How much teaching aids of assembly type space multistory; Comprise three groups of above linkage units and cooperates the connecting rod more than a group of grafting with linkage unit; Described linkage unit is: the grafting joint that in rotating shaft, is set with several band grafting positions; The location portability of grafting joint in rotating shaft is moving and rotatable; Described connecting rod is solid connecting rod or hollow connecting rod, and the end of connecting rod is provided with and cooperates the connecting portion of pegging graft with the grafting position of the joint of pegging graft, and every group of connecting rod has different length and every group of connecting rod is made up of the connecting rod more than the six roots of sensation.
Above-mentioned rotating shaft is torus or oval ring body or rectangle framework or C type body or T type body or L type body or cross body.
Above-mentioned torus or oval ring body are provided with the opening of flexible installation grafting joint.
The end of above-mentioned C type body or T type body or L type body or cross body is provided with spacing preiection or spacing hole, and spacing hole is provided with latch.
One end of above-mentioned grafting joint is provided with and is sleeved on the through hole in the rotating shaft or is provided with the C jacket that can be connected in the rotating shaft, and the other end is the right cylinder that solid cylinder or lateral surface are provided with blind hole.
Above-mentioned grafting joint has 5 at least.
Above-mentioned grafting joint has 6-12.
Above-mentioned linkage unit and connecting rod are made with plastic material.
The utility model is compared the outstanding and beneficial technical effects of prior art:
1, utilizes a plurality of multi-angle connecting bases of the utility model; By different solid geometry frameworks connecting rod on pegging graft on the grafting joint of multi-angle connecting base; Can form different solid geometry frameworks; Utilize this solid geometry framework to see at an easy rate solid geometry characteristic and the known conditions that will solve a problem and position or the angular relationship of being asked object, lively, image, directly perceived.
2, the utility model can be used as solid geometry teaching aid, also can be used as toy, from little cultivation people's solid geometry notion and space imagination.
