In fire protection projects, smoke exhaust ducts are usually required. After the building is completed, the fire smoke exhaust ducts need to be installed in the building.

[0003] When traditional smoke exhaust ducts are installed and connected, they are usually fixed directly by multiple bolts. Although this can effectively ensure the firmness of the installation and use of the smoke exhaust duct, during the installation of the smoke exhaust duct, it is necessary to use external auxiliary tools to operate multiple bolts in sequence. The process is time-consuming and labor-intensive, which greatly reduces the installation efficiency of the smoke exhaust duct. Utility Model Content

[0008] As a further description of the above technical solution:

[0009] A threaded rod is rotatably connected inside the base, and the movable block is threadedly connected to the threaded rod.

[0010] As a further description of the above technical solution:

[0011] Both front and rear ends of the base are fixedly connected with hanging rings, the top of the hanging ring is fixedly connected with a hanging rod, the top of the hanging rod is provided with a top plate, and the top of the top plate is fixedly connected with a mounting plate.

[0012] As a further description of the above technical solution:

[0014] As a further description of the above technical solution:

[0015] One end of the threaded rod is fixedly connected with a protrusion, and the protrusion is a regular hexagon.

[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, the smoke exhaust pipe connection mechanism for building fire protection engineering is more convenient to install by rotating the first clamping plate on the upper end of the second clamping plate until the first clamping plate and the second clamping plate are closed, rotating the connecting rod, and the limit block passes over the first clamping plate and the second clamping plate until the limit block is stuck in the card slot to complete the installation.

[0018] 2. Compared with the prior art, this smoke exhaust pipe connection mechanism for building fire protection engineering uses a wrench to rotate the protrusion, thereby causing the threaded rod to rotate inside the base, so that the movable block moves inside the base, thereby adjusting the front and rear position of the pipe, and rotating the nut, so that the hanger moves along the top plate, causing the hanging ring to move up and down, thereby changing the height of the base, and the height of the pipe can be adjusted, which facilitates the docking of the first pipe and the second pipe.
