Abstract

The utility model belongs to the technical field of a toy which is similar to a magic cube. The utility model is in the shape of a regular tetrahedron. The center of the regular tetrahedron is provided with four supporting axles 1 with equal length, wherein, one of the four supporting axles has equal included angles with the other supporting axles; a regular octahedron block 3 is sheathed on the supporting axles 1, and can rotate around the axle centers of the supporting axles 1; the bottom of the regular octahedron block 3 is a triangular spherical surface with equal arc edges. A plurality of sockets are arranged on the top of the regular octahedron block 3; a regular tetrahedron block 5 is connected with the top of the supporting axles 1 in a clamp-insert mode, and can rotate around the supporting axles 1; the triangular spherical surface on the bottom of the regular octahedron block 3 is connected with a regular tetrahedron block 2 in a clamping mode. The magic triangle has the advantages of simple connection mode of inner structure, easy fabrication and machining, low cost, relative simple play rule, strong interest, etc.

Description

Magic triangle

The utility model relates to a kind of technical field of similar puzzle toy.

The mankind have invented toy for amusement, wherein magic square is as a kind of puzzle, liked by the masses, but those can finish it independently the people of those 4,300 hundred million hundred million kinds of corresponding unique correct combinations of combination, it is very little to say so, said ' we rotate magic square as magic square inventor Shandong Bick, magic square folding evil spirit we ', a kind of new toy Magic triangle abroad is provided, be positive tetrahedron, calculate according to mathematical theory, it is 2.5 * 10 that its combination falls sharply ⁷Kind, therefore corresponding difficulty has also reduced by 1.7 * 10 ¹²Times, be the capable fully a kind of puzzle that restores of ordinary person, but external this toy Magic triangle, its spill spin block is connected to screw and connects, and processes inconvenient shortcoming so its connection complexity causes.

The purpose of this utility model is to provide a kind of Magic triangle simple and easy, easy to process that connects.

The technical solution of the utility model is achieved in that this positive tetrahedron has at the center that a bolster equates with the angle of all the other bolsters, four bolsters of equal in length; Be with the regular octahedron piece of its bottom that can rotate around the bolster axle center for the equal triangle sphere in arc limit on bolster, regular octahedron piece top has some jacks; Connect a positive tetrahedron piece at the bolster top by blocking the mode of inserting, it can rotate around bolster; Connect a positive tetrahedron piece on regular octahedron piece bottom triangle spherical arc limit by snap fit.

Described bolster top and the positive tetrahedron piece card mode of inserting is connected to the bolster top and opens and be card base, and positive tetrahedron piece bottom has hole clipping; Pad is equipped with in described positive tetrahedron piece bottom, this pad has hole clipping, and the jack at corresponding regular octahedron piece top has pin, and the clamping of described regular octahedron piece bottom and positive tetrahedron piece is that the positive tetrahedron piece has two card bases that match with regular octahedron piece bottom triangle sphere on one side; The gore of described positive tetrahedron outer surface posts colored plastic sheet or colored pressure-sensitive adhesive labeling or directly prints various patterns.

Below in conjunction with description of drawings embodiment of the present utility model is further described.

Shown in Fig. 1-7, Magic triangle of the present utility model is the positive tetrahedron configuration, and its center has that angle equates, four bolsters (1) of equal in length, and it is two card bases that bolster (1) axle head is opened.On each bolster, be with the regular octahedron piece (3) of its bottom that to rotate around bolster (1) axle center for the equal triangle sphere in arc limit, regular octahedron piece (3) top has some jacks, pad (4) is equipped with in positive tetrahedron piece (5) bottom, and the jack at corresponding regular octahedron piece (3) top has pin, the corresponding bolster of pad (4) top card base correspondence has hole clipping, the bolster top connects a positive tetrahedron piece (5) by blocking the mode of inserting like this, it can rotate around bolster, positive tetrahedron piece (2) connects regular octahedron piece (3) by snap fit, have simultaneously two card bases that match with regular octahedron piece (3) bottom triangle sphere on positive tetrahedron piece (2) one side, regular octahedron piece bottom triangle sphere is connected positive tetrahedron piece (2) by three arc limits with the cassette mode like this.By just can be with upper type and be assembled into a positive tetrahedron Magic triangle by blocking method such as slotting merely without connector such as screw, post colored plastic sheet or colored pressure-sensitive adhesive labeling on its four outer surface gores or directly print various patterns, wait combination by the rotation rotation, making any one side of Magic triangle positive tetrahedron at last is that a kind of plain color is as red, yellow, blueness, green or complete pattern.

Advantages such as Magic triangle internal structure connected mode of the present utility model is easy, manufacturing handling ease, cost is low and playing method is simple relatively, interest is strong.
