Abstract

本实用新型涉及画图工具,特别是一种图尺。该尺由直尺和带有直尺的半圆尺组成,直尺与带有直尺的半圆尺通过连接轴连接,直尺自由转动在带有直尺的半圆尺上。本实用新型具有结构简单、使用方便、成本低、功能齐全等优点。

Description

一种图尺
本实用新型涉及画图工具,特别是一种图尺。
目前在中学教学中,特别是在教力学时,初步一般都用作图法来讲解作用于任何一点的成某一夹角的两个力的合成力的概念。在用力的四边形作图法中,学生常会遇到困难,不能正确画四边形,导致解出错误的结果,而且在数学、几何、物理课教学中,画各种图时,一般轮流用直尺、三角迟和半圆尺,对教师和学生来说很不方便。
本实用新型的目的是,解决上述问题,提供一种作图方便、快速而正确的图尺。
本实用新型是这样实现的:该尺由直尺和带有直尺的半圆尺组成,直尺与带有直尺的半圆尺通过连接轴连接,直尺自由转动在带有直尺的半圆尺上,直尺上表有长度刻度和剑头,带有直尺的半圆尺上表有角度刻度和长度刻度和剑头。
本实用新型具有结构简单、使用方便、成本低、功能齐全等优点。
附图是本实用新型的结构示意图。
下面结合附图,对本实用新型作进一步说明。
如图所示,本实用新型由直尺1和带有直尺的半圆尺2组成,直尺1与带有直尺的半圆尺2通过连接轴3连接,直尺1自由转动在带有直尺的半圆尺2上,直尺1上表有长度刻度和剑头,带有直尺的半圆尺2上表有角度刻度和长度刻度和剑头。使用时,把直尺1上的剑头对准半圆尺上所需的角度,这时直尺1与带用直尺的半圆尺2交叉而产生夹角的度数与剑头所指的角度一样。这样很容易画出夹角为1-179度的各种四边形、三角形和梯形或各种电路图。
