Embodiment Construction
[0009]Such asFigure 1-2As shown, a four-bar linkage hinge includes a hinge cup 1, a hinge base 2, a main hinge arm 3 and a driving hinge arm 4 hinged between the hinge cup 1 and the hinge base 2 to form a four-bar linkage mechanism, and a driving drive A torsion spring 5 for swinging of the hinge arm 4 and a damper 6 for buffering the swing of the four-bar linkage mechanism when closing the door. In the present invention, the first cross pin 8 is installed in the hinge base 2 at a certain distance from the hinge axis 7 of the hinge base 2 and the main hinge arm 3, and the torsion spring 5 is sleeved on the first cross pin 8 to drive the hinge arm 4 A second horizontal pin 9 is installed at the reverse extension end, one end of the torsion spring 5 abuts against the hinge base 2, and the other end abuts against the second horizontal pin 9. It can be known that the reverse extension end of the driving hinge arm 4 extends substantially in the direction of the torsion spring 5. When the...

The invention discloses a four-bar linkage hinge. The four-bar linkage hinge comprises a hinge cup, a hinge base, a main hinge arm, a driving hinge arm, a torsional spring and a damper, wherein the main hinge arm and the driving hinge arm are hinged between the hinge cup and the hinge base to form a four-bar linkage mechanism, the torsional spring drives the driving hinge arm to swing, and the damper buffers door closing swing of the four-bar linkage mechanism; a first transverse pin is installed in the hinge base and is a certain distance away from a hinge shaft of the hinge base and a hingeshaft of the main hinge arm; the torsional spring is installed on the first transverse pin in a sleeving mode; a second transverse pin is installed at the reverse extending end of the driving hinge arm; and one end of the torsional spring abuts against the hinge base, and the other end of the torsional spring abuts against the second transverse pin. According to the four-bar linkage hinge, the torsional spring is moved away from the hinge shaft of the hinge base and the hinge shaft of the main hinge arm and installed in the hinge base, the torsional spring does not occupy the length of the main hinge arm any more, and therefore the outer diameter of a hinge shaft sleeve of the main hinge arm can be reduced, the effective overhanging length of the main hinge arm is increased, and the effective overhanging length of the whole hinge arm can be increased.
Description
Technical field[0001]The invention relates to the technical field of hinges, in particular to a four-link hinge.Background technique[0002]The four-link hinge for opening and closing the cabinet door is mainly composed of a hinge seat for fixing the cabinet body, a hinge cup for fixing the cabinet door, and a main hinge arm that is hinged between the hinge cup and the hinge seat to form a four-bar linkage mechanism And a torsion spring that drives the hinge arm, a torsion spring that drives the hinge arm to swing, and a damper that cushions the swing of the four-link mechanism when the door is closed. The main hinge arm mainly plays a supporting role, and the driving hinge arm is mainly used to be driven by the torsion spring to swing, mainly to close the door, and thereby drive the entire four-bar linkage mechanism to close the door. Of course, the torsion spring should also be provided to keep the hinge cup completely The reverse torque of the small opening swing in the open state....
