There is many weak points in current magic square on the market, as common magic square during fabrication, manufacturing cost is high, production efficiency is low, and be rudimentary magic square substantially at present, the requirement of the training of modern people's intelligence can not be met, between the limit block of existing magic square, combination has certain limitation, playability is not high, during rotation, the limit block of each centre can not rotate by adjacent two the limit blocks in face therewith simultaneously, makes magic square occur card when rotated, therefore, for the problems referred to above, a kind of regular dodecahedron magic square is proposed.

Utility model content

Have problems for above-mentioned prior art, the utility model provides a kind of regular dodecahedron magic square, and it is smooth that it has rotation, and production efficiency is high, low cost of manufacture, and advantage of waiting so long service life, solves Problems existing in background technology.

For achieving the above object, the technical solution adopted in the utility model is: a kind of regular dodecahedron magic square, comprises central block, limit block, hornblock, rotating shaft, groove, chute and convex key; Described central block is arranged on rotating shaft end, and is fixed by screw between central block and rotating shaft; Described central block sidewall arranges groove, and central block sidewall engaging limit block; Between described central block and limit block, hornblock is set, and hornblock sidewall arranges convex key; Be connected by chute between described hornblock with limit block, and hornblock, limit block and central block rotate around rotating shaft; Between described rotating shaft, angle is 120 °; Described central block rotates 180 ° around rotating shaft.

Further, described central block is the central block of regular pentagon structure.

Further, described hornblock to be a kind of cross section be diamond structure hornblock and with central block compact siro spinning technology.

Further, the cross section of described limit block is isosceles trapezoidal structure, and limit block and hornblock, central block are connected.

The beneficial effects of the utility model are:

1, compact conformation, service life is of a specified duration;

2, this kind of magic square has the spatial thinking ability of tempering people, sets up coordinate system, is very helpful to mathematics;

3, temper memory capability and reagency, rotate and there will not be Caton phenomenon, low cost of manufacture, have good economic benefit and social benefit, be applicable to promoting the use of.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of regular dodecahedron magic square, comprises central block 1, limit block 2, hornblock 3, rotating shaft 4, groove 5, chute 31 and convex key 32; Described central block 1 is arranged on rotating shaft 4 end, and is fixed by screw between central block 1 and rotating shaft 4; Described central block 1 sidewall arranges groove 5, and central block 1 sidewall engaging limit block 2; Between described central block 1 and limit block 2, hornblock 3 is set, and hornblock 3 sidewall arranges convex key 32; Described hornblock 3 is connected by chute 31 with between limit block 2, and hornblock 3, limit block 2 rotate around rotating shaft 4 with central block 1.

As optimisation technique scheme of the present utility model: between described rotating shaft 4, angle is 120 °; Described central block 1 rotates 180 ° around rotating shaft 4; Described central block 1 is the central block 1 of regular pentagon structure; The hornblock 3 of described hornblock 3 to be a kind of cross section be diamond structure and with central block 1 compact siro spinning technology; The cross section of described limit block 2 is isosceles trapezoidal structure, and limit block 2 and hornblock 3, central block 1 are connected.

The utility model in use, this magic square only has hornblock and limit block two slide block compositions, wherein hornblock is provided with chute, the face that limit block is connected with hornblock is provided with convex key, limit block is provided with chute on hollow each, convex key on the block of limit is established in supercentral chute, thus and thus, all limit blocks are connected according to the method with hornblock, during magic square is hand held, rotate to corresponding plane, rib block is moved on this plane, thus be reassembled into new plane with each face, make each upper all rib block color identical.

To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
