[0023] The left outer wall of the barb 14 is arc-shaped, allowing for smooth contact and engagement.

[0024] In use, the hall door sill device is fixed in the elevator shaft by connecting brackets, expansion bolts, etc. When someone in the elevator car presses the button for the corresponding floor, the elevator car will reach the corresponding floor. After the car stops, the door knife arm of the elevator will open, and the opened door knife arm will clamp the two door balls on the door lock assembly 5. The moving door ball on the door lock assembly 5 will drive the lock hook to rotate and lift downwards. The plug assembly on the lock hook will disconnect from the switch assembly 6 mounted on the door head base plate assembly 1. The motor on the elevator door operator rotates and drives the door knife to move through the belt, thereby driving the active hanging plate assembly 4 to slide on the guide rail 2. The linkage steel wire rope assembly 7 fixed on the active hanging plate assembly 4 moves along with it. Finally, the driven hanging plate assembly 3 moves to the same end with the active hanging plate assembly 4. When it moves to the limit position of the rightmost door head base plate assembly 1 and stops, the elevator door is fully opened, and the counterweight spring is also firmly pulled open, allowing people inside and outside the elevator car to enter and exit freely. When a person inside the elevator presses the close button or no one outside presses the call button within a certain time, the motor drives the elevator door knife to close. The force acting on the door ball of the door lock assembly 5 disappears, and the lock hook on the door lock assembly 5 returns to a horizontal position under its own weight. At the same time, the counterweight spring 9, which is fixed to the hook of the driven plate assembly 3 and the hook assembly 10 respectively, automatically tightens, thereby driving the driven plate assembly 3 to move to the left. The driving plate assembly 4 moves along with it under the action of the linkage wire rope assembly 7. When the contact assembly on the door lock assembly 5 is inserted into the switch assembly, the limiting device on the base plate assembly stops. The driven plate assembly 3 and the driving plate assembly 4 stop moving. At the same time, the plug assembly on the door lock assembly 5 is also fully in contact with the auxiliary contact assembly, and the circuit is fully connected. After receiving the command, the elevator car moves up and down. When the elevator malfunctions and the doors cannot be opened normally, or when maintenance is required, the emergency unlocking component 7 can be turned using a triangular key. The unlocking rod on the emergency unlocking component 7, also known as the lock plate 22, moves the limit rod through the locking hole, pushing the bolt of the door lock component 5 so that the lock hook is lifted downwards. The outer wall of the lock hook is arc-shaped, so it can be smoothly locked into the locking slot. When the lock hook is lifted downwards, the elevator doors on both sides can be opened by gently pulling them with your hands from the outside of the car.
