Description

Slide rail with buffer gear Technical Field The utility model relates to a sliding rail with a buffer mechanism, in particular to a sliding rail which is suitable for a cabinet and a chassis of an industrial server, when one sliding rail is unfolded and folded relative to the other sliding rail, the sliding rail starts to move to a certain distance without resistance, and then a movable mechanism acts to generate a resistance so as to enable the sliding rail to move slowly to a stroke end. Background In the prior art, the rack and cabinet of the industrial server generally comprises a first rail (e.g., an outer frame) and a second rail (e.g., a middle frame or a middle frame and an inner frame), wherein the first rail is mounted on the rack, the second rail is mounted on the cabinet, and when the second rail is moved by an elastic device during the process of expanding and folding relative to the first rail, an elastic force is generated, for example, the elastic device is formed by a spring, so that the second rail has a section of slow displacement travel to the end point by the elastic force of the elastic device before being expanded and folded to the end point of the travel. However, the above-mentioned slow displacement method causes the problem that the second rail is separated from the first rail and the chassis falls out of the cabinet due to the fact that the second rail is repeatedly opposed to the first rail at the moment of starting of the expansion and the retraction of the first rail, i.e. the second rail is provided with a section of starting slow displacement stroke.
