The unlocking manner of the emergency escape lock is to kick the lock open with a feet, the emergency escape lock can be conveniently unlocked in a fire hazard, the crew can be prevented from being scalded, the escape speed is increased and the safety of the crew is ensured; in addition, the tail end of the inserted pin of the emergency escape lock is provided with a rubber gasket, vibrations can be effectively reduced when the inserted pin is placed in an inserted pin hole, and the service life of the emergency escape lock is prolonged.

Description

technical field [0001] The invention relates to a lockset, in particular to an emergency escape lock, which is mainly used on a cabin door in a ship cabin. Background technique [0002] Some accidents cannot be avoided during the voyage of the ship, and fire is a common disaster on board. Since there is only one hatch in the cabin, once a fire breaks out, people in the cabin are very likely to panic and cannot open the escape lock on the hatch in time. Therefore, the escape lock of the hatch has strict design requirements and must be able to effectively ensure the safety of the cabin. The crew inside were able to quickly open and escape. [0003] However, in the past, the escape lock on the cabin door was mostly opened by a bolt or a wrench. For example, the patent No. is the Chinese patent of 02260909.1, which discloses a split type anti-theft and fire escape lock. Although the escape lock disclosed in this patent uses a wrench to open the escape lock, the opening speed ...

Problems solved by technology

In the past, the escape lock mostly used the bolt or the deadbolt to be directly fixed to the door frame. When the escape lock vibrated continuously, it would continuously impact the bolt or the deadbolt, resulting in damage to the bolt and the deadbolt, thereby reducing the service life of the escape lock. It is also extremely inconvenient to replace the escape lock on board
