Description

Technical Field

[0001] This invention relates to the field of fireproof window technology, and more particularly to fireproof windows with automatic locking devices. Background Technology

[0002] Fire-resistant windows are windows whose fire-resistant glass and frame can meet fire resistance stability and integrity requirements for a certain period of time. They are generally composed of steel frames, steel sashes, and fire-resistant glass. As an important fire protection device, fire-resistant windows are ubiquitous in various buildings, effectively improving the fire resistance of buildings and protecting people's lives and property.

[0003] In the prior art, reference can be made to Chinese Patent Publication No. CN210508909U, which discloses a fireproof window inner frame and a fireproof window, including two symmetrically arranged mounting walls. Each mounting wall has a first mounting groove for mounting a glass frame, a second mounting groove for mounting fixed fireproof glass, and a third mounting groove for mounting a movable window. An isolation section is provided between the second and third mounting grooves. The first and second mounting grooves are arranged sequentially from the interior to the exterior, allowing the fixed fireproof glass to pass through the first mounting groove from the interior and enter the second mounting groove. This fireproof window includes a movable window, fixed fireproof glass, a glass frame, and the aforementioned fireproof window inner frame. The movable window is installed in the third mounting groove, the fixed fireproof glass is installed in the second mounting groove, and the glass frame is installed in the first mounting groove.

[0004] The aforementioned patent has the following shortcomings: it cannot achieve an automatic closing function. In order to prevent flames and smoke from spreading indoors when a fire breaks out outdoors, the fireproof window needs to be closed in time, but it needs to be closed manually, which poses a safety hazard.

[0005] Therefore, the present invention proposes a fireproof window with an automatic locking device. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fireproof window with an automatic locking device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A fireproof window with an automatic locking device includes a window frame and two steel sashes that are movably mounted on the window frame. Fireproof glass is fixedly installed on the inner wall of the steel fan. A second hinge lug is welded to the side wall of the steel fan, and a first hinge lug is welded to the inner side wall of the window frame. The second hinge lug and the first hinge lug are rotatably connected by a connecting shaft. The inner side wall of the window frame is provided with a drive unit for rotating the connecting shaft. The drive unit includes a pneumatic bidirectional telescopic device fixed to the window frame and a heat-conducting gas storage box. The telescopic end of the pneumatic bidirectional telescopic device is driven and coupled to the connecting shaft. The inner cavity of the heat-conducting gas storage box is connected to the drive end of the pneumatic bidirectional telescopic device. The heat-conducting gas storage box stores thermally expanding gas, and a heat insulation cavity is provided on the side of the heat-conducting gas storage box closest to the interior.

[0008] Preferably, the pneumatic bidirectional telescopic device includes a cylinder body one and a cylinder body two welded to one side wall of the cylinder body and communicating with the inner cavity of the cylinder body one. A piston one is slidably connected to the inner wall of the cylinder body one, and a piston rod is fixed to the outer wall of the piston one. The piston rod is driven and engaged with the connecting shaft through a motion conversion component.

[0009] Furthermore, the motion conversion component is used to convert linear motion into rotational motion.

[0010] Based on the aforementioned scheme: a piston is slidably connected to the inner wall of the second cylinder, a spring is fastened to the side wall of the second piston, the other end of the spring is fastened to the inner wall of the second cylinder, and a through hole communicating with the atmosphere is opened on the side wall of the second cylinder, and the second cylinder is connected to the inner cavity of the first cylinder through a connecting pipe.

[0011] A preferred embodiment of the aforementioned solution is that the motion conversion assembly includes a helical groove, a sleeve, and a limiting protrusion. The sleeve is fixed to the end of the piston rod, the helical groove is formed on the side wall of the connecting shaft, and the limiting protrusion is fixed to the inner wall of the sleeve, and the limiting protrusion is movably limited and matched with the helical groove.

[0012] As a further aspect of the present invention: the mating surfaces of the two steel fans are respectively provided with locking member A and locking member B, and locking member A and locking member B can cooperate with each other to lock and unlock.

[0013] Meanwhile, the locking component B includes a cylinder three fixedly embedded in the inner wall of the steel fan, and a sliding plug one slidably connected to the inner wall of the steel fan near the indoor side and a sliding plug two slidably connected to the inner wall of the steel fan near the outdoor side. The opposite sides of the sliding plug one and the sliding plug two are fixed by a connecting column.

[0014] As a preferred embodiment of the present invention: a magnetic block is slidably connected to the other side wall of the steel fan, a plurality of pins are fixed to the end of the magnetic block, and a connecting rod is rotatably connected to the side wall of the connecting column, the other end of the connecting rod being rotatably connected to the side wall of the magnetic block.

[0015] Meanwhile, a button is fixed to the other side wall of the slider by bolts.

[0016] As a preferred embodiment of the present invention, the locking member A includes a magnet that is fixedly embedded in the inner wall of the steel fan and can cooperate with the magnetic block, and a plurality of pin holes that are opened on the side wall of the magnet and can be inserted and cooperated with a plurality of pins.

