Description

便于度量刻度的圆规
技术领域
本实用新型属于文具用品技术领域,具体涉及一种便于度量刻度的圆规。
背景技术
使用圆规画圆时,通常先用固定支脚和绘图支脚在直尺上卡出相应的半径,然后进行描绘,这种做法不方便且浪费时间。
发明内容
本实用新型的目的是提供一种便于度量刻度的圆规,能够快速画出需要半径的圆,结构简单且操作方便。
本实用新型所采用的技术方案是,一种便于度量刻度的圆规,包括圆规头,圆规头的下方设置有可活动的绘图支脚和固定支脚,固定支脚的外表面上通过转轴固定有刻度尺。
本实用新型的有益效果是,通过在固定支脚外表面设置可旋转的刻度尺,从而可以快速方便的画出需要半径的圆。
附图说明
图1是本实用新型便于度量刻度的圆规的结构示意图;
图2是本实用新型便于度量刻度的圆规的使用状态示意图。
图中,1.圆规头,2.绘图支脚,3.固定支脚,4.刻度尺。
具体实施方式
下面结合附图和具体实施方式对本实用新型进行详细说明。
本实用新型便于度量刻度的圆规的结构,如图1及图2所示,包括圆规头1,圆规头1的下方设置有可活动的绘图支脚2和固定支脚3,固定支脚3的外表面上通过转轴固定有刻度尺4。
画圆时,如图2所示,通过转轴旋转刻度尺4至水平,以固定支脚3确定圆心,用绘图支脚2在刻度尺4卡出需要的半径,从而画出需要的圆。描绘完毕后,旋转刻度尺4至和固定支脚3贴合即可。
本实用新型便于度量刻度的圆规,通过在固定支脚外表面设置可旋转的刻度尺,从而可以快速方便的画出需要半径的圆。
