ABSTRACT:
An instantly-released joint for water conduits comprises a first connector in hollow form with one end coupled to a water conduit, and the other end extruding to form a connecting rod having two locking elements on the top; a second connector in hollow form with one end coupled to a water conduit, and the other end provided with locking holes on the surface, while the inner wall of the second connector without locking holes is provided with grooves extended through outside of the second connector; and a pillar plug having a close end and a free end can operate as a valve. The locking elements of the first connector slide along the grooves of the second connector and are engaged in the locking holes after being turned at a certain angle, such that the two water conduits can be coupled with each other to become a thorough conduit. When turning back the joint at a certain angle, the water conduit assembly would be instantly released.
