Until the axial leads of the first connecting rod 3 and the second connecting rod 4 are on the same straight line, the axial lead of the tension spring 7 is parallel to the second connecting rod 4, and the second connecting rod 4 is only stressed on the axial lead, so that the first connecting rod 3 and the second connecting rod 4 are dead against each other, a stable right triangle is formed among the first connecting rod 3, the second connecting rod 4, the window frame 1 and the window 2, and the window 2 is kept in an open state. At this time, the first bimetal 6 is not deformed.

Until the axial leads of the first connecting rod 3 and the second connecting rod 4 are on the same straight line, the axial lead of the tension spring 7 is parallel to the second connecting rod 4, and the second connecting rod 4 is only stressed on the axial lead, so that the first connecting rod 3 and the second connecting rod 4 are dead against each other, a stable right triangle is formed among the first connecting rod 3, the second connecting rod 4, the window frame 1 and the window 2, and the window 2 is kept in an open state. At this time, the first bimetal 6 is not deformed.

When a fire disaster does not happen, the window 2 is pushed open, the hollow pipe 5 rotates around the joint point on the window frame 1, the second connecting rod 4 drives the first connecting rod 3 to rotate, and the window 2 is unfolded around the window frame 1 through the hinge. Until the axial leads of the first connecting rod 3 and the second connecting rod 4 are on the same straight line, the axial lead of the tension spring 7 is parallel to the second connecting rod 4, and the second connecting rod 4 is only stressed on the axial lead, so that the first connecting rod 3 and the second connecting rod 4 are dead against each other, a stable right triangle is formed among the first connecting rod 3, the second connecting rod 4, the window frame 1 and the window 2, and the window 2 is kept in an open state. At this time, the first bimetal 6 is not deformed.
In order to facilitate opening and closing of the window 2, a handle 8 is arranged on the second connecting rod 4, and the tension spring 7 is positioned between the handle 8 and the window frame 1.
The weight of the window 2 differs due to the different profiles. In order to prevent the first bimetal 6 from being deformed and bent by the force component of the total gravity of the window 2, the first connecting rod 3 and the second connecting rod 4 on the axis of the second connecting rod 4 when a stable right triangle is formed among the first connecting rod 3, the second connecting rod 4, the window frame 1 and the window 2, the first bimetal 6 can be two-layer, three-layer, four-layer or multi-layer thermal bimetal according to the weight of the profile of the window 2, and the description of the embodiment is omitted.
In case of fire, the indoor temperature rises, and the high-temperature gas diffuses to the outside through the window 2, thereby causing the window frame 1 and the trigger mechanism. After the first bimetal 6 gradually increases to the operating temperature, the bimetal is entirely bent toward the passive layer 61 side to drive the second connecting rod 4 to move toward the bimetal passive layer 61. At this moment, extension spring 7 length diminishes, extension spring 7's axis and second connecting rod 4 are no longer parallel and the two forms certain contained angle, and then make extension spring 7 pulling second connecting rod 4 and trigger mechanism rotate toward window frame 1 direction around the junction between 1 hollow tube 5 of window frame and the window frame 1, second connecting rod 4 pulling first connecting rod 3 and drive window 2 and rotate to 1 direction of window frame, under extension spring 7 pulling force and the effect of window 2 self gravity, window 2 self-closing blocks indoor outer circulation of air, not only can prevent indoor high temperature gas diffusion, prevent the intensity of a fire from spreading, also can avoid outdoor air to get into indoorly, make indoor flame extinguish by oneself because of oxygen exhausts.
When the indoor flame is extinguished and the indoor temperature is reduced to the reset temperature, the first bimetallic strip 6 is restored to the original shape, and the fireproof window can be opened again for use.
