Abstract
The utility model particularly relates to a cube plane unfolding teaching aid, which belongs to the technical field of teaching aids, is simple in structure and convenient to use, and enables students to fully understand a cube structure. The cube plane unfolding teaching aid comprises a plastic bottom plate and six plastic cube plates, and is characterized in that the plastic bottom plate is 600mm long and 600mm wide and is internally provided with sheet iron; the cube plates are internally provided with magnets; and the side length of each cube plate is 100mm, and the four sides of each cube plate are provided with inclined planes of 45 degrees.
Description
Technical field
The utility model belongs to the teaching aid technical field, and specifically, the utility model relates to a kind of square planar development teaching aid.
Background technology
At present, in the teaching process to cube structure, the mode of normally drawing at blackboard by the use chalk; And the pattern expressive force on the blackboard is lower, is difficult to show very clearly to cubical structure; For the weak student of some spatial impression, the pattern on the blackboard is difficult to be understood.
And the teaching aid special of also not imparting knowledge to students for cube structure on the present market, this has brought inconvenience for cube structure teaching of teacher.
Summary of the invention
The utility model is exactly for the problems referred to above, provide a kind of simple in structure, easy to use, can allow the student fully understand the square planar development teaching aid of cube structure.
For reaching above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, and the utility model comprises a plastic bottom board and six plastics square plates, and it is characterized in that: the length of plastic bottom board is 600mm, wide is 600mm, is provided with iron plate in the plastic bottom board; Be provided with magnet in the described square plate; The square plate is that the length of side is the square plate of 100mm, and four limits of square plate are provided with the inclined-plane of 45° angle.
As a kind of preferred version of the present utility model, described backplate surface is fixedly installed four L shaped right angle poly (methyl methacrylate) plates, the square area that it is 101mm that four L shaped right angle poly (methyl methacrylate) plates surround a length of side.
The beneficial effects of the utility model: 1, simple in structure: the utility model only comprises a plastic bottom board, six square plates and four L shaped right angle poly (methyl methacrylate) plates, and its member is few, and is simple in structure.
2, easy to use: the utility model can be combined into a square by six square plates, and it is provided with the inclined-plane of 45° angle around the square plate, be convenient to the combination of square; Also the square plate development can be formed stretch-out view, by the magnet in the square plate and the iron plate in the plastic bottom board, the square plate is adsorbed on the plastic bottom board, be convenient to student viewing, easy to use.
And, the utility model is provided with four L shaped has a right angle machine glass plate, the square area that it is 101mm that four L shaped right angle poly (methyl methacrylate) plates surround a length of side can be positioned over the square that is combined into by the square plate in the square area, more is convenient to the stable of square.
3, displaying property is strong: this spatial structure as square of the utility model, and therefore, feel that intuitively displaying property is strong, is convenient to teacher's teaching can for the student.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is six cut-open views after the combination of square plate.
1 is that base plate, 2 is that iron plate, 3 is that right angle poly (methyl methacrylate) plate, 4 is that square plate, 5 is magnet in the accompanying drawing.
Embodiment
The utility model comprises a plastic bottom board 1 and six plastics square plates 4, and it is characterized in that: the length of plastic bottom board 1 is 600mm, and wide is 600mm, is provided with iron plate 2 in the plastic bottom board 1; Be provided with magnet 5 in the described square plate 4; Square plate 4 is the square plate of 100mm for the length of side, and four limits of square plate 4 are provided with the inclined-plane of 45° angle.
As a kind of preferred version of the present utility model, described base plate 1 surface is fixedly installed 3, four L shaped right angle poly (methyl methacrylate) plates 3 of four L shaped right angle poly (methyl methacrylate) plates square area that to surround a length of side be 101mm.
Above content is the further description of the utility model being done in conjunction with concrete preferred implementation; can not assert that implementation of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; can also make some simple deduction or replace, all should be considered as belonging to the definite protection domain of claims that the utility model is submitted to.
