Abstract:
Disclosed is a hinge, comprising a hinge mount and a hinge shaft. The hinge mount is provided with two hinge cantilevers which are oppositely provided and extend outwardly, free ends of the hinge cantilevers are provided with coaxial pin holes, two ends of the hinge shaft are pivotably inserted into and fixed within the pin holes, a hinge shaft sleeve is sheathed on the hinge shaft, and two ends of the hinge shaft sleeve respectively abut against inner sides of the two hinge cantilevers. An integral shaft sleeve is sheathed on the hinge shaft in the present invention, increasing the contact area between an observation window and the hinge. A hinge reinforcing plate is mounted on an inner frame, increasing the overall rigidity and strength of the observation window, and preventing the observation window from hanging down and hitting the door during long-term use.
