Hinge mechanism and door assembly

Abstract

The invention discloses a hinge mechanism and a door assembly. The hinge mechanism comprises a door frame, a first hinge piece and a second hinge piece, wherein a door body is rotatably connected to the inner side of the door frame, a strip-shaped notch is formed in the bottom of the door body, a buffer device is arranged at the bottom of the door frame, a rotating plate is fixedly installed on one side of the first hinge piece, a rotating part is fixedly mounted on one side of the rotating plate, and an elastic device is arranged on the inner side of one end of the rotating part. According to the hinge mechanism, through cooperative use of the rotating part, a first rotating rod, a first fixing piece, a first steel ball groove, a first magnetic steel ball body and a sleeve, rolling friction is conducted through the first rotating rod and the first magnetic steel ball body, under the action of magnetism, friction between the door frame and the door body is reduced, noise is reduced when the door is opened or closed, the working efficiency of people is improved, noise generated by friction is reduced to the minimum, noise generated when the door is opened or closed is avoided, and people can have a rest better.

Description

technical field [0001] The invention relates to the field of doors, in particular to a hinge mechanism and a door assembly. Background technique [0002] The structure of the door mainly includes a door frame and a door panel hinged on the door frame, wherein the inner edge of the door frame extends inwards with a sticking edge, which can be used by the door panel to lean against when the door is closed. Most of the door frames and door panels are wood products or metal products; folding doors are mainly composed of door frames, door leaves, transmission parts, rotating arm parts, transmission rods, and orientation devices. This door type can be installed both indoors and outdoors. Each gate has four leaves, two on the side and two on the middle. The frame on one side of the side door leaf is connected with the middle door leaf by a hinge. The upper and lower ends of the stile on the other side of the side door leaf are respectively equipped with upper and lower rotating s...
