[0002] In the modern building safety system, the fireproof lock as the key accessory of the fireproof door plays an important role in protecting the life and property safety, and the fireproof door and the fireproof lock jointly constitute an important defense line to prevent the spread of fire and gain valuable time for personnel evacuation. When the fire occurs, the fireproof lock not only needs to ensure the tight closure of the fireproof door to prevent the penetration of fire and smoke, but also needs to maintain the stability of its structure so as to be normally opened and closed in the emergency. The existing fireproof lock has many deficiencies in the aspect of deformation resistance. The hardness and toughness of some ordinary metal lock bodies are greatly reduced in the several hundred degrees Celsius high temperature commonly seen in the fire scene, and the lock bodies are easily deformed due to thermal stress and external force, resulting in the lock core being stuck and the bolt being unable to normally retract, so that the fireproof door loses the protection and evacuation functions. In addition, heavy objects may fall and hit the lock body during the fire, causing the lock body to be unable to uniformly disperse stress and resulting in local deformation and affecting the normal operation of the entire fireproof lock.

[0003] The existing fireproof lock cannot resist high temperature, is easily deformed due to thermal stress, cannot prevent the impact of falling heavy objects, causes the surface to be deformed, the visibility is low due to smoke or power failure in the fire scene, the lock body cannot be found in time, and the escape time is delayed.
