Make axial-rotation for outer lock core.
Another group of lock tooth on the key and the second shell fragment coordinate, after key insert, and the second shell fragment is designed from interior by shooting
The cylindrical upper stretching of core, because lock tooth high and low position is different, also there is difference in the height that the second shell fragment and each pellet stretch out,
This different height is just corresponding with outer lock core shell fragment.
Outer lock core shell fragment hole 2-3 is set on outer lock core wall；Outer lock core shell fragment 2-4 is pin structure, and radially penetrates external lock
Core shell fragment hole 2-3, sets the second side column croze 2-5 in the middle part of pin, and the second side column croze corresponds to the second side column bolt
5.In pin end, shifting block 2-7 is set.According to design, wherein, the second side column croze and shifting block on each outer lock core shell fragment
2-7 distances are different, so, in order that the second side column bolt 5 is dropped into the second side column croze 2-5 and (owned simultaneously
The second side column croze on outer lock core shell fragment is arranged in a line below the second side column bolt), each outer lock core shell fragment row
The distance walked should be different.
When internal cylinder makees axial-rotation relative to outer lock core, certain angle is rotated to, makes the second shell fragment and outer lock core bullet
Piece contacts and toggles it to the shifting block 2-7 of outer lock core shell fragment, outer lock core shell fragment is moved a segment distance, due to the height of the second shell fragment
Different, so the distance of outer lock core shell fragment movement is also differed, by design, each single outer lock core movement it is different away from
From rear, the second side column croze of outer lock core shell fragment is just set to arrange in a line, the second side column bolt 5 drops into the second side column

The combination of 3rd pellet includes the spring and the 3rd pellet group being arranged in the pellet mounting hole 2-8 of outer lock core afterbody the 3rd
The epimere pellet of conjunction.When lockset is in locking state, the hypomere pellet of the 3rd pellet combination is entirely fallen in the 3rd marble hole
In 1-5, epimere pellet makes internal cylinder relatively outer through penetrating into internal cylinder after the 3rd pellet mounting hole, collar 1-1
Lock core rotates.After key is inserted, the 3rd group of lock tooth combines 1-3 cooperations with the 3rd pellet, the combination of the 3rd pellet is up moved,
The height that the 3rd pellet combination epimere pellet is corresponded to because the 3rd group of lock tooth is different with height is different, and it is upper that the 3rd pellet is combined
Inner surface and internal lock core outer surface junction in the collar are just unified in lower two sections of pellet joints, so that internal cylinder is jacketed
Ring can rotate relative to outer lock core.In addition, when outside inner surface and internal cylinder of the two sections pellet joint higher than the collar
Surface junction, or two sections pellet joint, in collar through hole, internal cylinder can not all rotate.
When the joint for the two sections pellet that the 3rd pellet is combined be located at set ring inner surface and internal cylinder outer round surface it
Between when, internal cylinder can be rotated, and the collar is static, internal cylinder rotate an angle after can make the 3rd pellet combine epimere pellet
Fall in locked blind hole, internal cylinder is opened by locked still what technology that can not carry out again.In addition to forcible entry property is opened, it is impossible to appointed
What is opened.
So just it can prevent unlocking staff from pellet is reached open position one by one by the way of pellet is persistently stirred and opening
Lockset is opened, because during dialling bullet, the joint of the two sections pellet of the 3rd pellet combination can be dialled in set ring inner surface
Between internal cylinder outer round surface.Unlocking staff can take for rotating internal cylinder, after an angle is rotated, immediately
It is locked.
In the present embodiment, because the height and the restricted width of lockhole of shaped as key bit, moved down in the combination of the 3rd pellet
Dynamic position can not ether it is big, therefore the collar thickness can not ether it is thick, the set ring thickness in the present embodiment is less than 1mm.In order to
Make the 3rd pellet combination more delicately walked in the through hole of the collar, so the aperture design of through hole be approximately more than the 3rd marble hole or
/ 3rd of blind hole.Difficulty is opened in order to increase technology, the present embodiment designs four groups of collars.More than four groups can also be designed.
In order that lock core rotate a less distance all may be locked, the blind hole of both sides and the 3rd pellet pitch of holes may design compared with
It is small, about 2.5 to 3mm.
The second antitheft locking mechanism on the present invention：
When internal cylinder makees axial-rotation relative to outer lock core, certain angle is rotated to, makes the second shell fragment and outer lock core bullet
Piece contacts and toggles it to the shifting block 2-7 of outer lock core shell fragment, outer lock core shell fragment is moved a segment distance, due to the height of the second shell fragment
Different, so the distance of outer lock core shell fragment movement is also differed, by design, each single outer lock core movement it is different away from
From rear, the first side column croze of outer lock core shell fragment is just set to arrange in a line, the second side column bolt 5 drops into the first side column
In croze 2-6 processed, outer lock core is set to rotate unlatching lockset.If but opened using external force, there is the walking of outer lock core shell fragment inclined
Difference, a minimum distance of walking outer lock core shell fragment, anti-theft billiards will be fallen in antitheft neck more, make the second lock core locked,
Any unlatching can not be carried out again, can only be dismantled.
The foregoing is merely illustrative of the preferred embodiments of the present invention, all in this practicality not to limit the utility model
