The electronic coded mechanical lock is characterized in that a decoding circuit and an electromagnetic driving circuit are arranged in the lock body; a power supply and a coding circuit are arranged in the key; the power supply and a coding signal are connected with the decoding circuit and the electromagnetic driving circuit in the lock body directly, so as to realize the unlocking function. The electronic coded mechanical lock has the beneficial effects that a mechanical lock key and an electronic coded lock key are integrated as a whole, thereby being safe and theftproof; the lock body is not provided with the power supply, thereby avoiding the disadvantage of an electronic lock that the power supply influences unlocking and the application.

Description

Electronic cipher code mechanical lock

Technical field

The present invention relates to a kind of lock, relate in particular to a kind of electronic cipher code mechanical lock.

Background technology

In the lockset of usefulness, the shortcoming of mechanical lock is to be short of to some extent on the function that avoids theft in the market; Electronic password lock is because power supply is arranged at lock body inside, and such structure has limited its scope of application on the one hand, and power supply exhausts or the external power supply outage in also may occurring locking simultaneously, causes the problem that can't unblank.At above-mentioned shortcoming, we have designed a kind of electronic cipher code mechanical lock, power supply is not established in lock body inside, have only decoding, circuit driven by electromagnetic means, and power supply and coding circuit are installed in key case inside, power supply directly links to each other with decoding, the circuit driven by electromagnetic means of lock body inside by key bit with code signal, thus the function that realization is unblanked.

Summary of the invention

The purpose of this invention is to provide a kind of electronic cipher code mechanical lock, overcome the shortcoming that in a single day power supply exhausts or the external power supply outage can't be unblanked of existing electronic lock.

The objective of the invention is to be achieved through the following technical solutions:

A kind of electronic cipher code mechanical lock comprises lock body, lock core and key, and lock body inside is provided with decoding circuit and circuit driven by electromagnetic means, does not establish power supply; Key inside is provided with power supply and coding circuit, wherein:

Described key comprises key bit and key case, is provided with power supply, coding circuit plate, switch in the key case, and power supply and coding circuit plate are by key bit and lock core line conduction when unblanking;

Lock core is embedded with contact assembly, and is connected with decoding circuit printed line road in the lock body, and power supply when unblanking in the key case and code signal enter circuit in the lock body by after key bit and the connection of lock core contact assembly;

The decoding circuit plate is arranged, electromagnetic actuator device and mechanical lock mechanism in the lock body; Decoding circuit is connected in lock core circuit and the lock body, thereby key is communicated with power supply and coding and decoding signal circuit between lock body when realizing unblanking, and passes through the electromagnetic actuator device release, makes the mechanical lock unlatching.

The beneficial effect of electronic cipher code mechanical lock of the present invention is: mechanical lock key and electronic cipher lock key are united two into one safe antitheft; The lock body non-transformer has been avoided electronic lock because the defective that the power issue influence is unblanked and used.

The specific embodiment

Shown in Fig. 1-2, electronic cipher code mechanical lock of the present invention comprises lock body, lock core and key, and lock body inside is provided with decoding circuit and circuit driven by electromagnetic means; Key inside is provided with power supply and coding circuit, wherein: key comprises key bit 10 and key case 1, be provided with power supply 2, coding circuit plate 3, press button 4 in the key case 1, power supply 2 is connected, and key bit 10 and key case 1 is tightened up by insulation spring assembly 8, key bit 10, contact cover 5 with coding circuit plate 3; Lock core partly comprises lock core cover 9 and mechanical lock 11, lock core cover 9 is embedded with the contact ring assembly 7 that two concentric conduction semicircular ring are formed, two contacts 6 are connected as the ground wire of the decoding circuit plate 21 in ground wire and the lock body 20, overlap 5 by the contact simultaneously and are connected with the ground wire of coding circuit plate 3; Lock body comprises decoding circuit plate 21, and electromagnet 15, locking plate 14, positioning stud 17, spring 16 all are fixed on the planker 19, and dead bolt 13 is fixed on the wall of lock case 1; Three leads of drawing on the decoding circuit plate 21 in three leads of drawing on the lock core 11 and the lock case 1 patch 12 by one three core and are connected, thus the power supply and the code signal circuit communication of realization coding circuit and decoding circuit.

When unblanking, key bit 10 is inserted lockhole to put in place, as shown in Figure 3, the power supply 2 on the coding circuit plate 3, code signal line are connected with the contact ring assembly 7 that lock core overlaps on 9 by spring assembly 8, and power supply and code signal input direct by lead again and on the decoding circuit plate are connected.Press the button switch 4 this moment, send a string coded pulse signal on the coding circuit plate 3 and output to decoding circuit by three leads, after decoding circuit is received a string coded pulse, correct through deciphering, send high level by output, the control circuit driven by electromagnetic means makes electromagnet 15 adhesives, the release of pulling locking plate; If decipher incorrect then output low level, can't release.The operation that shuts and standard machinery lock is just the same, shut put in place after, locking plate 14 is withstood by dead bolt 13, and planker 19 can't be moved, so can not carry out mechanical lock open the door (not needing electrification).
