[0074] The door handle 510 is pulled outward, and the left door leaf 300 is opened outward. At the same time, the door handle 510 rotates around the handle mounting member 5101, and the locking rope mounting portion 513 moves inward. On the one hand, the first locking rope 580 is pulled downward along the pulley 528, and the first locking pin 530 is pulled downward to slide downward during the downward movement of the first locking rope 580, until the first locking portion 531 of the first locking pin 530 completely slides out of the upper locking hole of the upper pin hole member 231 and slides into the locking column 520; on the other hand, the second locking rope 590 is pulled upward along the pulley 528, and the second locking pin 540 is pulled upward to slide until the second locking portion 541 of the second locking pin 540 completely slides out of the lower locking hole of the lower pin hole member 232 and slides into the locking column 520. At this point, the left door leaf 300 has synchronously completed the two steps of unlocking and opening the door.

[0075] The working process of the left locking piece to achieve synchronous door closing and locking is as follows:

[0076] The left door leaf 300 is initially in an open state, and the locking portion 531 of the first locking pin 530 and the locking portion 541 of the second locking pin 540 extend out of the locking column 520 .

[0077] The door handle 510 is pressed, and the left door leaf 300 is closed inwards. At the same time, the door handle 510 rotates around the handle mounting member 5101, and the locking rope mounting portion 513 moves outwards. On the one hand, the first locking rope 580 is pulled downwards, and the first locking pin 530 is pulled downwards to slide downwards during the downward movement of the first locking rope 580, until the first locking portion 531 of the first locking pin 530 completely slides out of the upper locking hole of the upper pin hole member 231 and slides into the locking column 520; on the other hand, the second locking rope 590 is pulled upwards, and the second locking pin 540 is pulled upwards to slide until the second locking portion 541 of the second locking pin 540 completely slides out of the lower locking hole of the lower pin hole member 232 and slides into the locking column 520.

[0078] When the left door leaf 300 is completely closed, the handle is released and the locking rope installation part 513 is reset. On the one hand, the first spring 522 squeezes the first locking pin 530 to slide upward until the first locking part 531 of the first locking pin 530 completely slides out of the locking column 520 and slides into the upper locking hole of the upper pin hole member 231; on the other hand, the second spring 525 squeezes the second locking pin 540 to slide downward until the second locking part 541 of the second locking pin 540 completely slides out of the locking column 520 and slides into the lower locking hole of the lower pin hole member 232. At this point, the left door leaf 300 has synchronously completed the two steps of closing and locking the door.

[0079] In this embodiment, the right locking member is symmetrically arranged with the left locking member, and its structure, function and working process are completely consistent with those of the left locking member.
