Description

Technical Field

[0001] This invention relates to the field of aluminum alloy doors and windows technology, specifically a multifunctional aluminum alloy smoke exhaust window and its construction process. Background Technology

[0002] Smoke exhaust windows are fire protection facilities installed on the exterior walls or roofs of buildings. They are mainly used to remove smoke and heat in a timely manner during a fire, providing favorable conditions for personnel evacuation and fire fighting and rescue. The working principle is generally to open the smoke exhaust window electrically or manually, so as to create convection between indoor and outdoor air, thereby expelling smoke and heat to the outside, providing natural lighting, improving indoor lighting conditions, promoting indoor and outdoor air circulation, and reducing energy consumption for air conditioning and lighting. They are generally classified into electric smoke exhaust windows, manual smoke exhaust windows, and natural smoke exhaust windows.

[0003] Patent No. CN202120916281.0 discloses an automatic smoke exhaust aluminum alloy window with fire-fighting linkage, including a window frame, with matching window sashes and hollow panels arranged sequentially from left to right inside the window frame. An automatic power-off mechanism is installed inside the hollow panel, and matching glass is fixedly installed inside the window sash. A pivot pin is fixedly connected to the outer wall of the window sash near the top, and the pivot pin is rotatably connected to the inner wall of the window frame via a bearing. A servo motor is fixedly installed on the inner wall of the hollow panel, and the output end of the servo motor is fixedly connected via a coupling. It has a pivot, the other end of which passes through the side wall of the hollow board and is fixedly connected to the window sash. The pivot is rotatably connected to the side wall of the hollow board. A smoke sensor is fixedly installed on the inner side of the window frame. The aluminum alloy window can be linked with the fire protection system and can automatically open to exhaust smoke when the indoor smoke concentration exceeds the standard. However, this patent cannot quickly open the aluminum alloy window, so it cannot achieve the smoke exhaust effect immediately. It cannot open and close the aluminum alloy window at large angles multiple times, which reduces the ventilation and smoke exhaust effect. It uses electric window opening and does not have mechanical window opening, which reduces safety.

[0004] Therefore, this invention designs a multifunctional aluminum alloy smoke exhaust window and its construction process to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional aluminum alloy smoke exhaust window and its construction process to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0009] As a further aspect of the present invention: two openings are provided on the upper side of the frame, and fixing buckles are fixedly installed on the lower side of the main window and the secondary window. The end of the fixing buckle away from the main window and the secondary window passes through the opening and is tightly attached to the sliding buckle. A rectangular opening is provided on the lower side of the frame, and a push-pull handle is provided on the rectangular opening. The upper side of the push-pull handle is fixedly installed on the middle side of the rack.

[0010] As a further embodiment of the present invention: the elastic buffer device includes: a sliding rod, a fixed sleeve, a second spring, and a third spring. The sliding rod is rotatably connected to the lower sides of both the main window and the secondary window via a pivot. The fixed sleeve is slidably connected to the sliding rod. The second spring is disposed on the upper side of the fixed sleeve, with its upper side fixedly connected to the upper side of the fixed sleeve and its lower side fixedly connected to the lower side of the sliding rod. The third spring is disposed on the lower side of the fixed sleeve, with its upper side fixedly connected to the lower side of the sliding rod and its lower side fixedly connected to the lower side of the fixed sleeve. The fixed sleeve of the elastic buffer device on the lower side of the secondary window is rotatably connected to the lower side of the frame via a bracket. The fixed sleeve of the elastic buffer device on the lower side of the main window is mounted on the secondary opening and closing device via a bracket.

[0011] As a further embodiment of the present invention: the secondary opening and closing device includes: a semi-circular gear, a second gear, a connecting plate and a driving mechanism. The semi-circular gear is rotatably connected to the lower side of the frame via a rotating shaft, and the second gear is rotatably connected to the lower side of the frame via a rotating shaft. The semi-circular gear and the second gear mesh with each other. The connecting plate is fixedly installed on the side wall of the semi-circular gear. The driving mechanism is installed on the lower side of the frame. The fixing sleeve of the elastic buffer device on the lower side of the main window is rotatably connected to the end of the connecting plate away from the semi-circular gear via a bracket.

[0012] As a further embodiment of the present invention: the driving mechanism includes a drive motor, a worm gear, and a rotating handle. The drive motor is fixedly mounted on the lower side of the frame by a bracket. The worm gear is fixedly mounted on the middle side of the output shaft of the drive motor.

[0013] As a further embodiment of the present invention: an outer frame support frame is fixedly installed on the upper side of the frame, the side wall of the outer frame support frame is provided with a plurality of mounting holes, a protective shell is fixedly installed on the lower side of the frame, and a smoke detector is fixedly installed on the lower side of the protective shell.

[0014] To better achieve the objectives of this invention, the present invention also provides a construction process for a multifunctional aluminum alloy smoke exhaust window, comprising the following steps:

[0015] Step 1: Place the outer frame support frame on the frame into the pre-drilled hole in the roof, and apply waterproof sealant to the contact surface between the outer frame support frame and the roof.

