In this example, the window frame 1, the connecting rod 3 and the plug 7 are all made of an aluminum alloy material. Thus, the bimetal 6 can sense the indoor temperature when a fire occurs better, so that the bimetal 6 can drive the plug pin 7 to be separated from the slot in time, and the window 2 can be closed in time.
When fire does not happen, the bolt 7 is inserted into the slot. The other end of the telescopic assembly 4 is rotatably connected with the side wall of the open slot 8 through the first rotating shaft, and the bolt 7 is inserted into the slot, so that the other end of the telescopic assembly 4 is fixedly connected with the other end of the connecting rod 3. And because the one end of flexible subassembly 4 is articulated with window frame 1, and the one end of connecting rod 3 is articulated with the one end that window 2 kept away from window frame 1, so can adjust the aperture of window 2 through the length of adjusting flexible subassembly 4.

The connecting plates 5 and the bimetallic strips 6 are located in the cavities 9, and the two connecting plates 5 are arranged in parallel.
The deformation temperature of the bimetallic strip 6 is more than 65 degrees and less than 120 degrees, and the bimetallic strip 6 is a snap-type bimetallic disc. Thus, when a fire breaks out in a room, the movable latch 7 can be disengaged from the slot by the bimetal 6.

Thus, the bimetal 6 can sense the indoor temperature when a fire occurs better, so that the bimetal 6 can drive the plug pin 7 to be separated from the slot in time, and the window 2 can be closed in time.
When fire does not happen, the bolt 7 is inserted into the slot. The other end of the telescopic assembly 4 is rotatably connected with the side wall of the open slot 8 through the first rotating shaft, and the bolt 7 is inserted into the slot, so that the other end of the telescopic assembly 4 is fixedly connected with the other end of the connecting rod 3. And because the one end of flexible subassembly 4 is articulated with window frame 1, and the one end of connecting rod 3 is articulated with the one end that window 2 kept away from window frame 1, so can adjust the aperture of window 2 through the length of adjusting flexible subassembly 4.
When a fire breaks out indoors, the bimetallic strip 6 is heated up rapidly. When the temperature of bimetallic strip 6 is greater than the deformation temperature, bimetallic strip 6 is whole to become crooked toward passive layer deformation, and bolt 7 breaks away from in the slot, the other end of flexible subassembly 4 only rotates through the lateral wall of first pivot and fluting 8 to be connected. Because this moment the one end of flexible subassembly 4 is articulated with window frame 1, and the one end that window frame 1 was kept away from to connecting rod 3 and window 2 is articulated, and the other end of flexible subassembly 4 is rotated through the lateral wall of first pivot and fluting 8 and is connected under the 2 self action of gravity of window, flexible subassembly 4 is whole to be close to toward window frame 1, and window 2 self-closing blocks indoor outer circulation of air, prevents that the intensity of a fire from spreading, and indoor flame will extinguish by oneself after oxygen exhausts.
When the indoor fire is extinguished, the temperature of the bimetallic strip 6 is reduced, and the bimetallic strip 6 is restored. The bolt 7 is reinserted into the slot by adjusting the angle between the telescopic assembly 4 and the connecting rod, so that the opening degree of the window 2 can be adjusted by continuously adjusting the length of the telescopic assembly 4.
Through the telescopic assembly 4, the bimetallic strip 6, the connecting plate 5, the bolt 7 and the connecting rod 3, the fireproof window can be automatically closed when a fire disaster happens, so that the fire spread is prevented, and the fireproof window is simple in integral structure and low in cost.

In order to avoid the problem that when a fire occurs, the axis of the piston rod 12 coincides with the axis of the connecting rod 3 and is perpendicular to the window 2, so that the connecting rod 3 and the telescopic assembly 4 are pushed, a stable triangle is formed among the window 2, the window frame 1, the connecting rod 3 and the telescopic assembly 4, and the window 2 cannot be closed under the action of the self gravity, as shown in fig. 1, the telescopic assembly 4 further comprises a baffle plate 14, an elastic film 15, a temperature sensing deformation component 16 and a spine part 17, a circular notch is arranged at the center of the baffle plate 14, the edge of the elastic film 15 is hermetically connected with the circular notch, the edge of the baffle plate 14 is hermetically connected with the inner cavity side wall of the shell 10 and divides the inner cavity of the shell 10 into a first cavity 24 and a second cavity 25, and one end of the temperature sensing deformation component 16 is fixedly connected with the side wall of the second cavity 25 far from, the other end of the temperature sensing deformation component 16 is fixedly connected with a spine part 17, and the spine part 17 is positioned right below the elastic film 15. When the temperature sensitive deformation member 16 has the characteristic of being heated and heated to be elongated, the spine 17 can pierce the elastic film 15 when the temperature sensitive deformation member 16 is heated and elongated.
The temperature sensitive deformation member 16 has a property of being elongated with an increase in temperature. Specifically, the temperature-sensitive deformation member 16 is a cylindrical shape memory alloy or a memory spring having a characteristic of being elongated in its axial direction as its temperature rises.
In this embodiment, the temperature sensitive deformation member 16 is a memory spring, and when a fire occurs, the second memory spring increases in temperature and extends, the spike 17 approaches the elastic membrane 15 and pierces the elastic membrane 15, so that the liquid in the first chamber 24 flows into the second chamber 25 from the gap of the elastic membrane 15. At this time, the telescopic assembly 4 will be contracted under the action of the self-gravity of the window sash, the window 2, the window frame 1, the connecting rod 3 and the telescopic assembly 4 will not be in a stable triangular shape any more, and the window sash will fall and close under the action of the self-gravity.

