A slide rail comprising a mobile rail 1, a middle rail, a fixed rail 3 and a damping mechanism wherein an upper rack and an upper roller cage 6 with a roller are installed between the mobile rail and the middle rail, a split lower roller cage 7 with a roller and a rack is installed between the middle rail and the fixed rail 3, a gear assembly 8.2 is meshed between the two racks and is arranged to provide either synchronous or staggered operation of the rail according to the intensity of force applied. The gear assembly 8.2 may have a polygonal hole which cooperates with a matching column wherein the hole can expand when a sufficient rotating force is applied to allow two gears to slide relative to each other. The rails may be tubular bodies, a buffer plate may be employed and two rails may be arranged either side of a drawer. |
