Buffering rebound synchronization device

A bottom rail buffer rebound synchronization device, comprising rebound components provided on left and right sides of a drawer and configured to be buckled or separated with a slide rail when the drawer is opened and closed;

• a synchronous linkage assembly configured for a synchronous operation is provided between the rebound components;
• wherein the rebound components include a fixed plate assembly, a toggle block assembly slidably provided on the fixed plate assembly, an elastic sliding assembly, and a synchronous sliding assembly;
• two ends of the synchronous linkage assembly are respectively provided with the synchronous sliding assembly for installation;
• the synchronous sliding assembly is pushed by the elastic sliding assembly to move backward or forward when the drawer is opened and closed;
• the elastic sliding assembly is provided with an elastic stopper,
• the fixed plate assembly is provided with an orienteering protrusion, a fixed plate fixed between the drawer and the slide rail, and a positioning bottom plate provided on the fixed plate,
• a backward guide groove configured for the elastic stopper to be slid backwards in a straight line under a push of the elastic sliding assembly, a separation guide groove configured for compressing the elastic stopper to be separated from the toggle block assembly, a clamping groove position configured for buckling with the elastic stopper, a forward guide groove configured for the elastic stopper to be slid forwards in a straight line under a pull of the elastic sliding assembly in a compressed state, and a reset guide groove configured for the elastic stopper to be reset, ejected and connected with the toggle block assembly are formed by the orienteering protrusion with the fixed plate assembly;
• the elastic sliding assembly is slid in the backward guide groove, the separation guide groove, the clamping groove position, the forward guide groove, and the reset guide groove when the drawer is opened and closed in a cycle manner;
• wherein the elastic sliding assembly comprises a sliding block, a sliding push rod, and a spring, the sliding block is slid forward and backward on the positioning bottom plate, one side of the spring is fastened to the sliding block, the other side of the spring is fastened to the positioning bottom plate, a positioning end shaft of the sliding push rod is connected to the sliding block, the elastic stopper is elastically extended, contracted and connected to the sliding block.
