Description

Technical Field

[0001] The utility model relates to the technical field of air ducts, and more specifically, to a smoke prevention and exhaust composite air duct. Background Technique

[0002] An air duct is a pipeline system used for air transportation and distribution. There are two types: composite air ducts and inorganic air ducts. Composite air ducts are represented by Durkduct air ducts. They can be classified according to cross-sectional shape and material. The production of stainless steel air ducts involves applying a sealant (such as neutral silicone sealant) at the seams such as the bite seams, rivet seams, and the four corners of the flange flanges. The surface dust and oil should be removed before applying the sealant.

[0003] After retrieval, a composite smoke prevention and exhaust air duct with the existing publication number CN213178683U includes a smoke exhaust air duct body. One end of the smoke exhaust air duct body is provided with a tail of the smoke exhaust air duct, and the other end of the smoke exhaust air duct body is provided with a head of the smoke exhaust air duct. The cross-sectional area of the tail of the smoke exhaust air duct is the same as that of the smoke exhaust air duct body, and the cross-sectional area of the head of the smoke exhaust air duct is smaller than that of the smoke exhaust air duct body. At the same time, the head of the smoke exhaust air duct can be sleeved inside the tail of the smoke exhaust air duct. It can ensure the fixed connection between two adjacent composite smoke prevention and exhaust air ducts. Also, in case of a fire, it can not only absorb the heat in the smoke, reduce the damage of high-temperature smoke to the pipe body, but also reduce the contact between the fire and oxygen to help with fire extinguishing.

[0004] When installing and processing adjacent composite air ducts, due to poor sealing at the connection position of the air ducts, the phenomenon of smoke leakage easily occurs, and the use effect is not good. Therefore, we propose a smoke prevention and exhaust composite air duct to solve the above existing problems. Content of the Utility Model

[0005] 1. Technical Problems to be Solved

[0006] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a smoke prevention and exhaust composite air duct. Duct A and duct B are connected and fixed to the pipe joint A and pipe joint B through a locking member. Then, the pressing plate is held by the traction frame, and the sealing structure composed of the pressing plate and the side plate is pressed at the connection of the pipe joint A and pipe joint B. The rubber pad and the rubber seat are used for sealing the connection of the pipe joint A and pipe joint B, which has good smoke prevention and exhaust protection performance and improves the use effect. The end of the side plate is welded with an assembly plate, and a permanent magnet is fixedly connected inside the step groove of the assembly plate. When sealing the connection of the pipe joint A and pipe joint B, the assembly plate of the side plate is magnetically fixed through the permanent magnet, which has an auxiliary positioning effect. Under the magnetic attraction of the permanent magnet, the two assembly plates are attached together, and the assembly holes on the surface of the assembly plate correspond to each other, facilitating the insertion and fixation of the locking member, and the assembly process is time-saving and labor-saving.
