Abstract
The utility model discloses an anti-theft photoelectric cipher lock, relating to the technical field of the grating application and the manufacture of the cipher lock. The utility model is characterized in that the anti-theft photoelectric cipher lock comprises a grating cipher key and a lock head which is composed of a grating cipher recognition circuit and a solenoid switch. The upper side of the key is provided with a grating and a cipher hole, and the recognition circuit comprises an indicating grating, a photoelectric sensor and an alarm circuit. The coded combination of the grating cipher key of the device has great quantity, strong confidentiality and difficult counterfeiting. The grating cipher lock has the advantages of convenient operation, energy-saving performance and electricity-saving performance, and can also be matched and connected conveniently with various external devices.
Description
The present invention is a kind of photoelectricity anti-theft puzzle lock of new generation, relates to grating applied technical field and anti-theft puzzle lock manufacturing technology field.Be applicable to the antitheft parts of locking of need such as residential houses, hotel, automobile, warehouse, bank, office, confidential departments.
Present existing anti-theft puzzle lock product has three kinds: (1) electronic password lock, and adopt electronic switch to encode, be divided into button or touch, there is not key, must specify the special messenger to use, be difficult to realize once give away secrets.When unblanking, the electromagnetic actuation distance is big, and electromagnetic switch is extremely taken.(2) mechanical code lock generally uses on safety cabinet, because the mechanical action of having dialled the number, easily by the broken sign indicating number of robber master-hand.(3) multi-functional Safety lock, tapered end is a billiards lock structure, though grotesque key is arranged, key still easily is forged.
The objective of the invention is to avoid above-mentioned the deficiencies in the prior art and provide a kind of and be difficult to forge, the novel photoelectric anti-theft puzzle lock of power saving.
Purpose of the present invention can reach by following measure: the photoelectricity anti-theft puzzle lock is made of grating cipher key and the tapered end with grating password identification circuit and electromagnetic switch.
Purpose of the present invention can also reach by following measure: grating is arranged on the grating cipher key and encrypt the hole.The grating password identification circuit is made of indication grating sensor and warning circuit.Turning cylinder by the lock of electromagnetic switch control is free to rotate, and its top is saddle, and the iron pin slides in three positions of saddle (a, b, c).
Description of drawings:
Figure one is grating cipher key structure chart of the present invention.
Figure two is fundamental diagram of the present invention.
Figure three is electromagnetic switch structure chart of the present invention.
The present invention is further detailed in conjunction with the accompanying drawings below:
Shown in figure one: the leading portion of grating cipher key 1 is fixed with a grating 2, and has 6 to encrypt hole 3, and aperture and pitch of holes are random value, and the key that is only limited to same lock has interchangeability, has improved security performance.
Shown in figure two: the indication grating 4 in the grating password identification circuit is relative with grating 2 on the key 1 at keyhole, read the encryption hole 3 on the grating cipher key 1 and the optical signal of grating Moire fringe by two pairs of infrared emission one receiving tubes in the photoelectric sensor, the signal of telecommunication behind the photoelectric sensor output Shaping, wherein reading hole signal is as control count pulse 15, moire frange signal of grating offers circuit count device 5 count pulses, send into the digital code identifier 6 that " with door " formed by the digital code that counter 5 produces more than three or three, to correct sign indicating number driver 7 work, make electromagnetic switch 8 actions.To error code, warning circuit 9 work, alarm 10 is reported to the police.
Shown in figure three: electromagnetic switch 8 is positioned at the saddle place on turning cylinder 11 tops, when the driver 7 of password identification circuit is not worked, there is not electric current in the electromagnetic coil 12 in the electromagnetic switch, lock turning cylinder 11 can only make iron pin 13 slide into position c from the position a of saddle, or slide into position a from position c, not adhesive of magnet iron pin 13, tapered end is not opened.When driver 7 work, there is electric current to pass through in the electromagnetism iron ring 12, turning cylinder 11 forwards to when making iron pin 13 be positioned at saddle position b, and the iron pin is promptly by electromagnetic actuation, and tapered end promptly is opened.Because the adhesive of electromagnet distance is very little, so required electric current is very little in the coil.
Compared with the prior art the present invention has following advantage:
1, adopts grating technology, coded lock can carry out the grating cipher coding to the grating pitch of different grating passwords, different grating angles is encoded, diverse location to grating is encoded, encoded in the position of encrypting the hole, hole count and the pore size of encrypting the hole are encoded, so combination pin quantity is big, strong security is difficult to forge.
2, use is easy to operate, opens different locks with different keys, as long as with in the grating password key insertion hole, after the identification of grating password identification circuit, can unblank, and the grating key does not have the mechanical rotation action.
3, can connect various external equipments easily, as camera system, computer system, can write down automatically the unlock staff, shooting etc. in important occasion.Connect wireless launcher, can carry out the supervisory control and the management of grating coded lock within the specific limits.
4, because the adhesive of electromagnetic switch distance is little, electric current required in the coil is very little, energy saving.
