The invention belongs to the technical field of underwater vehicles, and particularly relates to a cabin door locking device of an underwater vehicle. The locking device comprises a left cabin door locking seat and a right cabin door locking seat which are respectively arranged on a left cabin door and a right cabin door; the sealing driving device is connected with the locking bolt through the pushing nut; under the driving of the sealing driving device, the locking bolt can move back and forth; bolt holes are respectively formed in the left cabin door locking seat and the right cabin door locking seat; when the cabin door is completely closed, the bolt holes in the left cabin door locking seat and the right cabin door locking seat are kept coaxial with the guide hole of the bolt guide seat, and the sealing driving device pushes the locking bolt forwards by pushing the nut, so that the front part of the locking bolt penetrates through the guide holes of the left cabin door locking seat, the right cabin door locking seat and the bolt guide seat at the same time, and locking is realized. According to the invention, the problems of insufficient locking degree after the cabin door of the underwater vehicle is closed and vibration after the cabin door is closed can be solved.
本发明属于水下潜航器技术领域,具体涉及一种水下航行器的舱门锁紧装置。一种适应于水下潜航器舱门的锁紧装置,包括:分别安装于左、右舱门的左舱门锁紧座、右舱门锁紧座;密封驱动装置通过推动螺母连接锁紧插销;在密封驱动装置的驱动下,锁紧插销能够前后移动;左舱门锁紧座、右舱门锁紧座上分别设有插销孔;当舱门完全关闭时,左舱门锁紧座、右舱门锁紧座上的插销孔与插销导向座的导向孔保持同轴,密封驱动装置通过推动螺母将锁紧插销向前推出,使锁紧插销前部同时穿过左舱门锁紧座、右舱门锁紧座和插销导向座的导向孔,实现锁紧。本发明可以解决水下潜航器舱门关闭后锁紧程度不足以及舱门关闭后的震动问题。
