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 to the second hinge seat through a rotating shaft, The fourth articulated rocker arm is articulated with the second articulated rocker arm through a rotating shaft, and the second articulated rocker arm is articulated with the third articulated rocker arm through a rotating shaft. When in use, each articulated rocker arm is hidden in a rocker arm hidden cavity, thereby achieving the effect of hiding the door hinge. However, since this type of door hinge has many articulated parts, the wear generated at each hinge is easily accumulated and superimposed, which easily causes the door hinge to tilt, affecting its use. At the same time, the resistance generated by friction at many places also affects the pushing resistance of the door hinge, and it often requires a lot of force to open and close the door. Summary of the Invention
[0003] The utility model provides a hidden three-dimensional adjustable hinge, which has the advantages of flexible rotation, low resistance and not easy to wear.
[0004] In order to solve the above technical problems, the utility model 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, and one end of the fourth hinge rocker arm is hinged to the second hinge seat through a rotating shaft passing through the corresponding shaft holes on the fourth hinge rocker arm and the second hinge seat On the articulated seat, the other end is hinged to the second articulated rocker arm through a rotating shaft that passes through the corresponding shaft holes on the fourth articulated rocker arm and the second articulated rocker arm respectively. The middle part of the second articulated rocker arm and the middle part of the third articulated rocker arm are hinged to the corresponding shaft holes on the third articulated rocker arm and the second articulated rocker arm respectively through a rotating shaft. A plastic sleeve is provided at each hinge, and the plastic sleeve includes a sleeve part and a cover part. The sleeve part is sleeved between the outer periphery of the rotating shaft and the inner walls of the corresponding shaft holes on the first articulated rocker arm, the second articulated rocker arm, the third articulated rocker arm and the fourth articulated rocker arm, and the cover part is separated between the end faces of the two matching shaft holes. A steel ball hole is provided on the cover part, and a steel ball is provided in the steel ball hole. The diameter of the steel ball is greater than the thickness of the cover part.
[0005] The beneficial effect of the utility model is that by arranging steel balls on the cover part of the shaft sleeve and making the diameter of the steel balls larger than the thickness of the cover part, the rolling friction of the steel balls between the two shaft holes at each hinge can achieve the effect of a ball bearing, thereby achieving the purposes of flexible rotation, low resistance and low wear.
[0006] Furthermore, 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 is matched with the fixing slot, and the mounting hole is matched with the fixing boss. Through the corresponding match between the mounting buckle and the fixing slot on the decorative cover, and the match between the mounting hole and the fixing boss, the decorative cover can be firmly fixed to the first hinge seat and the second hinge seat. At the same time, a reinforced folded edge is provided at a vertical angle to the decorative cover as a whole, which can strengthen the strength of the sheet-shaped decorative cover when the decorative cover is buckled to disassemble the hinge, so that the decorative cover is not easily deformed and is not easily affected in subsequent use.
[0007] 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.
[0008] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
