Also has the Chinese invention patent < < magnetic adsorption writing board > > that the patent No. is CN200710011437.5, comprise plate face and magnetic pen, slot is inwardly offered in plate face front, settles magnetic spheres in slot; Magnetic pen is column structure, and two ends are comprised of the N utmost point and S utmost point magnetic patch; At the plate face back side, controllable magnetic field is set.When selecting N extremely nib write, N is the close plate face of nib extremely, attract each other with the S utmost point on magnetic spheres surface in slot, spheroid from sucking-off in slot pipe and be stuck in opening part, by the imaging of pixel principle, is convenient to observe, while removing writing, can closing coil gauge tap, make coil electricity produce strong magnetic field, by magnetic field, all magnetic spheres are all sucked back in slot pipe.It is by the principle design of magnetic absorption between magnetic pen and magnetic spheres, the feature with handling safety environmental protection, but complicated structure, spheroid due to plate face is also magnetic in addition, if run into ferrous metal, will adsorb,, if there is magnetic absorption in outer some sheet metal that can be useful on decoration etc. that puts of present child, the use of board can be affected, therefore a kind of board simple in structure, easy to use need to be developed.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of board simple in structure, easy and safe to operate and with low cost for the above-mentioned state of the art.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of board, comprise plate body, magnetic pen, it is characterized in that: on the front of described plate body, equidistant compartment of terrain is distributed with the conical shrinkage pool that the little base diameter of top diameter is large, the downward projection of described plate body front upper concave hole is latticed, in each shrinkage pool, be provided with the up and down steel ball of energy, the diameter of described steel ball is greater than shrinkage pool end face circular port diameter, when steel ball is moved up by the suction of magnetic pen, the end face of steel ball can stretch out shrinkage pool end face and can fasten on the end face that is positioned at shrinkage pool.
As improvement, on the internal perisporium on described shrinkage pool top, be respectively arranged with the annular slot that can improve steel ball position stability.
As improvement, the diameter of described steel ball is 3.5 ~ 4.0mm, and the aperture of described shrinkage pool is corresponding with steel ball to be fitted in together.
As improvement, the degree of depth of described shrinkage pool is 1 ~ 2cm, and the spacing between adjacent two shrinkage pools is 2 ~ 3mm.
Improve again, described magnetic pen comprises penholder and magnetic writerhead, and described magnetic writerhead is embedded in the groove of penholder front end, is provided with a spring in groove, this spring supporting, between the bottom of groove and magnetic writerhead's rear end, makes magnetic writerhead have the trend of protruding penholder all the time.
Improve, the positive below of described plate body or top are laterally arranged and stretch into and the convenient circular groove that takes out magnetic pen for placing the fixing strip-shaped clamp groove of magnetic pen, be provided with at the middle part of strip-shaped clamp groove to be convenient to point again.
Further improve the shrinkage pool that described shrinkage pool is same specification.
Further improve, described plate body is put together by front and back two boards face, passes through screw fixed with each other at front and back two boards.
Compared with prior art, the utility model has the advantage of: on plate body, offer the conical shrinkage pool that the little base diameter of top diameter is large, steel ball is set in shrinkage pool, attraction by magnetic pen is positioned at plate body surface by corresponding steel ball absorption, when steel ball need to be eliminated, as long as press steel ball with hand, or brush a lower body surface with a shell, steel ball will fall automatically, very convenient.The utility model is simple in structure, and good looking appearance is with low cost, greatly facilitates children's the drawing of writing, and uses safety and environmental protection.
