Technical Field
[0001] This utility model relates to the field of building safety protection equipment technology, and more specifically, to a bottom-mounted explosion vent window capable of venting smoke. Background Technology
[0002] In industrial buildings and other locations with special safety requirements, explosion-proof windows are crucial facilities for protecting lives and property. Under-hung explosion-proof windows, due to their unique opening mechanism, can be used for ventilation under normal circumstances, and can quickly open to release explosion debris and smoke in the event of an explosion.
[0003] Compared to top-hung or casement windows, bottom-hung explosion-proof windows, when open, are more susceptible to wind pressure due to their top-hinged structure. In strong winds or other severe weather conditions, they are prone to swaying or even damage, affecting not only their normal use and lifespan but also potentially interfering with their smoke and explosion-proof functions during an explosion. Therefore, we propose a bottom-hung explosion-proof window capable of smoke extraction. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a bottom-hung explosion relief window that can vent smoke, so as to solve the technical problem that the current bottom-hung explosion relief window, when in the open state, is greatly affected by wind pressure due to its top hinged structure, which makes it prone to shaking or even damage.
[0005] To solve the above technical problems, the present invention provides the following technical solution: a bottom-hung explosion relief window capable of venting smoke, comprising a frame, wherein a plurality of hinges are fixedly provided on one side of the top of the frame, and a flip-up window panel is fixedly connected between the plurality of hinges, and a fixed seat is fixedly provided on both sides of the frame near the window panel, and a telescopic frame that is rotatably connected to the window panel is rotatably installed on the sides of the two fixed seats.
[0006] The telescopic frame includes a fixed component and a movable telescopic component located inside the fixed component. The fixed component has a movable groove on its side wall. The upper and lower sides of the movable groove are extended with sliding grooves to facilitate the movement of the telescopic component. The bottom side of the movable groove has several toothed grooves for limiting the movement. The side of the telescopic component is rotatably mounted with a limiting component that engages with the toothed grooves.
[0007] This utility model enhances the stability of window panels through a unique design of the telescopic frame. The telescopic frame consists of a fixed component and a movable telescopic component. The fixed component has a movable groove on its side wall and sliding grooves on its upper and lower sides to facilitate the movement of the telescopic component. Furthermore, the toothed groove on the bottom side of the movable groove engages with a limiting component rotatably mounted on the side of the telescopic component. This design allows for precise positioning when adjusting the window panel's opening angle through the engagement of the limiting component with different toothed grooves, preventing the window panel from swaying due to wind pressure. When the wind pressure is high, the limiting component firmly engages with the toothed groove, preventing the telescopic component from sliding within the fixed component, thus maintaining a stable opening state of the window panel, avoiding damage caused by shaking, and effectively improving the stability of the window panel's position in high wind conditions.
[0008] Preferably, the limiting member includes a circular plate, one side of which is integrally formed with an extension plate, and the side end of the extension plate is integrally formed with a fixing ring, and a limiting cylinder that engages with the tooth groove is fixedly disposed inside the fixing ring.
[0009] Preferably, the top side of the circular plate has a guide surface, and the included angle of the guide surface is an obtuse angle. The top of the circular plate near the top of the guide surface is also provided with a slanted hook groove.
[0010] Preferably, a first circular block that rotates and engages with a circular plate is fixedly provided on the side of the telescopic member, and a second circular block with the same shape as the first circular block is also fixedly provided at the top position on the same side of the telescopic member. A limit rod is rotatably installed on the outer side of the second circular block, and the side end of the limit rod is constructed with a hook that can engage with the inclined hook groove.
[0011] Preferably, a first circular block that rotates and engages with a circular plate is fixedly provided on the side of the telescopic member, and a second circular block with the same shape as the first circular block is also fixedly provided at the top position on the same side of the telescopic member. A limit rod is rotatably installed on the outer side of the second circular block, and the side end of the limit rod is constructed with a hook that can engage with the inclined hook groove.
[0012] Preferably, slide rails are fixedly installed on both sides of the window panel, and a connector that is movably connected to the slide rails is fixedly installed on the side end of the first circular block.
[0013] Preferably, the fixing member is fixedly provided with limiting grooves on both sides of the opening of the movable groove, and a blocking plate for blocking the movable groove is inserted inside the limiting groove.
