Description

Technical Field

[0001] The invention relates to the technical field of magic cubes, in particular to a pyramid magic cube. Background Art

[0002] Since its inception, the Rubik's Cube has been popular all over the world because of its strong intellectual function for humans. The Rubik's Cube is easy to understand, ever-changing and flexible. To play it well, the player must be able to concentrate, think continuously, and not be impatient to gradually play it well. In a sense, the Rubik's Cube has become a special toy for intellectual development and a toy for testing the player's intelligence level and maturity, thus attracting a large number of players. Among them, the three-level Rubik's Cube is the most common. In order to enrich the playing methods of the Rubik's Cube, the pyramid Rubik's Cube was invented.

[0003] The existing Chinese invention patent with announcement number CN211752401U discloses a pyramid Rubik's Cube with adjustable magnetic force, including four corner block assemblies, four center block assemblies and six edge block assemblies, wherein the edge block assembly includes two edge block shells and two edge block shells are connected with connectors, and the slots of the edge block shells are installed with disc magnets; the center block assembly includes a center shell, three center block magnetic assemblies, a magnetic fixed sleeve and three center block cover plates. The magnetic force of the pyramid Rubik's Cube can be adjusted by adjusting the center block magnetic assembly. However, this method of adjusting the magnetic force requires adjusting each magnet, resulting in poor efficiency in adjusting the magnetic force, and it is difficult to ensure that the magnetic force exerted by each magnet is the same. It is necessary to adjust the magnetic force multiple times, which is relatively cumbersome, thus affecting the experience of playing the Rubik's Cube.

[0004] The Chinese invention patent with the announcement number CN204543510U discloses a new type of four-color tower Rubik's Cube, which includes a central axis, a corner assembly connected to the central axis, and a surface assembly arranged between the corner assemblies, wherein the corner assembly includes a small corner assembly, and a steel ball positioning adjustable device connected to the small corner assembly, and a small corner positioning device is provided at the connection between the small corner assembly and the steel ball positioning adjustable device. Although this Rubik's Cube is easier to do fault-tolerant movement, since there is no positioning mechanism, especially a magnetic positioning mechanism, in the Rubik's Cube, the positioning of the Rubik's Cube is inaccurate when the Rubik's Cube is rotated quickly, thus affecting the experience of playing the Rubik's Cube.

[0005] In order to prepare a pyramid Rubik's Cube that provides a better experience in playing with the Rubik's Cube, our company has invented a Rubik's Cube that not only performs fault-tolerant movements, but is also easy to position when turning the Rubik's Cube, and the positioning of the Rubik's Cube can be adjusted as needed, thereby optimizing the experience of playing with the Rubik's Cube.
