Description

It is a kind of to prevent U-shape lock from being cut and being pounded protective device that is de- and being opened by skill

Technical field

The technical field that this patent is related to is the technical field of safety protection of U-shape lock tool.Specifically, it is related to one kind For preventing U-shape lock from being cut by hydraulic shear and pounding protective device that is de- and illegally being opened by skilled unlocking method by violence.

Background technique

U-shape lock is a kind of very widely used anti-theft product, but does not have to the Method and kit for that key can be opened Very much, generally there are skilled unlocking and destructive unlocking.It is all to implement the purpose of theft property to reach illegal unlock, this In be primarily referred to as the electric vehicle and motorcycle of bicycle, two-wheeled or three-wheel, also have and many be used to lock glass door.

Problems and disadvantages and its reason existing for U-shape lock, and the problem of while solving these problems once encounters:

Since the technology and methods for opening U-shape lock various in modern society are spread wide, the unlocking tool sold on network Be it is increasing, the stolen case of bicycle, two-wheeled or three-wheeled electric vehicle and motorcycle also emerges one after another, therefore urgent need The security protection performance of U-shape lock is improved, to prevent from reducing stolen caused loss in other words.

However, so far, the structure of U-shape lock has but been doomed the obvious always view for being exposed to people of lockhole of U-shape lock Among open country, this is equal to tell illegal unlock person's target place；Again since locking bar is relatively carefully easily cut；And locking bar and lock tongue Connecting portion also easily pounded by violence it is de-, so U-shape lock is easy to illegally be opened, it is also difficult to prevent destructive and technical Unlatching means.

So, the length of the anti-illegal opening time of the U-shape lock among this is to measure U-shape lock quality and security protection One important a crucial factor of performance.

Numerous U-shape lock in the market, in face of confirmed thief, two steel wires or several simple tools can be U-shaped these Lock is opened, and the people for understanding machining both knows about, and processing technology is advanced again, can also generate the error of permission, mechanical dynamic cooperation It also to be exactly that the error and conjunction of the machining of these components permission is utilized there are reasonable fit clearance, skilled unlocking person The dynamic fit clearance of reason pushes lock core aside to achieve the purpose that prize.The combination tool that general sled pushes lock aside is a set of, one of title For " hook " or " single hook ", another tool for cooperating hook to use simultaneously is " small pin for the case ", and also both are cooperated work by someone Tool is known as master key.So-called hook in fact, only an elongated flat bar hard steel, tip have different shape convex The gib head risen can be used to put in sled in lockhole and dial (pushing) pellet pearl；And so-called small pin for the case, it is exactly that one or both ends curve Right angle, front end do to can be inserted into lockhole at flat sheet-like and pin lock core, become the strength bar that lock core can be made to generate rotation, this two Kind of tool with the use of the key point for being exactly so-called skilled unlocking.

So, other than continuous improvement lockset quality reaches reinforcement anti-theft performance with construction is improved, it is had or not Does its method reinforce anti-theft performance? can the technical solution for more preferably preventing illegally opening U-shape lock enough be developed?

U-shape lock is illegally opened in order to prevent, and this patent extends thinking, is not limited to U-shape lock itself, and devising can be with The structure member of U-shape lock effectively combines and the protective device of the mating application of energy, prevents U-shape lock by pirate of the open preferably to reach Purpose

Summary of the invention

This patent technical problem to be solved:

Does is 1 how to take precautions against U-shape sword iron to be cut?

2 be how to prevent from not pounded by violence breaking to take off being detached from locking bar by the strike of external force under lock tongue occlusive state Lock body?

Be 3 how precautionary technology method for unlocking opening lock master is unlocked?

Technical solution used by this patent:

In order to solve the problems, such as these three aspects, the design of this programme only changes with what current U-shape lock industry was generallyd use The structure and quality of lock core and lock body into U-shape lock have significant difference to improve the mode of security anti-theft performance, are new sides Formula；This programme had both been built upon on the basis decomposed in detail to the illegal process steps for opening U-shape lock, and was established On the basis of the structure and function to human body and limbs understood in detail.

One, the problem of shearing-proof about the locking bar of U-shape lock?

Cutting the most-often used tool of U-shape sword iron is hydraulic shear, its main feature is that speed is fast, it is also laborsaving, but common liquid Its dynamics of compression shear is limited always, and clip is also to have width to limit, the width and thickness foot for the object cut if necessary Enough coarse, then the locking bar for being not easy to cut off the traditional U-shape lock of that can not either cut off at all is most of all considerably long, but simultaneously It is not coarse, it thus can easily be put into the clip of hydraulic shear and quickly be cut off, this is also due to traditional locking bar and is processed The limitation of technique, coarseer round steel are more difficult to Bending Processing molding, are also just difficult to obtain coarseer locking bar, this Patent does not need then to process coarse locking bar, but has installed two more coarse steel pipes additional respectively on two locking bars and gone bail for Sheath had not only made common hydraulic shear clip be not easy or cannot be put into U-shape sword iron, but also has made steel pipe socket even if locking bar and thereon It can be placed into clip, also since it is desired that powerful strength is cut, such as, it is desirable to cut the steel pipe of three centimeters or diameter above, It is not easily achieved, because first to cut the steel pipe outside locking bar to cut locking bar, in other words can not so being not easy to cut off Is cut off in addition when hydraulic shear is difficult to cut, other manual cutting modes are just unlikely.

So, the disconnected purpose that applicant thinks that the technical program first aspect to be solved prevents locking bar from being cut is aobvious And capable of reaching of being clear to, it is to set up, the solution of this problem is also open-and-shut, and the being readily appreciated that

Two, the problem of beating is pounded about lock body lock tongue and the anti-of locking bar?

