Abstract

本实用新型技术属于绘图工具。适用于大、中专工科院校的学生作业和工程技术人员绘制建筑、机械等图纸。其特征是,在三角板上钻数个尖孔,每个孔中装入滚珠,使滚珠下部凸出三角板底面。这样,就能减少作图时间,提高图面质量,避免三角板底面与图纸面摩擦,保证图纸清洁。便于携带和保管。

Description

本实用新型属于绘图工具。
现有三角板在图纸上移动时,与图纸发生摩擦,容易把铅笔线擦淡。描图时,稍不小心,尺边上的墨就会浸入尺身,弄脏图纸。严重时造成前功尽弃。
本实用新型的目的就是提供一种可以克服以上不足的绘图工具。
本实用新型是这样实现的。如附图1、2所示。附图1是三角板,附图2是任意滚动装置的剖面图。图中2为滚珠,3为盖板。在三角板上钻数个尖孔,每个孔中装入滚珠2,再在滚珠2上盖一块带有尖孔的小板3,该板嵌入或粘在三角板上,使滚珠下部凸出三角板底面。三角板既可以在图纸上滚动,又可以与纸面保持一定的距离。
装有滚珠的三角板,能向任意方向滚动。画铅垂线和平行线时,三角板与丁字尺配合。以丁字尺导向,就可以画出所需方向的铅垂线和平行线。也可以把三角板转向需要的角度,画出你需要的角度线。
本实用新型技术属于绘图工具。适用于大、中专工科院校的学生作业和工程技术人员绘制建筑、机械等图纸。功能全,具有直尺、量角器、比例尺和建筑、机械模板等功能。能减少作图时间,提高图面质量,避免三角板底面与图纸面摩擦,保证图纸清洁。便于携带和保管。