[0014] Preferably, the limiting groove has an arc-shaped slot on each of the opposing sides, the bottom sidewall of the baffle has an elastic groove, and the opposing sides of the baffle are fixed with a locking block that engages with the slot.
[0015] Preferably, one end of the movable groove has a bottom side surface with a hooking part for engaging the hook with the oblique hook groove, and the other end of the movable groove has a top side surface with a release part for separating the hook from the oblique hook groove.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This utility model enhances the stability of window panels through the unique design of the telescopic frame. The telescopic frame consists of a fixed component and a movable telescopic component. The fixed component has a movable groove on its side wall and sliding grooves on its upper and lower sides to facilitate the movement of the telescopic component. Furthermore, the toothed groove on the bottom side of the movable groove engages with the limiting component that is rotatably mounted on the side of the telescopic component. This design allows for precise positioning when adjusting the opening angle of the window panel through the engagement of the limiting component with different toothed grooves, preventing the window panel from swinging arbitrarily due to wind pressure. When the wind pressure is high, the limiting component firmly engages with the toothed groove, preventing the telescopic component from sliding within the fixed component, thereby maintaining the stable opening state of the window panel, avoiding damage caused by shaking, and effectively improving the stability of the window panel in high wind environments.
[0018] 2. This utility model also utilizes the guide surface and oblique hook groove of the circular plate, along with the limiting rod and hook, to ensure that when the window panel needs to be closed, the oblique hook groove moves closer to the hook position when the limiting cylinder moves to the hooking part. At the same time, the hook can move upward due to the offset and pressure of the guide surface, thus achieving the effect of locking the two at the appropriate position. This fixes the position of the limiting cylinder, ensuring smooth movement when closing the window panel. When the limiting cylinder moves to the release part, it can be pressed downward, causing the hook to separate from the oblique hook groove, thus releasing the limiting effect. This method makes the opening and closing of the window panel simple and does not require complicated tools or professional skills. Attached Figure Description

[0027] like Figures 1 to 7 As shown, this utility model relates to a bottom-hung explosion-proof window capable of venting smoke, including a frame 1. Several hinges 101 are fixedly provided on one side of the top of the frame 1. A flip-up window panel 2 is fixedly connected between the several hinges 101. Fixed seats 102 are fixedly provided on both sides of the frame 1 near the window panel 2. Telescopic frames 3 that are rotatably connected to the window panel 2 are rotatably installed on the sides of the two fixed seats 102. The position of the window panel 2 is fixed by the hinges 101, which facilitates the bottom-hung flip-up of the window panel 2. The connection of the telescopic frames 3 can increase the support strength of the window panel 2 after it is flipped up.
[0028] The telescopic frame 3 includes a fixing member 4 and a movable telescopic member 5 located inside the fixing member 4. The fixing member 4 has a movable groove 401 on its side wall. The upper and lower sides of the movable groove 401 are both extended with sliding grooves 402 to facilitate the movement of the telescopic member 5. The bottom side of the movable groove 401 has several toothed grooves 403 for limiting. The telescopic member 5 is rotatably mounted on its side and is engaged with the toothed grooves 403. The telescopic member 5 can be easily extended and retracted to adjust its length inside the fixing member 4. The sliding grooves 402 facilitate the displacement of the telescopic member 5. The toothed grooves 403 facilitate the locking of the limiting member 7. When the side end of the limiting member 7 is engaged with the toothed groove 403, it can limit the return and reset of the window panel 2, strengthen the support strength, make the window panel 2 less likely to sway in a strong wind environment, and make the support structure less likely to be damaged.
[0029] In an embodiment of this utility model, the limiting member 7 includes a circular plate 701, an extension plate 702 integrally formed on one side of the circular plate 701, a fixing ring 703 integrally formed on the side end of the extension plate 702, a limiting cylinder 704 fixedly disposed inside the fixing ring 703 and engaging with the toothed groove 403, a guide surface 705 constructed on the top side of the circular plate 701, and the included angle of the guide surface 705 is an obtuse angle, and a slanted hook groove 706 is also provided on the top of the circular plate 701 near the top of the guide surface 705, a first circular block 501 rotatably engaging with the circular plate 701 is fixedly disposed on the side of the telescopic member 5, and the same side of the telescopic member 5... A second circular block 502 with the same shape as the first circular block 501 is fixedly provided at the top position. A limit rod 503 is rotatably installed on the outer side of the second circular block 502. The side end of the limit rod 503 is constructed with a hook 504 that can engage with the oblique hook groove 706. The engagement of the limit cylinder 704 and the tooth groove 403 can achieve the locking effect. When the limit cylinder 704 moves to the top position of the tooth groove 403, the circular plate 701 can be deflected under the limit of the first circular block 501, so that the positions of the guide surface 705 and the oblique hook groove 706 are changed, which can shorten the distance between the hook 504 and the oblique hook groove 706.
