Abstract
An electromagnetic blackboard comprises a blackboard face (1) and a blackboard groove (3) arranged below the blackboard face (1). An electromagnet is further arranged at the rear portion of the blackboard face (1) and an electromagnet switch (4), and the electromagnet switch (4) is arranged on an outer groove face of the blackboard groove (3). One to ten double-face iron blackboards (2) are further attached on the blackboard face (1) in matching mode. One to fifty circular iron bottom plates (5) are further attached on the blackboard face (1) in matching mode. The electromagnetic blackboard can present many contents by writing on the blackboard at one time, small blackboards can be fixed with good effects, combination forms are flexible and variable, and a teacher can be helped to present the contents of class teaching conveniently. In addition, hanging pictures or other presentation teaching contents can be fixed through the iron button plates.
Description
Technical field
The utility model relates to a kind of technical field of teaching aid, is specifically related to a kind of electromagnet blackboard.
Background technology
The blackboard that uses in the existing classroom instruction is generally the glass or the iron space of a whole page, and is fixed, and under the situation of having only a space of a whole page, the teaching board demo content is just very limited.If the teacher need increase the once content of demonstration; Then need supporting use small blackboard; And the fixing of small blackboard just becomes a problem; On the clean metope or on the blackboard surface through iron nail fixedly small blackboard perhaps be attached on the iron blackboard through magnet plate, but the cost of magnet small blackboard is higher, and service life is limited.
The utility model content
The purpose of the utility model is the deficiency to prior art, provides that a kind of writing on the blackboard demo content is many, combining form flexible, the electromagnet blackboard of good fixing effect.
The purpose of the utility model realizes through following technological means: a kind of electromagnet blackboard; Include blackboard surface and the blackboard groove that is arranged on the below; The back side of said blackboard surface also is provided with electromagnet; And being provided with electro-magnet switch, described electro-magnet switch is arranged on the outer well surface of blackboard groove.
Also supporting attaching is provided with the two-sided iron black plate of 1-10 piece on the described blackboard surface.
The also supporting attaching of described blackboard surface is provided with 1-50 circular iron button plate.
Compared with prior art the utlity model has following tangible advantage: this electromagnet blackboard can a writing on the blackboard be demonstrated more content on the whole; And fixedly small blackboard is effective; The form of combination is versatile and flexible, can help teacher to demonstrate the content of classroom instruction easily.Can also fix wall chart or other teaching demonstration content through iron button plate made of iron in addition.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1-blackboard surface, the two-sided iron black plate of 2-, 3-blackboard groove, 4-electro-magnet switch, 5-iron button plate.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is done further to describe in detail:
A kind of electromagnet blackboard as shown in Figure 1 includes blackboard surface 1 and the blackboard groove 3 that is arranged on the below, and the back side of said blackboard surface 1 also is provided with electromagnet, and is provided with electro-magnet switch 4, and described electro-magnet switch 4 is arranged on the outer well surface of blackboard groove 3.Be provided with like this, this electromagnet blackboard can be controlled the electromagnet that is arranged on blackboard surface 1 back side through electro-magnet switch 4, makes magnetic on the space of a whole page band of whole blackboard, can optionally attach some iron teaching aids then.
Also supporting attaching is provided with the two-sided iron black plate 2 of 1-10 piece on the described blackboard surface 1.Be provided with like this, this electromagnet blackboard can increase the content of courses of writing on the blackboard demonstration through the two-sided iron black plate 2 of supporting setting, and can combination in any use, and has improved the result of use of classroom instruction, and good fixing effect, long service life.
The also supporting attaching of described blackboard surface 1 is provided with 1-50 circular iron button plate 5.Be provided with like this, this electromagnet blackboard can fix some non-wall charts made of iron or other classroom instruction demonstration teaching aid through the iron button plate 5 of circle, increase further the scope of application of the utility model.
In a word, the utility model provide that a kind of writing on the blackboard demo content is many, combining form flexibly, the electromagnet blackboard of good fixing effect.The above; Be merely a part of specific embodiment of the utility model; The protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
