Abstract

La présente invention concerne une charnière d'amortissement de porte rabattable, destinée à être utilisée pour résoudre les problèmes selon lesquels un mécanisme d'oscillation de plaque de porte existant présente une faible efficacité de travail et est peu pratique à utiliser. La charnière d'amortissement comprend une plaque fixe de corps principal de charnière qui est montée et fixée verticalement et une plaque de montage de panneau de porte, et comprend en outre un dispositif d'amortissement disposé entre la plaque de montage de panneau de porte et la plaque fixe de corps principal de charnière. Le dispositif d'amortissement comprend une pièce de raccord de liaison de charnière reliée à la plaque de montage de panneau de porte et à la plaque fixe de corps principal de charnière, et un mécanisme d'amortissement pour tirer la pièce de raccord de liaison de charnière pour ouvrir, fermer et faire osciller un panneau de porte. Une glissière de guidage pour amener le panneau de porte à s'ouvrir, se fermer et osciller est disposée sur la plaque fixe de corps principal de charnière. La pièce de raccord de liaison de charnière de la charnière d'amortissement de porte rabattable de la présente invention entraîne la fermeture automatique du panneau de porte dans une glissière de fermeture de la glissière de guidage et l'oscillation dans une glissière d'oscillation. L'angle dans lequel le panneau de porte est automatiquement fermé et l'angle dans lequel le panneau de porte oscille et est ouvert peut être réglé selon les exigences. Le panneau de porte est automatiquement ouvert au maximum dans une glissière d'ouverture sous l'action de la gravité, et est ainsi pratique à utiliser et présente une efficacité de travail élevée.
