Operating principle of the present utility model is presented below:

The action 1, when the people opens the door without, at first press the password on the code keypad 32, connect electromagnetic coil 317, make video disc 318 together with double wedge 316 by adhesive, double wedge 316 is meshed with recessed tooth 314, this moment, main shaft 319 rotated 90 ° thereupon, main tongue pin 7 can be withdrawn from kingpin bore with outer handle 331 half-twists.At this moment, press the cryptographic key on the keyboard 32, make electromagnetic coil 317 outages, video disc 318 and double wedge 316 are got back to the origin-location under stage clip 315 effects, break away from recessed tooth 314, if rotate outer handle 331 again, main shaft 319 will can not rotate with outer handle 331, and promptly main tongue pin 7 will be held open state.In order to open auxilliary tongue pin 23, also to press outer button 211, the displacement of outer button 211 makes slide 212 rotations, the ring seat 213 that is attached thereto is rotated thereupon, ring seat 213 drives tooth bar 214 and moves down, as shown in figure 10, tooth bar 214 moves down into dotted line position by solid line position, moving down of tooth bar 214 makes gear 215 half-twists that are engaged with, drive auxilliary axle 216 half-twist thereupon, thereby can make the auxilliary tongue pin 23 that was in closed condition originally withdraw from auxilliary pin-and-hole, auxilliary tongue pin 23 becomes opening, has promptly finished the process of opening the door.

The action 2, when the people locks a door without, the password on the keypad 32 at first, make electromagnetic coil 317 energisings, video disc 318 and double wedge 316 are by adhesive, thereby double wedge 316 is meshed with recessed tooth 314, with outer handle 331 half-twists, main shaft 319 rotates 90 ° thereupon, main tongue pin 7 can be inserted kingpin bore; Meanwhile, with reference to Figure 10, the cam 3191 that is fixed together with main shaft 319 also rotates 90 °, cam 3191 ejection tooth bars 214 are to top offset, move to position shown in the solid line by position shown in dotted lines in Figure 10, make gear 215 half-twists, the auxilliary axle 216 that is fixed together with gear 215 also changes 90 °, thereby drive auxilliary tongue pin 23 and insert auxilliary pin-and-hole, the password on the keypad 32 makes electromagnetic coil 317 outages again, video disc 318 and double wedge 316 are got back to original position under stage clip 315 effects, break away from recessed tooth 314, main tongue pin 7 and auxilliary tongue pin 23 are all by locked, and the action of locking a door is once finished.If rotate outer handle 331 again, main shaft 319 will rotate no longer thereupon.

When the electronic circuit of action 3, the control electromagnetic coil 317 that connects when keyboard 32 breaks down, also available key is opened door, as long as with rotation in the lock core 332 at the outer handle of key insertion 331 centers, the inclined-plane gear 311 that is connected with lock core 332 is rotated, because of will promoting inclined-plane gear 312, the effect on inclined-plane moves inwards, thereby barb 313 is moved and be meshed with double wedge 316 by recessed tooth 314, by rotating outer handle 331 in the above-mentioned action 1, can open main tongue pin 7, press the button 211 again, can open auxilliary tongue pin, thereby realize opening the door action.

Action 4, when the people locks a door in doors, rotatable inner button 24 drives auxilliary axle 216 rotations, makes auxilliary tongue pin 23 insert auxilliary pin-and-hole locking.
