Abstract

本新型公开了一种充气笔,由压缩气囊1、笔杆气囊、笔液囊3、笔尖5、复位弹簧6、气阀7、8、9组成。给气囊1加压,气阀7关闭,气阀8开启,气压进入笔杆气囊内.气阀9关闭,笔尖5伸出笔杆囊,即可书写;打开气阀9,笔杆气囊内的气逸出,笔尖5缩回笔杆囊中,即可卷折存放。

Description

充气笔
本实用新型涉及人们日常书写运用的笔类,特别是圆珠笔。
目前人们书写所用的笔类,虽然不存在运用上的困难,却存在以下缺点:笔杆为金属或其它硬性材料制作,呈刚性,易折损,而且不便携带,专为便携而设计的笔类,使用时又嫌小巧难握。
本新型充气笔一改传统笔不可变的刚性为可变的柔性,在充气后方便书写,放气后形体变软、变小,便于携带,不易损坏。
为实现上述任务,本新型由压缩气囊、笔杆气囊、气阀、笔液囊、笔尖组成。使用时,持续给压缩气囊加压,气体便被压入笔杆气囊,待笔杆气囊达到一定硬度,便可用于书写;打开笔杆气囊上的气阀,气体逸出,笔杆气囊空瘪,便可随意卷折。
下面结合附图对本充气笔作进一步详细说明:
本图是充气笔的侧视示意图。图中,空气压缩气囊1是用纤维增强的橡胶或其它弹性材料制作,它受压后变形但不膨胀,减压后自动复原。笔杆气囊的外层2是纤维与气密材料制作,两者的结合可以使气囊充气后硬挺,不会象气球一样膨胀,内层3可以是橡胶或其它材料制作,内外层之间就是笔液囊4,笔液囊内所盛的笔液的浓度须高于普通的圆珠笔液,以防在气囊加压后笔液由笔尖5喷涌。笔尖5一端固定于笔液囊内,笔尖5与笔杆气囊外层2之间设有弹簧6,当笔杆气囊充气时,笔尖5被气压压出笔杆气囊,放气后,在弹簧6的张力下,笔尖5缩回笔杆囊内,这样可以免去笔尖护套。也可以把笔尖5与笔液囊3用弹性材料连接,以省去弹簧6。7是压缩气囊的进气阀,8是笔杆气囊的进气阀,9是笔杆气囊的放气阀,三个气阀在满足功能的前提下,应尽量小化、柔化,以便于改卷。当给压缩气囊1加压时,气阀7被压紧闭,气阀8被压打开,气被压进笔杆气囊中,笔杆囊上的气阀9被压紧闭,放松压缩气囊1,气阀8被笔杆气囊内的气压紧闭,气阀7在大气压下打开,压缩气囊1复原。重复给气囊1施压,能持续给笔杆气囊充气加压,笔尖5在压力下伸出笔杆气囊外,当压力使笔杆气囊硬挺,即可握之书写;打开气阀9,笔杆气囊内的气逸出,笔尖5也随之缩回笔杆气囊,充气笔便可卷折收存。

Claims (2)
