Abstract

魔三角属于一种智力玩具，其特征是由四个正八面体、四个顶角正四面体、六个边侧正四面体和一个空间对称的四臂心轴组成的一个外形着四色的正四面体，通过绕四臂心轴各轴作顺、逆时针转动，达到同一平面上色彩的组合，从而使学生在娱乐的同时提高空间想像能力。

Description

魔三角
本实用新型属于一种智力玩具。
根据中国专利ZL93205645.8公开的魔角，其是由边体，角体平面中心体，中心球体，三角平面中心旋转轴，颜色片组成，正四面体的四个不同颜色面可绕各自的三角平面旋转轴左右转动。由于其结构复杂，给制造带来了一定的难度，并且转动不灵便，角体也容易引起对人的误伤。
本实用新型的目的是提供一种结构简单，转动方便，学生娱乐安全可靠，生产成本低廉，适合中小学生使用的智力玩具。
为达到此目的，本实用新型采用了四个顶角正四面体，六个边侧正四面体，四个正八面体和一个在空间对称的四臂心轴组成。四个正八面体顶部的正三角形面中心开有圆孔，底部挖空，分别套在心轴的四臂上，挖空面朝轴心。位于此魔三角顶端的四个顶角正四面体，在其与正八面体相叠的正三角形面中心，开有一个与心轴顶端的弹性卡扣相配的圆孔，四臂心轴顶端卡扣从其中伸进卡入。其余空隙嵌入各带有二个搭扣的六个边侧正四面体，其每一个都有二个正三角形面分别与不同二个正八面体的正三角形面相叠，并且与正八面体圆弧攀口扣接。
本实用新型与以往此类智力玩具相比，提供了一种全新结构的正四面体的智力玩具，通过绕四臂心轴各轴作顺、逆时针转动，达到同一平面上色彩的排列与组合，从而使中、小学生在趣味性娱乐的同时提高空间想像能力。
下而结合附图和实施例对本实用新型作进一步的说明：
图1是魔三角的立体图
图2是魔三角的局部立体图
图3是正八面体的立体图
图4是顶角正四而体的立体图
图5是边侧正四面体的立体图
图6是正八而体的空间三维视图
图1是魔三角的一个立体图，它是一个正四面体，四个顶角制成抛物球面形，外观面为不同的四种颜色面，可以采用塑料或木料制成。顶角正四面体2、边侧正四面体3及正八面体1，它们每一个正三角形面都是相同的。四臂心轴4在空间是对称的，轴端设有弹性卡扣7。四个正八面体1顶部的正三角形面中心开有一个直径略大于轴直径的圆孔5，底部挖空11，分别套在心轴四臂的内端，挖空面朝轴心。心轴四臂的外端是四个顶角正四面体，通过其底面中心上的一个与轴的弹性卡扣7相配的园孔8，与轴卡接，并能方便地绕该轴转动。其余空隙嵌入六个边侧正四面体3，其每一个都有二个正三角形面分别与不同二个正八面体的正三角形面相叠，并且它们之间是通过边侧正四面体上的搭扣9与正八面体上的圆弧攀口6进行扣接，同时它们延园弧能作相对移。见图2，园弧攀口的园弧大小，设计成三个正八面体的园弧攀口在一个平面内组成的以轴为中心的一个园10的三分之一。
