PIPE COUPLER HAVING ADHESION PART

摘要

The present invention comprises: a pipe-shaped socket in which a hanging protrusion is formed on the inner surface and a pipe is inserted to be connected to each other; an O-ring placed on the hanging protrusion formed on the inner surface of the socket, and coupled to the outer surface of the pipe inserted into the socket; a grab ring placed on the end of the socket, and having multiple elastic pieces inclined forward in a direction where the pipe is inserted; a screw cap coupled to the outer surface of the socket in a state where the pipe is inserted into the socket, preventing the separation of the O-ring, and having a support protrusion protruding from the inner circumference at a constant height; and an adhesion member arranged between the O-ring and the grab ring to bring the elastic pieces into contact with the outer surface of the pipe when the screw cap is coupled to the socket, and having an inclined surface. The present invention can improve constructability by enabling the pipes to be easily connected to each other using the grab ring when the pipes are connected, and can improve watertightness by firmly connecting the pipes.
