Open Cipher safe

The utility model provides a kind of public coded safe case, it belongs to daily hardware technology field, be applicable to that bank, office, factory, army, shop, family deposit huge cash, important bill, classified papers and valuables make to change the security door that also can become important place slightly.

The thinking of public-key cryptography sign indicating number is of long duration, and does not see substantial breakthrough so far but be applied to safety cabinet.Publish in March, 1986 by Ke Zhao according to Higher Education Publishing House, the chapters and sections medium cloud of " mathematics teaching materials (on) " book " trap door onr way function and public-key cryptography sign indicating number " that Sun Qi writes: " public-key cryptography sign indicating number system is based on the trap door onr way function that enlightening expense (Diffie) in 1976 and Hellman (Hellman) propose; Li Fansite (Rivest) trap door onr way function of at first finding a class to be convenient to use in 1977; claim the RSA system usually; theorem: establish m=pq and suitably select two given odd prime pq; and the satisfied (S; P-1)=(S of positive integer, q-1)=1, calculate given formula and only need several seconds time with electronic computer "; add in the book: " from m, decomposite given pq two odd primes, but need to spend many surprising times, can be described as and to realize "." public coded safe case " that the U.S. is developed according to the RSA system is with one of the m(number of 100 multidigits nearly) be marked on the safety cabinet, and the practical operation password is two big odd primes of pq() " this " public coded safe case " actual to sign indicating number action be still can not be disclosed.This safety cabinet of U.S.'s development can reflect the yearning of safety cabinet manufacturing industry to public coded safe case from a side, acoustic control safety cabinet, magnetic card key safety cabinet, Fingerprint Lock safety cabinet etc. all belong to symbolistic " public coded safe case ", they also respectively have weak points: in imitative audio technology flourishing day by day today, the safety factor of acoustic control safety cabinet decreases; The magnetic card key as a kind of existence of object have again be stolen may, use fingerprint after can making cabinet master obnubilation to Fingerprint Lock safety cabinet offender.The technology that Zhejiang modern microelectric technique Development Co., Ltd is had: computer cipher safe, can establish 6 figure place passwords arbitrarily by the user, it is strong that computer technology is applied to the safety cabinet sense of the times, but the input code signal moves still to avoid surreptitiously and looks when opening the cabinet door, deadly defect there is no in response to eliminating with new and high technology, 12 kinds of the different electronic locks of domestic and international function have been enumerated in " electronic lock general view " literary composition of 1992 the 7th phases " radio " Li Wenshi, can be applied to have nine kinds of safety cabinet, all not possess the function that unlocking action is open and don't divulge a secret.It is blank to find out also that from " search report " of Fujian Institute of Scientific and Technical Information public coded safe case worthy of the name still belongs at present.By consulting Patent data, the patent No. be CN86100207A's " being used in two new equipments on ' miser ' board safety cabinet ", this invention has an automatically rebounding open wicket of energy, with the main handle that is exposed on the gate, combination disk, lock are fully hidden, but whole actions of opening the cabinet door are as if stolen looking, and acquisition key or duplicate, and wicket and gate all will be opened smoothly.Surreptitiously do not look this deadly defect owing to fundamentally solve sign indicating number action avoided most, so the stolen incident of safety cabinet internal memory thing takes place repeatedly still.In the market the different safety cabinet of supplying functional except to sign indicating number action avoid most surreptitiously look, also have following four drawbacks: (1) based on the safety cabinet of frame for movement its to the sign indicating number action all need by light source; (2) the external damage maloperation certainly will damage inner body (the said outside destroy of standing of present safety cabinet is all protected with the soundness of its cabinet and the disguise of exterior part); (3) easily visited sign indicating number based on the safety cabinet of frame for movement by rocking main handle; (4) its warning system of low and middle-grade safety cabinets that has wide range of applications is easily by artificially out of control.

The purpose of this utility model is to develop a kind of safety cabinet with following five big characteristics: the overall process of (1) opening safety cabinet (comprising the sign indicating number action) is not avoided and is looked on; (2) under the situation of no any light source, also can carry out sign indicating number is moved; (3) maloperation of outside all tumblers does not all damage inner body; (4) do not avoid feel or audiometry and visit sign indicating number; (5) warning system is difficult to artificially out of control.

