QUICKLY DETACHABLE JOINT Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: quick detachable joint has coupling 1 provided with sealing member 12 and nipple 2 interconnected with a locking member constructed as rectangular frame 3 provided with radiused hollows and set in grooves of the coupling. The nipple is provided with a ring groove which defines collars. One of the collars is conical. The frame is provided with wedge parts positioned in the plane facing the conical collar. The beginning of the wedge part is arranged deep within the body of the frame at its lateral axis which passes through the centers of the radiused hollows. The end of the part is positioned in the plane of the frame. When the frame moves, its parts interact with the conical collar of the nipple resulting in forcing its face surface into the coupling and thus pressing a rubber sealing ring. As a result, absolute tightness of the joint is provided. EFFECT: enhanced reliability. 4 dwg