[0016] Step 2: Install the equipment on the roof by passing nails through the multiple mounting holes provided on the side wall of the outer frame support.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention unlocks the main and secondary windows, causing the compressed third spring to return to its original position. This pushes the sliding rod out of the fixed sleeve, allowing it to move upwards and open the main and secondary windows. After the sliding rod moves a certain distance, the third spring is compressed, allowing the sliding rod to pop out quickly while being cushioned by the spring, reducing noise from the rapid opening and closing of the main and secondary windows, extending their service life, and facilitating the rapid pop-out of the main and secondary windows for immediate smoke extraction. The torque motor rotates, driving the first gear, which in turn moves the rack to the left. This movement causes the sliding latch to move to the left, disengaging it from the fixed latch and unlocking the main and secondary windows. Alternatively, moving the push-pull handle to the left moves the rack to the left, which in turn moves the sliding latch to the left, disengaging it from the fixed latch and unlocking the main and secondary windows. This allows for quick manual operation in case of power failure. Release the main and secondary windows from their locked states; the drive motor rotates, causing the worm gear to rotate, which in turn rotates the second gear, which in turn rotates the semi-circular gear, which in turn rotates the connecting plate, which in turn rotates the fixed sleeve. This upward movement of the fixed sleeve, in turn, moves the sliding rod upward, allowing the main window to open significantly again, improving smoke extraction. Alternatively, the main window can be opened and closed a second time by rotating the handle. Rotating the handle rotates the drive motor shaft, which in turn rotates the worm gear, which in turn rotates the second gear, which in turn rotates the semi-circular gear, which in turn rotates the connecting plate, which in turn rotates the fixed sleeve. This upward movement of the fixed sleeve, in turn, moves the sliding rod upward, allowing the main window to open significantly again, facilitating a second, large-angle opening and closing of the main window and improving ventilation and smoke extraction.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] The present invention will be further described below with reference to embodiments.

[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] Example 1: Please refer to Figures 1-7 In this embodiment of the invention, a multifunctional aluminum alloy smoke exhaust window includes a frame 1. A secondary window 2 is hinged to the left side of the frame 1, and a main window 3 is hinged to the right side of the frame 1. Waterproof rubber rings are fixedly installed on the lower sides of both the main window 3 and the secondary window 2. Elastic buffer devices 4 are installed on the lower sides of both the main window 3 and the secondary window 2. A triggering device 5 is installed on the front side of the frame 1, and a secondary opening and closing device 6 is installed on the lower side of the frame 1. The triggering device 5 includes: a guide rail 501, a slider 502, a rack 503, a torque motor 504, a first gear 505, and a buckling mechanism. The guide rail 501 is fixedly installed inside the frame 1. Two sliders 502 are slidably connected to the guide rail 501. The rack 503 is fixedly installed on the side walls of the two sliders 502. The torque motor 504 is fixedly installed inside the frame 1 through a bracket. The first gear 505 is fixedly installed on the output shaft of the torque motor 504. The first gear 505 and the rack 503 mesh with each other. The buckling mechanism is installed on the slider 502.

[0031] The latching mechanism includes a sliding latch 506 and a first spring 507. Each slider 502 is provided with a sliding latch 506 on its upper side. The sliding latch 506 is fixedly installed on the upper side of the slider 502. Each sliding latch 506 is provided with a first spring 507 on its left and right sides. One end of the first spring 507 is fixedly installed on the slider 502, and the other end of the first spring 507 is fixedly installed on the guide rail 501. The first spring 507 is used to buffer the slider 502.

[0032] Two openings are provided on the upper side of the frame 1. Fixing buckles 7 are fixedly installed on the lower side of the main window 3 and the secondary window 2. The end of the fixing buckle 7 away from the main window 3 and the secondary window 2 passes through the opening and is tightly attached to the sliding buckle 506. A rectangular opening is provided on the lower side of the frame 1. A push-pull handle 8 is provided on the rectangular opening. The upper side of the push-pull handle 8 is fixedly installed on the middle side of the rack 503.

[0033] The torque motor 504 rotates, driving the first gear 505 to rotate. The rotation of the first gear 505 drives the rack 503 to move to the left. The leftward movement of the rack 503 drives the sliding latch 506 to move to the left, causing the sliding latch 506 to disengage from the fixed latch 7. This unlocks the main window 3 and the secondary window 2. Alternatively, the push-pull handle 8 can be moved to the left. The push-pull handle 8 moves to the left, driving the rack 503 to move to the left. The leftward movement of the rack 503 drives the sliding latch 506 to move to the left, causing the sliding latch 506 to disengage from the fixed latch 7. This unlocks the main window 3 and the secondary window 2, which is beneficial for manually and quickly unlocking the main window 3 and the secondary window 2 in the event of a power failure.

