The invention discloses a sliding type locking-sealing device. The sliding type locking-sealing device comprises a fixed housing, wherein a locking slide block is slidably arranged in the fixed housing, and an unlocking cavity and a locking cavity which are not communicated and connected mutually are formed between the locking slide block and the fixed housing. A locking seal is further arranged on the locking slide block and corresponds to the position of a sealing seat on a stern shaft. An unlocking cavity lining is fixedly installed in the fixed housing, an unlocking cavity seal is arranged between the unlocking cavity lining and the locking slide block, a slide block retainer ring is fixedly installed on the locking slide block, a retainer ring seal is arranged between the slide block retainer ring and the unlocking cavity lining and is located on the rear side of the unlocking cavity, and the unlocking cavity seal is located on the front side of the unlocking cavity. A locking cavity lining is fixedly installed in the fixed housing, and a locking cavity seal is arranged between the locking cavity lining and the locking slide block and is located on the front side of the locking cavity. By means of the sliding type locking-sealing device, maintenance and replacement of a ship stern shaft sealing device can be conveniently achieved.
