Description

A kind of photoelectricity key ring control lock

Technical field

The present invention relates to a kind of lock, be specifically related to a kind of photoelectricity key ring control lock.

Background technology

No matter the key lock that generally uses in the market regardless of its shape, is also domestic or the import lock, and its internal construction has all only adopted a kind of lock mode of series, i.e. pellet locking.In order to improve the safety of lock, key is from yi word pattern to cross, again to three somatotypes, get back to again at last yi word pattern, key bit develops into the groove tooth by heel teeth, and computer is made at random, and security performance has obtained larger raising, also there is producer to adopt double-deck heel teeth type key, as the dedicated lock of certain brand security door.The profile of tooth of key becomes increasingly complex, there is no the auxiliary control of modern machinery equipment and computer, only adding simple and mechanical at all can't the manufacturing with the artificial technology has locked, the straggly cooperation with the length of pellet of height that is exactly still in itself tooth on the key forms locking and opens, and the change of matter does not occur locking principle.As the saying goes: the high chi evil spirit in road is high one zhang, this simple, single pellet locking principle, no matter you the matching relationship of key and pellet make have how complicated, robber for the structural principle that is very familiar to lock, all hand to the expense of arresting not much strength just can open by a lock, namely the said gentleman of lock of people does not lock the person of low position.

Scrutinize current commercially available various key locks, all have following general character:

1, key lock needs to go to unblank with key, so the arrangement of pellet all with center radiation layout towards periphery, always can touch pellet by special instrument from keyhole;

2, pellet is all to be subjected to spring force to make it to converge to the center;

3, it is all neat on round with Radius by the height of on the key heel teeth or groove tooth hypomere pellet top that will be different in size straggly unblanking, and conveys by interior outer lock core relative rotary motion the front end steel disc that internal cylinder is connected and goes tapered end is pushed aside.

4, pellet is all with copper or copper alloy made, is subjected to the impact of lock core diameter's size, and pellet thickness diameter is generally all below 3 millimeters, and after anodontia speciality steel disc inserts lock core, powerful rotation can be opened lock equally.

These common features, for robber's technology unlocking provides possible condition, as long as and possessed can technology unlocking ambient conditions, difficult and just to be not difficult be only technical problem.Robber's various technology unlocking methods prevailing now, wherein the most typical will counting of proving effective most hit the key method and opened by force method, obviously, it is that the robber has seen the structure weakness that pellet adds spring clearly that the key method is hit in use, using and opening by force method is the weakness that the robber has seen pellet material and thickness clearly, and certain hand of suiting the remedy to the case is to arresting.

Although have now many other locksets, as photoelectric combination lock, photoelectricity magnetic control lock, magnetic key lock, Fingerprint Lock, temmoku lock, two sections lock cores dislocation cylinder locks etc., these locks one are prices, and 100 yuan at least, many reaches four or five thousand yuan; The 2nd, unblank to bother, always be not suitable with part for old man or pupil, lack the universal effect in popular market; The 3rd, join the key difficulty, bitting is all more difficult again in the situation that mother key is arranged in other words, and not doing a good job, just must change lock core causes waste.

Having does not have a kind of locking means to can do with the various method for unlocking that present robber uses, does not the unlocking difficulty that develops skill in other words even stay the condition of technology unlocking great-leap-forward? I think to have fully.That is exactly, adopt the variable locking principle and method is gone multiple locking and be a lock that the key once-through operation just can easily be opened, a lock is opened because clever robber also can not be at one time again, same narrow and small working range and space are gone to crack simultaneously several locking means.In addition, a lock can obtain customer's approval, also must consider following factor:

1, except primary safety, that is exactly the convenience that uses, although require concerning the robber lock more difficult open better, concerning owner, when unblanking method must be simple, consuming time must be short, unblank in other words easier, Vietnamese side is just just better; Next is popularity, namely uses scope and adaptation population's problem, and the scope of installing and using must be wide, and wants to adapt to even blind person's use of old man, pupil; The key of lock can not can not too littlely will be easy to carry too greatly best in addition;

2, the shape size, manufacturing cost of lock are wanted suitably, can not be higher than current commercially available similar lock, and install, change and will facilitate as far as possible better.

