Description
Technical field
The utility model relates to a kind of safety lockset, specifically a kind of electronic cipher code mechanical lock.
Background technology
Lockset is instrument indispensable in people's daily life, and in order to anti-theft protection personal safety as well as the property safety, various lockset is in succession manufactured, but along with the development of unlocking technique, the defect of many locksets also constantly comes out.The marble mechanical lock be used on all kinds of door can be unblanked with master key, and do not resist and pound, not anti-drilling, is easily destroyed.The one-way cipher lock be arranged on safety cabinet also has with sensation with rule of normally unblanking may by what split.
Chinese patent 93232809.1 disclosed " electronic lock " can be equipped with dissimilar remote-control key, the identity of computer to key holder distinguishes, but this is a kind of design of pure circuit, the operation of its program is vulnerable to interference and unstable, while also there is stranger directly to the danger that its actuator controls.Disclosed " electromechanical lock " its password of Chinese patent 89220486.9 distinguishes that part is similarly pure circuit and completes, and then inserts key and just can unblank, if key loss, then just loses second and to unblank barrier, be easily opened.Therefore how to increase size of key, not losing barrier of unblanking together because of key loss, is the key issue strengthening lockset safety.
Therefore design a kind of electronic cipher code mechanical lock and become very necessary, be conducive to the research and development and the application that promote safety lockset more.
Utility model content
The electronic cipher code mechanical lock that the utility model provides, can carry out adjustment combination according to the inner lock core of different codon pair, thus realizes different codon pair and answer different keys of unblanking, and has stopped the loss caused because of key loss, has further ensured safety.
In order to solve above-mentioned technical problem, the utility model adopts following technical proposals: this device comprises carrier base, outer lock core, outer lock core back-moving spring, handle, handle cylindrical cam, outer lock core cylindrical cam, bearing pin, internal cylinder, bearing pin back-moving spring, leading screw supporting seat, leading screw, slide block, micromachine supporting seat, micromachine and electromagnet, described internal cylinder has transverse groove, its internal slide is provided with plural bearing pin, the width of described internal cylinder equals the length of bearing pin, described internal cylinder has cannelure and bearing pin forms keyhole jointly, described micromachine supporting seat is fixedly installed to one end that bearing pin is slotted, described leading screw supporting seat is fixedly installed to the other end that bearing pin is slotted, the housing of described micromachine is fixedly installed on micromachine supporting seat, its output shaft is fixedly installed to one end of leading screw, the other end of described leading screw rotates and is installed on leading screw supporting seat, described slide block engaged transmission cooperation is installed on leading screw, and form self-locking, the two sides sliding-contact that two side and bearing pin are slotted, described bearing pin, bearing pin back-moving spring, leading screw supporting seat, leading screw, slide block, the quantity of micromachine supporting seat and micromachine is equal, two medial surfaces of described outer lock core and two lateral surfaces of internal cylinder are slidably installed, two medial surfaces of described outer lock core have the cannelure that width equals bearing pin height, wherein the cannelure of side is different in the degree of depth at correspondence each bearing pin place, the cannelure of opposite side is fixed with bearing pin back-moving spring at each bearing pin place of correspondence, and the free end of described bearing pin back-moving spring contacts with an end face of bearing pin, described outer lock core back-moving spring is arranged between outer lock core and internal cylinder, and wherein the internal end surface of one end and outer lock core is fixed, and the upper surface of the other end and internal cylinder is fixed, described electromagnet is fixedly installed in the side of cannelure in internal cylinder, and its iron core is arranged in the hole that outer lock core and internal cylinder are opened, described carrier base is fixedly installed in internal cylinder, described outer lock core cylindrical cam is fixedly installed on the upper surface of outer lock core, described handle cylindrical cam rotates and is installed on carrier base, and engage with outer lock core cylindrical cam, described handle is fixedly installed to the upper end of handle cylindrical cam.
Wherein, preferred version is as follows:
Six bearing pins are slidably fitted with in the transverse groove of described internal cylinder.
Described micromachine selects stepper motor.
The corresponding password of each bearing pin in this device, correspondence first password of foremost, above second corresponding second password, the like, the password figure that the diverse location of slide block is corresponding different.When needs are unblanked, first input password, whether controller detects password correct, if code error, electromagnet no power, outer lock core and internal cylinder are fixed together by its iron core, because handle cylindrical cam engages with outer lock core cylindrical cam, therefore handle can not be rotated, and lock can not be opened, when password is correct, micromachine energising on the bearing pin that every codon pair is answered is rotated, the position corresponding to password figure is arrived by leading screw band movable slider, after all micromachines have rotated, the internal construction of this lock completes adjustment, namely the position of each bearing pin top shoe there occurs variation, after inserting key from keyhole, key is applied on slide block and bearing pin is moved, if the key inserted is correct, then bearing pin just shifts out outer lock core, be moved into inside internal cylinder, electromagnet is energized, its iron core is made to shrink back internal cylinder, now swing handle just can drive unlocking mechanism to realize unblanking, if the key inserted is incorrect, width due to internal cylinder equals the length of bearing pin, if the displacement that key ejects bearing pin is less than normal, then bearing pin can still in the cannelure of the original side of outer lock core, if the displacement that key ejects bearing pin is bigger than normal, then bearing pin can extend in the cannelure of outer lock core opposite side, therefore outer lock core can not be pressed, because handle cylindrical cam engages with outer lock core cylindrical cam, therefore handle can not be rotated, and lock can not be opened.
Employing the beneficial effects of the utility model are, adjustment combination can be carried out according to the inner lock core of different codon pair, thus realize different codon pair should different key of unblanking, namely must change the key of specifying after changing password just can unblank simultaneously, the cannelure of outer lock core side is different in the degree of depth at correspondence each bearing pin place, displacement when namely unblanking needed for bearing pin is also different, therefore is difficult to complete by other means unblank, and further ensures safety.There is good application value.