[0030] In this embodiment of the utility model, slide rails 201 are fixedly installed on both sides of the window panel 2, and a connector 6 that is movably connected to the slide rails 201 is fixedly installed on the side end of the first round block 501; the connection between the connector 6 and the slide rails 201 can fix the connection position between the telescopic frame 3 and the window panel 2, so as to achieve the effect of movable adjustment.
[0031] In this embodiment of the utility model, the fixing member 4 is fixedly provided with limiting grooves 404 on both sides of the opening of the movable groove 401. A baffle plate 8 for blocking the movable groove 401 is inserted inside the limiting groove 404. The position of the baffle plate 8 can be limited by the limiting groove 404 to block the movable groove 401, prevent dust, debris and other objects from entering the sliding groove 402, avoid affecting the normal movement of the telescopic member 5 and the limiting member 7, and ensure the long-term stable operation of the window panel 2.
[0032] In the embodiments of this utility model, arc-shaped slots 405 are provided on the opposing sides inside the limiting groove 404, and an elastic groove 801 is provided on the bottom side wall of the baffle plate 8. The opposing sides of the baffle plate 8 are fixedly provided with locking blocks 802 that engage with the slots 405. The elastic groove 801 is provided to facilitate the locking blocks 802 to tilt when squeezed, making it easy to engage or separate from the slots 405, thereby improving the installation strength of the baffle plate 8 and facilitating disassembly and assembly.
[0033] In an embodiment of this utility model, a hooking part 4011 for engaging the hook 504 with the oblique hook groove 706 is provided on the bottom side of one end of the movable groove 401, and a release part 4012 for separating the hook 504 from the oblique hook groove 706 is provided on the top side of the other end of the movable groove 401. The hooking part 4011 is an upper inclined surface, which can increase the rotation angle of the circular plate 701 so that the hook 504 can engage with the oblique hook groove 706. The release part 4012 is a lower inclined surface, which can squeeze the circular plate 701 to rotate in the opposite direction, so that the hook 504 disengages from the oblique hook groove 706, achieving the separation effect.
[0034] Working Principle: This embodiment provides a bottom-hung explosion-proof window capable of venting smoke. In use, when the window panel 2 is opened, a pushing force causes the window panel 2 to flip outwards, causing the telescopic frame 3 to flip synchronously. When the moving distance exceeds the length of the telescopic frame 3, it pulls the side telescopic component 5 outwards, thereby causing the limiting component 7, which is rotatably installed on the side of the telescopic component 5, to move synchronously. When the limiting cylinder 704 on the side of the limiting component 7 moves to the position of the toothed groove 403, it automatically engages. Thus, during movement, the limiting cylinder 704 can move up and down along the arc surface of the side of the toothed groove 403 to different positions within the toothed groove 403. The engagement between the limiting cylinder 704 and the toothed groove 403 fixes the window's position after the window's flip angle is fixed, ensuring stability in strong winds and preventing damage. This structural cooperation improves the protection of the connecting window panel 2 structure, making it less susceptible to damage. To close window panel 2, push it outwards to position, causing the limiting cylinder 704 to move to the hooking part 4011. This upward movement causes the circular plate 701 to deflect, bringing the oblique hook groove 706 closer to the hook 504. Simultaneously, the hook 504, pressed by the guide surface 705, automatically moves upwards, engaging with the oblique hook groove 706. This fixes the position of the limiting cylinder 704, eliminating the limiting resistance when pulling back window panel 2 and facilitating resetting. When window panel 2 is closed, the limiting cylinder 704 moves to the release part 4012. The downward pressing force separates the hook 504 from the oblique hook groove 706, releasing the limiting cylinder 704. This ensures automatic limiting when opening window panel 2 again, providing convenient operation. The overall structure effectively improves the ability to open normally during explosion venting.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
