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

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.