[0034] The elastic buffer device 4 includes: a sliding rod 401, a fixed sleeve 402, a second spring 403, and a third spring 404. The sliding rod 401 is rotatably connected to the lower side of both the main window 3 and the secondary window 2 via a pivot. The fixed sleeve 402 is slidably connected to the sliding rod 401. The second spring 403 is located on the upper side of the fixed sleeve 402 and is fixedly connected to the upper side of the fixed sleeve 402. The lower side of the second spring 403 is fixedly connected to the lower side of the sliding rod 401. The third spring 404 is located on the lower side of the fixed sleeve 402 and is fixedly connected to the lower side of the sliding rod 401. The lower side of the third spring 404 is fixedly connected to the lower side of the fixed sleeve 402. The fixed sleeve 402 of the elastic buffer device 4 on the lower side of the secondary window 2 is rotatably connected to the lower side of the frame 1 via a bracket. The fixed sleeve 402 of the elastic buffer device 4 on the lower side of the main window 3 is mounted on the secondary opening and closing device 6 via a bracket.

[0035] When the main window 3 and the secondary window 2 are unlocked, the compressed third spring 404 returns to its original state, pushing the sliding rod 401 out of the fixed sleeve 402. This causes the sliding rod 401 to move upward, opening the main window 3 and the secondary window 2. After the sliding rod 401 moves a certain distance, the third spring 404 is compressed, allowing the sliding rod 401 to pop out quickly while being buffered by the third spring 404. This reduces the noise of the rapid opening and closing of the main window 3 and the secondary window 2, extends their service life, and facilitates the rapid pop-out of the main window 3 and the secondary window 2, allowing smoke to be expelled as soon as possible.

[0036] Example 2: As Figure 1-7 As shown, in a preferred embodiment of the present invention, the secondary opening and closing device 6 includes: a semi-circular gear 601, a second gear 602, a connecting plate 603, and a driving mechanism. The semi-circular gear 601 is rotatably connected to the lower side of the frame 1 via a rotating shaft, and the second gear 602 is rotatably connected to the lower side of the frame 1 via a rotating shaft. The semi-circular gear 601 and the second gear 602 mesh with each other. The connecting plate 603 is fixedly installed on the side wall of the semi-circular gear 601. The driving mechanism is installed on the lower side of the frame 1. The fixing sleeve 402 of the elastic buffer device 4 on the lower side of the main window 3 is rotatably connected to the end of the connecting plate 603 away from the semi-circular gear 601 via a bracket.

[0037] The drive mechanism includes a drive motor 604, a worm gear 605, and a rotating handle 606. The drive motor 604 is fixedly mounted on the lower side of the frame 1 by a bracket. The worm gear 605 is fixedly mounted on the middle side of the output shaft of the drive motor 604. The rotating handle 606 is fixedly mounted on the lower side of the output shaft of the drive motor 604. The worm gear 605 and the second gear 602 mesh with each other.

[0038] The drive motor 604 rotates, causing the worm gear 605 to rotate. The worm gear 605 rotates, causing the second gear 602 to rotate. The second gear 602 rotates, causing the semi-circular gear 601 to rotate. The semi-circular gear 601 rotates, causing the connecting plate 603 to rotate. The connecting plate 603 rotates, causing the fixed sleeve 402 to rotate. The rotation of the fixed sleeve 402 causes it to move upward, which in turn causes the sliding rod 401 to move upward, allowing the main window 3 to be opened again at a large angle, improving the smoke extraction effect. The main window 3 can also be opened and closed a second time by rotating the handle 606. Rotating the handle 606 rotates... The rotating shaft of the drive motor 604 rotates, which in turn drives the worm gear 605 to rotate. The rotation of the worm gear 605 drives the second gear 602 to rotate, which in turn drives the semi-circular gear 601 to rotate. The rotation of the semi-circular gear 601 drives the connecting plate 603 to rotate, which in turn drives the fixed sleeve 402 to rotate. The rotation of the fixed sleeve 402 causes the fixed sleeve 402 to move upward, which in turn causes the sliding rod 401 to move upward, allowing the main window 3 to be opened at a large angle again. This facilitates the secondary large-angle opening and closing of the main window 3 and improves the ventilation and smoke extraction effect.

[0039] An outer frame support frame 9 is fixedly installed on the upper side of the frame 1. The outer frame support frame 9 has multiple mounting holes on its side wall. A protective shell 10 is fixedly installed on the lower side of the frame 1. A smoke detector 11 is fixedly installed on the lower side of the protective shell 10.

[0040] The smoke detector 11 detects indoor smoke and transmits an electrical signal to an external controller. The external controller controls the start of the torque motor 504 and the drive motor 604, which facilitates the automatic opening and closing of the main window 3 and the secondary window 2.

[0041] Example 3: As Figure 1-7 As shown in the figure, as a preferred embodiment of the present invention, a construction process for a multifunctional aluminum alloy smoke exhaust window is as follows:

[0042] Step 1: Place the outer frame support 9 on frame 1 into the pre-drilled hole in the roof, and apply waterproof sealant to the contact surface between the outer frame support 9 and the roof.

[0043] Step 2: Install the equipment on the roof by passing nails through the multiple mounting holes provided on the side wall of the outer frame support frame 9.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
