Abstract
The utility model discloses a mechanically-working coded lock which comprises a lock casing and a lock cover matching the lock casing. The lock casing is provided with a locking dog which is positioned in the inside and works with the lock cylinder via a transmission connecting rod. The transmission connecting rod is provided with a torsion spring which makes the transmission connecting rod closely contacted to the lock cylinder. The mechanically-working coded lock further includes a lock-up structure which comprises a screw rod fixed on the lock casing. The screw rod is provided with a spring and a limit spacer. The limit spacer, with the assistance of the lock cover, keeps the spring in a compressed state and a limit groove which matches the limit spacer is disposed on the lock dog. The introduction of such a lock-up structure enables the limit spacer to act with the spring and to move along the screw rod towards the limit groove on the lock dog when the key core and the lock cover are damaged in a locked state of the mechanically-working coded lock. Further, influenced by the working of the limit groove on the lock dog, the limit spacer shall not contract, therefore, causing a phenomenon that the mechanically-working coded lock cannot be opened even when the key core is damaged. With the introduction of such a mechanically-working coded lock, the security and safety of a safe shall be greatly improved.

Reach technique effect in order to further specify the utility model mechanical code lock, 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 cooperates fixing with strongbox or safety cabinet.
When described coded lock by outside destroy lock core 1 ' after, described locking closure 2 drops easily, because described locking closure 2 makes described spring 11 maintenance compressive states by banking stop when cooperating fixedly with lock housing 1.Under the effect of spring 11, make described banking stop 10 move to stopper slot 31 along described screw rod 12, add in the lock 1 thereby make described dead bolt 3 to receive, use the strongbox of this coded lock or safety cabinet to open.
Owing to be provided with locking structure, when mechanical code lock is in the lock state, destroy described banking stop behind lock core and the locking closure and move to stopper slot on the dead bolt at the effect lower edge of spring 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, first toothed disc 7 and the clutch 6, makes described first toothed disc 7 and second toothed disc 9 separate.The angle of rotating when described driving wheel 5 hour, described first toothed disc 7 and second toothed disc 9 are separate, can not drive 9 rotations of second toothed disc because of 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 first toothed disc 7 and rotate, and cooperates 8 rotations of fixing adjustment disk simultaneously with first toothed disc 7; 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 first toothed disc 7 be arranged on second toothed disc 9 on cannelure 73 in clutch 6 on moving part 61 cooperates, make 9 rotations of described second toothed disc.
When the adjustment disk on two adjustment disks 8 opens 81 during at same straight line, and open one's mouth 52 angle position of rising on the described driving wheel 5 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, it is fixing to make that two fixed teeth 82 break away from first toothed disc 7 and second toothed disc 9, to rotate again with starting and open 5 fixing rotating disks, take out special tool, described fixed teeth 82 cooperates fixing again with tooth on first toothed disc 7 and second toothed disc 9, obtain new password; Because adjustment disk opening 81 on the described adjustment disk 8 and the angle between the peristome 74 on first toothed disc 7 and second toothed disc 9 change, the angle that reason is rotated is also inequality.
In the foregoing description, the quantity of described first toothed disc 7 can be provided with one, two or more as required, and two first toothed discs 7 are adjacent, and is corresponding with it with the quantity of fixing adjustment disk 8 of first toothed disc 7 and clutch 6.Tooth is many more on described first toothed disc 7 and second toothed disc 9, and then the number of password of described coded lock is also big more; The quantity of described first toothed disc 7 is many more, and then the number of password of coded lock is also just many more.
For example, when described first toothed disc 7 was one, during 100 teeth on described first toothed disc 7 and second toothed disc 9, number of password was 100 * 100; When described first toothed disc 7 was two, during 100 teeth on described first toothed disc 7 and second toothed disc 9, number of password was 100 * 100 * 100.
When the tooth on described first toothed disc 7 and second toothed disc 9 was 150, the number of password of one first toothed disc 7 and 9 combinations of second toothed disc was 150 * 150; In like manner the number of password of two first toothed discs 7 and 9 combinations of second toothed disc is 150 * 150 * 150.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model manual and accompanying drawing content to be done; 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 utility model.
