Description

A kind of anti-U-shape lock bar is cut and the anti-device for pounding and protecting lockhole in lock body both ends

Technical field

The technical field that this patent scheme is related to is the technical field of safety protection of U-shape lock tool.Specifically, it is related to A kind of protective device dedicated for preventing the locking bar of U-shape lock from being cut by hydraulic shear.

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 electric vehicle and motorcycle for locking bicycle, two-wheeled or three-wheel, and many U-shapeds for being used to lock glass door Lock.

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 of unlockings various in modern society are spread wide, the unlocking tool sold on network is also day Cumulative more, the stolen case of bicycle, two-wheeled or three-wheeled electric vehicle and motorcycle also emerges one after another, therefore urgent need is by U The security protection performance of type lock is improved, to prevent from reducing stolen caused loss in other words.

However, so far, because the locking bar of U-shape lock is thinner, thick is but difficult to, so the locking bar of U-shape lock holds very much It is subject to cut energetically or the cutting of hydraulic shear, it is also difficult to this destructive unlatching means are prevented, in the market numerous U-shape locks, In face of the hydraulic shear of confirmed thief, there's no one who doesn't or isn't so.

From the point of view of the patent of the announcement under Patent Office's E05b classification, in hundreds of items, be related to individually it is anti-cut be also Claim to cut using hard material is more anti-；Mention it is anti-pound almost without；Protection lockhole on the contrary has several, but is mostly anti- Water dust protection etc, also there are individual preventing tools, in general, A grades of lock cores are difficult to anti-technology in fact and open, side column lock It is larger with the difficulty of blade lock and the on the contrary technical unlocking of some special-shaped lockhole lock cores, but have above-mentioned several synthesis Not seeing in fact for protective performance has.

U-shape lock is illegally opened in order to prevent, and this patent, which devises, can effectively be combined with the locking bar of U-shape lock and mating can be answered Protective device, with preferably reach prevent U-shape lock by the purpose of pirate of the open (Fig. 2 and 3 is the sample made of examination and effect Figure)

Summary of the invention

This patent technical problem to be solved:

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

Technical solution used by this patent:

To solve the above-mentioned problems, this programme contemplate one the locking bar of U-shape lock sheared in terms of protection Technical solution

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, and the hydraulic shear on certain treasured sale website platform is cut It is mouthful big in 28MM, the width and thickness for the object cut if necessary is coarse enough, then being not easy to cut off can not either cut at all The locking bar of the opened traditional U-shape lock is most of all considerably long, but not coarse, and 16MM-----18MM is just quite thick, Also some 12 or 14MM's, it thus can easily be put into the clip of hydraulic shear and quickly be cut off, this is also due to tradition Locking bar by processing technology limitation, coarseer round steel be more difficult to Bending Processing molding, be also just difficult to obtain coarseer Locking bar, this patent does not need then to process coarse locking bar, but has installed a more coarse steel pipe additional on locking bar 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 It cuts off.In addition when hydraulic shear is difficult to cut, just unlikely, the sample in this programme is other manual cutting modes The steel pipe of outer diameter 32MM, it is just more much greater than locking bar.

Therefore, applicant thinks that the technical program disconnected purpose to be solved for preventing locking bar from being cut is obvious energy Enough reach, is to set up, the solution of this problem is also open-and-shut, and the being readily appreciated that

It will be not easy to cut using the U-shape lock bar of this protective device, if cutting machine, sound is very big, is sawed with saw, no It can manage it for the moment.

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

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, Fig. 2 is only one of the component 1 preliminary photo processed substantially, be in order to more intuitively show, It is picture in kind, as aid illustration.

The present apparatus mainly includes following 4 components: (due to having no such device before, so component names have to basis Component shape or function and effect etc. are named)

Component 1: " one section of two end Dou Chong has a small U-shaped breach and the whole thick steel pipe for being converted into U-shaped ", it is special Point:

(1), total length is more shorter than the locking bar overall length that U-shaped is locked, the U being similarly also converted into bending machine as locking bar Shape is to roll over simultaneously with locking bar, covers outside locking bar that here, component 1 is such as both to have worn one layer to the periphery of locking bar Protective garment is the same；

(2), diameter 32MM, the diameter of the locking bar much larger than 16MM are twice of locking bar, and are significantly greater than common Hydraulic shear clip (28MM)；

(3), specific form: on the surface close to two locking bar end 10MM of this U-shaped steel pipe, each is also all cut above There is a small U-shaped breach, which is only slightly wider than lock body, by taking the lock body of 22MM wide as an example, gap width 24MM, every side The leeway of major 1MM just, only allows lock body both ends insertion portion to allow if wanting strike lock body both ends if there is external force in this way If lock tongue and locking bar are detached from, it can be encased by the end of component 1, beat the end less than lock body, the lock for making lock body will not be generated The power for the both direction that tongue is separated with locking bar also just plays the role of anti-cut simultaneously and beats with anti-pound in part.

