Slide rail assembly

A slide rail assembly comprising:

• a first rail;
• a second rail displaceable relative to the first rail along a longitudinal direction and configured to support a carried object;
• a blocking feature arranged on the first rail;
• an engaging member movable relative to the first rail;
• and
• an auxiliary member configured to be mounted on one of the second rail and the carried object, the auxiliary member comprising a first predetermined portion and a second predetermined portion, the first predetermined portion and the second predetermined portion being perpendicularly connected to each other and respectively extending along the longitudinal direction and a transverse direction perpendicular to the longitudinal direction;
• an operating member movably mounted on the auxiliary member, the operating member being movably switchable between a first state and a second state;
• wherein when the second rail is located at a predetermined position relative to the first rail, the engaging member is blocked by the blocking feature for preventing a displacement of the second rail from a predetermined position along a first direction;
• wherein the operating member is configured to move from the first state to the second state to drive the engaging member, such that the engaging member is not blocked by the blocking feature for allowing the displacement of the second rail from the predetermined position along the first direction;
• wherein the operating member comprises an operating portion, the operating portion of the operating member in the first state extends along the transverse direction and is spaced away from the second predetermined portion of the auxiliary member at a predetermined distance along the longitudinal direction, and when the operating member moves from the first state to the second state, the operating portion of the operating member moves toward the second predetermined portion of the auxiliary member.
