Abstract

The utility model provides a dodecahedral rotary magic ball, which comprises a central cube, twelve positioning axes and twelve groups of rotary bodies. Each group of the rotary bodies comprises a cubic block A, five cubic blocks B and five cubic blocks C, wherein, each cubic block B is shared by two adjacent groups of rotary bodies, and each cubic block C is shared by three adjacent groups of rotary bodies, the whole magic ball has twelve cubic blocks A, thirty cubic blocks B and twelve cubic blocks C in total. The magic ball of the utility model has the advantages that because the magic ball has twelve groups of rotary bodies which can independently rotate, the change is more peculiar, when the game is played, the intelligence is more required, and the intelligence of the human can also be inspired, thereby the magic ball has better knowledge and interest.

Description

The dodecahedron Rotary magic ball

Technical field

The utility model relates to a kind of puzzle, particularly a kind of dodecahedron Rotary magic ball.

Background technology

On market, various magic squares, magic stick, magic ball are vied with each other for glamour, and have greatly enriched the toy world of children, even also allow some adults always enjoy it.By moving back and forth magic square, magic stick or magic ball, intelligence that can exploit person is tempered people's finger flexibility, and is improved the color detection ability of eyes.The structure of magic square, magic stick or magic ball is formed, and has determined the difficulty of recreation, we can say that the absolute construction unit of forming magic square, magic stick or magic ball is many more, and the aspect that can independently rotate is many more, and the difficulty of recreation is just big more.

The utility model content

The purpose of this utility model is exactly in order to provide a kind of dodecahedron Rotary magic ball.

The technical solution of the utility model is: a kind of dodecahedron Rotary magic ball comprises:

A middle body-centred cube;

12 locating shafts on the body-centred cube and with cubical center, center are that the even distribution of the centre of sphere is outwards dispersed during it is connected to;

12 groups of rotary bodies, every group of rotary body comprises that an outer surface is the cubic block A of regular pentagon, five outer surfaces and is the cubic block C that trapezoidal cubic block B and five outer surfaces are prismatic, wherein each cubic block B is shared by the two adjacent groups rotary body, each cubic block C is shared by adjacent three groups of rotary bodies, whole magic ball has 12 cubic block A, 30 cubic block B and 20 cubic block C; The outer end that each cubic block A is positioned at the centre of respectively organizing rotary body and is movably connected in each locating shaft can rotate around locating shaft, each cubic block B fits with the limit of the limit of this group cubic block A and adjacent group cubic block A respectively and links to each other, and each cubic block C is separately positioned on five angles of cubic block A and links to each other with the two cubic block B of this group and each two cubic block B applying of two adjacent groups respectively; Each outer surface of organizing rotary body is regular pentagon, and inner surface is in the same plane parallel with outer surface and links to each other with the plane applying with the member of adjacent set rotary body.

The inner surface of described each cubic block A is a spherical cambered surface, and it is the interior spherical cambered surface of the centre of sphere with cubical center, center that the inner surface of 12 cubic block A forms one; The inboard of described cubic block B is provided with the fixture block that extends to the two cubic block A directions that connected, and this fixture block suits with the spherical cambered surface inner surface of corresponding cubic block A and links to each other; The inboard of described cubic block C is provided with the fixture block that extends to the three cubic block A directions that connected, and this fixture block suits with the spherical cambered surface inner surface of corresponding cubic block A and links to each other.

Body-centred cube is spheroid or dodecahedron in described.

Magic ball of the present utility model is owing to have 12 groups of rotary bodies that can independently rotate, and its variation is more marvellous, more needs intelligence during recreation, also more can excite people's intelligence, thereby have more intellectual and interest.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2, Fig. 3, dodecahedron Rotary magic ball of the present utility model comprises 1,12 locating shafts 2 of a middle body-centred cube and 12 groups of rotary bodies 3.In order to see internal structure clearly, the last figure among Fig. 1 has taken out one group of rotary body and has been placed on figure below.In addition, the locating shaft among the figure 2 does not all draw yet.

Middle body-centred cube 1 can be spheroid or dodecahedron, and present embodiment is depicted as dodecahedron.

On the body-centred cube 1 and with cubical center, center be that the even distribution of the centre of sphere is outwards dispersed during 12 locating shafts 2 are connected to.

Every group of 12 groups of rotary body comprises that an outer surface is the cubic block A of regular pentagon, five outer surfaces and is the cubic block C (seeing the figure below among Fig. 1) that trapezoidal cubic block B and five outer surfaces are prismatic, wherein each cubic block B is shared by the two adjacent groups rotary body, each cubic block C is shared by adjacent three groups of rotary bodies, whole magic ball has 12 cubic block A, 30 cubic block B and 20 cubic block C.

The outer end that each cubic block A is positioned at the centre of respectively organizing rotary body and is movably connected in each locating shaft can rotate around locating shaft, the inner surface of each cubic block A is spherical cambered surface, and it is the interior spherical cambered surface of the centre of sphere with cubical center, center that the inner surface of 12 cubic block A forms one.

Cooperation is referring to Fig. 4, each cubic block B links to each other with the limit of this group cubic block A and the limit applying of adjacent group cubic block A respectively, the inboard of cubic block B is provided with the fixture block B 1 that extends to the two cubic block A directions that connected, and this fixture block suits with the spherical cambered surface inner surface of corresponding cubic block A and links to each other.When rotating, this fixture block can slide onto the spherical cambered surface inner surface of two cubic block A of back along the spherical cambered surface inner surface of present two cubic block A, establishes the screens relation again.

Cooperation is referring to Fig. 5, and each cubic block C is separately positioned on five angles of cubic block A and fits with each two cubic block B of the two cubic block B of this group and two adjacent groups respectively and links to each other.The inboard of cubic block C is provided with the fixture block C1 that extends to the three cubic block A directions that connected, and this fixture block suits with the spherical cambered surface inner surface of corresponding cubic block A and links to each other.When rotating, this fixture block can slide onto the spherical cambered surface inner surface of three cubic block A of back from the spherical cambered surface inner surface of present three cubic block A, establishes the screens relation again.

Each outer surface of organizing rotary body is regular pentagon, and inner surface is in the same plane parallel with outer surface and links to each other with the plane applying with the member of adjacent set rotary body.When rotating, be exactly the slip between the plane like this, add the slip of each fixture block on cubic block A spherical cambered surface.
