Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts The every other embodiment obtained, shall fall within the protection scope of the present invention.

In the lock body that existing key is opened, pass through rotating machinery key, you can enable the solution lockhole of unlock pulling block end sudden and violent Expose, pulling block can be unlocked with conventional tool rotating machinery key and achievees the purpose that open lock, from certain angle still There is the possibility that non-real user identity opens lock.

In order to solve the above-mentioned technical problem, Fig. 1 is referred to, the present embodiment provides one kind, and there is the when of opening the lock with the key to pass through electricity The lock body of magnetic clutch unlocking function.

The lock core 10 and electromagnetic clutch structure 20 that the lock body includes lock tongue 30, is rotated by key.Fig. 2-3 is referred to, Wherein, electromagnetic clutch structure 20 include be set to lock core 10 on unlock handsetting block base 40 and Electromagnetic Control and lockable unlock The drive component 50 of handsetting block base 40 and lock core 10；Handsetting block base 40 is unlocked to be sequentially connected with lock tongue 30.Drive component 50 can be to solution It realizes and locks or unlocks between lock handsetting block base 40 and lock core 10.When being locked between unlock handsetting block base 40 and lock core 10, pass through key Spoon rotary locking cylinder 10, lock core 10 can drive unlock handsetting block base 40 to rotate, and then complete to open to lock tongue 30；When unlock handsetting block base When unlocked between 40 and lock core 10, when key rotary locking cylinder 10, lock core 10 can dally, and the completion of lock tongue 30 can not be driven to open It opens.

In order to solve the technical problem for the possibility locked there are the non-personnel's opening for grasping unlocking information, in the present embodiment, Drive component 50 can be driven by magnetic card lock, coded lock, voiceprint lock, Fingerprint Lock, face recognition lock or the pupil lock being arranged on lock body It is dynamic, it can ensure that the talent for grasping unlocking information can complete to unlock, and improve the security performance of lock body using the above structure.

It elaborates below to the lock body by electromagnetic clutch unlocking function：

Refer to Fig. 3-5, wherein lock core 10 is cylinder, and handsetting block base 40 is rotatable is sheathed on outside lock core 10 for unlock.It is locking Several notches 11 are along the circumferential direction formed on the lateral wall of core 10, being right against notch 11 on unlock handsetting block base 40 is formed with Clutch pushes away column 41, which pushes away column 41 and can be moved towards notch 11, so be entrenched in notch 11 or with 11 clutch of notch.Due to Clutch pushes away the setting of column 41 on unlock handsetting block base 40, clutch push away column 41 be entrenched in notch 11 or with 11 clutch of notch, you can it is real Now unlock locking or unlocking between handsetting block base 40 and lock core 10.

In order to ensure unlock handsetting block base 40 and lock core 10 are for clutch state, clutch pushes away column 41 and passes through unlock handsetting block base 40 On elastic construction 42 be resisted against the lateral wall of lock core 10, and elastic construction 42 enables clutch push away column 41 far from lock core 10, you can makes It must unlock and be in clutch state between handsetting block base 40 and lock core 10 always.Wherein, elastic construction 42 can be spring or other tools Component flexible and with the same function.

Fig. 3 is referred to, in addition, the drive component 50 of electromagnetic clutch structure 20 includes pedestal 51 and is fixed on pedestal 51 And with electromagnetism push pin 52 electromagnet 53.Electromagnetism, which is pushed pin, 52 is resisted against the end that clutch pushes away column 41, for pushing clutch to push away Column 41 is moved towards notch 11.After clutch pushes away the insertion notch 11 of column 41, the locking between unlock handsetting block base 40 and lock core 10 is completed. In this configuration, the electromagnet 53 of drive component 50 passes through the magnetic card lock, coded lock, voiceprint lock, Fingerprint Lock, the face that are arranged on lock body Portion's identification lock or pupil lock driving.

Since pedestal 51 is integrally fixed in lock body, and lock core 10 can then be rotated with key, therefore during unlocking, electricity Magnetic push pin 52 and the position that pushes away between column 41 of clutch will produce relative movement, in order to ensure unlock handsetting block base 40 is in lock core 10 Lock-out state, electromagnetism push pin 52 should be pushed away with clutch column 41 always be in contact condition.To sum up, the present embodiment electromagnetism push pin 52 with Clutch is formed with guide stop block 62 between pushing away column 41.Specifically, being formed with column 61 on pedestal 51, opened on guide stop block 62 If 61 clearance fit of Kong Weiyu columns, enable guide stop block 62 is rotatable to be sheathed on column 61.Electromagnetism, which is pushed pin, 52 to be resisted against and leads To the one side of block 62, guide stop block 62 is pushed to rotate；The another side of guide stop block 62 is resisted against clutch and pushes away column 41 always, It rotates and clutch is pushed to push away column 41 and moved towards notch 11.

In order to improve smoothness when key unlocking, the side for pushing away column 41 on guide stop block 62 towards clutch is in arc surface, Clutch pushes away end and the arc surface CONTACT WITH FRICTION of column 41.And it is in ball that clutch, which pushes away the end face contacted with guide stop block 62 on column 41, Shape.Can also push pin simultaneously towards electromagnetism on guide stop block 62 52 side on be formed with and contacted with push pin 52 end of electromagnetism Against block.

Lock body unlocking process provided in this embodiment is as follows：Fig. 6 is referred to, in the state that lock body has been locked, lock core 10 It is free between unlock pulling block seat, external force (such as key or picklock) band movable lock core 10 is in unlock pulling block seat overhead Turn.Fig. 7 is referred to, when unlocking to lock body, needs to input a correct unlocking information to door lock, such as password, refer to Line etc., after door-locking system receives correct information, allow drive component 50 work, electromagnetism push pin 52 promotion guide stop blocks 62 rotation one The rotation forces clutch of fixed angle, guide stop block 62 pushes away the movement of column 41, and then lock core 10 and unlock pulling block seat is sealed at one Body, key rotation lock core 10, unlock handsetting block base 40 can drive lock tongue 30 to complete unlocking action by associated mechanisms at this time.

Drive component provided in this embodiment can realize driving by grasping the personnel of unlocking information, and then solve use Key unlocking improves the safety coefficient of lock body there are the technical problem that the non-personnel for grasping unlocking information open the possibility locked.

Embodiments described above does not constitute the restriction to the technical solution protection domain.It is any in above-mentioned implementation Modifications, equivalent substitutions and improvements etc., should be included in the protection model of the technical solution made by within the spirit and principle of mode Within enclosing.
