1. A slide rail mechanism adapted for a cabinet, the slide rail mechanism comprising:
a first slide rail assembly arranged on the cabinet, the first slide rail assembly comprising a first rail, a second rail longitudinally displaceable with respect to the first rail, and a self-closing device arranged on the first rail;
a second slide rail assembly arranged on the cabinet, the second slide rail assembly comprising a third rail and a fourth rail longitudinally displaceable with respect to the third rail; and
a connecting member movably mounted on one of the cabinet and the first rail;
wherein the connecting member is moved for preventing the fourth rail from displacing with respect to the third rail along an opening direction when the second rail displaces with respect to the first rail along the opening direction;
wherein the self-closing device comprises a first auxiliary member, a second auxiliary member and a resilient member, the second rail drives the first auxiliary member to resiliently deform the resilient member during a displacement of the second rail with respect to the first rail from a retracted position to an extended position along the opening direction, the second rail is allowed to be driven to the retracted position along a retracting direction by the resilient member when the second rail displaces with respect to the first rail from the extended position along the retracting direction for a predetermined distance, and the second rail drives one of the first auxiliary member and the second auxiliary member to move the connecting member for preventing the fourth rail from displacing with respect to the third rail along the opening direction during the displacement of the second rail with respect to the first rail from the retracted position to the extended position along the opening direction.
