Zusammenfassung:A hardware hinge with an external buffer device comprises a hinge cup and a hinge arm, the hinge cup and the hinge arm are hinged through an upper connecting rod and a lower connecting rod, the hinge cup is further provided with the buffer device, the buffer device interacts with the upper connecting rod, and the buffer device plays a role in buffering the closing speed of the hinge when the hinge is closed; the buffering device comprises a shell fixed to the hinge cup, a guide groove is formed in the shell in a hollow mode, a driving sleeve is movably installed in the guide groove, a damping arm is arranged on the cylindrical surface of the driving sleeve in an outward extending mode, a buffer is installed at one end of the driving sleeve, one end of the buffer is borne on the driving sleeve, and the other end of the buffer is borne on the hinge cup. And when the driving sleeve axially displaces, the buffer is compressed to generate damping force. The hinge has the beneficial effects that the damping arm swi
