Problems solved by technology

[0002] Duct fan is one of the commonly used tools for duct exhaust. It is used to circulate the air in the duct. For duct fans currently on the market, there are still a lot of problems. For example, duct fans cannot adapt to ducts of different sizes. It is necessary to customize the duct fan according to the size of the duct, so we propose a duct fan that can adapt to ducts of different sizes in order to solve the above problems

Abstract

The invention relates to a pipeline fan adaptive to pipelines of different dimensions. The pipeline fan primarily comprises an outer frame and a connecting shaft. A connecting hinge is fixed to the outer surface of the outer frame, the connecting hinge is connected to a fixed bar, a mounting plate is fixed to the tail end of the fixed bar, the connecting shaft is located in the middle of the innerside of the outer frame, a first fan blade and a second fan blade are connected through a fastening bolt, a first connecting rod is fixed to the inner side of the outer frame, a second connecting rodis connected below the first connecting rod, a fixed bearing is fixed to the tail end of the second connecting rod, and the connecting shaft penetrates the fixed bearing and is connected to the motor; as the first connecting rod and the second connecting rod are arranged, the first connecting rod can retract in the second connecting rod to adjust the distance between the outer frame fixed above the first connecting rod and the connecting shaft conveniently, so that the area of the outer frame of the fan is adjusted. The device is adaptive to pipelines of different dimensions conveniently.

Description

technical field [0001] The invention relates to the technical field of duct fans, in particular to a duct fan adaptable to ducts of different sizes. Background technique [0002] Duct fan is one of the commonly used tools for duct exhaust. It is used to circulate the air in the duct. For duct fans currently on the market, there are still a lot of problems. For example, duct fans cannot adapt to ducts of different sizes. It is necessary to customize the duct fan according to the size of the duct, so we propose a duct fan that can adapt to ducts of different sizes in order to solve the above-mentioned problems. Contents of the invention [0003] The object of the present invention is to provide a duct fan that can adapt to ducts of different sizes. [0004] The technical solution of the present invention is: a duct fan that can adapt to pipes of different sizes, mainly including an outer frame and a connecting shaft, the outer surface of the outer frame is fixed with a conn...