Solution of the present utility model and theing contents are as follows:

Solution: realize that to code system with to the sign indicating number induction structure sign indicating number dead-center position is had only owner's identification in operation alone with multiaxis system and double plate system, add scale wire casing on the dial 3 and the convex graticule on rotating disk 4 end faces based on above-mentioned characteristic, the graticule groove on the spindle nose face of cylinder has been formed no light source again to code system.Force rate relation (the former is less than the latter) with the active force during code-disc 11,12 actions before and after 21 pairs of the active linkage dial of diversification and the holding capacity of dial 21 active linkages realizes external damage maloperation inoperation inner body, does not avoid feel or audiometry and visits yard.With a kind ofly have maloperation, move, the circuit theory of isolation, shielding, short circuit, the central authorities' work of opening circuit that all making reports to the police and carry out forms the infra-red remote control warning system and carry out locational specially treated between signal transmits and receives, from putting to good use of space limit restriction means of destruction.

The particular content division is as follows:

1, owner's desire of safety cabinet is opened the cabinet door, at first key is inserted lock core 9 back rotations, make lock core 9 align with the graticule of lock 8 (Fig. 1), lock core off-centre 51 promptly goes to peak like this, hold up limit frame 53 by lifting backup plate 52, remove the bite (Fig. 6, Fig. 7) on clasp 48 and each code-disc 11,12 edge, front and back, at this moment just effective to sign indicating number.The utility model is owing to adopt eccentric, key not the recipient to restriction, and allow to rotate arbitrarily continuously, after the action of key is finished, be target then with the signal receiver hole on the cabinet door 10, K switch 31(Fig. 1 by the infra-red remote control transmitter in starting 101, Figure 13), make the finger sense in the cabinet produce circuit 102(Figure 14) NPN triode BG41(refer to feel first master switch that produces circuit 102) after the conducting, can carry out sign indicating number, footstalk 5 is all pushed away inward, a finger with left hand, by on feel contact 7, the right hand rotates footstalk 5, dial 21 in the cabinet is promptly rotated (Fig. 1 thereupon, Fig. 2), by B face dial pin 23(Figure 11) drive back code-disc 12(Fig. 2), as the conductor 54(Fig. 8 that is embedded on 14 of the insulating disc of back in the code-disc 12) refer to feel second master switch of generation circuit 102 with the K switch 41(that two contacts of back contact base 16 are formed) contact or when disconnecting, feel by the faint electric shock that the finger on feel contact 7 promptly has the wink sense promptly to die, at this moment be only place (Fig. 2 at zero point to sign indicating number, Figure 14, when Fig. 1), go to latent note owner in the heart reading for the beginning (idle running before surreptitiously do not look for fascination person) zero point thus sign indicating number is put in place.Inserted tooth 17 on the back code-disc 12 is aimed at jacking block 32(Fig. 2, Fig. 3).Then footstalk 5 is pulled outward, make the interior overlapping along the limit of toroid 25 and dial 3 on the spindle nose, at this moment dial 21 is in neutral gear, and footstalk 5 can arbitrarily rotate, and is mess code in the operation.Then footstalk 5 is pulled outward again, can carry out preceding code-disc 11 sign indicating number is moved (Fig. 2) no matter footstalk 5 pushes away inward or pulls outward after making spacing cake 27 be close to support plate 29, it only is being with dial 21 same moved further, and front and back code-disc 11, on 12 bearings 57 and sleeve 30 that are suspended from the code-disc location fork 20, do not produce friction with axle 26, front and back code-disc 11,12 meetings are at A face or B face dial pin 22, making circumference under 23 the drive rotates, and can be with the moving (Fig. 2 of axle 26 front and back string, Fig. 8, Fig. 9), and dial 21 should be made circumference with axle 26 and rotates to finish sign indicating number is moved, moving with axle 26 front and back string again, code-disc 11 before and after realizing, 12 to mess code in the operation of sign indicating number and middle neutral gear, the former is by spring 58 compressing steel balls 59 doff mortars, make 26 one-tenth active interlocks of dial 21 and axle, the interior edge of latter's closing slit bamboo or chopped wood centring ring 24 embeds in the annular groove of axle 26, so neither destroy above-mentioned activity interlock, can finish its action (Fig. 2 at three diverse locations with axle 26 again, Figure 10, Figure 11, Figure 12).Even therefore clasp 48 and 11,12 interlocks of front and back code-disc, rotating 5 of footstalks by force can make steel ball 59 compression springs 58 from the axle mortar, when A face or B face dial pin 22,23 and code-disc pin 13 hit unmoving axle 26 idle running (Fig. 7, Figure 10, Figure 11, Fig. 2) when meeting, as seen this does not partly have the external damage maloperation yet and damages the trouble and worry of inner body.Article three, before and after three couple on the axle 26 code-disc 11,12 after action is all finished to sign indicating number (Fig. 2, Fig. 3) pull main handle 6, big bearing 39 on the main handle off-centre 40 drives bearing frame 38 and moves to lock bolt 46 rightabouts along the guide rail that is fixed on the big track base 37 that exposes on the door-plate 2 from the square window 47 of latch board 28, at this moment bearing frame 38 is being with give up the throne groove jacking block 41 and spring frame 44 of band to move, because latch board 28 connects by pin 45 with spring frame 44, so latch board 28 also moves thereupon.