During normal the use, can or lock dead bolt, can also stir interior handle, open oblique tongue and having ideals, morality, culture, and discipline tongue simultaneously, the transmission process of these two kinds of approach of unblanking is described below in conjunction with Fig. 1 indoor by tapered end 4 unlatchings.

[1] utilize tapered end 4 normally to lock or open four jiaos of tongues and oblique tongue.By key or knob tapered end shifting block 41, after making lockplate assembly 32 move a segment distance along chute, the groove 311 of four jiaos of hyoid tooth plates has been left in screens 321 on the lockplate assembly, continuation is with 41 rotations of tapered end shifting block, promote four jiaos of hyoid tooth plates 312 and move, four jiaos of tongue assemblies 31 can be released or one section of indentation.In the time of the 3rd section, tapered end shifting block 41 is stirred an end of plate 36, utilizes the principle of shouldering bar, and the other end of group plate 36 is stirred in the oblique tongue assembly 33 and contracted, and finishes the unlatching of door lock.

[2] meet an urgent need in the situation of unblanking: indoor, except that utilizing tapered end 4 to open the door lock, handle carries out emergent unlocking in can also utilizing, and opens oblique tongue and four jiaos of tongues simultaneously.When interior handle rotates, drive 35 rotations of shifting block assembly, the block 331 of the oblique tongue assembly 33 of one of them shifting block 351 extruding of shifting block assembly, tiltedly the tongue assembly can contract in chute.Simultaneously, another shifting block 352 of shifting block assembly 35 drives 37 rotations of lockplate return pusher dog, and skateboard component 34 is slided.During 37 rotations of lockplate return pusher dog, the link stopper 322 of its termination extruding lockplate assembly 32 moves lockplate assembly 32, leaves the groove 311 of four jiaos of hyoid tooth plates until the screens 321 of lockplate assembly.This moment, the block 341 of skateboard component began to push four jiaos of gyrus lingulais position pusher dogs 38, made four jiaos of gyrus lingulais position pusher dogs 38 rotation, and the long end of pusher dog is then stirred four jiaos of tongue assemblies 31, made in four jiaos of tongue assemblies 31 and contracted, thereby reach the purpose of emergent unlocking.Tiltedly the tail end of tongue assembly 33 is equipped with oblique tongue top spring 13, and after the shifting block assembly resetted, tiltedly tongue assembly 33 just can recover overhanging state.Between lockplate assembly 32 and double-screw bolt 11-5 extension spring 14 is housed, can makes lockplate assembly 32 after the active force of tapered end shifting block 41 and lockplate return pusher dog 37 disappears, reply lock-out state.
