The operating principle of the elevator connecting rod car door lock device in the embodiment comprises the following steps:

as shown in fig. 2-3, when the car is in the unlocking area and receives a door opening command, the motor moves to move the synchronous belt towards the door opening direction, the starting block 6 rotates towards the door opening direction around the starting rod under the action of the synchronous belt, and drives the door knife arm assembly 2 to fold inwards to clamp a landing door ball through the connecting rod assembly 4, and unlocks the landing door lock, through the action of the connecting rod assembly 4, one end of the lock hook connecting rod 5 is pressed rightwards and upwards, the connecting rod assembly 4 drives the lock hook connecting rod 5 to swing, so that the lock hook connecting rod 5 drives the tail end of the lock hook 3 to rotate downwards, the hook end of the lock hook 3 rotates upwards, the car door lock hook 3 is unlocked, and the switch contact 8 is driven to move towards the door opening direction (the switch contact 8 moves rightwards) on the door knife bottom plate 1 to be separated from the switch socket 9, so as to realize unlocking, and the car normally opens the door.

As shown in fig. 1, when the car receives a door closing command in an unlocking area, the starting rod is driven by the motor to move in a door closing direction, the rolling bearing 22 on the swing link 19 touches the curve plate fixed on the bottom plate of the door machine, so that the swing link 19 rotates and drives the limit bearing 21 to separate from the limit groove 25 on the starting block 6 and move on the limit curved surface of the starting block 6, the starting block 6 starts to rotate, and drives the door knife arm component 2 to open outwards through the connecting rod component 4, at the moment, the rotating component 18 is in a free state, the lock hook 3 is in a locking state under the influence of the self gravity and the elastic component 10, specifically, the hook end of the lock hook 3 rotates downwards through the self gravity and the potential energy accumulated by the elastic component 10, and the switch contact 8 is driven to move to the contact switch socket 9 on the door knife bottom plate 1 in the door closing direction (the switch contact 8 moves leftwards), so that locking is realized, and the car is normally closed.

In this embodiment, as shown in fig. 2-3, when the car is in the unlocking area and the door is opened from the car, the car door is forcibly moved to the door opening direction by external force until the right door knife arm 30 touches the landing door ball, the right door knife arm 30 expands outwards under the resistance of the landing door ball, so that the first connecting block 31 and the second connecting block 32 rotate clockwise and drive the left door knife arm 29 and the right door knife arm 30 to rotate, one end of the lock hook connecting rod 5 is extruded and acted to the right upper side through the action of the connecting rod component 4, the connecting rod component 4 drives the lock hook connecting rod 5 to swing, the lock hook connecting rod 5 drives the tail end of the lock hook 3 to rotate downwards, the hook end of the lock hook 3 rotates upwards, the car door lock hook 3 is unlocked, and the switch contact 8 is driven to move to the opening direction (the switch contact 8 moves rightwards) on the door vane bottom plate 1 to be separated from the switch socket 9, so that unlocking is realized, and the lift car opens the door.

In this embodiment, as shown in fig. 4, when the car is in the unlocking area and the door is taken off from the outside of the car, the triangular key is used to unlock the landing door, so that the landing door moves in the door opening direction until the left door knife arm 29 touches the landing door ball, the left door knife arm 29 expands outwards under the resistance of the landing door ball, the first connecting block 31 and the second connecting block 32 rotate clockwise and drive the left door knife arm 29 and the right door knife arm 30 to rotate, one end of the lock hook connecting rod 5 is extruded and acted to the right upper side through the action of the connecting rod component 4, the connecting rod component 4 drives the lock hook connecting rod 5 to swing, the lock hook connecting rod 5 drives the tail end of the lock hook 3 to rotate downwards, the hook end of the lock hook 3 rotates upwards, the car door lock hook 3 is unlocked, and the switch contact 8 is driven to move to the opening direction (the switch contact 8 moves rightwards) on the door vane bottom plate 1 to be separated from the switch socket 9, so that unlocking is realized, and the lift car opens the door.

In this embodiment, as shown in fig. 5, the car is in the non-region of unblanking, when the motor opened the door by mistake, the motor action made the hold-in range to the direction motion that opens the door, the hold-in range drove the actuating lever, the actuating lever drove actuating block 6 and rotates, make first link block 31 anticlockwise rotation, because there is not layer croquet in the middle of this moment, left side door tool arm 29 and right door tool arm 30 continue inside clamp tightly, the one end of latch hook connecting rod 5 did not receive the effect of upper right extrusion force, latch hook connecting rod 5 keeps the free state this moment, latch hook 3 still is in the locking state, still keep the locking state of normally closing the door with the switch support of integration on the door machine bottom plate. Specifically, the hook end of the latch hook 3 is maintained in a downward state by its own weight and potential energy accumulated by the elastic member 10, so that the switch contact 8 is maintained in contact with the switch socket 9, and is continuously in a locked state.

The car is in the non-region of unblanking, when taking off the door in the car, the motor does not move, the actuating lever, actuating block 6 and linkage plate also remain motionless, door link plate drives door sword bottom plate 1 and moves to the direction of opening the door when taking off the door, whole connecting rod sedan-chair door lock device is whole to the direction of opening the door and move to latch hook 3 and catch the switch fixed plate of fixing on the door machine, owing to in the non-region of unblanking, left side door tool arm 29 and right door tool arm 30 all can't contact layer door ball, so left side door tool arm 29 and right door tool arm 30 all do not move, the door link plate continues to move to the hook and catch the hook plate of fixing on the door machine to the direction of opening the door, the interval of opening the door is less than 50mm, satisfy the national standard requirement.

The car is in the region of unblanking, when the car opens the door outward, earlier with the triangle key with the door unblock, make the layer door move to opening the door direction and open completely, and manual pull-down rescue rope, rescue rope fixed part downstream drives urgent unlocking sheet 33 and rotates along clockwise, after urgent unlocking sheet 33 overcomes the torsion of urgent unblock torsional spring, one end promotes locating part 15 that latch hook 3 upper end set up, make latch hook 3 rotate along the anticlockwise, realize the unblock of sedan-chair door, manual taking off the sedan-chair door again, after releasing the rescue rope, urgent unblock torsional spring release torsion makes urgent unlocking sheet 33 rotate along the anticlockwise, the hook end of latch hook 3 passes through the potential energy automatic re-setting that elastic component 10 gathered, keep the state of locking.

Compared with the prior art, the elevator connecting rod car door lock device provided by the embodiment can ensure that the mechanical part is locked and the safety of the electric circuit is verified simultaneously, so that the car door lock is simple in structure, convenient to install and debug, capable of reducing the maintenance difficulty and the cost of an elevator, capable of improving the reliability and safety of the car door lock, and capable of enabling the opening and closing doors of various conditions to be simpler, more reliable and safer through the door opening and closing mode of linkage.