[0017] The beneficial effects of this invention are as follows: 1. This invention, by setting up a pneumatic bidirectional telescopic device and a heat-conducting gas storage box, can utilize the temperature effect when a fire occurs to realize the automatic rotation and closure of the steel fan. This can, on the one hand, promptly prevent the fire from spreading into the room, and on the other hand, eliminate the need for close-range manual operation, thereby increasing safety.

[0018] 2. This invention, by setting up components such as cylinder body one, cylinder body two, through hole, and connecting pipe, can satisfy the automatic rotation and closing function in the event of a fire, and at the same time, allow the steel fan to rotate freely when there is no fire, thus ensuring the basic function of the "window".

[0019] 3. This invention, by setting up a magnetic block, a magnet, and a pin and a hole, enables the magnetic block and magnet to automatically engage the pin and hole when the steel fan rotates to close, thereby locking the steel fan. At the same time, opening it only requires pressing a button, which increases the convenience of use.

[0020] 4. By setting a second sliding plug, the present invention can also take advantage of the temperature rise characteristics when a fire occurs, combined with the thermal expansion characteristics of gas, to make the latch and the pin hole fit more tightly, thereby making the safety protection of the entire fireproof window better.

[0023] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1: Fireproof window with automatic locking device, such as Figures 1-7 As shown, the window includes a window frame 1 and two steel sashes 3 movably mounted on the window frame 1. Fireproof glass 4 is fixedly mounted on the inner wall of the steel sash 3. A second hinge 9 is welded to the side wall of the steel sash 3. A first hinge 8 is welded to the inner side wall of the window frame 1. The second hinge 9 and the first hinge 8 are rotatably connected by a connecting shaft 10. The inner side wall of the window frame 1 is provided with a drive part 2 for rotating the connecting shaft 10.

[0026] The drive unit 2 includes a pneumatic bidirectional telescopic device 11 fixed to the window frame 1 and a heat-conducting gas storage box 12. The telescopic end of the pneumatic bidirectional telescopic device 11 is driven and coupled to the connecting shaft 10. The inner cavity of the heat-conducting gas storage box 12 is connected to the drive end of the pneumatic bidirectional telescopic device 11. The heat-conducting gas storage box 12 stores thermally expanding gas, and a heat insulation cavity is provided on the side of the heat-conducting gas storage box 12 closest to the room.

[0027] The inner wall of the window frame 1 is fixed with a sealing boss 6 that can contact and cooperate with the steel sash 3.

[0028] When a fire occurs outdoors, the temperature will rise, causing the heat-conducting gas storage box 12 to heat up. The thermally expanding gas in the heat-conducting gas storage box 12 will expand due to the heat and enter the pneumatic bidirectional expansion joint 11. The pneumatic bidirectional expansion joint 11 will be driven by air pressure to rotate the connecting shaft 10, thereby driving the steel fan 3 to close.

[0029] This device, by setting up a pneumatic bidirectional expansion joint 11 and a heat-conducting gas storage box 12, can use the temperature effect when a fire occurs to realize the automatic rotation and closure of the steel fan 3. This can prevent the fire from spreading into the room in time, and also eliminates the need for close-range manual operation, thus increasing safety.

[0030] To solve the driver problem; such as Figure 4 As shown, the pneumatic bidirectional telescopic device 11 includes a cylinder body 13 and a cylinder body 20 welded to the side wall of the cylinder body 13 and communicating with the inner cavity of the cylinder body 13. A piston 16 is slidably connected to the inner wall of the cylinder body 13, and a piston rod 15 is fixed to the outer wall of the piston 16. The piston rod 15 is driven and engaged with the connecting shaft 10 through a motion conversion component 14. The motion conversion component 14 is used to convert linear motion into rotational motion.

[0031] A piston 19 is slidably connected to the inner wall of the second cylinder 20. A spring 18 is fastened to the side wall of the second piston 19. The other end of the spring 18 is fastened to the inner wall of the second cylinder 20. A through hole 21 communicating with the atmosphere is opened on the side wall of the second cylinder 20. The second cylinder 20 is connected to the inner cavity of the first cylinder 13 through a connecting pipe 17.

[0032] When a fire occurs and gas enters the cylinder 20, it first drives piston 19 to move until piston 19 moves to the innermost part of cylinder 20. At this time, piston 19 blocks the through hole 21. At the same time, the connecting part of the connecting pipe 17 and cylinder 20 is connected to the inner cavity of cylinder 20 on the outer part of piston 19. Gas will enter the cavity of cylinder 13 through connecting pipe 17. Piston 16 moves outward under gas pressure, thereby driving the connecting shaft 10 to rotate through motion conversion component 14. When there is no fire, piston 19 is located on the outermost side under the elastic force of spring 18. The inner cavity of cylinder 20 is connected to the atmosphere through through hole 21. At this time, piston 16 can move freely, thereby allowing steel fan 3 to rotate freely.

