Description

本实用新型涉及一种书写工具,尤其是一种黑板书写笔。
目前用于书写黑板的笔多为两种:一是粉笔,二是沾广告色书写的毛笔或画笔。前者由于书写过程不断产生粉尘,于人体有害,且直接手抓粉笔书写亦很不卫生;后者适用范围小,又相当麻烦,例如逢喜庆节日要办黑板报,宣传员需准备好毛笔或排笔及广告色等,事后还必须用清水洗笔。给使用者带来不利和不便。
本实用新型的目的是提供一种使用方便、清洁卫生、书写流畅、易擦、手感好的黑板书写笔。
本实用新型由笔尖、笔头、海绵圈、泵、弹簧、笔管、钢珠、笔套等组成。
以下结合附图进一步详细描述。
图1为本实用新型结构示意剖面图。
图2为本实用新型双色笔笔管结构示意剖面图。
本黑板书写笔外形如粗钢笔状。笔尖(2)是长圆柱形,也可是长方形,它插入笔头(7)内且能随意抽出更换。中间空的圆锥形笔头(7)内有两个台阶,后部台阶内壁开有螺纹,与笔管(5)一头旋接,中部台阶内设置一让笔尖(2)穿过的海绵圈(8)。泵(3)为空心圆锥状,其大头抵着笔头(7)的后部台阶,紧套入并封住笔管(5)进口,小头中心为墨水输进管(4),弹簧(9)套在墨水输进管(4)上并抵住笔尖(2)的后端,泵(3)小头部份开有几条供墨水进出的空槽。笔管(5)可有单色管和双色管两种,单色管(5)中间直空,放有一个能自由滚动的小钢珠(6)。双色管(10)两头有进出口,中间设一隔叶(11);双色笔需多配一个没有笔插的小笔套,使两头都得以密封。
本黑板书写笔使用专用墨水,书写流畅,手感好,无粉尘污染,清洁卫生,易擦;其造型美观,携带方便,将是教师上课书写黑板得心应手的笔具。
