  • Publication number: 20250043819
    Abstract: A slide rail assembly includes a first rail, a second rail, an auxiliary member, a blocking member and an operating member. The auxiliary member is arranged on the second rail. The blocking member is pivotally connected to the second rail. When the second rail is located at an extended position relative to the first rail, a blocking feature on the first rail blocks the blocking member in a first state for preventing the second rail from displacing away from the extended position along a retracting direction. When the operating member moves from a first operating position to a second operating position to drive the blocking member to move to a second state, the blocking feature does not block the blocking member in the second state, and the operating member engages with a predetermined portion of the auxiliary member to retain the operating member at the second operating position.
