Background

The sliding rail is usually arranged between the cabinet body and the drawer, and the existing self-interlocking sliding rail can limit that only one drawer can be opened when a plurality of self-interlocking sliding rails are arranged side by side, so that the cabinet body is prevented from toppling over. The self-interlocking sliding rail comprises an outer rail, a locking piece, a sliding rail, an interlocking seat, an interlocking sliding block and a clutch mechanism, wherein the clutch mechanism is used for locking or unlocking the position of the sliding rail relative to the interlocking sliding block. The outer rail extends along the front-back direction, the locking piece slides along the vertical direction and is arranged on the outer rail, the interlocking seat is arranged on the outer rail, and the interlocking sliding block slides and is arranged on the interlocking seat. When a plurality of self-interlocking sliding rails are arranged side by side, two adjacent locking pieces move together.
