Abstract

La présente invention concerne un rail de coulissement et une armoire d'équipement. Le rail de coulissement comprend un rail, un support de boucle rotatif et un support de limitation de boucle. Le rail comprend un corps principal et une partie d'extrémité. Le support de boucle rotatif comprend une partie de montage, une partie de butée et un crochet. La partie de montage est reliée de manière rotative au corps principal, la partie de butée est située à une extrémité de la partie de montage et est pliée et étendue par rapport à la partie de montage, et le crochet est disposé sur la partie de montage dans une configuration en saillie. La structure de limitation de boucle est pourvue d'un trou de bouclage dans une configuration en coulissement, est reliée de façon élastique à la partie élastique et de façon coulissante au corps principal. La rotation du support de boucle rotatif par rapport au corps principal peut actionner le crochet pour le mettre en correspondance avec le trou de bouclage afin d'amener la structure de limitation de boucle à se déplacer horizontalement. Sous l'action de la partie élastique, le crochet et la structure de limitation de boucle sont mis en correspondance pour obtenir un état de verrouillage. Dans l'état de verrouillage, la partie de butée est située sur le côté de la partie d'extrémité à l'opposé du corps principal, et un espace est formé entre la partie de butée et la partie d'extrémité, de telle sorte qu'une installation sans outil du rail de coulissement est réalisée.
