By means of the disengaging and engaging mechanism, it can be ensured that electronic unlocking and mechanical unlocking are achieved at the same time, and the disengaging and engaging mechanism is easy to operate, convenient to use and practical when dealing with machine emergency.

Description

A kind of clutch for intelligent fingerprint lock

Technical field

The present invention relates to electronic lock field, specifically refer to a kind of clutch for intelligent fingerprint lock.

Background technology

Present safety lock body, is divided into full mechanical anti-theft lock lock body and electronic intelligence safety lock body. Full mechanical anti-theft lock, because of the inconvenient life characteristic that is more and more not suitable with modern of locking a door, is progressively replaced by electronic safety lock; But, original electronic lock body, general thickness is thick, wider width, and volume is larger, can not meet the installation requirement of some antitheft doors (particularly thin door), and the damage of opposite house is larger simultaneously; And existing electronic lock rotarily opens in the control of door lock 360 ° of processing handles, and structure is too complicated, and the way not had on processing machine key is emergent.

Summary of the invention

The object of the present invention is to provide a kind of clutch for intelligent fingerprint lock, in the situation that not changing original lock body and aperture of door, conveniently realize mechanical door lock and become the replacement of electronic lock.

Object of the present invention is achieved through the following technical solutions:

A kind of clutch for intelligent fingerprint lock, comprise circular box body, multiple pins and be fixed on the core that turns at box body middle part, the described core middle part that turns has the through hole passing for handle rotating shaft, on two sidewalls of described pin one end, have rectangular channel, multiple back-up blocks that mate with pin are installed in the circle wall of described box body, described back-up block middle part has aperture, the pin other end runs through aperture and is placed in box body, and on aperture inwall, being provided with flange and described flange inner wall contacts with rectangular channel bottom land, on the described outer wall that turns core, have multiple spacing holes coaxial with pin, also comprise the spring being arranged in rectangular channel, and the end of described spring is fixed on the upper surface of described flange, described spacing hole inwall comprises the adjustment section, changeover portion and the flat segments that connect successively, the described section internal diameter of adjusting successively decreases along the radially ecto-entad that turns core, described flat segments is the column disc isometrical with pin, and described changeover portion is along the outstanding smooth surface of described pin axis. in the time that electronic lock cannot be realized electronics and unblanks and adopt mechanical key to meet an urgent need, in the case of the normal machinery of mechanical key is opened, make pin radially do rectilinear motion towards its center of circle along box body, the end that is pin directly coordinates with spacing hole, box body is rotated together with turning core, the handle of electronic lock body rotates thereupon, simultaneously in the rotation process of handle, multiple pins are movable setting, box body with turn core synchronize rotate process in, multiple pins coordinate with its corresponding spacing hole successively, and the pin completing after cooperation is again returned to initial position under the elastic recovery active force of spring, reciprocal with this, until lock is opened completely. and in the time using electronics to unblank, and while closing the door state, lock core is in empty rotation status, handle cannot opening door lock, the instruction of arriving the driving mechanism of electronic lock body need to open the door time by electronic signal transmission, now multiple pins and spacing hole, realization becomes the Coupled motion of a transmission with box body and handle, realization is opened the door, and handle is in the process of rotation, and multiple pins are rotated, realize continual work, until complete the action of opening the door. therefore, the present invention can ensure to realize electronics simultaneously and unblank to unblank with machinery, and in the time that processing machine is emergent, simple to operate, convenient and practical.

Wherein, in the time that coordinating with spacing hole, pin easily there is the upper surface dislocation of pin end and spacing hole, make pin be obstructed to the movement of spacing hole, and spacing hole comprises adjustment section in the present invention, changeover portion and flat segments, internal diameter and the pin of flat segments are isometrical, in the folding process of pin, its end first contacts with the adjustment section of spacing hole, the upper end diameter of adjusting section is greater than the external diameter of pin, pin can enter into fast and adjust section, along with turning the movement of core, pin end face enters into flat segments after slipping over smooth fillet surface smoothly, realize the quick centring of pin and spacing hole, ensure that the quick drive of pin turns core and moved to unblank.

The internal diameter of described spacing hole is greater than the external diameter of described pin. before pin coordinates with spacing hole, box body is two independent individualities with turning core, after pin coordinates with spacing hole, multiple pins drive corresponding spacing hole and turn core and rotate together, and then realize the object of unblanking, and in the time that pin drive turns core motion, the aperture of spacing hole is greater than the external diameter of pin, make pin can carry out in advance moving freely of a segment distance in spacing hole, until pin outer wall contacts with spacing hole inwall, utilize the motional inertia of pin to drive fast to turn core and move, avoid pin under original state, directly to drive the live load that turns core and increase driving mechanism, reduce difficulty when electronics is unblanked or machinery is unblanked.

The number of described pin is 6. As preferably, the number of pin is set to 6, and is evenly distributed in the circle wall of box body, in the time turning core rotation, pin and spacing hole contact and stressed more even, increase the stability of door lock in the time opening or close, reduce to turn the wearing and tearing between core and box body simultaneously.

The present invention compared with prior art, has following advantage and beneficial effect:

1, the present invention can ensure to realize that electronics is unblanked and machinery is unblanked simultaneously, and in the time that processing machine is emergent, simple to operate, convenient and practical;

2, the present invention utilizes the motional inertia of pin to drive fast to turn core and moves, and avoids pin under original state, directly to drive the live load that turns core and increase driving mechanism, reduces difficulty when electronics is unblanked or machinery is unblanked;

3, the number of the present invention's pin is set to 6, and be evenly distributed in the circle wall of box body, in the time turning core and rotate, pin and spacing hole contact and stressed more even, increase the stability of door lock in the time opening or close, reduce to turn the wearing and tearing between core and box body simultaneously.
