A door hinge assembly is provided. The door hinge assembly includes a first hinge plate, a second hinge plate, one or more bushings, a hinge pin and a hollow sleeve. The first and second hinge plate includes a one or more first and second knuckles aligned axially. At least one of the one or more bushings is positioned in between the first and second knuckle to prevent direct contact of first and second knuckle. The hinge pin is disposed through the first and second knuckles and one or more bushings. The hollow sleeve acts a covering to the hinge pin. The hollow sleeve further prevents contact of the sides of the first knuckle, bushings and second knuckle with the hinge pin. This prevents a direct metal on metal contact and further prevents squeak or other noises occurred during the opening and closing of the door.

A fixing structure of a door body shaft bushing includes a door body outer frame, a door body inner frame engaged with the door body outer frame, a door body shaft bushing arranged between the door body outer frame and the door body inner frame, and a plurality of reinforcing ribs arranged on two opposed surfaces of the door body outer frame and the door body inner frame when the door body outer frame and the door body inner frame are engaged with each other. The plurality of reinforcing ribs are respectively arranged in a staggered manner along a radial direction and an axial direction of shaft holes of the door body shaft bushing. The reinforcing ribs on the door body outer frame and/or the door body inner frame are in contact with the door body shaft bushing and clamp the door body shaft bushing.

A new and improved quiet hinge mechanism assembly comprises first and second hinge plates, and first and second connect plates. A pin shaft passes through the first and second connect plates, and a bushing and gasket are mounted upon the pin shaft such that the first connect plate does not engage the pin shaft, and the first and second connect plates do not engage each other. In addition, the bushing and the gasket are fabricated from a suitable, self-lubricating material, such as, for example, polyoxymethylene (POM), thereby rendering the new and improved hinge mechanism assembly quiet.
