摘要:一种定量输液泵,其中一液体输出管2沿着泵壳31圆柱形内表面放置。滚子34压迫和挤压液体输出管2以从其中输出液体。滚子轴支承36位于回转体32中心,U形滚子轴35各有第一和第二直腿。第一直腿支撑有关的滚子34,第二腿由滚子轴支承支撑。在回转体32中有弧形槽38,并绕滚子轴支承36设置,并从径向离开滚子轴支承36的一位置沿回转体32的回转方向延伸。直腿末端分别插入弧形槽38中。此种泵可使操作者方便而可靠地更换输出管,且结构简单。

主权项:1.一种定量输液泵,其特征在于,它包括:一具有圆柱形内表面的泵壳;一回转体,其转动中心与泵壳圆柱形内表面中心轴线一致,所述回转体具有多个等距沿在泵壳圆柱形内表面排列的滚子;一柔性液体输出管设置得与所述泵壳圆柱形内表接触,当所述回转体沿一固定转动方向转动时,所述滚子压迫和挤压所述液体输出管以从所述液体输出管输出液体;多个各自具有第一和第二直腿的U形滚子轴,所述第一直腿可转动地支撑一滚子,而所述第二直腿由位于所述回转体中心部分的滚子轴支承中的一个可转动地支撑;以及形成于所述回转体上的弧形槽,各个所述弧形槽分别都绕所述相关的滚子轴支承设置,并且从一径向离开所述滚子轴支承的位置上沿回转体转动方向延伸,所述弧形槽容纳可转动地支撑所述滚子的所述U形滚子轴的所述直腿末端。
