Description

Electronic password lock control device cipher input

The utility model relates to a kind ofly locks employed device at electronic cipher, a kind of electronic password lock control device cipher input of more specifically saying so.

In the prior art, electronic password lock adopts modes such as keying, touch-control or remote control to input password to controller more, and with the unlatching of control lock, its shortcoming is: the one, and from the external encode input, cause password to give away secrets easily; The 2nd, need memory cipher when unblanking, bring the memory burden to the user easily, in case blackout just can not be opened coded lock; The 3rd, this mode of unblanking does not meet people's the daily custom of unblanking, and is difficult for being accepted by the user; The 4th, when this coded lock and mechanical control lock are used, can not realize the once unlatching of two locks, the input password is opened coded lock earlier, and then opens mechanical control lock with key, makes the opening process trouble complicated.

The purpose of this utility model be to overcome the shortcoming of above-mentioned prior art and provide a kind of be difficult for making password give away secrets, do not need user's memory cipher, can be with key operated and when being used, can realize the electronic password lock control device cipher input once opened with mechanical control lock.

For finishing above-mentioned purpose, technical solution provided by the utility model is: a kind of electronic password lock control device cipher input, its special character is, it comprises tapered end 1 and tape code key 6, and described tapered end 1 is provided with a keyhole, on the tapered end 1 of a sidewall of this keyhole one group of contact 2 is set, each contact 2 links to each other with a lead 5, a memory 7 is set in the described tape code key 6, one group of contact 9 is set on the sidewall, the output input of this contact and described memory 7 is joined.

In the tapered end 1 in the above-mentioned technical solution lock core 10 can be set, described keyhole is arranged on this lock core 10, one group of spring 11 and pellet shot from a slingshot 12 is housed, the then corresponding key bit 14 that is provided with on the described tape code key 6 in lock core 10 and the tapered end 1.When electronic password lock and mechanical control lock are used,, can realize whole unlatchings of electronic password lock and mechanical control lock like this, make things convenient for the user by once inserting key 6.

One group of contact 2 in the above-mentioned technical solution can be the one group of bump contact that directly is fixed on the tapered end 1, also can be one group of conduction ball that is arranged in the tapered end 1, under each conduction ball a spring 3 is set, and each spring 3 links to each other with a lead 5.But later a kind of structure is better, easy to use, conduction property reliable and application life is longer.

Memory 7 in the above-mentioned technical solution can be random access memory ram, programmable storage PROM, erasable memory EROM, electricity erasable memorizer EEPROM, programmable logic array PLA, programmable logic controller PLC etc.

Memory 7 in the above-mentioned technical solution can be arranged in the key 6 by a circuit board 8, and its output input is then joined by circuit board 8 and described one group of contact 9.

The accompanying drawing drawing is described as follows:

Fig. 1 is the structural representation of tapered end 1 in first preferred embodiment of utility model;

Fig. 2 is the structural representation of tape code key 6 in this first preferred embodiment;

Fig. 3 is the structural representation of tapered end 1 in second preferred embodiment of the utility model;

Fig. 4 is the structural representation of tape code key 6 in this second preferred embodiment;

Fig. 5 is the structural representation of circuit board 8 in this second preferred embodiment.

Referring to Fig. 1, Fig. 2, this cipher input comprises tapered end 1 and tape code key 6, described tapered end 1 is provided with keyhole, on the tapered end 1 of a sidewall of keyhole, be provided with one group of contact 2, this group of contact is made of the one group of conduction ball that is loaded in the tapered end 1, a compression spring 3 is set under each conduction ball, the tail end of spring 3 links to each other with lead 5, for avoiding conducting electricity mutual conduction between ball and the spring 3, at each conduction ball and spring 3 peripheries an insulation sleeve 4 can be set, be provided with a memory 7 in the described tape code key 6, this memory is installed on the circuit board 8, the sidewall of described tape code key 6 is provided with one group of contact 9, mutually insulated between this contact 9, and join by the circuit board 8 and the output input of memory 7.

During use the password input of lead 5 with electronic password lock control device joined, in the keyhole that then tape code key 6 is inserted on the tapered end 1 during unlatching, be arranged on one group of contact 9 on the tape code key 6 and be arranged between one group of contact 2 on the tapered end 1 and interconnect, the password that is stored in the memory 7 then is input in the electronics cipher code lock controller by circuit board 8, two groups of contacts 2 and 6, spring 3 and leads 5, then can open coded lock by the control of controller.

Referring to Fig. 3, Fig. 4, Fig. 5, this cipher input comprises tapered end 1 and tape code key 6, a lock core 10 is installed in the described tapered end 1, lock core 10 is provided with keyhole, in lock core 10 and the tapered end 1 one group of spring 11 and pellet shot from a slingshot 12 are housed, on the tapered end of lockhole one side, then be provided with one group of contact 2, this group contact is made of the one group of conduction ball that is loaded in the tapered end 1, a compression spring 3 is set under each conduction ball, the tail end of spring 3 links to each other with lead 5, for avoiding conducting electricity mutual conduction between ball and the spring 3, so will conduct electricity ball and spring 3 is arranged in the collets 13 that are installed on the tapered end 1, be provided with a memory 7 in the described tape code key 6, this memory is installed on the circuit board 8, and circuit board 8 is embedded in the dorsal part of tape code key 6, and one group of contact 9 is positioned at the back sidewall of tape code key 6 and is set on the circuit board 8, the output input of memory 7 is joined by circuit board 8 and one group of contact 9, is provided with the key bit 14 in order to open mechanical control lock on tape code key 6.Structure, the operating principle of this part are identical on the appropriate section on lock core 10 among this embodiment, spring 11, pellet shot from a slingshot 12 and the tapered end 1 and the structure of key bit 14, operating principle and the existing machinery control lock.

During use the password input of lead 5 with electronic password lock control device joined, the lock body of lock core 10 with mechanical control lock joined, electronic password lock can directly be controlled the unlatching of controlled device, be equivalent to twin-lock this moment, i.e. the separate control of electronic password lock and mechanical control lock is opened, and also can control the unlatching of mechanical control lock, promptly after coded lock is opened, the machinery control lock just can be opened by key, and when coded lock was not opened, then mechanical control lock can not be opened.Electronic password lock and mechanical control lock can adopt various known structures.In the keyhole that then tape code key 6 is inserted on tapered end 1 internal cylinder 10 when needing to open, the password that be stored in the memory 7 this moment then is input in the controller of electronic password lock, coded lock is opened, continued rotation tape code key 6 again, mechanical control lock can be opened by 14 of key bits.
