The utility model relates to a centrifugal oil filter assembly device for a large diesel engine, in particular to a centrifugal oil filter with a locking mechanism. The utility model mainly solves the problem that the centrifugal oil filter is in actual operation, because the centrifugal oil filter is locked by the thread in the actual operation, and possibly because of the failure at the speed rotation and accompanied by the strong vibration. The technical scheme of the utility model is used to solve the technical problem is: centrifugal oil filter with a locking mechanism, which comprises a shell and a rotor core is installed in the casing, the rotor shaft through the rotor core by the shell top nut thread screwed and fixed, which is at the bottom of the shell with a flange, the flange along the circumference of the outer side of the bottom set a number of edges with snap buckle, provided with a plurality of clamping slot matching on the base butt circumferential surface, groove bottom wall of the base card set a week through the locking groove, buckle slot along the locking groove of the rotating shell and the base lock. In order to improve the sealing performance, a rubber sealing ring is arranged on the butt joint of the shell and the base, and the clamping force is used for locking the clamping groove. By the utility model, the reliability of the oil filter assembly can be greatly increased.
