Abstract

本实用新型公开了一种吸盘圆规,包括左规脚和右规脚,所述左规脚和右规脚的上端通过螺栓相连接,所述左规脚下端设置笔孔和卡环,所述右规脚下端设置吸盘,所述右规脚和吸盘通过轴承相连接。由于本实用新型吸盘圆规将老式圆规右规脚下端的针尖改为轴承和吸盘,使用时吸盘能将黑板或纸紧紧地吸附,从而将右规脚牢牢的固定。这时整个圆规在轴承的作用下可以灵活的转动,人们就能在黑板或纸上轻松自如的画圆了。这就避免了老式圆规针尖容易在黑板上或纸上打滑的缺点,既使用方便,又避免了一定程度的浪费。

Description

吸盘圆规
技术领域
本实用新型属于常用文具技术领域,特别涉及一种吸盘圆规。
背景技术
教师在教学中经常在使用圆规在黑板上画图,但由于黑板的表面十分光滑,圆规的针尖很难固定在圆心位置上,所以往往需要几次才能画出一个圆,耽误了教学时间,影响了教学的效率。如果针尖在黑板上打滑,还会发出刺耳的声音,影响师生们的心情。而学生在学习时也会面临同样的问题,圆规的针尖能同时刺穿几页纸,使后面没有用过的纸也留下很深的针扎印迹,影响作业本以后的使用,有时甚至出现针尖在纸上打滑撕破很多张纸的现象,这就造成了一定程度的浪费。
实用新型内容
本实用新型提供一种结构简单、使用方便、不易打滑的吸盘圆规。
一种吸盘圆规,包括左规脚和右规脚,所述左规脚和右规脚的上端通过螺栓相连接,所述左规脚下端设置笔孔和卡环,所述右规脚下端设置吸盘,所述右规脚和吸盘通过轴承相连接。
由于本实用新型吸盘圆规将老式圆规右规脚下端的针尖改为轴承和吸盘,使用时吸盘能将黑板或纸紧紧地吸附,从而将右规脚牢牢的固定。这时整个圆规在轴承的作用下可以灵活的转动,人们就能在黑板或纸上轻松自如的画圆了。这就避免了老式圆规针尖容易在黑板上或纸上打滑的缺点,既使用方便,又避免了一定程度的浪费。本实用新型结构简单、使用方便,是一种理想的教学用品。
附图说明:
下面结合附图对本实用新型做进一步地说明:
图1是本实用新型的结构示意图。
具体实施方式
如图1所示:一种吸盘圆规,包括左规脚1和右规脚2,所述左规脚1和右规脚2的上端通过螺栓3相连接,所述左规脚1下端设置笔孔4和卡环5,所述右规脚2下端设置吸盘7,所述右规脚2和吸盘7通过轴承6相连接。
本实用新型吸盘圆规将老式圆规右规脚下端的针尖改为轴承和吸盘,使用时吸盘能将黑板或纸紧紧地吸附,从而将右规脚牢牢的固定。这时整个圆规在轴承的作用下可以灵活的转动,人们就能在黑板或纸上轻松自如的画圆了。这就避免了老式圆规针尖容易在黑板上或纸上打滑的缺点,既使用方便,又避免了一定程度的浪费。
