Description

Technical Field

[0001] The utility model relates to the technical field of Rubik's cubes, and particularly relates to a ball shaft and a Rubik's cube. Background Art

[0002] The central structure of an existing Rubik's cube has a central body and a shell assembly. There are multiple shaft bodies on the central body, and multiple through holes on the shell assembly. The shell assembly is sleeved on the shaft bodies through the through holes. Multiple magnets are arranged on the inner wall of the shell assembly, and magnets are also arranged on each corner block of the Rubik's cube. The magnets on the shell assembly are adsorbed to the magnets on the corner blocks, which can assist the Rubik's cube to return to its position when it is about to be rotated into a cube. After returning to its position, the magnets are attracted to each other to lock with a certain force so that the Rubik's cube is not easily deformed.

[0003] However, there is no limiting and matching structure between the shaft body of this kind of Rubik's cube and the through holes of the shell assembly. After the shell assembly and the central body are assembled, there is an assembly gap between the two, and the shell assembly and the central body may move relative to each other, affecting the installation accuracy of the shell assembly, resulting in a certain deviation between the position of the magnet on the shell assembly and the target position, causing inaccurate alignment of the relative positions of the magnet on the shell assembly and the magnet on the corner block, and affecting the performance of the Rubik's cube.

[0004] In order to overcome this deficiency, the Chinese utility model patent with the publication number of CN 220309720 U discloses a central structure of a Rubik's cube and a Rubik's cube. The central structure includes: a central body, a shell assembly and several first magnetic components. The central body has a shaft body, and the shaft body has an annular card slot. The shell assembly has a through hole, and the shell assembly is sleeved on the shaft body through the through hole, and the shell assembly is clamped in the annular card slot. The first magnetic components are arranged on the shell assembly. The central structure of the Rubik's cube in this application sets an annular card slot on the shaft body. The shell assembly is clamped in the annular card slot through the through hole and the shaft body, so that the shell assembly and the central body are limited and fixed after assembly. The shaft body and the through hole are tightly matched, and the shell assembly and the central body will not move relative to each other, making the installation position of the shell assembly accurate. Furthermore, the installation position of the first magnetic component on the shell assembly is accurate, and the first magnetic component on the shell assembly and the magnet on the corner block are accurately aligned, improving the performance of the Rubik's cube. Although the technical solution provided by this patent can partially solve the problem of inaccurate alignment of the relative positions of the magnet on the shell assembly and the magnet on the corner block, the first magnetic component of the above central structure is arranged in the installation groove of the shell assembly. Due to the limited structure of the shell assembly, the setting position and distribution mode of the installation groove on the shell assembly are relatively fixed and single. Therefore, there are technical problems of inaccurate coaxiality and end face parallelism between the first magnetic components on the ball shaft, and there is also a problem of inaccurate alignment distance between the first magnetic component on the ball shaft and the second magnetic component on the corner block, affecting the performance of the Rubik's cube.
