Laboratory centrifuge with locking system for locking in translation of rotor on driving motor shaft

A laboratory centrifuge comprising:

• two rotating parts, one of the rotating parts being a driving motor shaft and the other of the rotating parts being a rotor, each of the rotating parts having a central longitudinal axis and being provided with complementary assembly devices configured to removably mount said rotor on a free end of said driving motor shaft, coaxially with respect to each other, the assembly devices comprising a locking system for locking in translation of said rotor on said driving motor shaft, the translation locking system comprising
• at least one female element equipping one of said rotating parts, and
• at least one complementary male element equipping the other of said rotating parts, the male element being mobile between an active position in which the male element cooperates with said female element to ensure said locking in translation, and an inactive position in which the male element is separated from said female element, to result in the translation of said rotor with respect to said driving motor shaft,
• the male element being mobile in translation for its operation between the active position and the inactive position,
• the male element being associated with an active-position return device, and an inactive-position operating device for an operation of the male element to the inactive position,
• said inactive-position operating device comprising a rotating actuator member that is carried by one of said rotating parts and that is pivotally mobile about itself according to an axis of rotation extending coaxially to the central longitudinal axis of said associated rotating part, the rotating actuator member cooperating with said male element to ensure, by a rotational operation of said rotating actuator member about its axis of rotation, the displacement of said associated male element from said active position to said inactive position,
• the rotational operation of the rotating actuator member being transformed into a translational movement of the male element between the inactive position and the active position,
• the releasing of the rotating actuator member allowing an automatic return of the male element to the active position, under the effect of the active-position return device that is released.
