[0002] A hinge connects two objects, allowing them to rotate or swing relative to each other. Commonly found in the opening and closing mechanisms of doors, windows, and furniture, existing hinges only serve the function of connecting rotation. For example, the damping hinge with application number CN118911548A includes an outer drive arm, an inner drive arm, and a rebound damping element. The two ends of the outer drive arm are rotatably connected to the cup head and the arm body, respectively. One end of the inner drive arm is rotatably connected to the cup head, and the other end is connected to the moving end of the rebound damping element. The fixed end of the rebound damping element is connected to the arm body. A first drive element and a locking structure are also included. The first drive element is rotatably disposed within the arm body. A protrusion is provided on the first drive element or the cup head. When the cup head is pressed, it abuts against the first drive element through the protrusion. The locking structure is connected to the outer drive arm, and the first drive element is used to unlock the locking structure. When the door is pressed, the protrusion activates the first drive element to unlock the locking structure. The rebound damping element drives the outer and inner drive arms to rotate. Under the combined rotation of the outer and inner drive arms, the cup head rotates and opens. The invention features a hinge with built-in press-and-rebound damping, making it easy to use with concealed doors or handle-less doors.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0031] In one embodiment of this utility model, according to Figure 1-6 As shown, an adjustable hinge includes a first connector 100 and a second connector 200; the first connector 100 and the second connector 200 are connected by a pivot assembly 300, the pivot assembly 300 is hinged to the first connector 100 and the second connector 200, and each end of the second connector 200 is provided with an adjusting member 210, which can adjust the flatness of the hinge and the connected object after installation.

[0032] Specifically, when the first connector 100 and the second connector 200 rotate relative to each other via the pivot assembly 300, the two connected objects can be opened or closed. By setting an adjustment piece 210 on the second connector 200, the flatness of the hinge and the connected objects after installation can be adjusted. If the flatness is insufficient during closing, folding or rotation, targeted adjustments can be made.

[0033] In another embodiment of this utility model, according to Figure 1-3As shown, each adjusting member 210 includes an adjusting hole 211 located at the end of the second connecting member 200; a screw 212 passes through the adjusting hole 211, and the end face of the screw 212 is flat and can abut against the connecting object. Specifically, the screw 212 and the adjusting hole 211 are screwed together, and the flat end face of the screw 212 can abut against the connecting object. By adjusting the depth to which the screw 212 is screwed into the adjusting hole 211, the distance between its mounting part 150 and the connecting object is controlled, thereby adjusting the position of the mounting part 150 so that it can be kept as flush as possible with the surface of the connecting object when embedded in it.

[0034] In another embodiment of this utility model, according to Figure 4 and 5 As shown, both the first connecting member 100 and the second connecting member 200 are provided with mounting grooves 110. Each mounting groove 110 has sliding grooves 120 at both its upper and lower ends. Each mounting groove 110 contains a first connecting post 130. Each first connecting post 130 is installed in the upper and lower sliding grooves 120 and can move within the mounting groove 110. The two ends of the rotating shaft assembly 300 are accommodated in the two mounting grooves 110 and sleeved on the two first connecting posts 130. The rotating shaft assembly 300 includes a first hinge member 310 and a second hinge member 320.

Each mounting portion 150 includes a mounting hole 151; installation is achieved by screws passing through the mounting holes 151. Specifically, the insert portion 160 is mainly used inside the connector, including but not limited to doors and windows, while the mounting portions 150 are used for installation. Connection is achieved by screws inserted into the mounting holes 151. Both the first connector 100 and the second connector 200 have four mounting holes 151, which makes the structure more stable, less prone to loosening, and has a longer service life.
