Clutch outer member 5 is secured to the handle pulling part 4, and the clutch outer member 5 is provided with the latch bolt to link with the latch bolt component 2 and stirs
Portion 51；The clutch outer member 5 can by the handle pulling part drive and linked the latch bolt component 2 by latch bolt clicking section 51.
The latch bolt component 2 includes latch bolt, latch bolt connecting rod 22, latch bolt fitting 23, latch bolt cauda 24 and latch bolt tension spring 25；Institute
Latch bolt fitting 23 is stated to be installed in the lock housing 1；The latch bolt connecting rod 22 is connected to the latch bolt fitting 23；The latch bolt connection
In the upper end of the latch bolt connecting rod 22, the latch bolt cauda 24 is connected to the lower end of the latch bolt connecting rod 22；The latch bolt connecting rod
22 are socketed the latch bolt tension spring 25 between the latch bolt fitting 23 and latch bolt；The latch bolt clicking section 51 is set to the latch bolt
Between fitting 23 and latch bolt cauda 24；
Driving column 11 and the master driver detachably installed 6 are additionally provided in the lock housing 1, the driving column 11 is located at institute
It states near latch bolt connecting rod 22,6 one end of the master driver is provided with attachment hole 61 to be movably connected on the driving column 11, another
End is provided with linkage portion to be movably connected on the latch bolt clicking section 51；It is provided on the downside of the linkage portion and presses end 63, it is described
End 63 is pressed to contact with the latch bolt cauda 24；The master driver 6 is fulcrum with the driving column 11, can be dialled with the latch bolt
The drive in dynamic portion 51 and push the latch bolt cauda 24, realize the linkage of the latch bolt.
Specifically, the master driver is class " 8 " font, a linkage cylinder is provided on the latch bolt clicking section 51
511, the slotted hole 62 that a long diameter is more than linkage 511 diameter of cylinder, the linkage cylinder are provided in the linkage portion
It can be slided in the 511 access slotted holes 62 and back and forth in slotted hole 62, pass through setting for link cylinder 511 and slotted hole 62
It sets, simply and efficiently realizes the connection application of the latch bolt clicking section 51 and linkage portion.
Preferably, it is additionally provided with square tongue component 3 in the lock housing 1；The clutch outer member 5 is additionally provided with and the square tongue group
The square tongue clicking section 52 that part 3 links；, the square tongue component includes main square tongue 31 and square tongue pulling part 32, and the square tongue pulling part 32 fills
It is connected in the lock housing 1, the square tongue pulling part 32 is connect with the main square tongue 31, and the square tongue pulling part 32 is stirred with the square tongue
Portion 52 connects；Lockset is by the setting of latch bolt component 2, and further application has square tongue component 3, more effectively ensures the work(of lockset
It can property and stability.
Its operation principle is as follows：
As shown in Figures 2 to 5, the lock housing 1 corresponds to the latch bolt and is provided with inclined tongue hole 13, and the corresponding main square tongue 31 is set
It is equipped with square bolt hole 14；When the latch bolt that the latch bolt component 2 of lockset is applied is short latch bolt 211, when the door handle is turned, the handle is dialled
Part 4 drives clutch outer member 5 to push the latch bolt cauda 24 with latch bolt clicking section 51, to drive latch bolt connecting rod 22 will be described short oblique
For tongue 211 through being reduced in lock housing 1 under inclined tongue hole 13,211 upper end of short latch bolt flushes in the lock housing 1；The handle pulling part 4 goes back band simultaneously
Dynamic clutch outer member 5 stirs the square tongue pulling part 32 with square tongue clicking section 52, to which the main square tongue 31 that links under square bolt hole 14 through being reduced to
In lock housing 1,31 upper end of main square tongue flushes in the lock housing 1；Complete the unlatching step of lockset.
And when the latch bolt of the latch bolt component 2 of lockset application is changed to long latch bolt 212, by the installation of master driver 6 to lock
In tool；It by above-mentioned preset door-opening mode, turns the handle to equal angular, the main square tongue 31 under square bolt hole 14 through being reduced to lock
When making 31 upper end of main square tongue concordant with lock housing 1 in shell 1, which drives the main transmission by latch bolt clicking section 51
Part 6 is further to push the latch bolt cauda 24, to drive latch bolt connecting rod 22 to further pull on down the long latch bolt 212
Contracting so that the stroke distances of long latch bolt 212 increase, and makes long latch bolt 212 synchronize concordant retraction in lock housing 1, completes lockset
Open step.
Preferably, which is short latch bolt 211 in application, the lock housing 1 corresponds to the clutch outer member 5 in latch bolt fitting 23
Limited block 12 is provided between latch bolt cauda 24；By the setting of limited block 12, make the clutch outer member 5 in latch bolt cauda 24
When driving lower reset, position without departing from；Ensure that the reset position of clutch outer member 5 is accurate, is caused to avoid because of reset error
The case where lockset fails.
Preferably, as shown in Fig. 4 to Fig. 8, when lockset is long latch bolt 212 in application, being arranged on the upside of the linkage portion limited
Position end 64, relatively described 23 downside of latch bolt fitting of the positive stop end 64 work as the latch bolt tension spring 25 and are in normal to be concordantly arranged
When state, the positive stop end 64 is contacted with the latch bolt fitting 23；The latch bolt cauda 24 resetted because the latch bolt tension spring 25 is elastic
The linkage clutch of the master driver 6 outer member 5 is driven to reset；By the setting of positive stop end 64, the limit of the master driver 6 is limited
End 64 is concordant by being connected to the latch bolt fitting 23, and the reset position to ensure clutch outer member 5 is accurately required, is missed to avoid because resetting
Difference and the case where cause lockset to fail.
Preferably, the latch bolt cauda 24 is provided with the linkage portion for limiting the master driver 6 and pushes the oblique of angle
Boss 241；By the setting of inclined platform 241, when the clutch outer member 5 drives master driver 6 to push the latch bolt cauda 24
When, limit the pushing angular range of the linkage portion；Avoid master driver 6 because push angle it is excessive due to cause master driver 6 with
Driving column 11 is the direction of rotation dynamics loss of fulcrum, keeps master driver 6 stuck in 24 position of latch bolt cauda, leads to latch bolt component
2 cannot reset, and lockset is enabled to fail；Specifically, the angle of inclination setting of the latch bolt cauda 24 relatively of the inclined platform 241
It is 20 degree；Maximum is no more than 45 degree.
The foregoing is merely the preferred embodiment of the present invention not to depart from this for those skilled in the art
Under the premise of the implementation principle of invention, it can still modify to the embodiment, and corresponding modification also should be regarded as this hair
Bright protection domain.
