Abstract: A fan gantry includes a frame structure, a supporting structure, a cover body and a thumb screw. The frame structure includes two side walls and a first connecting plate. The side walls define some spaces therebetween. Each side wall has an opening. The openings stagger with the spaces. The first connecting plate is disposed on one side wall. The supporting structure includes two structural plates opposite to each other and connected between the side walls. The structural plates define a channel aligning with the openings and allowing some electric cables to penetrate through. The cover body connects with the frame structure to cover the channel. The thumb screw is disposed on a second connecting plate of the cover body. When the cover body covers the channel, the second connecting plate abuts against the first connecting plate, and the thumb screw locks to the first connecting plate.
