EXPANSION JOINT STRUCTURE OF PIPE BODY

摘要

PROBLEM TO BE SOLVED: To provide the expansion joint structure of a pipe body which can be assembled easily and quickly. SOLUTION: In this expansion joint structure of a pipe body in which one end of joint pipes 7, 7a is connected swingably to the joint bodies 1, 1a for swing mounted on the ends of the pipe body which is a connection subject, the joint bodies 1, 1a for swing have expansion parts 5, 5a having spherical recessed surfaces 3, 3a and cylindrical installation parts 12, 12a extended from the expansion parts 5, 5a and expanded spherical surfaces 8, 8a provided on the joint pipes 7, 7a are inserted from the installation parts 12, 12a so as to be slidable to the spherical recessed parts 3, 3a and the come out stop rings 18 for regulating the separation from the joint bodies 1, 1a for swing are mounted between the installation parts 12, 12a and expanded spherical surfaces 8, 8a.