(Fig. 4, Fig. 5) to sign indicating number action all accurately the time, each jacking block 32 that is fixed on six little track bases 31 on the latch board 28 heads on inserted tooth 17 compression little springs 56, inserted tooth pin 18 is gone inwards along the slotted hole of cover plate 19, (when not pulling main handle, inserted tooth 17 under the effect of little spring 56 to extrapolation, the positioning action of inserted tooth pin 18 and cover plate 19 slotted holes, make inserted tooth 17 and front and back code-disc 11, tooth alignment on 12 edges) jacking block 32 just gos deep into each front and back code-disc 11, in 12 the elongated slot, thereby make lock bolt 46 be achieved (Fig. 3 from mortar, as long as Fig. 8) otherwise have inserted tooth not in place and pull main handle 6, jacking block 32 withstands on preceding code-disc 11 or code-disc 12 edges, back, latch board 28 is motionless, at this moment be with the groove jacking block 41 compression big springs 43 of giving up the throne, spring frame 44 is motionless, and latch board 28 is also motionless, the cabinet door (Fig. 3 that do not open, Fig. 4, Fig. 5).Pull main handle 6 under the situation not in place to sign indicating number, bearing frame 38 also is being with in the same old way and is being with the groove jacking block 41 of giving up the throne to move, and compression big spring 43, and spring frame 44 local going deep into are with in the abdomen of the groove jacking block 41 of giving up the throne.Therefore main handle 6 also can be done 360 ° of rotations under the situation not in place to sign indicating number, and inoperation inner body, to the sign indicating number main handle 6 of pulling not in place, little track base 31 is code-disc 11 before and after each, 12 draw close, because jacking block 32 is withstood, force it to compress medi-spring 33 round about, touch the microswitch 35 that is fixed on the door-plate 2 by contact pin 34 and realize (the Fig. 5 that reports to the police, Fig. 3, Figure 16, Figure 17) owner gets thing and finishes, desire to close the cabinet door, can pull main handle 6, after being moved to right, lock bolt 46 closes the Over-The-Counter door, three diverse location (linings, in, rotate three footstalks respectively more than 5 one weeks outward), the rotation amplitude differs, because two dial pins 22 on A face and the B face, 23 respectively with irregular alignment, add the action of above-mentioned mess code after, very big difference just appears in the number of division to sign indicating number rotated next time, the stranger is utterly ignorant of again to the dead-center position in owner's operation, sign indicating number is not avoided the deadly defect of surreptitiously looking just obtain basic solution (Fig. 4, Fig. 5, Fig. 2, Figure 10, Figure 11).Get final product screw key after finishing the mess code action, in the time extracting key out, lock core off-centre 51 promptly is in minimum point, clasp 48 and each front and back code-disc 11,12 interlocks again, even clasp 48 is code-disc 11 before or after certain, 12 tooth top hits chance, as long as one rotate footstalk 5 slightly, because the effect of hinge 49 and extension spring 50, the front or rear therewith code-disc 11 of clasp 48, the just automatic interlock (Fig. 6 of 12 tooth, Fig. 7) key is as if being stolen or copying, the robber obtains to remove 48 pairs of each front and back code-discs 11 of clasp, 12 interlocking also can't realize visiting sign indicating number, although front and back code-disc 11,12 function increases, some parts have been added, weight also increases thereupon, but rotating still can be free and relaxed, with front and back code-disc 11, on 12 sleeves 30 and bearing 57 that are suspended from the code-disc location fork 20, do not produce friction with axle 26, so just reduced the action force that dial 21 is paid widely, if the desire row rocks main handle 6 and visits sign indicating number, code-disc 11 before and after jacking block 32 is promptly oppressed, 12, its resistance is greater than the regular event power of dial 21, at this moment rotate footstalk 5, steel ball 59 is a pressuring spring 58, front and back code-disc 11,12 is motionless, axle 26 idle running, code-disc 11 before and after if jacking block 32 falls into, in 12 the tooth paddy, institute effect occurs as mentioned above, therefore can't obtain each to front and back code-disc 11, the feel of 12 breach.Owing on the insulating disc 14 of front and back code-disc 11,12, be provided with anti-eavesdrop simulation line 55, simultaneously also audiometry less than special sound equipment (Fig. 8, Fig. 9, Fig. 3).

