Abstract
The invention discloses an automatic unlocking door lock which comprises a lock case, a spring bolt, a spring, a lock cylinder, a linkage piece, a motor and a fire alarm sensor. The spring bolt is sleeved with the spring. A cavity for installation of the spring bolt and the spring is formed inside the lock case. An opening through which the spring bolt can stretch, retract, enter and exit is formed in the lock case. The lock cylinder is connected with the spring bolt through the linkage piece. The tail end of the spring bolt is connected with the motor through a rope. The motor rotates and drives the spring bolt through the rope to compress the spring. The motor is connected with the fire alarm sensor. The fire alarm sensor senses surrounding fire alarm signals. In this way, the automatic unlocking door lock can achieve the automatic unlocking function by sensing surrounding potential fire safety hazards, is applicable to large public places and particularly applicable to places with crowded people, and can ensure unobstructed evacuation.
