  • the multi-section guide rails in the present disclosure are connected by gear meshing connection, which can realize smooth linkage and reduce the noise and the entire pushing and pulling force during the opening or closing process of the drawer. In such a way, a better experience is achieved.
  • a single-gear guide mechanism for pushing and pulling a drawer includes a fixed rail assembly 1, a movable rail assembly 2 and a middle rail assembly 4.
  • the middle rail assembly 4 is slidably clamped on the fixed rail assembly 1.
  • the movable rail assembly 2 fixedly connecting to a drawer is slidably clamped on the middle rail assembly 4.
  • a sliding assembly is provided in each of a gap between the fixed rail assembly 1 and the middle rail assembly 4 and a gap between the middle rail assembly 4 and the movable rail assembly 2.
  • the movable rail rack 20 is fixed on the movable rail assembly 2.
  • a synchronous gear 40 is rotatably provided on the middle rail assembly 4.
  • the fixed rail rack 10 and the movable rail rack 20 are parallel to each other and are arranged along a sliding direction of the movable rail assembly 2 and the meddle rail assembly 4.
  • the sliding assembly includes an upper ball retainer assembly 3 slidably clamped between the movable rail assembly 2 and the middle rail assembly 4 and a lower ball retainer assembly 5 slidably clamped between the fixed rail assembly 1 and the middle rail assembly 4.
  • Each of a wall of the upper ball retainer assembly 3 and a wall of the lower ball retainer assembly 5 is provided with through holes 30; the through holes 30 are rotatably provided with balls 31 which are in a rolling contact with walls of the movable rail assembly 2 and the middle rail assembly 4 as well as walls of the fixed rail assembly 1 and the middle rail assembly 4.
