, can only behind plate, magnetic be sucked back to reach the purpose of elimination writing, so this class magnetic writing board can only large tracts of land be wiped writing on the plate, can't wipe indivedual writings, use very inconvenience, so can't in field research, use, only can be used for small-sized writing implement or toy for children.There is not actual use value.
The objective of the invention is to utilize the permeance of cylindrical magnet that the magnetic writing board that has cylindrical magnet in a kind of plate is provided.
The present invention also aims to provide a kind of and described magnetic writing board cylindrical magnet magnetic (near display floater magnetic on one side) different magnetic writing pens.
Another object of the present invention is to provide a kind of and described magnetic writing board cylindrical magnet magnetic (near display floater magnetic on one side) identical magnetic blackboard eraser.
The present invention is made up of magnetic writing board, magnetic writing pen and magnetic blackboard eraser three parts.
One, magnetic writing board of the present invention has structure 4 and 2 two kinds of versions of structure, wherein:
(1). structure 1 is by the middle plate that has boxwork and place the cylindrical magnet in the boxwork on the plate and place mao sand glass (or translucent lucite) the display surface base plate and the non-metal board of plate front and rear portions to form.Wherein cylindrical magnet can slide in boxwork, and the color of cylindrical magnet is different with the middle plate color that has boxwork simultaneously, utilizes both aberration contrasts, writing can be shown.Utilize the astigmatism effect of hair sand glass display floater (or translucent lucite), can the cylindrical magnet that be arranged in postlaminar part is firmly latent, reach the purpose of eliminating writing.
(2). another version of described magnetic writing board---structure 2 is by the middle plate that has boxwork and place on the plate cylindrical magnet in the boxwork and place prelaminar part and clear glass display floater at rear portion (or transparent organic glass) and non-metallic floor and charge into the interior opaque colored liquid of boxwork and form.Wherein the color of cylindrical magnet is different with middle plate color, and the color of opaque colored liquid is the same with middle plate color.The cylindrical magnet that utilizes opaque colored liquid will be arranged in postlaminar part conceals, and reaches the purpose of eliminating writing.
Two. the magnetic of the cylindrical magnet in the magnetic writing pen of the present invention, the magnetic of its writing end and magnetic writing board (magnetic of later described cylindrical magnet is the magnetic near display floater one end) is different.Utilize the principle that there is a natural attraction between the sexes between magnet will be arranged in the postlaminar part cylindrical magnet and be drawn onto prelaminar part, and the transmission display panel shows.
Three. magnetic blackboard eraser of the present invention, its magnetic of blackboard eraser magnet that is used for wiping is identical with the magnetic of magnetic writing board cylindrical magnet, and the cylindrical magnet that utilizes the same sex is repelled mutually between magnet principle will be arranged in prelaminar part back into the magnetic writing board postlaminar part.
Magnetic writing board of the present invention and write, erase tool, have simple in structure easy to use, can before plate, wipe the advantage of local or single writing, write and write the same with use chalk commonly used now with method for deleting, can satisfy most teachers and other Writer's writing styles, and can manufacture monoblock type bulk clipboard or utilize the sticking method of assembly to be combined into the bulk clipboard with fritter.Wide application of the present invention, practical, in case implement fundamentally to change the present situation of using the chalk teaching, keep the teaching environment cleaning.Make numerous teachers and students avoid the hardship of chalk dust.The drawing explanation:
This explanation is made up of magnetic writing board (see figure 1), a magnetic writing (see figure 2) and magnetic blackboard eraser (see figure 3).Each sequence number is respectively:
1.----has plate in the magnetic writing board of boxwork.
2.----cylindrical magnet.
3.----hair sand glass (or translucent lucite) display floater.
4.----non-metallic floor.
5.----opaque colored liquid.
6.----clear glass (or transparent organic glass) display floater.
7.----magnetic writing magnet.
8.----magnet lettering pen handwriting.
9.----can with the combined magnetic writing handwriting of propelling pencil, ballpoint pen or pen.
10.----linked up with.
----magnetic blackboard eraser magnet.
----magnetic blackboard eraser suede matter infantees.
----magnetic blackboard eraser handle.The present invention is achieved in that
When the magnetic writing pen when 3. the magnetic writing board display floater streaks on (or 6.), because the magnet in the magnetic writing pen is 7. different with cylindrical magnet magnetic 2. in the magnetic writing board, thereby cylindrical magnet is 2. under the effect of magnetic field suction, be drawn onto plate front portion 1. in the magnetic writing board, utilize cylindrical magnet 2. different with middle plate color 1., by aberration contrast, can the transmission display panel 3. (or 6.) demonstrate the vestige that the magnetic writing stroke is crossed.When needs are wiped on the plate writing, can be with magnetic blackboard eraser in 3. (or 6.) upward wiping of display floater, 2. magnetic is identical with cylindrical magnet owing to magnetic blackboard eraser inner magnet , so 2. cylindrical magnet is subjected to the effect of magnetic field repulsive force to be pushed back in the row magnetic writing board 1. rear portion of plate.When magnetic writing board is structure (seeing Fig. 1-1), then be to utilize a hair sand glass (or translucent lucite), display floater astigmatism effect 3. will be arranged in plate 1. the cylindrical magnet at rear portion will be 2. latent and, and reach the purpose of elimination writing.When magnetic writing board is structure 2 (seeing Fig. 1-2), then be to utilize opaque colored liquid 5. 1. the cylindrical magnet at rear portion is 2. latent lives with middle plate.Reach the purpose of eliminating writing.
Magnetic writing pen of the present invention also has structure 1 (seeing Fig. 2-1) and two kinds of versions of structure 2 (seeing Fig. 2-2): wherein structure 1 is plain edition, (7. an end slightly is narrower than the cylinder of the other end to its profile, can satisfy the custom that most teachers or writer use chalk to write for a long time in order to have magnet.Profile is that structure 2 is pocket, and its handwriting 9. can be combined with propelling pencil, ballpoint pen, pen.10. hook can be easy to carry with the magnetic writing pen hanging in pocket, easy to use.
Magnetic blackboard eraser of the present invention is made up of handle magnet and the suede matter infantees that wraps in magnet outside, its medium staple matter infantees be used for preventing magnet and display floater 3. (or 6.) directly contact.
