A sliding track assembly including an outer rail securely fixed to the inside wall of a cabinet, an intermediate rail, an rail securely fixed to a drawer at one lateral side, a first sliding ball rack slidably connected between the outer rail and the intermediate rail, and a second sliding ball rack
A sliding track assembly including an outer rail securely fixed to the inside wall of a cabinet, an intermediate rail, an rail securely fixed to a drawer at one lateral side, a first sliding ball rack slidably connected between the outer rail and the intermediate rail, and a second sliding ball rack slidably connected between the intermediate rail and the inner rail, a first stop plate fixed to the intermediate rail at an outer end and having two projecting blocks for engagement with a second stop plate on the inner rail and two stop rods for stopping the second sliding ball rack in place, and a second stop plate fixed to the inner rail at an outer side to engage with the projecting blocks of the first stop plate so as to stop the drawer in place when the drawer is pulled out. The second stop plate has a projecting block at one end fitted into a locating hole on the inner rail, a forked tail fastened to a retainer rod on the inner rail, a retaining portion suspended between the projecting block and the forked tail for engagement with the projecting blocks of the first stop plate, and a press portion connected between the retaining portion and the forked tail and depressed to disengage the retaining portion from the projecting blocks of the first stop plate for allowing the drawer to be disconnected from the cabinet.
