Abstract

一种绘图工具,包括具有一尖端的圆滑杆,其上 配置能上下滑动和转动的“T”形滑套笔架,绘笔铰接 在滑套笔架上。本实用新型能迅速准确地画出所需 椭圆和正圆,操作简便,并且结构简单,非标准件少, 加工容易。

Description

本实用新型涉及一种绘图工具,特别是一种正圆椭圆两用规。
目前还设有一种能简便准确地画出椭圆的工具。申请CN88203337U公开了可画出椭圆和正圆的多功能规,但均存在结构复杂、非标准件多、加工困难等不足之处。
本实用新型的目的在于提供一种结构简单、使用方便、非标准件少、加工方便的正圆椭圆两用规。
本实用新型包括具有一尖端的圆滑杆,其上配置能上下滑动和转动的“T”形滑套笔架,绘笔铰接在滑套笔架上。
使用时,调节绘笔尖端到圆滑杆尖端距离,使之等于欲画椭圆的短半轴长度,将圆滑杆尖端置于椭圆中心,调节圆滑杆倾角并使之始终位于经过椭圆长轴且与纸面垂直的平面内,转动绘笔使之画出的线条经过长半轴端点,这样绘笔在纸面上可画出所需椭圆。本实用新型能迅速准确地画出所需椭圆和正圆,操作简便,并且结构简单,非标准件少,加工容易。
图1为本实用新型结构图。
图2为包含支架的结构图。
如图1所示,本实用新型包括圆滑杆1,滑套笔架3可在其上滑动和转动,绘笔2铰接在滑套笔架3上。
图2中支架6具有二个分支,圆滑杆连接在支架6的一个分支上,其另一个分支端点连接有“T”形支脚,使用时将该支脚中点置于欲画椭圆长轴上,可保证支架及圆滑杆在绘图过程中不会偏离所在平面。图中4是加长杆。实际使用中支架6可用普通圆规的支架代替。

Claims (2)

1、一种正圆椭圆两用规,其特征在于包括具有一尖端的圆滑杆,其上配置有能上下滑动和转动的“T”形滑套笔架,笔头铰接在滑套笔架上。
2、按权利要求1所述的两用规,其特征在于该圆滑杆连接在一个具有二个分支的支架的一个分支上,该支架另一个分支端部设有“T”形支脚。
