As shown in Figure 2 and Figure 3, driving mechanism 42 is a part of arrangement of clutch 4, and the arrangement of clutch 4 includes follower 41, driving mechanism 42, reversing key 43, cover board 44, follower 41, the socket of driving mechanism 42 and clearance fit.It is described driven The generally hollow step-like cylindrical body of mechanism 41, including pedestal 411, the top of pedestal 411 are provided with protruding portion 412.In order to Other mechanisms can be sent power to, follower 41 is hollow structure, which generally selects square or three It is angular, that is, perhaps triangle axis hole is inserted into when square shaft or Axis Tripod in the center location setting square shaft hole of follower 41 Behind square shaft hole or triangle axis hole, follower 41 can drive other components to move.Protruding portion 412 is certainly introversive from central axis It is divided into two layers outside, internal layer 413 is hollow cylinder, and effect is further external transmitting forces;Outer layer 414 is to lack with first Mouthfuls 415 hollow cylinder, effect are and commutation key contacts.Above-mentioned central axis corresponds to the A axis in Fig. 9.The outer diameter of pedestal 411 The typically larger than outer diameter of protruding portion 412, the position that driving mechanism 42 and follower 41 may be implemented in this way are kept;In certain feelings Under condition, the relative position of driving mechanism 42 and follower 41 can also be kept by other components, if it does, pedestal 411 outer diameter and the outer diameter of protruding portion 412 can be designed freely, or even the two design is structure as a whole.
The driving mechanism 42 is hollow cylindrical body, which is circle.The outer diameter of driving mechanism 42 is equal to bottom The outer diameter of seat 411, the internal diameter of driving mechanism 42 are slightly larger than the outer diameter of protruding portion outer layer 414.Protruding portion 412 passes through driving mechanism 42, protruding portion outer layer 414 is bonded the inner wall of driving mechanism 42, at this point, driving mechanism 42 and protruding portion 412 can freely revolve relatively Turn, therefore driving mechanism 42 is unable to drive follower 41 while moving.
Free-revving engine of the invention first is that, by driving mechanism 42 drive follower 41 move simultaneously, can general The power generated on handle is passed to from mechanism 41 is determined, to be further driven to the movement of other mechanisms.
In order to realize the drive follower 41 of driving mechanism 42 while move, the second notch is set on driving mechanism 42 421, after follower 41 and the socket of driving mechanism 42, the part on outer layer 414 except first notch 415 constitutes inner ring 416, the part on driving mechanism 42 except second notch 421 constitutes outer ring 422.Inner ring 416 and outer ring 422 are not limiting In the case that device acts on, the two opposite can be rotated freely, and driving mechanism 42 is unable to drive follower 41 while moving.Cause This, needs that a limiting device is arranged on inner ring 416 and outer ring 422, realizes that driving mechanism 42 drives follower 41 simultaneously Movement.
An important innovative point of the invention is limiting device described below.
Limiting device used by the present embodiment is a reversing key 43, and the reversing key 43 is one section of on-deformable circle Arcuation.The front setting regulating device 431 of reversing key 43, fixed column 432 is arranged in the back side.One is arranged on second notch 421 admittedly Determine hole 423, fixed column 432 is inserted into fixation hole, and can be rotated freely in fixation hole 423.Certainly, it is set on the second notch Fixed column is set, fixation hole is set on reversing key, identical technical effect also may be implemented.
When reversing key 43 rotates clockwise, one end 434 contacts simultaneously with the first notch 415 and the second notch 421, That is, being contacted simultaneously with inner ring 416 and outer ring 422.Since reversing key 43 and inner ring 416 and outer ring 422 are to be unlikely to deform material Preparation, so that reversing key 43 can not continue around B axle rotation, it, can as a result, when driving mechanism 42 is rotated clockwise around A axis To drive follower 41 while move.On the contrary, when reversing key 43 rotates counterclockwise, 433 first notch of one end, 415 He Second notch 421 contacts simultaneously, that is, while being contacted with inner ring 416 and outer ring 422.Since reversing key 43 is with inner ring 416 and outside Circle 422 is to be unlikely to deform material preparation, so that reversing key 43 can not continue to rotate around B axle, as a result, when driving mechanism 42 encloses When being rotated counterclockwise around A axis, follower 41 can be driven while being moved.