On television or in online video, and in real life we sometimes can see, someone on the other hand grab Firmly locking bar, another hand pound lock body with brick or pound the bond sites of locking bar and lock tongue with hammer, can also make some U-shape locks Locking bar and lock tongue be detached from, and some is also easily, that is because of the U-shape lock lockked, the position of locking bar and the position of wheel Be with distance it is relatively fixed, when the direction for pounding the power beaten that lock body is subject to makes with dynamics that locking bar separates with lock tongue enough It waits, they will be detached from, because they are two components；If being allowed to be combined into an entirety, bear to pound the power beaten when Time would not make locking bar respectively also would not by the power at two opposite directions for being allowed to separate, lock body and locking bar with lock body De- separation is pounded, how to accomplish this point?

Present solution provides a kind of thinkings of solution, exactly when lock body and locking bar are locked, this combinative prevention first Device can protect the connecting portion of lock body and locking bar not and will receive directly to pound and beat, and less will receive separates lock body with locking bar Pounding for power is beaten, and is pounded the power beaten and is all accepted always by lock body protective device and finally disperse and be transferred in protective device, can't It directly pounds on locking bar, in this case, only pounds the power beaten by what manpower applied, be that can not pound to beat to separate locking bar with lock body ?

Likewise, applicant thinks this point from the transfer mode of power physically and principle to understand being also very bright True, it is believed that and it is easier the understood

Three, the problem of being opened about precautionary technology unlocking tool and method?

For illegal unlock person, does not have to matched key and want to open U-shape lock, generally require using two kinds of unlocking works Tool, one such " hook " or the tool for making " single hook ", and another tool " small pin for the case " for needing while being used cooperatively, also Need two hands of attacker good and it is skilled be used cooperatively to manipulate both combination tools, could effectively open, and Also need enough activity spaces that hand can be used effectively to manipulate tool, scope of activities as necessary condition, only These correlated conditions are too usually common, can not cause public note that more lacking the analysis and research to these details, In fact, as long as hindering these details in illegal opening process, destroy or limit, make these it is indispensable must Standby condition is destroyed, as long as being allowed to use simultaneously, can achieve the purpose that lockset is protected not opened illegally, that is, logical The function of limiting to the hand of people is crossed using the apparatus structure of certain limitation manpower activity space range to reach anti-technology unlatching Purpose, i.e. patent device only holds a hand and extend into keyhole front end, be when opening the lock with the key it is fairly simple, One hand or two or three finger can be completed, but a hand but can only one of application technology unlocking tool, i.e., only It can be " small pin for the case " or can only be with " hook ", at this moment another hand can not effectively touch the lockhole of lock body outside device, Even if holding another tool, also can not mating reaction, can not thus cooperate with and not only use " small pin for the case " but also used " hook " complete The illegal unlatching of pairs of U-shape lock, prevents technical illegal unlock from completing, with achieve the purpose that this case solve the problems, such as this one.

Above-mentioned basic theories is applied among this case, technical solution is beaten and prevented to construct a kind of shearing-proof and anti-pound Technical unlocking, and simply say with the protective device that the structure member of U type lockset can be combined effectively and exactly U-shaped is locked U-shape sword iron is regarded as three parts (two locking bars are respectively a part, and the U-shaped portion of bottom is divided into third part) respectively, then Protective case is added respectively, and the lock body with lock core is regarded as the 4th part, also adds protective case, the U-shaped of lock body and locking bar Part use two rectangular steel tubes to be protected respectively, and locking bar part be using two round steel pipes carry out guarantor Shield, then the needs in the flank side surface of rectangular steel tube are fixed on for by round steel pipe, at the both ends of round steel pipe Upper screw thread is processed in peripheral surface, and separately with matched short round steel pipe on an internal surface also processing go up screw thread (as Nut), and be put into rectangular steel tube in advance, it screws on round steel pipe after tightening and is just relatively fixed on rectangular steel tube , but that of U-shaped lock locking bar end cannot be fixed, it has to be movable, Cai Nengsuo, fixed just to lock in the dust Not；But after locking, be in contrast it is fixed, open lock and remove the protection rectangular steel tube housing of lock body and lock body Still separated later

Here in terms of the different differences of protective performance, difference is specifically directed to for whether there is or not in the case where the present apparatus again Lock core structure it is detailed analyze, 1) if lock core is linear type, although this fairly simple, do not have substantially now Someone uses this lock core, is easily turned on, after having the present apparatus, to be lengthened very by the length of limited space, small pin for the case It is more, past structure of right angle tyoe be certainly it is not all right, as what pattern be transformed into, not within the scope of this case, here not Inquire into, in this case it is certainly to be it is no, this is one；Second, the present apparatus can divide right-hand man to use when in use, daily life In work, most people is good at the right hand, and a minority often uses left hand, and few groups of people right-hand man can skillfully use, and work as handle The component 12 of the present apparatus is locked at the left side of wheel, is unlocked and is also used left hand, because the finger of our human bodies can only be curved to the centre of the palm Song, will not be curved to the back of the hand, and left hand is to the manipulation of single hook not as good as the right hand that keeps oneself in practice；Moreover aperture and the lockhole of component 15 It is equally big, and is mutually separated with a bit of spacing with lockhole, so after having component 15, using small pin for the case by other lock core When, will not directly not on, its this individual strength can become the thrust poised, and the requirement for the stability of hand can mention It is much higher；

If 2) lock core is crescent, the small pin for the case of straight similar " work " prefix that its small pin for the case is, without limitations In the case where, it is easy to not, it is easy manipulation, after having the limitation of the present apparatus, straight small pin for the case dying, will be changed to assorted certainly Sample, is not inquired into here, how to be manipulated just effectively, is not also inquired into here；

