Description

Technical Field

[0001] This utility model relates to the field of toys, and in particular to a track mechanism and a Rubik's Cube. Background Technology

[0002] A Rubik's Cube typically consists of a center body assembly, multiple corner pieces, and multiple center pieces. The center body assembly includes a spherical shell and multiple central axes. In existing technology, each central axis is a single, integrally molded part, with one end of each axis fixedly connected to the others, forming a three-dimensional structure with protruding central axes. Since all components of the center body assembly are plastic parts manufactured using injection molding, the long central axes are highly susceptible to cracking, deformation, or even breakage during use, thus affecting the lifespan of the Rubik's Cube. Summary of the Invention

[0003] Therefore, it is necessary to provide a track mechanism and Rubik's Cube with a more stable structure and a longer service life.

[0004] This utility model provides a track mechanism, including a central sphere and track components. The surface of the central sphere is fixedly provided with eight connecting portions. Four of the connecting portions are evenly distributed along a first circumference of the central sphere, and the other four are evenly distributed along a second circumference of the central sphere. The plane containing the first circumference and the plane containing the second circumference are perpendicular to each other. The first circumference and the second circumference intersect to form a first intersection point and a second intersection point. The four connecting portions surrounding the first intersection point are equidistant from the first intersection point, and the four connecting portions surrounding the second intersection point are also equidistant from the second intersection point.

[0005] Eight track components are provided, and each track component is fixedly connected to one of the connecting parts;

[0006] The track component includes a spherical triangular plate and a fixing part. The fixing part is fixedly connected to the inner middle position of the spherical triangular plate. The fixing part and the connecting part are fixedly connected. The spherical triangular plate and the central sphere are spaced apart by a preset distance, and adjacent track components are also spaced apart by a preset distance.

[0007] Preferably, the central sphere comprises two hemispheres, namely a first hemisphere and a second hemisphere, which are fixedly connected.

[0008] Preferably, the first hemisphere is provided with a reinforcing plate and a connecting post, and the second hemisphere is provided with a reinforcing plate and a connecting hole, with the connecting post inserted into the connecting hole.

[0009] Preferably, a boss is formed on the inner edge of the first hemisphere and a recess is formed on the inner edge of the second hemisphere. After the first hemisphere and the second hemisphere are fixed, the boss is engaged with the recess.

[0010] Preferably, the reinforcing plate includes a first reinforcing plate and a second reinforcing plate, which are fixed together in a cross shape, and the hemisphere, the first reinforcing plate, and the second reinforcing plate are integrally formed.

[0011] Preferably, a central shaft is formed at the connection between the first reinforcing plate and the second reinforcing plate. A fixing screw hole is provided on the first central shaft of the first hemisphere, and a connecting groove and a connecting hole are provided on the second central shaft of the second hemisphere. The first central shaft is inserted into the connecting groove, and a screw passes through the fixing screw hole and is fixedly connected to the fixing screw hole.

[0012] Preferably, the first hemisphere and the second hemisphere are separated along the first circumference, and each of the connecting portions distributed along the first circumference is also divided into two parts, with the ends of the first reinforcing plate and the second reinforcing plate respectively close to one of the connecting portions.

[0013] Preferably, the spherical triangular plate is provided with mounting notches, and the mounting notches of every two adjacent spherical triangular plates are arranged opposite each other, and all the mounting notches are equidistant from the third circumference.

A retaining member is fixedly connected to each corner of the spherical triangular end face, and the retaining member is retainingly connected to the spherical triangular plate.

[0015] Preferably, the Rubik's Cube has eight pieces, which together form a sphere or a cube.

[0016] The track mechanism of this utility model includes a central sphere and a track component. The central sphere is fixed on the track component, and the Rubik's Cube pieces are connected to the track component. Compared with the Rubik's Cube of the prior art, this utility model does not have a long central axis, which greatly reduces the probability of Rubik's Cube damage and extends its service life.

[0017] The central sphere is set into two hemispheres to facilitate injection molding from the model.

[0018] Reinforcing plates are installed inside the first and second hemispheres to increase their strength and reduce the probability of damage; connecting columns, connecting holes, bosses, and recesses are installed to make the connection between the first and second hemispheres tighter and the structure more stable.
