Abstract

A sliding rail device with a buffering function comprises a first sliding rail, a second sliding rail and a buffering unit. The first slide rail includes a first end and a second end opposite to the first end. The second sliding rail is movably arranged on the first sliding rail and comprises a first buffering pushing block and a second buffering pushing block. The buffer unit includes a first buffer assembly disposed at the first end. The second slide rail can move between a folding position and an extending position, when the folding position is reached, the second slide rail is overlapped with the first slide rail and does not protrude out of the first slide rail, the second slide rail can move towards the first end relative to the first slide rail to extend out of the first slide rail to reach the extending position, in the process of moving from the folding position to the extending position, the first buffer push block is abutted against and compresses the first buffer assembly to buffer the second slide rail, and in the process of moving from the extending position to the folding position, the second buffer push block is abutted against and compresses the second buffer assembly to buffer the second slide rail.

Description

Slide rail device with buffering function Technical Field The present disclosure relates to slide rail devices, and particularly to a slide rail device with a buffer function. Background The conventional slide rail device comprises an outer rail, a middle rail and an inner rail. No matter the extension or retraction process, a buffering or decelerating mechanism is needed, so that the middle rail and the inner rail are less prone to damage, and thus there is room for improvement. Disclosure of utility model The present utility model is directed to a slide rail device with a buffering function, which can solve at least one of the above problems. The sliding rail device with the buffering function comprises a first sliding rail, a second sliding rail, a buffering unit and a buffering unit, wherein the first sliding rail comprises a first end and a second end opposite to the first end, the second sliding rail is movably arranged on the first sliding rail and comprises a first buffering pushing block and a second buffering pushing block, the buffering unit comprises a first buffering component arranged at the first end and a second buffering component arranged at the second end, the second sliding rail can move between a folding position and an extending position, when the sliding rail is in the folding position, the second sliding rail is overlapped with the first sliding rail but does not protrude out of the first sliding rail, the second sliding rail can move towards the first end relative to the first sliding rail to extend out of the first sliding rail to reach the extending position, and when the sliding rail is moved from the folding position to the extending position, the first buffering pushing block is abutted against and compressed to enable the second sliding rail to be buffered, and when the sliding rail is moved from the extending position to the folding position, the second buffering component is abutted against and compressed to the second buffering component. In some embodiments, the first sliding rail forms a first buffer slot, and the first buffer assembly includes a first connecting piece disposed in the first buffer slot, a first mounting seat disposed in the first connecting piece, a first cylinder disposed in the first mounting seat and located in the first buffer slot, a first piston rod movably disposed in the first cylinder, and a first push block connected to the first piston rod, where the first push block can abut against the first buffer push block. In some embodiments, the first sliding rail further forms a second buffer slot, and the second buffer assembly includes a second connecting piece disposed in the second buffer slot, a second mounting seat disposed on the second connecting piece, a second cylinder disposed on the second mounting seat and located in the second buffer slot, a second piston rod movably disposed on the second cylinder, and a second push block connected to the second piston rod, where the second push block can abut against the second buffer push block. The first buffer component is arranged at the first end, and the first buffer pushing block is abutted against and compresses the first buffer component to buffer the second slide rail in the process of moving from the folding position to the extending position, so that the first slide rail and the second slide rail can be prevented from being impacted, and the service lives of the first slide rail and the second slide rail can be prolonged.
