Abstract
The utility model relates to a magnetic writing and drawing board used for writing, drawing, and the presentation of a magnetic force line. The utility model comprises a bottom panel and an upper panel. A sandwich chamber is arranged between the bottom panel and the upper panel. The mixed powder of magnetic and non-magnetic materials with different colors is installed in the sandwich chamber. The utility model can be used to practice writing and drawing and to present the distribution of the magnetic force line vividly.
Description
The utility model relates to a kind of magnetic writing and drawing plate.
Existing magnetic wordpad is to be made of the base plate of a honeycomb and a transparent top panel, be placed with white liquid and black magnetic powder in the little space of its honeycomb, be provided with a magnetic stripe that can slide at the back side of honeycomb base plate in order to eliminate the writing on the board, though this magnetic wordpad is easy to use, but function singleness is made complicated.
The purpose of this utility model is to provide a kind of can the exercise to write, study painting and can demonstrate the magnetic writing and drawing plate that the magnetic line of force distributes visually.
The utility model is made of a bottom panel and a transparent top panel, by set edge sealing between bottom panel and the top panel edge, make to form an interlayer chamber between bottom panel and the top panel, the magnetic material of different colours and the mixed powder of nonmagnetic substance are housed in the interlayer chamber.
That advantage of the present utility model is is simple in structure, cost is low, easy to use, not only can practise writing and drawing, distribute but also can demonstrate the magnetic line of force.
Description of drawings:
1 is outside drawing of the present utility model among the figure;
Fig. 2 is a sectional structure chart of the present utility model;
1 is bottom panel among the figure, the 2nd, and top panel, the 3rd, interlayer chamber, the 4th, mixed powder, the 5th, edge sealing.
The utility model is described in further details with embodiment below in conjunction with accompanying drawing:
Edge between bottom panel (1) and the transparent top panel (2) is provided with edge sealing (5), and the magnetic material of different colours and the mixed powder of nonmagnetic substance (4) are housed in the interlayer chamber (3) between bottom panel (1) and top panel (2).
The utility model is even with the shop of the mixed powder (4) in interlayer chamber (3) earlier in use, writes or paints with a magnetic pen then, or demonstrate magnetic line of force distribution visually with magnet.
