Description

Technical Field

[0001] The invention belongs to the technical field of curtain walls, and in particular relates to a curtain wall smoke exhaust window. Background Art

[0002] With the development of the construction industry, floors are gradually getting higher, and buildings need to reduce their own weight. Glass curtain walls are also often used in building decoration. The installation of curtain walls requires better sealing, which will block the air circulation between indoor and outdoor spaces.

[0003] During some curtain wall installation operations, smoke exhaust windows are installed on the curtain walls. However, common smoke exhaust windows have a small opening angle and poor ventilation effect. In response to the above technical problems, a Chinese patent with patent announcement number CN218029794U has a swing component that can adjust the opening angle of the smoke exhaust window at a large angle to improve the ventilation effect. However, when in use, the swing component needs to be driven by a linear drive component to open the smoke exhaust window, which reduces the opening speed of the smoke exhaust window. In addition, since the linear drive component is arranged above the opening of the smoke exhaust window, the smoke will contact the linear drive component during smoke exhaust. The smoke carries a large amount of heat that will heat the equipment, thereby causing damage to the equipment and reducing the stability of smoke exhaust. Summary of the invention

[0004] The object of the present invention is to provide a curtain wall smoke exhaust window, aiming to solve the technical problems in the prior art that the smoke exhaust window has a slow opening speed and the equipment is easily damaged, reducing the smoke exhaust stability.

[0005] The present invention is implemented as follows: a curtain wall smoke exhaust window comprises a shell, wherein the shell is frame-shaped and a frame-shaped partition is fixedly installed inside the shell, a smoke exhaust window body is rotatably installed in the shell via a first mounting shaft, the first mounting shaft is located at one end of the smoke exhaust window body and is in full contact with the partition when the smoke exhaust window body is rotated to a vertical state, a telescopic member for driving the smoke exhaust window body to rotate is provided in the shell, a guide plate is rotatably installed in the shell via a second mounting shaft, the second mounting shaft is located at one end of the guide plate and is in full contact with the partition when the guide plate is in a vertical state, the guide plate and the smoke exhaust window body are located on both sides of the partition and the first mounting shaft and the second mounting shaft are located at both ends of the shell, and the first mounting shaft and the second mounting shaft are rotatably connected.

[0006] Further technical solution: the telescopic part is fixedly installed in the shell and the telescopic part is eccentrically perpendicular to the first installation axis, a rack is fixedly installed at the output end of the telescopic part, the rack is meshed with a gear fixedly installed on the first installation axis, and the gear is coaxially arranged with the first installation axis.

[0007] Further technical solution: an L-shaped baffle is fixedly installed in the shell, and the telescopic member is located in the baffle.

[0008] Further technical solution: First grooves are formed on both sides of the housing. Both ends of the first mounting shaft and the second mounting shaft extend into the first grooves. First synchronous pulleys are fixedly installed at both ends of the first mounting shaft, and second synchronous pulleys are fixedly installed at both ends of the second mounting shaft. The first synchronous pulley and the second synchronous pulley on the same side are jointly rotatably connected by a synchronous belt.

[0009] Further technical solution: Two groups of symmetrically distributed second grooves are formed on the side surface of the housing close to the smoke exhaust window body. The first mounting shaft passes through the second grooves. An auxiliary support frame is fixedly installed on the first mounting shaft. One end of the auxiliary support frame away from the first mounting shaft is fixedly connected to the side surface of the smoke exhaust window body. A connection port for the auxiliary support frame to enter is formed on the side wall of the second groove.

[0010] Further technical solution: A steel wire rope is arranged on the auxiliary support frame. Both ends of the steel wire rope are fixedly connected to one end of the auxiliary support frame away from the first mounting shaft. Two guide shafts are fixedly installed in the second groove. The guide shafts are located at both ends of the second groove. The steel wire rope is wound around the two guide shafts and the first mounting shaft is located inside the circle formed by the steel wire rope. When the smoke exhaust window body is opened to the maximum angle, the steel wire rope is straightened.

[0011] Further technical solution: A placement groove for placing the steel wire rope is formed on one surface of the auxiliary support frame.

