Abstract
The utility model provides the transmission device of a kind of lock gall band dynamic clutch work, the structure of this transmission device is by mandrel and translation shaft transmission at lock gall, translation shaft to be placed in translation axle sleeve and to coordinate with translation shaft external threading, when lock gall rotates, translation shaft can be driven to extrude or away from lock gall shifting block, realize the work of lock gall band dynamic clutch.The utility model is by simple drive mechanism, and application threaded rod promotes principle, enhances transmission effect, without the need to applying larger power; Have that structure is simple, thrust is large, better, the nonabradable advantage of feel.
Description
Technical field
The utility model relates to a kind of transmission device of lock clutch, is specifically related to the transmission device that a kind of lock gall drives the external clutch work of lock body.
Background technology
The clutch majority of current electronic lock be by the positive and negative rotation of micro machine with dynamic clutch from the state of conjunction, when electronic control system is malfunctioning, the mechanical transmission structure between lock gall and clutch can also be utilized, by the positive and negative rotation of people's hand control lock gall realize clutch from conjunction state.There are these problems following in the transmission device between the lock gall of current most electronic lock and clutch: adopts this to take turns the structure of transmission or other more complicated; Moment of torsion between lock gall and clutch is comparatively large, rotates when lock gall promotes clutch and need compare effort; The position that driving parts is worked in coordination easily produces wearing and tearing and contraposition is inaccurate, causes transmission failure.
Summary of the invention
The utility model provides the transmission device of a kind of lock gall band dynamic clutch work, solving lock gall drives clutch transmission structure complicated, and the problem of effort when rotating, simultaneously transmission device of the present utility model has that structure is simple, good hand touch, nonabradable advantage.
Lock gall drives a transmission device for external clutch work, comprises lock gall, in lock gall, is provided with mandrel, especially, also comprises translation shaft and translation shaft cover; Described translation shaft is cylindric; Described translation shaft to be in translation axle sleeve and can to rotate and do axially-movable along himself axis direction by relative translational movement axle sleeve; The side of translation shaft is formed with thread-like groove; Translation shaft puts and is fixed with boss; Described boss is in described thread-like groove; Described mandrel carries out torque transmission to described translation shaft.
Operation principle of the present utility model is as follows:
Drive translation shaft to rotate when the mandrel of lock gall rotates, because translation axle sleeve is fixed on the housing of lock, the rotation of translation shaft is subject to the mating reaction of boss and thread-like groove and can produces himself axially-movable simultaneously.The different rotation directions of mandrel can make translation shaft do the axially-movable of respective direction.Such axially-movable for promoting clutch pushing block, so the transmission between lock gall to clutch pushing block can be realized.Under normal circumstances, when unblanking, translation shaft puts in place toward moving near clutch pushing block direction, then clutch will be in conjunction state; When locking, translation shaft puts in place toward away from the motion of clutch pushing block direction, then clutch will be in from state.
Wherein the drive mechanism of a kind of mandrel to translation shaft is: be also provided with lock gall shifting block, one end of lock gall shifting block is fixed on mandrel, the other end of lock gall shifting block is provided with drive lugs, the end face of described translation shaft is provided with the projection jack coordinated with described drive lugs, and described end face is the end face near mandrel.
The utility model has that structure is simple, driving parts is few, not easily consumes; The principle of application threaded sleeve motion, strengthens transmission effect, and can realize lock gall band dynamic clutch without the need to applying larger power, thrust is large, feel is better.

Detailed description of the invention
Following examples are only the utility model preferably one of embodiment, the restriction not to the utility model protection domain:
As shown in Figure 1, a kind of lock gall drives the transmission device of external clutch work: in lock gall 1, be provided with mandrel 11, and mandrel 11, lock gall shifting block 2 are connected successively with translation shaft 3.Wherein one end of lock gall shifting block 2 is inserted on lock gall 1 by spacing salient point 22 and is fixedly connected with, the other end of lock gall shifting block 2 is provided with drive lugs 21, drive lugs 21 is inserted in the projection jack 31 in translation shaft 3, thus realizes the torque transmission of mandrel 11 pairs of translation shaft 3.Translation shaft 3 is cylinder, and it is in translation axle sleeve 4, and translation axle sleeve 4 is for being fixed in lock body.The side of translation shaft 3 is provided with thread-like groove 32, translation axle sleeve 4 is fixed with boss 41, and boss 41 is in thread-like groove 32.Translation shaft 3 is in the top of clutch pushing block 5.
Under key drives, the mandrel 11 of lock gall 1 will rotate, thus interlock lock gall shifting block 2 and translation shaft 3, thread-like groove 32 and boss 41 mating reaction when translation shaft 3 is rotated along translation axle sleeve 4 and make translation shaft 3 along himself axial-movement.Lock gall 1 rotates and reverse and will translation shaft 3 be caused to stretch out in translation axle sleeve 4 and retraction accordingly in translation axle sleeve 4.If Fig. 2 is the state that lock body is locked, translation shaft 3 is moved toward the direction away from clutch pushing block 5, then clutch is in from state; If Fig. 3 is for rotating unlocking condition, translation shaft 3 pushes clutch pushing block 5 and makes clutch be in conjunction state.As Fig. 4 (a) and Fig. 4 (b) are depicted as translation shaft 3, translation shaft 3 can be plane close to an end face of clutch pushing block 5 also can be different in nature face.
