Locking device

The locking device (1) for locking of a container (2), which container has standardized corner castings (20) having an opening (22) in a wall (21), onto a loading surface (3) having a standardized receiving opening (31), wherein the locking mechanism (4) is guided in the standardized receiving opening (31) of the loading surface (3) and projects with a locking head (10), wherein the locking head (10) can engage through the opening (22) and behind the wall (21) of the corner fitting (20) for locking of the container (2) onto the loading surface (3), comprising:

• a grooved bushing (11) provided below the standardized receiving opening (31) of the loading surface (3), in which the locking device (1) is guided retractably in a first position lowered under the loading surface (3) and upon which grooved bushing (11) the locking device (1) is supported projecting above the platform (3) in a second position, and
• a retaining ring (12) which holds the locking device (1) underneath the loading surface (3) in a mounting opening (32) in its first position,
• wherein the locking device (1) comprises a (semi-) automatic locking mechanism (4) in a cylindrical housing (40), wherein the cylindrical housing body is guided by the grooved bushing (11), the assembly opening (32) and the retaining ring (12).
