The utility model provides a shutter mechanism for a high voltage switchgear. The shutter mechanism comprises an upper shutter plate and a lower shutter plate. The two sides of the upper shutter plate and the lower shutter plate are respectively connected with an upper connecting plate and a lower connecting plate through connecting rods. The upper connecting plate and the lower connecting plate are connected respectively with an upper shaft sleeve and a lower shaft sleeve. The upper connecting plate and the lower connecting plate are further connected with fixing plates. The fixing plates are connected with bearing frames. The bearing frames are connected with inner side walls of the high voltage switchgear through the fixing plate. Between the upper connecting plate and the lower connecting plate is disposed a compression spring. The upper shaft sleeve and the lower shaft sleeve drive the upper connecting plate and the lower connecting plate to move so that the upper shutter plate and the lower shutter plate can be opened or closed along guide rods. The utility model has the advantages of simple structure and convenient and smooth use, without causing a jam phenomenon while pushing forward.
