Description

A kind of arrangement of clutch of electronic lock
Technical field:
The invention belongs to the lock technology field of fixed buildings portion in the International Patent Classification (IPC), more particularly, relate to a kind of improvement of electronic lock arrangement of clutch structure.
Background technology:
At present, the door lock of selling on the market roughly can be divided into two kinds, i.e. mechanical lock and electronic lock.So-called mechanical lock is meant and is mechanical connection between each parts in the whole lock body that this type door lock is widely used in life; Wherein, the common structure of the unlocking apparatus of mechanical lock is the shifting block that comprises between interior plectrum, outer plectrum and the inside and outside plectrum; Though mechanical lock does not need energising, the shortcoming of its existence is a poor stability, shows that mainly the key of opening mechanical lock is easy to duplicate, yet is used for difficult the copying of electron key of unlocking electronic lock.
And so-called electronic lock is meant that the unlocking mechanism in the lock body passes through electric power control, can be divided into motor type electronic lock and electromagnetic type electronic lock again.The common structure of motor type electronic lock unlocking apparatus is: motor driven gear rotates, and promotes telescopic mast and gets into or leave arrangement of clutch, gets into arrangement of clutch through telescopic mast and realizes that outer handle unblanks, and internal construction is complicacy comparatively; And if telescopic mast does not cut off the power supply when resetting, arrangement of clutch lost efficacy, the outer handle of door lock all can be unblanked having or not under the situation of mandate.In addition, the mode of unblanking of more existing electromagnetic type electronic locks is because unlocking mechanism directly acts on dead bolt, and drive current is excessive, and arrangement of clutch in the middle of lacking, so performance difficulty.
Summary of the invention:
The present invention is exactly to the problems referred to above, overcomes the deficiency that prior art exists, and a kind of arrangement of clutch of electronic lock is provided; Electronic lock with this arrangement of clutch is not only simple in structure, safe and reliable, and to a large amount of mechanical locks that use in the life, utilizes this arrangement of clutch to be easy to be transformed into the electromagnetic type electronic lock.
For realizing above-mentioned purpose of the present invention; The present invention adopts following technical scheme; The dead bolt connecting rod that the present invention includes lock body, dead bolt, is connected with the dead bolt axle, and with dead bolt link to each other from locking plate mechanism, from locking plate mechanism by last from locking plate, side from locking plate with form from locking plate down; Its structural feature is that described lock body top is provided with electromagnet, be disposed with on the interior handle hole of electromagnet below interior plectrum, interior shifting block, can be on interior shifting block in relative rotation outside shifting block, outer plectrum; The middle part of described interior shifting block has can make interior shifting block be fixed on the interior dial hole on the interior handle; Set gradually on the side of interior shifting block and be useful on an interior rib of stirring the dead bolt connecting rod counterclockwise, be used for stirring clockwise the dead bolt connecting rod in triangular; And be used for stirring clockwise interior two ribs from locking plate; In interior shifting block between a rib and interior two ribs be provided with and have the clutch block that rotating shaft, end have the clutch gap; Clutch block has the end adhesive mutually of magnetic patch with plectrum on the axle, and the other end of plectrum joins with electromagnet; The middle part of described outer shifting block has can make outer shifting block be fixed on the outer dial hole on the outer handle; Set gradually on the side of outer shifting block and be useful on an outer rib of stirring the dead bolt connecting rod counterclockwise, can be stuck in outer four ribs on the dead bolt connecting rod when being used to clockwise rotate, and when clockwise rotating can with the clutch gap of said clutch block outer two ribs of interlock mutually.
Adopt the unlocking mechanism of the arrangement of clutch of said structure, the motor type electronic lock structure that contains motor, gear is simple; And compare with mechanical lock, safe; In addition, arrangement of clutch of the present invention is simple in structure, and the electronic lock body internal construction is very similar with the existing mechanical lock, so be easy to transform.
As a kind of improvement of the present invention, can be provided with pin by interior group of opening position in the clutch block bottom, between an interior rib and interior two ribs, be provided with the bayonet socket that can stop pin to rotate counterclockwise corresponding to the interior plectrum of pin.After adopting this kind structure; Clutch block and outer two ribs outside handle unblank under the improper situation of continued interlock; Be that clutch block does not reset; Because interior handle is when locking a door, the pin of the outer shifting block clutch block that rotates counterclockwise can make its pressures separate with outer two ribs through bayonet socket, make do not have mandate can from outside situation that lock is opened can not take place.
As another kind of improvement the of the present invention, when being provided for rotating counterclockwise on the outer shifting block side between two ribs and outer four ribs outside with outer two ribs, the clutch block of interlock mutually push aside outer triangular; Automatically separate under the normal condition of outer two ribs of clutch block and outer shifting block after handle is unblanked outside; But take place when outer two ribs and clutch block continue the abnormal conditions that interlock, clutch block do not reset, outer triangularly can force to push aside clutch block because outer handle when locking a door, rotates counterclockwise, make the nothing mandate can from outside situation that lock is opened can not take place.
As another kind of improvement the of the present invention, can interior shifting block and outside brace is set between the shifting block; Because interior shifting block, outer shifting block all can relatively rotate on brace, even utilize drill bit to be difficult to destroy by force arrangement of clutch like this.
