The car door lock device which is independent of the door knife is needed to realize the function in the early days, and a special collision bow is added on the side of the landing door device, so that high requirements are required for production and manufacturing and site installation, a large amount of complaints are caused, and the operation of enterprises is influenced to a certain extent. So the prior art generally adopts an integrated car door lock door knife, which realizes the function of the car door lock on the original door knife without increasing the requirement on the landing door side. In addition, the current standard has a requirement for locking the car door after the non-flat floor is powered off, but the action state of the car door lock body is not defined. The car door lock device in the industry can act after the power is off, so that the blade can strike the gate ball of the door lock of the damaged landing door after the power is on again or when the jigger rescue returns to the flat landing, and serious potential safety hazards exist.

The first blade rotating arm 53 and the second blade rotating arm 54 are respectively hinged and fixed on the front surface of the U-shaped plate 11, the first blade 51 and the second blade 52 are respectively hinged with the first blade rotating arm 53 and the second blade rotating arm 54 to form a parallelogram connecting rod structure, the first blade rotating arm 53 is connected with one end of the second connecting arm 55, and the other end of the second connecting arm 55 is connected with the other end of the connecting shaft 24.
The plate 61 is a planar plate, and grooves at two ends of the plate 61 are respectively inserted into grooves of the release arm assembly 3 and the latch hook assembly 4. The snap end of the guide shaft 62 is inserted into the groove of the rotating plate 21.
The rotating plate assembly 2 is connected with a transmission belt of an elevator car door device, and the elevator car door device drives a synchronous belt shaft 23 of the rotating plate assembly 2 to move.
The release arm assembly 3 is lifted and unlocked by a release plate 7 fixed on the elevator door device, so that the rotating plate assembly 2 can act, and a spring 63 in the release device 6 starts to act, and the elevator door device is pushed to apply a holding force in the closing direction by the invention. The door closing maintaining force is provided at the initial stage of the rotating plate 21, and is also eliminated when the timing belt shaft 23 of the rotating plate assembly 2 rotates to the right of the first slot hole 111 of the U-shaped plate 11. While the release arm assembly 3 also provides a door closing retaining force against the door closing side of the release plate 7. The two-stage holding force of the system solves the phenomenon of 'secondary door closing', and can reduce the load of the driving system of the elevator car door device after the door is closed in place.
When the starting position of the synchronous belt shaft 23 of the rotating plate assembly 2 is at the left side of the first slot hole 111 of the U-shaped plate 11, the guide shaft axis 65 is positioned above a datum line 66 formed by connecting the center of the fixed shaft bearing of the rotating plate assembly 2 with the center of the circular hole of the plate 61. When the timing belt shaft 23 is driven to the right side of the first slot hole 111 of the U-shaped plate 11 by the elevator car door device, the locking end of the guide shaft 62 rotates around the groove of the rotating plate 21, and the cutter arm assembly 5 is driven to act by the connecting shaft 24. The guide shaft axis 65 eventually passes through the reference line 66 to below the reference line 66, and the guide shaft axis 65 forms an angle of greater than 0 ° with the reference line 66. When the guide shaft axis 65 is located below the datum line 66, the force of the spring 63 released by accidental power failure cannot be released, so that the cutter arm assembly 5 cannot act, and the potential safety hazard that the blade bumps against a damaged landing door lock gate ball after the elevator is electrified again or when a jigger rescue returns to a flat bed is eliminated.
The state of the invention in the process of opening and closing the door in the flat layer area is as follows: the rotating plate assembly 2 is blocked by the release arm assembly 3 and cannot rotate, so that the synchronous belt shaft 23 stays at the left side of the first slot hole 111 of the U-shaped plate 11, the connecting shaft 24 cannot move downwards, and meanwhile, the door ball with the door lock at the door side of the elevator landing zone acts on the first blade 51 and the second blade 52, and the two blades are limited not to excessively stretch outwards, so that the second connecting arm 55 cannot move upwards. The position of the connecting shaft 24 is limited by the rotation plate assembly 2 and the cutter arm assembly 5, and finally acts on the latch hook assembly 4 to lift the head of the latch hook assembly to be in an unlocking state. The guide shaft axis 65 of the release device 6 is now above the reference line 66.
The process of closing the door in place comprises the following steps: the release arm assembly 3 is acted upon by the release plate 7 at the door closing end, and finally the release shaft 31 is lifted up to the door closing side of the release plate 7. The rotating plate assembly 2 is not blocked by the releasing arm assembly 3, the synchronous belt shaft 23 rotates from the left side of the first slot 111 of the U-shaped plate 11 to the right side of the first slot 111, the first connecting arm 22 moves downwards during the rotation, and the connecting shaft 24 moves along the second slot 112 of the U-shaped plate 11. In addition, the second connecting arm 55 moves along with the connecting shaft 24, so that the first blade 51 and the second blade 52 are folded, and meanwhile, the locking hook assembly 4 is separated from the limitation of the connecting shaft 24, and the head of the locking hook assembly 4 is downwards reached to the locking position under the action of gravity and the spring 63.
At this time, if the two blades are subjected to the force in the folding direction again, the second connecting arm 55 will act, but the rotating plate 21 cannot act, and the first connecting arm 22 can only rotate with the connection point of the first connecting arm and the rotating plate 21 as the base point, so that the connecting shaft 24 is pushed to move towards the latch hook assembly 4, and the head of the latch hook assembly 4 is lifted up to be in the unlocking state. The elevator door lock can lock the elevator door outside the elevator leveling area, and can unlock the door plate in the elevator car or outside the elevator door during leveling, help rescue, and finally realize the function of the elevator door lock.
After the door is closed in place, the plate 61 is pushed by the force of the spring 63, so that the release arm assembly 3 rotates, and the release shaft 31 pushes the release plate 7 to generate a holding force in the closing direction. Meanwhile, the synchronous belt shaft 23 is driven by the elevator car door device, and rotates from the left side of the first slot hole 111 of the U-shaped plate 11 to the right side of the first slot hole 111 after overcoming the acting force of the spring 63, and an acting force which is pushed to the door closing direction is generated in the process, and the two acting forces jointly solve the phenomenon of secondary door closing. Meanwhile, during the door closing operation of the car door locking knife, the synchronous belt shaft 23 rotates from the left side of the first slot 111 to the right side of the first slot 111, and the guide shaft axis 65 of the release device 6 moves from above the reference line 66 to below the reference line 66. No matter whether the elevator is electrified or not, acting force is generated to enable the rotating plate assembly 2 to rotate, and the synchronous belt shaft 23 is guaranteed to be on the right side of the first slotted hole 111, so that two blades are guaranteed not to generate misoperation due to the fact that the elevator is powered down, and the potential safety hazard that the blades strike and damage door lock balls of the landing door after the elevator is powered up again or when a jigger is used for rescuing and returning to a flat landing is eliminated.