3) use racing lock, with B grade lock, C grades lock etc. lock cores the case where, the requirement of technical unlocking of such lock core itself Be exactly it is relatively high, with the extensive raising of people's awareness of safety, be also just socially gradually unfolded in application aspect, do not having In the case where having the present apparatus, it is not that cannot be opened by skill, only needs long time that could be opened by skill, there is lucky, technology Alright, it is also to have that the short time, which opens, once broadcasting if on TV；But applicant fails to give attention to after having the present apparatus, How could technical unlocking lock core preferable in this way, and under normal conditions, it is general it is destructive open can also consume it is longer Time and efforts, and be not easy to open, if cutting machine, sound is very big, sawed, can not manage it for the moment with saw, Boring lock core is that will not be drilled directly into

That is the device of this programme design can make more preferable, less good, can also increase substantially antitheft Performance

Moreover the lock of the present apparatus, the planform of lock core can far not seen clearly certainly across several steps, reach lock core Front is ready for good tool substantially, and opposite can save some times；

And have the U-shape lock of the present apparatus, it directly will not just see lock core, i.e., be visited using finger, also be visited less than lock core, It can only go to detect with tool, this just needs to expend the time, and the condition for increasing skilled unlocking requires to allow this illegally to anticipate The figure person that hangs back does not say extinction, at least lowers that probability substantially is possible and certain is with current skill For " small pin for the case " of one of art unlocking tool, usually " L " square or " Z " font, length does not exceed 3 generally yet Very little, after having the present apparatus, existing tool is ineffective certainly, but this programme is also inconvenient to predict, is in a word Making to be varied, operation difficulty can also improve a lot, and the people for having that horizontal reaches that horizontality in other words, It is that will not be put to good use easily

Detailed description of the invention:

Since the principle of the present apparatus is very simple, structure is also very simple, so only needing a width general structure schematic diagram (such as Fig. 1) can be illustrated, subsequent drawing be installation step exploded view (as shown in Fig. 2-Fig. 6, in order to more intuitively show, Subsequent material object picture is as aid illustration)

Above-mentioned apparatus mainly includes following 17 components: (due to having no such device before, so component names have to It is named according to component shape or function and effect etc.)

Component 1: " one section of long rectangular steel tube ", feature；

(1), the requirement of length, height and the width: length is slightly more longer than the width that U-shaped is locked, but for locking glass Except the long U-shape lock of door；Width requirement: width is greater than the straight of the big round steel pipe of the component 2 filled on this rectangular steel tube Diameter；Requirement for height: height is slightly above the height of the U-shaped part of the bottom of two locking bars of U-shape lock；

And width and height are significantly greater than the clip of common hydraulic shear；

(2), specific form: on the surface on one of them relatively narrow side of this rectangle steel pipe, with the center on the surface On the basis of line and central point, the circular hole g1 and g2 (as shown in fig. 1) of two diameters slightly larger than component 2 are had, The center spacing in two holes is equal to the spacing at the center of two locking bars, and being equidistant away from central point, and the two holes can It allows a wherein locking bar for U-shape lock to pass through respectively, but the part for connecting the U-shaped bending of bottom of two locking bars cannot be allowed It passes through, but the U-shaped part of locking bar bottom to be allowed to stay in above-mentioned rectangle steel pipe, so that U-shaped part can not also be cut It arrives, then will not more be cut；And the diameter of one of round hole is straight also greater than common Manual hydraulic cutter clip Diameter will also allow component 3 and portion because it will allow component 2 to pass through and component 2 is allowed to screw in the rectangular steel tube of component 1 with component 7 Part 9, which is also screwed in component 1, to be tightened, and it is relatively fixed on；

(3) and above-mentioned two circular hole respectively by rectangular steel tube port direction be respectively provided with again respectively one it is rectangular Shape mouth D1 and D2, the width of rectangle hole are slightly larger than the diameter of locking bar, two sides of the lie farthest away of the two oblong openings Distance should be slightly longer than the length of locking bar, any one in such two locking bars can be from any one hole on component 1 half It is partly pierced by component 1 again across component 1 and from another hole, but the U-shaped part of two locking bar bottoms can be stayed in into portion in assembly In part 1；But because the locking bar of glass door lock is too long, it should not be designed to two rectangular mouths accordingly, and be designed to Two U-shaped mouths are good with a rectangle hole with a U-shaped mouth, because if that is grown still all with rectangle hole Degree is just too long, because the U-shaped lock length of lock glass door is likely to be breached 30 centimeters or so, and component 1 and need not be with so much The of material

Here the side that g1 and D1 have a quarter is perforation, and g2 and D2 are also equally to penetrate through.

Component 2 and 3: " same two sections are slightly shorter than U-shape lock locking bar, and externally threaded round steel pipe is carved at both ends ", Feature:

(1), its diameter outline is less than the circular hole opened on component 1, to facilitate this component to be inserted into the round hole on above-mentioned component 1 It is interior, and the quarter internal thread round steel pipe for the component 7 and 8 being put into component 1 in advance with another segment respectively is threadedly coupled On；

(2), the peripheral surface at this two round steel pipe both ends is carved with one section of external screw thread respectively, can be respectively by component 7,8 Round inner thread steel pipe with 9,10 is put on, and can be tightened, and can be relatively fixed on above-mentioned component 1.

