The object of the present invention is to provide a kind of making simple, be widely used, integrate mathematical operation function and magic square function, make uninteresting mathematical operation become interesting recreation, improve student's mathematical operational ability and flexible adaptability to changes effectively, be widely used in primary and secondary students' intelligence entertaining magic ball.

Technical solution of the present utility model is: by eight equal triangle ball clacks 1, six identical slick and sly sheets 3 and the magic balls that inner support 5 combines, inner support 5 is made by upper and lower, six orientation, front, rear, left and right and is interconnected six frame legs that intersect vertically, six identical slick and sly sheets 3 are connected with six frame leg tops of inner support 5, make six slick and sly sheets 3 on same sphere; Seven ball clacks are arranged with concentric with its similar interior ball clack 2 and be connected abreast in eight ball clacks 1, make to form slideway 6 between two ball clacks, be assembled between the ball clack by slick and sly sheet 3 and slideway 6 between ball clack 1 and the inner support 5 rotatable, the magic ball of slip.

Advantage of the present utility model is that it is better than " 24 recreation " of the U.S., it gathers multi-function in integral whole, flexible and changeable, only a ball just can change and 120 kinds of combination of numbers, be equivalent to change and 120 boards, get up be rich in interest so play, and playing method freely, can improve student's mathematical operational ability and flexible adaptability to changes effectively, the student is had great attractive force.

Following accompanying drawing has been described embodiment of the present utility model.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of ball clack of the present utility model;

Fig. 3 is the schematic surface of the utility model ball clack.

Below in conjunction with accompanying drawing the utility model is described in detail.Shown in Figure 1, by eight equal triangle ball clacks 1, six identical slick and sly sheets 3 and the magic ball that inner support 5 combines, inner support 5 is by last, down, before, after, a left side, right six orientation are made and are interconnected six frame legs that intersect vertically, six identical slick and sly sheets 3 are connected with the top of six frame legs, in the present embodiment, the central point that passes slick and sly sheet 3 with screw 4 is connected with the central point of frame leg, make each slick and sly sheet 3 on same sphere, seven ball clacks 1 in eight triangle ball clacks 1 are with concentric with its similar interior ball clack 2 and be connected abreast, make and form slideway 6 between two ball clacks, in the present embodiment, be to be shaped on double-deck boss 7 in the centre of ball clack 1, the centre of interior ball clack 2 is shaped on shrinkage pool, and the size of interior ball clack 2 is less than ball clack 1, the shrinkage pool of interior ball clack 2 is enclosed within on the double-deck boss 7 of ball clack 1, makes two ball clacks concentric and parallel, forms slideway 6(and sees Fig. 2).Interior ball clack 2 mainly is to establish for whole spheroid is shaped on slideway, also can adopt other version.Be assembled into magic ball by slick and sly sheet 3 and slideway 6 between ball clack 1 and the inner support 5, rotatable slip between the ball clack.There is a ball clack not establish interior ball clack for ease of installation in eight triangle ball clacks, holds limits fixedly to bond together for three of three slick and sly sheets corresponding in three angles of this ball clack and the spheroid with it.

Eight triangle ball clacks are the X by the centre of sphere, Y, the Z axle forms XY, XZ, three faces of YZ are cut apart ball and are obtained, three drift angles are arranged on each ball clack, on whole sphere, just form 24 such drift angles, and be in contact with one another 6 faces that are " ten " word between the formation drift angle, the position of 6 faces can form, down, before, after, a left side, right, that is to say, each " ten " literal 4 drift angles by 4 ball clacks are formed, on each " ten " are literal, be printed on 6 kinds of different colors, form 6 anchor rings, these 6 kinds of colors will be distinguished the spheroid true qualities, and be marked with 4 numerals between the 1-9 on 4 drift angles in each anchor ring, digital color can be identical with the spheroid true qualities, 24 numerals that are printed on altogether in 6 anchor rings that whole like this sphere just is made up of 6 kinds of colors and 6 anchor rings, 4 numerals in each anchor ring are a combination.The utility model adopts plastic injection-moulded forming, during making, go up (just that the numeric type system is good when making mould) one group of identical arabic numeral with annotating simultaneously separately on three angles of seven ball clacks in eight ball clacks, be respectively 1,2,3,4,5,8,9, for example three " 1 " words on three of first ball clack subscripts by that analogy, have three subscripts of a ball clack to get digital difference in eight ball clacks, annotate 6, one subscript 7(on two angle and see Fig. 3).

Because the utility model is taked said structure, making between the ball clack can rotational slide, continuous changed digital, combination of numbers on each anchor ring (or claiming the cross face) all changes thereupon like this, but no matter how combination of numbers changes, 4 numerals in each combination without exception, so can claim that again the utility model is " 4-24 " magic ball by adding, subtract, can get after multiplication and division and the extraction of square root computing the dual combination of " 4 " and " 24 ".During computing, each numeral in 4 numerals in each anchor ring can only be used once.In the utility model, 120 kinds of combination of numbers total inequality.During calculating, each group combination of numbers all must be made reflection in the time that limits, so can more effectively improve student's mathematical operational ability and flexible adaptability to changes.

Illustrate playing method of the present utility model.Example 1 is " 2349 " with the combination of numbers in the ball clack 2,3,4,8 together, is calculated as follows: 4 * 9 * 2 ÷ 3=24

2＋9－4－3＝4

Example 2 is " 3589 " with the combination of numbers in the ball clack 3,5,7,8 together, is calculated as follows:

3×9＋5－8＝24

（3＋9）÷（8－5）＝4

The utility model also has the function of magic square except that can carrying out interesting combination of numbers computing, after 6 identical spheres of color of ball are upset, can make it return to original position by intellection and conversion.

During the utility model assembling, make breach with three in the slick and sly sheet earlier, with screw 4 inner support 5 and six slick and sly sheets 3 are fixed together again.Then with 7 ball clacks 1 and interior ball clack 2 hot sticky are in the same place corresponding with it, and the slideway 6 that forms between should the bilayer ball clack is inserted among the notched slick and sly sheet 3 successively, and last single ball clack 1 is adhesive on the slick and sly sheet 3, promptly forms the spheroid of a sealing.
