Description

Technical Field

[0001] This invention relates to the technical field of smoke exhaust skylights, specifically to an adjustable installation structure for smoke exhaust skylights. Background Technology

[0002] A skylight is a window installed on the roof, allowing natural light to enter the interior. A smoke exhaust skylight is a type of skylight, a common piece of rooftop fire protection equipment used in factories for ventilation and smoke extraction between the interior and exterior of the building, as well as for lighting and smoke extraction. Smoke exhaust skylights are used for roof ventilation, lighting, and smoke extraction in industrial and civil buildings, primarily in industries such as metallurgy, aviation, shipbuilding, machinery, glass, and light industry, as well as large public buildings. Smoke exhaust skylights enable the rapid removal of excess gas from the building.

[0003] Currently, the window sash and frame of the smoke exhaust skylight are connected by bolts. The frame is pre-fixed to the building. During installation, workers first need to move the window sash onto the frame. To maintain the stability of the window sash and prevent it from shifting during the fixing process, one worker needs to hold the window sash while another worker uses bolts to secure it. However, due to the weight of the window sash, securing it with bolts takes a considerable amount of time. Maintaining the stability of the window sash continuously for an extended period is a significant challenge for the workers. Furthermore, the bolt fixing method requires multiple sets of bolts to be installed one by one, resulting in low installation efficiency. It also requires at least two people to work together and is inconvenient for disassembly during subsequent maintenance and replacement. Summary of the Invention

[0004] The present invention addresses the problem that existing technical solutions are too simplistic by providing a solution that is significantly different from existing technologies. It mainly provides an adjustable installation structure for smoke exhaust skylights to solve the technical problems mentioned in the background.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] An adjustable installation structure for a smoke exhaust skylight includes a frame base fixedly installed on a building and a window sash disposed inside the frame base. The frame base has an annular air chamber inside, and a plurality of limiting grooves are connected to the side of the air chamber facing inward of the frame base. A piston block slides inside each limiting groove. A wedge strip is slidably installed at the center of the piston block. A tenon strip is provided on both sides of the wedge strip. The tenon strip is slidably installed inside the piston block by a limiting spring. Two tenon strips and wedge strips are combined to form a wedge tenon.

[0007] Each piston block has a take-up reel located inside the air chamber on one side. A pull rope is wound on the take-up reel, and the other end of the pull rope is connected to the inside of the piston block. Each take-up reel is equipped with a follower gear connected to the shaft. Several follower gears are connected to each other by a chain.

[0008] The window sash has several sets of mating interfaces for accommodating piston blocks on its frame. Each set of mating interfaces includes two slots. A combination groove for accommodating tenons is connected between the two slots. A central groove for accommodating wedge strips is connected to one side of the combination groove.

[0009] Preferably, the piston block has a sliding cavity at its center, a sliding plug plate slides inside the sliding cavity, the wedge strip is connected to the side of the sliding plug plate facing the inside of the frame seat, and the other end of the pull rope is connected to the sliding plug plate.

[0010] Preferably, the sliding cavity is provided with driving cavities on both sides, and one end of each of the two driving cavities is open to the opposite side. A driving plug plate slides inside each driving cavity. The tenon and the limiting spring are respectively installed on both sides of the driving plug plate, and the other end of the limiting spring is installed on the inner side wall of the driving cavity.

[0011] Preferably, a drive gear is rotatably mounted inside the air chamber, the drive gear meshes with a chain, a shaft is mounted at the center of the drive gear shaft that passes through the air chamber, an air nozzle connected to the air chamber is provided next to the shaft, and a cover plate is provided outside the shaft and the air nozzle.

[0012] Preferably, the drive gear and each follower gear are provided with guide shafts on both sides, and the chain and the guide shafts are in sliding contact.

[0013] Preferably, a blocking block is slidably installed at the opening of the central groove, a push block is installed on one of the tenons, a movable groove for the push block to slide is provided next to the combined groove, and the blocking block is partially located in the movable groove.

[0014] Preferably, the window sash is embedded inside the frame base, and the outer frame of the window sash is located on the inner frame base.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] (1) When installing this smoke exhaust skylight, firstly fit the window sash and the frame base together, then inject air into the air chamber through the air nozzle. As the air pressure inside the air chamber rises, the piston block moves into the slot. Then, the tenon enters the combination groove, allowing the two tenons to meet each other. Next, the wedge strip enters the combination groove. The two tenons and the wedge strip combine to form a tenon and mortise structure like a wedge tenon, which improves the stability of the installation structure between the window sash and the frame base. The whole process only requires the staff to continuously inject air into the air chamber, which greatly improves the installation efficiency. Moreover, it can be completed by one person, reducing the use of labor.

