Abstract

一种书写与绘图用具,笔芯由多个同轴重叠的书写单元构成,每个书写单元包括一笔芯套嵌紧一笔内芯。一个书写单元的笔内芯写完后,可以方便换用另一书写单元。

Description

本实用新型涉及一种书写与绘图装置的制作。
现有的笔如铅笔蜡笔等的内芯均为通长的,使用时或者需要不断削制笔尖,较为费时费事。
本实用新型的目的为制作一种多个书写单元重叠的笔。
本实用新型的技术解决方案是:笔的笔芯为多个书写单元同轴重叠组成,每个书写单元包括一笔内芯及一笔芯套,笔内芯在笔芯套的一端嵌紧,笔芯套的另一端可供另一单元笔内芯自由伸入,组成每支笔的书写单元,可为3至13个。笔内芯与笔芯套的配合可以有两种结构:一种是套内壁带有小角度的锥度,另一种是在内芯套设一隔层将嵌紧笔芯的一端隔开。笔内芯主要是石墨、彩色蜡质成型的柱形笔内芯,也可是短园珠笔芯或其它带油墨的笔的内芯,笔芯套为工程塑料等材料注塑成型。本实用新型是可为循环使用多个书写单元的笔,特别适合小学生使用,一支相当于多支削好的铅笔,也节约了铅芯,可重复使用。绘图时可装有从软到硬的多种绘图铅笔芯,还可装有多种彩色铅笔芯,给绘画、彩画、书写等带来方便。
以下结合附图对本实用新型作进一步说明:附图为重叠式笔的结构示意图。笔芯套3,笔帽6,笔杆1由注塑或其它热塑性材料制成,笔内芯2为铅芯,笔芯套上嵌紧笔芯的一端设一凸台阶4,另一端5开孔较大,可供另一书写单元的笔内芯插入及凸台阶配合组成同轴多书写单元铅笔,当最尖端书写单元铅芯写完后,从笔头拔出写完笔芯的单元,将此笔芯套从尾部塞进笔杆,露出另一书写单元笔芯,笔帽在笔杆内设有一止凸7。

Claims (2)

1、一种重叠式笔,由笔芯,笔杆组成,其特征是所述的笔芯为3-13个同轴重叠的书写单元组成,每个书写单元包括一笔内芯及一笔芯套,笔内芯嵌紧笔芯套的一端,即笔芯套的此端内径较小并带有锥度,或者在笔芯套内设一隔层,笔芯套的另一端内径较大以供另一书写单元的笔芯自由伸入。
2、由权利要求1所述的笔,其特征是笔芯套的两端分别设有凹凸台阶:笔芯端的凸台阶嵌于另一书写单元笔芯套的凹台阶内以利笔芯同轴重叠。
