Abstract

The invention relates to a fireproof lock for a ship. The fireproof lock for the ship comprises a lock cylinder, a spring bolt, a cam mechanism and a buckle. The cam mechanism comprises a rotating shaft, a stop block and a torsion spring. The lock cylinder is located on the outer side, one end of the lock cylinder is provided with a key insertion hole, and the other end of the lock cylinder is connected with the cam mechanism. The spring bolt is located on the inner side and is a spring bolt with the middle concaved into an opening cavity. The cam mechanism is arranged in the cavity of the spring bolt. The spring bolt is connected with the lock cylinder through the cam mechanism. The rotating shaft is connected with the center position of the lock cylinder. The stop block is arranged at the end of the outer portion of the rotating shaft, and a movable structure is composed of the stop block and the rotating shaft. The movable structure is connected with the torsion spring to form a force-controllable movable structure. The fireproof lock for the ship has the beneficial effects that firstly, the fireproof lock is made of an all-metal material and does not deform after being heated; secondly, the embedded type buckle is adopted, the structure is simple, and the appearance is elegant; thirdly, the lock cylinder is connected with the spring bolt through the cam mechanism, and therefore the requirement of the door lock is met under the premise that the fireproof requirement is met; and fourthly, the self-ejecting type spring bolt is adopted, and use is convenient.
