Abstract
The utility model relates to a clutch for lock, which includes a drive sheet 8, a coupling sheet 7, and a driven sheet 9 as well as an electric machine 3. The drive sheet 8 is fixed and connected with a handle 6; while the driven sheet 9 is connected with a shaft 10; the coupling sheet 7 is blocked in a clearance 11 between the drive sheet 8 and the driven sheet 9 and frictionally connected with the two sheets. The coupling sheet 7 is also connected with the electric machine 3 and driven by the latter to block into or leave the clearance 11. Through the positive or opposite rotation of the electric machine 3, the engaging or disengaging of the clutch is controlled, so as to make the lock work or out of service.
Description
The utility model relates to a kind of component of lock, particularly a kind of clutch of lock.
The purpose of this utility model provides a kind of clutch that is used for electronic lock, thus by motor positive and negative transfer solenoidoperated cluthes from realizing the work of lock with the state that closes and not working.
In order to reach the purpose of stating, the technical solution of the utility model is as follows:
A kind of clutch of lock comprises rotating plate 8, interlock sheet 7, driven disc 9, motor 3; Handle 6 is fixedlyed connected with rotating plate 8; Driven disc 9 is connected with axle 10; Interlock sheet 7 is installed in the space 11 between rotating plate 8 and the driven disc 9 and is connected with rotating plate 8 and driven disc 9 frictions respectively; Interlock sheet 7 is connected with motor 3, and motor 3 drives interlock sheets 7 and moves, and makes the sheet 7 that links snap in the space 11 or leaves space 11.
In preferred version of the present utility model, clutch also comprises slide block 5, spring 1, worm gear 2 and worm screw 4; Motor 3 is connected with interlock sheet 7 by slide block 5, spring 1, worm gear 2, worm screw 4; Worm screw 4 is contained on the axle of motor 3; Worm gear 2 and worm screw 4 engagements; Spring 1 is installed on the worm gear 2; Spring 1 is connected with slide block 5; Slide block 5 is connected with interlock sheet 7.
Slide block 5 is provided with a duck eye 12; Spring 1 on the worm gear 2 is corresponding to the position of duck eye 12, and two end pin of spring 1 are inserted in the duck eye 12.
Handle 6 and rotating plate 8 are connected by screw.
Owing to adopt above-mentioned structure, thus by motor positive and negative transfer solenoidoperated cluthes from realizing the work of lock with the state that closes and not working.
Fig. 1 is the structural representation of clutch of the present utility model from state the time;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the structural representation of clutch of the present utility model when closing state;
Fig. 4 is the B-B sectional view of Fig. 3.
Below in conjunction with accompanying drawing and example the utility model is described in further detail:
A kind of clutch of lock comprises rotating plate 8, interlock sheet 7, driven disc 9, spring 1, slide block 5, worm gear 2, worm screw 4, motor 3; Handle 6 and rotating plate 8 are connected by screw; Driven disc 9 is connected with axle 10; Interlock sheet 7 is installed in the space 11 between rotating plate 8 and the driven disc 9 and is connected with rotating plate 8 and driven disc 9 frictions respectively;
Worm screw 4 is contained on the axle of motor 3; Worm gear 2 and worm screw 4 engagements; Spring 1 is installed on the worm gear 2; Slide block 5 is provided with a duck eye 12; Spring 1 on the worm gear 2 is corresponding to the position of duck eye 12, and two end pin of spring 1 are inserted in the duck eye 12.
As shown in Figure 1, when motor 3 was rotated in the forward, motor 3 drove worm screw 4 and rotates, and worm screw 4 drives the rotation of worm gear 2 clockwise directions, moved upward by spring 1 drive slide block 5 and interlock sheet 7.Interlock sheet 7 is extracted out from space 11.At this moment, rotating plate 8 is in released state with driven disc 9, and promptly handle 6 is in released state with axle 10, even swing handle 6 also can't be opened lock.
As shown in Figure 2, when motor 3 reverse rotations, motor 3 drive worm screws 4 are rotated, and worm screw 4 drives worm gears 2 rotation counterclockwise, moves downward by spring 1 drive slide block 5 and interlock sheet 7, and interlock sheet 7 inserts in the spaces 11.At this moment, rotating plate 8 is in engagement state with driven disc 9, and promptly handle 6 is in engagement state with axle 10, and swing handle 6 just can be opened lock.
In such scheme, spring 1 also has position-limiting action, limits worm gear 2 and rotates in working range.
