A drawer slide is arranged for guiding a drawer (2, 4, 6) in an essentially linear movement as the drawer (2, 4, 6) is pulled out from a cabinet (8) to a static extended position (S). The drawer slide comprises at least one drawer biasing member arranged to bias the drawer (2) in a direction towards the cabinet (8) upon pulling the drawer (2, 4, 6) further away from the cabinet (8) beyond the static extended position (S) to a biased non-static extended position (B).

A steel ball retainer locking mechanism of a slide rail includes an engaging block, a release hole, a locking hook, a synchronized hook and a releasing hook. The slide rail includes an outer rail, a steel ball retainer and an inner rail, and the engaging block has a synchronized engaging block and a locking block separated with an interval apart from each other, and the synchronized engaging block has a releasing portion and a synchronized hook portion corresponding to the outer rail and the inner rail respectively, and the locking block has a locking portion and a propping portion corresponding to the outer rail and the inner rail respectively. When the inner rail is pulled outward, the engaging block is locked by the locking hook. After the releasing hook pushes the propping portion, the engaging block is unlocked.

A slide rail self-return mechanism includes a holder base including a base block, a guide plate extended from the base block, a sliding groove defined in the guide plate and abutted to the base block and a mounting groove defined in the guide plate remote from the base block and disposed in communication with the sliding groove, a sliding seat slidably coupled to the holder base, and a biasing member including a body pivotally connected to the sliding seat and a position-limiting block located at the body and movable through the mounting groove into the sliding groove when the sliding seat is coupled to the holder base.

A slide rail assembly includes a first rail, a second rail and a driving mechanism. The second rail is movable relative to the first rail. The second rail includes an engaging feature. The driving mechanism is arranged on the first rail. The driving mechanism includes a housing, a movable member, an actuating structure and an elastic member. The movable member is movable relative to the housing. The actuating structure is arranged on the movable member. The elastic member is configured to provide an elastic force to the movable member. Wherein, the actuating structure includes a first part and a second part. Wherein, the first part is configured to engage with the engaging feature of the second rail, and the second part is configured to prevent the engaging feature of the second rail from being disengaged from the first part.

A refrigerator includes a cabinet defining a compartment, a drawer including a first roller at a rear end of the drawer and a guide rib, a second roller that is located at a front portion of the compartment and supports the guide rib, first roller guides that is located at respective side surfaces of the compartment and defines a movement path of the first roller, and a movable support that supports the drawer from below the drawer and discharges together with the drawer. The guide rib includes a first portion extending from a front of the drawer toward the rear end of the drawer in a direction that slopes downward relative to a bottom surface of the compartment, and each first roller guide includes a rear portion extending rearward in a direction corresponding to a slope of the first portion relative to the bottom surface of the compartment.

A slide rail assembly is configured to mount a chassis to a rack. A plurality of mounting members are arranged at one side of the chassis. The slide rail assembly includes a first rail, a second rail and a guiding base. The second rail includes a side wall and a bottom wall. The guiding base is disposed at a front end of the second rail. The guiding base defines an entry, an exit and a passage located between the entry and the exit. The second rail is moved out of the rack relative to the first rail. The bottom wall of the second rail abuts against a bottom part of the chassis for pushing the chassis into the rack. The chassis is mounted to the second rail through guiding the plurality of mounting members by the entry to pass through the passage and the exit.

A self-closing slide rail assembly includes a first rail, a second rail, and a self-closing mechanism. The second rail is longitudinally displaceable relative to the first rail. The self-closing mechanism includes a housing, an elastic member, and a movable member. The housing is mounted on the first rail. The movable member is movable within the housing in response to the elastic energy released by the elastic member. The second rail is retracted relative to the first rail by the movable member upon engagement therewith when moving from an extended position toward a retracted position.
