Part 30 is removably fixed on lock core 70；Housing 40 has through hole, and dead bolt 60 is installed in sliding part 50 near the one of through hole
On end and slide and be arranged in through hole；Sliding part 50 is slidably installed on lock core 70；Lock core 70 is pivotally pacified
Loaded on housing 40；Extension rod 31 is fixedly arranged on first end；Sliding part 50 is provided with the screens breach for the second end reciprocally swinging, the second end
Stretch into screens breach and offseted for two wall bodies 54 relative with screens breach；Flexible member 20 is used to provide drive to revolving part 30
The elastic stress for making the second end be offseted with two wall bodies 54.
Flexible member 20 is installed on revolving part 30, and when revolving part 30 is rotated by external force, flexible member 20 is by receiving pressure
Power is converted to release pressure, and the pressure for being discharged is that flexible member 20 is used to order about the second end and two wall bodies to the offer of revolving part 30
54 elastic stresses for offseting, when rotating lock core 70, under elastic stress effect, the second end and two wall bodies 54 offset and drive slip
Part 50 is slided；When the second end drives sliding part 50 towards near the sliding of the direction of through hole, until gathering sill 53 is away from the one of through hole
When end is supported with lock core 70, dead bolt 60 keeps being in locking state；When the second end drives sliding part 50 away from the side of through hole
To sliding, until when gathering sill 53 is supported near one end of through hole and lock core 70, dead bolt 60 keeps being in unlocking condition；In elasticity
In the presence of element 20, the second end remains and is offseted with any one wall body 54 of two wall body 54 of screens breach, orders about gathering sill
53 two ends maintain one end and are supported with lock core 70, therefore can realize keeping being in locking and unlocking condition.In addition, when using key
When spoon rotates lock core 70, before two wall bodies 54 relative with screens breach offset, the second end is done in screens breach at the second end
Oscillating motion, dead bolt 60 is kept in locking and unlocking condition, until when the second end offsets with two wall bodies 54, sliding part 50 is subject to
Power-assisted does sliding motion, and now dead bolt 60 just starts toward opposite direction motion.
Specifically, for ease of effectively rotating lock core 70, the lock core 70 of the present embodiment is provided with square hole.
Preferably, described square hole axially runs through the lock core 70, and square hole is used to insert corresponding key, square hole and key
Spoon is coordinated with rotating coaxially mode is unlocked and is locked.
For ease of dismounting and positioning, the present embodiment lock core 70 is set to stepped.
Preferably, in order that revolving part 30 effectively can be realized rotating coaxially with lock core 70, the middle part of the revolving part 30
Square location hole is provided with, location hole is removably sheathed on lock core 70, under external force driving, lock core 70 and revolving part 30
Rotate coaxially.Explanation is needed exist for, the profile of the lock core 70 is set to stepped, and the two ends of the lock core 70 are and housing
40 with the cylindric of rotating manner installation, and pars intermedia is removably to be arranged cooperation with the location hole of the revolving part 30
Cube.
Preferably, in order that the second end can be fully with screens breach two wall bodies 54 offset, the sliding part 50 is remote
Gathering sill 53 is provided with from one end of through hole, gathering sill 53 slidably coordinates with lock core 70, under the effect of flexible member 20,
The two ends of gathering sill 53 have remained that one end is supported with lock core 70, and are able to ensure that the second end offsets with two wall bodies 54 completely,
Dead bolt 60 is set to be entirely retracted in lock and stretch out to reach the purpose effectively locked and unlock.Explanation is needed exist for, by institute
State gathering sill 53 often to slide, when the gathering sill 53 coordinates with the lock core 70, intermediate demand configures a packing ring, for protecting
The surface that shield lock core 70 is contacted with gathering sill 53 is not abraded by gathering sill 53, when the gathering sill 53 is slided, the gathering sill 53
With the washer contacts, friction produced when gathering sill 53 is slided can be reduced abrasion is caused to lock core 70, so as to reduce lock core
70 replacement frequency.
Preferably, renewal part for convenience, the flexible member 20 is configured as torsion spring, and one end of the torsion spring is with removable
The mode of unloading is sheathed on the extension rod 31.
Preferably, in order that the torsion spring produces elastic stress, the housing 40 to be provided with pillar 10, the torsion spring other end
Pillar 10 is sheathed in a rotatable manner.Specifically, revolving part 30 is rotated coaxially under the rotation of key with lock core 70, due to turning round
The spring other end is sheathed on pillar 10, and now torsion spring set is rotated located at one end of extension rod 31 with revolving part 30 and curved track is put
Dynamic, the distance at torsion spring two ends can be varied from when revolving part 30 is rotated, the steering regardless of revolving part 30, the torsion spring
Two ends distance all can be according to torsion spring set located at the one end of extension rod 31 movement locus change and by first shortening the side of elongation afterwards
Formula changes, and during the two ends Distance Shortened of torsion spring, torsion spring receives pressure in compressive state, when the distance at the two ends extends,
Torsion spring discharges pressure, and the pressure for being discharged is that torsion spring is used to order about the bullet that the second end offsets with two wall bodies 54 to the offer of revolving part 30
Property stress.
Preferably, the housing 40 is provided with mounting hole, and lock core 70 coordinates with mounting hole in a rotatable manner, and the mounting hole is used
In restriction lock core 70 free degree slidable in the axial direction.Why mounting hole described in the present embodiment can constrain lock core 70 vertically
The free degree that direction is slided because the lock core 70 is for stepped, therefore the columned two ends of lock core 70 and the mounting hole with
When rotary way coordinates, while free degree Constrained of the mounting hole to the axial direction of lock core 70.
The dead bolt 60 of the present embodiment needs to remain to be in locks and unlocking condition, therefore part 30 is rotated in key
Afterwards, the revolving part 30 needs to position and is locked and unlocking condition with realizing that dead bolt 60 keeps being in the sliding part 50.
Preferably, the screens breach is opened in top edge of the sliding part 50 away from pillar 10, screens breach it is relative
Two wall bodies 54 be provided with the first screens 51 and the second screens 52 being respectively clamped into for the second end.
As shown in Figure 1, it is preferred that first screens 51, near the wall body 54 of through hole, works as rotation lock located at screens breach
During core 70, flexible member 20 produces elastic stress to order about the second end and snaps in the first screens 51, and now gathering sill 53 is ordered about at the second end
One end and lock core 70 away from through hole are supported, so as to drive dead bolt 60 effectively to stretch out and dead bolt 60 is kept in locking state.
As shown in Figure 2, it is preferred that second screens 52, away from the wall body 54 of through hole, works as rotation lock located at screens breach
During core 70, flexible member 20 produces elastic stress to order about the second end and snaps in the second screens 52, and now gathering sill 53 is ordered about at the second end
Supported with lock core 70 near one end of through hole, so as to drive the effective retraction of dead bolt 60 to lock interior and dead bolt 60 is kept in unlocking shape
State.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim
Within the scope of.