2, public coded safe case can carry out leaning on following special construction to realize to sign indicating number under the situation of no any light source: on rotating disk 4 end faces is the three-dimensional graticule that protrudes the plane to sign indicating number graticule (Fig. 1), back code-disc 12 sign indicating number is undertaken by this convex graticule cooperation dial 3, become also to have on 90 ° the spindle nose a recessed face of cylinder and 26 one-tenth parallel graticule grooves of axle with rotating disk 4 end faces, pulling out this graticule groove of spindle nose promptly appears, preceding code-disc 11 sign indicating number is undertaken by this graticule groove cooperation dial 3, owner's desire think closed to sign indicating number or between black night to sign indicating number, method is as follows: footstalk 5 is postponed rotation inward, obtaining feel promptly stops, scale wire casing on the dial 3 that is alignd with that convex graticule on the rotating disk 4 is a starting point, with an a spicule silent some password number on dial 3 single-frame, on the scale wire casing that puts in place, insert a tablet, and extend to rotating disk 4 central sides, become interim limiting plate, rotate footstalk 5 then, make the convex graticule on the rotating disk 4 touch chance with interim limiting plate, 12 pairs of sign indicating numbers of back code-disc are promptly accused and are finished, extraction footstalk 5 makes spacing cake 27 be close to support plate 29 can carry out preceding code-disc 11 sign indicating number is moved, obtain the footstalk 5 that stops operating after the feel as mentioned above, with an a spicule silent some password number on dial 3 single-frame, on the scale wire casing that puts in place, insert a tablet, and allow tablet touch the spindle nose face of cylinder, rotate footstalk 5, code-disc the sign indicating number action is also accused finished before when tablet falls into graticule groove on the spindle nose face of cylinder, other front and back code-disc 11 on 26,12 to sign indicating number by that analogy.

3, the public coded safe case circuit divides two parts:

(1) code checking sensing circuit

Owner's desire is opened the cabinet door after key puts in place, be target K switch 31(Figure 13 then by the infra-red remote control transmitter in starting 101 with signal receiver hole 10) promptly produce the black light that a high-frequency impulse is modulated, by one of IC 31 and peripheral cell R31R32W31C31 output is not high frequency voltage known to the stranger, promoting final stage BG31 makes the D31 infrared emission tube flow through high frequency pulse power supply, send a string high-frequency impulse infrared rays, the finger sense in the cabinet at this moment produces circuit 102(Figure 14) the first master switch NPN triode BG41 conducting.Refer to that it is to utilize the pulse boosting principle that sense produces circuit 102; produce a high voltage; and weak current; make the finger on the feel contact 7 that very weak electric shock sensation be arranged; reversal connections such as available 6.3V/220V indicator lamp transformer are elementary to be low-pressure side; secondary is the high-pressure side; K41 is actual to be conductor 54 and front and back contact base 15 on the insulating disc 14; the switch that two contacts on 16 are formed (just referring to feel second master switch that produces circuit 102) during to sign indicating number before or after code-disc 11; 12 conductors when turning to certain position 54 and front or rear contact base 15; two contacts on 16 hit chance (switch motion of the actual K41 of being) K41 closure; the moment that disconnects; just produce a pulse current by the transformer center common point that back one is connected to feel contact 7 that boosts; the other end is connected to six metal dots on this feel contact 7; be regardless of both positive and negative polarity; W42 is for regulating the potentiometer of output voltage; so that adapt to the eliminating dampness of Various Seasonal finger; D41 is the protection diode; so that the absorption negative pulse voltage does not cause transformer to puncture.The power supply switching of this circuit is subjected to infrared remote control receiver 103(Figure 15) control, just work after the NPN triode BG41 conducting otherwise do not work.The D51 that is installed in the infrared remote control receiver 103 in the cabinet is the special-purpose reception diode of infrared rays, IC52 is the special-purpose integrated package of infrared rays, its peripheral cell R52, R53, C52, C53, C54, C56 and L are for guaranteeing the integrated circuit operate as normal, the infrared rays of the CF of receiving infrared-ray remote control transmitter 101 emissions is provided with exactly, and it is inoperative to the infrared rays of other frequencies, make the infra-red remote control transmitter 101 of safety cabinet and infrared remote control receiver 103 be the special use of single product by regulating W31, after infrared rays diode D51 receives the next infrared rays of infra-red remote control transmitter 101 emissions, just the electric current that produces a CF is added in infrared rays special IC IC52 input, IC52 just exports a negative pulse electric current and is added on the timing circuit by current-limiting resistance R54, timing circuit is actual to be a monostable circuit, by IC 53, R56, C57 forms timer, time is by R56, C57 and deciding, this circuit is set about 7 minutes, and (owner opens cabinet to sign indicating number and gets and close the Over-The-Counter door time behind the thing and rotate footstalk 5 after surpassing 7 minutes, by just do not have faint electric shock sensation at the finger on the feel contact 7) after the negative pulse electric current is added in timer, positive voltage of output output, by the R57 current limliting, be added on the NPN triode BG41 base stage, the BG41 conducting makes and refers to that sense produces circuit 102 work, when putting in place, just do not export timer time positive voltage, and NPN triode BG41 ends, refer to that sense produces circuit and do not work, R51, R55, C51, C55 is a power filter, and purpose is to make the circuit steady operation.

(2) warning system circuit

Warning circuit by in the cabinet to infra-red remote control transmitter 104(Figure 16 of alarm) and cabinet report to the police outward carry out partly 105(Figure 17) form, infra-red remote control transmitter 104 to alarm is installed in the cabinet, infrared emission tube D61 installs on the cabinet entodorsum, and aim at the infrared rays launch hole and outside cabinet, launch infrared signal, this circuit is by IC64, R61, W61, R62, the no steady oscillator that C61 forms, make the infrared emission tube D61 infrared rays of the modulated mistake of emission continuously, when sign indicating number is not put in place, pull the normally closed K61(microswitch 35 of main handle 6 contact pins, 34 shake-up so that improve antijamming capability (as natural light or other light source)) disconnect, the infra-red remote control transmitter 104 of alarm be can not get power supply and do not work, report to the police to carry out partly and 105 just work.The infrared rays reception triode J that carries out in the part 105 that reports to the police is installed on the building plane, report to the police and carry out the installation of central strange land, (nowadays the residential district of exploitation all or has been equipped with security personnel mechanism on duty in flakes, the warning of family expenses safety cabinet is carried out central authorities and can be installed in this mechanism) infrared rays receives triode J receives continuously in the cabinet that the infra-red remote control transmitter 104 to alarm spreads out of from safety cabinet backboard aperture signal, its operating principle is with infrared remote control receiver 103, make output produce an electronegative potential, by the R75 current limliting, BG71 amplifies negative voltage of output, thereby NPN triode BG72 is ended, the warning oscillating circuit is not worked, R77 is the BG71 emitter resistance, R76 is a NPN triode BG72 base stage current-limiting resistance, alarm is the secondary oscillator, by IC87 and peripheral cell R85, R86, W82, C83 produces an audio oscillation, its frequency of oscillation is determined by peripheral cell, the Control of Voltage that sent here by R84, IC86 is the low-frequency oscillator of 1-2 cycle per minute, frequency is by peripheral cell R81, R82, W81, the C81 decision, when main handle 6 maloperations to the K61(microswitch 35 in the infra-red remote control transmitter 104 of alarm) disconnect, the infrared signal of sending out from safety cabinet backboard aperture interrupts, infrared rays receives three plate pipe J and does not receive infrared signal, report to the police carrying out partly 105 just works according to above-mentioned principle, the square wave that frequency of output output is 1-2 week during work produces a sawtooth waveforms by integrating circuit, modulation next stage oscillator, thereby the voltage that output class is changed voice and transferred like alarm, by R87 current limliting BG82 power amplification, loudspeaker output sound equipment, red light emitting diodes is simultaneously glittering, and C84 is a filter capacitor.K71 is a test switch, so that whether the part of alarm verification execution at any time 105 is in normal condition, in sum warning function maloperation arranged, move, isolation, shielding, short circuit, breaking alarming put means of destruction because safety cabinet is close to the building plane to good use with the space limit restriction robber of minimum.

