Description

Technical Field

[0001] The utility model relates to the technical field of hardware accessories used between a cabinet body and a door body, in particular to a hinge structure with an opening positioning function. Background Art

[0002] After the existing hinge is opened, the hinge can rotate at will, and the hinge does not have an opening positioning function. In order to solve the above technical problems, Chinese Patent No. ZL201520499050.9 discloses a limited hinge, including a main body, a fixed seat, and a rotating shaft; the main body is provided with a first hinge seat and a second hinge seat, the first hinge seat is provided with a first hinge hole, the second hinge seat is provided with a second hinge hole, and a notch is provided between the first hinge seat and the second hinge seat; the fixed seat is provided with a fixed hinge seat, the fixed hinge seat is provided with a fixed hinge hole, and a first protrusion is provided in the fixed hinge hole; the rotating shaft is provided with a second protrusion corresponding to the first protrusion; the fixed hinge seat is installed at the notch, the rotating shaft is penetrated through the first hinge hole, the fixed hinge hole and the second hinge hole, at least one end of the two ends of the rotating shaft is fixedly connected to the main body, the distance from the radial top of the first protrusion to the axis of the rotating shaft is less than the distance from the radial top of the second protrusion to the axis of the rotating shaft, so that the first protrusion can block the second protrusion in the circumferential direction, thereby limiting the rotation of the rotating shaft, so that the limited hinge can limit the rotation angle when the hinge is opened. Although this hinge structure can limit the rotation angle of the hinge, the hinge can still rotate freely after it is opened. The hinge is opened to the corresponding position angle and the opening of the hinge is limited by the contact between the two protrusions. Therefore, it can only limit the opening angle of the hinge, but cannot position the hinge when it is opened, and cannot fix the opening angle of the hinge. Utility Model Content
