The utility model discloses an operation process of elevator switch door as follows:

referring to fig. 6, when the elevator is closed in place, the slider 7 is located at the rightmost side of the guide rod 8, that is, at one end of the guide rod 8 close to the fixing plate 10, the extending portion 92 of the rotating rod 9 abuts against the fixing plate 10, the notch 91 of the rotating rod 9 is not clamped with the second shaft portion 72, the oscillating rod 5 rotatably connected with the slider 7 falls, the traction rope 6 is not hooked, the latch hook 4 is clamped in the floor door lock at this time, and the door vane device 200 is locked. At this time, the elevator can continue to move up and down or move to a certain floor to prepare for opening the door. Referring to fig. 7 and 8, when the elevator is opened gradually from the closed state, when the car is just moving to a certain floor, the two door balls 3018 of the landing door are located within the length range of the left knife arm 21 and the right knife arm 22, but do not clamp the door balls 3018 (as shown in fig. 7). Along with the transmission of the synchronous belt 109, the sliding block 7 is driven to move from the right side to the left side of the guide rod 8 until the notch 91 is clamped with the second shaft part 72, at the moment, the sliding block 7 does not move any more, and in the process that the sliding block 7 moves from the right side to the left side, the swinging rod 5 is driven to rotate, so that the swinging rod 5 hooks the traction rope 6 upwards, the lock hook 4 is lifted upwards, the lock hook 4 is separated from the landing door lock, and the door vane device 200 is unlocked; the rotation of the swing link 5 will also drive the upper swing arm 31 to rotate, and further drive the left knife arm 21 and the right knife arm 22 to move toward the direction of approaching each other until the left knife arm 21 and the right knife arm 22 clamp the two gate balls 3018 on the landing door (as shown in fig. 8). Subsequently, in a state that the sliding block 7 cannot slide continuously, the synchronous belt 109 drives the whole door vane device 200 to move leftwards, and in the process, as the left knife arm 21 and the right knife arm 22 are clamped with the door ball 3018, the landing door, the left door panel 105 and the right door panel 106 (car door) are opened gradually at the same time until the door is opened in place.

When the elevator is closed by the door opening state gradually, drive whole door knife device 200 through the transmission of hold-in range 109 earlier and move gradually rightwards, slider 7 and notch 91 are still in the joint state this moment, when door knife device 200 moves to extension 92 of dwang 9 and touches fixed plate 10 and looks butt with it, the tip that dwang 9 offered notch 91 can upwards lift and make notch 91 can't continue to joint with second shaft portion 72, at this moment, under the continuous transmission effect of hold-in range 109, can drive slider 7 and move to the right side by the left side of guide bar 8, the removal of slider 7 can drive pendulum rod 5 and rotate, the tip that makes pendulum rod 5 and haulage rope 6 be connected falls gradually, thereby make latch hook 4 fall and with the locking of layer door lock, the elevator is closed the door and targets in place. The rotation of the swing link 5 also drives the upper swing arm 31 to rotate, and further drives the left knife arm 21 and the right knife arm 22 to move in the direction away from each other until the left knife arm 21 and the right knife arm 22 release the gate ball 3018. The car can now be moved up or down.

Referring to fig. 9, when the elevator is in failure and the car is close to the landing door, the rescue worker can directly pull the unlocking rope 12 in the car to drive the unlocking matching member 11 to slide in the lock groove 45, and further drive the locking hook 4 to rotate, so that the locking hook 4 is lifted upwards from the fixed hook, the unlocking of the door vane device 200 is realized, and the rescue worker can open the car door.
