Abstract

The utility model provides a space formula changeable magic cube which is composed of cubes, and each face of the cube is composed of four squares. The utility model is characterized in that the contacting faces of the cubes are provided with three annular grooves which are mutually vertically crossed, the annular grooves use a center of the magic cube as the center of a circle and have the same diameter, and the inner part of each groove is provided with a circular arc-shaped rail and a movable separating block. The utility model not only has the simple change and the complicated change which are similar with the existing magic cube, but also has the medium difficult change that majority of persons can complete by effort, and thereby, more person can be interested in the magic cube.

Description

The modification magic square

The utility model relates to a kind of improvement of toy, particularly is used for the improvement of the magic square of riddle.

The profile of existing magic square is the cube formula, generally form by nine squares by each face of six kinds of colors, magic square, each square can move on the both direction in length and breadth with respect to other square, during recreation, by various variations the square conversion of each face different colours is restored and be solid color, this magic square is the Ceng Liuhang world since coming out.But the monochromatic recovery of the single face of this magic square is too simple, and the recovery more than two sides and the two sides is too complicated again, makes common people be difficult to grasp.

The purpose of this utility model just provides a kind of improved modification magic square, and this magic square also has the variation of the medium difficulty that majority also can finish through great efforts except simple change and complicated the variation are arranged, can make more people interested in the magic square.

The utility model is to realize like this, make a kind of modification magic square, form by eight cubic blocks, profile still is the cube formula, but cubical each face is made up of four squares, each square also can move on the both direction in length and breadth, can a kind of color on each facing, also can be pattern or numeral, principal character of the present utility model is: have three to be the center of circle with the magic square center on the contact-making surface between each cubic block, equal diameters, and the cannelure that intersects vertically mutually, arc-shaped rail and spacer block are movably arranged, in order to realize interconnecting and moving between cubic block and the cubic block in the groove.

Compare with existing product, the utility model has the advantages that: except monochromatic recovery of the single face that is easier to finish and difficult six the six looks recoveries of finishing are arranged, also difficult moderate, the two sides dichromatism that majority also can finish through great efforts restores and three three-colour displaies, and can finish in several ways, this just can make the interest of more people's increase to magic square.

Below in conjunction with accompanying drawing the utility model is elaborated:

Fig. 1 is the three-view diagram of a modification magic square, and wherein a figure is that the master looks schematic diagram, and b figure is a schematic top plan view, the position that A-A is analysed and observe, and c figure is that schematic diagram is looked on a left side.

Fig. 2 is the half section schematic diagram of modification magic square, and right-hand part A-A partly is a profile.(1) is cubic block among the figure, and each magic square has eight; (2) be arc groove, three arc grooves that radius is identical are arranged on each cubic block, its center of circle is the center of magic square; The all arc grooves of each magic square are formed three cannelures that intersect vertically mutually; (3) be spacer block, each magic square has six, when spacer block when groove moves to intersection with another groove, can turn to enter another groove; (4) be arc-shaped rail, each magic square has 12, and eight monoblock guide rails are wherein arranged, and four in a magic square, the monoblock guide rail is distributed in two cannelures by the bonding guide rail that forms of half block, and bonding guide rail is distributed in the 3rd cannelure.

Fig. 3 is the enlarged diagram of track cross-section, and vertical line among the figure (5) is a bonding wire, shows that this guide rail is by bonding the forming of two half block guide rails (6).

Fig. 4 is the stravismus enlarged diagram of spacer block;

Fig. 5 is the stravismus schematic diagram of modification magic square;

Embodiment:

The modification magic square should adopt the manufacturing of antifriction plastics, each modification magic square needs eight cubic blocks (1), six spacer blocks (3), eight monoblock guide rails (4) and eight half block guide rails (6), after these parts are made, be divided into two groups, four every group cubic blocks (1), four monoblock guide rails (4) and four half block guide rails (6); (3) one groups five of spacer blocks, one of another group, concrete assemble sequence is as follows:

1, every group of cubic block is combined into two half block magic squares respectively, has the face of arc groove (2) to combine cubic block (1) during combination, remaining face is placed on following with all around.

2, be respectively charged into corresponding spacer block (3) and guide rail (4) in the groove of half block magic square, spacer block (3) is contained in the intersection of groove and groove, and guide rail (4) is contained in the groove, and half block guide rail (6) is contained in the cannelure that combines with other half magic square.

3, after spacer block of two half block magic squares (3) and guide rail (4) all install, the half block guide rail (6) on its faying face is linked together with glue or alternate manner, make to form a complete modification magic square.

Claims (2)

1, a kind of modification magic square of the cube formula of being made up of cubic block (1) is characterized in that on the contact-making surface between each cubic block (1), has three to be the center of circle, equal diameters and the cannelure that intersects vertically mutually with the magic square center.

2, modification magic square according to claim 1 is characterized in that having the guide rail (4) of circular arc and spacer block (3) movably in cannelure.
