Abstract
The utility model provides a dust-free writing board, comprising a base plate, a magnetic plate and a front plate, a magnetic powder layer on the front face of the front plate, wherein the back of the front plate is connected with the magnetic plate, and the back face of the magnetic plate is connected with the base plate. The features of the dust-free writing board are: reasonable structure design, convenient writing and long service life. The magnetic power layer is used as the plate surface of the writing plate and the color of the uncased front plate after squeezing out the magnetic power is used as handwriting, and any pen shaped hard things such as finger can write on the writing board in no need of chalk without dust generation, thus the teaching environment is protected and the teaching cost is also saved; and the magnetic power layer unlikely generates reflection and the handwriting is clear and visible.
Description
Technical field
The utility model relates to a kind of teaching aid, specifically a kind of no dust clipboard.
Background technology
Blackboard is a necessary tool in a kind of teaching process, because of its intuitively, characteristics are adopted widely by people easily, traditional blackboard need use chalk to write, and can form a large amount of dust when writing and wipe, these dust float in air, can teachers and students' health be constituted a threat to; And because traditional blackboard panel is more smooth, can produce reflective phenomenon, reflective when strong the student can't see the writing at reflective place clearly, influence teaching efficiency.In addition, the report about no dust clipboard was arranged once, but, can't normally write, so fail so far to apply because its structural design is unreasonable.
Summary of the invention
The purpose of this utility model provides a kind of no dust clipboard, and it does not need chalk to write, and can not produce dust, legibility, no-reflection phenomenon, long service life.
The utility model is achieved through the following technical solutions for achieving the above object: comprise substrate, magnetic sheet and header board, the header board front is provided with magnetic blow out coating, and the header board back side links to each other with magnetic sheet, and the magnetic sheet back side links to each other with substrate.The header board back side and magnetic sheet are bonding, the magnetic sheet back side and base plate bonding.Header board, magnetic sheet and substrate surrounding are along frame is installed.Header board, magnetic sheet and substrate adopt bolt to connect.Magnetic sheet is the magnetic rubber plate.Magnetic sheet has plastic plate, and magnet is installed on the plastic plate.
Advantage of the present utility model is: reasonable in design, write conveniently long service life; Use the plate face of magnetic blow out coating as clipboard, squeeze open the header board that magnetic exposes color as writing, all can write with hard thing of any lip pencil even finger, do not need chalk, teaching environment had both been protected in no dust generation, had saved instruction cost again; Magnetic blow out coating can not produce reflective, and writing is high-visible.
Description of drawings
Fig. 1 is the utility model structural representation; Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
The primary structure of no dust clipboard described in the utility model comprises substrate 3, magnetic sheet 2 and header board 1, and header board 1 front is provided with magnetic blow out coating 5, and header board 1 back side links to each other with magnetic sheet 2, and magnetic sheet 2 back sides link to each other with substrate 3.This structure can be finished goal of the invention described in the utility model, and can reach result of use preferably.The color of header board 1 described in the utility model should have big aberration with the color of magnetic blow out coating 5, is convenient to discern writing to reach, and makes writing purpose clearly, usually header board 1 is designed to white.
The connection of substrate 3 described in the utility model, magnetic sheet 2 and header board 1 can be adopted multiple mode, for example: can adopt adhesive bonding or adopt fixture closely to connect.In order to make the connection between each plate not produce the gap, reach firmly evenly and connect, and keep the globality of each plate, can adopt adhesive positive bonding with the back side of header board 1 and magnetic sheet 2, again that the back side of magnetic sheet 2 and substrate 3 is bonding mode.This structure also has the advantage that manufacturing process simplifies except that above-mentioned advantage.For further reduction environmental pollution, and make the connectivity robustness of each plate better, improve service life, can adopt bolts to connect header board 1, magnetic sheet 2 and substrate 3, and each plate is closely linked to each other, to reach result of use preferably.
The further scheme of the utility model is: in the surrounding of header board 1, magnetic sheet 2 and substrate 3 along frame 4 is installed, this structure can fixed suspender, simultaneously, more further advantage is, making each plate carry out close and firm by frame 4 links to each other, and can change each plate easily, particularly when magnetic sheet 2 magnetic descend, conveniently detachable.
Another preferred version of magnetic sheet 2 described in the utility model is: magnetic sheet 2 has plastic plate, and magnet is installed on the plastic plate.This magnetic sheet sound construction, service life is longer relatively.
The utility model can use hard thing of any lip pencil or finger to write on magnetic blow out coating 5 in use, and the magnetic at the place of writing is by hard thing or point crowded opening, and exposes the white of header board 1, forms writing; When needing to remove writing, can adopt objects such as cylinder or scraper plate that magnetic blow out coating 5 is floating, all cover header board 1 and get final product.
