The operating principle of this detailed description of the invention is: first manually set password, then must correctly by the sequence of coden input set in the process of unblanking, and just can unblank, Password Input mistake or order input error, all can not complete and unblank.

One, password is set:

1.1, first password is set.First in the often row of matrix, password setting button 113 is inserted, engage with the fixed gear 12 of correspondence position and belt 112, wherein 113, the password setting button of the first row and the upper gap-contact of one of them fixed gear 12, the password setting button 113 of last column only with the lower gap-contact of one of them fixed gear 12, other password setting buttons 113 respectively with the gap-contact up and down of fixed gear 12, such as matrix is arranged as 4x4, the position that password setting button 113 inserts as shown in Figure 5: be 2324 as schemed corresponding password.

1.2, position-limit mechanism is adjusted.Original state key activities plate 46 is unlocked states, now key activities plate 46 can move up and down, then according to the number of times that the numeral of each button 41 correspondence occurs in the password of setting, rotate each button 41 concavo-convex axle position-limit mechanism 49 below, in such as Fig. 5, password is 2324, rotate second button 41 concavo-convex axle position-limit mechanism below 49 2 times, rotate the 3rd button 41 concavo-convex axle position-limit mechanism 49 below once, rotate the 4th button 41 concavo-convex axle position-limit mechanism 49 below once, the position of now corresponding each main shaft 44 is moved, key activities plate 46 is locked.

Two, to unblank step:

2.1, the operating principle of password setting dish 1 in process of unblanking:

2.1.1, Password Input is correct: when inputting first correct password, the tooth axle 11 that corresponding dynamic cingulum 10 drives the first row to insert password setting button 113 rotates, password setting button 113 all engages with belt 112 and fixed gear 12, so belt 112 is driven to rotate, the tooth axle 11 that second row inserts password setting button 113 is driven to rotate, in rotary course, fixed gear 12 is below height grooves, when forwarding high groove to, the tooth axle 11 of the second row is by check key, move right, contact with corresponding dynamic cingulum 10, simultaneously block body 17 promotion connection lever 18 makes portable plate 9 move down, in the process that block 13 simultaneously on the left of second tooth axle 11 moves right, lever 14 is driven to rotate, return plate 15 is moved to the left from lever 14 upper end simultaneously, spring 16 does not work, now deputy Password Input correct after, the tooth axle 11 that corresponding dynamic cingulum 10 drives the second row to insert password setting button 113 rotates, the 3rd tooth axle 11 is driven to rotate by belt 112, by that analogy, each tooth axle 11 is close to while dynamic cingulum 10, capital drives small lever 110-1 wherein that a tooth axle 11 is playbacked, reseting baffle 111 and manual returning device 6 and doorframe automatic resetting device 7 of closing the door is connected, by closing the door or manually playbacking by force, now the tooth axle 11 of the first row drives big lever 110-2 that last tooth axle 11 is playbacked while being playbacked, until all passwords input correctly all in order, portable plate 9 all completes at every turn and moves down, thus coordinate password key mechanism 4 to complete and unblank.

2.1.2, Password Input mistake: wherein any Password Input mistake, portable plate 9 can not move down, and can not coordinate with password key mechanism 4, unblanks to carry out, needs rotation manual returning device 6, again input password in order.

2.2, the operating principle of device sound mixing 2 in process of unblanking: device sound mixing 2 is that two row are arranged, two that often arrange time initial detachable tooth axles 21 all have one to engage with dynamic cingulum 10, the detachable tooth axle 21 that each and dynamic cingulum 10 engages can be separated by moving up and down of portable plate 9, has dismountable projection 9-1 part in the hole of portable plate 9 as shown in Figure 7.

2.2.1, Password Input correct time: the detachable tooth axle 21 engaged with dynamic cingulum 10 rotates, but now portable plate 9 moves down, and is cut off by detachable tooth axle 21, and the detachable tooth axle 21 of another one does not move, process of unblanking continue.

2.2.2, during Password Input mistake: the detachable tooth axle 21 engaged with dynamic cingulum 10 rotates, now portable plate 9 is motionless, audio mixing belt 212 drives next detachable tooth axle 21 to rotate, detachable tooth axle 21 is the same with tooth axle 11 principle of password setting dish 1, move right close to dynamic cingulum 10, simultaneously by detachable tooth axle 21 return that the small lever of audio mixing return leverage 210 will engage with dynamic cingulum 10 originally, and be driven the detachable tooth axle 21 moved right and engage with dynamic cingulum 10, now it can be separated by moving up and down of portable plate 9, be disassembled when waiting for that Password Input is correct next time.There is Flexible change and sound, in case stop-pass crosses sound decryption in the audio mixing spring 26 in this process.Audio mixing reseting baffle 211 structure is the same with reseting baffle 111 principle of password setting dish 1 is all by lever principle, returns to original state to make each detachable tooth axle 21 of device sound mixing 2.

2.3, the operating principle of password key mechanism 4 in process of unblanking: the corresponding password key mechanism 4 in below of each dynamic cingulum 10, mean corresponding one or more correct password, each button press 41, capital drives corresponding dynamic cingulum 10 to move, in this embodiment, the structure of button 41 adopts the button of ball pen type, there are front rotating part and rear rotating part and spring, the part of rotating before pressing, after driving, rotating part rotates thus to dynamic cingulum 10 active force of engagement, then passes through spring return function.

2.3.1, when Password Input is correct: portable plate 9 moves down, the movable part 45-2 of postive stop baffle 45 is lifted, now the first clamping plate 42 coordinate the second clamping plate 43 to clamp main shaft 44 by gradient to the right to move right a fixing distance, main shaft 44 drives countershaft 48 to the right, make limit part mobile position on concavo-convex axle position-limit mechanism 49, when all passwords are all pressed right time, concavo-convex axle position-limit mechanism 49 revert to password arrange before state, now key activities plate 46 is unlocked state, mobilizable key activities plate 46 can coordinate with opening mechanism of lock spring bolt 5 unblanks.

2.3.2, during Password Input mistake: the movable part 45-2 of postive stop baffle 45 does not lift, button 41 is stoped by movable part 45-2 clamping main shaft 44 mobile trend to the right, the standing part 45-1 of postive stop baffle 45 moves right, key activities plate 46 is locked further, key activities plate 46 is in locking state, can not coordinate unblank with opening mechanism of lock spring bolt 5.

2.3.3 the returning device principle, in password key mechanism: wherein return lever 412 and manual returning device 6 and doorframe automatic resetting device 7 of closing the door is connected, after startup resets, return button 410 is by the arm spring 411 of lever pushing audio mixing reseting baffle 211, thus completing the reset of device sound mixing 2, concavo-convex axle position-limit mechanism return button 413 is by each concavo-convex axle position-limit mechanism 49 return.

2.4, the operating principle of opening mechanism of lock spring bolt 5 in process of unblanking:

2.4.1, Password Input correct time: press main shaft 51 of unblanking, unlock lever 56 promotes key activities plate 46 and moves up, and countershaft 52 of unblanking moves, and pressure handle 53 opening, presses pressure handle 53, and drive dead bolt axle 54, unlock deadbolt 55, completes and unblank.

2.4.2, during Password Input mistake: key activities plate 46 is locking state, and main shaft 51 of unblanking, by motionless, can not complete and unblank.

Mechanical code lock of the present utility model, the mechanical process of unblanking is all linked with one another, and anti-theft feature is high, but operation is very easy.

The exemplary illustration of present embodiment just to this patent, does not limit its protection domain, and those skilled in the art can also change, as long as no the Spirit Essence exceeding this patent, in the protection domain of this patent its local.
