In the same way, the gear is laterally arranged on the middle rail and is meshed with the upper rack and the lower rack.

When the drawer guide rail opens and closes, when one of them guide rail motion, all can drive other two tracks through the linkage of gear and rack and make equidirectional simultaneous movement for no matter each guide rail is closing or opening the in-process, the motion stroke between two adjacent tracks is unanimous, consequently can effectively guarantee the stability of the support relation between each guide rail, thereby promotes this guide rail bearing capacity. In addition, each guide rail is opened and closed synchronously, so that the guide rails do not frequently impact the limiting stopper in the opening and closing process, the guide rails are opened and closed more smoothly, and the use process of the guide rails is more silent and stable.

Further: the guide rail synchronizing device in the scheme is arranged on the side wall of the guide rail instead of between two adjacent guide rails, so that the size of the synchronizing device can be larger, the synchronizing device with the larger size is convenient to produce and assemble, the shock resistance of the synchronizing device is better, and the service life of the synchronizing device is longer. Meanwhile, the external synchronizer can be conveniently maintained by a user in the later use process, such as dust cleaning, lubricating grease adding and the like, so that the external synchronizer can be widely popularized and used.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof.
