Description

Colored magnetic writing board

The utility model relates to a kind of cultural goods, specifically is a kind of clipboard.

In background technology, common have blackboard, noticeboard, billboard etc., but they all exist pollution, wasting phenomenon, in development, the magnetic writing board that children family uses appearred, and the true qualities magnetic exists with loose shape in plate, be the horizontal state when using, what use during erasion is a bar magnet, holds two ends and moves, this structure makes some problems that there is, as: color is single, and the size-constrained system of plate face can not be made local the modification in use, tracing is irregular, and erasion is not congruent.

The purpose of this utility model provides a kind ofly to be had multicolour and shows that area is adjustable, can vertically place and easy to use write, painting supply, to replace the noticeboard that use in blackboard that conventional teaching uses and unit, street, and be applied to reduce expenses pollution abatement on the billboard.

For achieving the above object, solution of the present utility model is such:

Colored magnetic writing board; comprise the framework (21) that has protection base plate (7); its special character is: by cell board (20); activity permanent magnets (8); Magnetic eraser (22); magnetic pen (23) is formed; wherein cell board (20) is by panel (1); panel (1) is gone up uniform dividing plate (2); and the sealing plate (3) of corresponding band groove with dividing plate (2) constitutes; panel (1); form sealing between dividing plate (2) and the sealing plate (3); uniform cavity; colored suspension emulsion (9) and colored iron sand (10) are housed in the cavity, and activity permanent magnets (8) is positioned at the inboard of protection base plate (7) and the gap that sealing plate (3) forms.Magnetic eraser (22) is to be connected with blackboard eraser handle (11) by screw (12) by magnetic board (13).

Magnetic pen (23) comprises ball-type magnetic pen and roller magnetic force spread pen, and the ball-type magnetic pen is made of spherical permanent magnet (18), penholder (19); Roller magnetic force spread pen by at least one permanent magnetic roll assembly of roll magnetic separator (16), passes from circle centre position with axle (17), and axle (17) two ends and connector (15) constitute flexible connection, and connector (15) other end is fixedlyed connected with magnetic force spread pen handle (14).

Colored suspension emulsion is by rilanit special, polyacrylamide, octanol, directly pigment is formulated.

Colored iron sand (10) is 60 orders～80 purpose particles.

Contain magnetic blow out coating (24) in the sealing plate (3).

Have a module unit plate (20) at least, include the sealing plate (3) and battenboard (4) the adhesive static immobilization that contains magnetic blow out coating (24) of magnetic blow out coating (24).

Battenboard (4) another side is to be bonded together with gripper shoe (5).

Gripper shoe (5) another side and gripper shoe base plate (6) are bonded together.

Panel (1) dividing plate (2) is disposable injection molded, gross thickness is that 3～15mm is thick, panel 1 thickness 0.5～1.5mm, on the panel (1) of one module unit plate (20) the dozens of cavity is arranged, can be polygons such as triangle, square, rectangle, hexagon, the length of side is 2-10mm, and dividing plate (2) thickness is 0.1～1.0mm.

Panel (1) and dividing plate (2) are selected transparent material for use, and other parts can be selected transparent or opaque material for use.

Activity permanent magnets (8) motion for the space thickness that activity permanent magnets (8) moves, should be convenient in protection base plate (7) inboard.

Colored suspension emulsion (9) composition is suspending agent, antisettling agent, antifoaming agent, pigment.Suspending agent can use commercially available hydrogenated castor wet goods, and antisettling agent can use commercially available polyacrylamide etc., and antifoaming agent can use commercially available octanol, aliphatic acid etc., and pigment is commercially available direct pigment.

Colored iron sand (10) is selected high-quality 60 orders-80 purpose iron sand for use, with commercially available acid dyes colouring.

The utility model has the advantages that:

1, pollution abatement, economical and practical: the blackboard of Shi Yonging, noticeboard, billboard etc. needed with chalk, paper, pigment etc. as the tracing material in the past, when erasion, chalk can bring dust pollution, paper goes out of use, pigment, poster colour are because of chemical articles such as use banana oil, gasoline, thus the health of being harmful to, contaminated environment.And colored magnetic writing board has overcome these shortcomings, utilizes inexhaustible magnetic force to carry out tracing, erasion, and expense is low, long service life.

2, easy to use: be not afraid of wind and weather, can be in indoor, outdoor use.Select suitable dimension, can make memo pad, drawing boards, noticeboard, blackboard and billboard etc.Can change color and written contents at any time again with writing with wiping.Use one or more to choose the cell board of background color and tracing look as required; the polylith cell board can be fixed with the magneticaction adhesive with battenboard; be assemblied into one, form a big tracing plate, for gaining in strength; convenient in carrying; can use the structure that adds gripper shoe,, look the smooth degree of gripper shoe face for guaranteeing the activity permanent magnets flexible motion of protection base plate inboard; can bonding more thereon one deck gripper shoe base plate, its smooth surface.Several structure effective areas, purposes is selected for use flexibly.Clipboard can horizontal also can vertically be placed, when not using because the use of colored suspension emulsion, the iron sand steady stability, (contain magnetic blow out coating in the sealing plate) suspending or be attached on the sealing plate near the sealing plate place, panel presents the color that background color is colored suspension emulsion, and during use, magnetic pen attracts colored iron sand, colored iron sand reaches the purpose of tracing with the mobile panel inboard that is adsorbed on of magnetic pen.When needing erasion, use Magnetic eraser, when blackboard eraser moved at panel surface, the activity permanent magnets that drives protection base plate inboard moved, and its suction by sucking back on the panel near sealing plate, reaches the purpose of erasion with iron sand.

3, tracing is clear, even, and erasion is complete: because the effect of suspension emulsion makes the iron sand dynamic flexible, be uniformly dispersed, and steady stability, so tracing is clear, writes Shi Buhui and disconnected stroke phenomenon occurs, during drawing, colourity is unified.Magnetic pen, as: ball-type magnetic force lettering pen and roller magnetic force spread pen all are designed to roller, for making magnetic force even, the permanent magnetic roll assembly of roll magnetic separator of spread pen can have a plurality of, when a few module unit plate assembly unit, even seam crossing is slightly uneven, can not influence the facile motion of pen yet, in order to avoid overstay at a place, iron sand compiles, and has played the effect of even absorption.Certainly, when less demanding, also can use the lines tracing without the magnetic pen of other structure of roller.Identical with the magnetic pen effect, the blackboard eraser surface design is a differential of the arc shape.

4, bright in luster, kind is many: select color by cavity injection different colours suspension emulsion and iron sand at cell board, on the clipboard of a module unit plate or the assembly unit of polylith cell board, can show multicolour writing and pattern like this, be suitable for teaching and use, also be suitable for the use of large board.
