Fire-fighting anti-theft lock

Abstract

The invention belongs to the field of fire safety, and particularly relates to a fire-fighting anti-theft lock which comprises two lock shells, a heat insulation plate is fixedly arranged between the two lock shells, an inner cavity is formed in the heat insulation plate, a lock body is symmetrically arranged in each lock shell relative to the heat insulation plate, and each lock body is provided with a pressing cavity with an opening deviating from the heat insulation plate. A lock cylinder is arranged in each pressing cavity in a rotating and sliding mode, each lock cylinder is connected to the inner wall of the corresponding pressing cavity through a reset spring, an emergency unlocking mechanism capable of normally unlocking is arranged in the two lock shells and the heat insulation plate, and a temperature control unlocking mechanism used for emergency automatic unlocking is arranged in the heat insulation plate. The two lock shells are internally provided with temperature control mechanisms used for sensing the temperature and making a response to control the temperature control unlocking mechanism, when a fire happens outside a warehouse and an air bag in the lock shell outside the locked warehouse roller shutter door is subjected to high temperature, the air bag drives an insertion rod to slide, the insertion rod slides into an insertion hole of the roller shutter door, the roller shutter door is better locked, and the safety of the warehouse is improved. The fire is prevented from spreading into the storey warehouse.