Summary of the invention

For the deficiency that present various key locks exist, the invention provides a kind of photoelectricity key ring control lock, can solve these not enough problems, make the robber also at one's wit's end within long period at least.And in various aspects such as the shape size of locking, manufacturing cost, eases of use, substantially the same with present commercially available lock.

The present invention realizes by such technical scheme:

A kind of photoelectricity key ring control lock, this lock comprises master lock body and lock core and three parts of liaison circuit; The master lock body comprises that doorframe tapered end hole (1), master lock head (2), tapered end are controlled steel disc (3), electromagnetism lockhole (4), control steel disc moving tooth (5), electromagnet (6), Electromagnetic lock (7), gathering pallet (8), fixedly steel disc (26) reaches (27); Lock core partly comprises internal cylinder front end plectrum (9), internal cylinder (10), lock core cover (11), power switch contact (12), power switch bridge reed (13), LED lamp (14,15), light-sensitive element (16,17), key (18) and the shank of the key (19); Liaison circuit comprises low-voltage dc power supply (20), electromagnetic lock circuit (21) and LED circuit for lamp (22).

the operating principle of this lock is: key inserts 30 ° of internal cylinder rotations, begin to open internal cylinder front end battery main switch: contact (12) coordinates with bridge reed (13), circuit (21) and (22) closure, LED lamp (14, 15) light luminous, light passes lock core cover one end, internal cylinder one end, key, the internal cylinder other end, the light hole that runs through on the lock core cover other end, illuminate light-sensitive element (16, 17), the resistance rapid drawdown, the electromagnetic lock circuit turn-on, Electromagnetic lock (7) is attracted to break away from electromagnetism lockhole (4) by electromagnet (6), key (18) is rotated further, internal cylinder front end plectrum (9) coordinates with gathering pallet (8), continuing to stir tapered end control steel disc (3) moves right, make master lock head (2) withdraw from doorframe tapered end hole (1) and open door lock.

before key inserts the internal cylinder rotation, although Electromagnetic lock (7) has also inserted tapered end and has controlled in electromagnetism lockhole (4) on steel disc (3), but because electromagnetism lockhole (4) is the trough type hole, Electromagnetic lock can not affect moving right of steel disc, so key is as long as just coordinate with pellet and can rotate, after 30 ° of key turns, Electromagnetic lock makes Electromagnetic lock arrive the left extremity of long slot bore on steel disc with the relative motion of control steel disc, but just the bridge reed of key front end has been connected the LED circuit for lamp at this moment, simultaneously also closed electromagnetic lock circuit, the LED lamp is lighted, if lock core sleeve, internal cylinder, the words that light path on the key three connects, light-sensitive element is subjected to resistance rapid drawdown after illumination, the electromagnetic circuit conducting, the electromagnetic lock tapered end is picked up breaks away from electromagnetism lockhole (4), therefore key is rotated further, controlling steel disc (3) is continued to move right, Electromagnetic lock (7) just slides on the control steel disc, key forwards 40 ° of left and right to, bridge reed (13) breaks away from power contact head (12), power circuit has just interrupted, key rotates second again, during the 3rd circle, can repeat the process of above-mentioned closed circuit, during the firm closure of electromagnetic circuit (21), circuit might not conducting, although LED circuit for lamp (21) closure, lamp (14, 15) all can light luminous, if but light hole on the key be not just and the light hole that puts of lock core over against, have at least a light path to be blocked, not illumination of light-sensitive element, make electromagnetic circuit (21) though but not conducting of closure, Electromagnetic lock (7) will pin all the time controls steel disc (3), the control steel disc is locked key to be made it and can not be rotated further, the door lock so do not open, key has pinned light path and causes electromagnetic lock to pin key in other words, namely pinned the master lock head, light hole on internal cylinder is made into long trough and suitably enlarges, before not being rotated certain angle because of internal cylinder, the light hole that lock core puts is being blocked by the entity part on internal cylinder light hole side, if someone wants to remove to explore or measure by the light hole of internal cylinder the accurate location that lock core puts light hole, the structure of internal cylinder light hole has just determined that he is at all out of the question.Simply an electromagnetic lock can be only used in the manufacturing of a bit, more senior manufacturing can increase to uses three electromagnetic lock, in general, use two electromagnetic locks also just safely enough, because even the robber uses X-ray to remove to survey the light hole that lock core puts, two light holes can can't be measured definite pitch-row because of image lamination, remove to open door lock thereby can't produce suitable key.If further improve safety, light hole is favoured key stretch into direction 10-20 ° and drill just passablely, but can make like this key configuration become more difficult.The application of light hole and light-sensitive element, it is one of most crucial technology of most critical of the present invention, iff the power switch and the electromagnetic lock that increase the internal cylinder front end, the robber pries open key lock and also just equals to have pried open electromagnetic lock, do not reach the purpose of ring control at all, light hole, light-sensitive element, the triangular cooperation of electromagnetic lock are arranged, could realize key control power supply-＞electric control light-＞key control again light path-＞the photocontrol electromagnetic circuit-＞the electric control electromagnetic lock-＞electromagnetic lock controls key turns, form light, electricity, key loop control and unblank.

