Abstract
The utility model belongs to teaching instruments, particularly relating to a telescopic solid geometry magnetic learning bar. The learning bar comprises an outer sleeve (2) and an inner sleeve (1) positioned in the outer sleeve (2), wherein the outer sleeve (2) is a hollow rod with an opened end and a closed end; an iron sheet (3) is arranged inside the outer sleeve (2); the closed end of the outer sleeve (2) is provided with a magnet (4); both ends of the inner sleeve (1) are provided with magnets (4); the length of the iron sheet (3) is the same as that of the outer sleeve (2); and the magnets (4) are rectangular. The telescopic solid geometry magnetic learning bar has the advantages of simple structure, convenience and practicality and can be combined into various geometric models.
Description
Technical field
The utility model belongs to instruments used for education, particularly a kind of telescopic solid geometry magnetic study bar.
Background technology
On August 5th, 2009 disclosed application number a kind of solid geometry teaching mould that has been 200910044033.5 disclosure of the Invention; Process by tabular transparent material; It comprises four positive triangular pyramids in identical periphery and a positive tetrahedron; It is can be with the bottom surface of said four positive triangular pyramids in periphery overlapping fully and be combined into a cube to constitute each face of said positive tetrahedron; This teaching mould also comprises a transparent square outter box, and the cube that the size of this box body is combined into said four positive triangular pyramids in periphery and positive tetrahedron is just in time put into wherein.One in said four positive triangular pyramids in periphery is the combination triangular pyramid, and this combination triangular pyramid is made up of two identical tetrahedrons separably.This teaching mould also comprises four positive triangular pyramids of identical central authorities, and said positive tetrahedron is an inner box, and the size of this inner box can just in time be put into the central positive tetrahedron of the positive triangular pyramid combination of said four central authorities wherein.Though this practical new compact conformation can not be disassembled it, needs certain space to shelve, and when needs are used other model, must buy new model, can not effectively save resource.
The utility model content
The purpose of the utility model provides a kind of telescopic solid geometry magnetic study bar, and this study bar can make up easily and obtain various geometric figures.
The scheme that the utility model solve the technical problem is: a kind of telescopic solid geometry magnetic study bar; It comprises overcoat and the cover that is positioned at overcoat; Overcoat is the closed hollow stem of an end opening one end; The set inside iron plate of overcoat is provided with magnet on the closing end of overcoat, and the two ends of interior cover are provided with magnet.
This scheme is provided with overcoat and interior cover, makes the study bar become telescopic, its external sleeve with in put convenient combination of magnet and dismounting be set.The set inside iron plate of overcoat, in the magnet that puts can realize fixedly securing by iron plate.
As further technical scheme, the length of iron plate is identical with the length of overcoat.
The length of iron plate is identical with the length of overcoat, the length of convenient adjustment study bar.
As further technical scheme again, magnet is cuboid.
This scheme is arranged to cuboid with magnet, and magnet is better attracted each other.
In sum, the utlity model has simple in structure, convenient and practical advantage, can be combined into various geometric models.
