| 摘要 |
The invention relates to a locking system which comprises a male cylindrical end (12) and a female tubular cylindrical end (16) inside of which the male cylindrical end (12) is to be inserted for coupling. A locking groove (24) is provided in the outer surface (20) of the male cylindrical end (12). In addition, the female tubular cylindrical end (16) is bored on the side with a through-opening (28) inside of which a mobile locking element (30), which projects inside the female tubular cylindrical end (16) and into the locking groove (24) of the male cylindrical end (12), is arranged. Finally, a locking ring (36) is mounted such as to rotate freely on the outer surface of the female tubular cylindrical end (16) opposite the through-opening (28), said ring (36) having an inner surface (40) in which a recess (42) having an orthoradially variable depth enables the locking/unlocking of the mobile locking element (30) against the locking groove (24), depending on the position of the ring. The locking groove (24) also extends in the axial direction (z) of the male cylindrical end (12) from a free end thereof, in order to guide and angularly limit the insertion of the male cylindrical end (12) in the female tubular cylindrical end. |