The both ends of component 2 connect component 7,8 respectively as shown in Figure 1:；The both ends of component 3 connect component 9,10.. respectively

Component 4 and 5: " the short round steel pipe that the same internal diameter of two-section is greater than the outer diameter of component 3 ", feature:

It (1), is to cover in the outer surface of component 3, and internal diameter should be greater than the outer diameter of component 9,10, it is bad when not so lock It puts on；

(2) after wherein component 4 covers the round steel pipe of upper-part 3 outside the locking bar that U-shaped is locked, wheel spoke is not being passed through Between gap protheca on, for reinforcing the protection to component 3, component 5 then U-shape sword iron and component 3 pass through wheel spoke it Put on again afterwards, and for reinforcing the protection to component 3, be the anti-main component cut because wheel be it is various, The interval and gap of its support spoke are also to vary, and too small requires component 3 also will corresponding tiny, institute With handle designed here as the such component 4 or 5 of two-section without pass through between wheel spoke.

Component 6: " as the internal-and external diameter of component 4,5, the length of length and component 4,5 adds up almost the same, about phase When pervious one section of round steel pipe is not truncated in component 4,5 " because the locking bar of U-shape lock only need one across wheel spoke , another need not pass through, therefore this root is used to the form for being not necessary to be made into truncation of guard block 2

Component 7,8 and 9,10: " it is four sections same slightly short, inner surface is threaded, size and component 2,3 it is mating, It can be tightened in the round steel pipe at the both ends of component 2,3 respectively, be equal to four nuts ", feature:

(1), the round hole opened on above-mentioned component 1 is had a diameter larger than, it cannot be from the circle on component 1 to limit this component Hole passes through, but can be put into advance among above-mentioned component 1, and is covered on a locking bar of U-shape lock in advance；

(2), it is also carved with screw thread on the inner surface of this round steel pipe, when nut, the screw thread specification and above-mentioned component 2,3 External screw thread it is mating, can be screwed on respectively with the screw thread on component 2,3, and can tighten；

(3), length does not have to too long, can be put into advance in component 1, after screwing on component 2,3, can securely connect and phase To the surface for being fixed on component 1.

Component 11: " one section of rectangle steel pipe ", when being mainly used for anti-pound, undertaking and transfer to external violence are special Point is:

(1), length and width is all larger than lock body；Thickness is about the height that the thickness of component 9 or 10 adds the half of lock body Just

(2), form Design: on two wider sides of this component, on the basis of central point, on wherein surface Corresponding site is respectively provided with one " sleeping 8-shaped " hole A1A2 and B1B2, as shown, be small one and large one two circular holes but It is the part for having the side of a quarter is perforation, the center spacing of two of them aperture is the center spacing of two locking bars, two The center spacing of macropore is also, and big hole should be slightly bigger than the outer diameter of part components 8,10, can pass through for 8,10, but aperture Diameter to be less than component 8,10 accordingly；8,10 cannot be allowed to pass through, but be slightly larger than the diameter of component 2,3 again, allow 2,3 Inside can be passed into；

(3), it is then opened on the surface on another corresponding wide side of this component and is slightly larger than lock there are two partly overlapping The characteristics of rectangle hole c1 of body, the two rectangle holes is that a both ends are long, two hem widths, but middle part is overlapped, as schemed institute Show (this opening is in the bottom of this component), is also provided with one small section of small length for being slightly larger than locking bar diameter in one end of the configured openings Square orifice (with facilitate at the top of the bar of one end locking bar from the place opening A1, B1 of above-mentioned " sleeping 8 words " shape into this component when Wait, will not because of component 11 thickness low LCL and make a locking bar that can not pass through component 11 and be withstood, into passing through in other words Not component 11, the length on top of the aperture position of this notch matched with lock tongue with what is opened on locking bar relative to locking bar Degree is related), it is also separately provided with one section of short oblong openings for being slightly larger than " component 15 " at the middle part for the rectangle hole opened, in this way Lock body can partly enter this through the opening that this is generally rectangular together after covering upper-part 15 and with component 15 In component, and respectively with " sleeping 8-shaped " is also had from the surface of another relative edge tapping when be inserted into and with component 2, two locking bars of the component 8,10 of 3 ends screwed on are locked；(statement may poorly understand herein, please refer to specification Attached drawing 1, as shown, Wo8Zi Xingkou is at the top of this part)

(4) and in the corresponding position at the both ends on the surface on the side at the place for the double slots for being provided with overlapping it respectively opens respectively There are two screw or rivet holes, for connecting with component 12, can also such as use screw and nut within component 12, then twist Silk after upper near the disconnected nut of moat, accordingly even when nut loosening, will not fall, in this way, being torn open using spanner, general feelings It is also to remove again under condition, is commonly called as " stripped thread "

(5) this part is after lock body and locking bar are locked, because lock body is half into this component, by the form of slot The limitation of modeling structure, can not lateral relative movement again, the aperture that also therefore component 8,10 also cannot again to " sleeping 8-shaped " As soon as macropore cut and move laterally, also and then play the role of undertaking and the power beaten is pounded in transfer, because locking bar is packaged completely Come, be fully protected, when making when pounding the power beaten and being applied to above component 11 of lock body and locking bar point, component 8 and 10 Undertaking effect can be played, and is transmitted on component 7,9 again by the steel pipe 2,3 of connection, and be transmitted on component 1, such lock body does not have It is stressed directly, locking bar is not also stressed directly, and is not just separation if removing strike lock body from the inside of component 12 Power, but can be understood as a kind of centripetal power for promoting lock body close to the rush in locking bar direction, so no matter how pounding in this way It beats, lock body will not be made to separate with locking bar, but can move laterally after unlocking, it can be from " sleeping 8 words " shape hole That big hole site is withdrawn

Component 12: " one section of long rectangular steel tube ", feature:

(1), length is more longer than the lock body that U-shaped is locked, and the needs depending on preventing skilled unlocking degree, longer anti-skill is opened Intensity it is better, one of them while surface on be also provided with the face of 11 bottom of component while on the dual stacked opened The corresponding similar opening of the opening of rectangular form, c2 as shown in the figure, and partly passed through for lock body, but because it There is no " sleeping 8 words " shape aperture of the another side above component 11, cannot individually preventing pounding, if pounded without design part 11 The power beaten still can be such that lock body separates with locking bar, but can be used for anti-skill and open, and combine together with above-mentioned parts and be applied in combination Words, can also prevent cutting；If component 11 is placed on inside, what the surface of this component should open is the hole of " sleeping 8-shaped " ?

