ABSTRACT:
An interlocking mechanism is provided for sliding rails mounted to a cabinet. Each sliding rail comprises an outer rail and an inner rail slidably attached to the outer rail. The interlocking mechanism includes a plurality of interlocking members each of which includes a driving portion and a retaining opening. The interlocking members are respectively attached to the sliding rails. A rod is resiliently and slidably attached to the cabinet. The rod includes a plurality of protrusions and a plurality of corresponding resilient members slantingly attached adjacent to one of the protrusions, corresponding to each interlocking member. The retaining opening comprises a guiding part and a retaining part. If one of the interlocking members moves, the resilient members corresponding to the other interlocking members can move to the corresponding retaining opening retaining parts to lock these interlocking members to prevent the corresponding sliding rails from sliding.