[0012] Further technical solution: A pressing plate is fixedly installed at one end of the auxiliary support frame close to the first mounting shaft. The pressing plate is used in cooperation with an auxiliary plate fixedly installed at the bottom of the second groove. The auxiliary plate is triangular. When the smoke exhaust window body is opened to the maximum angle, the pressing plate and the auxiliary plate cooperate to tightly press the steel wire rope.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When smoke exhaust is required, the telescopic member drives the rack to move downward. The rack drives the first mounting shaft to rotate through the meshing gear, and then the smoke exhaust window rotates outward to open. The smoke exhaust window is rotationally installed through the first mounting shaft and opened through the gear and the rack, so that the maximum angle that the smoke exhaust window can open is increased, improving the smoke exhaust effect. At the same time, the high transmission efficiency of the gear and the rack enables the smoke exhaust window to quickly open to the maximum angle, improving the opening speed of the smoke exhaust window. Moreover, the installation structure and the driving structure of the smoke exhaust window are both located on the lower side of the housing and shielded by a partition board, reducing the influence of smoke and heat during smoke exhaust on the equipment, reducing the probability of equipment damage, and ensuring the stable opening and closing of the smoke exhaust window.

[0014] 2. The guide plate and the smoke exhaust window are opened synchronously, and the mass distribution of the guide plate is the same as that of the smoke exhaust window, so that the rotational torque of the guide plate on the second installation shaft is the same as that of the smoke exhaust window on the first installation shaft, thereby achieving torque balance between the two after the smoke exhaust window is opened. Thus, the first installation shaft and the second installation shaft can be rotated with a minimal acting force, and the subsequent stability of the smoke exhaust window can be achieved, reducing the wear of the driving components and improving the service life of the equipment. After the smoke exhaust window is opened, the guide plate is in an inclined state. The smoke moving upward can move along the guide plate after contacting the guide plate, so that more smoke is discharged outward, further improving the smoke exhaust effect.

[0015] 3. When the smoke exhaust window is opened to the maximum angle, the steel wire rope is straightened. At the same time, the pressing plate will press the area of the steel wire rope tightly on the auxiliary plate. At this time, the steel wire rope is fixed in the first groove and both sides of the fixed position of the steel wire rope are in a straightened state. When the smoke exhaust window receives an external acting force that causes it to rotate, a corresponding acting force can be applied to the end of the auxiliary support frame through the steel wire rope, further ensuring the stability of the smoke exhaust window after it is opened.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0027] like Figures 1 - 8 As shown, a curtain wall smoke exhaust window provided by the present invention comprises a shell 1, the shell 1 is frame-shaped and a frame-shaped partition 2 is fixedly installed inside the shell 1, a smoke exhaust window body 3 is rotatably installed in the shell 1 through a first installation shaft 4, the first installation shaft 4 is located at one end of the smoke exhaust window body 3 and the smoke exhaust window body 3 is completely in contact with the partition 2 when it is rotated to a vertical state, a telescopic member 6 for driving the smoke exhaust window body 3 to rotate is arranged in the shell 1, the telescopic member 6 is fixedly installed in the shell 1 and the telescopic member 6 is eccentrically perpendicular to the first installation shaft 4, a rack 7 is fixedly installed at the output end of the telescopic member 6, the rack 7 is meshed with a gear 5 fixedly installed on the first installation shaft 4, and the gear 5 is coaxially arranged with the first installation shaft 4, an L-shaped baffle 8 is fixedly installed in the shell 1, and the telescopic member 6 is located inside the baffle 8 A guide plate 20 is rotatably installed in the shell 1 through a second installation shaft 21. The second installation shaft 21 is located at one end of the guide plate 20 and the guide plate 20 is in full contact with the partition 2 when the guide plate 20 is in a vertical state. The guide plate 20 and the smoke exhaust window body 3 are located on both sides of the partition 2 and the first installation shaft 4 and the second installation shaft 21 are located at both ends of the shell 1. The first installation shaft 4 is rotatably connected to the second installation shaft 21. First grooves 9 are provided on both sides of the shell 1. Both ends of the first installation shaft 4 and the second installation shaft 21 extend into the first groove 9. First synchronous wheels 10 are fixedly installed at both ends of the first installation shaft 4, and second synchronous wheels 22 are fixedly installed at both ends of the second installation shaft 21. The first synchronous wheels 10 and the second synchronous wheels 22 on the same side are rotatably connected with a synchronous belt 11.

