| titleOfInvention | A kind of educational toy for children with feedback geometry |
| abstract | The invention discloses an educational toy for children with a feedback geometric body, which comprises a bottom plate and an upper box body, the top surface of the bottom plate is fixed with an upper box body, and the top plate of the upper box body is formed with a plurality of circular through holes, a plurality of A rectangular through hole and a plurality of triangular through holes, a cylindrical block is inserted into the circular through hole, a rectangular cylinder with a rectangular cross section is inserted into the rectangular through hole, and a triangular prism with a triangular cross section is inserted into the triangular through hole A plurality of elastic plates are fixed on the top surface of the bottom plate, a vertical sleeve body is fixed on the top surface of the elastic plate, and the corresponding rectangular cylinder, cylindrical block and triangular prism are inserted into the vertical sleeve body and pressed together against the top surface of the elastic plate. The present invention not only enables children to recognize the shapes of rectangles, triangles and circles, but also enables children to perceive different shapes when picking up the rectangular cylinders, cylinder blocks and triangular prisms placed in the upper box. Feel, meanwhile, when putting in rectangular cylinders, cylinder blocks and triangular prisms. |
