Abstract
The utility model provides a solid geometry model demonstration teaching aid, which comprises connection heads and connection rods, wherein two heads of each connection rod are assembled with the connection heads, each connection head is in a step shape, the outward end is in a cone shape, the connection head is a multi-directional mobile connection head, the connection rods have arc-shaped and straight line-shaped two kinds, the plurality of multi-directional mobile connection heads and the plurality of connection rods can be combined to form the solid geometry model demonstration teaching aid, and the connection rods are either hollow or solid. The solid geometry model demonstration teaching aid is simple in structure, convenient in operation, and is vivid and intuitive, and the solid geometry model demonstration teaching aid can be quickly assembled into cone, cylinder, sphere and other rotating solid geometry models, and can be conveniently and quickly assembled into a needed solid geometry model in the teaching process.
Description
Technical field
The utility model relates to a kind of teaching aid, especially a kind of solid geometric pattern demonstration teaching aid capable of being combined.
Background technology
Teaching aid used in existing solid geometry teaching, it is all the stereoscopic model that is assemblied by unidirectional or Multidirectional connector, connecting link, but this combination solid geometric pattern, can only be assembled into polyhedron, and for rotary body, just can't assemble with general straight connecting rod, therefore the version of combination is restricted.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art and provides a kind of simple and reasonable, easily assembling, and can be assembled into the model demonstration teaching aid of the rotary bodies such as cone in solid geometry, right cylinder, spheroid.
In order to solve the problems of the technologies described above, the utility model comprises connector and connecting link, assemble mutually with connector at connecting link two, connector is stepped, an outside end becomes taper, described connector is multidirectional flexible connection head, and described connecting link has two kinds of arc and linears, and a plurality of multidirectional flexible connections heads can constitute the solid geometric pattern demonstration teaching aid mutually with a plurality of connecting links.
Described connecting link is hollow or solid.
The utility model is simple in structure, and is easy to operate, and can be assembled into fast the rotary stereo geometric models such as spheroid, right cylinder, lively directly perceived, can be assembled into easily and fast required solid geometric pattern in teaching process.Therefore not only intuitive is strong for the utility model, and teaching efficiency is good.
Description of drawings
Fig. 1 is the cone schematic diagram in the rotary body solid geometric pattern.
In figure: 1, multidirectional flexible connection head; 2, connecting link; 3, cone.
Embodiment
As shown in Figure 1, the utility model comprises connector and connecting link 2, assemble mutually with connector at connecting link 2 two, connector is stepped, an outside end becomes taper, described connector is multidirectional flexible connection 1, and described connecting link 2 has two kinds of arc and linears, and a plurality of multidirectional flexible connections 1 can constitute the solid geometric pattern demonstration teaching aid mutually with a plurality of connecting links 2.Described connecting link 2 is hollow or solid.The utility model is simple in structure, and is easy to operate, and can be assembled into fast the rotary stereo geometric models such as cone 3, right cylinder, spheroid, lively directly perceived, can be assembled into easily and fast required solid geometric pattern in teaching process.
The above is only preferred embodiment of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; in every case the equivalence done according to the utility model institute disclosure of those of ordinary skills is modified or changes, and all should include in the protection domain of putting down in writing in claims.
