Abstract

多功能教学圆规是属于教学圆规结构的改进。本实用新型就是提供一种除可画圆之外,还可以画其它图形的多功能教学圆规。本实用新型包括附有量角器的吸盘,其结构要点吸盘上旋钮下固定有内有滑槽的直尺,滑槽内的固定器上设置有粉笔夹。

Description

多功能教学圆规
技术领域:
本实用新型是属于教学圆规结构的改进。
背景技术:
传统的教学圆规是以钢针为支点画圆,使用时支点不易固定,并且容易划伤黑板。另外,功能单一,需作其它几何图形时,还得配有直尺、圆规、量角器等。
实用新型内容:
本实用新型就是针对上述问题,提供一种除可画圆之外,还可以画其它图形的多功能教学圆规。
本实用新型采用如下技术方案:本实用新型包括附有量角器的吸盘,其结构要点吸盘上旋钮下固定有内有滑槽的直尺,滑槽内的固定器上设置有粉笔夹。
本实用新型的有益效果:
由于本实用新型吸盘上旋钮下固定有内有滑槽的直尺,滑槽内的固定器上设置有粉笔夹;由吸盘代替钢针,不伤黑板;可由吸盘为圆心准确画出任意半径的圆;可画出任意圆心所对应的弧度;可代替直尺测量长度;因此本实有新型具有多种功能,方便教师的教学活动。
附图说明:
图1是本实用新型的结构示意图。
具体实施方式:
本实用新型包括附有量角器5的吸盘6,吸盘6上旋钮7下固定有内有滑槽4的直尺3,滑槽4内的固定器2上设置有粉笔夹1。
使用时,可从量角器5上量取角度,可从直尺3量取长度;移动固定器2,定好半径尺寸后,以吸盘6为圆心就可画出圆。
