13 and interior thumb wheel 12 be rotatably installed in respectively unlock 11 two sides of thumb wheel, interior thumb wheel 12 and outer thumb wheel 13 are respectively used to install interior door knob
And outer door knob (interior door knob and outer door knob belong to the prior art, are not drawn into attached drawing), unlock thumb wheel 11 are used for solving locking key 8
Contact.
Need to illustrate attached drawing 5 is that outer thumb wheel 13 and interior thumb wheel 12 only fit together, and there is no appoint for the two
What structure links together, the two be can relatively rotate completely with disengage.
It further include gear plectrum 14 and transmission gear 15 as shown in attached drawing 1,2,3,4 and 5, the rotation of gear plectrum 14 is arranged
On interior thumb wheel 12, gear plectrum 14 is meshed together by transmission gear 15 with main lock gear 17, transmission gear 15 and main lock
Tongue component 5 is combined together, and transmission gear 15 is moved by the main bolt component 5 of rotate driving；When interior thumb wheel 12 rotates band movable tooth
When taking turns plectrum 14 and rotating, the closing piece part 501 of main bolt component 5 to outside lock housing 1 from moving in lock housing 1；Main lock gear 17 and biography
Moving gear 15 directly or indirectly meshes together.
Transmission gear 15 is meshed together with main lock gear 17 by main lock thumb wheel 16 indirectly in this case.
When be located at it is indoor at closing time, when 4 failure of motor, main lock tongue can be driven to move by rotation Internal handle, specifically
It is contrary with when unlatching sliding-tongue 9 to rotate inner handle direction, is to rotate counterclockwise if it is sliding-tongue 9 is opened, then at this time
Then to rotate clockwise could open bolt component.
It further include unlock thumb wheel torsional spring 1003 as shown in attached drawing 1,2,3,4 and 5, unlock thumb wheel 11 is driven by own rotation
Dynamic solving locking key 8 is disengaged with sliding-tongue 9, and the setting of unlock thumb wheel 11 is in lock housing 1, and unlock thumb wheel torsional spring 1003 is for driving unlock
Thumb wheel 11 resets after rotating.
It further include output gear 3 and tumbler gear 18 as shown in attached drawing 1,2,6,7 and 8, output gear 3 is installed on motor 4
On, output gear 3 is meshed together by tumbler gear 18 with main lock gear 17.
It further include main lock thumb wheel 16 as shown in attached drawing 1,2,3,4 and 5, main lock thumb wheel 16 is rotatably dispose in main lock gear 17
Interior, main lock gear 17 is meshed together by main lock thumb wheel 16 with transmission gear 15.
With in main lock gear 17, main lock gear 17 drives main lock thumb wheel 16 to rotate when rotating for the specific main setting of lock thumb wheel 16,
The main rotation of lock thumb wheel 16 band nutating gear 15 rotates.
Key inserting apparatus is installed in another effect of main lock thumb wheel 16, has the key inserting apparatus can to use key
It is moved to drive main bolt component 5 and sliding-tongue 9.
Key inserting apparatus is used to cooperate with key, and rotation key can drive main bolt component 5 or sliding-tongue 9 to move.
It further include main lock thumb wheel torsional spring 1004 as shown in attached drawing 1 and 2, the main lock thumb wheel torsional spring 1004 is set to lock housing 1
