Abstract

本实用新型涉及一种既能书写,又能照明的笔,其主要特征在于能在黑暗中读写。该笔壳内的下部装有常用笔芯和扭转式笔芯伸缩装置,笔壳内的上部装置电源和开关,笔壳下部沿其圆周做出倒u形槽,其中安装有环形灯管。用导体把电池、开关和灯管连接成微型照明灯具,又由于倒u形槽的作用,该灯的光线仅能集中照射向笔尖处。

Description

夜光笔
本实用新型涉及一种既能书写,又能照明的多种用途笔。
普通笔只能书写,且必须在一定强度的光线下才能书写,有时为了保密或减少对外界的干扰,又必须在黑暗中读或写时,就得另备灯具,且需做隐蔽工作。
本实用新型的目的是要提供一种携带使用方便,能在黑暗中靠自身发光而进行较隐蔽的读或写的多种用途笔。
本实用新型的目的是这样实现的:在笔内下部装置常用笔芯及可使笔芯伸缩的扭转装置,笔的内上部装置电源,笔顶端装置开关,笔壳下部装置环形灯管,当按下开关时,灯管发光并集中照射向笔尖处进行读或写。
本实用新型的具体结构由以下实施例及附图给出。
图1是根据本实用新型提出的笔的剖面图。
下面结合图1详细说明依据本实用新型提出的笔的细节及工作情况。
该笔包括下笔壳(1)和上笔壳(2),笔壳(1)内装置笔芯(7)及扭转式笔芯伸缩装置(6),外下部沿笔壳圆周做出倒u形凹槽,并在该槽中装置特制的环形灯管(8)。笔芯(2)内装置电源(5),顶端装置按扭式开关(3),再用导体沿笔壳内壁,把开关和电源分别连接在环形灯管的两极上,电源正极与开关触头之间装设限位弹簧(4)。
当扭转上下笔壳时,笔芯(7)伸出书写。当按下开关(3)时,接通照明电路,灯管(8)发光。又由于灯管装在倒u形槽内,所以该灯光又仅能向笔尖处集中照射。

Claims (2)

1、一种能书写、能照明又能在黑暗中读或写画的笔,该笔有完整的笔壳(1)和(2),笔壳(1)中装置笔芯(7)及扭转式笔芯伸缩装置(6),其特征在于笔壳(2)内装置了电源(5)和开关(3),笔壳(1)下部沿笔壳圆周做出凹槽,并在其中装置一种特制的环形灯管(8);开关(3)、灯管(8)和电池(5)用导体沿笔壳内壁连接成一常开照明电路。
2、根据权利要求1所述的笔,其特征在于笔壳(1)下部安装灯管的凹槽做成倒u形,且凹槽的深度一定大于灯管直径。
