SPIGOT-AND-SOCKET PIPE JOINT HAVING ANCHORING FUNCTION, INSTALLATION METHOD AND INSTALLATION CARD

摘要

A spigot-and-socket pipe joint having an anchoring function; a retaining ring (2) of the joint has a separated structure and comprises a plurality of stoppers (1); two or more fixing holes (4) for installing a rubber support piece (5) are disposed on the outer diameter surface of each stopper (1). During installation, first, installing the stoppers (1) one by one into stopper positions (7) forming an integral piece, then, installing the spigot (8) into the socket (9). In the installation process, when protruding to pass through the retaining ring (2), the spigot (8) pushes the stoppers (1) to move backward and compress the rubber support piece (5) on the retaining ring (2), and after protruding to pass through the retaining ring (2), the spigot (8) is pulled back to enable the stoppers (1) to tightly press against the outer surface of the spigot (8) under the action of the rubber support piece (5). The spigot-and-socket pipe joint having an anchoring function has a simple structure, good slippage prevention ability and wide application range, and is easy to install.
