Abstract

本实用新型公开了一种改进的教学圆规,该教学圆规包括一个交点下的两个支撑腿,其中用来确定圆心的支撑腿的端部通过吸盘套联接着一个吸盘,在两支撑腿上刻有刻度。该教学圆规不但在黑板上容易的确定圆心,方便的画圆,而且还可以作直尺用。

Description

一种改进的教学圆规
本实用新型涉及一种教学器具,特别是一种教学画图用的圆规。
现行的圆规是两个支撑腿,其中一个支撑腿的端部安装画笔,另一个支撑腿的端部是一个尖状钢针,主要用来画圆,这种圆规在纸面上画圆较好,但如果教学中在黑板上画圆就不好用,其原因是支撑腿上的尖状钢针容易在黑板上打滑,圆心不好确定。
本实用新型的目的就是针对现行圆规在教学上存在的问题,而设计的一种在黑板上画圆不打滑,容易确定圆心的圆规。
本实用新型的目的是这样实现的,该教学圆规包括一个交点下的两个支撑腿,其中一个支撑腿用来确定圆心的,另一支撑腿用来安装画笔,所述用来确定圆心的支撑腿的端部通过吸盘套联接着一个吸盘,在两支撑腿上刻有刻度。
由于采用上述结构,该教学圆规不但在黑板上容易的确定圆心,方便的画圆,而且还可以作直尺用。
下面结合附图详细说明本实用新型的实施例
图1为教学圆规的示意图
图中:1、交点  2、确定圆心支撑腿  3、画笔支撑腿  4、笔管套  5、吸盘套  6、吸盘  7、刻度
交点(1)下有两个支撑腿,确定圆心的支撑腿(2)的端部通过吸盘套(5)联接着一个吸盘(6),支撑腿(3)的下部通过一笔管套(4)联接画笔,两支撑腿上刻有刻度(7),可作为直尺用。