(2), width and height, that is, this component inner space requirement: hold lock body in a hand and go to cover in U-shaped On locking bar, slightly room for maneuver when locking is advisable with that can accommodate a hand, big to be possible to that two are put in Hand, without this necessity, and a too small hand is opened also and inconvenience and rivet hole there are two respectively opening on the side at both ends respectively, For being riveted over component 13,14.

Component 13: " one piece long of L shape steel plate ", it is characterized in that: the height and the width of this part are slightly less than above-mentioned component 12 Rectangular steel tube corresponding side width and height, effect is one end of the rectangular steel tube of packaged unit 12, and in our department What is be spaced on the surface on the narrow side of part opens there are two rivet hole, for being fixed on one end of component 12

Component 14: and " one block of L shape steel plate ", it is characterized in that: the height of this part is about the half of component 13, for half The other end of the rectangular steel tube of packaged unit 12 can allow palm to protrude into and use key in component 12 there are the conduct of the opening of half The path of unlocking, likewise, also opening on the surface on relatively narrow side, there are two rivet holes, good with screw and nut, but, spiral shell Mother preferably will be close to nut silk moat after tightening is disconnected, and such nut loosening also only understands stripped thread, is generally not likely to be rolled over by spanner Fall, it will not be because being fallen by vibration

Component 15: " one section of rectangle steel pipe ", it is characterized in that:

(1), length and width is all larger than lock body, can cover on lock body, and length is equivalent to the more than half part of lock body, but is shorter than Empty spacing of two locking bars in other words between two lockholes will affect two U-shape sword irons as soon as not so can at least block a lockhole, It does not lock, so should all slightly have distance away from both ends lockhole

(2), as shown in Figure 1: a side of this component surface central point position, it is big to be provided with one and lockhole etc. Circular hole m2, and on the both sides in this hole, also opens that there are two rivet hole H1 and H2 on centerline, and stamps rivet, on lock body After putting on this component, when opening the lock with the key, the aperture that can only first pass through this component could pierce into lock core hole m1 again to be opened Lock, needs the position to this aperture when opening every time in this way, including thering is component 12 to protect this component and lock body jointly it Afterwards, the shape of the lock core in the lockhole on lock body can not with the naked eye observe directly, and stamp riveting loading onto component 16,17 After nail, the lockhole on lockhole and lock body on this component has been separated a bit of spacing, makes small pin for the case when skilled unlocking To still lean against, better other requirement improves very much, the thrust for the arm to poise instead on lock core side, along with lock exists After lock is on tire, the height away from ground, factors, the upper body position of people and the head such as turning angle of hand and arm, eye Height and the factors such as limitation of position want the shape for detecting lock core or further after the reinforcement protection for having this component The structure of speculative arbitration lock core, such as touches lockhole with finger, touch less than, in this way, think direct detection to lockhole and lock core shape If state, condition and requirement can be higher, after lock lock is on wheel, do not exceed the knee of human body highly, i.e., usually will not be high In 50 centimeters from the ground of height, and the sight of human eye will not turn round, be difficult to see squatting down and using light searchlighting and It is technical to open it is clear that also can be longer on the step of finding out lock core form in this way and time, and if it is not known that if lock core form Lock is not just known where to begin, and the owner locked has key, and is the form of known lock and lock core, and unlocking is need not laborious both Between there is significant difference to rivet upper two small L shape iron plate components 16,17 on the rivet hole of this component, further to block From the sight of both ends observation engagement mechanism

Component 16,17: and " two fritter L shape steel plates ", it is characterized in that:

The height of this part is about that the interior height of component 15 subtracts the height of lock body, and width is slightly less than the inner width of component 15, and Be provided with a rivet hole H3 on the narrow side of component 16, be provided with hole H4 on component 17, in order to the rivet hole on component 15 H1, H2 are connected by rivet.

Acting on has two o'clock, and 1) both ends of the rectangular steel tube of packaged unit 15 after being packed into lock body are used for, make the illegal skill person of opening The form and construction of lockhole can not be seen from any end；

2) for strut component 15 it is with holes while with have on lock body lockhole while spacing, for when anti-skill is opened using other The period of the day from 11 p.m. to 1 a.m is bad to be directly born against on lockhole not, can only vacantly be gone to push the difficulty for not improving that hand manipulates tool when skill is opened, be reduced A possibility that being opened by skill

The general description of attached drawing 1 are as follows:

The beneficial effect of this patent is:

With significantly preventing U-shape lock locking bar from being cut, prevent lock tongue and locking bar from being pounded de- and lock core can be prevented by mesh The advantages of preceding technical unlocking tool is illegally opened makes such as to hit a spoon method, various tool and the electric drills of going into operation fastly from key hole drill The illegal opening ways that the rotten lock core etc. that spuds in opens U-shape lock are lack scope for their abilities, reinforce protection U-shape lock tool safety to reach Purpose, and in existing lockset security precautions technology, it seldom occurs through the limit to human body and limb activity range System, be primarily referred to as here by arm to a hand, palm, finger unlocking path and movement on limitation, and then to prevent U-shape lock is only illegally opened, also the therefore research and development to the theoretical knowledge of relevant range and device in kind or the product of application The expansion of directionality has been made, has also had the field that safety guard specifies a new research and development for U-shape lock from now on And range.

