Abstract

The utility model relates to a magic regular trigon. The magic regular trigon is a centre rest which is intersected as integration by four support columns. The space angle is equally divided by the four support columns which are respectively provided with internal thread holes. The end of the column is connected with heart blocks. A single heart block is provided with a regular triangle outer surface, an inner ball arc surface and an awl plate of stepped piercing holes of the inner protruding column. An edge waist block is supported by the two heart blocks. The cross section of the single edge waist block is in diamond. The middle section of the angle edge is provided with a sphere block which can be rotated freely and is horizontally fastened in the inner ball arc surface of a heart block. One apical angle block is supported by the three edge waist blocks. The whole body of the single apical angle block is in hexahedral diamond. The apex angle block is provided with a sphere block which can be rotated freely and is horizontally fastened in the inner ball arc surface of a heart block. The magic regular trigon can exercise people's space thinking ability. The utility model has the advantages of strong spice, simple structure, novel model, and is suitable for both the young and the old.

Description

Magic triangle

The utility model relates to toy, especially a kind of Magic triangle.

At present people are for thinking skills training and the raising interest of playing, and being extensive use of has toys such as magic stick, magic square, and appearing on the market of it is very popular.Yet this T-toy has carry, play is convenient inadequately; Have exercise raising people spatial thinking ability is still needed further improves.

The purpose of this utility model is that a kind of improved Magic triangle will be provided, and it can temper the spatial thinking ability that improves people effectively, and is interesting strong.

The purpose of utility model is achieved in that four are divided equally the centre frame that pillar that Space Angle respectively makes the internal thread hole meets at one, and each post ends connects a heart piece.Single heart piece is shaped on the cone-plate of projection in equilateral triangle outerplanar, basic interior spherical cambered surface, the band ladder center hole.Per two heart interblocks support a limit waist piece, and waist piece cross section, single limit assumes diamond in shape substantially, and an arm of angle stage casing is shaped on to crouch and is stuck in the interior spherical cambered surface of two heart pieces and the basic sphere piece that can rotate.Drift angle piece of per three limit waist piece together support, single drift angle piece integral body is six rhombuses, and a drift angle is shaped on to crouch and is stuck in the interior spherical cambered surface of adjacent three heart pieces and the basic sphere piece that can rotate.

The outerplanar that device is whole, can be directly each of the same colour.It also can be the facial mask of or complete pattern sticking homochromy according to all branch in coplanar.

The advantage of utility model: can take exercise and improve people's spatial thinking ability; Interesting strong, all-ages; Simple in structure, modern design.

Below in conjunction with details and the working condition of Fig. 1～6 detailed descriptions according to the concrete device that the utility model proposes

This device comprises a centre frame 4, and it is provided with four pillars of dividing equally Space Angle and meeting at one (being that each axial line meets at a bit), each pillar system axial internal thread hole and equal in length.Post ends respectively connects a heart piece 3, and single heart piece is shaped on the equilateral triangle outerplanar, is the cone-plate of projection in the interior spherical cambered surface, band ladder center hole substantially.Here have two problems to illustrate: one is the problem that concerns of heart piece and centre frame post ends (portion), can be slightly long as the interior projection of center of fiqure piece, and ladder punching nose end increases the system active packet and receives the hole section of centre frame strut ends section.The interior projection that also can be heart piece is slightly short, and its end face is directly relative with centre frame pillar end face.Another problem is the post ends of centre frame and being connected of heart piece, can be to select for use tapping screw 5 to be added with plain cushion as figure, can be that plain cushion is used borded pile spring section instead, also can be direct connection, should ensure that heart piece can freely rotate, and connect lastingly.The interior spherical cambered surface of four heart pieces is positioned on the same movement locus ball face.Per two heart interblocks support a limit waist piece 2, amount to 6.The cross section of single limit waist piece assumes diamond in shape, and main looking is approximate trapezoid, and an arm of angle stage casing is shaped on to crouch and is stuck within the interior spherical cambered surface of adjacent two heart pieces, and can be along the basic sphere piece of said movement locus ball face rotation.Every drift angle piece 1 of adjacent three limit waist piece together support amounts to four.Single drift angle piece integral body is six rhombuses, and being shaped on the drift angle crouches is stuck in the interior spherical cambered surface of adjacent three heart pieces, and can be along the basic sphere piece of said movement locus ball face rotation.The centre frame of this device, heart piece, limit waist piece, drift angle piece etc. all adopt plastics to cast.

This device is whole to constitute four equilateral triangle outerplanars, can be directly each a kind of color.Also can be to divide sticking homochromy according to all outerplanar or belong to the facial mask 6 of a complete pattern in same outerplanar.

During use, setting each outerplanar is (or a kind of pattern) of the same colour.For an optional equilateral triangle outerplanar, an once rotatable limit (containing this outerplanar limit waist piece and two drift angle pieces) is another equilateral triangle outerplanar, three limits can arbitrarily be rotated except that heart piece, so that each outerplanar all is varied to irregular color (or pattern).Then continue as preceding rotation, recover initial state with prestissimo with the different spaces mode of thinking.
