Disclosed is a hinge for a door and a window. The hinge for a door and a window comprises a fixing base (1), a first cantilever (2), a second cantilever (3), a third cantilever (4) and a trailing arm (5). Both ends of the first cantilever (2) and the second cantilever (3) are articulated with the fixing base (1) and the trailing arm (5), respectively. A sliding groove (6) is arranged on the fixing base (1). A sliding block (7) is mounted within the sliding groove (6). One end of the third cantilever (4) is connected to the sliding block (7), and the other end is connected to the second cantilever (3). The two cantilevers, which are fixedly articulated, greatly reinforce the bearing of the hinge and are not easily deformed. The four-bar linkage of the hinge for a door and a window is simple in structure, has a prominent effect, and is convenient to promote. |
