Mutliface-coupling device for hydraulic lines, has blocking device associated with locking sleeve and engaging in region of movement of locking sleeve as blocking element in coupled position of coupling units

摘要

The device has a set of coupling units (1-4) including a plug, a socket (6) for receiving the plug, a self-locking engaging coupling, and a locking sleeve (9) that is moved in relation to the socket. The plug is fixed to one coupling part, and the socket is fixed to another coupling part. A blocking device (18) is moved transversally to the closing and opening direction of the coupling units and is associated with the locking sleeve. The blocking device engages in the region of movement of the locking sleeve as a blocking element in the coupled position of the coupling units.
