Specifically, described kinematic link 4 one ends are respectively equipped with holding section 41 and limiting section 42, and wherein, described holding section 41 cooperates with starting port 52 on the driving wheel 5, described limiting section 42 cooperate with adjustment disk opening 81 carry out spacing.
Such as Fig. 4 a, Fig. 4 b, Fig. 5, Fig. 6 and shown in Figure 7, the driving wheel 5 of the coaxial connection of described lock core 1 ' comprise, clutch 6 and the password adjustment structure corresponding with clutch 6, described driving wheel 5 and clutch 6 and password adjustment structure are set on the hollow circuit cylinder 15 on the lock housing 1 in order; Described password adjustment structure comprises the first toothed disc 7 and the second toothed disc 9, wherein, the first toothed disc 7 is fixed with adjustment disk 8, these the first toothed disc 7 one sides are provided with the cannelure 73 that cooperates with clutch 6, this cannelure 73 is provided with peristome 74, take in the linkage part 61 on the clutch 6 in this peristome 74,61 spacing cooperations of linkage part on the boss 51 on the described driving wheel 5 and the clutch 6, the opposite side of described the first toothed disc 7 is provided with the protuberance 71 that cooperates with linkage part 61; The second toothed disc 9 is fixed with another adjustment disk 8, these the second toothed disc 9 one sides are provided with the cannelure 73 that cooperates with clutch 6, this cannelure 73 is provided with peristome 74, take in the linkage part 61 on the clutch 6 in this peristome 74,61 spacing cooperations of linkage part on the boss 51 on the described driving wheel 5 and the clutch 6.
The adjustment disk opening 81 that described adjustment disk 8 is provided with centre bore 85 and cooperates with kinematic link 4, be provided with two fixed teeth 82 that cooperate with the first toothed disc 7 and the second toothed disc 9 at these centre bore 85 inwalls, be provided with arcuate socket 84 in two fixed teeth, 82 1 sides, and this arcuate socket 84 is connected with centre bore 85 and forms positioning section 83.When described the first toothed disc 7 and the second toothed disc 9 cooperate with adjustment disk 8, be fixed by the tooth 72 on fixed teeth 82 and two toothed discs.Described adjustment disk opening 81 can be made as trapezoidal or other shapes as required.
Reach technique effect in order to further specify mechanical code lock of the present invention, specify the tool course of work:
When described mechanical code lock was in off status, described dead bolt 3 was in the state of stretching, the stopper slot 31 on this dead bolt 3 be in banking stop 10 directly over, the part that described dead bolt 3 stretches out lock housing 1 is fixed with strongbox or safety cabinet.
When described coded lock by outside destroy lock core 1 ' after, described locking closure 2 easily drops, because described locking closure 2 makes described spring 11 keep compressive states by banking stop when being fixed with lock housing 1.Under the effect of spring 11 so that described banking stop 10 moves to stopper slot 31 along described screw rod 12, thereby so that described dead bolt 3 can't receive add to the lock 1 in, use the strongbox of this coded lock or safety cabinet to open.
Owing to being provided with locking structure, when mechanical code lock is in lock status, destroy described banking stop behind lock core and the locking closure and under the effect of spring, move to stopper slot on the dead bolt along screw rod, this dead bolt is under the effect of stopper slot, can't shrink, thereby the mechanical code lock that can after the lock core of coded lock is destroyed, can not open, improve the safety cabinet of this coded lock of use or the safety of strongbox.
Described by rotate with lock core 1 ' on the fixing rotating disc of driving wheel 5, the boss 51 on the described driving wheel 5 makes described clutch 6 rotations under linkage part 61 cooperates.Between the hollow circuit cylinder 15 on described driving wheel 5 and the lock housing 1, be provided with sleeve; Be provided with guide groove 13 in the outside of described hollow circuit cylinder 15, this guide groove 13 cooperates with setting-up piece 14, and this setting-up piece 14 is arranged between driving wheel 5 and clutch 6, the first toothed disc 7 and the clutch 6, makes described the first toothed disc 7 and the second toothed disc 9 separate.The angle of rotating when described driving wheel 5 hour, described the first toothed disc 7 and the second toothed disc 9 are separate, can not drive 9 rotations of the second toothed disc because the first toothed disc 7 rotates; The angle of rotating when driving wheel 5 is greater than clutch 6 during in the angle that described peristome 74 moves, boss 51 on the described driving wheel 5 cooperates with linkage part 61 on the described clutch 6 and drives described the first toothed disc 7 and rotate, and the adjustment disk 8 that is fixed with the first toothed disc 7 simultaneously rotates; The angle of rotating when described driving wheel 5 is greater than clutch 6 during in the angle that described peristome 74 moves, protuberance 71 on described the first toothed disc 7 be arranged on the second toothed disc 9 on cannelure 73 in clutch 6 on moving part 61 cooperates, make 9 rotations of described the second toothed disc.
When the adjustment disk on two adjustment disks 8 opens 81 during at same straight line, and the angle position of the starting port on the described driving wheel 5 52 cooperates with holding section 41 and limiting section 42 on the kinematic link 4, thereby can make described dead bolt 3 stretch out or shrink.
When needs change password, cooperate with adjusting portion 83 on the adjustment disk 8 by the patent instrument, so that breaking away from the first toothed disc 7 and the second toothed disc 9, two fixed teeth 82 fix, to rotate again with starting and open 5 fixing rotating disks, take out special tool, described fixed teeth 82 again with the first toothed disc 7 and the second toothed disc 9 on tooth be fixed, obtain new password; Because the adjustment disk opening 81 on the described adjustment disk 8 and the angle between the peristome 74 on the first toothed disc 7 and the second toothed disc 9 change, the angle that reason is rotated is not identical yet.
In above-described embodiment, the quantity of described the first toothed disc 7 can arrange one, two or more as required, and two the first toothed discs 7 are adjacent, and is corresponding with it with the quantity of the fixing adjustment disk 8 of the first toothed disc 7 and clutch 6.Tooth is more on described the first toothed disc 7 and the second toothed disc 9, and then the number of password of described coded lock is also larger; The quantity of described the first toothed disc 7 is more, and then the number of password of coded lock is also just more.
For example, when described the first toothed disc 7 was one, during 100 teeth on described the first toothed disc 7 and the second toothed disc 9, number of password was 100 * 100; When described the first toothed disc 7 was two, during 100 teeth on described the first toothed disc 7 and the second toothed disc 9, number of password was 100 * 100 * 100.
When the tooth on described the first toothed disc 7 and the second toothed disc 9 was 150, the number of password of first toothed disc 7 and 9 combinations of the second toothed disc was 150 * 150; In like manner the number of password of two the first toothed discs 7 and 9 combinations of the second toothed disc is 150 * 150 * 150.
The above only is the preferred embodiments of the present invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes manual of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
