The specific works principle of the present embodiment is as follows:
1, to lock process
At closing time, after the trigger architecture a23 of door lock collides doorframe, described trigger architecture a23 makes the locking of latch-up structure releasing to door lock of door lock, then described rotation seat a10 drives described dead bolt installing plate a8 towards locking out direction motion by described tooth bar a9 under the effect of described disc spring a22, and then drive the lock bolt structure of door lock to lock out, thus complete the process of locking of door lock, now, described interior handle is rotated towards direction of locking, described interior handle drives described handle axle a1 to rotate, the described handle shifting part a2 being positioned at described first idle running groove a4 and described second idle running groove a6 rotates under the drive of described handle axle a1, but because the arc length corresponding to notch of described first idle running groove a4 is greater than the arc length corresponding to notch of described second idle running groove a6, so when the cell wall of described handle shifting part a2 and described second idle running groove a6 offsets, described handle shifting part a2 does not offset with the cell wall of described first idle running groove a4, therefore described handle shifting part a2 only drives described insurance impeller a5 to rotate, described insurance impeller a5 drive under the cooperation of described guiding skewed slot a16 and described guide finger a17 described safety plate a13 towards insurance lock direction motion, when described guide finger a17 moves to the end of described guiding skewed slot a16, the described Embedded Division a19 of described safety plate a13 just in time embeds in the groove a12 of described rotation seat a10, thus described rotation seat a10 is locked, and then by the described tooth bar a9 be meshed with described rotation seat a10, described dead bolt installing plate a8 is locked, even if also door cannot be opened at outdoor application key like this, complete the process of locking of described safety structure, as shown in Figure 6 and Figure 8.
2, releasing process
When needs open the door, first the locking contacting described safety structure is needed, namely described interior handle is rotated towards unlocking direction, described interior handle drives described handle axle a1 to rotate, the described handle shifting part a2 being positioned at described first idle running groove a4 and described second idle running groove a6 rotates under the drive of described handle axle a1, but because the arc length corresponding to notch of described first idle running groove a4 is greater than the arc length corresponding to notch of described second idle running groove a6, so described handle shifting part a2 only offsets with the cell wall of described first idle running groove a4 at the beginning, therefore described handle shifting part a2 only drives described insurance impeller a5 to rotate, described insurance impeller a5 drives described safety plate a13 towards the motion of insurance unlocking direction under the cooperation of described guiding skewed slot a16 and described guide finger a17, thus described safety plate a13 is being deviate from from described groove a12, and rotate away from described rotation seat a10 under the cooperation of described insurance impeller a5 and described first fit structure,
After described safety structure unlocks, continue to rotate described handle axle a1 towards unlocking direction, the cell wall of described handle shifting part a2 and described first idle running groove a4 offsets, and drives described handle actuator a3 to rotate, thus is driven in the lock bolt structure retraction lock housing of door lock by described handle actuator a3; And then complete whole door opening process, as shown in figures 7 and 9.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain of the invention.
