Slide rail lock device

A slide rail lock device adapted to be disposed on a slide rail that includes an outer rail and an inner rail which is movable relative to the outer rail, the slide rail lock device comprising:

• a base unit including an outer frame that is adapted to be fixedly connected to the outer rail, a base that is adapted to be fixedly connected to the inner rail, and an inner support frame that is fixedly connected to the base, the outer frame having an outer connection portion that is adapted to be fixedly connected to the outer rail, an engagement portion that extends from the outer connection portion in a direction away from the outer rail, and an eave portion that is connected to the outer connection portion and an upper edge of the engagement portion, one end part of the eave portion that is distal to the outer connection portion being formed with a lock groove, the inner support frame and the base cooperatively defining a movement slot;
• and
• a lock unit including an engagement member that is rotatably disposed on the base unit, a drive member that is connected to the engagement member and that is movably disposed in the movement slot, a lock member that is rotatably disposed on the base unit, and a lock resilient member that is disposed on the inner support frame and that abuts against the lock member, the engagement member having an engagement section that separably engages the engagement portion of the outer frame, the lock member having a lock section that is operable to engage the lock groove, the drive member being operable to move in the movement slot to urge the engagement member to rotate so that the engagement section of the engagement member is disengaged from the engagement portion of the outer frame, thereby allowing the inner rail, the base, and the inner support frame to move relative to the outer rail, the lock resilient member resiliently biasing the lock member upwardly when the inner rail, the base and the inner support frame are moved relative to the outer rail to a position in which the lock section of the lock member is located below the lock groove so that the lock section of the lock member is operable to engage the lock groove.
