Crank connecting rod type building blocks

Abstract

The invention discloses a crank-and-link type component piece educational building block, which comprises several polygonal geometric plate-shaped component pieces, and the several component pieces are fastened and connected by connectors to form a planar or three-dimensional geometric building block model, wherein , containing at least one driving eccentric gear and driven eccentric gear, said eccentric gear is provided with at least one eccentric hole; the pitch circle diameters of the driving eccentric gear and driven eccentric gear are equal, and an elastic connecting shaft is arranged in the center thereof, and the moving The matching shaft is set in the preset perforation on the component sheet; in addition, at least one connecting rod is included, and a connecting rod shaft is provided at both ends of the connecting rod, and the connecting rod shaft is movably fitted through the driving eccentric gear and the driven eccentric gear In the eccentric hole on the top, the crank connecting rod transmission mechanism is formed. The invention stimulates children's interest in learning popular science knowledge through the combination of various interesting dynamic building blocks, so that children can learn physics, geometry, mechanical transmission and mechanics knowledge in a happy way, thereby achieving the purpose of entertaining and teaching.

Description

technical field [0001] The invention belongs to the field of toys, and relates to a building block toy with component pieces combined, in particular to a crank-link type component piece educational building block with mechanical transmission effect. Background technique [0002] As we all know, toys are extremely important products for children's intelligence inspiration, and they are teachers for children's early intelligence development. good effect. [0003] Geometric component piece building blocks are a typical variety in the field of building block toys. At present, most of the traditional geometric component piece building blocks in the market use connecting rods to realize combined connection, that is, a pair of concave spherical blocks are arranged at both ends of the connecting rod. The fastening part is provided with a concave connection part on each side of the geometric component sheet, and a convex spherical fastening part is respectively provided at the two o...

Problems solved by technology

[0005] However, the various geometric models combined by the above-mentioned geometric component piece building blocks are all static models. They do not have any mechanical transmission structure and cannot produce any dynamic effects. Inconsistencies, such as operating a static building block toy for a long time, will make children feel boring, lose patience and curiosity, and lose their appeal to children

[0006] Although the geometric component piece building blocks of some improved varieties have increased common gear attachments, they can only be used as modeling decoration of the geometric component piece building block model and simple transmission between plane gears. Therefore, such existing technical products It still seems monotonous and boring, and cannot satisfy children's curiosity and thirst for knowledge, thus failing to achieve the purpose of stimulating children's thinking ability and restricting children's creativity
