Detailed Description

With combined reference to fig. 2 to 4, according to an embodiment of the present invention, a fixing device for a centrifugal fan includes a mounting member and a fixing member, wherein the mounting member is used for fixing an air outlet flange 2 of the centrifugal fan; the shell of the centrifugal fan is fixedly connected with the mounting piece through the fixing piece.

Centrifugal fan fixes on the installed part through air-out flange 2, and the shell that combines centrifugal fan again carries out fixed connection through mounting and installed part for whole centrifugal fan carries out fixed connection in two at least places and installed part, has avoided centrifugal fan shell and inside motor to be in the cantilever beam state, has improved the fixed fastness of centrifugal fan shell and inside motor on the installed part, has improved centrifugal fan's the atress condition greatly, has effectively improved centrifugal fan's shock resistance.

The fixing piece and the mounting piece form an annular support, and the centrifugal fan is arranged in the annular support.

Through the ring carrier that mounting and installed part constitute, encircle whole centrifugal fan, the convenience is fixed to the shell is diversified, ensures centrifugal fan's stability.

The fixing piece comprises a plurality of fixing plates which are sequentially connected to form a bending structure, and the annular support is formed by connecting two ends of the bending structure with the mounting piece; the two sides of the bending structure are connected with the shell.

the fixing plate can be a straight plate structure, and a plurality of straight plates are connected at the bent positions to form a bent structure; or the fixed plate is of a bent plate structure and is formed by connecting a plurality of bent plates; or the fixed plate comprises a straight plate and a bent plate which are connected in sequence; a plurality of fixing plate structures are adopted, so that the centrifugal fan is convenient to process and assemble, and the outer periphery of the centrifugal fan is effectively coated.
