Description
Technical field
The present invention relates to a kind of mechanical code lock.
Background technology
The encrypted message that the insecurity of mechanical lock mainly comes from mechanical lock belongs to physical characteristic, and the encrypted message part that existing nearly all mechanical lock designs all can be surveyed, and causes safety and does not ensure.
Common safe-guard door lock adopts the cross lock core sheet, and pellet shot from a slingshot is exposed in the hole, adopts straightforward procedure promptly detectable; The dial-type coded lock that strongbox is used adopts multistage draw-in groove pattern, and aligning back locking bar can move and bring the most tangible physical features is sound, thereby lets the lawless person have an opportunity to take advantage of, and easily utilizes this characteristic to accomplish password cracking; Also have the importation of mechanical code lock to be exposed to the outside, enrolled encrypted message by the high power camera easily; More there is being very the ray scanning of employing structure reach the purpose of spying on; Crack method emerges in an endless stream, and does not break through the safety that will be difficult to ensure lock theoretically; So any mechanical lock can not be stressed the password complexity simply, password combination is many again, as long as detectablely will become meaningless.
The safety of mechanical lock should be assessed by password complexity and detectable degree two aspects, and the existing mechanical lock is not exactly paid attention to detectable degree this respect, and cracking of lock has more greatly in this link.Compare with electronic lock, electronic lock has innate advantage on detectable degree, and mechanical lock possesses innate advantage on stability.
The characteristic electron of electronic lock makes the rigid requirement in each national capital add emergency opening mechanism; And most of electronic locks are that emergency opening mechanism causes the safety factor of electronic lock to be reduced to standard machinery lock grade to increase common mechanical lock all; It is to adopt the dial-type mechanical code lock as emergency opening mechanism that part is also arranged; But dial-type mechanical code lock safe class own is not high yet; Password is detectable, wants to overcome the mechanical lock safety problem and but be unable to do without mechanical lock and limited deeply thereby cause electronic lock to get into development vicious circle-electronic lock.
And the mechanical code lock of developing a kind of safe enough all is instant to the development of electronic lock and mechanical lock own.Since but most of people thinks had safe mechanical code lock just need not add electronic lock again, electronic lock not only has superiority than mechanical lock in security fields in fact, and all there is the necessity of its existence aspect such as easy to use, Remote.Application number is that 02135963.6 Chinese patent discloses a kind of mechanical thumbwheel puzzle lock; Include multi-disc ring-type combination disk, chassis, lock bolt, bolt-operating mechanism, detent mechanism, dial-up mechanism, resetting-mechanism and spy ink recorder structure, shell and dial; Dial-up mechanism includes structural frame, dial-up piece, control device, and structural frame is a cylindrical shape, on cylinder, has the groove of placing the dial-up piece; Be provided with protruding tongue at cylinder one end; Control device includes sleeve, ratchet, control panel, and resetting-mechanism includes the brush that resets, spring and support, visits the ink recorder structure and includes control strip, positive stop lug boss, little axle and spring; Control strip is contained on the chassis through little axle, and the control strip front end contacts with ring-type combination disk outer rim.Though this lock has effectively increased number of password to a certain extent, and mechanical lock and coded lock are combined, it is detectable that password remains.
Summary of the invention
The present invention is directed to the detectable deficiency of password in the existing machinery lock, provide a kind of the password importation is partly separated with encrypted message, the mechanical code lock that engages when after the password input is accomplished, opening; The password importation is adopted individual palpation knob varying cyclically cipher wheel and deep hole observation pin mode to reach prevention and is spied on, and simultaneously isolated materials such as inner message part employing ray is prevented the overall plan of electromagnetic wave detection.
In order to solve the problems of the technologies described above, the present invention is able to solve through following technical proposals:
A kind of mechanical code lock comprises shell and cipher wheel, shell be provided with input unit with release the button, shell with input unit, releasing the button is connected respectively, described releasing the button is provided with the stop connecting rod.
As preferably, described input unit is input button or input knob or input rotating disc.
As preferably; Described input button or input knob are provided with fifth wheel; The input button comprises button and spring, and the input knob comprises knob and spring, and spring is located between the clamping plate and shell parallel with shell; And spring is fixed on button or the knob, and the end of button or knob links to each other with fifth wheel.
As preferably, digital calibration and stop slot are arranged on the described input rotating disc.
As preferably, described releasing the button is provided with moving latch lever, release the button with moving latch lever, stop connecting rod between be articulated and connected respectively or drive link is connected, cipher wheel is provided with groove, described moving latch lever and groove fit.
As preferably, described cipher wheel is provided with and shows wheel, cipher wheel with show between the wheel through bearing be connected, gears engaged, belt transmission or hinge connection.
As preferably, described cipher wheel is provided with password and revises wheel, and password is revised wheel and is provided with and shows wheel, and cipher wheel is revised between the wheel with password, password is connected through gears engaged, belt transmission or hinge between revising wheel and demonstration being taken turns.
As preferably, described shell is provided with peephole, described peephole with show that wheel is corresponding, be provided with organic glass outside the peephole, organic glass is fixedly connected with shell.
As preferably, described outer casing inner wall is provided with separation layer, and separation layer is fixedly connected with shell.
As preferably, described releasing the button comprises button and spring, or knob and spring.
Beneficial effect of the present invention comprises:
1, partly separate with encrypted message the password importation; The stop connecting rod of establishing on utilization is released the button separates input unit with cipher wheel, when password is imported, do not carry out the password comparison; Can not input password during the password comparison, really reach the purpose that password can't be spied upon.
2, the advantage separately that effectively combines mechanical lock and electronic lock lets the level of security breakthrough prior art of lock reach a new step.
Though 3, the setting of peephole simply but can further effectively prevent to be spied upon.
4, the separation layer of establishing on the outer casing inner wall prevents that effectively non-destruction penetration such as ray, electromagnetic wave from surveying internal construction and obtaining encrypted message.
5, a kind of mechanical code lock of the present invention has extraordinary application prospect at the aspects such as emergency opening mechanism of mechanical coded lock device and electronic lock.
