る。[Effect of the Invention] Since the fire hydrant of the present invention is constructed as described above, it has the following operational effects. By turning the female screw at the lower opening of the hollow head into the male screw at the upper end of the water pipe by screwing the hollow head itself and screwing it in, the lock nut previously attached to the upper end of the water pipe is turned and fastened. , O-rings are elastically compressed at the lower opening of the hollow head and the respective end surfaces of the lock nut, and the reaction force of the O-rings effectively prevents loosening of the screwing of the hollow head, and It can be easily connected to the upper end.
Further, in the replacement work when the hollow head having the water discharge port is damaged, the hollow head can be easily removed by rotating the hollow head after loosening the lock nut, and a new one can be easily attached. Further, the O-ring sandwiched between the end faces of both members and compressed is elastically brought into close contact with the threaded gap between the upper end of the water pipe and the opening of the lower portion of the hollow head. You can keep good.
