Abstract

The utility model relates to a multifunctional blackboard comprising a hollow board surface and a magnet pen, wherein a partition board is arranged in the board surface and is used for dividing the board surface into two layers, iron powder is evenly coated in an outer-layer space, a strip-shaped magnet is arranged in an inner-layer space, the strip-shaped magnet is perpendicular to the bottom edge of the board surface, the bottom end of the board surface is provided with an orthogonal edge, a sliding channel is arranged on the bottom edge of the board surface, the projective orthogonal edge extends out of the sliding channel, and the top edge of the board surface is provided with a plurality of lighting bulbs. When the multifunctional blackboard is used, the user uses the magnet pen to write on the surface of the blackboard, and the iron powder in an interlayer is absorbed on the surface of the blackboard by the magnet of a pen point to form characters; and when light is insufficient, the lighting bulbs can be used for lighting to increase light brightness. The multifunctional blackboard has the advantages of simple structure, convenience, sanitation, safe use, and the like.

Description

Multi-functional blackboard

Technical field the utility model relates to a kind of teaching aid, especially a kind of multi-functional blackboard.

The background technology blackboard is that the student learns necessary tool, and the teacher can explain exercise on blackboard.But present blackboard all has common defective, and that must use chalk to write on blackboard exactly, has so just caused great dust pollution, and the healthy of Faculty and Students in serious threat; And also there is the function simple question in present blackboard, and under the situation of insufficient light, people then can't use blackboard, have seriously limited the application time.In order to improve the problems referred to above, we provide a kind of multi-functional blackboard that can not produce dust pollution and illumination functions can be provided.

The summary of the invention the purpose of this utility model provides a kind of multi-functional blackboard, is used to solve the problem that normal blackboard pollutes easily and can't regulate light intensity.

For achieving the above object, the utility model multi-functional blackboard comprises that rectangle empty body plate face and nib have the pen of magnet, and there have dividing plate that it is divided in the plate face to be two-layer, evenly scribbles iron powder in the outer space; A bar magnet is installed in inner space, bar magnet vertical panel face base, its bottom is a right-angle side, and offers slideway at place, plate face base, outstanding right-angle side stretches out from slideway; At plate face top margin a plurality of lighting bulbs are installed, and the plate face is that whitish translucent material is made.

After adopting said structure, the user writes on the blackboard surface with the magnet pen, thereby by the magnet of nib the iron powder of blackboard interlayer is adsorbed on blackboard surface formation writing and figure; When cleaning, the bar magnet that can horizontally slip sucks back iron powder in the interlayer again by bar magnet, makes the plate face recover white again, can not see any writing and figure again at the plate face; When insufficient light, the user also can realize illumination by lighting bulb, strengthens light luminance, extends working time.

The utility model has the advantages that: simple in structure, convenient and healthy, safe in utilization, by magnet the suction-operated of iron powder has been prevented dust pollution, protected that the user's is healthy; And illumination functions can also be provided, improve service condition.

Description of drawings Fig. 1 is the overall structure schematic diagram of the utility model multi-functional blackboard.

The specific embodiment as shown in Figure 1, the utility model multi-functional blackboard comprises that the empty body plate of rectangle face 1 and nib have the pen of magnet, there have dividing plate 2 that it is divided in plate face 1 to be two-layer, evenly scribbles iron powder 3 in the outer space; A bar magnet 4 is installed in inner space, bar magnet 4 vertical panel faces 1 base, its bottom is a right-angle side, and offers slideway 5 at place, plate face 1 base, outstanding right-angle side stretches out from slideway 5; At plate face 1 top margin a plurality of lighting bulbs 6 are installed, and plate face 1 is made for white transparent material.
