Description

經濟部智慧財產局S工消費合作社印製 554137 A7 _ B7_ 五、發明説明（1 ) 背景技藝 過去’需要大工具，以在進行組裝與修理泵時施加足 夠的扭矩。當泵需要修理時，維修人員必須使用不方便及 笨重的工具，將泵與空氣馬達或其他往復式動力來源分離 〇 發明揭示 本發明免除了對於此大扭矩工具的需求。壓氣缸組裝 於上外殼的對應穴中。壓氣缸具有一平坦件，其對準上外 殻中的對準孔。鎖緊銷滑動通過對準孔，以沿著壓氣缸上 的平坦件旁邊行進，將二元件鎖在一起。組裝者可以藉由 孔對準上元件及壓氣缸上的平坦件而辨別下元件的正確位 置。此外，二元件可藉由簡單地移除鎖緊銷而拆卸。 而且，可以移除泵上的底閥，而無缸鬆開的危險。因 爲缸不隨著鎖緊銷之就定位而轉動，所以它不會由於衝擊 或其他一般的事件而鬆開。此使泵的維修及修理有關的安 全性增加。 從下列說明，配合附圖，可以更完全明白本發明的這 些及其他目的及優點，其中參考符號標示若干視圖中相同 或類似的零件。 圖式簡單說明 圖1是在拆卸位置之泵的上與下元件二者之側視圖， 而鎖緊銷係移除且置於一^旁。 本紙張尺度適用中國國家標準（CNS ) A4規格（210X 297公釐） _ 4 - (請先閱讀背面之注意事項再填寫本頁)
554137 經濟部智慧財產局8工消費合作社印製 A7 B7 五、發明説明（2 ) i g元件對照表 5 上外殻 7 缸 7a 平坦件 9 鎖緊銷 11 孔 13 缸端部 執行本發明的最佳模式 圖1中，上外殻5在未插入的缸7中。缸7的螺紋式 缸端部1 3將螺合於上外殻5中，直到它觸底，然後退出 ’直到對準孔11與缸1 3的平坦件7a之一對齊爲止。那 時候’鎖緊銷9可插入對準孔11且穿過平坦件7a，於是 鎖緊上外殻5與缸7。在拆卸的時候，使用者只需要從對 準孔11移除鎖緊銷9，且將缸端部1 3自上外殼5中的對 應穴拆下。 所慮及的是可對於壓氣缸鎖緊器作各種改變及修改， 不會偏離下列申請專利範圍界定之本發明的精神和範疇。 本紙張尺度適用中國國家標準（CNS ) A4規格（210X 297公釐） -5 - (請先閱讀背面之注意事項再填寫本頁)
