Description

Technical Field

[0001] The utility model relates to the technical field of magic cubes, in particular to a central body component of a maple leaf magic cube and a maple leaf magic cube. Background Art

[0002] The Maple Leaf Rubik's Cube usually includes a central body component, multiple corner blocks, multiple central blocks and multiple hidden edges. The central body component includes a spherical shell and multiple central axes. In the prior art, each central axis is an integrally formed one-piece, one end of each central axis is connected, and each central axis is connected to form a three-dimensional structure with each central axis protruding.

The central axes 2 of the central body assembly of the Maple Leaf Rubik's Cube of the present application are separated and are separate parts, and each central axis 2 is respectively arranged through the connecting groove 111 on the corresponding splicing shell 11. The central axes 2 of the central body assembly of the Maple Leaf Rubik's Cube of the present application can be produced separately, and the structure of the separate axis body is not easy to deform and cause cracks during use, and is not easy to break, has good quality stability, and has a long service life of the Rubik's Cube.

The corner block 3 includes a clamping plate 31, and one end of the center axis 2 located at the clamping block 22 passes through the interior of the corner block 3 and is connected to the clamping plate 31.
