The invention provides a pirate-defending door lock of an exposed deck weather tight steel door of a vessel. The pirate-defending door lock comprises a lock seat, a lock sleeve, a lock column, a key and a key handle. The two ends of the lock column are screwed in the lock sleeve and the lock seat to lock the exposed deck weather tight steel door internally or externally. The door lock has outstanding beneficial effects, and the defect that a ring latch of an unattended cabin of an exposed deck can be opened through hamming is overcome. The embedded type lock column with a triangular column is adopted, and the possibility that the lock is opened through a universal tool in a clamping or stirring manner or other manners is eliminated. A trapezoidal thread connecting manner is adopted, and thus the time spent for opening the lock through a simple tool is greatly prolonged. The door lock is simple and light in structure, resistant to smashing and prying, resistant to commonly-used tools and extremely high in safety and is a reliable door lock device for defending pirates for the vessel.
