Description

technical field [0001] The invention relates to the technical field of locks, in particular to a marine door lock and a using method thereof. Background technique [0002] Since the ship needs to work on the water for a long time, as the weather changes, strong turbulence often occurs when the ship sails under the influence of wind and waves. At present, the lock grooves of cabin door locks are mostly wedge-shaped, and the door is locked by the principle of wedge blocks (the lock head slides through the hypotenuse of the wedge-shaped lock groove). This kind of marine door lock has the following disadvantages: [0003] 1. The lock head is easy to slide back, causing the door lock to open automatically, and it is easier to slide back due to the bumps caused by the action of waves on the sea; [0004] 2. The position of the lock head cannot be guaranteed when locking the door. For example, the staff is weak and the lock head only rotates 45 degrees. It seems that the door has ...
