A Three-Dimensional Adjustable Heavy Duty Hidden Hinge

Abstract

The invention provides a three-dimension adjustable heavy-duty concealed hinge. The three-dimension adjustable heavy-duty concealed hinge comprises a door base, a first hinge piece, a second hinge piece, a third hinge piece, a fourth hinge piece and a wall base. The door base and the wall base are provided with a first hinge part and a second hinge part correspondingly. The bottom of the first hinge piece is hinged to the first hinge part of the door base through a knurled rotary shaft. The bottom of the fourth hinge piece is hinged to the first hinge part of the wall base through a knurled rotary shaft. One end of the second hinge piece is hinged to the top of the first hinge part through a knurled rotary shaft. The other end of the second hinge piece is hinged to the second hinge part ofthe wall base through a knurled rotary shaft. The middle of the second hinge piece and the middle of the third hinge piece are hinged through a knurled rotary shaft. The first hinge piece is providedwith an adjusting screw. The three-dimension adjustable heavy-duty concealed hinge provided by the invention adopts a multi-point linkage hinge structure. During installation, the left-right size, the up-down size and the angle of the three-dimension adjustable heavy-duty concealed hinge can be adjusted. The fit dimensions between connecting pieces are accurate. The three-dimension adjustable heavy-duty concealed hinge is large in opening and closing angle and good in stability.

Description

technical field [0001] The invention relates to the technical field of hinges, in particular to a three-dimensionally adjustable heavy-duty hidden hinge. Background technique [0002] At present, the traditional hinge is composed of a fixed page, a movable page and a hinge shaft. The hinge shaft is cylindrical, which runs through the fixed page and the movable page, and makes the fixed page and the movable page form a hinge. The hinge function of this structure is single, and There are only two fixed structures. Under the weight of the door or long-term running-in, the door will sag and can only be opened by itself, and the opening and closing angle is small. In addition, the traditional rotating shaft hinge has a prominent rotating shaft, and the door gap greatly affects the appearance, and the angle and size of the door gap cannot be adjusted. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the present invention proposes a three...
