self-reinforcing door

Abstract

The invention relates to a self reinforcing door body, which comprises a door frame and a door plate, wherein a self reinforcing assembly is also arranged between the door frame and the door plate, and comprises a clamp groove and a rotating shaft; the clamp groove is fixed on the door frame; the rotating shaft is fixed on the door plate; the rotating shaft is clamped in the clamp groove; friction layers are arranged on the outer periphery wall of the rotating shaft and the inner groove wall of the clamp groove; a hydraulic cavity is arranged in the door plate; the hydraulic cylinder communicates with the rotating shaft through a guide pipe, and comprises a hydraulic tube and two piston plates; the piston plates are glidingly arranged in the hydraulic tube; the two piston plates are parallel to the plate surface of the door plate; a tension spring is connected with the two piston plates; a push-pull rod is arranged in a way of penetrating through the two piston plates; the push-pull rod can maintain the reciprocating sliding of a liquid seal relative to the piston plates; and a driving buckle is also arranged on the push-pull rod. The door body structure is novel and unique; the door body opening amplitude can be automatically locked; the wind power closing can be effectively prevented; and convenience is brought to the living life of residents.