Component 2: " 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 2 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, load onto component 3,4 stamp rivet it Afterwards, the lockhole on the lockhole and lock body on this component has been separated a bit of spacing, small pin for the case when making skilled unlocking to Still it leans against on lock core side better other requirement and improves very much, the thrust for the arm that Yao Gaicheng is poised, along with lock exists in lock After 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, the height of eye The factors such as the limitation of degree and position are wanted the shape for detecting lock core or are further speculated after the reinforcement protection for having this component The structure for judging lock core, such as touches lockhole with finger, touch less than, in this way, think direct detection to lockhole and lock core form Words, condition and require can it is higher, lock lock on wheel after, do not exceed the knee of human body highly, i.e., be usually not above from The height that 50 centimeters of ground, and the sight of human eye will not turn round, be difficult to see squatting down and using light searchlighting and 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 skilled unlocking is just if lock core form It does not know where to begin, and the owner locked has key, and is the form of known lock and lock core, unlocking is between the two without laborious There is significant difference to rivet upper two small L shape iron plate components 3,4 on the rivet hole of this component, further to block from both ends Observe the sight of engagement mechanism.

Component 3,4: being " two fritter L shape steel plates ", it is characterized in that:

Shape is similar to angle bar, and the height of lock body is highly subtracted for the interior height of component 2, and width is slightly less than the inner width of component 2, And be provided with a rivet hole H3 on the narrow side of component 3, be provided with hole H4 on component 4, in order to the rivet hole on component 2 H1, H2 are connected by rivet；

Effect has two o'clock: 1) for the both ends of packaged unit 2 " short rectangular steel tube " after being packed into lock body, making the illegal skill person of opening The form and construction of lockhole can not be seen from any end；

2) for strut component 2 it is with holes while with have on lock body lockhole while spacing, for use when anti-skill is opened It is bad when small pin for the case to directly bear against on lockhole not, it can only vacantly go to push the difficulty for not improving that hand manipulates tool when skill is opened, reduce A possibility that being opened by skill.

The schematic illustration of attached drawing 1 are as follows:

Fig. 1 is total component structural schematic diagram；

Fig. 2 is the schematic diagram after only components 1 and the processing of U-shape lock bar with the mating displaying of lock body；

Fig. 3 is the schematic diagram in kind of all components.

The beneficial effect of this patent is:

Have the advantages that significantly to prevent U-shape lock locking bar from being cut, also therefore to the theoretical knowledge and material object of relevant range The expansion of directionality has been made in the research and development of device or the product of application, and it is bright also to have safety guard for U-shape lock from now on The really field of new research and development and range.

The locking bar of U-shape lock can be protected not cut, played a very good protection to preventing trouble before it happens, this is complete certainly It is determined according to actual needs to select the degree of protection of product depending on user.Also can not be had by the U-shape lock of pirate of the open to develop in the future Certain basis is laid.

Specifically, it will be impossible for cutting manually after U-shape lock has this to reinforce protective device.

And the end of lock body can be allowed to enter since the both ends of U-shaped steel pipe are provided with small U-shaped breach, effectively prevent from The method that lockhole position carries out the effectively function of strike damage lock to lock body.

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 for preventing small-sized two-wheel and three-wheeled vehicle safety, after being widely used It will can reduce the situation that takes place frequently of burglar.Perhaps it can become the standard configuration of U-shaped lock after, it is best if it can become national standard.

Shortcoming is that, because the present apparatus is all metal steel construction, steel have certain weight, quick for portable weight The user of sense may feel some inconvenience, only more pay attention to the safety of bicycle and two-wheeled or three-wheeled electric vehicle and motorcycle Client can gladly select, so also need to allow client to understand correlated performance in popularization and application, also have one it is longer when Between period only applicant believes that, this product be easy to for user receive other than its practicability, Another reason is it Material cost it is cheap, for the sample manufactured by the applicant, if being calculated with present price currently on the market, material at This market price is acceptable, and sample is substantially worked it out for cost performance less than 15 yuan.
