Abstract

The utility model discloses a high fault-tolerance and high smoothness third-order magic cube which comprises six center cubes, eight corner cubes, twelve edge cubes, six center cube covers and a central shaft hidden in the dead center of the inner part of the Rubik's cube; six shaft ends perpendicular to one another are arranged on the central shaft; the center cubes are fixed at the shaft ends of the central shaft respectively; each center cube is provided with four rotary track arcs; each edge cube is provided with two rotary track arcs; three sunken chamfer angles are arranged on the inner side edge of each corner cube; four sunken chamfer angles are arranged on each edge cube; and the rotary track arcs of the center cube and those of the edge cubes form rotary track rings with the diameters smaller than 38 mm. Due to the sunken chamfer angles on the inner side edges of the corner cubes and those on the edge cubes, the fault tolerance performance of the Rubik's cube is improved during rotating; the diameters of the rotary track rings formed by the rotary track arcs of the center cube and those of the edge cubes are smaller than that of a traditional magic cube, so that the rotation resistance force of the Rubik's cube is reduced, further, fast rotation of the Rubik's cube can be performed advantageously.

Description

High fault-tolerant height is along three sliding rank magic squares

[technical field]

The utility model relates to a kind of toy, and relating in particular to a kind of high fault-tolerant height can three stubborn rank magic square of speed along sliding.

[background technology]

The three rank magic squares that belong to one of intelligence development type toy also claim Shandong Bick square, and his effect not only is to strengthen the instrument of user's spatial thinking ability, can also keep user's physical and mental health to a certain extent.General magic square mostly is six squares that a limber duroplasts is made, and three rank magic squares are made up of 26 squares in appearance, and 6 middle pieces, 8 hornblocks, 12 rib pieces are wherein arranged, and central shaft is hidden in the inner positive center of magic square.But the swing-around trajectory circle of three common rank magic squares is bigger, falls apart easily when the big high speed of the frictional resistance that magic square produces is rotated; Three common rank magic square fault freedoms are relatively poor, this cunning that has some setbacks of easy cacaine during rotation.

[utility model content]

At above defective, the purpose of this utility model provides a kind of rational in infrastructure, cheap, high fault-tolerant height that applicability is strong can speed twists along sliding three rank magic squares, thereby also is convenient to be extensive use of when improving magic square fan interest.

For achieving the above object, the utility model is by the following technical solutions:

A kind of three rank magic squares, comprise 6 middle pieces, 8 hornblocks, 12 rib pieces, 6 middle piece lids and be hidden in inner RC 1 central shaft of magic square, six orthogonal axle heads are arranged on the central shaft, each central shaft axle head is fixed a middle piece, piece is provided with 4 swing-around trajectory arcs in described, described rib piece is provided with two swing-around trajectory arcs, incline is provided with three chamferings of caving in the described hornblock, described rib piece is provided with four chamferings of caving in, the diameter of the swing-around trajectory circle that piece swing-around trajectory arc and rib piece swing-around trajectory arc form in described is less than 38mm, described rib piece is provided with one two to card base, described rib piece by described two to the card base inlay card between the room of two middle pieces, described hornblock is provided with a three-dimensional card base, and described hornblock is arranged between the room of three rib pieces by described three-dimensional card base.

As further improvement, described middle piece swing-around trajectory arc and rib piece swing-around trajectory arc form the swing-around trajectory circle that diameter is 26mm.

As further improvement, the axle head of described central shaft is provided with screw, fixes a middle piece by screw rod and spring.

The beneficial effects of the utility model: the fault freedom when the favourable magic square of the chamfering of caving in, the chamfering of caving on the rib piece in the hornblock on the incline rotates, the swing-around trajectory circle diameter that the swing-around trajectory arc of middle piece and the swing-around trajectory arc of rib piece form is littler than traditional Rubik three rank magic squares, reduced the resistance of magic square rotation, favourable speed is twisted, and this structure also can be used on the above high-order magic square in 4 rank.

[specific embodiment]

As depicted in figs. 1 and 2, a kind of three rank magic squares, comprise 1,6 middle piece lids 7 of 2,12 rib pieces of 4,8 hornblocks of 6 middle pieces and be hidden in inner RC 1 central shaft 5 of magic square, six orthogonal axle heads are arranged on the central shaft 5, each central shaft axle head is provided with screw, fixes a middle piece 4 by screw rod and spring.As shown in Figure 6, middle piece is provided with 4 swing-around trajectory arcs 12, the rib piece is provided with two swing-around trajectory arcs 11, incline is provided with three chamferings 3 of caving in the hornblock, the rib piece is provided with four chamferings 6 of caving in, the swing-around trajectory arc 12 of middle piece and the swing-around trajectory arc of rib piece 11 form the swing-around trajectory circle 8 that diameter is 26mm, the rib piece is provided with one two to rib piece card base 10, the rib piece by described two to the card base inlay card between the room of two middle pieces, hornblock is provided with a three-dimensional hornblock card base 9, and hornblock is arranged between the room of three rib pieces by described three-dimensional card base.

The swing-around trajectory circle 8 that the swing-around trajectory arc 11 of the swing-around trajectory arc 12 of piece and rib piece forms in described is that the swing-around trajectory circle of three rank magic squares of 38mm is little than traditional diameter, therefore the resistance in the time of can reducing to rotate, more laborsaving when making the magic square rotation, also reduce the probability of falling apart when magic square speed is twisted simultaneously.

Incline is provided with three chamferings of caving in the described hornblock, and multiple apparent form is arranged, and shows as Fig. 7 to Fig. 9.Described rib piece is provided with four chamferings of caving in, and multiple apparent form is arranged, and is extremely shown in Figure 5 as Fig. 3.Fault freedom when the favourable magic square of the chamfering of caving in, the chamfering of caving on the rib piece in the hornblock on the incline rotates, the swing-around trajectory circle diameter that the swing-around trajectory arc of middle piece and the swing-around trajectory arc of rib piece form is littler than traditional magic square, reduced the resistance of magic square rotation, favourable speed is twisted, and the chamfer design structure of caving in of this hornblock and rib piece also can be used on the above high-order magic square in 4 rank.

Except that present embodiment, the swing-around trajectory circle 8 that the swing-around trajectory arc 11 of the swing-around trajectory arc 12 of piece and rib piece forms in described, as long as its swing-around trajectory circle than traditional Rubik three rank magic squares is little, can reach effect of the present utility model, the swing-around trajectory circle 8 of existing traditional Rubik three rank magic squares is generally 38mm, and therefore swing-around trajectory circle of the present utility model can change in the scope less than 38mm.

The advantage that more than shows and described principal character of the present utility model and had.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the utility model also has some variations and improves under the prerequisite that does not break away from the utility model purport and scope, and these changes and improvements all fall in claimed the utility model scope.
