THREE-SECTION SLIDE MECHANISM

Abstract

The invention relates to a three-link sliding rail mechanism consisting of an outer link (1), a middle link (2), and an inner link (3). The outer rail (11) of the outer link (1) has a sliding surface (111) and an anti-retraction block (114) and a separation block (115) made on the sliding surface (111). The middle rail (21) of the middle link (2) is arranged to slide on the outer rail (11). The anti-retraction device (25) and the driven device (26) are mounted rotating on the end of the middle rail (21). The inner rail (31) of the inner link (3) is arranged to slide on the middle rail (21), and has a support plate (313) and a drive plate (314) made on an inner surface of the inner rail (31). The support plate (313) rests on top of the anti-retraction element (25), and is moved to release the latch from the anti-retraction element (25) to allow the anti-retraction element (25) to rest against the anti-retraction block (114) to prevent the retraction movement of the middle stitch (2) relative to the outer stitch (1).
