Abstract

A drawer sliding rail assembly comprises a fixed sliding rail and a movable sliding rail, a left-right adjusting mechanism is arranged between the fixed sliding rail and the movable sliding rail, the left-right adjusting mechanism comprises a positioning block and a movable block, the movable block is arranged on the positioning block in a sliding mode, an adjusting piece is arranged on the positioning block, and the positioning block and the movable block are connected with the adjusting piece in a matched mode. The movable block slides left and right on the positioning block through the adjusting piece. The left-right adjusting mechanism is independently arranged on the movable sliding rail, and compared with an existing left-right adjusting mechanism between the drawer and the cabinet body, the left-right adjusting mechanism is simpler, lower in cost and easy to assemble. The left-right adjusting mechanism is independently arranged on the movable sliding rail, and compared with an existing left-right adjusting mechanism between the drawer and the cabinet body, the left-right adjusting mechanism is simpler, lower in cost and easy to assemble. On the premise of not changing the assembly (appearance) between the drawer and the sliding rail assembly, the left-right adjusting function of adjusting the left-right gap between the drawer and the cabinet body can be achieved, the product is more attractive and simpler, and the assembly effect is improved.