[0028] In practical application of this embodiment, the housing 1 is fixedly installed at a set position on the curtain wall. When smoke exhaust is required, the telescopic member 6 drives the rack 7 to move downward. The rack 7 drives the first mounting shaft 4 to rotate through the meshing gear 5, so that the smoke exhaust window body 3 rotates outward to open. The smoke exhaust window body 3 is rotationally installed through the first mounting shaft 4 and opened through the gear 5 and the rack 7, which increases the maximum angle at which the smoke exhaust window body 3 can open, improves the smoke exhaust effect. At the same time, the high transmission efficiency of the gear 5 and the rack 7 enables the smoke exhaust window body 3 to quickly open to the maximum angle, improving the opening speed of the smoke exhaust window body 3. Moreover, the installation structure and the driving structure of the smoke exhaust window body 3 are both located on the lower side of the housing 1 and shielded by the partition plate 2, reducing the influence of smoke and heat during smoke exhaust on the equipment and reducing the probability of equipment damage, ensuring the stable opening and closing of the smoke exhaust window body 3. When the smoke exhaust window body 3 opens, the first mounting shaft 4 rotates. The first mounting shaft 4 drives the second mounting shaft 21 to rotate synchronously through the first synchronous pulley 10, the second synchronous pulley 22 and the synchronous belt 11, so that the guide plate 20 opens synchronously with the smoke exhaust window body 3. The mass distribution of the guide plate 20 is the same as that of the smoke exhaust window body 3, so that the rotational torque of the guide plate 20 on the second mounting shaft 21 is the same as the rotational torque of the smoke exhaust window body 3 on the first mounting shaft 4, thereby realizing the torque balance between the two after the smoke exhaust window body 3 opens. Thus, the first mounting shaft 4 and the second mounting shaft 21 can be rotated with a very small acting force and the subsequent stability of the smoke exhaust window body 3 can be realized, reducing the wear of the driving components and improving the service life of the equipment. After the smoke exhaust window body 3 opens, the guide plate 20 is in an inclined state. The smoke moving upward contacts the guide plate 20 and can move along the guide plate 20, so that more smoke is discharged outward, further improving the smoke exhaust effect. When not in use, the rack 7 moves in the reverse direction, and the smoke exhaust window body 3 and the guide plate 20 can be in sealed contact with the partition plate 2.

[0029] In an example of this embodiment, the telescopic member 6 is an electric telescopic rod. Of course, it can also be other components such as a hydraulic cylinder that can actively change the length. The electric telescopic rod drives the rack 7 to move up and down, thereby realizing the opening and closing of the smoke exhaust window body 3.

[0030] As Figures 1 - 8 shown, a curtain wall smoke exhaust window provided by the present invention is shown. Two groups of symmetrically distributed second grooves 12 are opened on the side of the housing 1 close to the smoke exhaust window body 3. The first mounting shaft 4 passes through the second grooves 12. An auxiliary support frame 14 is fixedly installed on the first mounting shaft 4. One end of the auxiliary support frame 14 away from the first mounting shaft 4 is fixedly connected to the side of the smoke exhaust window body 3. A connection port 13 for the auxiliary support frame 14 to enter is opened on the side wall of the second groove 12.

[0031] Specifically, a steel wire rope 16 is arranged on the auxiliary support frame 14. Both ends of the steel wire rope 16 are fixedly connected to the end of the auxiliary support frame 14 away from the first mounting shaft 4. Two groups of guide shafts 17 are fixedly installed in the second groove 12. The guide shafts 17 are located at both ends of the second groove 12. The steel wire rope 16 is wound around the two groups of guide shafts 17 and the first mounting shaft 4 is located within the circle formed by the steel wire rope 16. When the smoke exhaust window body 3 is opened to the maximum angle, the steel wire rope 16 is straightened.

[0032] Specifically, a placement groove 15 for placing the steel wire rope 16 is formed on one surface of the auxiliary support frame 14.

[0033] Specifically, a pressing plate 18 is fixedly installed at the end of the auxiliary support frame 14 close to the first mounting shaft 4. The pressing plate 18 is used in cooperation with an auxiliary plate 19 fixedly installed at the bottom of the second groove 12. The auxiliary plate 19 is triangular. When the smoke exhaust window body 3 is opened to the maximum angle, the pressing plate 18 cooperates with the auxiliary plate 19 to tightly press the steel wire rope 16.

[0034] In actual application of this embodiment, when the smoke exhaust window body 3 is opened, the auxiliary support frame 14 rotates synchronously with the smoke exhaust window body 3. The stability of the smoke exhaust window body 3 is improved through the auxiliary support frame 14. When the smoke exhaust window body 3 rotates when opened, the end of the auxiliary support frame 14 away from the first mounting shaft 4 moves away from the housing 1, which drives the steel wire rope 16 to move and stretch. When the smoke exhaust window body 3 is opened to the maximum angle, the steel wire rope 16 is straightened. At the same time, the pressing plate 18 presses the area of the steel wire rope 16 against the auxiliary plate 19. At this time, the steel wire rope 16 is fixed in the second groove 12 and both sides of the fixed position of the steel wire rope 16 are in a straightened state. When an external force that causes it to rotate acts on the smoke exhaust window body 3, a corresponding force can be applied to the end of the auxiliary support frame 14 through the steel wire rope 16, further ensuring the stability of the smoke exhaust window body 3 after it is opened.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0036] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
