Working principle of the present invention is as follows:
During shutdown, main lock tongue crosses roller.After main lock tongue crosses roller, main lock tongue pop-up, roller is with main lock
The sliding of tongue and roll.What is generated in mutual movement due to roller and main lock tongue is rolling friction, is not likely to produce abrasion.
During enabling, the relative motion of main lock tongue and roller is the inverse process of aforementioned door closing procedure, is not easy to produce abrasion.Cause
This, equipped with door leaf of the invention switch gate process it is more laborsaving, will not generate noise and abrasion it is smaller.
When door leaf in the present invention is closed with sealed side door, main lock tongue 7 pops up after crossing roller, sequentially passes through third lock
Tonguing is portalled 3-3, the first lock tongue manhole appendix 2-7, and door is lockked, since roller is with what main lock tongue generated in mutual movement
Rolling friction is not likely to produce abrasion.Therefore, equipped with door leaf of the invention switch gate process it is more laborsaving, will not generate and make an uproar
Sound and abrasion it is smaller.Sealing joint strip 11 on transition plates 2-2 is contacted with the 4th stepped plate 5-6 on sealed side door.Sealing joint strip
11 can reduce noise at closing time, and improve the soundproof effect of door.