The novelty of reversing key described in the present embodiment is embodied in reversing key around a fixed position rotation, is rotating During, some contact of reversing key can be contacted with the first notch 415 and the second notch 421 simultaneously, to limit master The free movement of motivation structure and follower clockwise or counter-clockwise, so that driving mechanism 42 drives follower 41 at some It is moved while direction.
After reversing key 43 is rotated in place in order to prevent, then opposite direction rotation, in 421 junction of outer ring 422 and the second notch Conduit 424 is set, and conduit 424 is provided with spring 425 and steel ball 426, a termination of steel ball 426 and reversing key 43 from inside to outside Touching.Said mechanism design ensures that reversing key 43 can not reversely rotate in the case where the interference of no larger external force.
Reversing key 43 rotates the range for excessively exceeding the first notch 415 and the second notch 421 in order to prevent, in reversing key The back side is provided with limited post 435, corresponding, limiting slot 427 is provided on the second notch 421, limited post 535 is in limiting slot It is movable in 427, so that it is guaranteed that reversing key 43 can not excessively rotate.Preferably, limited post 435 and the respectively setting two of limiting slot 427.
In addition, limiting slot to be set to the back side of reversing key, also can be achieved on if limited post is set to the second notch Identical technical effect.
It converts in direction of the regulating device 431 for reversing key 43.Due to there is the active force of steel ball 426, need biggish The external direction conversion for being just able to achieve reversing key 43.It sets regulating device to linear type groove shapes in the present embodiment, The shape, which is suitable for rising using a word, to be adjusted.Obviously, regulating device is also designed to other shapes.
It is fixed in order to encapsulate above-mentioned component, the top of driving mechanism 42 is provided with a circular cover board 44, it is provided with adjustment hole 441 on cover board 44 and regulating device 431 cooperates.
When upper lift handle 1, turns to 43 one end of key and contact arrangement of clutch Internal and external cycle simultaneously, arrangement of clutch is made to be in the shape closed State, arrangement of clutch drive follower rotation, door are locked.After handle 1 commutates, rotation is played using a word and turns to key, make to turn Arrangement of clutch Internal and external cycle is contacted simultaneously to the key other end, state of the arrangement of clutch still in conjunction, arrangement of clutch band when upper lift handle Dynamic follower rotation, locks door.
Above-mentioned technical proposal may be implemented no matter the direction of handle, may be implemented lift handle realization lock.To make It obtains household intelligent door lock and is more easily suitable for the left and right door opened, to expand the scope of application of lockset.
It is directed to the mechanism of reversing key, other several embodiments are given below.It is mentioned above, the novelty of reversing key Reversing key is embodied in around a fixed position rotation, during rotation, some contact of reversing key can simultaneously with First notch 415 and the second notch 421 contact, thus limit driving mechanism and follower clockwise or counter-clockwise from By moving, so that driving mechanism 42 drives follower 41 to move while some direction.
Around above-mentioned thinking, can be realized basic fundamental effect reversing key should include one can rotate freely consolidate Determine the point of rotation, the fixed point of rotation is rotated around B axle shown in Fig. 8;Further include one can simultaneously with the first notch 415 and The first contact point of second notch 421 contact.
When first contact point simultaneously with the left contact of the first notch 415 and the second notch 421 when, driving mechanism can band Dynamic follower clockwise movement;When arrangement of clutch needs to commutate, that is, need driving mechanism that can drive the follower inverse time When needle movement, need to rotate a certain angle reversing key around B axle so that first contact point simultaneously with the first notch 415 and The right contact of second notch 421.
The design of above-mentioned fixed point of rotation combination first contact point can satisfy the basic demand of clutch reversing, still, Disadvantage is also apparent, and arrangement of clutch is often in a closed space, by first contact point from the first notch 415 and The left side spin of two notches 421 goes to the first notch 415 and the right side of the second notch 421 generally requires biggish space, increases The design difficulty and manufacturing cost of arrangement of clutch.
For this purpose, for contact point limit is required at left and right sides of the first notch 415 and the second notch 421, it is preferred to commutate Key scheme is, including a fixed point of rotation and symmetrical first contact point, the second contact point, the first contact point it is same When left contact with the first notch 415 and the second notch 421 when, driving mechanism can drive follower clockwise movement; Second contact point simultaneously with the left contact of the first notch 415 and the second notch 421 when, driving mechanism can drive driven Mechanism counterclockwise movement.The shape of the fixed point of rotation and first contact point, the second contact point coupling part seems not important, but It is, it is emphasized that, no matter use and shape, reversing key should be unlikely to deform, otherwise can not achieve technical effect.
