Synchronization device for drawer slide rail system

Abstract

A synchronizing device of a drawer slide rail system comprises two slide rail subassemblies, wherein the two slide rail subassemblies are arranged on a left side plate of a cabinet and a right side plate of the cabinet; a drawer is arranged on the slide rail subassemblies and consists of a bottom plate and a front panel at least; each slide rail subassembly consists of a movable slide rail and a fixed slide rail at least; synchronizing device bodies for the drawer are arranged on the left movable slide rail and the right movable slide rail or the fixed slide rails; each synchronizing device body comprises a moving piece and a slide cover at least; each movable piece is arranged on the corresponding slide cover and is provided with a rack; gears which are meshed with the slide covers are rotatably arranged on the slide covers and correspond to the racks; the left gear and the right gear are connected with each other through a rotatable connecting rod, so that the left slide rail subassembly and the right slide rail subassembly can be synchronously opened or closed; the drawer is automatically stopped at a position which is distant from a pre-stopping position of the side plates of the cabinet by a distance H through elastic stopping blocks arranged on the movable slide rails or the fixed slide rails when the drawer is closed at least; and the drawer is positioned by elasticity of damping devices arranged on the left movable slide rail and the right movable slide rail or the fixed slide rails. The synchronizing device of the drawer slide rail system has the advantages that the synchronizing device is simple and reasonable in structure, reliable in performance and long in service life; a drawing process is stable and smooth; and a user can draw out the drawer by little force.

Description

technical field [0001] The invention relates to a drawer, in particular to a synchronizing device for a drawer slide rail system. Background technique [0002] Chinese patent document CN101316530A disclosed a drawer on December 3, 2008, which can move from a position in the furniture to a pull-out position in front of the furniture through a pull-out guide device relative to the furniture, wherein the drawer is in the opposite position. There is at least one toothed wheel on each of the opposite sides, which meshes with a toothed rack fixed on the furniture body and is connected with a toothed wheel on the opposite side, each toothed rack can be lengthened via a deflectable rod , thereby also ensuring that the drawer is guided by the gears in the pulled-out position, a deflectable rod can be disengaged from the engaged gears so that the skewed position of the drawer can be corrected, thus ensuring that the drawer is guided by the gears throughout its travel. The structure i...