Beneficial effect of the present invention is as follows:

1, the present invention has three fairly obvious anti-effects.Electricity, light, magnetic, key loop control, no matter the robber adopts skilled unlocking or destructiveness to unblank, and all can not open easily door lock.If the spaced apart certain distance of the master lock body of electromagnetic lock and key lock is installed, even the robber adopts sledgehammer to pound the door and also cannot open, if adopt Men Tihou of oxycut sawing intercepting to unblank, can not prove effective in a step, because two electromagnetic locks can be arranged on respectively two diverse locations up and down of door.

2, the present invention under the prerequisite that guarantees high security, uses simple, applied widely.For the lock owner, two apertures that have been only many on the key.Key size, method for unlocking, the speed of unblanking, installation environment are followed with front door lock without any difference.The present invention not only can be used on security door, and being used in and not installing coded lock on safety cabinet additional is also to reach level of security fully.

3, locking of the present invention is made simply, and cost is lower.The key of the key lock that uses in the present invention, just get final product with traditional heel teeth shape key, need not complicated computer and control random printing grooved key, certainly also do not repel grooved key and the cross star key of computerized print, key has become simple, and corresponding pellet has also just reduced, it is also just easy to make, cost has also just reduced, and the LED lamp of increase, light-sensitive element, electromagnetic lock cost will not be higher than the value that reduces, but security performance does not reduce and is greatly improved on the contrary.

4, lock of the present invention has mother key bitting is very simple again, bitting is extremely difficult again without mother key, two light holes between lock core cover, internal cylinder, key three a little dislocation all can obstruct the light and pass, as long as light-sensitive element have one not the working electromagnet lock always have one to be firmly to pin the master lock head.

5, the Kai Heguan of this photoelectricity key ring control lock electricity consumption auxiliary lock, the safety that has greatly improved lock, but very energy-conservation, because there is no the holding state of lock, just in several seconds when unblanking, circuit just can be switched on.

The anti-crafty effect of this lock is embodied in:

1, no matter robber's operation technique is unblanked or brute force is unblanked, rotate separately the internal cylinder door lock of certainly not opening, because after internal cylinder rotates 30 °, Electromagnetic lock will stop the master lock head to control steel disc to continue to retreat.

Even 2, the robber adopts special instrument can pry open key lock, but because the light hole on internal cylinder is a bar shaped long slot bore, can't measure or determine how to get out the light hole coupling that aperture comes just and lock core puts of two suitable distance on picklock, allow simultaneously smooth and easy passing through of two-beam line, thereby stoped the robber to continue to open electromagnetic lock, also just guaranteed the safety of master lock.

Even 3 robbers use destructiveness to unblank, if the light-sensitive element of will jumping over connects the electric wire at its two ends, connect circuit by electromagnetic lock work, this is very difficult; And do not open electromagnetic lock, any technology unlocking or brute force are unblanked, and are all futile.

