发明名称 Joint structure for jointing metal pipes at their ends
摘要 Herein disclosed is a joint structure for jointing the ends of two pipes to each other. One pipe has its one end portion formed with a plurality of slots arrayed circumferentially in its wall and with an inward projecting annular wall or a tapered annular wall positioned axially inside the slots to provide a receiving seat surface facing the other pipe. This other pipe is formed generally at its tip with a reduced annular wall providing a pushing seat surface and with at least one engagement groove positioned axially at the back of the reduced annular wall and extending in the circumference. These two pipes are jointed together by holding the inward projecting or tapered annular wall in abutment against the seat surface of the reduced annular wall, by fastening that one pipe at its portions of the slots in the engagement groove to reduce and deform it.
