The invention provides a bulk type pipe joint provided with a special connecting pipe into which a confirming mechanism can be inserted, wherein the insertion of the connecting pipe and the connecting operation are simple, and the pipe joint can be used for easily and accurately grasping whether the inserted connecting pipe reaches any determined position in the pipe joint during connection. The pipe joint is characterized by being provided with a C-type annular or O-type annular part which is of a radiate extensional flexible rod-shaped part and is arranged in the accommodating part of the pipe joint. By virtue of adjusting the length of the rod-shaped part, when the connecting pipe is inserted, the annular part is pressed in an inner direction by the connecting pipe, the rod-shaped part which is previously arranged in a through hole can be pulled into an outer barrel body from the exterior of the outer barrel body, and the inserting confirming position of the length of the connecting pipe relative to the accommodating part of the pipe joint is freely changed. |
