Description

Finger lock

The utility model relates to a kind of lockset.

The lockset that is used for the locking door at present is of a great variety, structure is different, and the existing cylinder lock that opens the lock with the key also have not make the coded lock that opens the lock with the key, and the encoded keyboard of existing coded lock all exposes outside lock housing, and unlocking cipher is digital combination.Use the most general its anti-theft security of cylinder lock relatively poor, so how to install anti-theft safety door additional at the door place.

It is figure that the purpose of this utility model provides a kind of unlocking cipher, and the keyboard of unblanking is positioned at the Finger lock of lock shell cavity.

Finger lock by lock housing, be positioned at that lock housing connects and supporting be fixed on elastomeric bearing on the lock housing, be fastened on unlocking apparatus on the elastomeric bearing, be positioned at unlocking apparatus below and supporting be fixed on the lock housing by the post dish, be positioned at by post dish below with paste folded locking disk by the post dish, be positioned at the locking disk below and constitute with the dead bolt that locking disk pastes folded wheel ball bearing, expert's handle, outdoor handle and band pushing tow return spring, elastomeric bearing and constitute the storehouse of unblanking of lockset by lock shell cavity between the post dish, finger stretch into and utilize unlocking apparatus to push by post in the storehouse of unblanking can to open by lock.By be equipped with on the post dish take back a spring by post, arrange along card matrix form dislocation by post.Locking disk is loaded on the lock housing boss slideway and can comes and goes slippage along slideway, have on the card with by post pellet shot from a slingshot hole one to one, pellet shot from a slingshot is equipped with pellet shot from a slingshot in the hole.Disk body has the pushing tow return spring and the elastic bolster guide of band guide pillar, and the return spring guide pillar is connected along integral body with the locking disk hub disk, and elastic bolster guide is fastened on by post dish hub disk along last.Under the wheel ball bearing there be and the whole symmetrical knife edge guide rail that is connected of disk body card, on the guide-track groove of wheel ball bearing support, the wheel ball bearing support is fixed on the lock housing disk body by the knife edge guide rail support, and wheel ball bearing can come and go slippage along guide-track groove.The pellet shot from a slingshot of band pushing tow return spring is housed on the wheel ball bearing, and the wheel ball bearing pellet shot from a slingshot is corresponding one by one with the locking disk pellet shot from a slingshot.The wheel ball bearing pellet shot from a slingshot is made up of a coding pellet shot from a slingshot and an empty sign indicating number pellet shot from a slingshot, and the coding pellet shot from a slingshot partly plays post and stretches in locking disk pellet shot from a slingshot the hole in and contact with the locking disk pellet shot from a slingshot, and empty sign indicating number pellet shot from a slingshot and the locking disk pellet shot from a slingshot face of contacting are positioned at locking disk and the wheel ball bearing subsides are folded at the interface.The coding pellet shot from a slingshot is arranged into the projecting figure that unlocking apparatus is pressed key spare along card.There is the whole group push pedal that connects the forward and backward rim of wheel ball bearing, and hub disk is along the pushing tow return spring that the band guide pillar is arranged, and pushing tow return spring guide pillar is connected with disk body is whole.The contiguous shroud of card has the whole dead bolt latch that connects along centre under the wheel ball bearing.Dead bolt is loaded on the lock housing, has open-work, dead bolt latch draw-in groove and dead bolt latch chute on the dead bolt bar, and open-work one axial hole wall is a tooth plate shape wall surface of the hole, and dead bolt latch chute is communicated with dead bolt latch draw-in groove.The dead bolt latch cooperates with draw-in groove the dead bolt locking, and the dead bolt latch enters the scalable displacement of dead bolt in the chute.Push pedal and half gear are housed on the handle of innner and outer, and reverse backstop cooperates between the outer wheel face of half gear of innner and outer handle.Outdoor handle rotates, push pedal is dialled and pushed away that the dead bolt latch of dialling the slippage of push pedal wheel ball bearing, wheel ball bearing before the wheel ball bearing enters in the chute by withdrawing from the draw-in groove, outdoor handle half gear meshes with dead bolt open-work tooth plate, and dead bolt is outside under the handle drives in the retraction lock housing.Rotation expert handle, push pedal are dialled push pedal and locking disk elastic bolster guide after dialling and pushing away wheel ball bearing, and elastic bolster guide is removed the backstop to locking disk, locking disk slippage under wheel ball bearing drives.The dead bolt latch of wheel ball bearing withdraws from when entering chute outdoor handle half gear and expert's handle half gear simultaneously and the engagement of dead bolt open-work tooth plate by draw-in groove, and dead bolt is under expert's handle drives in the retraction lock housing.

Further improving of Finger lock is that lockset has lock to insert.Lock is inserted by the plate that is bearing on the lock housing and is constituted with the operating grip that gear is housed.Have open-work on the plate, open-work one axial hole wall is a tooth plate shape wall, the gear of operating grip and tooth plate engagement.Outdoor handle is equipped with the torsion return spring.

In order to adapt to different instructions for uses, a kind of structural shape of Finger lock unlocking apparatus, be to connect the finger locating that the turns left and right folder that support bar that the other end fixedlys connected with the jerk-finger hoop constitutes with elastomeric bearing by a jerk-finger hoop and an end, the jerk-finger hoop of finger locating folder refers to that by forefinger, middle finger, the third finger, little mother hoop constitutes.Utilize finger locating folder location to press...with one's finger and press and to lock the pellet shot from a slingshot of encoding when opening is arranged into finger along card projecting figure by post.

Second kind of structural shape of Finger lock unlocking apparatus is by the presser type unlocking apparatus that is fastened on the support that has slideway on the elastomeric bearing, is loaded on the slide block of screwing screw rod, be loaded on the support slideway and cooperate with screw flight on the support, has on the plate face that is fastened on the pressing plate that has finger ring on the slide block, the knob scale that is connected with screw rod one end integral body and is loaded on the scale place panel that screw rod is screwed beginning flag to constitute.Utilize the pressing plate of presser type opening device to push and to lock coding pellet shot from a slingshot when opening is arranged into pressing plate along card projecting figure by post.

Two kinds of unlocking apparatus can be installed and used separately also compound use can be installed simultaneously according to instructions for use.In order further to improve the confidentiality and the anti-theft security of Finger lock, door is equipped with at the Finger lock Hatch Opening place of unblanking, and the door of unblanking is locked sealed by the whole button-type mechanical password door that is connected of lock housing and Finger lock.

The Finger lock that the utility model the provides button of unblanking is hidden in the storehouse of unblanking of lock housing, and unlocking cipher is a figure, and the storehouse of unblanking is provided with door and uses sealedly with the whole key-type mechanical puzzle lock that is connected of Finger lock, so strong security, pick-proof, theftproof performance are reliable.Lockset can be made and can only also be can be made into and can will be locked many human locks of opening by many people by the special use lock of specifying the special messenger lock can be opened according to instructions for use.
