Description
Technical field
The utility model relates to a kind of board, and a kind of magnetic force adsorption type board, belongs to teaching equipment technical field specifically.
Background technology
At present, in teaching, usually adopt blackboard, chalk as educational aid, concrete, blackboard or coat pitch-dark by plank or cement plate, or have the focussing glass of shirt black matrix to make.These blackboards can only by the chalk-writing taking lime as primary raw material, and dust is very large, and when erasing the board with blackboard eraser, dust can fly upward everywhere, also can cause health problem if sucked in lung by academics and students.It is blank that present board also has, it comparatively blackboard had greatly improved, but blank is substantially all plastic running surface coating white paint, Long-Time Service can make surperficial white paint come off, the vestige on surface is also had also to be difficult to wipe clean, use like this and just bother very much, secondly outward appearance also unsightly.
Utility model content
In order to solve the technical problem of existing existence, the utility model provides a kind of magnetic force adsorption type board, and this writing board structure is simple, thoroughly solves Faculty and Students' problem of sucking the chalk dust impaired one's health passive in teaching process.
Realize adopted technical scheme of the present utility model to be:
A kind of magnetic force adsorption type board, it is characterized in that, comprise panel and coordinate the writing pen write with panel, described panel is layer structure, be divided into three layers, top layer is the transparency glass plate for writing, middle level is the magnetic sheet for adsorbing with external magnets, bottom is the plane shuttering panels for supporting, and the outside of described panel is provided with sheet frame, and described sheet frame is provided with the penholder for fixing writing pen, described writing pen comprises penholder and nib, described nib is connected to penholder one end, and described nib is provided with magnetic patch, and the magnetic of described magnetic patch is contrary with the magnetic in middle level; Described board is furnished with blackboard eraser, is provided with the magnetosphere with the middle level magnetic same sex below described blackboard eraser.
Use principle: this board utilizes the different of the middle level magnetic of the magnetic of writing pen and board, write with writing pen, utilize the effect that there is a natural attraction between the sexes for magnetic force, the word write well is presented on transparency glass plate, after writing, utilize the effect of the magnetosphere of blackboard eraser and the magnetic repellence of middle level magnetic, write word can be wiped.
The beneficial effects of the utility model: the utility model structure is simple, cost of manufacture is low, pollution-free, simply easy to operate, laborsaving, can realize promoting widely, well solve Faculty and Students' problem of sucking the chalk dust impaired one's health passive in teaching process.
