The mechanical lock is mounted on a portion to sealed mechanism by S1, in another part setting to sealed mechanism
The lockhole to match with the closing piece, when sealed mechanism is in locked state, the closing piece is located in the lockhole；
When S2 needs to unlock, the cryptographic block of each password slot is set on corresponding lattice according to preset password；
Key is inserted by S3 from the jack of shell, so that in each drive rod insertion key in corresponding password slot；Cryptographic block position
Set drive rod corresponding to password slot earlier above will prior to cryptographic block position relatively after password slot corresponding to drive rod reach it is close
The position of code block, thus do not reach the cryptographic block position of corresponding password slot there are also other drive rods, key also to continue to
When preceding insertion, the drive rod of the position of the cryptographic block straight forward movement under the promotion of cryptographic block is had arrived at, drive is connected
Runner rotation, due to small runner and great wheel be it is relatively-stationary, small runner and great wheel rotate together；When all
When drive rod reaches the position of the cryptographic block of corresponding password slot, the slot of all great wheels is located along the same line, and drives
The spring of the other end of bar is also compressed under thrust；
S4 first presses the press section of unlocking mechanism, so that one end of plug-in connection, which all moves inward, is plugged on corresponding small runner
Groove in, then block is removed out of strip card slot；
S5 drives closing piece and strip to move along a straight line to runner direction by closing piece straight line driving mechanism, since block has been moved off card
Slot, and all slots of great wheel are located along the same line and form a channel, therefore strip can be moved smoothly, to lock
Block can also move, until leaving lockhole, realize and unlock；
After S6 unlocks, drive the closing piece and strip toward opposite direction motional feedback original position, strip by closing piece straight line driving mechanism
Key is extracted with after closing piece homing, is lost under drive rod reaction force caused by spring-return original state of key thrust
It moves along a straight line to opposite direction, restores, be displaced outwardly plug-in connection by the press section and be separated with small runner, block
Again it is caught in the card slot；
S7 repeats step S1-S5 when needing again sealed, and after the position of lockhole and closing piece is corresponding, repeating step S6 is
It can；
The method for setting the password of mechanical lock are as follows:
When rigid production is completed, the slot of all great wheels is respectively positioned on same straight line the mechanical lock；
When user's setting code, cryptographic block is placed on the corresponding lattice of password slot and arranges out the password wanted to set up, so
Operated afterwards according to step S1-S5, and by set screw toward interior of shell direction screw in, enable strip always
It is moved to the set screw, each inserted block is inserted in the slot of corresponding great wheel at this time, then all great wheels are all fixed；
Due to being fixed between great wheel and small runner by friction pulley, great wheel is fixed, and small runner still is able to realize rotation；
At this point, cryptographic block is placed in each password slot on corresponding lattice position according to the password that itself wants setting, then lead to
The jack insertion of shell is crossed, corresponding drive rod enters on corresponding password slot；Corresponding to being reached when all drive rods
When on the cryptographic block of password slot, due to cryptographic block to drive rod generate thrust drive rod is moved along a straight line, thus driving with it is small
The gear of runner connection rotates corresponding angle together with small runner together, and the spring for being connected to each drive rod is also compressed into difference
Degree, great wheel at this time, small runner, drive rod and compressed spring state be exactly unlocking condition when password is correct；
It is operated according to step S6, since the spring of the corresponding drive rod of different runners is compressed into various degree, is then being lost
It will be restored after going the thrust of cryptographic block, and small runner is driven to rotate corresponding angle together with great wheel；So afterwards
Each unlocking when, as long as the placement of cryptographic block is correct, identical pushed away when will generate corresponding drive rod with setting code
Power drives small runner to rotate same angle together with great wheel, so that the slot on all great wheels is located at same straight line, thus
It can be realized unlocking；
When with the set screw when needing to unlock, set screw is screwed out, strip is moved to always its end
When being in contact with the inner wall of shell, each inserted block is located exactly in the gap between two slots, will not be inserted in inserting for great wheel
On slot, to will not influence the rotation of great wheel.
6. application method according to claim 5, which is characterized in that the closing piece straight line driving mechanism drives the closing piece
With the method for strip linear motion are as follows: rotation rotation section drives the rotate gear rotation for being connected to the rotation section；It is connected to institute
The rotate gear for stating closing piece drives the closing piece being engaged with to move along a straight line during rotation, is connected to the turning gear of the strip
Wheel drives the strip being engaged with to move along a straight line during rotation；
The method of the drive rod driving runner rotation are as follows: the another side of all small runners is equipped with gear, the tooth on drive rod
Be meshed with gear, when drive rod linear motion when, by gear transmit power, thus driving pinion together with great wheel together
Rotation.
