Three-section type hidden sliding rail mechanism

Abstract

The invention provides a three-section type hidden sliding rail mechanism which can solve the problem that sliding rails on the two sides of an existing three-section type hidden sliding rail mechanism are not synchronous in the using process so that using can be affected. The three-section type hidden sliding rail mechanism comprises pairwise sliding rail mechanism bodies which are symmetrically mounted on the left side and the right side of a movable body. Each sliding rail mechanism comprises a fixed guide rail, a middle rail and a movable guide rail. Each fixed guide rail is mounted on a fixed body through a fixed guide rail support, each movable guide rail is mounted on the side face of the movable body through a movable guide rail support, and the fixed guide rails and the movable guide rails are both provided with slippage guide grooves which are in parallel horizontally. The upper ends and the lower ends of the middle rails are mounted in the slippage guide grooves of the movable guide rails and the slippage guide grooves of the fixed guide rails respectively, each middle rail can slip along the slippage guide groove of the corresponding fixed guide rail, and meanwhile each movable guide rail can slip along the corresponding middle rail. The three-section type hidden sliding rail mechanism is characterized in that the sliding rail mechanism bodies on the left side and the right side are connected through a synchronizing mechanism, the synchronizing mechanism comprises rack and pinion mechanisms which are horizontally mounted on the sliding rail mechanism bodies on the left side and the right side in parallel, and the rack and pinion mechanisms on the sliding rail mechanism bodies on the left side and the right side are connected through a connecting shaft.

Description

technical field [0001] The invention relates to a drawer slide rail technology, in particular to a three-stage concealed slide rail mechanism. Background technique [0002] Existing drawer slides are generally divided into two types: surface-mounted and hidden. Among them, hidden drawer slides are widely used in closed objects such as furniture drawers and refrigerator drawers, while hidden slides mainly include two-stage and three-stage There are two types of paragraphs. Most of the existing three-stage concealed slide rails are side buckle type, which are installed symmetrically on both sides of the fixed object and the drawer in pairs. It is located on the side of the drawer, and the movable guide rail and the fixed guide rail are connected through the middle rail. In the actual use process, affected by the gap between the fixed guide rail, the middle rail and the movable guide rail, the slide rails on both sides are prone to sliding out of sync, resulting in the use of ...
