A MANUAL LOCKING ASSEMBLY FOR A QUICK CONNECT COUPLING

摘要

The present invention relates to a manual locking assembly for a quick connect coupling (1), wherein, from the outer radius of a cylindrical male pin (2), there extends at least one guiding and retaining lug (3) that during rotation is brought into abutment in corresponding locking grooves (7) within a cylindrical sleeve- shaped female part (6), wherein a centrally in the female part (6), axially arranged rotatable key bolt (10) comprising a quadrilateral locking block (12) that during engagement extends into a corresponding groove (5) in the cylindrical front piece (4) of the male pin (2), the key bolt (10) having a cylindrical guiding flange (13) and a cylindrical locking bolt (11) with millings (11') on opposing sections. The invention is characterized in that a locking bolt retainer (20) has a cylindrical body (21) comprising a lower flange (22) and an upper flange (23), wherein a transversal hole (24) corresponding with the outer radius of the locking bolt (11) is drilled centrally through the body (21), while a groove (25), corresponding with the millings (11') on the locking bolt (11), extends from the hole (24), wherein a spring (27) below the locking bolt retainer (20) is preloaded on locking, and in that the locking bolt retainer (20) on the top side of the upper flange (23) has an inclined surface (26) designed for application of thumb pressure through a hole (9) with associated guiding grooves (8) in the female part (6) for use on unlocking.
