The invention discloses a locking type tail shaft sealing device. The device comprises a tail shaft, a front end ring plate, a rear end cover, a front sealing ring, a rear sealing ring, a sealing connecting mechanism, an inner side connecting ring and a locking mechanism. According to the invention, the locking mechanism is additionally arranged, locking threaded cylinders are rotationally connected to locking threaded columns in a threaded mode, meanwhile, abutting folded edges are rotationally connected to the outer side face of the front end ring plate in an abutting mode, in this way, axial locking of the multiple locking threaded columns is formed, then the axial connection stability of the rear end cover is guaranteed, and the structure is more stable.

    本发明公开了一种锁定式艉轴密封装置,包括艉轴、前端环板、后端盖、前密封环、后密封环、密封连接机构、内侧连接环、锁定机构;本发明增设了锁定机构,通过锁定螺纹筒螺纹旋转连接于锁定螺纹柱上,同时将抵压折边旋转抵压连接于前端环板的外侧面上,如此形成了多个锁定螺纹柱的轴向锁定,进而保证了后端盖的轴向连接稳定性,结构更加稳固。
