Annexation is:
Square steel set 4 is located in the stepped counterbore 14 of Internal handle revolving meber 5, when closing the door or have right instructions to open the door, Internal handle
Revolving meber helical structure 15 vertical is fitted with the helical structure vertical of square steel set 4, and square steel set 4 can turn round in Internal handle
Rotate in part 5；
Wherein, Internal handle revolving meber helical structure 15 and the interaction particular content of the helical structure of square steel set 4 include:
(1) pass door state under normal circumstances and have right instructions open the door when: be now Internal handle revolving meber 5 and square steel set 4 each
From helical structure vertical stand terrace bonded to each other, now between the starting point starting point of two helical structures, corresponding central angle is big
In 45° angle；(2) no instruction or during wrong instruction under normal circumstances: rotate outer handle, square steel covers 4 under the drive of square steel
Rotate, but Internal handle revolving meber 5 is motionless, square steel set 4 idle running, the angle between the starting point of two helical structures is with rotation door
The increase of handle amplitude and reduce because now front panel door handle can only turn over 45 ° due to the restriction maximum of other structures, and
Between the starting point of two helical structures, corresponding central angle is more than 45 °, so the cooperation that will not contact with each other；(3) meet with front panel
In the case of removing to violence damage, the rotational angle of square steel set 4 now can be more than 45 °, and it is to lock a door that a direction rotates
Direction, unrelated with helical structure, when rotating backward, after rotational angle is more than 45 ° certain angle, two helical structures
Starting point overlaps, and two helical structures come into contact with cooperation, are rotated further due to the effect of two helical structures, square steel set is ejected
The stepped counterbore of Internal handle revolving meber.
Ejector pin 7 passes through ejector pin spring 8 and compressible knock hole 13 He being arranged on Internal handle revolving meber 5 of ejector pin baffle ring 6
In the radial blind holes of square steel set 4, ejector pin 7 one end is located at outside the stepped counterbore 14 of Internal handle revolving meber 5, and the other end is located at Internal handle
In the stepped counterbore 14 of revolving meber 5；
The cantilever arm a1 of driving member a inserts in the axial draw-in groove 16 on Internal handle revolving meber 5 outer circumference surface；Driving member b's
Cantilever arm b1 inserts in the draw-in groove a2 of driving member a；The draw-in groove b2 of driving member b inserts in the cantilever arm on part 1 inwall in lock body；
Thus Internal handle, Internal handle revolving meber 5, driving parts a and b link into an integrated entity, being capable of synchronous circumferential movement；
One end of square steel sequentially passes through insertion square steel set 4 after the square steel via of part 1 in lock body, driving member a, driving member b
Square steel in the hole；The other end is fixedly connected with outer handle, and Internal handle revolving meber 5 is fixedly connected with Internal handle.
Separately, for cost-effective and space, the side wall of the Internal handle revolving meber 5 of the application design is relatively thin, but due to top
The length of pin 7 is comparatively long, therefore one section that designs ejector pin 7 through Internal handle revolving meber 5 is certain thickness.
Internal handle revolving meber 5 is connected with Internal handle；Driving member a, b are engaged with Internal handle revolving meber 5, and Internal handle can drive
Internal handle revolving meber 5, driving member a, b three are directly realized by unlocking, action of locking.
Outer handle passes through square steel and square steel set 4 is connected, and square steel set 4 and driving member a, b fit but no interact, thus sharp
Can only realize unlocking by instruction with outer handle.
Ejector pin 7 is pushed out Internal handle revolving meber 5 under normal circumstances, and when unlocking, ejector pin 7 is pushed into the radial direction of square steel set 4
In blind hole, square steel set 4 and Internal handle revolving meber 5 can be connected by ejector pin 7.
Set and rotate clockwise inside and outside handle as direction of locking, counterclockwise for unlocking direction；
When locking, unlock in Internal handle direction: unrelated with ejector pin 7 and square steel set 4, Internal handle drives Internal handle revolving meber 5
Rotate, Internal handle revolving meber 5 drives part 1 in driving parts a, b and lock body successively, thus it is dynamic to drive part 1 in lock body to realize
Make；
Using outer handle unlocking three kinds of situations of time-division:
1., when having correct unlocking instruction, the actuation mechanism outside normal door instruction control promotes ejector pin 7, and ejector pin 7 passes through
Knock hole 13 on Internal handle revolving meber 5, ejector pin 7 is pushed in the knock hole 13 of Internal handle revolving meber 5 side square steel set 4
Face circular hole, now by Internal handle revolving meber 5 and square steel set 4 couples together so that Internal handle revolving meber 5 and square steel cover 4 energy for ejector pin 7
Enough do synchronous circumferential movement；Now rotate outer handle, with outer grip palmistry square steel concomitant rotation even, square steel drive square steel set 4 Hes
Internal handle revolving meber 5 rotates；Internal handle revolving meber 5 drives driving parts a, b, thus it is dynamic to drive part 1 in lock body to realize unlocking
Make；
2., when not instructing, ejector pin 7 attonity, if rotating clockwise square steel from outer handle, for action of locking；If the inverse time
Pin rotates, and because now ejector pin 7 does not play the effect of transmission torque, leads to outer grip hand-motion square steel and square steel set 4 idle running.
3. front panel is destroyed, and rotating square steel set 4 can exceed 45 degree, but equally, clockwise for locking a door, counterclockwise then by
In helicoid interaction so that Internal handle revolving meber 5 and square steel set 4 between dally, Internal handle revolving meber 5 can not be by square steel
Set 4 drives unlocks.
Certainly, the present invention also can have other various embodiments, in the case of without departing substantially from present invention spirit and its essence, ripe
Know those skilled in the art and work as and various corresponding changes and deformation can be made according to the present invention, but these corresponding changes and change
Shape all should belong to the protection domain of appended claims of the invention.
