Title:
SEPARATION-PREVENTING PIPE JOINT AND PIPELINE CONFIGURATION MEMBER
Document Type and Number:
WIPO Patent Application WO/2015/111303
Kind Code:
A1
Abstract:
Provided is a separation-preventing pipe joint in which not only can a high separation-preventing function be achieved, but the separation-preventing pipe joint can also assembled on-site with a small amount of labor and time, and the bending angle of the pipe joint can be adjusted. A metal lock ring (7) that can hook on an insertion protuberance (5), and a cushion material (8) that comes in contact with a bottom surface part (3a) and a side surface part (3b) on the receiving hole opening side in a lock-ring-accommodating groove (3), are accommodated in the lock-ring-accommodating groove (3), the cushion material (8) being configured from a softer material than the lock ring (7). This makes it possible for a receiving hole (1) and an insertion hole (2) to be reliably prevented from separating even when pull-out force caused by water pressure acts on the pipe, and to achieve a highly reliable separation-preventing function.
