Description

Magic cube

Technical field

The invention relates to the technical field of toys, in particular to a magic cube.

Background technique

The magic cube toy first appeared in 1974. It was invented by Hungarian architecture professor and sculptor Erno Rubik. In recent years, it has been popularized in our country. The cube has even entered school classrooms. Its core structure is a cubic track mechanical structure. Nowadays, most of the improvements, upgrades and transformations of the Rubik’s Cube are difficult to break away from the cube track mechanical structure system. Its structure allows the cube to move only on a fixed track, so that the cube cannot be separated from the track and converted into a strip magic ruler or a chain magic ruler. Or cuboid or cube; the magic ruler was also invented by Erno Rubik. In recent years, the popularity of the magic ruler has also been very high, and it has also entered school classrooms; the magic ruler is connected by a connecting shaft to connect a triangular prism. Yes, the technical structure of the magic ruler is relatively simple. The connecting shaft passes through the center hole of the square faces of two adjacent triangular prisms, so that the two adjacent triangular prism squares are infinitely connected.

The prior art triangular prism magic ruler square has a total of 5 faces. Due to structural design limitations, the square surfaces of two adjacent triangular prism magic rulers that are parallel and coplanar cannot be vertically flipped and intersected, making the magic ruler stick unable to be transformed. Cube shape and some other natural shapes.

Summary of the invention

The invention aims to solve the defect that the existing magic ruler squares cannot be vertically flipped and intersected, so that the magic ruler stick cannot be transformed into a cube shape and some other natural shapes, and provides a reasonable structure, which can be flipped freely and can be transformed into a cube shape And some other natural-shaped magic squares.

In order to achieve the above objective, the present invention adopts the following technical solutions: a magic cube, including a plurality of cubes and connecting shaft components, the cube is a hollow body, and the cube is provided with a first moving rail groove and a second moving rail groove The first moving rail groove includes a connecting groove from the center of the left side of the cube to the center of the front side of the cube, and the second moving rail groove includes a connecting groove from the center of the right side of the cube to the center of the rear side of the cube, so The connecting shaft assembly includes a connecting spindle, a spring, and a movable ring.
