Also be provided with in described housing and can rotate with lock core assembly 5 and the movable plate 20 that moves left and right, be specially: described lock core assembly 5 is provided with the dead bolt 21 rotated together with lock core assembly near locking plate one end, dead bolt 21 is eccentric structure, and be all arranged to arc at its two ends place, described lock housing 4 is provided with fluting 22, described dead bolt 21 can pass fluting 22 when rotating and abut against with described movable plate 20, described movable plate 20 is connected with the second spring 23 abutted against with housing away from lock housing 4 one end, dead bolt pass fluting with movable plate abut against time, movable plate is toward moving right, when dead bolt does not abut with movable plate, movable plate is past under the effect of the second spring to be moved left.
Described movable plate 20 is provided with some can to move left and right with movable plate and the plunger tip 24 that moves up and down, described plunger tip 24 with described character wheel core 15 one_to_one corresponding and can with character wheel core 15 tabling.Be specially: described movable plate 20 is provided with the corresponding groove 25 of some and described plunger tip, described groove both sides are that inclined-plane is arranged, inclined-plane is provided with and is beneficial to plunger tip moving left and right and move up and down with movable plate, in the present embodiment, groove 25 on movable plate 20 is respectively 4 with the number of plunger tip 24, plunger tip can be moved plate jack-up under the movement of movable plate, and plunger tip can be embedded in the groove 16 of character wheel core by after jack-up, thus character wheel core cannot be rotated.Top cover 26 is arranged with outside described plunger tip 24, described plunger tip is that inverted T shape is arranged near movable plate one end, described top cover is inwardly convexly equipped with bulge loop 27 away from movable plate one end, this bulge loop can abut against with the plunger tip one end arranged in inverted T shape, thus plunger tip can not be separated with top cover, position-limiting action is played to plunger tip, the described plunger tip 24 be positioned at inside and outside top cover 26 is arranged with respectively the first spring 28 and the 5th spring 34, when making plunger tip by jack-up, a cushion effect is had between plunger tip and character wheel core, wearing and tearing can not be caused when ensureing that plunger tip cannot embed groove, and can plunger tip be made smoothly to be embedded in groove.
In the present embodiment, described housing is also provided with shifting part 29, described shifting part is provided with and can moves left and right with it and the fixed central spindle 30 that moves up and down, and described fixed central spindle 30 moves up and can abut against with described character wheel core.Be specially: described shifting part 29 is provided with protruding platform 31, protruding platform 31 side that is connected with shifting part 29 horizontal ends is that inclined-plane is arranged, inclined-plane is provided with and is beneficial to moving up and down of fixed central spindle 30, mandrel bulge loop 32 is convexly equipped with in the middle of described fixed central spindle 30, be positioned in the fixed central spindle above mandrel bulge loop 32 and be arranged with mandrel springs 33, described fixed central spindle 30 up moves, move to certain altitude to abut against with described character wheel core, thus character wheel core cannot be moved, can not Modify password, in the present embodiment, shifting part 20 is near lock housing 4.
When coded lock is in unlocking condition, stir character wheel 18, select the code word adapted, determine four passwords, now lock housing projection 10 and geocoded activity block 11 abut against, under the promotion of lock housing projection 10, geocoded activity block 11 is past together with character wheel mandrel 9 to move right, projection 17 on character wheel mandrel 9 is positioned at the groove 16 of character wheel core, character wheel core 15 is past under the drive of character wheel mandrel to move right, character wheel core and character wheel are separated, when stirring character wheel and selecting password, character wheel rotates and character wheel core does not rotate, then rotate knob 7 and drive lock housing 4 to rotate, close coded lock, now, lock housing projection does not abut with character wheel mandrel, character wheel mandrel is at the 3rd spring 13, under the effect of the 4th spring 14, initial position got back to by character wheel mandrel and character wheel core, character wheel core now matches with character wheel, character wheel can drive character wheel core to rotate together, projection on character wheel mandrel and groove are separated, such four passwords just set, after upsetting code word, when not finding correct password, character wheel core matches with character wheel, but the projection on the groove of character wheel core and character wheel mandrel is not on the same line, lock housing all abuts against with character wheel mandrel, thus lock housing and knob cannot be rotated.
When fixed central spindle 30 is positioned at shifting part 29 horizontal one end, fixed central spindle does not abut against with character wheel core, and the password set this time is common key, and who can open according to common key or close coded lock, and can common key be revised, when shifting part is stirred, fixed central spindle is moved up along protruding platform 31, fixed central spindle and character wheel core are abutted against, character wheel core cannot move, after setting password, just cannot reset password, the password set this time is private code.
When coded lock is in closed condition, operating personnel forget Password, and cannot open lock under normal circumstances, use emergency key 35 can find the password of setting.Use correct emergency key, insert in lock core assembly 5, rotational lock core assembly, thus drive dead bolt 21 to rotate, dead bolt passes lock housing and abuts against with movable plate 20, movable plate moves right under the effect of dead bolt, thus will plunger tip 24, top cover 26 jack-up of movable plate groove 25 be positioned at, now rotate character wheel, character wheel drives character wheel core, until plunger tip embeds in the groove of character wheel core, namely have found the password of this character wheel, rotate three remaining character wheels successively, find the password of setting, then according to password unlocking.
When the password set is private code, be in unlocking condition, after having dialled disorderly password, operating personnel can adopt private key 36 to give original password for change, the way of operation, with above-mentioned, inserts lock core assembly with private key 36, in the groove that plunger tip is embedded on character wheel core, character wheel cannot be rotated, and the code word at this moment shown is the password of setting.
Described lock core assembly 5 is prior art, and this is no longer going to repeat them.
A kind of coded lock that the present invention obtains, can be common key and private code by the password setting of coded lock, meet the demand of different occasion, and can ensure that operating personnel are after forgetting or being revised new password by other users, can password be given for change and revise, safe and reliable, easy to operate.
