Door lock of roller shutter door and working principle of door lock
The invention discloses a door lock of a roller shutter door and a working principle of the door lock and relates to the technical field of roller shutter doors. The door lock of the roller shutter door comprises a lock cylinder, a spring, a pull cord, a separation and reunion device and a motor, wherein the spring drives the lock cylinder to move toward the roller shutter door and locks the roller shutter door, one end of the pull cord is connected with the lock cylinder, and the other end of the pull cord is connected with the separation and reunion device; the motor drives the separation and reunion device to roll up the pull cord, so that the lock cylinder is separated from the roller shutter door and unlocks the roller shutter door; after the motor stops, the spring stretches the pull cord which is rolled by the separation and reunion device, and the lock cylinder is driven to move toward the roller shutter door and lock the roller shutter door. The door lock has the advantages that no additional operation is needed for unlocking or locking the roller shutter door, the roller shutter door only needs to be ascended or descended normally, the roller shutter door unlocking or locking operation can be completed automatically through the door lock of the roller shutter door, operation is simple, and the antitheft effect is good.