The utility model is changed the security door that also can become important place slightly, machinery partly can intactly be indiscriminately imitated, owing to be to transplant on the building, the arrangement of warning system should be done some locational adjustment, a comparatively firm protective cover at first should be arranged, all structures of door inboard are contained wherein, in infra-red remote control transmitter 104 mounting cups to alarm, the signal launch hole is arranged on the protective cover side of trolley side, and infrared rays reception triode J is installed in corresponding with it doorframe shelter, and other are not all changed.

The utility model compared with prior art has following several respects characteristics:

1, traditional insurance cabinet sign indicating number action is avoided most surreptitiously looked, although some symbolistic " public coded safe cases " have appearred in applicating modern times technology, but fundamentally solve the deadly defect of surreptitiously looking is not avoided in sign indicating number action most, current electronic lock is widely used, its kind is also more and more, but the electronic lock that can be applied to safety cabinet does not all possess the function that unlocking action is open and don't divulge a secret, even use the most high-new computer technology, this deadly defect is still wherein dying.The patent No. be CN86100207A's " being used in two new equipments on ' miser ' board safety cabinet ", this invention has an automatically rebounding open wicket of energy, the main handle, combination disk, the lock that are exposed on the gate is fully hidden, but if whole actions of opening the cabinet door are stolen looking, and obtaining key or duplicate, wicket and gate all will be opened smoothly.Thereby the utlity model has the safety factor that the function of looking on has improved safety cabinet is not widely avoided in sign indicating number action.2, based on the safety cabinet of frame for movement its to sign indicating number action just can't not carry out by light source, it is of the present utility model that not only simple but also special conception has realized need not also carrying out sign indicating number by any light source to the sign indicating number graticule, get thing and provide convenience for opening cabinet when the special circumstances, for some cabinet master desire row disguise provides possibility to sign indicating number (the code matching part part that will expose during to sign indicating number is used flexible material: cloth cover or rubber cap etc. are covered latent).3, owing to the interlocking effect between traditional insurance cabinet fork, clamp, connecting rod, dead bolt etc. and the main handle is the interlock of dead property, therefore to sign indicating number when not in place if meet the external damage maloperation, certainly will will damage inner body (to the said outside destroy of standing of present safety cabinet, all with the disguise protection of the soundness of its cabinet and exterior part) lock installed on its cabinet door mostly is common drawer lock and pin tumbler lock, because the restriction key of structure can't arbitrarily rotate on lock; The screw key by force if dead bolt puts in place again, key certainly will will fracture, because code matching part part of the present utility model, driving part and snap close have partly all adopted active linkage structure, therefore outside all rotation parts can both under any circumstance be done 360 ° of rotations arbitrarily, and not damaging inner body, burglar's destructive maloperation that a cornered beast will do something desperate or row are stolen all a bit any parts without detriment to inside of the vindictive maloperation that do not become like this; 4, the safety cabinet based on frame for movement can be by rocking the special sound equipment that main handle obtains the feel of combination disk gap position or distinguishes the combination disk indentation, there with stethoscope, the master craftsman of safety cabinet repairing trades also can open the safety cabinet of having forgotten password for this reason, the burglar is as having grasped this gate technique, and the password of safety cabinet has also just existed in name only.The utility model is located on the sleeve of pitching in 20 30 and bearing 57 owing to each is suspended from each code-disc respectively to front and back code-disc 11,12, does not produce friction with axle 26.Active force during with 11,12 actions of code-disc before and after 21 pairs of the dial with the force rate relation (the former is less than the latter) of the holding capacity of dial 21 active linkages in case when realizing jacking block 32 compressing front and back code-discs 11,12 or falling into tooth paddy on its edge, 26 idle running of turning cylinder 26 front and back code-discs 11,12 unmoving axles, therefore the desire row is visited the feel that sign indicating number then can't obtain each front and back code-disc 11,12 gap position, since before and after each on code-disc 11,12 all addition anti-eavesdrop simulation line 55, audiometry also be futile effort.5, be close to the cabinet door with its alarming horn of popular safety cabinet of alarm at present, the row's of being drilled with sound hole, the burglar thinks alarming horn by row's sound hole desire and causes mute ery easy, alarming horn is installed at the bottom of the cabinet of inconvenience destruction, the burglar is if but provide convenience for its spy sign indicating number on the contrary with isolated alert its faint lingering sound of sound of sound insulation materials.Robber to the different alarm shrewdness of existing high-level slightly its function of safety cabinet can take various means to make it artificially out of control: the surveillance zone when infra-red alarm can use special tool(s) to make the action of each position of human body and hand between isolated light source and the infrared receiver; Anti-human body invasion formula offender can pretend self again, the special induction of human body is hedged off from the outer world, the alarm that configuring technical is high-precision, it costs an arm and a leg, approaching have even the cost that want over insurance cabinet itself that has disposes this class alarm and will dwindle the scope of application widely.Warning system of the present utility model adopts the electronic technology that has been widely used to form warning device, its technical matters does not all have difficulty, it is cheap, all part materials are existing market and easily purchase part, yet there is no because of cheap function is also low, still have maloperation, move, isolation, shielding, short circuit, multinomial warning function such as open circuit, because safety cabinet is close to the building plane, put means of destruction to good use with the space limit restriction robber of minimum.

