Filter shell

Abstract

The utility model discloses a filter housing, which comprises a housing body, a fixing mechanism and a dustproof mechanism, the housing body comprises an upper housing and a lower housing, the upper housing and the lower housing are hinged, the fixing mechanism is arranged between the upper housing and the lower housing, the fixing mechanism is used for fixing the upper housing and the lower housing, and the dustproof mechanism is arranged between the upper housing and the lower housing. The dustproof mechanisms are arranged on the two sides of the upper shell and used for preventing dust from entering the device through holes in the surface of the upper shell, a plurality of fixing columns are fixedly connected to the bottom of the inner side of the upper shell, and threaded grooves are formed in the tops of the fixing columns. Through the arrangement of the fixing mechanism, after the upper shell and the lower shell are fixed through the clamping bolt, the clamping rod in the fixing mechanism can be inserted into the clamping groove, so that the clamping bolt can be limited, the clamping bolt cannot rotate, the clamping bolt can be completely prevented from loosening, and the service life of the clamping bolt is prolonged. Therefore, the reliability of fixing the filter by the device can be improved.