[0033] This device, by setting up components such as cylinder 13, cylinder 20, through hole 21, and connecting pipe 17, can satisfy the automatic rotation and closing function in the event of a fire, and at the same time, allow the steel fan 3 to rotate freely when there is no fire, thus ensuring the basic function of the "window".

[0034] To solve the problem of motion transition; such as Figure 4 As shown, the motion conversion assembly 14 includes a spiral groove 22, a sleeve 23, and a limiting protrusion 24. The sleeve 23 is fixed to the end of the piston rod 15. The spiral groove 22 is opened on the side wall of the connecting shaft 10. The limiting protrusion 24 is fixed to the inner wall of the sleeve 23, and the limiting protrusion 24 is movably limited and matched with the spiral groove 22.

[0035] When the piston rod 15 moves linearly, it will drive the sleeve 23 to move linearly relative to the connecting shaft 10, thereby driving the connecting shaft 10 to rotate through the cooperation of the spiral groove 22 and the limiting protrusion 24.

[0036] In this embodiment, when a fire occurs outdoors, the temperature will rise, causing the heat-conducting gas storage box 12 to heat up. The thermally expanding gas in the heat-conducting gas storage box 12 expands due to heat and enters the pneumatic bidirectional expansion joint 11. When the gas enters the cylinder 20, it will first drive the piston 29 to move until the piston 29 moves to the innermost side of the cylinder 20. At this time, the piston 29 blocks the through hole 21. At the same time, the connecting part of the connecting pipe 17 and the cylinder 20 is connected to the inner cavity of the cylinder 20 on the outer side of the piston 29. The gas will enter the cavity of the cylinder 13 through the connecting pipe 17. The piston 16 moves outward under the pressure of the gas, thereby driving the connecting shaft 10 to rotate through the motion conversion component 14. When there is no fire, the piston 29 is located on the outermost side under the elastic force of the spring 18. The inner cavity of the cylinder 20 is connected to the atmosphere through the through hole 21. At this time, the piston 16 can move freely, thereby allowing the steel fan 3 to rotate freely.

[0037] Example 2: In order to further solve the security problem, this example makes the following improvements based on Example 1: The mating surfaces of the two steel fans 3 are respectively provided with locking parts A5 and B7, and locking parts A5 and B7 can cooperate with each other to lock and unlock.

[0038] The locking component B7 includes a cylinder body 32 fixedly embedded in the inner wall of the steel fan 3, and a sliding plug 26 slidably connected to the inner wall of the steel fan 3 near the indoor side and a sliding plug 30 slidably connected to the inner wall of the steel fan 3 near the outdoor side. The opposite sides of the sliding plug 26 and the sliding plug 30 are fixed by a connecting post 31.

[0039] A magnetic block 28 is slidably connected to the other side wall of the steel fan 3. Multiple pins 27 are fixed to the end of the magnetic block 28. A connecting rod 29 is rotatably connected to the side wall of the connecting column 31. The other end of the connecting rod 29 is rotatably connected to the side wall of the magnetic block 28.

[0040] A button 25 is fixed to the other side wall of the slider 26 by bolts.

[0041] The locking component A5 includes a magnet 33 that is fixedly embedded in the inner wall of the steel fan 3 and can cooperate with the magnetic block 28, and a plurality of pin holes 34 that are opened on the side wall of the magnet 33 and can be inserted into and cooperate with a plurality of pins 27.

[0042] In this embodiment, when the two steel fans 3 are in the closed state, the two mating surfaces of the steel fans 3 are almost in contact, so that the magnetic block 28 is moved by the magnetic attraction of the magnet 33, and the pin 27 is inserted into the pin hole 34, realizing the automatic locking of the steel fans 3. When it is necessary to open, only the button 25 needs to be pressed. The sliding block 26 is moved by the force of the button 25, which pulls the magnetic block 28 through the connecting rod 29, so that the magnetic block 28 overcomes the magnetic attraction and moves, pulling the pin 27 out of the pin hole 34, thus unlocking the two steel fans 3. At the same time, when a fire occurs outside, the gas on the inner wall of the cylinder 32 on the side of the sliding block 30 will also be heated and expanded, so that the sliding block 30 is subjected to gas pressure. The gas pressure is transmitted to the magnetic block 28 through the connecting rod 29, making the pin 27 fit more tightly with the pin hole 34.

[0043] This device, by setting up a magnetic block 28, a magnet 33, a pin 27, and a pin hole 34, can automatically lock the steel fan 3 by using the magnetic block 28 and the magnet 33 to engage the pin 27 and the pin hole 34 when the steel fan 3 rotates to close. At the same time, it can be opened by simply pressing the button 25, which increases the convenience of use.

[0044] In addition, by setting a sliding plug 30, this device can also take advantage of the temperature rise characteristics when a fire occurs, combined with the thermal expansion characteristics of the gas, to make the latch 27 and the pin hole 34 fit more tightly, thereby making the safety protection of the entire fireproof window better.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