In this example, the spine portion 17 is a conical spine having a bottom surface diameter larger than the outer diameter of the temperature-sensitive deformation member 16 and smaller than the diameter of the elastic film 15. Thus, when the cone prick pierces the elastic film 15 and completely enters the first chamber 24, the liquid in the first chamber 24 can smoothly flow out from the split of the elastic film 15, and the telescopic assembly 4 can be ensured to be contracted under the action of the gravity of the window 2.
As a preferable technical solution, the lateral surface of the conical spike is further provided with a plurality of grooves parallel to the generatrix direction thereof, so that when the conical spike pierces the elastic membrane 15, the lubricating grease in the first chamber 24 can flow into the second chamber 25 through the grooves.
Example four:
as shown in fig. 1 and 2, an automatic fire window comprises a window frame 1, a window 2, a connecting rod 3 and a telescopic assembly 4, wherein the window 2 is hinged to the top of the window frame 1, one end of the connecting rod 3 is hinged to one end, far away from the window frame 1, of the window 2, the fire window further comprises a connecting plate 5, two metal sheets 6 and a bolt 7, a slot 8 is formed in the other end of the connecting rod 3, one end of the telescopic assembly 4 is hinged to the window frame 1, the other end of the telescopic assembly 4 is hinged to the side wall of the slot 8 through a first rotating shaft, a cavity 9 is formed in the side wall of the slot 8, the connecting plate 5 is provided with two connecting plates, one end of each connecting plate 5 is fixedly connected to the side wall, far away from the slot 8, of the cavity 9, the other end of each connecting plate 5 is fixedly connected to two ends of the metal sheets 6, a passive layer of the metal sheets 6 is located between, one end of the bolt 7 is fixedly connected with the active layer of the bimetallic strip 6, and the other end of the telescopic assembly 4 is provided with a slot matched with the bolt 7.

The deformation temperature of the bimetallic strip 6 is more than 65 degrees and less than 120 degrees, and the bimetallic strip 6 is a snap-type bimetallic disc. Thus, when a fire breaks out in a room, the movable latch 7 can be disengaged from the slot by the bimetal 6.
In this example, the window frame 1, the connecting rod 3 and the plug 7 are all made of an aluminum alloy material. Thus, the bimetal 6 can sense the indoor temperature when a fire occurs better, so that the bimetal 6 can drive the plug pin 7 to be separated from the slot in time, and the window 2 can be closed in time.
When fire does not happen, the bolt 7 is inserted into the slot. The other end of the telescopic assembly 4 is rotatably connected with the side wall of the open slot 8 through the first rotating shaft, and the bolt 7 is inserted into the slot, so that the other end of the telescopic assembly 4 is fixedly connected with the other end of the connecting rod 3. And because the one end of flexible subassembly 4 is articulated with window frame 1, and the one end of connecting rod 3 is articulated with the one end that window 2 kept away from window frame 1, so can adjust the aperture of window 2 through the length of adjusting flexible subassembly 4.
When a fire breaks out indoors, the bimetallic strip 6 is heated up rapidly. When the temperature of bimetallic strip 6 is greater than the deformation temperature, bimetallic strip 6 is whole to become crooked toward passive layer deformation, and bolt 7 breaks away from in the slot, the other end of flexible subassembly 4 only rotates through the lateral wall of first pivot and fluting 8 to be connected. Because this moment the one end of flexible subassembly 4 is articulated with window frame 1, and the one end that window frame 1 was kept away from to connecting rod 3 and window 2 is articulated, and the other end of flexible subassembly 4 is rotated through the lateral wall of first pivot and fluting 8 and is connected under the 2 self action of gravity of window, flexible subassembly 4 is whole to be close to toward window frame 1, and window 2 self-closing blocks indoor outer circulation of air, prevents that the intensity of a fire from spreading, and indoor flame will extinguish by oneself after oxygen exhausts.
When the indoor fire is extinguished, the temperature of the bimetallic strip 6 is reduced, and the bimetallic strip 6 is restored. The bolt 7 is reinserted into the slot by adjusting the angle between the telescopic assembly 4 and the connecting rod, so that the opening degree of the window 2 can be adjusted by continuously adjusting the length of the telescopic assembly 4.
Through the telescopic assembly 4, the bimetallic strip 6, the connecting plate 5, the bolt 7 and the connecting rod 3, the fireproof window can be automatically closed when a fire disaster happens, so that the fire spread is prevented, and the fireproof window is simple in integral structure and low in cost.

