Described pillar is provided with cross bar 23, on described cross bar 23, cover has spring 14, a tooth bar 15 that is provided with concave shape groove withstands on described spring 14, described locking bar 12 hooks on the concave shape groove of described tooth bar 15, gear 16 is set in the same level of described tooth bar 15 and tooth bar return device 26 is set, described tooth bar return device 26 one end reach outside shell 20 by the through hole of shell 20, and the other end to the distance of tooth bar 15 is no more than the length that described tooth bar return device 26 reaches outside shell 20.
Mechanical code lock is provided with spacing mandril 25, and described spacing mandril 25 is connected with described push rod 1, and described spacing mandril 25 the place aheads arrange ball grooves 2, have 11 balls 11 in described ball grooves, and the space in ball grooves 2 only can hold a spacing mandril 25 and enter.
In shell 20, be provided with top base 6, described top base 6 is provided with 6 pellets 5, and described in each, pellet below is provided with spring 4; On described top base, 6 are provided with upper shifting board 3, and described upper shifting board 3 is magnetic material, and described upper shifting board has groove, in described groove, is provided with spring, and on described spring, being pressed with top is the briquetting at oblique angle on one side; Top base is provided with baffle plate, and described return driving lever 7 extends to below described top base 6, and described return driving lever 7 is provided with pressing plate on the identical horizontal plane of the briquetting with upper shifting board 3.
When password is set, shell 20 tops can be opened, use the instruments such as little cleek, by regulating the upper-lower position of driving lever 2 that password is set, for example: the password presetting is " 743598 ", shift first plectrum 2 indicating on the push rod 1 of numeral " 7 " onto push rod 1 below, all the other driving levers on this push rod 1 are shifted push rod 1 top onto; Shift second driving lever 2 indicating on the push rod 1 of numeral " 4 " onto push rod 1 below, all the other driving levers 2 on this push rod 1 are shifted push rod 1 top onto; Shift the 3rd driving lever 2 indicating on the push rod 1 of numeral " 3 " onto push rod 1 below, all the other driving levers 2 on this push rod 1 are shifted push rod 1 top onto; Shift the 4th driving lever 2 indicating on the push rod 1 of numeral " 5 " onto push rod 1 below, all the other driving levers 2 on this push rod 1 are shifted push rod 1 top onto; Shift the 5th driving lever 2 indicating on the push rod 1 of numeral " 9 " onto push rod 1 below, all the other driving levers 2 on this push rod 1 are shifted push rod 1 top onto; Shift the 6th driving lever 2 indicating on the push rod 1 of numeral " 8 " onto push rod 1 below, all the other driving levers 2 on this push rod 1 are shifted push rod 1 top onto; Driving lever 2 on all the other push rods 1 is all shifted push rod 1 top onto, and so far password setting steps finishes, and the password arranging by above-mentioned steps is " 7435983 ".
While unblanking, suppose that password is set to " 7435983 ", if what button was pressed for the first time is while indicating the push rod 1 of numeral " 7 ", the briquetting 28 that first driving lever 2 on push rod 1 promotes on lower shifting board 10, briquetting 28 drives lower shifting board 10 to move, the position that lower shifting board 10 arrives between first pellet and second pellet, the like, often by moving the position of a pellet to a password lower shifting board 10, until six passwords are all by right, lower shifting board 10 has been crossed six pellets 18 successively, the briquetting 21 of lower shifting board 10 is depressed by the pressing plate of return driving lever 7, locking bar 12 is encountered through the groove that runs through of return driving lever in the outside of lower shifting board 10, locking bar 12 rotates along bearing pin 13, locking bar 12 exits from " recessed " shape groove of tooth bar 15, spring 14 ejects tooth bar 15, tooth bar 15 and gear 16 engagements, gear 16 is connected with door handle, swing handle, can complete unlocking action, if what button was pressed for the first time is not while indicating the push rod 1 of numeral " 7 ", due to the whole position in push rod 1 top of first driving lever that indicates other digital push rod 1, these driving levers 2 can promote the advance position of a pellet of upper mobile 3 plates, push the wrong password and all can promote a movable plate with push rod 1 when to password and move, so push the wrong password with identical by the feel to password.Because ball grooves 24 is interior, by ball 11, filled, only allow a spacing mandril 25 to enter ball grooves 23, so can not press two or more push rods 1 simultaneously.
While locking a door, first promote swing handle, make gear 16 band carry-over bar 15 returns, then press return driving lever 7 and tooth bar return device 26 simultaneously, tooth bar 15, upper shifting board 3 and lower shifting board 10 are resetted, can complete the action of locking a door.
