Further, the protection component comprises a second spring 24 and a guide rod 26, an opening for the guide rod 26 to extend into is formed in the surface of the base plate 1, a washer 8 is arranged in the opening, a penetrating opening for the guide rod 26 to penetrate through and be in sliding connection with the washer 8 is formed in the surface of the washer 8, the end portion of the guide rod 26 is clamped with the surface of the first drive plate 4, two ends of the second spring 24 are fixedly connected with the surface of the washer 8 and the surface of the guide rod 26 respectively, when the elevator car door is used, if a control system of an elevator system or a door machine fails, a power supply is cut off to stop a door opening motor, the two door knives 3 can still be closed under the reset action of the second spring, when a landing door ball is located between the two door knives 3, the lock hook 17 can be unlocked, a person can rescue the elevator car door by opening, and if the landing door ball does not fall between the two door knives 3, therefore, the lock hook 17 on the synchronous door vane device cannot be unlocked with the lock piece 25, so that the car door cannot be opened through external force, the situation that the car door is opened in a non-landing stop area to harm personal safety accidents is avoided, and the safety of the device in use is improved.

Further, the minimum distance between the two gate knives 3 is smaller than the diameter of the layer gate ball, and as the minimum distance between the gate knives 3 is smaller than the diameter of the layer gate ball, the gate knives 3 can be propped open by the layer gate ball, so that the first connecting plate 2 and the second driving plate 13 are driven to rotate.

The working principle is as follows: when the integrated car door lock synchronous knife is used, when a car needs to run in a hoistway, a door opening motor applies acting force on a door knife shaft 23, as shown in figure 1, at the moment, two door knives 3 are in a closed state, a first driving plate 4 is blocked by a baffle 7, so that the whole device moves towards a door closing direction, in the moving process, the two door knives 3 always clamp a landing door ball, so that the car door and the landing door move synchronously, until only a gap of about 10 mm is left between a pair of car doors, an unlocking plate 6 on a bottom plate of a door machine triggers the baffle 7 on the bottom plate 1 to act, the baffle 7 is driven to be separated from the first driving plate 4, the first driving plate 4 rotates towards the direction of a lock hook 17 by taking a first shaft pin 14 as a center due to the continuous acting force of the door opening motor, so that the first shaft pin 14 rotates, the first connecting plate 2 rotates, and the two door knives 3 are driven to start to open, the first shaft pin 14 rotates to drive the second driving plate 13 to rotate, the second driving plate 13 rotates to drive the roller 15 to roll along the arc-shaped part 18, the lock hook 17 keeps a static state until the two door knives 3 are completely opened, the synchronous door knife device continues to move in the door closing direction until the car door and the landing door are completely closed, the door opening motor keeps acting force, the car door lock and the synchronous door knives are integrally arranged on the car door, the installation and debugging are convenient, the car door and the landing door are mutually kept synchronous in the respective whole opening process, and the synchronism of the car door and the landing door is relatively high;

when the car stops at a landing, the car door and the landing door need to be synchronously opened at the moment, the door opening motor applies a reaction force on the door knife shaft 23, the door knife 3 which originally keeps an open state is opened and closed, the driving plate I4 and the baffle 7 rotate in opposite directions until the driving plate I4 is abutted against the baffle 7, because the minimum distance between the door knives 3 is smaller than the diameter of the layer gate ball, the door knives 3 can be propped open by the layer gate ball, thereby driving the connecting plate I2 and the driving plate II 13 to rotate, driving the roller 15 to rotate through the rotation of the driving plate II 13, pressure is generated on the locking hook 17, the locking hook 17 is pressed to rotate by taking the hinged point as the circle center, so that the locking hook 17 and the locking piece 25 are unlocked, then the whole synchronous door knife device moves towards the door opening direction, the pair of car doors starts to be opened, the door knives 3 clamp the door balls all the time, and the car doors and the landing doors keep synchronous movement until the pair of car doors and the landing doors are completely opened;

if the door opening motor stops working due to the fact that a control system of an elevator system or a door motor fails, the power supply is cut off, the two door knives 3 can still be closed under the reset action of the second spring, when the landing door ball is located between the two door knives 3, the lock hook 17 can be unlocked, a person can rescue by opening the car door, and if the landing door ball does not fall between the two door knives 3, the lock hook 17 on the synchronous door knife device cannot be unlocked with the lock piece 25, so that the car door cannot be opened through external force, the situation that the car door is opened in a non-landing parking area by a passenger to damage personal safety accidents is avoided, and safety of the device in use is improved;

can also drive commentaries on classics piece 20 and rotate through dragging stay cord 21 with the hand when unblock latch hook 17, rotate through changeing piece 20, drive spacing axle 22 and slide along the sliding port, slide along the sliding port through spacing axle 22, promote latch hook 17 and rotate and carry out the unblock, when preventing that the unexpected condition from taking place, the practicality when the equipment usage has been improved to the personnel of suing and labouring that can be convenient.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
