Abstract

本实用新型公开了一种生产用圆规,由手柄、轴、定脚和转脚构成,其特征在于在定脚的上端添加量尺,量尺上刻有刻度。当画圆时,调整转脚,转脚的边上的刻度就是画圆半径的尺寸。本实用新型结构简单,实用方便,制造容易,画圆精确。

Description

一种生产用圆规
技术领域
本实用新型涉及生产工具领域,特别是一种生产用圆规。
背景技术
目前,我们生产用的圆规是由手柄、轴、定脚和转脚构成,在生产中画圆,多是用尺子量好定脚和转脚的距离,就是所要画圆的半径,量好距离,再用圆规画圆,如没有尺子,无法画出所需的圆,非常不方便,也不精确。
发明内容
本实用新型克服现有生产用圆规画圆需用尺子进行测量后再画,既不方便,也不精确的不足,本实用新型提供了一种带有刻度的圆规,在画圆之前无需用量尺量两脚的距离,可直接调节转脚的位置就能画出所需的圆,既方便,又精确。
本实用新型为解决其技术问题采用的技术方案是:一种生产用圆规,由手柄、轴、定脚和转脚构成,其特征在于在定脚的上端添加量尺,量尺上刻有刻度。当画圆时,调整转脚,转脚的边上的刻度就是画圆半径的尺寸。
本实用新型的有益效果是:本实用新型结构简单,实用方便,制造容易,画圆精确。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1是本实用新型结构示意图。
在图1中,1、手柄,2、轴,3、量尺,4、定脚,5、转脚。
具体实施方式
在图1中,手柄(1)安装在最上端,手柄(1)与轴(2)连接,轴(2)将定脚(4)和转脚(5)连接在一起,定脚(4)和转脚(5)可以以轴(2)为支点向外展开和闭合,定脚(4)上端安装量尺(3)。
