Description

Technical Field

[0001] The utility model relates to the technical field of axial flow fans, in particular to a mounting assembly and an axial flow fan. Background Art

[0002] When an axial fan is operating, its blades push air in the same direction as the axis, hence the name. Generally speaking, large axial fans are primarily used for exhaust in places like dust and gravel pits; medium-sized axial fans are primarily used for indoor ventilation and heat removal, such as in granaries; and small axial fans are primarily used for ventilation and heat dissipation in mechanical equipment, such as electrical cabinets.

[0003] Generally, small and medium-sized axial fans are installed directly on the wall or the inner wall of the equipment by setting a connecting plate on the edge and bolting the connecting plate together. They are used for dust removal, heat dissipation and other tasks, or a connecting plate is attached to the outside of the axial fan casing. Usually, only a simple connecting plate is used, which does not have additional functions and can only serve as an auxiliary connection.

[0004] During actual use, the motor inside the axial flow fan drives the fan to rotate, which will generate vibration and then generate noise. Generally, the axial flow fan itself does not have a shock-absorbing effect, and direct connection or installation connection through a simple connecting plate will not produce a shock-absorbing effect. Therefore, in order to reduce the vibration of the axial flow fan and reduce the noise generated during the operation of the axial flow fan, a mounting assembly that can reduce vibration and noise is needed. To this end, the present invention proposes a mounting assembly and an axial flow fan for solving the above problems. Utility Model Content
