Abstract

本新型有两种样式,第一种是少量增加常见笔筒的内径而不增加其长度,利用塑料笔芯管的弹性,在笔筒中能同时容纳尺寸规格相同的两支常见圆珠笔芯,笔芯尾部插入筒管中并固定于笔芯尾部固定柱B上,让两笔尖分别从两端伸出,使圆珠笔两端都可书写。第二种是少量增加笔管的长度和内径,也能同时容纳尺寸规格相同的两支常见圆珠笔芯,笔芯尾部插入筒管中并固定于笔芯尾部固定柱B上,让两笔尖分别从两端伸出,使圆珠笔两端都可书写。本新型都由两个螺旋笔筒帽A,两个笔芯尾部固定柱B,筒管 C及两个笔筒盖组成。本新型的横截面可以是圆形,椭圆形也可以是方形。笔筒均采用对人无害的塑料为制造原料,两种新型笔筒增大了容量并节约了成本。

Description

两种能同时容纳两根相同笔芯的圆珠笔笔筒
技术领域
本实用新型涉及新式笔筒,尤其涉及在少量增加现有圆珠笔笔筒的长度及内径的情况下同时容纳两只相同笔芯的两种笔筒。 
背景技术
现有的绝大多数圆珠笔笔筒只能放进一支笔芯,两种不同色彩的笔芯就要用两根笔筒来装,使用过程中易造成浪费及不便。本实用新型提供一种只要少量增加现有圆珠笔笔筒的长度及内径的情况下同时容纳两只相同笔芯的笔筒。 
发明内容
本新型有两种样式,第一种是少量增加常见笔筒的内径而不增加其长度,利用塑料笔芯管的弹性,在笔筒中能同时容纳尺寸规格相同的两支常见圆珠笔芯,笔芯尾部插入筒管中并固定于笔芯尾部固定柱B上,让两笔尖分别从两端伸出,使圆珠笔两端都可书写。第二种是少量增加笔管的长度和内径,也能同时容纳尺寸规格相同的两支常见圆珠笔芯,笔芯尾部插入筒管中并固定于笔芯尾部固定柱B上,让两笔尖分别从两端伸出,使圆珠笔两端都可书写。本新型都由两个螺旋笔筒帽A,两个笔芯尾部固定柱B,筒管 C及两个笔筒盖组成。本新型的横截面可以是圆形,椭圆形也可以是方形。笔筒均采用对人无害的塑料为制造原料,两种新型笔筒增大了容量并节约了成本。 
附图说明    
图1为两种能同时容纳两根相同笔芯的圆珠笔笔筒的结构示意图。
 图1中左图为少量增加常见笔筒的内径而不增加其长度的笔筒的结构示意图。
图1中右图为少量增加笔管的长度和内径的笔筒的结构示意图。 
图1中A均为螺旋笔筒帽,B均为笔芯尾部固定柱,C为筒管。
 图2,图3和图4分别为两种笔筒的圆形,椭圆型及方形剖面图。
图5为笔筒盖的剖面图。 
具体实施方式
本新型均采用对人无害的塑料为制造原料,都由两个螺旋笔筒帽A,两个笔芯尾部固定柱B,筒管 C及两个笔筒盖组成。可使用圆珠笔厂的原有机械大量生产,成本增加不多却使容量加倍,也延长了笔筒的使用时间,既节约又环保。使用时只要旋开螺旋笔筒帽,将笔芯尾部插入筒管中并固定在笔芯尾部固定柱上,旋紧笔筒帽就可书写,不用时再盖上笔筒盖即可。