The illegal U-shape lock of opening that really at least can greatly extend also has the required time expended in practice, makes non- The time cost of method opens U-shape lock person greatly increases, and also enables the person that opens U-shape lock be found, the risk that is booked is significantly improved, Good deterrent effect is played to preventing trouble before it happens, this selects the protection of product according to actual needs depending on user completely certainly Grade and determine.Also certain basis has been laid to develop not had by the U-shape lock of pirate of the open in the future.

Specifically, illegal opener is to hope at a glance first after U-shape lock has this to reinforce protective device Lockhole, can't see lockhole also can not just prepare corresponding unlocking tool in advance, and have water pipe precaution before keyhole, even if It is also to be difficult to feel the shape of key with singlehanded finger, if going detection with tool, takes some time, as existing Turn on U-shape lock within only several seconds and do not reproduce again then

Illustrate several results for opening U-shape lock mode under patent device protection:

Prevent it is technical open U-shape lock in terms of:

1 master key method, existing tool are not opened, this makes an overstatement absolutely not, because existing tool falls short of, even After improvement extends, only also it is difficult to open with one hand, it is desirable to which effective manipulation unlocking tool opens U-shape lock in a limited space Also by no means easy, even if there is a possibility that very little, nor what everybody can accomplish, it can less accomplish easily, Even if someone tempers for a long time, a bit complicated U-shape lock of unlocking core is also impossible to, such as blade lock, racing lock, and side column lock etc., at least It can reduce and reduce the probability illegally opened；

2, " hitting a spoon method ", it is also not possible to；Because hitting spoon method to be gone to make the tool similar to single hook with the speed being exceedingly fast, adding The U-shaped of the dress present apparatus is locked, and applicant is considered that can not can be opened with spoon method is hit

Moreover it is also impossible for cutting manually.

Moreover if opening by force for " turning round spoon " can be prevented to a certain extent, with blade lock core with idle-run lock pin combination Unquestionable etc. " C " the grade lock core combination in other words of so-called " B grades super " lock core, the anti-performance illegally opened can have aobvious It writes and improves that is not too strong opens not within the scope of this case.

To sum up, this programme has the social effect of highly significant, and taking place frequently for burglar will can be reduced after being widely used There is hundreds of millions of bicycles in situation, conservative estimation, China, there is hundreds of millions of electric vehicles, and there are also hundreds of millions of motors Vehicle, there are also the motor vehicles of hundreds of millions of disc type steering wheels (component 11 to be lengthened to after certain length and can be used to lock direction Disk), play the role of to the social life of people certain positive.

Shortcoming is that, because the device of this programme is all metal steel construction, steel have certain weight, for portable The user of weight sensitive may feel some inconvenience, only more pay attention to bicycle and two-wheeled or three-wheeled electric vehicle and motor The client of the safety of vehicle can gladly select, so also needing that client is allowed to understand correlated performance in popularization and application, also have one Longer time period only applicant believes that, this product be easy to for user receive other than its practicability, it is another It is a the reason is that its material cost is cheap, for the sample manufactured by the applicant, not counting if component 12, with current If present price in the market calculates, the market price of material cost counts component 12 in also less than 15 yuans, with regard to property less than 10 yuan It is acceptable, and sample has worked it out for valence ratio

Specific embodiment:

In order to further illustrate the principle and structure of this patent, carried out now in conjunction with preferred embodiment of the attached drawing to this patent detailed Describe in detail bright, however the embodiment is only to provide explanation to be used with explanation, cannot be for limiting the patent protection model of this patent Enclose

The most preferred embodiment of this patent will now be described；First component 7 and 9 shown in Fig. 1 is put into 1 rectangular steel tube of component It holds, then any one locking bar of U-shape lock is penetrated in component 1 from one of opening on component 1, and is each passed through Component 7 and component 9 (such as Fig. 2), then that root locking bar penetrated is pierced by component 1 from another opening, such locking bar bottom U-shaped part is just left on 1 inside of component；

Component 2 and component 7, component 3 are connected with screw thread in the inside of component 1 with component 9 and tightened again；

And component 8 and the other end of component 2 are connected, then the other end of component 3 and component 10 are connected；

When locking,

1) first component 6 is through on component 2；

2) component 4 is through one section of component 3 above again, here, component 3 is such as both the first layer clothing worn to locking bar Clothes, component 4 is such as both the second layer clothes worn to locking bar, and component 4 is a small half of length for being approximately equivalent to component 3, So also need later component 5 also covered on another section of component 3 side by side with component 4 (but be component 3 pass through vehicle Just put on after between the spoke of wheel), and by the front end of the component 3 with locking bar and component 10 together pass through wheel on spoke it Between gap, in this way, either component 4 or component 5 be without pass through wheel, but the spoke both sides of wheel but have on one side There are component 5 in component 4 and another side, are when passing through spoke because of the component 3 above locking bar and locking bar, due to the outer diameter of component 4 Larger, the gap of wheel spoke is not big enough, can be blocked, and causes component 4 and 5 if it is can not pass through wheel if whole, Two-section is had to be designed as, whether component 4 or 5 is also there is no need to pass through in this way, because the protection of the another half after passing through is It is completed by component 5, but some motorcycles only have three, five spokes, the gap between these spokes is larger, it is also possible to Passing through, that is with regard to more preferable, as soon as directly with whole a thing more saved, but be will not influence and used and prevent cutting performance such as component 6；

3) after being also through component 5 on component 3 side by side with component 4, component 5 and component 10 close to outline between end Micro- there are gaps, and the gap stayed is also slightly larger than the thickness of component 11, because component 10 will also penetrate in component 11, This is also the reason of diameter in the hole A1, B1 is greater than the diameter of component 10；

