Abstract

本实用新型公开了一种刻度圆规,圆规体和直尺,所述的圆规体的一个支架上设有卡口,其圆规体的另一支架上固定有直尺,所述的直尺的一端通过螺母固定在圆规体的支架上,其直尺的另一端活动连接在圆规体得另一支架上。本实用新型的有益效果是:在圆规体上固定有一直尺,调整圆规角度画圆,就可以知道所画圆的半径,结构简单实用方便。

Description

一种刻度圆规
技术领域
本实用新型涉及一种学习用具,具体涉及的是一种刻度圆规。
背景技术
圆规在数学和制图里,是用来绘制圆或弦的工具,常用于尺规作图,但每当学生使用圆规时,常遇到这样的麻烦,如画一个半径为4cm的圆,就得先要用圆规在直尺上量出距离再画出来,既不方便且误差也大。
实用新型内容
本实用新型根据上述不足,提供一种刻度圆规。
为实现上述目的,本实用新型的技术方案是一种刻度圆规,圆规体和直尺,所述的圆规体的一个支架上设有卡口,其圆规体的另一支架上固定有直尺,所述的直尺的一端通过螺母固定在圆规体的支架上,其直尺的另一端活动连接在圆规体得另一支架上。
本实用新型的有益效果是:在圆规体上固定有一直尺,调整圆规角度画圆,就可以知道所画圆的半径,结构简单实用方便。
附图说明
图1是本实用新型结构示意图。
具体实施方式
以下结合附图,对本实用新型作具体的说明一种刻度圆规,圆规体1和直尺2,所述的圆规体1的一个支架上设有卡口3,其圆规体1的另一支架上固定有直尺2,所述的直尺2的一端通过螺母4固定在圆规体1的支架上,其直尺2的另一端活动连接在圆规体1得另一支架上,在圆规体1上固定有一直尺2,调整圆规角度画圆,就可以知道所画圆的半径,结构简单实用方便。

Claims (2)

1.一种刻度圆规,圆规体和直尺,其特征在于:所述的圆规体的一个支架上设有卡口,圆规体的另一支架上固定有直尺。
2.根据权利要求1所述的一种刻度圆规,其特征在于:所述的直尺的一端通过螺母固定在圆规体的支架上,直尺的另一端活动连接在圆规体得另一支架上。
