Abstract

The utility model relates to a clutch means of a lock, which comprises a front clutch plate 12 and a rear clutch plate 11, wherein the rear clutch plate 11 is separated from the front clutch plate 12 and a clearance 13 is arranged between the rear clutch plate 11 and the front clutch plate 12. The clutch means of a lock also comprises a driving wheel 4, a driving lever 5, a sliding bar 7, a sliding block 10, an electronic driving mechanism, and a mechanical driving mechanism, wherein the driving lever 5 forms the shape of an arc and can only rotate around a fixed point 6; the sliding bar 7 which is also arc-shaped and is sheathed with one end of the driving lever 5 can also only rotate around the fixed point 6; the sliding block 10 is sheathed on the sliding bar 7 at the position corresponding to the clearance 13; the electronic driving mechanism is engaged with the driving lever 5 through the driving wheel 4; the mechanical driving mechanism is connected with the sliding block 10. The utility model controls the engaging and disengaging state of the clutch means through the clockwise and anticlockwise of a motor or through the rotation of a mechanical key, and consequently realizes the working and non-working state of the lock.

Description

The arrangement of clutch of lock

Technical field

The utility model relates to a kind of component of lock, particularly a kind of arrangement of clutch of lock.

Background technology

At present, the arrangement of clutch of the employed lock of people is varied.

Summary of the invention

The purpose of this utility model provides a kind of arrangement of clutch that is used for electronic lock, the separating and combine of the ingenious cooperation control clutch device by electronic mechanism and mechanical mechanism, realizes the work of lock and does not work.

In order to achieve the above object, the technical solution of the utility model is as follows:

A kind of arrangement of clutch of lock, clutch-plate 12 and back clutch-plate 11 before comprising; Back clutch-plate 11 separates with preceding clutch-plate 12, between leave space 13; The arrangement of clutch of lock also comprises thumb wheel 4, driving lever 5, slide bar 7, slide block 10, electronic driving mechanism and mechanical driving mechanism; Driving lever 5 cambers also can only rotate around fixed point 6; Slide bar 7 also camber and with driving lever 5 one end sockets, also can only rotate around fixed point 6; Slide block 10 is sleeved on the slide bar 7, and the position is corresponding to space 13; Electronic driving mechanism is by thumb wheel 4 and driving lever 5 bridle joints; Mechanical driving mechanism and slide block 10 join.

In preferred version of the present utility model, electronic driving mechanism comprises motor 1, worm screw 2 and worm gear 3; Worm screw 2 is contained on the axle of motor 1, worm screw 2 and worm gear 3 engagements, and thumb wheel 4 is contained on the worm gear 3 and is coaxial.

Mechanical driving mechanism comprises tapered end clutch-plate 8 and key rotating disk 9; Tapered end clutch-plate 8 is located at the below of slide block 10; Key rotating disk 9 is contained in the square groove 14 of tapered end clutch-plate 8.

Owing to adopted said structure, thus the rotation of rotating by motor or mechanical key come solenoidoperated cluthes from realizing the work of lock with the state that closes and not working.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

A kind of arrangement of clutch of lock, clutch-plate 12 and back clutch-plate 11 before comprising; Back clutch-plate 11 separates with preceding clutch-plate 12, between leave space 13; The arrangement of clutch of lock also comprises thumb wheel 4, driving lever 5, slide bar 7, slide block 10, electronic driving mechanism and mechanical driving mechanism; Driving lever 5 cambers also can only rotate around fixed point 6; Slide bar 7 also camber and with driving lever 5 one end sockets, also can only be admittedly rotate around fixed point 6; Slide block 10 is sleeved on the slide bar 7, and the position is corresponding to space 13; Electronic driving mechanism is by thumb wheel 4 and driving lever 5 bridle joints; Mechanical driving mechanism and slide block 10 join.

Electronic driving mechanism comprises motor 1, worm screw 2 and worm gear 3; Worm screw 2 is contained on the axle of motor 1, worm screw 2 and worm gear 3 engagements, and thumb wheel 4 is contained on the worm gear 3 and is coaxial.

Electronic driving mechanism is connected to form elasticity by thumb wheel 4 with driving lever 5 and is connected, and does not hinder mechanical driving mechanism driving sliding block 10 to move up and down.

As shown in Figure 1, when motor 1 was rotated in the forward, motor 1 drive worm screw 2 was rotated, and worm screw 2 drives worm gears 3 rotation counterclockwise, reaches upwards swing of slide bar 7 to the right by thumb wheel 4 drive driving levers 5, and slide block 10 inserts in the space 13 of back clutch-plates 11 and preceding clutch-plate 12.At this moment, back clutch-plate 11 joins by slide block 10 with preceding clutch-plate 12, is in engagement state, and clutch-plate 12 rotates before driving, and can unblank, as shown in Figure 2 state.

As shown in Figure 2, when motor 1 reverse rotation, motor 1 drives worm screw 2 and rotates, when worm screw 2 drives the rotation of worm gear 3 clockwise directions, drive driving lever 5 by thumb wheel 4 and reach slide bar 7 left to lower swing, slide block 10 is extracted out from the space 13 of back clutch-plate 11 and preceding clutch-plate 12.At this moment, back clutch-plate 11 separates with preceding clutch-plate 12, and clutch-plate 12 rotates before can't driving, and can not unblank, as shown in Figure 1 state.

As shown in Figure 3, below slide block 10, also be provided with tapered end clutch-plate 8, rotation by mechanical key drives 9 rotations of key rotating disk, key rotating disk 9 further drives tapered end clutch-plate 8 motion up or down, the space 13 of back clutch-plate 11 and preceding clutch-plate 12 is extracted and inserted to control slide block 10 out, also can realize the work of locking and do not work.
