Technical Field

[0001] The utility model relates to a hidden three-dimensional adjustable hinge. Background Art

[0002] Patent No. 201821525681.3, named a hidden door hinge, including a first hinge seat, a second hinge seat, a first hinge rocker arm, a second hinge rocker arm, a third hinge rocker arm and a fourth hinge rocker arm, the first hinge seat and the second hinge seat are both provided with a rocker arm hidden cavity, the first hinge rocker arm is hinged to the first hinge seat through a rotating shaft, the fourth hinge rocker arm is hinged to the second hinge seat through a rotating shaft, the first hinge rocker arm and the third hinge rocker arm are hinged through a rotating shaft, the fourth hinge rocker arm is hinged to the second hinge seat through a rotating shaft, the first hinge rocker arm and the third hinge rocker arm are hinged through a rotating shaft, the fourth hinge rocker arm is hinged to the second hinge seat through a rotating shaft, the fourth hinge rocker arm is hinged to the first hinge seat through a rotating shaft, the fourth hinge rocker arm is hinged to the second hinge seat through a rotating shaft, the fourth hinge rocker arm is hinged to the first hinge seat through a rotating shaft, the fourth hinge rocker arm is hinged to the second hinge seat through a rotating shaft, the first hinge rocker arm and the third hinge rocker arm are hinged ... The four-articulated rocker arm and the second-articulated rocker arm are hinged through a rotating shaft, and the second-articulated rocker arm and the third-articulated rocker arm are hinged through a rotating shaft. When in use, each articulated rocker arm is hidden in the rocker arm hidden cavity, thereby achieving the effect of hiding the door hinge. However, this door hinge has not yet achieved a very good hiding effect. After installing the fastening screws at the mounting block, a decorative cover is still required to cover the mounting block. The traditional decorative cover is a sheet plate with a snap-fit ​​device directly covering the mounting block. The sheet plate is easily bent and deformed during the disassembly and assembly process. Summary of the Invention

[0003] The utility model provides a hidden three-dimensional adjustable hinge, which has the advantages that the decorative cover plate structure is firm and not easily deformed.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a hidden three-dimensional adjustable hinge, comprising a first hinge seat, a second hinge seat, a first hinge rocker arm, a second hinge rocker arm, a third hinge rocker arm and a fourth hinge rocker arm, wherein the outer seat surfaces of the first hinge seat and the second hinge seat are respectively provided with a rocker arm hidden cavity, one end of the first hinge rocker arm is hinged to the first hinge seat through a rotating shaft passing through the first hinge rocker arm and the corresponding shaft holes on the first hinge seat, and the other end is hinged to the third hinge rocker arm through a rotating shaft passing through the corresponding shaft holes on the first hinge rocker arm and the third hinge rocker arm, one end of the fourth hinge rocker arm is respectively passed through the corresponding shaft holes on the fourth hinge rocker arm and the second hinge seat The shaft hole is hinged on the second hinge seat, and the other end is hinged to the second hinged rocker arm through a rotating shaft that passes through the corresponding shaft holes on the fourth hinged rocker arm and the second hinged rocker arm respectively. The middle part of the second hinged rocker arm and the middle part of the third hinged rocker arm are hinged to the corresponding shaft holes on the third hinged rocker arm and the second hinged rocker arm respectively through a rotating shaft. The first hinge seat and the second hinge seat are provided with a mounting seat and a decorative cover, the mounting seat is provided with a fixing boss and a fixing slot, the decorative cover is provided with a mounting buckle and a reinforced folded edge, the mounting buckle is provided with a mounting hole, the reinforced folded edge is at a vertical angle to the decorative cover as a whole, the mounting buckle corresponds to the fixing slot, and the mounting hole corresponds to the fixing boss.

[0005] The beneficial effects of the present invention are as follows: through the corresponding cooperation between the mounting buckle ears and the fixing slots on the decorative cover, and the cooperation between the mounting holes and the fixing bosses, the decorative cover can be firmly fixed to the first hinge seat and the second hinge seat. At the same time, a reinforcing folding edge is provided at a vertical angle to the decorative cover as a whole, which can strengthen the strength of the sheet-like decorative cover when the decorative cover is buckled to disassemble the hinge, making the decorative cover less likely to deform and less likely to affect subsequent use.

[0006] Furthermore, an arc-shaped chamfer is provided on the inner side of the mounting buckle ear. The arc-shaped chamfer can make the decorative cover smoother when buckled, and make it easier for the fixing boss on the mounting buckle ear to fit into the mounting hole.

[0007] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
