Abstract
The utility model relates to a combined teaching tool used for line-surface perpendicularity. The combination teaching tool is realized as follows: the combined teaching tool comprises a square connector, a magnet, a connecting iron wire and a transparent plate; concave pits are arranged on six surfaces of the square connector; the connecting iron wire is arranged in the concave pits of the square connector; a through-hole is arranged on the transparent plate; and the magnet is arranged at one end of the connecting wire, which passes through the through-hole. The combination teaching tool has the advantages of simple structure and strong direct-viewing property, is conducive to training the spatial imagination power of students, and can solve other concepts or propositions in geometry teaching. In the utility model, only the line-surface perpendicularity is taken as an example, and the combined teaching tool can be flexibly applied in the actual conditions as required.
Description
Technical field:
The utility model belongs to the several teaching teaching aid, and particularly the line face is vertically used combined appliance for teaching.
Background technology:
At present some how much class hour of professor teacher, can only on blackboard, draw, because mapping in the plane, therefore geometric space image is difficult to the imagination, and at this moment teacher often will go to say repeatedly, has not only wasted the time, and teacher feels also that difficultly it is also very difficult that the student sounds.
The utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of line face vertically to use combined appliance for teaching, said line face vertically is achieved in that with combined appliance for teaching the line face vertically is made of square connector, magnet, connection iron wire, transparent panel with combined appliance for teaching, on six faces of square connector, be equipped with pit, be provided with the connection iron wire in the pit of square connector, be provided with through hole on transparent panel, the end that the connection iron wire passes through hole is provided with magnet.
The utility model has the advantages that: simple in structure, intuitive is strong, helps cultivating student's space imagining ability, can solve some other notion or proposition in the several teaching, here the utility model only vertically comes for example with the line face, in practice as required, and can be flexible and changeable.
Description of drawings:
Accompanying drawing 1 is the structural representation of square connector of the present utility model; Accompanying drawing 2 is one-piece construction synoptic diagram of the present utility model: 1-square connector 2-pit 3-connects iron wire 4-transparent panel 5-through hole 6-magnet
Embodiment:
With reference to attached Fig. 1 and 2, be described as follows: the line face vertically uses combined appliance for teaching by square connector 1, magnet 6, connect iron wire 3, transparent panel 4 constitutes, on six faces of square connector 1, be equipped with pit 2, be provided with in the pit 2 of square connector 1 and connect iron wire 3, in the field research demonstration, connect iron wire 3 and will have some, vertically use in the combined appliance for teaching at this line face, there are four to connect iron wire 3, article four, an end that connects iron wire 3 is located at respectively in the pit 2 of square connector 1, be provided with through hole 5 on transparent panel 4, through hole 5 can well-regulatedly be provided with a plurality of, and four connect the other end that iron wire 3 passes through hole 5 and are provided with magnet 6.
The utility model is simple in structure, and intuitive is strong, helps cultivating student's space imagining ability, can solve some other notion or proposition in the several teaching, here the utility model only vertically comes for example with the line face, in practice as required, and can be flexible and changeable.
