Abstract
The invention discloses a slide rail, which comprises an upper rail, a middle rail and a lower rail which are mutually in linear sliding fit; an upper and middle rail balance retainer is arranged between the upper rail and the middle rail; at least one first oblique roller arranged obliquely relative to the vertical plane is arranged in the upper and middle rail balance retainer; and the first oblique roller is in rolling fit with the upper rail and the middle rail. By arranging at least one set of first oblique roller arranged obliquely relative to the vertical plane between the upper rail and the middle rail, the rolling fit area between the upper rail and the middle rail is enlarged; and meanwhile, the upper rail and the middle rail are provided with inclined planes corresponding to the first oblique roller, so that the area of encircling the middle rail by the upper rail is enlarged, and the slide rail rocks little during sliding linearly. In addition, when the upper rail and the middle rail incline outwards, partial supporting forces at the tops of the upper rail and the middle rail can be distributed to the inclined planes, so that the service life of the slide rail is prolonged. The slide rail has simple and reasonable structure, slides stably and smoothly, and has strong supporting capacity and low working noise.
