Description

Technical Field

[0001] This utility model relates to the field of related technologies, and in particular to a single-sided concealed hinge. Background Technology

[0002] Most existing concealed hinges use a multi-link structure to ensure connection stability and smooth rotation. While this structure is complex, it is also relatively expensive. However, for lighter doors or doors where aesthetics are a priority, such a design offers little practical benefit. Therefore, a single-sided concealed hinge with a simple structure, stable connection, and attractive appearance is needed. Utility Model Content

[0003] The main purpose of this utility model is to provide a single-sided concealed hinge that is simple in structure, has a stable connection, and is aesthetically pleasing.

[0004] This utility model proposes a single-sided concealed hinge, including a first hinge body, a second hinge body, a rotating connector, and a rotating connecting rod;

[0005] The top of the first hinge body is provided with a first hinge body connecting groove, and the two rotating connecting parts are fixedly connected to the opposite sides of the first hinge body connecting groove. The rotating connecting rod is rotatably connected between the two rotating connecting parts.

[0006] One end of the second hinge body is fixedly connected to the rotating connecting rod, and the second hinge body can be rotatably connected to the first hinge body connecting groove through the rotating connecting rod.

[0007] Preferably, the top of the first hinge body extends to both sides to form a first hinge body connecting block, and the first hinge body connecting block is provided with a first hinge body connecting hole, through which the first hinge body is connected to the door frame.

[0008] Preferably, the second hinge body is provided with a second hinge body connection hole, and the second hinge body is connected to the door through the second hinge body connection hole.

[0009] Preferably, the rotating connector includes a connector and a rotating component. The rotating component is disposed at the bottom front side of the connector and is fixedly connected to the connector by screws. The rear side of the connector is fixedly connected to the first hinge body by screws.

[0010] Preferably, a rotating component connecting groove is provided on the side of the rotating component opposite to the other rotating component, and the rotating connecting rod is rotatably connected in the rotating component connecting groove.

[0011] Preferably, it also includes a connecting bearing, which is disposed in the connecting groove of the rotating component, and the connecting bearing enables the rotating connecting rod to rotate more smoothly.

[0012] Preferably, the rotating connecting rod is provided with a rotating connecting rod connecting groove adapted to the connecting bearing, and the rotating connecting rod is limited by the rotating component connecting grooves on both sides, and the connecting bearing is limited by the rotating connecting rod connecting groove.

[0013] Preferably, the rotating connecting rod is provided with a rotating connecting rod fixing groove for connecting with the second hinge body.

[0014] The beneficial effects of this utility model's single-sided concealed hinge are:

[0015] 1. By setting a connecting bearing, the second hinge body can rotate more smoothly relative to the first hinge body.

[0016] 2. By using a rotating connector and a rotating connecting rod, the second hinge body can be hidden inside the first hinge body, making the structure relatively simple while the overall appearance is relatively beautiful. Attached Figure Description
