Description
Technical field the utility model relates to a kind of teaching aid, especially a kind of displaying realia of writing.
Background technology is well-known, and blackboard is one of teaching aid indispensable in the school instruction.But, be born so far from blackboard, continue to use integral slab face structure, in case after the plate face was all write completely, teachers and students can only could continue writing and teaching by blackboard wiping, and for the student, if in time do not copy writing on the blackboard, will certainly influence after class and review always.In addition, present blackboard can only could use by the external light source irradiation, is lacking under the situation of external light source, and blackboard has just lost self-acting.
The summary of the invention the purpose of this utility model provides a kind of multilayer pull illumination blackboard of writing the space and throwing light on of expanding.
The utility model mainly comprises the main board face, described main board face is the hollow plate structure, and both-side opening is offered many slideways respectively in both sides up and down at inner interlayer, according to the corresponding insertion polylith of slideway quantity pull plate face, at pull plate face outer surface mounting knob with the position; The top margin of main board face level forward extends, and fluorescent tube is installed in the section lower edge extending.
During normal the use, the user all inserts main board face inside to the pull plate face, only needs to carry out writing and teaching at the main board face and just can.If main board face write area is not enough, the user can continue to write from its inner pull plate face of extracting out, need not to wipe the writing of main board face.During dim light, the user can closed fluorescent tube switch, and fluorescent tube energising back luminous lighting illuminates the plate face, and bright teaching environment is provided.
Compared with the prior art, the beneficial effects of the utility model are: be widely used, rational in infrastructure, convenient and practical, operation is convenient, can expand to write and show area, use when being particularly suitable for examination, teaching, and possess illumination functions, can under no luminous environment, continue teaching.
Description of drawings Fig. 1 is a stereochemical structure sketch of the present utility model.
The specific embodiment is in stereochemical structure sketch of the present utility model shown in Figure 1, mainly comprise main board face 1, described main board face is the hollow plate structure, both-side opening, offer many slideways 2 respectively in both sides up and down at inner interlayer, according to the corresponding insertion polylith of slideway quantity pull plate face 1-1, at pull plate face outer surface mounting knob 3 with the position; The top margin of main board face level forward extends, and fluorescent tube 4 is installed in the section lower edge extending.