[0017] (2) When installing this smoke exhaust skylight, the window sash and frame base are initially fitted together to ensure the initial stability of the window sash and frame base. There is no need for manual support of the window sash, which improves the installation efficiency. After the window sash and frame base are installed and fixed, the air pressure inside the air chamber is released. This not only avoids the gas inside the air chamber being affected by temperature during use, but also allows the limiting spring to have a restoring pull on the tenon strip, further increasing the structural stability of the combination of the two tenons and wedge strips.

[0018] (3) When this smoke exhaust skylight needs to be disassembled for maintenance or replacement, rotate the shaft to make the drive gear drive the chain to move, and make several follower gears move accordingly. The winding wheel winds up the rope, which drives the sliding stopper plate to move, causing the wedge strip to move and leave the tenon strip. The two tenons are also reset under the pull of the limiting spring and enter the drive cavity. As the sliding stopper plate moves, until the sliding stopper plate and the inner wall of the sliding cavity are in contact, continue to wind up the rope, which will cause the piston block to move and leave the slot, realizing the separation of the window sash and the frame seat. The whole process only requires rotation, which is convenient to use and makes this smoke exhaust skylight easy to maintain and replace later.

[0028] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Please refer to the appendix carefully. Figure 1 and 2This invention provides a technical solution: an adjustable installation structure for a smoke exhaust skylight, comprising a frame base 1 fixedly installed on a building and a window sash 2 disposed inside the frame base 1. The window sash 2 is embedded inside the frame base 1, and the outer frame of the window sash 2 is located on the inner frame of the frame base 1. Embedding the window sash 2 above the frame base 1, so that the outer frame of the window sash 2 is located on the inner frame of the frame base 1, can initially stabilize the window sash 2 and facilitate the installation between the window sash 2 and the frame base 1.

[0032] Please refer to the appendix carefully. Figure 2-7 The frame base 1 has an annular air chamber 11 inside. Several limiting grooves 12 are connected to the side of the air chamber 11 facing inwards from the frame base 1. A piston block 13 slides inside each limiting groove 12. A wedge strip 133 is slidably mounted at the center of the piston block 13. Opposite tenons 137 are provided on both sides of the wedge strip 133. The tenons 137 are slidably mounted inside the piston block 13 by limiting springs 136. Two tenons 137 and wedge strips 133 combine to form a wedge tenon. A sliding cavity 131 is formed at the center of the piston block 13. A sliding stopper plate 132 slides inside the sliding cavity 131. The wedge strip 133 is connected to the side of the sliding stopper plate 132 facing the inside of the frame seat 1. The other end of the pull rope 112 is connected to the sliding stopper plate 132. A driving cavity 134 is provided on both sides of the sliding cavity 131, and one end of each of the two driving cavities 134 is open to the opposite side. A driving stopper plate 135 slides inside each driving cavity 134. The tenon strip 137 and the limiting spring 136 are respectively installed on both sides of the driving stopper plate 135. The other end of the limiting spring 136 is installed on the inner wall of the driving cavity 134. As the air pressure inside the air chamber 11 continues to rise, it will push the piston block 13 to slide inside the limiting groove 12, allowing both ends of the piston block 13 to continuously enter the slot 21. During the movement of the piston block 13, gas will also enter the sliding chamber 131 and the driving chamber 134. However, due to the obstruction of the tenon 137 by the side wall of the slot 21 and the obstruction of the wedge 133 by the blocking block 24, the sliding plug plate 132 and the driving plug plate 135 will not be able to move. Therefore, in the initial stage of the air pressure being injected into the limiting groove 12, only the piston block 13 will move.

[0033] Please refer to the appendix carefully. Figure 2-7The window sash 2 has several sets of mating interfaces for accommodating piston blocks 13 on its frame. Each set of mating interfaces includes two slots 21, and a combination groove 22 for accommodating tenons 137 is connected between the two slots 21. A central groove 23 for accommodating wedge strips 133 is connected to one side of the combination groove 22. A blocking block 24 is slidably installed at the opening of the central groove 23. A push block 26 is installed on one of the tenons 137. A moving groove 25 for the push block 26 to slide is provided next to the combination groove 22. The blocking block 24 is partially located in the moving groove 25. The sliding cavity 131 and the combination groove 22 are opposite each other. Under the push of air pressure, the tenons 137 enter the interior of the combination groove 22, allowing the two tenons 137 to mate with each other. During the movement of the tenons 137, the push block 26 is driven to move. As the push block 26 moves, it pushes open the blocking block 24 at the opening of the central groove 23, allowing the wedge strips 133 to enter the interior of the combination groove 22.

