AI Technical Summary
Existing door closers cannot meet the need to keep doors open for extended periods and automatically lock at specific angles, and they cannot automatically unlock in the event of a fire.
A locking device comprising a first rod and a second rod that are rotatably connected to each other is designed. The door can be automatically locked and unlocked through a linkage rod, a locking structure and a traction power source. The door can be automatically unlocked in case of fire by using an electromagnet and a high-temperature self-unlocking mechanism.
It enables the door to automatically lock and remain fixed at a specific angle, and automatically unlock in the event of a fire, ensuring that the door can close automatically and prevent the fire from spreading.
