Description

Novel radian buffer structure of industrial fan

Technical Field

The utility model relates to the technical field of industrial fans, in particular to a novel radian buffering structure of an industrial fan.

Background

In a factory, the space of the factory is usually large, the possibility of installing an air conditioner is extremely low, but in hot summer, the temperature of the factory is high, and on the premise that the air conditioner cannot be installed, only an industrial fan can be installed selectively, and although the types of the industrial fans are many, the requirements of users cannot be met.

Current industrial fan adopts the rigid connection of fastener when the installation, and the noise that leads to the during operation fastener to produce is big, and secondly current industrial fan, the noise that produces when the flabellum rotates is great, therefore the urgent need a novel industrial fan radian buffer structure solves above-mentioned weak point.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a novel radian buffering structure of an industrial fan, which solves the problems that when the conventional industrial fan is installed, the fastening piece is in hard connection, so that the noise generated by the fastening piece is high during the work, and secondly, the noise generated by the conventional industrial fan is high during the rotation of fan blades.

The utility model provides the following technical scheme: the utility model provides a novel industry fan radian buffer structure, includes fan main shaft subassembly and four flabellums, four directions all are connected with the connecting block about fan main shaft subassembly about from top to bottom, four all seted up two first connecting holes and symmetry setting on the connecting block, four all seted up second connecting hole and symmetry setting on the flabellum, four the connecting block all is connected with the flabellum through fastening bolt first connecting hole and second connecting hole in proper order and cooperation nut.

Preferably, all be provided with soft rubber cushion collar in first connecting hole and the second connecting hole, be provided with the internal thread on the inside wall of soft rubber cushion collar.

Preferably, the surface of the fan blade is provided with a plurality of micropores which are uniformly distributed.

Preferably, the cross section of the soft rubber buffer sleeve is circular.

Preferably, the diameters of the first connection hole and the second connection hole are equal.

Compared with the prior art, the utility model has the following beneficial effects:

the fan blade is simple in structure and reasonable in design, the connecting block, the first connecting hole, the second connecting hole and the soft rubber buffer sleeve are arranged, and the mutual matching effect of the connecting block, the first connecting hole, the second connecting hole and the soft rubber buffer sleeve is utilized, so that the hard connection of a fastener can be effectively blocked, the noise is effectively reduced, and the noise generated when the fan blade works can be absorbed and reduced by arranging the plurality of uniformly distributed micropores.
