CN2032552U - Rotable aromatic magnetic writing board and pen - Google Patents

Abstract

The utility model discloses a rotatable aromatic magnetic writing board and pen which is designed based on the principle of 'like polarities repel one another and opposite polarities attract each other' of the magnetic. Black writing with write background appears on the magnetic writing board when the magnetic writing pen gets close to the writing board; The writing can be wiped simply by getting the demagnetization mechanism close to the corresponding place of the writing board. Simultaneously, aroma can be emitted from the writing board. The utility model has the advantages that the chalks and the blackboard brushes are saved; the respiratory disease induced by the chalk dust can be avoided; the writing board is suitable for using in the open-air when raining or displaying in water because the handwriting can not be washed by the rain; the surface of the writing board can be regulated optionally according to the requirement of the writer.

Description

Rotable aromatic magnetic writing board and pen

The utility model relates to a kind of writing implement of culture and education and propaganda.

At present, blackboard is a kind of writing implement that generally uses, and adopts black floor mostly, directly writes with chalk.The major defect of this blackboard is: 1. when writing with wiping, chalk dust is bigger, is the inducement that produces breathing problem, diminishes user's physical and mental health.2. after blackboard is write white chalk person's handwriting, because light refraction, the bigger spectators' in visual angle, both sides eyesight there is certain influence.3. the chalk person's handwriting uses in the time of should not raining in the open or in the water easily by rain drop erosion.4. after in a single day blackboard installed and fixed, the size height was just immutable, and must can reuse inconvenience after the wiping after once having write.5. to consume a large amount of chalks and blackboard brush.

In order to overcome above-mentioned defective or deficiency, the purpose of this utility model provides a kind of rotating fragrant magnetic writing board and lettering pen of writing, be without the brush wiping, after writing white gravoply, with black engraved characters without chalk.

The utility model is made up of clipboard (1) and lettering pen (19) two large divisions.Clipboard (1) is made of clipboard panel (2), clipboard base plate (3), honeycomb core plate (4), main transmission drum axle (5), main transmission drum (6), auxiliary driving drum shaft (7), auxiliary driving cylinder (8), manual handle (9), reinforcing plate washer (10), left tension force fixed bar (11), right tension force fixed bar (12), demagnetization plate (13) and annular driving band (14).Main transmission drum (6) and auxiliary driving cylinder (8) are housed respectively on main transmission drum axle (5) and auxiliary driving drum shaft (7), and manual handle (9) is loaded on the right-hand member of main transmission drum (6).In the and arranged on left and right sides of main transmission drum axle (5) and auxiliary driving drum shaft (7), left tension force fixed bar (11) and right tension force fixed bar (12) are housed respectively.Annular driving band (14) is the closed ring structure along the outer surface of main transmission drum (6) and auxiliary driving cylinder (8).I-shaped reinforcing plate washer (10) is equipped with in the central space of the annular driving band (14) between main transmission drum (6) and auxiliary driving cylinder (8) and the bottom of main transmission drum (6), and demagnetization plate (13) is contained on the reinforcing plate washer (10) of main transmission drum (6) below.Clipboard base plate (3) is fixed on the annular driving band (14), and honeycomb core plate (4) is fixed on the clipboard base plate (3), and clipboard panel (2) covers on the honeycomb core plate (4).Have several regular hexagon honeycomb core chambers (15) on the honeycomb core plate (4), in each honeycomb core chamber (15), to the direction of writing panel (2) black magnetic particle (16), fragrant thickener (17) and white coloring agent (18) are housed respectively according to clipboard base plate (3).The spacing of per two honeycomb core chambers (15) is less than 1 millimeter.Lettering pen (19) is made of magnetic nib (20), hand-held penholder (21) and demagnetizer (22).Demagnetization plate (13), demagnetizer (22) are identical with the magnetic of black magnetic particle (16), and magnetic nib (20) the then magnetic with black magnetic particle (16) is opposite.Clipboard panel (2) is made by transparent plastics or lucite, honeycomb core plate (4), clipboard base plate (3) and reinforcing plate washer (10) are made by plastics or wood materials, main transmission drum (6), auxiliary driving cylinder (8) and manual handle (9) are made by plastics, metal or wood materials, and annular driving band (14) is made by materials such as rubber, resin, plastics or canvas.

When writing, in case the magnetic nib (20) of lettering pen (19) is near the respective cell core chamber (15) of honeycomb core plate (4), according to the magnetic principle of " same sex is repelled each other, and there is a natural attraction between the sexes ", black magnetic particle (16) is just pressed close to clipboard panel (2), the black vestige occurs.When needs are eliminated the black vestige, only need the approaching position that need eliminate of the demagnetizer (22) of lettering pen (19), black magnetic particle (16) resets rapidly, and vestige is eliminated automatically, and white background color recovers.Inwardly rotation manual handle (9) drives main transmission drum (6) and rotates, and drive annular driving band (14) and clipboard base plate (3), honeycombed sheet core (4), the clipboard panel (2) fixed on it are done motion from bottom to top together.During the clipboard after writing (1) process demagnetization plate (13), original black vestige of having write is just eliminated automatically.When if the area of clipboard (1) is big, the available corresponding electric device of manual handle (9) is replaced.

The utlity model has following characteristics: 1. no dust pollution, and can often send faint scent for a long time, and both can avoid because of chalk dust brings out breathing problem, the condition of also can improving environmental sanitation, social benefit is good.2. written trace can be by rain drop erosion, can be when rainy shows in the open-air or water to use.3. the black mark of white background, does not produce light refraction at good contrast, and spectators' eyesight is unaffected.4. contactless writing, and writing position can regulate arbitrarily, and easy to use, applicability is good.5. can save chalk and blackboard brush, better economic benefit.