Fig. 1-12 can be used as structure and the assembling drawing of the utility model embodiment, Figure 13-17 can be used as the electronic circuit schematic diagram of embodiment code checking sensing circuit and warning system circuit, required zero, parts, and quantity can be referring to subordinate list, when the utility model was implemented, the technical essential prompting was as follows:

1, produce the center to center distance that the short and small safety cabinet of volume can dwindle lower shaft 26, the preceding code-disc 11 on the last axle 26 can stagger with preceding code-disc 11 front and back on the lower shaft 26, and back code-disc 12 by that analogy.As long as upward the front or rear code-disc 11,12 on the axle 26 does not touch the overlapping arrangement of dial 21 permissions on the lower shaft 26.

2, being fixed on door-plate 2 part inboard and that expose latch board 28 has: front contact seat 15, code-disc location fork 20, microswitch 35, big track base 37, these parts all should the side's of having window on the relevant position of latch board 28, as square window 47, is obstructed in order to avoid latch board 28 moves.

3, the big safety cabinet of tooth on the limit, front and back code-disc 11,12 outer is with 2 moulds, and the mini fuse cabinet is appropriate with 1 mould.

4, because dial 21 has adopted active interlock, code-disc 11,12 o'clock before and after clasp 48 fastens is if rotate footstalk 5, and axle 26 i.e. idle running, and mandatory external force is basic to be passed less than snap close partly, and for alleviating the burden of lock core off-centre 51, limit frame 53 can be used lightweight material.

Although 5 limit framves 53 adopt lightweight material, the rotation torsion that lock core 9 was paid when lock core off-centre 51 held up limit frame 53 by lifting backup plate 52 also will be a bit larger tham medium-sized lock, therefore it is special that lock 8, lock core 9 and key should be done amplification synchronously, and the key materials should its twisting resistance intensity of corresponding raising.

6, in order to improve the anti-eavesdrop effect, anti-eavesdrop simulation line 55 uses the materials should be consistent with conductor 54, and length is regardless of unification, but width should unanimity, is embedded into smooth degree and the slit unanimity of also should trying one's best.

7, can be divided into band and report to the police and be not with and report to the police two kinds, not be with on the warning safety cabinet backboard and needn't be drilled with the infrared rays launch hole, and exempt the circuit relevant with warning, other frame for movements are not all changed.
