The invention discloses a rapid sealing assembly 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 and an inner side connecting ring. When the rear end cover movably sleeves the front end ring plate, a pressing driving ring drives an axial abutting rod to axially move and drives a radial pressing rod to radially move, so that two driving modes are synchronously realized, and the purpose that the front sealing ring and the rear sealing ring abut against the outer side of the periphery of the tail shaft is synchronously realized.

    本发明公开了一种快捷密封装配式艉轴密封装置,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;本发明在后端盖移动套接于前端环板上时,通过抵压驱动环带动轴向抵接杆进行轴向移动以及带动径向抵压杆进行径向移动,如此同步实现两种驱动模式,同步实现了前密封环和后密封环抵压于艉轴四周外侧的目的。
