[0002] Smoke and exhaust ducts are a general term for air ducts that pass through buildings according to design specifications, or are located in fire-hazardous areas of mechanical pressurized air supply and smoke prevention systems, and air ducts that cross fire-resistant partitions and mechanical smoke exhaust systems.

[0003] However, it still has the following disadvantages in actual use:

[0004] When workers install existing smoke exhaust ventilation ducts, they usually install the smoke exhaust ventilation ducts in an integrated manner. This installation method requires multiple workers to cooperate with each other to achieve the purpose of installation due to the large volume of the integrated smoke exhaust ventilation duct. It is not only time-consuming and labor-intensive, but also has low installation efficiency. Utility Model Content

[0008] Furthermore, the taking mechanism includes a mounting frame arranged above the smoke exhaust pipe, a spring block is slidably connected above the mounting frame, a handle is fixedly connected above the filter, limit position components are arranged at both ends of the handle, and a slot is opened above the smoke exhaust pipe.

[0009] Furthermore, the limiting assembly includes sliders arranged at both ends of the handle, and a limiting hole is provided on the inner side of the mounting frame, and the sliders are adapted to the limiting hole.

[0010] Furthermore, the handle passes through the interior of the slot, the slot and the interior of the smoke exhaust pipe pass through each other, and a sealing gasket is provided at the joint between the handle and the slot.

[0011] Furthermore, the driving assembly includes a rotating shaft arranged at one end of the elastic rod, and a connecting block is fixedly connected to the outer surface of the rotating shaft.

[0012] Furthermore, the movable rod and the connecting block are arranged on the same horizontal plane.

[0013] Furthermore, a thread groove is provided inside the slider, and the bolt and the slider are threadedly connected.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] The utility model is provided with an installation mechanism, which slides the sliders installed on both sides of the multiple smoke exhaust pipes into the interior of the frame for sliding connection. After sliding to the installation position, the slider can squeeze one end of the movable rod to make the movable rod slide in the movable groove, so that the movable groove squeezes the connecting block installed at one end of the rotating shaft, so that the elastic rod fixedly connected to the rotating shaft is flipped, so that one end of the two groups of elastic rods fits and supports the outer surface of the slider, and at the same time, by rotating the bolts threaded in the screw groove, the bolts extend through the screw groove to the interior of the fixed block and are threadedly connected to the slider, which can facilitate users to install the ventilation duct, improve the installation efficiency, and increase the stability of the installation.

[0016] Based on the above beneficial effects, a taking mechanism is provided. After the ventilation duct is used as above, the spring block arranged above the mounting frame can be pressed to make the spring block slide down inside the mounting frame, and at the same time, the spring block squeezes the slider engaged in the clamping hole, thereby releasing the installation connection formed by the handle with sliders installed on both sides and the mounting frame, making it convenient for the staff to pull the handle upwards so that the filter connected to the handle can be taken out through the slot, which can facilitate the user to pull out the filter for cleaning, and is convenient.