By turning the adjusting bolt 11, the position of one end of the adjusting bolt 11 in the first chamber 24 is adjusted, and the volume of the first chamber 24 is adjusted. When one end of the first adjusting bolt 11 moves towards the first chamber 24, the volume of the first chamber 24 becomes smaller, and the first adjusting bolt 11 drives the hydraulic cylinder sleeve 13 and the piston rod 12 to move away from the sealed chamber through the liquid in the sealed chamber. At this point, the telescopic assembly 4 is extended and the window 2 will be opened by the telescopic assembly 4. When the end of the first adjusting bolt 11 moves away from the first chamber 24, the volume of the first chamber 24 increases, and the cylinder sleeve 13 and the piston rod 12 will move towards the sealed chamber under the effect of the window 2 itself. At this point, the telescopic assembly 4 is retracted and the window 2 is closed under its own weight.
Through flexible subassembly 4, can adjust the aperture of window 2 very conveniently, its overall structure is simple, low cost.
The liquid may be grease, and the diameter of the adjusting bolt 11 is larger than the diameter of the piston rod 12. As a preferred solution, the diameter of the adjusting screw 11 is at least twice the diameter of the outermost cylinder sleeve 13. So, through rotating adjusting bolt 11, can quick adjustment the length of flexible subassembly 4 reaches the effect of quick adjustment window 2 aperture.
In order to avoid the problem that when a fire occurs, the axis of the piston rod 12 coincides with the axis of the connecting rod 3 and is perpendicular to the window 2, so that the connecting rod 3 and the telescopic assembly 4 are pushed, a stable triangle is formed among the window 2, the window frame 1, the connecting rod 3 and the telescopic assembly 4, and the window 2 cannot be closed under the action of the self gravity, as shown in fig. 1, the telescopic assembly 4 further comprises a baffle plate 14, an elastic film 15, a temperature sensing deformation component 16 and a spine part 17, a circular notch is arranged at the center of the baffle plate 14, the edge of the elastic film 15 is hermetically connected with the circular notch, the edge of the baffle plate 14 is hermetically connected with the inner cavity side wall of the shell 10 and divides the inner cavity of the shell 10 into a first cavity 24 and a second cavity 25, and one end of the temperature sensing deformation component 16 is fixedly connected with the side wall of the second cavity 25 far from, the other end of the temperature sensing deformation component 16 is fixedly connected with a spine part 17, and the spine part 17 is positioned right below the elastic film 15. When the temperature sensitive deformation member 16 has the characteristic of being heated and heated to be elongated, the spine 17 can pierce the elastic film 15 when the temperature sensitive deformation member 16 is heated and elongated.
The temperature sensitive deformation member 16 has a property of being elongated with an increase in temperature. Specifically, the temperature-sensitive deformation member 16 is a cylindrical shape memory alloy or a memory spring having a characteristic of being elongated in its axial direction as its temperature rises.
In this embodiment, the temperature sensitive deformation member 16 is a memory spring, and when a fire occurs, the second memory spring increases in temperature and extends, the spike 17 approaches the elastic membrane 15 and pierces the elastic membrane 15, so that the liquid in the first chamber 24 flows into the second chamber 25 from the gap of the elastic membrane 15. At this time, the telescopic assembly 4 will be contracted under the action of the self-gravity of the window sash, the window 2, the window frame 1, the connecting rod 3 and the telescopic assembly 4 will not be in a stable triangular shape any more, and the window sash will fall and close under the action of the self-gravity.
Through setting up baffle 14, elastic film 15, temperature sensing deformation part 16 and spine portion 17, can avoid appearing when the conflagration takes place, the axial lead of piston rod 12 and the coincidence of connecting rod 3 axial lead and perpendicular to window 2 and lead to connecting rod 3 and flexible subassembly 4 to die, form a firm triangle-shaped between window 2, window frame 1, connecting rod 3 and the flexible subassembly 4, the problem that window 2 can't close under its self action of gravity.
In this example, the spine portion 17 is a conical spine having a bottom surface diameter larger than the outer diameter of the temperature-sensitive deformation member 16 and smaller than the diameter of the elastic film 15. Thus, when the cone prick pierces the elastic film 15 and completely enters the first chamber 24, the liquid in the first chamber 24 can smoothly flow out from the split of the elastic film 15, and the telescopic assembly 4 can be ensured to be contracted under the action of the gravity of the window 2.
As a preferable technical solution, the lateral surface of the conical spike is further provided with a plurality of grooves parallel to the generatrix direction thereof, so that when the conical spike pierces the elastic membrane 15, the lubricating grease in the first chamber 24 can flow into the second chamber 25 through the grooves.
Because the fire window is opened throughout the year, piston rod 12 and connecting rod 3 receive the solarization and rain to drench and rust easily, piston rod 12 with the connecting rod 3's connection position is also blocked by dust easily to when bolt 7 breaks away from the back from the slot, the card is died between piston rod 12 and the connecting rod 3, can't rotate in a flexible way. Thus, in case of fire, even though the plug 7 is disengaged from the socket, the piston rod 12 and the connecting rod 3 may not be able to rotate smoothly about the first rotation axis by the weight of the window 2, and the window 2 may not be able to close by its own weight.