[0034] Please refer to the appendix carefully. Figure 2-4 Each piston block 13 has a take-up reel 111 located inside the air chamber 11 on one side. A pull rope 112 is wound around the take-up reel 111, with the other end of the rope 112 connected to the inside of the piston block 13. Each take-up reel 111 has a follower gear 113 axially connected to its axis. Several follower gears 113 are connected by a chain 114. A drive gear 115 is rotatably mounted inside the air chamber 11, meshing with the chain 114. A shaft 116, penetrating the air chamber 11, is mounted at the axis of the drive gear 115. An air nozzle 118, connected to the air chamber 11, is located beside the shaft 116. A cover plate is provided outside the shaft 116 and the air nozzle 118. An air pump can be used as the air pump connected to the air nozzle. When disassembly is required for maintenance or replacement, rotating shaft 116 causes drive gear 115 to move chain 114, which in turn causes several follower gears 113 to move. Rewind wheel 111 rewinds pull rope 112, which in turn moves sliding stopper plate 132, causing wedge strip 133 to move and disengage from tenon 137. The two tenons 137 are also reset under the pull of limiting spring 136 and enter the drive cavity 134. As sliding stopper plate 132 moves until it is in contact with the inner wall of sliding cavity 131, continuing to rewind pull rope 112 will cause piston block 13 to move and disengage from slot 21, thus separating window sash 2 from frame base 1.

[0035] Please refer to the appendix carefully. Figure 2-4The drive gear 115 and each follower gear 113 are provided with guide shafts 117 on both sides. The chain 114 and the guide shafts 117 are in sliding contact. The presence of the guide shafts 117 is to ensure that the chain 114 and the drive gear 115 or the follower gear 113 have a large contact range, so that the chain 114 can effectively drive the drive gear 115 or the follower gear 113 to rotate.

[0036] The specific operation process of this invention is as follows:

[0037] When installing window sash 2, the workers first manually move window sash 2 and place it above frame base 1. Then, they embed window sash 2 into frame base 1, ensuring the outer frame of window sash 2 is positioned on the inner frame of frame base 1, thus stabilizing window sash 2 initially. Next, the workers open the cover plate and connect the air pump and air nozzle 118. Then, they inject air into the air chamber 11 through the air pump. As the air pressure inside the air chamber 11 continuously increases, it pushes the piston block 13 to slide inside the limiting groove 12, allowing both ends of the piston block 13 to continuously enter the slot 21. During the movement of the piston block 13, gas also enters the sliding chamber 131 and the driving chamber 134. However, due to the obstruction of the tenon 137 by the side wall of slot 21 and the obstruction of the wedge strip 13 by the blocking block 24, the gas is not fully utilized. The obstruction of 3 will prevent the sliding plug plate 132 and the driving plug plate 135 from moving. Therefore, in the initial stage of the air pressure injection into the limiting groove 12, only the piston block 13 will move until the sliding cavity 131 and the combination groove 22 are opposite. Under the push of the air pressure, the tenon 137 will enter the combination groove 22 and the two tenons 137 will be connected to each other. During the movement of the tenon 137, the push block 26 will be driven to move. The push block 26 will push the blocking block 24 at the opening of the center groove 23 to open, so that the wedge strip 133 can enter the combination groove 22. The two tenons 137 and the wedge strip 133 are combined to form a wedge tenon. After that, the air pumping device is removed and the air pressure inside the air chamber 11 is released through the air nozzle 118.

[0038] When disassembly is required for maintenance or replacement, rotating shaft 116 causes drive gear 115 to move chain 114, which in turn causes several follower gears 113 to move. Rewind wheel 111 rewinds pull rope 112, which in turn moves sliding stopper plate 132, causing wedge strip 133 to move and disengage from tenon 137. The two tenons 137 are also reset under the pull of limiting spring 136 and enter the drive cavity 134. As sliding stopper plate 132 moves until it is in contact with the inner wall of sliding cavity 131, continuing to rewind pull rope 112 will cause piston block 13 to move and disengage from slot 21, thus separating window sash 2 from frame base 1.

[0039] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
