Abstract

The utility model relates to a lock core with an electric control clutch, which is provided with a lock core base block; the lock core base block is internally provided with the electric control clutch and a shifting fork; and the electric control clutch consists of an electromagnetic pin arranged in a lock bulb through cavity of the base block and a lock bulb shaft. The outline of the lock core is same as that of a mechanical lock core and can replace the mechanical lock core; the electric control clutch in the lock core is controlled by an electronic device; when the clutch is separated, the lock bulb shaft and the shifting fork are separated, a handle knob only can drive the lock bulb shaft to rotate in idle and can not realize unlocking or locking; and when the clutch is connected, the lock bulb shaft can drive the shifting fork to rotate, the shifting fork shifts a lock tongue to act so as to realize unlocking or locking. The lock core can use an electric control mode to control the mechanical lock core to act, can become an actuating mechanism for unlocking and locking an electronic lock directly and provide convenience for upgrading a mechanical lock into the electronic lock.

Description

The lock core of charged control clutch

Technical field

The utility model relates to a kind of electronic lock, and specifically, it is a kind of lock core of charged control clutch.

Background technology

At present, existing security door all adopts mechanical lock mostly, and the disadvantage of mechanical lock is that keyhole is arranged, and this is just disclosed and pried open by master key easily, is also filled in foreign matter by the people easily, causes and can't use.Electronic lock can overcome the above-mentioned shortcoming of mechanical lock, and it does not establish keyhole, adopts automatically controlled mode directly to drive dead bolt.But when changing mechanical lock with electronic lock, both structures are difficult to reach the degree of exchange, and the lockhole of special mechanical lock can't remedy, and the profile of electronic lock also is difficult to and the cooperating of mechanical lock.So it is still very very difficult to want that mechanical lock is replaced with electronic lock.

The utility model content

The purpose of this utility model is in order to solve the problem in the prior art, a kind of lock core of charged control clutch to be provided, making mechanical lock escalate into electronic lock and become easy.

To achieve these goals, the technical solution of the utility model is as follows:

It has a lock core matrix, the upper axial of this lock core matrix is provided with a cylindrical lock gall cavity, its improvements are: be provided with a cross-section groove at the middle part of this lock gall cavity, before this cross-section groove is divided into described lock gall cavity, latter two cavity, in this cross-section groove, be provided with a shift fork, preceding, an electric control clutch is housed in latter two cavity, lock gall axle in the cavity constitutes this electric control clutch by the electromagnetism pin in the cavity before being contained in after being contained in, afterbody at preceding cavity also is equipped with a hollow connector, the front end of described hollow connector and lock gall axle is equipped with the spindle nose that stretches in the cross-section groove, described shift fork is installed on these two spindle noses, the pin rod of described electromagnetism pin inserts in the shift fork with rectangle hole loose fit structure, front end face at lock gall axle spindle nose is provided with the cotter way that matches with the pin rod of electromagnetism pin, connects firmly a handle knob at the tail end of lock gall axle.

The further improved technical scheme of the utility model is as follows:

Described electromagnetism pin by electromagnetic coil, be located at iron core in the electromagnetic coil, connect firmly at the pin rod of iron core front end and the back-moving spring that is contained in the iron core afterbody and constitute.

By technique scheme as can be seen, the utility model is the lock core of a charged control clutch, and its profile is identical with mechanical lock, can replace mechanical lock with it, electric control clutch is controlled by electrical lock apparatus in the lock core, and during clutch separation, the lock gall axle separates with shift fork, the handle knob can only drive the idle running of lock gall axle, can not unblank or locking, when clutch closed, the lock gall axle can drive shift fork and rotate, shift fork is stirred the dead bolt action, realizes unblanking or locking.The utility model electricity consumption prosecutor formula has replaced the function of mechanical lock, and it can directly become the executing agency of unblanking of electronic lock and locking, provides convenience for mechanical lock upgrades to electronic lock.

The A-A cross-sectional view of Fig. 2, Fig. 1.

The specific embodiment

Referring to Fig. 1, it has a lock core matrix 1, upper axial at this lock core matrix is provided with a cylindrical lock gall cavity, be provided with a cross-section groove at the middle part of this lock gall cavity, before this cross-section groove is separated into described lock gall cavity, latter two cavity 1-1,1-2, in this cross-section groove, be provided with a shift fork 2, preceding, an electric control clutch is housed in latter two cavity, lock gall axle 3 in the cavity constitutes this electric control clutch by the electromagnetism pin in the cavity before being contained in after being contained in, described electromagnetism pin is by electromagnetic coil 4-1, be located at iron core 4-2 in the electromagnetic coil, the pin rod 4-3 that is threaded in the iron core front end constitutes with the back-moving spring 4-4 that is contained in the iron core afterbody, for shift fork 2 is installed, afterbody in preceding cavity 1-1 is equipped with a hollow connector 5, and the front end of this hollow connector and lock gall axle is equipped with the spindle nose 5-1 that stretches in the cross-section groove, 3-1, described shift fork 2 is installed on these two spindle noses, and can rotate around this spindle nose, front end at preceding cavity 1-1 also is provided with an end cap 6, and it compresses the location with electromagnetic coil and hollow connector.For pin rod can be endwisely slipped, can drive shift fork again rotates, referring to Fig. 2, the cross section of the front portion of described pin rod 4-3 is rectangle, and loose fit is inserted in the oblong aperture of shift fork 2, spindle nose end face at lock gall axle 3 is provided with the cotter way 3-2 that cooperates with pin rod 4-3, connects firmly a handle knob 7 at the tail end of lock gall axle 3.

Operating principle is: when in the electromagnetism pin during electromagnetic coil 4-1 dead electricity, iron core is positioned at the position of retraction, i.e. state shown in Fig. 1 with pin rod 4-3 under the effect of back-moving spring 4-4, make clutch be in released state, at this moment, rotary handle knob 7, the lock gall axle dallies and can not drive the shift fork rotation; When electronic installation (as the electronics decoder) is powered for the electromagnetism pin, electromagnetic coil 4-1 gets electric and produces electromagnetic force, make iron core 4-2 band pin rod 4-3 reach (moving) to drawing the right, then the front end of pin rod 4-3 stretches into cotter way 3-2, and clutch closes, at this moment, rotary handle knob 7, the lock gall axle drives pin rod 4-3, and pin rod drives shift fork and rotates, and is stirred by shift fork that dead bolt is unblanked or locking.
