Hinge

The utility model provides a hinge which comprises a first hinge leaf, a second hinge leaf and a buffer damper, a rotor for providing damping buffer is arranged on the buffer damper, and a sleeve is sleeved outside the buffer damper. In the opening and closing process of the hinge, the sleeve extends into the connecting cylinder and partially covers the rotor, so that on the basis of not influencing the rotation of the hinge shaft, when the supporting cylinder and the connecting cylinder generate a transverse shearing acting force due to large-force pulling of the hinge, the supporting cylinder and the connecting cylinder can be separated from each other; the rotor is partially covered by the sleeve, so that the sleeve can replace the rotor to bear shearing acting force, the rotor is protected, damage or disability of the rotor part is avoided, and the reliability of the damping function of the whole hinge is improved. 本实用新型提供一种铰链，包括第一铰链页片、第二铰链页片和缓冲阻尼器，所述缓冲阻尼器上设有提供阻尼缓冲的转子，在所述缓冲阻尼器外套接有套筒。本申请在铰链开合的过程中，由于套筒沿伸入连接
