Hidden synchronous guide rail of external side-mounted synchronizer

Abstract

The invention discloses a hidden synchronous guide rail of an external side-mounted synchronizer. The hidden synchronous guide rail comprises an outer rail, a middle rail and an inner rail which are arranged in a sleeving manner successively; an upper ball frame is arranged between the outer rail and the middle rail; a lower ball frame is arranged between the middle rail and the inner rail; ballsor roller pins are arranged on the upper ball frame and the lower ball frame to play a role in supporting the guide rail to slide. The hidden synchronous guide rail is characterized in that an upper rack is fixedly arranged on the outer rail through an upper rack installation plate, the tooth direction of the upper rack is arranged in the horizontal direction, a lower rack is arranged at the bottom of the inner rail through a lower rack installation plate, gears are arranged on the middle rail in a rotating mode, and the gears are meshed with the upper rack and the lower rack. The hidden synchronous guide rail has the beneficial effects that a synchronous mechanism is externally arranged on the outer side wall of each rail, so that the synchronous mechanisms are more convenient to installand maintain in the later period.

Description

technical field [0001] The invention relates to a drawer guide rail, in particular to a hidden synchronous guide rail with an external side-mounted synchronous device. Background technique [0002] Existing drawer slides are generally divided into surface-mounted and concealed. Among them, concealed drawer slides are widely used in furniture drawers, and concealed slides mainly include two-stage and three-stage forms. 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, it is affected by the structural defects between the fixed guide rail, the middle rail and the movable guide rail, which makes the user feel that the drawer is not smooth enough during the push and pull process. , Even the phenomenon tha...

Problems solved by technology

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, it is affected by the structural defects between the fixed guide rail, the middle rail and the movable guide rail, which makes the user feel that the drawer is not smooth enough during the push and pull process. , and even the phenomenon that the slide rail is stuck, which brings great inconvenience to the user

At the same time, the relative position of each section of the multi-section drawer guide rail is random. When the guide rail is fully opened or fully closed, it is pushed by the limit device between each section, resulting in loud noise and stable structure of the guide rail. performance is poor, so it is necessary to make further improvements
