Abstract

The invention provides a combined mechanical model, and belongs to the field of mechanical models. The combined mechanical model comprises a plurality of connecting bodies, a plurality of spline shaftsleeves and a plurality of connecting rod bodies, wherein the connecting bodies, the spline shaft sleeves and the connecting rod bodies are matched; each connecting body comprises a body piece, wherein the body piece is provided with spline holes, cross-shaped inserting holes and terminal grooves, the spline holes are evenly distributed in a cross-shaped mode with 10 as the modulus, the spline holes are formed in the rim of a round hole, and four cross-shaped cuboid key grooves are formed in the rim of the round hole at 90 degrees; the cross-shaped inserting holes are symmetrical cross-shapedinserting holes, and cross-shaped inserting heads of the cross-shaped inserting holes are symmetrical right cross-shaped inserting holes; and the terminal grooves are of a wedge-shaped structure andare of a dovetail structure. According to the combined mechanical model, various inserting modes can be obtained, inserting combination of the body pieces is greatly facilitated, and the combined mechanical model is more convenient to use, more flexible and easier to innovate and create.

Description

technical field [0001] The invention belongs to the field of mechanical models, and relates to a mechanical model of an assembled building block structure, in particular to a combined mechanical model. Background technique [0002] At present, combined physical teaching aids, learning aids, and toys are very popular educational tools in educational activities in developed countries. Similar products in my country generally imitate Lego's convex-circular-concave-square or shaft-hole combination insertion method. Most of them are based on building block combination structures, which belong to toy products. Intuitive and true reproduction of mechanical structure and working principle cannot well meet the needs of technological innovation education and professional teaching activities. I started research in this area in 2003, and obtained the invention patent of "Assembly Physical Teaching Aids" in 2004, and obtained the technical solution disclosed in the invention patent zl200...