4) two single u-shaped locking bars of component 8 and component 10 will be cased with respectively again together with component 8 and component 10 respectively from component 11 On the position A1 and B1 of " sleeping 8 words " shape opening opened pierce into the rectangular steel tube of component 11, then move laterally to " sleeping 8 words " The position A2 and B2 of shape opening, since component 11 and 12 is the association connected with rivet or screw, the end meeting of two locking bars There is the case where entering component 12, the length depending on locking bar determines, the long meeting of locking bar enters, and less long will not enter, Bu Guowei It is applicable in and versatility, corresponding site on component 11 and 12 has opened one small rectangular opening all without exception to facilitate long lock Bar penetrates, and will not can enter, cannot be locked on component 11 and 12 because withstanding on；

5) component 15 is put on lock body again, and is put into togerther in component 12 together with component 15, and with elder generation from component 11 The locking bar that other end is put into component 11 is inserted into lock body herein and is combined (on two apertures of H1 and H2 of component 15 in advance It is a bit of at a distance from lock body to allow component 15 to strut to stamp two rivets, makes the key hole and lock body opened on component 15 On lock core hole, stay a little small spacing)；

6) lock body is promoted to the inside of component 12 toward 11 internal direction of component in this way, and lock body is partly through component 11 with 12 binding site, i.e. lock body have half to be inserted into component 11, and another half stays in component 12, and lock in locking bar On, the state of lock body is about half in component 11 at this time, and in component 12, used that hand moves back another half by key Out, it completes, such locking bar is together with component 1-10 all by the shapes and sizes and lock of the oblong openings on component 11 and component 12 Partly penetrate component 11 and the other half state being through on component 12 of body are limited, without returning to from the small end of Wo8Zi Xingkou Big end, after only unlocking, after taking out lock body from locking bar, after lock body no longer limits, the components such as locking bar can just exit unlock, wish Hope auditor be apparent that between structural relation, be due to component 11 morphosis limit each component and locking bar with Lock body can be by such as opposite positioning after locking

As described above, the designed apparatus structure conceived of this programme is simple and practical, principle is also very simple, is suitable for promoting.

Actually this programme can simplify implementation, such as removes anti-pound and beats function, simplifies anti-skill and open function, only retain shearing-proof Function is opened with the anti-skill in part, these can voluntarily be selected to determine by user

Specifically, the function that component 1,4,5,6 can have shearing-proof is used only, such as along with component 12,13,14 is Can have the function of that shearing-proof and anti-skill are opened simultaneously, it is such as complete as only can simply possessed the function that anti-skill is opened with component 11,12 Portion uses, and can possess three functions described in this case.

Above content be combine specific preferred embodiment to made by this patent further description, and it cannot be said that Specific implementation of the patent is only limited to these instructions, for this application person of an ordinary skill in the technical field, Under the premise of not departing from present design design, several deduction or replace can also be made, that is to say, that present patent application is simultaneously It is not only limited to the specific structure of above-described embodiment, the equivalent transformation of other similar structures each falls within the protection of present patent application Range

So far, applicant thinks that the activity space by limiting limbs proposed in present patent application reaches such as this case title Shown in three kinds prevent that the method for illegal this problem of skilled unlocking has practicability, be achievable, and general herein On the basis of thought, sample is manufactured out, large batch of can also produce in the future, meet method invention and product The related specifications of invention have novelty, creativeness and practicability, and are simple to manufacture, low cost, will be answered extensively With being beneficial to society, and application range and group are numerous.

And applicant believes that have many loss bicycle, electric vehicle, the people of motorcycle and trolley know about and have It realizes general civilian the people of the lockset safety of the vehicles expected strongly is for example taken 2,000 yuan and bought After electric vehicle, in an unguarded moment, vehicle, which is outputed, just to disappear in an instant, and is likely to again can not find, then very One may be repurchased again, is then likely to also lose, and this thing is all occurring daily, and the people encountered is at a complete loss as to what to do, and is One social reality problem having no alternative, so three kinds of preventing functions of this case are to adapt to this from this mood of user The social demand of aspect, and cost performance be absolutely it is receptible, some brand locksets on the market, are known as and use at present High-quality steel, special steel material, be known as anti-16 tons of hydraulic shears etc, its price be in comparison it is quite high, it is some Can with good lock core, and in this way, still which anti-hydraulic shear than present design? there is no the several of the present apparatus Prevention intensity just is opened without skill, therefore the present apparatus is also advantageous, the anti-physics for breaking lock tongue and locking bar in this regard The principle of power on applicant believes that your office be also should understand, so, technical products with this programme at least with It is existing using only U-shape lock, in contrast, be on the anti-theft performance of the security protection of the vehicles exist it is apparent Compare sexual clorminance, and existing for a certainty.

If the theoretic definition of activity space imparting one or general to the limitation arm palm finger in this programme If thought, applicant feel be other side in ergonomics application, be the application of inverse ergonomics, human body Engineering science is to extend the function of human body in the environment, and this case is limitation body local function, but is all applicable, and It is beneficial to actual, that can be widely popularized

Applicant thinks: this programme can largely improve the antitheft of the U-shape lock of all existing bilateral open types Performance, and the more preferable that can have made is in terms of the manufacturing cost of the sample in the most a schemes for disregarding component 12,13,14, with mesh Preceding market price meter, material cost are no more than 8 yuan, relatively independent can select；If whole, material cost is no more than 15 yuan, with If its energy band is compared to the degree for the security performance of user improved, comparison sexual clorminance among these is to be enough that user is allowed to select ?

