[0020] The following combination Figure 1-Figure 5 The utility model is described in further detail.

[0021] The embodiment of the present utility model discloses a transport anti-rotation device for a ventilator, which is used when the ventilator is in a non-working state, such as a transport state. The ventilator 4 includes a main shaft 5 and a base 8. The main shaft 5 is arranged above the base 8 and provides power for the impeller to rotate.

[0022] Reference Figure 1 、 Figure 2 、 Figure 3A transport anti-rotation device for a ventilator includes a fixing base 1 and a clamp 2. The fixing base 1 has an L-shaped structure and the bent end 7 of the fixing base 1 is fixedly arranged on the base 8 of the ventilator 4. The main body 3 of the fixing base 1 is vertically arranged and extends to one side of the main shaft 5 of the ventilator 4. The clamp 2 is arranged on one side of the main body 3 of the fixing base 1. The clamp 2 is arranged around the outer surface of the main shaft 5 and fixes the main shaft 5, which can effectively prevent the ventilator 4 from rotating when it is not working.

[0023] Reference Figure 2 The radius of the hoop 2 is determined according to the diameter of the main shaft 5 to be fixed as needed. A buffer yarn 9 is wrapped around the hoop 2 or a buffer pad is laid between the main shaft 5 to play a buffering role and prevent the main shaft 5 from wearing.

[0024] Reference Figure 2 、 Figure 4 A fixing hole 10 is opened at the end of the hoop 2, and the end of the hoop 2 is connected and fixed to one side of the main part 3 of the fixing seat 1 through a connecting bolt 11.
