The specific embodiment

See also Fig. 1～6, the column axle center of outdoor handle 110 is connected with an end 124 of connector 120, and this connector also comprises stage casing 121, is that pedestal is provided with a tube connector 122 with it, is provided with equally distributed three projections 123 in its bottom, and top 125 is stretched in the hole 142.

On the other hand; The columnar shaft of inner handle 160 inserts in the hole 154 of ring set spare 150, and two of this ring set spare 150 transplant a cutting and 151 embed respectively to dial and pull in 140 the groove 143, and further embeds in the groove 134 on the cage plate 131.

If pull 110 of outdoor handles clockwise and dally, and any lock body is moved, because it is connected with dialling not have to embed between pulling 140, so can not move so can not further drive lock body 173 and 280 by group pulling 140 drive shifting block 12a.

If pull inner handle 160 clockwise, then through assembly 150,140 interlocks, the aixs cylinder that makes plate 130 drive on the bullet piece 171 moves, and bullet piece 171 and lock body 173 drives is moved to right again; On the other hand, plate 145 also clockwise rotates, its end drives shifting block 270 and rotates counterclockwise, shifting block 270 drives the frid that links to each other with upper lock body 280 again, make upper lock body 280 move right, promptly by pulling the single stepping of inner handle 160 clockwise, the former lock body 173 and 280 that is in blocking is all moved right, make door lock be in opening.

In order also to open the door outdoors, need other supplementary structure, see also shown in Fig. 7-10: door handle core body 10 of the present utility model comprises hole core 11 and cover core 12, hole core 11 is provided with projection 117, offer the groove (not shown) on the cover core 12, inserting door bolt 113 can stretch in the hole of cover 12 by this groove, and this other end of inserting door bolt 113 is resisted against on the reed 125d of spring, and hole core 11 inserts in the hole of cover core 12; Also comprise spring shell fragment combining structure, it comprises bullet fork 50, following shell fragment 40d, and last shell fragment 40, pressing plate 30 is provided with down press strip 30b, top board 30a, they are with same axle center fixed combination.

Wherein, the thread 20a overlap joint on the axle of the end of this top board 30a and motor 20 cooperates, and can move up and down with the rotation of 20 on motor.Following press strip 306 and following shell fragment 40d butt, last shell fragment 40 and upper lock body linked block 50 butts.

During use, from importing correct unlocking cipher outdoors or with behind the key unlocking, meeting trigger control circuit (not shown) is sent signal to motor 20 makes the axle of motor 20 begin rotation, thread 20a on the axle drives and the top board 30a of its butt moves down, naturally also move down with the following press strip 30b of 30a one, thereby will press down with the following shell fragment 40d of its butt is past, further, following shell fragment 40d will insert door bolt 113 toward pressing down, insert door bolt 113 and down progress in the hole of cover core 12, and arrival and hole core 11 position contacting, and lean on mutually with projection 11 on the hole core 11, at this moment, pull outer door handle, propped up by projection 11 owing to insert door bolt 113, the rotation of hole core 11 also drives cover core 12 and rotates, what be provided with on the cover core 12 pulls piece 12a also in company with rotating, 91 at the angle of pulling that pull on the upper lock body at its end angle rotates counterclockwise, and then latch 60 moves right (down lock body 80 is also together moved right by drive) on driving, to the right-hand member stop, lock is opened, and can open the door.

The end of the linked block 50 that links to each other with last latch 60 moves to right-hand member, remains static; At this moment if close the door, the bent angle of then going up on the shell fragment 40 colludes for a short time and can a motive force be arranged left to linked block 50, adds that latch 60 itself just has spring structure, so the elastic force of spring is just taken back left end point with upper lock body, lock body is closed.

Meanwhile, spring shell fragment combining structure is reversion original position (motor 20 insert to stop operating when door bolt 113 is conflicted hole core 11) also, promptly inserting door bolt 113 is upwards mentioned, break away from hole core 11 and projection 117, at this moment then can not drive cover core 12 and rotate pulling outdoor handle outdoors, upper lock body is moved to right, just hole core 11 idle running, can not reach the purpose of opening the door, unless input correct password outdoors or opening the door with key, the control motor rotates once more, and drive slotting door bolt 113 and move down ... following operation process is the same.

See also Figure 12～18, for simplicity's sake, about the not expression in the drawings of door handle, the movable structure of inserting door bolt and being connected with motor; When pulling inner handle, or from importing correct unlocking cipher outdoors or according to above-mentioned operating principle outdoor handle and inner lock body being fused with key operated, pull outdoor handle then, two lock bodies 40,60 are driven to the right be retracted to stop by pulling piece 12a, can open door this moment, unclamp outdoor handle, because the effect of shell fragment 55, lock body 40 is maintained at this dead-centre position; But compressed spring 63 resiliences eject latch 60 left; Because latch 60 is that the cross section is leg-of-mutton latch, push it against doorframe a little less than this moment, latch 60 is subjected to after the percussion indentation to the right again, the jacking block 73 that links to each other with latch 60 moves right, shell fragment 75 is close in its lower end simultaneously, shell fragment 75 has upwards pushing and pressing effect to it, and its top dog 73a is rotated counterclockwise the back and links the arrival stop with the top dog 71a of shifting block 71 mutually; Latch 60 is by behind the doorframe, resistance disappears, so it ejects (entering the doorframe lock body dead slot district that is mated) again left under the back stretch effect of spring 63, driving jacking block 73 simultaneously is moved to the left, the top dog 71a that top dog 73a drives on the shifting block 71 again is moved to the left, and then lock body 40 also driven left enter the doorframe lock body dead slot district that is mated, so with on the door lock.
