The specific embodiment

Embodiment one:

Present embodiment is described to be a kind of magic ball, and structure as shown in Figure 1.Described magic ball comprises: differ eight ball clacks 2 that 90 ° warp and equatorial line mark off the surface of ball through two of spheroid.Perhaps be described as: the spheroid in coordinate system separates eight ball clacks, ball clack of each octant in eight octants of coordinate system by X, Y, three planes of Z.Each ball clack is the eighth ball face, and an equilateral spherical triangle is formed on three circular arc limits of this eighth ball face, and each angle of this equilateral triangle is 90 °.These eight ball clacks can link together, and can move along warp and equatorial line mutually, are provided with the chute 21 as guide rail on each circular arc limit of ball clack.Fig. 2 is the front view of ball clack, because be orthographic drawing, so three circular arc limits of spherical trigonometry have only a circular arc type that reflects on figure, what two other reflected in the drawings is linear pattern.Article two, differ on 90 ° warp and the equatorial line every line the connection straps 1 of four approximate 1/4th spherical arcs are arranged.Fig. 3 is the front view of connection strap, and Fig. 4 is the side view of connection strap.As shown in the figure: connection strap is provided with the track convex ridge 11 that matches with ball clack upper rail chute along both sides, circular arc limit, and two convex ridges are arranged on every connection strap.In the guide rail chute that is inserted in ball clack that convex ridge on the connection strap can be very suitable, and can very slide therein freely.Because two convex ridges are arranged, the guide rail chute on the edge strip of convex ridge and a ball clack is connected, and another convex ridge is connected with the guide rail chute of another one ball clack upper sid strip, and the ball clack edge strip that connection strap is just adjacent with two lobes like this is slidingly connected together.This connector of connection strap be hidden in the ball clack surface below, do not see the existence that connection strap is arranged in shape.Present embodiment has 12 such connection straps, is provided with cross-coupled device 3 on the top that each linking bar connects from beginning to end.This cross connection device is very important, and it can make ball clack at the mutual convex ridge that enters into next connection strap when mobile accurately.If do not have this cross connection device when mobile ball clack must with the slit between each ball clack and the connection strap to very accurate, certainly will increase and rotate ball clack, reduce the enjoyment of playing magic ball.

Embodiment two:

Present embodiment is the improvement of embodiment one, is the improvement of the shape of the guide rail convex ridge on the cross section of the guide rail chute on the ball clack circular arc limit of embodiment one described magic ball and the connection strap that is mated.The cross section that each circular arc limit of described ball clack is provided with as the chute of guide rail is square step, and the guide rail convex ridge on the described connection strap is square step, as shown in Figure 5.

Embodiment three:

Present embodiment is the improvement of embodiment one, is the improvement of the shape of the guide rail convex ridge on the cross section of the guide rail chute on the ball clack circular arc limit of embodiment one described magic ball and the connection strap that is mated.The cross section that each circular arc limit of described ball clack is provided with as the chute of guide rail is a dove-tail form, and the guide rail convex ridge on the described connection strap is a dove-tail form, as shown in Figure 6.

Embodiment four:

Present embodiment is that the cross connection device of embodiment two, three described magic balls improves.The effect of cross connection device is to make each ball clack of magic ball more smooth and easy when relatively moving, so be smooth surface to the requirement of this jockey, is easy to roll, and can not hinder the relative motion of connection strap and ball clack.Cross connection device can be foursquare or regular polygon, and best is spheroid.Because spheroid meets above-mentioned requirements most.The described cross-coupled device of present embodiment is a spheroid.

Embodiment five:

Present embodiment is the above-mentioned improvement of respectively implementing described magic ball.It is the improvement of the ball clack in the described magic ball of the various embodiments described above.For ease of the assembling the various embodiments described above, can adopt several different methods.For example: on a ball clack transportable chute and elastic device are set, perhaps chute itself is made of elastomeric material exactly, can directly utilize its elasticity to install, and is similar to the mounting means of magic square.The elasticity installation method that present embodiment does not adopt common magic square to adopt, but by a special structure.In the present embodiment, form by the framework 4 of the equal spherical trigonometry in three limits by a ball clack in eight ball clacks.On the framework of spherical trigonometry, be pasted with a slice sphere 5, form a complete ball clack identical, as shown in Figure 7 with other ball clack profiles.The middle part on each limit of three frames of spherical trigonometry is provided with positioner, and this positioner is fixed together three frames of spherical trigonometry with three relative connection straps of periphery.The positioner that uses in the present embodiment is columniform alignment pin 6, as shown in Figure 8.There is dowel hole middle part at three frames of spherical trigonometry, on the relevant position of three connection straps relative locating hole is arranged also with three frames of spherical trigonometry, three alignment pins pass the locating hole that locating hole on three frames of spherical trigonometry and a connection strap use respectively, and three frames of spherical trigonometry are fixed together with three connection straps respectively.Three frames of spherical trigonometry are fixed together the effect that can also play the position of determining all connection straps with three connection straps respectively.If all connection straps all do not have to fix with ball clack, will make connection strap in the guide rail chute, slide into the optional position, the spheroid of cross connection device just may make the rotation generation obstacle of spheroid not in the position that crosses on four connection strap tops.

The installation method of present embodiment is: at first four ball clacks are coupled together by the guide rail chute on the individual ball clack with three connection straps, put into the cross connection device of a ball-shape on the top that three connection straps cross, insert the 4th connection strap afterwards again.Then other four connection straps are inserted in the guide rail chute on the hemisphere face that has formed half sphere, there is dowel hole the middle part of one of them connection strap, and the cross connection device with four ball-types after connection strap inserts is placed on the position that four connection strap tops cross.Utilize the guide rail chute on the ball clack edge strip to insert on the established hemisphere by order successively remaining three lobe ball clacks afterwards, and in the chute of these three ball clacks, insert four connection straps, wherein two connection straps link together three ball clacks, and half of two connection straps is empty in addition.There is locating hole middle part on these two half empty connection straps.Put into a cross connection device on the top of four connection straps, at this moment basically formed a sphere, but also lack a ball clack.At this moment the framework of spherical triangle is put into the position of last ball clack, the dowel hole on each limit of spherical trigonometry framework aligns with the dowel hole on the connection strap, inserts alignment pin afterwards in each dowel hole, as shown in Figure 8.At last a lobe sphere is covered the framework of spherical trigonometry, form complete spherical, install and finish.