4, further, when making lock, electromagnetic lock is separated with key lock master lock body, be arranged on during installation door upper away from two positions, like this, even the robber adopts hammer to pound method or oxycut sawing destructiveness is unblanked, make a mess of a door body and also cannot open door, must find another or two electromagnetic lock installation sites all to remove and just can open the door afterwards, this is not to expend little time and strength just can be unlabored.

The specific embodiment

In order more to be expressly understood purpose of the present invention, technical scheme and beneficial effect, the present invention is described further below in conjunction with accompanying drawing, but protection scope of the present invention is not limited in an embodiment.

The embodiment of a kind of photoelectricity key of the present invention ring control lock is take current commercially available general insurance door lock as the basis, reduce the complexity of key and pellet configuration to reduce production costs, increase photoelectric control equipment to improve its security performance, total result is that security performance obtains larger raising, and cost of production remains unchanged substantially or slightly reduction.Yin Ben lock is the additional invention on existing general insurance door lock basis, therefore following explanation and figure are only described the place that former lock changes, unaltered ancillary service in former lock is not added give unnecessary details.

To shown in Figure 6, a kind of photoelectricity key ring control is locked as Fig. 1, and it comprises master lock body, lock core, three ingredients of liaison circuit; The master lock body is comprised of doorframe tapered end hole (1), master lock head (2), tapered end control steel disc (3), electromagnetism lockhole (4), control steel disc moving tooth (5), electromagnet (6), Electromagnetic lock (7), gathering pallet (8); The lock core part is by internal cylinder front end plectrum (9), internal cylinder (10), lock core cover (11), power switch contact (12), power switch bridge reed (13), LED lamp (14,15), light-sensitive element (16,17), key (18), the shank of the key (19) form; Liaison circuit is comprised of low-voltage dc power supply (20), electromagnetic lock circuit (21), LED circuit for lamp (22).

As shown in Figure 1, when locking the door, master lock head (2) enters in doorframe tapered end hole (1), and the Electromagnetic lock of two electromagnetic locks (7) is in the right-hand member that tapered end is controlled the upper electromagnetic lock hole (4) of steel disc (3); The light hole that lock core puts and the light hole on internal cylinder not point-blank, as shown in Figure 4; The bridge reed of internal cylinder front end does not contact with the power contact head of lock core cover front end, and namely two circuit all do not have closure.After inserting key and rotating 30 °, the bridge reed of internal cylinder front end is with two closings of circuit, why key can rotate 30 °, be not only because key has been opened cylinder lock, also because tapered end controls that steel disc (3) afterbody Electromagnetic lock (7) inserts is the trough type hole, Electromagnetic lock does not also play a role; Key turns is at 30 °--in the time of between 40 °, LED circuit for lamp (22) closure, LED lamp (14,15) luminous, two light holes couplings that if two light holes on the key are lucky and lock core puts, the smooth and easy light hole that passes of light, light-sensitive element (16,17) be subjected to resistance rapid drawdown after illumination, the just real conducting of meeting of electromagnetic lock circuit (21), work of electromagnet, Electromagnetic lock (7) are attracted and withdraw from electromagnetism lockhole (4) and no longer stop tapered end to control steel disc (3) to move right, and key is rotated further until open door lock.In light path, light sends from a side of lock core cover, pass a side of internal cylinder, pass again light hole on the key, pass again internal cylinder opposite side light hole, pass again at last lock core cover opposite side light hole and shine on light-sensitive element, can't detect the definite position that lock core puts light hole before internal cylinder is not rotated in order to make the robber, on internal cylinder, light hole is that the lock core wall between two circular ports is cut out, and is linked to be a trough type hole and slightly enlarges.Described light-sensitive element, watt level according to the use electromagnet, can directly use light resistor, or use triode amplified current, also can use photosensitive switch add relay circuit by work of electromagnet all can, light resistor also can change photodiode into, reduced by light resistance as long as can reach, circuit turn-on is not subjected to the not conducting of illumination circuit just; The light-sensitive element that uses should be selected shorter better of response time.According to the needs of security level, one can use one, two, three electromagnetic lock in master lock, must the mating number and LED lamp, light resistor, light hole of the electromagnetic lock of use; Light hole necessarily from lock core front end increase forwards, backwards, because if the robber will make a kind of picklock and unblank, its tip must be to implement the picking lock part, could hole in the back, to pry open key lock be also useless if do not drill through this picklock of unthreaded hole, also bore upper light hole also not necessarily can be just and the light hole that puts of lock core be complementary.

