Below set forth in detail the operating principle of lock core:

When the lock core locking of this electronic anti-theft door lock; Promptly when shifting block 301 changes counterclockwise, be positioned at shifting block 301 lower surfaces projection 315 promote to be sleeved on rotating counterclockwise of gear plate 314 on the shifting block 301, when gear plate 314 rotates; Second gear 204 that the connecting lever 202 that first gear, 318 drives that have on it are engaged with is provided with rotates; Thereby the front end that drives connecting lever 202 rotates, and the side's of promotion tongue 201 stretches out square bolt hole 109, realizes locking a door.

Simultaneously; It is safety tongue 401 indentations second square holes 108 that safety tongue assembly 400 will be pressed into lock shell 100; The insurance hyoplastron 403 of suit and insurance jam plate 110 are thrown off on the safety tongue assembly 400 at this moment, and the front end of insurance jam plate 110 turns to and oblique tongue assembly 500 contacts side surfaces under the elastic force effect of elastic reset member; Propping up oblique tongue assembly 500 button bits makes and plays the effect of self-locking anti-plug by oblique tongue assembly 500 side plate 102 of withdrawing.

As shown in Figure 4; When the lock core of this electronic anti-theft door lock was opened, promptly when shifting block 301 changes clockwise, projection 315 promotions of shifting block 301 lower surfaces were sleeved on clockwise rotating of gear plate 314 on the shifting block 301; When gear plate 314 rotates; Second gear 204 that the connecting lever 202 that first gear, 318 drives that have on it are engaged with is provided with rotates, thereby the front end that drives connecting lever 5 rotates, thus the side's of promotion tongue 201 withdrawal side plates 102.

Simultaneously; The projection 315 of shifting block 301 upper surfaces promotes to be sleeved on going up on the shifting block 301 and dials clockwise rotating of plate 313; Go up group plate 313 first hypotenuses 316 promotion insurance jam plates 110 and rotate counterclockwise certain angle; Make insurance jam plate 9 its front ends and the button bit of oblique tongue assembly 500 throw off, the anti-plug auto-lock function is removed.Go up group plate 313 and be rotated further the oblique tongue assembly 500 withdrawal side plates 102 of baffle plate 506 drives that its front end is stirred oblique tongue junction plate 501 afterbodys, realize opening the door.

When the lock core mechanical key of this electronic anti-theft door lock is opened, and be in when closing the door state when lock core, thereby the related tapered end shifting block 103 of rotary machine key rotates together; After tapered end shifting block 103 turns an angle, the projection that the side's of touching tongue connecting lever 202 is provided with, thus the side's of stirring tongue connecting lever 202 makes it rotate 180 degree; Connecting lever 202 front ends are rotated, and tongue 201 withdrawal side plates 102 in the side's of promotion are rotated further mechanical key again and then continue to drive 103 rotations of tapered end shifting block; Behind this moment side's tongue 201 withdrawal side plates 102, junction plate 203 also moves on to the position near tapered end shifting block 103 thereupon together, after tapered end shifting block 103 turns an angle again; Touch second bending part 205 that cooperates with tapered end shifting block 103 that junction plate 203 tops are provided with; Rotate thereby drive junction plate 203, drive then to go up and dial plate 313 forward rotation, realize opening the door.

Because the clutch by Electric Machine Control of the lock core of this electronic anti-theft door lock is inside and outside complete symmetrical structure; Be the coaxial respectively rotating clutch yokes 302 that are set with of shifting block 301 upper and lower sides; And shifting block 301 1 sides are provided with the clutch block that can control clutch yoke 302; 301 of this clutch block and shifting blocks are provided with elastic reset member 307, and in the present embodiment, elastic reset member 307 is a stage clip; Wherein second square hole 311 of a clutch yoke 302 is connected with the outer handle square shaft of door lock, and second square hole 311 that the interior handle square shaft of door lock passes another side clutch yoke 302 is connected with first square hole 310 of shifting block 301; When the motor in the electric machine assembly 600 was just changeing, clutch block was pushed in the shifting block 300 and meshes with clutch yoke 302, made shifting block 301 and clutch yoke 302 to realize the lock core open function by interlock; Because clutch is symmetrical structure, therefore two-wayly all can realize.

Like Fig. 5 and shown in Figure 6; Oblique tongue junction plate 501 in the oblique tongue assembly 500 of the lock core of this electronic anti-theft door lock is provided with gear 502; Turning set is equipped with limiting plate 104 in the lock shell 100; When limiting plate 104 is parked in the below of fan groove 105 of lock shell 100, opens oblique tongue assembly 500 gear 502 that rear position margining plate 104 withstands on the oblique tongue junction plate 501 that puts in place and make the front end of oblique tongue assembly 500 be parked in the square hole of side plate 102; When limiting plate 104 is parked in the top of the fan groove 105 of locking shell 100; Open oblique tongue assembly 500 rear position margining plate 104 that puts in place and can not withstand the gear 502 on the oblique tongue junction plate 501; Oblique tongue assembly 500 can continue indentation to be deviate from the square hole by side plate 102 fully, and this moment, tiltedly tongue assembly 500 placed lock shell 100 and the breach that locking closure 101 is provided with fully, rotated oblique tongue 503 1 hundred 80 degree; Unclamp oblique tongue assembly 500; In first square hole 106 of effect declivity tongue assembly 500 by side plate 102 of back-moving spring 504, stretch out, 104 groups of limiting plates are gone back to the below of the fan groove 105 of lock shell 100, promptly accomplish Inclined bolt direction changing.Whole process need not dismantled lock shell 100 can realize Inclined bolt direction changing, therefore easy to operate.

Above embodiment only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement in view of the above, can not limit the protection domain of the utility model.All equalizations of being done with the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