Also, applicant further believes that U-shape lock has been already a kind of product being saturated on the market, even saying is A kind of oversaturated product was not also, then this solution be relative to the raising of a kind of anti-theft performance and perfect, three Anti- performance be it will be apparent that for U-shape lock, be for a user it is useful and harmless, remember the boss of true lattice gold Once said in one grade of program of Shenzhen platform, it is any can the innovation that is promoted of quality to existing product and performance, all There is wide market, be all well worth doing

Which finally, the essentiality content of applicant's illustratively the technical program, that is, can improve beneficial in terms of Performance and social agency:

Essentiality content one only needs component 1,4,5,6 that U-shape sword iron can be protected not cut；

Essentiality content two, in the notch connecting portion on the anti-lock tongue position pounded on lock-off body and locking bar, usually Locking bar is held on the other hand, and the other hand, which pounds lock body and locking bar with hammer, that surface of lock body of contact, will not go to pound lock core hole institute Face because the purpose pounded be separate lock body with locking bar, rather than instead promote lock body at a distance from locking bar, be separation Power, rather than the more similar power of the two is made to be easier to break for not having to the lock tongue that key can be locked, For stretching to be perhaps not too much easy to break by the lock tongue of mechanical action formula for lock tongue, but it is lasting pound, it is also possible that It smashes, even if pounding not bad, the present apparatus on adapted, also without apparent harm, and can only reinforce its anti-theft performance, at most Exactly made anti-to pound performance more preferable；

Essentiality content three, in terms of anti-skilled unlocking, it will be assumed now that have two the same U-shapeds locks, one has This protective device, one does not have, and compares actual effect,

Even in the present apparatus that the only anti-skill for the simplification version that component 11 and 12 and 13,14,15,16,17 is used only is opened In the case of, compared with unprotected once, not the U-shaped lock of the present apparatus it is at least remote every several steps it is seen that lockhole and Lock core, deducibility lock core construction is spring marble lock core or blade lock core etc., can prepare corresponding tool early,

And have the present apparatus, cannot be directly viewed lockhole, also can't see lock core, even connect touch lockhole or lock core come into Row, which is inferred, to be also impossible to, it is necessary to be visited with tool, or first be understood fully that lock core constructs with illumination imaging tool etc., this needs certain Time and tool equipment, that is to say, that the time of consumption can be longer,

Secondly, in the convenience of operation unlocking tool, the not no lock core of the present apparatus, can two hands operate simultaneously,

And have the lock of the present apparatus, there can only be a hand to protrude into component 12 from semiclosed end, and be from the side of component 12 It protrudes into, is exactly backhand with the another right hand then will be opened with left hand if it is what is locked with left hand, because we are usually such as Fruit puts two hands together, it is found that the palm of the hand be it is opposite, right-hand man is anti-, and due to can only be into a hand, that , hand think after entering simultaneously using two kinds of unlocking tools and again in a limited space in, and right-hand man can limited In the case where, can two kinds of tool open lock cores of manipulation effectively and quickly will not be too easy, it is more difficult than the situation of the not present apparatus Degree wants high more, even if someone can accomplish, also never having under too many people at will does several can accomplish, and likewise, its energy The anti-theft performance of the lock made is more preferable, and unique deficiency is exactly the misgivings in some few selections of the meeting to portable weight sensitive, no It crosses for the vehicles of dynamic device, if always worrying the safety of the vehicles when being not desired to go out, is not desired to If just invisible in an instant, the present apparatus is undoubtedly when for the preferred in optional

As for saying, other unlocking modes such as first destroy the present apparatus, that is just not belonging to precautionary technology unlocking Scope has the time for destroying the present apparatus, not as good as directly going to cut locking bar, but in contrast, if with handheld portable Angle grinder (hand sanding turbine) goes to cut, and the thirty or forty second is not arrived in general 15 seconds of the present apparatus, but noise is very big, it is evident that dares bright If doing so mesh gallbladder, is found the probability being booked just and is not little by little, and have one minute of the present apparatus all not necessarily It can cut off, and if cutting one minute, it is sufficient to generate the high temperature that human body not directly contacts, and the noise of longer time Also it is enough to cause neighbouring vigilance

So above-mentioned 3 points be the technical solution for the design essentiality content, mass product this for U-shape lock and Speech, will promote its performance, that is afraid of promotion only a little, and has extensive social benefit, and innovation creates this Just it is not easy, country advocates energetically now, so your office's approval asked.If being given the ratification, applicant to produce daily 100 sets of small-scale production amount, it is expected that 1 year less than 40,000 sets, 10 years less than 400,000 sets, 20 years less than 1,000,000 sets, phase The bicycle hundreds of millions of for China, for electric vehicle etc. vehicles, such yield accounting is exactly micro- deficiency simply Road, if accounting is less than 1 percent, so in contrast, applicant is the of very good market prospects in terms of 100,000,000 users

Applicant to achieve the goals above, carried out countless trials, narrow respectively with width, the U of long three kinds of different sizes Shape lock has made sample, from use saw blade saw steel pipe originally, be really it is too slow too laborious, also there are several now newly Saw blade, to having bought two hand grinding tools, an abrasive machine, a cutting machine, an electric hand drill, various drill bits more than ten successively below Branch, hole making drill also have ten, and plain vise, hammer, riveting gun, three pliers, and ten various spanners, various screws Knife, various files, various square tubes, round tube arrive design drawing, modify repeatedly, the purchase various models of screw rod, steel pipe socket Silk etc., there are also several tanks paint and several brush etc., then to application documents are write, modification is pondered repeatedly again and again, then to application with The expense of doing subtracts proof etc., has really taken the tremendous effort, has taken countless time and efforts, present waste product material has three enough Snakeskin bag, but from the point of view of sample, purpose may be implemented completely, absolutely not be to talk about stratagems on paper.Next prepare to buy die head threading machine And tapping machine considers oneself organizing slowly if passed through, or looks for factory's joint processing, then external market pin It sells, this is a current preliminary project.
