Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
The mechanical cipher device that a kind of one side is adjustable, comprise axle 1, housing 2, outer cipher wheel 24, password arrange switch, anti-back baffle plate 21, move back engage switch 3, reset switch 20, interior cipher wheel 25, axle move switch 26, described axle 1 has linear groove 19 vertically, and annulate shaft body has annular groove (23); Outer cipher wheel 24 inside has the through hole of truncated conical shape vertically, and this round platform through hole is coaxial with outer cipher wheel 24, and be processed with gear teeth along round platform generatrix direction in round platform through hole, two bottom surfaces of outer cipher wheel 24 form two ring surfaces; Interior cipher wheel 25 is sleeve-shaped, and the termination external surface of its one end is processed as truncated conical shape, and the generatrix direction along round platform is processed with gear teeth and is meshed with the gear teeth of outer cipher wheel 24, and the inwall of sleeve is provided with projection 22; The termination corresponding with the socket end of interior cipher wheel of axle 1 is that axle A holds, and the termination corresponding with the gear end of interior cipher wheel is that axle B holds; Outer cipher wheel 24 is limited in housing 2; Interior cipher wheel 25 is sleeved on axle 1 successively and the socket end direction of interior cipher wheel 25 is identical; The projection 22 of interior cipher wheel 25 can slide at the linear groove 19 of axle 1, when the projection 22 of interior cipher wheel 25 is positioned at annular groove (23) of axle 1, and the gear teeth engagement of inside and outside cipher wheel 24,25; Move back engage switch 3 hold with near axle A in the sleeve of cipher wheel 25 be connected, move back the socket end that engage switch 3 can promote interior cipher wheel 25, make the gear of inside and outside cipher wheel 24,25 exit engagement; Anti-back baffle plate 21 is positioned at axle B and holds, arrange switch with the password be arranged on housing 2 to be connected, anti-back baffle plate 21 is against when putting down near the termination of cipher wheel 25 gear end in B end, prevents the projection 22 of the interior password linear groove 19 of taking turns along axle 1 from moving and causes the gear of inside and outside cipher wheel 24,25 to exit engagement; Reset switch 20 is arranged on to be held on corresponding housing 2 with axle B, and the gear end that reset switch 20 can promote interior cipher wheel 25 makes it the gears meshing with outer cipher wheel 24; Axle moves switch 26 and is arranged on housing 2, and when the projection 22 of all interior cipher wheel 25 is all positioned at tram, axle moves switch 26 and axle 1 can be pulled to make it move vertically, thus realizes the conversion of encryption apparatus locking, unlatching; It is characterized in that: also comprise password scale dish, steering mechanism, described password scale dish is connected with steering mechanism, when password scale dish rotates, steering mechanism moves thereupon, steering mechanism contacts with outer cipher wheel 24, and under the drive of password scale dish, control the rotation of outer cipher wheel 24, because inside and outside cipher wheel has gear teeth to engage, within cipher wheel rotate with the rotation of corresponding password scale dish.
When this encryption apparatus is in the transformation of locking and opening, inside and outside cipher wheel is in engagement all the time, when password scale dish is positioned at correct password position, the projection 22 of its corresponding interior cipher wheel 25 is positioned at the annular groove of axle and the intersection of linear groove, when all password scale dishes are all positioned at correct password position, the conversion that switch 26 realizes encryption apparatus locking and unlatching can be moved by impeller-hub.When needs have carried out arranging of password, all password scale dishes are needed all to be positioned at correct password position, now open password and switch is set, then anti-back baffle plate 21 lifts, move back the socket end that engage switch 3 promotes interior cipher wheel, the projection of interior cipher wheel is slided along the linear groove 19 of axle 1, exit the engagement with outer cipher wheel 24, now rotate the password scale dish corresponding from different interior cipher wheel respectively, all password scale dishes are made to arrive new password position, now promote reset switch 20, in making, outer cipher wheel engages again, close password and switch is set, the anti-back baffle plate 21 then arranging switch control rule by password puts down, new password is provided with.
For the method decryption device preventing lawless person from adopting listening, be vacant state when the projection 22 of cipher wheel 25 slides in the linear groove 19 of axle 1 and annular groove (23) in the present invention, namely the linear groove 19 of axle 1 and annular groove (23) width and the degree of depth are greater than the height and width of projection 22.
Above-mentioned encryption apparatus can be set to one group, namely has one group of inside and outside cipher wheel, and described password scale dish only has level password dial 9, and level password dial 9 is arranged on housing 2; This device also comprises break-in axle 16 and change gear 18, and described break-in axle 16 one end is positioned at the center mounting hole 27 of level password dial 9, realizes the interlock with level password dial 9; The other end is fixed with change gear 18, and the lateral surface of change gear 18 is processed with gear teeth; The ring surface of described outer cipher wheel 24 is processed with the gear teeth in diametrically line direction; Gear teeth on the gear teeth of change gear 18 and outer cipher wheel 24 anchor ring matches, and can engage.When rotation level password dial 9, break-in axle 16 is driven to rotate, the change gear 18 of break-in axle 16 end rotates, the outer cipher wheel 24 be then meshed with change gear 18 is rotated, again because the internal gear of outer cipher wheel 24 is meshed with interior cipher wheel 25, outer cipher wheel 24 drives interior cipher wheel 25 to sway, the projection 22 of interior cipher wheel 25 socket end rotates along the annular groove (23) of axle 1, when the password of password scale dish is in tram, the projection 22 of interior cipher wheel 25 is positioned at the annular groove (23) of axle 1 and the intersection of linear groove 19, axle is now pulled to move switch 26, realize encryption apparatus locking, the conversion of opening.
For making the security performance of encryption apparatus better, this device comprises two groups of inside and outside cipher wheel, then corresponding password scale dish also comprises secondary password dial 8; Also comprise secondary break-in sleeve 7, secondary swing pinion 14, secondary transmission gear 15, secondary drive shaft 13, secondary change gear 17; Described secondary password dial 8 is arranged on housing 2, and level password dial 9 is arranged on above secondary password dial 8, and I and II password scale dish 8 is concentric; Secondary break-in sleeve 7 is sleeved on outside break-in axle 16, and the center mounting hole 27 that one end is positioned at secondary password dial 8 realizes the interlock with secondary password dial 8; The end of the other end is fixed with secondary swing pinion 14; Secondary drive shaft 13 axle is installed with secondary transmission gear 15, this secondary transmission gear 15 is meshed with secondary swing pinion 14, secondary change gear 17 is fixedly mounted on the end of secondary drive shaft 13, and be meshed with the gear teeth on the anchor ring of corresponding outer cipher wheel 24, the other end of secondary drive shaft 13 to be arranged on housing 2 and can to rotate relative to housing 2.When rotation secondary password dial 8, the secondary break-in sleeve 7 then linked with it rotates, the secondary swing pinion 14 be fixedly mounted on secondary break-in sleeve 7 rotarily drives the secondary transmission gear 15 engaged with it and rotates, because secondary transmission gear 15 is fixedly mounted in secondary drive shaft 13, then secondary drive shaft 13 is rotated thereupon, drives secondary change gear 17 to rotate; Secondary change gear 17 drives second group of outer cipher wheel 24 to rotate, and in outer cipher wheel 24 is driven by inner gear teeth again, cipher wheel 25 rotates around axle 1.
