Description

Technical Field

[0001] This application relates to the field of fire smoke exhaust duct technology, and in particular to a fire smoke exhaust duct. Background Technology

[0002] Fire exhaust ducts are an indispensable fire protection device in modern buildings. They are generally used in conjunction with smoke exhaust fans to stably exhaust the dense smoke generated during a fire, preventing smoke poisoning and suffocation of people inside the building.

[0003] For example, Chinese utility model patent CN217422519U discloses a fire-fighting smoke exhaust duct. This fire-fighting smoke exhaust duct can stably guide the splice of two sets of smoke exhaust duct bodies by the interlocking and nesting of the limiting grooves and positioning blocks on both sides of the smoke exhaust duct body. Furthermore, the joint installation of the inner plug rod of the positioning block and the positioning frame can stably support and seal the splice of the two sets of smoke exhaust duct bodies. Moreover, the connection between the limiting bolt on the outer side of the positioning block and the bottom of the hoisting connector can facilitate the stable hoisting of the smoke exhaust duct body by the staff, thus improving the convenience and stability of the smoke exhaust duct installation.

[0004] Regarding the aforementioned technologies, the inventors believe that fire exhaust ducts in these technologies are generally fixed and spliced ​​using bolts, which requires the use of external tools to disassemble and assemble the exhaust ducts. This makes the splicing of exhaust ducts cumbersome and reduces the efficiency of disassembly and assembly.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To address the issue that fire exhaust ducts in related technologies are typically fixed and spliced ​​using bolts, requiring external tools for disassembly and assembly, resulting in cumbersome operations and reduced efficiency, this application provides a fire exhaust duct.

[0007] The technical solution for a fire-fighting smoke exhaust duct provided in this application is as follows:

[0008] A fire-fighting smoke exhaust duct includes a smoke exhaust duct body, a snap-fit ​​plate fixedly installed at one end of the smoke exhaust duct body, and a snap-fit ​​seat fixedly installed at the other end of the smoke exhaust duct body. The snap-fit ​​seat has a snap-fit ​​groove that mates with the snap-fit ​​plate. The snap-fit ​​seat is provided with a limiting component that restricts the movement of the snap-fit ​​plate. The limiting component includes an insertion groove formed on the snap-fit ​​seat and communicating with the snap-fit ​​groove. A handle is slidably connected to the snap-fit ​​seat. The end of the handle extends into the insertion groove and is fixedly connected to a pressing plate. A spring is fixedly installed between the pressing plate and the side wall of the insertion groove.

[0009] Preferably, a snap-fit ​​post is fixedly installed on the side wall of the extrusion plate near the snap-fit ​​plate, and a snap-fit ​​hole that mates with the snap-fit ​​post is provided on the side wall of the snap-fit ​​plate.

[0010] Preferably, multiple snap-fit ​​posts and snap-fit ​​holes are provided at equal distances.

[0011] Preferably, a sealing gasket is fixedly installed on the side wall of the snap-fit ​​plate away from the snap-fit ​​seat.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. This application provides a snap-fit ​​groove on the snap-fit ​​seat, and provides a snap-fit ​​plate, as well as a handle, spring, insertion groove and pressing plate, so that the snap-fit ​​plate is inserted into the snap-fit ​​groove, and the spring presses the pressing plate to limit the snap-fit ​​plate, thereby limiting the snap-fit ​​plate and enabling the two exhaust pipe bodies to be quickly disassembled and assembled, thus improving the efficiency of disassembling and assembling the exhaust pipe bodies.

[0014] 2. This application improves the limiting effect of the snap-fit ​​plate by installing snap-fit ​​posts on the side wall of the extrusion plate and providing snap-fit ​​holes on the snap-fit ​​plate, thus preventing the snap-fit ​​plate from sliding inside the snap-fit ​​groove; at the same time, by installing sealing gaskets on the side wall of the snap-fit ​​plate, the sealing performance of the two exhaust pipe bodies when connected can be improved, reducing the leakage of flue gas.

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a fire-fighting smoke exhaust duct, referring to... Figure 1-4 The system includes a smoke exhaust duct body 1, with a snap-fit ​​plate 12 fixedly installed at one end of the smoke exhaust duct body 1 and a snap-fit ​​seat 11 fixedly installed at the other end of the smoke exhaust duct body 1. The snap-fit ​​seat 11 has a snap-fit ​​groove 111 that cooperates with the snap-fit ​​plate 12. The snap-fit ​​seat 11 is provided with a limiting component 13 that restricts the movement of the snap-fit ​​plate 12. The limiting component 13 includes an insertion groove 112 that is opened on the snap-fit ​​seat 11 and communicates with the snap-fit ​​groove 111. A handle 131 is slidably connected to the snap-fit ​​seat 11. The end of the handle 131 extends into the interior of the insertion groove 112 and is fixedly connected to a pressing plate 133. A spring 132 is fixedly installed between the pressing plate 133 and the side wall of the insertion groove 112.

[0022] Here, by pulling the handle 131, the handle 131 drives the pressing plate 133 to press the spring 132 and retract into the insertion groove 112. Then, the snap-fit ​​plate 12 installed on one exhaust pipe body 1 is inserted into the snap-fit ​​groove 111 opened on the snap-fit ​​seat 11 connected to the other exhaust pipe body 1. When the handle 131 is released, the spring 132 will push the pressing plate 133 to press the snap-fit ​​plate 12, so that the snap-fit ​​plate 12 is limited. The splicing of the two exhaust pipe bodies 1 can be completed quickly. Conversely, the two exhaust pipe bodies 1 can be separated and disassembled, which improves the convenience of disassembling and assembling the exhaust pipe bodies 1.

[0023] Reference Figure 2 A snap-fit ​​post 134 is fixedly installed on the side wall of the extrusion plate 133 near the snap-fit ​​plate 12, and a snap-fit ​​hole 121 that mates with the snap-fit ​​post 134 is provided on the side wall of the snap-fit ​​plate 12.

[0024] By inserting the snap-fit ​​pin 134 into the snap-fit ​​hole 121, the movement of the snap-fit ​​plate 12 can be better restricted.

[0025] Reference Figure 2 and Figure 3 Multiple snap-fit ​​posts 134 and snap-fit ​​holes 121 are provided at equal intervals.

[0026] By setting the snap-fit ​​pin 134 and the snap-fit ​​hole 121 at equal distances, it is easy for the snap-fit ​​pin 134 to extend into the snap-fit ​​hole 121.

[0027] Reference Figure 3 A sealing gasket 122 is fixedly installed on the side wall of the snap-fit ​​plate 12 away from the snap-fit ​​seat 11.

[0028] By incorporating a sealing gasket 122, the sealing performance of the exhaust pipe body 1 during splicing can be improved, preventing smoke leakage.

[0029] The implementation principle of a fire exhaust duct in this application embodiment is as follows: In use, firstly, by pulling the handle 131, the handle 131 drives the squeezing plate 133 to squeeze the spring 132 and retract it into the insertion groove 112. Then, the snap-fit ​​plate 12 installed on one exhaust duct body 1 is inserted into the snap-fit ​​groove 111 opened on the snap-fit ​​seat 11 connected to the other exhaust duct body 1. When the handle 131 is released, the spring 132 will push the squeezing plate 133 to squeeze the snap-fit ​​plate 12, so that the snap-fit ​​post 134 cooperates with the snap-fit ​​hole 121, thereby limiting the snap-fit ​​plate 12 and quickly completing the splicing of the two exhaust duct bodies 1. Conversely, the two exhaust duct bodies 1 can be separated and disassembled, which improves the convenience of disassembling and assembling the exhaust duct body 1.
