Description

具有套管式笔杆的自动铅笔
本实用新型涉及文化用品,一种具有套管式笔杆的自动铅笔。
目前,市售的自动铅笔种类繁多,但尚无带橡皮擦的自动铅笔,中国实用新型专利,公告日1992.9.2,公告号CN2114570U公开了一种橡皮擦头固定在笔杆的活动铅笔,其结构是橡皮擦头直接固定在笔杆的尾端,橡皮下杆侧有推进块,推进块通过笔杆上的通槽与杆内的扶正套联结,扶正套套在储铅筒的上部,扶正套与储铅筒上端对接,按压推进块,使扶正块下行,迫使储铅筒下行,方可推动活动铅笔前端的送铅机构使铅送出。该活动铅笔的笔杆是整体结构,笔杆外表面光滑,握笔容易滑动,另外,储铅筒一次容纳一支铅芯,其他铅芯另外保存,不便于装铅。
本实用新型的目的是鉴于现有技术存在的缺点,提供一种笔杆外表面有摩擦粒、套管形式的自动铅笔。
本实用新型套管自动铅笔的技术方案:
一种由笔头、套管式笔杆、橡皮组成的自动铅笔,其特征在于笔管中间握笔部位为插入式套管结构,笔杆的外表面有摩擦粒,笔杆尾端设有橡皮托架。
本实用新型带橡皮的自动铅笔特点是:出铅速度快,储铅量多,外形美观,使用方便。
图1是套管式笔杆的自动铅笔结构剖面图。结合附图详细说明并给出实施例:
从图1可以看出,该自动铅笔为中间断开的套管式笔杆,外套管7的内径与内套管10的外径匹配插入连接,外套管7后端外表面设有摩擦粒8,内套管10中部外表面也设有摩擦粒8,两处摩擦粒均位于握笔手接触部位,内套管10后端部有橡皮托架11,其剖面呈H型,一端插在笔杆上,另一端插入橡皮12用胶粘在托架上,内套管10内腔中外侧空腔为储铅室9,中心空腔为下铅筒13,其前端深入到外套管7中间与送铅装置对接,内套管10的前端部外径与弹簧托架6内侧匹配插接,内套管10前端部呈有中孔的圆台14,圆台14插入弹簧5内侧卡在内套管10前端部的边沿上,弹簧5的另一端面座落在弹簧托架3上,当将内套管10压下时,弹簧5处于压缩状态,迫使铅条送进器4将铅条由铅条道1送出,铅条道1位于锥形笔头2中部。
