Abstract
A waterproof quick coupler which closes a port of a pressure vessel in an air-tight state during a water leakage inspection of a welding portion of the pressure vessel of a compressor. The quick coupler comprises: an outer body having an opening formed at a distal end portion thereof, an inner body flexibly disposed to be rotatable and linearly movable in the outer body; a cap coupled to the distal end portion of the outer body, and a fixing lever flexibly disposed between the inner body and the cap to clamp and unclamp a port of a pressure vessel when the inner body moves forward and backward, wherein the inner body may be locked in the outer body when moving backward, and may be unlocked from the outer body when the outer body rotates in one direction.
