    • The present invention concerns an internal pipe coupler (100) comprising: a support (110) which internally supports a pipe (10); a guide member (130) which guides movement of the support (110) in the longitudinal and radial directions of the pipe (10); an operating member (150) which is movably joined with the guide member (130) and actuates the support (110); a connecting member (170) which connects the support (110) to the operating member (150); and a contact preventive member (190) which is interposed between the connecting member (170) and the operating member (150) so as to prevent a direct contact therebetween, thereby smoothening the movement of the operating member (150).
    • 本发明涉及一种内部管道联接器(100),包括:内部支撑管道(10)的支撑件(110) 引导构件(130),其引导所述支撑件(110)在所述管道(10)的纵向和径向方向上的运动; 操作构件(150),其与所述引导构件(130)可移动地接合并致动所述支撑件(110); 连接构件(170),其将所述支撑件(110)连接到所述操作构件(150); 以及插入在连接部件(170)和操作部件(150)之间以防止其间直接接触的接触防止部件(190),从而使操作部件(150)的移动平滑化。
