The elastic element pressing plate device 61 comprises an elastic element pressing plate mounting plate 62, a pressure spring base 64 and a conical shaft 65. The elastic element pressing plate mounting plate 62 is a 90-degree bent steel plate and comprises a front face and a side face, the front face is provided with 1 round hole, an M5 threaded hole of the second swing rod 4 is formed in the round hole, the side face of the elastic element pressing plate mounting plate 62 is provided with a round hole with the diameter of 5, the pressure spring base 64 is riveted on the round hole at a high speed, the pressure spring base 64 is a round face, the round face is parallel to the side face of the elastic element pressing plate mounting plate 62, the pressure spring base 64 is provided with a conical shaft 65, the axis of the conical shaft is concentric with the circle center of the pressure spring base 64, and the length of the conical shaft. The side of the door vane mounting seat horizontally opposite to the elastic element pressure plate mounting plate 62 is provided with an M5 threaded hole, and a M5 screw is mounted on the threaded hole on the side of the door vane mounting seat, and the length of the screw can be within 12 to 16 mm. When the door is completely closed, the angle between the side surface of the elastic element pressure plate mounting plate 62 and the side surface of the door knife mounting base 1 is adjusted to be 10 degrees, one end of the pressure spring 63 is sleeved on the screw of the M5, and the other end of the pressure spring is sleeved on the conical shaft, so that the pressure spring 63 is ensured not to be separated from the conical shaft 65 and the screw 60 of the M5 in the whole maximum swinging process of the first movable blade 2. In the operational swing stroke of the first movable blade 2, the surface of the pressure spring base 64 of the elastic element pressure plate is always in contact with the pressure spring 63 to store or release energy by deformation of the pressure spring 63, and when the pressure spring 63 releases energy, the first movable blade 2 is pushed to swing in the door opening direction, and the first movable blade 2 swings in the door closing direction to store energy in the pressure spring 63.

The car door has full-closed holding force, which can be provided by motor force or other mechanical devices. When the door is completely closed, even if the first movable blade 2 is pushed towards the opening direction by the pressure spring 63 or the gravity of the mechanism, the first swing rod bulge 13 is abutted by the lower end of the blocking part 9 under the action of the completely closed retaining force of the car door, and the first movable blade 2 cannot swing towards the opening direction.

As shown in fig. 7-8, when the car is normally opened in the unlocking area, there are landing door unlocking roller 28 and landing door linkage roller 29 between the first movable blade 2 and the second movable blade 27, and the outer diameters of the landing door unlocking roller 28 and the landing door linkage roller 29 are generally the same, and after the landing door unlocking roller 28 swings for a certain unlocking stroke, the landing door unlocking roller cannot swing, and the centers of the landing door unlocking roller 28 and the landing door linkage roller 29 are on a vertical line. When the sedan-chair door is opened, as before, first movable blade 2 is toward the swing of the direction of opening the door, and the sedan-chair door is opened simultaneously, and first movable blade 2 swings and contacts layer door unblock gyro wheel 28 behind one section horizontal distance K, continues to open the sedan-chair door, and first movable blade 2 continues the swing and makes layer door unblock gyro wheel 28 to the swing of the door lock direction of opening the layer, and the gyro wheel of unblanking of layer door is unable to swing up to this moment, and layer door unblock gyro wheel 28 and layer door linkage gyro wheel 29's center is on a vertical line this moment. At this time, the acceleration force to push the landing door is much larger than the driving force of the first movable blade 2. The driving force of the first movable blade 2 is the gravity of the double-rocker mechanism of the first movable blade 2, and may be the thrust of the pressure spring 63. When the car door is opened, the first movable blade 2 swings in the door closing direction against the driving force under the action of the acceleration reaction force for pushing the landing door. When the car door continues to move, the first movable blade 2 contacts the first limiting device 18 under the swinging action of the reverse thrust of the landing door, the car door cannot swing continuously, the door opening stroke can be defined as S, the acceleration force for pushing the landing door is provided by the first limiting device 18, and the car door and the landing door start to be linked.

