Abstract:
1. A slide rail comprising: a first slide comprising a longitudinal bottom wall and a pair of sidewalls extending from two longitudinal sides of the bottom wall; each of the pair of sidewalls providing a first arced surface on its inner side; and a second slide comprising a main plate and two side parts extending from two longitudinal sides of the main plate respectively; each of the two side parts comprising a first curve that provides a second arced surface on its outer side for being engaged with the first arced surface so that the second slide is slidable relative to the first slide, wherein the second arced surface has the same curvature as the first arced surface; each of the two side parts further comprising a second curve providing a fourth arced surface on its inner side, and a first connection portion connecting the first curve and the second curve; extension ends of the two second curves extending away from each other, thereby forming recesses in respective fourth arced surfaces of the second curves; wherein the slide rail further comprises a third slide comprising two arms each providing a third arced surface on its outer side for being slidably contacting with the corresponding fourth arced surface of the second curve; and the two first connection portions extend toward each other, each of the arms of the third slide comprises a clamp plate, the two clamp plates extend toward each other, and extension ends of the two clamp plates are received in the corresponding recesses of the second curves; the extension end of each of the clamp plates is turned over to form a free end, and the free ends are parallel with the corresponding clamp plates.