Described light hole, as shown in Figure 5, it inserts at key and is drilled to when lock core rotates 30 °; At the lock core cover, be two through apertures (24) and (25) on the key, and on internal cylinder, be a bar shaped long slot bore (23), it slightly enlarges than the diameter of aperture (24) and (25), as shown in phantom in Figure 1; Before key inserts internal cylinder and does not rotate, the light hole that lock core puts not with internal cylinder on light hole form light-path, as shown in Figure 4; At the light hole oral area that lock core puts, the aperture is drilled wants large, and this is in order to lay LED lamp and light-sensitive element, as shown in Figure 3.

Described " electromagnetic lock is separated with key lock master lock body, be arranged on during installation door upper away from two positions ", can increase like this safety of lock.After electromagnetic lock separate to be installed, separation be that an electromagnetic lock should corresponding increase reaches fixedly steel disc (26-1), (27-1) with doorframe tapered end hole (1-1), master lock head (2-1) and the tapered end control steel disc (3-1) of electromagnetic lock coupling; What separate is that doorframe tapered end hole (1-2), master lock head (2-2) and the tapered end control steel disc (3-2) that two electromagnetic locks are answered corresponding increase and electromagnetic lock coupling reaches fixedly steel disc (26-2), (27-2), the tapered end that increases is controlled steel disc and is controlled steel disc (3) formation interlock by the tapered end in certain attachment device and master lock body, could realize like this locking and unblank effect; Described attachment device can be that steel disc adds lever, also can add fixed pulley with wire rope and realize.

Described power supply generally uses 6-9 volt dc source.The door lock of not opening when preventing the internal electric source shortcoming should put at lock core and drill two miniature apertures, and the power positive cathode patching jack is installed, and in parallel with power supply, miniature patching jack seals with trade mark under normal circumstances, and connecting external power during shortcoming can open the door; It can not affect the safety of lock, does not remove closed circuit because do not insert key, and external power supply is also useless.

Photoelectricity key ring control lock of the present invention has been realized with one, simple key being controlled complicated multiple locking means, careful user may find two apertures many on the key, inner complicated multiple locking is greatly improved the security performance of lock, has accomplished that really pick-proof, anti-drilling, the anti-destructiveness of unblanking by force even unblank; The user unblanks and key carries with present commercially available phase-locked ratio and has no difference; On making, remove the use that complicated key was made and played the manufacturing process of key coupling and reduced the precious metal material from, luminous and the light-sensitive element that increases is cheap, expensive electromagnetic lock part is also one of one or two yuan, so similar phase-lockedly perhaps slightly reduce than equally matched on the manufacturing cost of whole lock and market is greatly to reduce and security performance fully can be with high-end lock than beautiful compared with high-end lock.photoelectricity key ring control lock of the present invention is take yi word pattern heel teeth type key lock and its operating principle and technical characterictic are described as example with two electromagnetic locks, but in Practical manufacturing, one of concrete use, two or three electromagnetic lock, light hole is perpendicular to key and stretches into the direction certain angle that still tilts and bore, use common yi word pattern key lock, or computer is played the yi word pattern key lock of tooth at random, or the star-like key lock of cross locks to make photoelectricity key ring control lock as the basis, need according to security level required, do again and consider as a whole, therefore this example is only for convenient structure to lock, the explaination of operating principle, protection scope of the present invention is not limited to make photoelectricity key ring control lock with common yi word pattern heel teeth shape key lock within.