When the door is opened, the second movable blade 27 starts to swing in the door closing direction by the second movable blade movement driving device 35, and the horizontal displacement of the second movable blade 27 in the door closing direction after the door is opened by the second movable blade movement driving device 35 is S2: s2 ═ S1-D.

In the above formula, S1 represents the distance from the working surface of the first movable blade 2 to the working surface of the second movable blade 27 when the door is fully closed, D represents the outer width of the landing door unlocking roller 28 and the landing door interlocking roller 29 in the horizontal direction, and D represents the outer diameter of the landing door unlocking roller or the landing door interlocking roller according to the conventional technique.

In actual design, according to the setting, when the car door is fully closed, the horizontal clearance P between the working surface of the first movable blade 2 and the outer circle of the roller at the upper part of the landing door lock is 9 mm. Through the design of the blocking part 9, the design of the first swing rod 3, the position relation between the first rotary center 36 and the first movable blade 2 on the first swing rod 3, the position relation between the boss 13 and the first swing rod rotary center 36 on the first swing rod 3, and the position relation between the blocking part 9 and the first swing rod rotary center 36, the unlocking linkage process of the car door to the landing door in the unlocking area is as follows:

when the car door stroke is 4mm, the horizontal swinging horizontal stroke of the first movable blade 2 is 5mm, and the working surface of the first movable blade 2 just contacts with the excircle of the landing door unlocking roller 28.

When the car door stroke is 7mm, the horizontal swinging horizontal stroke of the first movable blade 2 is 9mm, the first movable blade 2 enables the excircle of the landing door unlocking roller 28 to rotate to the position with the maximum unlocking stroke, the landing door unlocking roller 28 and the center of the lower landing door lock roller 29 are on the same vertical line, and the upper landing door lock roller cannot rotate continuously. At this time, the reaction force of the landing door acceleration force is larger than the sum of the first movable blade mechanism gravity and the horizontal direction force of the pressing spring 63. When the car door continues to open, the first movable blade 2 starts to swing in the opposite direction to the door closing direction.

When the car door stroke is 16mm, the first movable blade 2 rotates towards the door closing direction and contacts the first limiting device 18, the horizontal displacement of the first movable blade 2 compared with the initial time is also 16mm, and then the car door and the landing door are opened and closed in a linkage mode. During the opening of the car door, the second movable blade 27 is continuously swung in the door closing direction under the control of the second movable blade motion control device 35, and the final swing horizontal stroke is S1-D, and the upper and lower rollers of the landing door are clamped.

When the lift car is in an unlocking area and in emergency rescue, the landing door is opened by using the triangular key, when the landing door is opened, the lower roller 29 of the landing door lock firstly contacts the second movable blade 27, the second movable blade 27 pushes the lift car door to be opened, when the lift car door is opened, the first swing rod 3 rotates anticlockwise, the first movable blade 2 swings towards the door opening direction, and when the first movable blade 2 swings until the first movable blade 2 contacts the landing door linkage roller 29

The amount of horizontal swinging stroke of the first movable blade 2 in the door opening direction is S4: s4 ═ S1-D.

In the above formula, S1 represents the distance from the working surface of the first movable blade 2 to the working surface of the second movable blade 27 when the door is fully closed, where D represents the outer width of the landing door unlocking roller and the landing door interlocking roller in the horizontal direction, and D represents the outer diameter of the landing door unlocking roller or the landing door interlocking roller, where D represents 46 mm.

When the car is in the unlocking area, the car door drives the landing door to be linked, and when the car door moves in a closing mode, the second movable blade 27 swings in the door opening direction under the control of the second movable blade action driving device 35 to release the thrust on the landing door linkage roller. In the prior art, the second movable blade 27 releases the thrust to the landing door linkage roller when the car door is closed by about 90mm, and the landing door is closed under the action of forced door closing force and initial kinetic energy. Two situations can occur after the door is closed:
