Abstract

The invention relates to a drawer sliding track which comprises a fixing sliding track and a movable sliding track. A sliding seat is arranged on the fixing sliding track and is internally provided with an inner chute, a sliding arm and a swinging block; one end of the sliding arm is connected with the swinging block, and the other end of the sliding arm is inserted into the inner chute to slide; the swinging block is provided with an open groove which corresponds to a touch bar arranged on the movable sliding track; the swinging block is connected with one end of an extension spring, and the other end of the extension spring is connected with the sliding seat; the swinging block is provided with a cavity for accommodating a swinging arm; the open groove is formed between one side at one end of the swinging arm and the swinging block; the other side at one end of the swinging arm is elastically connected with the inner wall of the cavity; the other end of the swinging arm is pivoted on the swinging block; the swinging arm is a first swinging arm; the swinging block is provided with a pin shaft; the other end of the first swinging arm is pivoted on the swinging block by the pin shaft; and the cavity is internally provided with an elastic piece, a pressure spring or a torsion spring. The drawer sliding track has the characteristics of simple and reasonable structure, flexible operation, high safety, small sound during opening and closure, long service life and wide application range.

Description

technical field [0001] The invention relates to a drawer slide rail. Background technique [0002] Chinese Patent Document No. CN 200956911 Y disclosed a self-opening device for a drawer slide rail on October 10, 2007. The drawer slide rail includes a fixed slide rail and a moving slide rail. It is equipped with a chute, a sliding arm and a pendulum block. One end of the sliding arm is connected to the pendulum block, and the other end is driven into the chute to slide. The chute includes an inner chute for the sliding arm to slide and an outer slide for the pendulum block to slide. The pendulum block is connected to one end of the spring, the other end of the spring is clamped on the slide seat, and the spring is arranged obliquely in the slide seat; the inner chute is a ring-shaped closed structure, and a positioning block is arranged inside, and one end of the positioning block is provided with a The wavy convex, concave and convex joint surface, the inner chute is set a...
