The guide rail rebounding buffering damper is matched with a drawer for use, wherein the fixed rail 1 is installed on a drawer groove, and the sliding rail 2 is installed on the drawer, so that the drawer can be in sliding connection with the drawer groove through the guide rail rebounding buffering damper. In the fully opened state of the drawer, the sliding seat 3 is located at the rightmost end of the buffering stroke, and the sliding buckle 8 is located in the stop slot 12 and at the same time located in the sliding stroke of the locking piece 6.

When the drawer needs to be closed, the sliding rail 2 is pushed leftwards, the sliding rail 2 abuts against the rebounding seat 41 to move leftwards, the rebounding tension spring 42 is stretched, and the locking piece 6 is contacted with the sliding buckle 8. The wedge-shaped position of the wedge block 62 drives the sliding buckle 8 to swing, so that the upper column 81 of the sliding buckle 8 enters the arc-shaped gap between the wedge block 62 and the blocking wall 63 and moves along the arc-shaped gap, and meanwhile, the sliding buckle 8 swings integrally and gradually enters the sliding groove 11 from the stop groove 12. Until the upper cylinder 81 moves to the bottom of the arc gap, the upper cylinder 81 is located at the transverse gap between the wedge-shaped block 62 and the blocking wall 63, the sliding buckle 8 completely enters the sliding groove 11, at this time, the force applied to the sliding buckle 8 by the locking member 6 will not drive the sliding buckle 8 to rotate any more, the upper cylinder 81 is "clamped" at the gap between the wedge-shaped block 62 and the blocking wall 63, the locking member 6 is connected with the sliding buckle 8, and the sliding rail 2 and the sliding seat 3 synchronously move leftwards. At this time, the buffer spring 51 is compressed, the sliding seat 3 is buffered and decelerated by the self elastic force, the buffer oil cylinder 52 further buffers and decelerates the sliding seat 3 by the self hydraulic pressure, and finally the sliding seat 3 is stopped at the leftmost end of the buffer stroke and is kept still under the hydraulic pressure of the buffer oil cylinder 52. The process of closing the drawer is completed by buffering and decelerating.

When the drawer needs to be opened, the drawer is pushed leftwards, the sliding rail 2 drives the sliding seat 3 to move leftwards at the moment, the sliding buckle 8 moves leftwards simultaneously, the sliding buckle 8 swings into the avoiding groove 13, and in the process, due to the rotation of the sliding buckle 8, the upper column 81 leaves from the upper side of the arc-shaped gap, so that the sliding buckle 8 is separated from the locking piece 6, and the sliding seat 3 is separated from the sliding rail 2. At this time, the sliding rail 2 and the rebounding base 41 are no longer under the action of the hydraulic force of the buffer cylinder 52, and the rebounding tension spring 42 naturally retracts to enable the rebounding base 41 to move rightwards, so that the sliding rail 2 is pushed to bounce rightwards, and the rebounding opening process of the sliding rail 2 is completed. At this time, the sliding rail 2 is continuously pulled rightwards, when the sliding rail 2 moves until the unlocking part 7 contacts with the sliding buckle 8, the hook-shaped unlocking part 7 hooks the upper column 81, so that the unlocking part 7 is connected with the upper column 81, and the sliding rail 2 and the sliding seat 3 synchronously move rightwards. Until the sliding seat 3 moves to the position stopping groove 12, the sliding buckle 8 swings to enter the position stopping groove 12 to reset, at this time, the upper column 81 is separated from the unlocking piece 7 due to the swing of the sliding buckle 8, so that the sliding seat 3 is separated from the sliding rail 2. At this point the sliding rail 2 can continue to be pulled apart to the right until it is fully opened.
