Title: Fixing construction of joint into joint storing box
Inventor: KANAMORI YOSHIHARU
IPC: F16L5/00
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To enlarge combining force of a fixing ring against a fixing ring threadedly fitting port by forming buttress thread of which the face of the thread ridge positioned on this side by view from the front formed on a fixing ring is almost vertical, on the respective circumferential faces of the fixing ring and the ring threadedly fitting port. SOLUTION: A short cylindrical fixing ring threadedly fitting port 7 is integratedly provided on the front face of a box main body 1. Internal thread 9 is formed on the inner circumferential face of the fixing ring threadedly fitting port 7. The thread ridge of the internal thread 9 is formed into a saw- blade-shape so that the face positioned on the depth side by view from the front face F is nearly vertical. A fixing ring R is provided with the outer diameter corresponding to the inner diameter of the fixing ring threadedly fitting port 7, and external thread 17 corresponding to the internal thread 9 is formed on the outer circumferential face.  By forming the thread ridge into a saw-blade- shape, the contact area of the thread part becomes large, and hence the combining force of the fixing ring R against the fixing ring threadedly fitting port 7 becomes large, so as to increase supporting force of a used device against a joint C.
