The utility model mechanical code lock operating principle is:

The utility model operating principle mainly is to promote locking bolt by password key to insert cylinder plate and lock mechanism, unlocking mechanism and stir the cylinder plate displacement realization that combines and lock and unblank.

(1) be provided with or change password:

1, unclamp bolt 6 and pull down lock bottom plate 5, inwardly pinch two armed levers 18 of the horizontal trailing arm 14 of tight resetting means B from both sides, take off horizontal trailing arm 14, withdraw from restoring board 13, behind this moment lock core on the plate 4 locking bolt 11 in 36 locking bolt holes 20 and the hole all appear.

2, numerical selection is provided with the key passwords of mechanical lock voluntarily, selects 7 numbers to form password with interior numeral usually and enough maintains secrecy.The locking bolt 11 of this yard position is inserted in the locking bolt hole 20 towards the direction of lock panel according to flat handle 25, and the locking bolt of all the other non-password positions then revert all inserts in the locking bolt hole 20.Referring to accompanying drawing 19, among the figure from left to right the 1st, 3,5 three key be the button that password is set, the 2nd, 4,6 three key is non-password key.And then reduction, install behind the lock body plate 5 and restoring board 13 and horizontal trailing arm 14, tight a bolt 6.

(2) latch:

1, the C of mechanism is locked in turn, to lock handle or angle of right rotation left, rotating shaft 28 drives shifting block 29 deflections, the lock pin 33 that promotes both sides outwards moves, and rotating shaft simultaneously 28 drives jacking block 27 deflections, and plate 3 moves up in the jack-up lock core, when jacking block 27 fall into lock core plate 3 bottoms lock groove 23 time, block, lock pin 33 overhanging location were prevented from and can't be returned by the elastic force of spring 31 this moment.

2, it is outside to pull moving resetting means B, and reseting handle 8 drives horizontal trailing arm 14 and restoring boards 13, pushes 36 locking bolts, inserts in the locking bolt hole 20 of three layers of jam plate 2,3,4, and lock core is connected into an integral body.Referring to accompanying drawing 19, the 1st, 3,5 three locking bolt 11 is in shown in the solid line position from left to right.Locking bolt 11 is locked with plate in the lock core, can not upper and lowerly move, and lock C of mechanism and unlocking mechanism A effect all out of hand this moment, unclamps reseting handle 8, and resetting means sets back.

(3) unblank:

1, presses each password key 9 one by one according to predefined code number.Referring to accompanying drawing 19, locking bolt 11 is pressed to dotted line position among the figure by button 9, touches the location with restoring board 13, locks the 11 locking bolt holes of withdrawing from plate 3 in the lock core fully this moment, and plate 3 can upper and lowerly move freely under unlocking mechanism A promotes in the lock core.

2, rotation unlocking mechanism A, left or right rotation unlocking handle 7, drive shifting block 35 deflections of unblanking through rotating shaft 34, plate 3 rises mobile in the promotion lock core, the shifting block of locking the C of mechanism 27 that its underpart is locked in the groove 23 breaks away from, lose the positioning control to lock pin 33, lock pin 33 is return automatically under the elastic force effect of spring 31 and is resetted, and realizes unblanking.

Strong lock function when (four) pressing the wrong button, when mistake was pressed the button of non-setting code number, then the square column of locking bolt 11 inserted plate 3 in the lock core, and promptly can't turn unlocking handle 7 promote plate 3 in the lock core this moment.Referring in the accompanying drawing 19 from left to right shown in the 6th locking bolt 11 dotted line.

The utility model is particularly suitable for as the safety cabinet lock.Increase corresponding accessory, also can make safe-guard door lock.The utility model has the advantages that and adopt the mechanical cipher button not open the lock with the key, also do not have the lockhole that exposes, prevent the pirate of the open lock effectively and stop up lockhole destruction lock, structure is firm, and is not fragile, easy to use, installs easily.
