Description
One. technical field:
The utility model relates to a kind of anti-poking lock, particularly relates to a kind of composite spring type anti-poking lock that need not key.
Two. background technology:
For the safety that protects one's own property; people often place hope on lockset; the mechanical lock of Xiao Shouing in the market; different modeling, various in style, the shape of key have " one " word, and " U " shape is arranged; " ten " word is arranged; the filled circles column is arranged, have hollow columned, have crescent shape or the like.But one of important means of robber's crime also is to start with from lockset:
The one, by prize, pound, turn round, pull out, means such as brill destroy lockset because this method needs bigger tool used in crime, its target is big, and sound of movement is big, so the offender does not generally use.
The 2nd, the omnipotent awl of the similar key shape of making of high-strength metal material inserts rotation by force after the conventional lock cylinders, the pellet shot from a slingshot of this moment is cut just as the material in the plate shearing machine can't bear one, lock not open all not all right, the speed of unblanking is not at all than original key inferior (thief answers police's question---open 1 about 10 seconds), it is multifarious why people can see, the key of different modeling, wishing does not exactly also have the cone consistent with its shape in thief's the omnipotent awl, car of some people is joined many lock of different key shape, also be nothing but to feel this point point by sheer good luck, this unlocking tool is very small and exquisite, can be contained in the pocket of clothes and be not found, also without any need for skill, thereby often used when unblanking by the offender.
The 3rd, unblank by the so-called master key of self so-called technology and autogamy, mostly be rotational structure greatly between lock core and the lock body at present, because the existence of machining error, it is poor to produce certain included angle when making two circles tangent, the existence of this angle difference, cause and can carry out changing joint to one by one pellet shot from a slingshot with foreign matter not as good as the tangent profound son of resistance, thus on tangent round core face the profound sub line of formation, make pellet shot from a slingshot out of control and unblank.In addition, existing lock core generally all is to rotate to a direction, and the torsional forces when master worker that unblanks (company of unblanking) and offender rotate according to so-called master key is judged the position and the quantity of pellet shot from a slingshot, thereby opens lockset, makes lockset ineffective.Because this method is more hidden, be not easy to be found, therefore also often used by the offender.
At these situations, people strengthen the intensity and the fastness of lockset on the one hand, change the mode of unblanking on the other hand, thereby reach the purpose of the defending performance that improves lock, as: the lock core parallel-moving type theftproof lock that key does not rotate, existing these locksets bring great injury for people's spirit and economy because the deficiency of design and manufacturing all can not fundamentally solve lockset by the deficiency of pirate of the open.

The anti-tongue of disclosing on the described composite pellet is that awl is trapezoidal.
The beneficial effects of the utility model:
1. the utility model is novel in design unique, adopts brand-new structure and opening ways, just because of these essential change that takes place on the internal core structure, thereby has obtained qualitative leap on performance.No longer need the turn key when unblanking, can't rotate, be different from the mode that existing conventional lock needs the turn key unlocking fully even a key is twisted into two parts also.Design is not only in order to save the simple motion of turn key like this, and main is for antitheft! Because novel lockset does not just design rotatable mechanism, those so-called " omnipotent awls " just can't open lockset.It is enough in a kind of moulding so the key of this lockset need not be multifarious as the key of existing conventional lock! Even if used multiple moulding, also no longer be in order to take precautions against " omnipotent awl ", to use but distinguish for convenience.
2. anti-effective, the breakthrough composite pellet overall structure of pirate of the open of the utility model is different from the understanding of people to conventional lock pellet shot from a slingshot (trifling and lonely cylinder) fully.Unblank to start tongue and pass from the composite pellet center, unblanking to start tongue can be by the trapezoidal anti-tongue bidirectional locking of disclosing of the awl of composite pellet, and promptly two awls are trapezoidal anti-ly discloses tongue and be synchronized with the movement, and can insert to pin in the corresponding aperture of unblanking to start tongue and unblank to start tongue.Anti-on the composite pellet disclosed design---and bore and trapezoidally anti-ly disclose tongue, to be not only in order inserting easily and to unblank to start in the corresponding aperture of tongue, importantly it can be in case disclose.In fact, owing to there is the odjective cause of machining accuracy, under the locking state, although bore and trapezoidally anti-disclose tongue and all unblanking to start in the corresponding aperture of tongue, they can not touch hole wall simultaneously, contact and do not contact, have and do not have the difference of frictional force, perhaps this difference is very little, is designed to bore trapezoidal tongue, just can prevent this a shade of difference of master worker's perception of unblanking that those are clever.Its operating principle is exactly: even disclose out touching, allow other tongue touch, because tongue is that awl is trapezoidal, still the accuracy that can't determine to disclose distance of before disclosing out, may be just in time, may be not enough, may surpass, wherein just in time have only one (unblanking), not enough and surpass (all lockings) and but have numerous.So the result who discloses will inevitably be absorbed among the cycle of disorderly disclosing, not once disclose reference value on be of practical significance.Thus, the non-matching key possibility of unblanking is just near zero.
3, the utility model does not have by means of power, indifference design, makes that illegally unblanking not have mark can seek, and theftproof performance is further strengthened.The nothing power of borrowing refers to unblanks to start tongue indirect and external relation such as lock ring draw-in groove and the button of locking.Indifference refers under the locking state, not only composite pellet appearance and size, weight and movably ultimate range is identical, and the length of composite pellet spring is all identical with elastic force, simultaneously, to enter in the key chamber length also identical, so how identical for composite pellet, also be to disclose in order further to prevent, it makes illegally discloses the lock person seeks the effort of leak by promoting composite pellet, has become futile effort, and the clever again person that illegally do not unblank also can't seek originally with regard to non-existent difference from these are identical.
4. the utility model is fit to large-scale production; this lockset is than the easier processing of existing conventional lock; existing conventional lock lock core mostly uses the cast iron framework, and the casting process complexity wastes time and energy; also there is problem of environmental pollution; the lock core of this novel lockset does not use foundry goods, and whole process does not have environment pollution, and it adopts modern numerical control device to carry out automation or semi-automatic processing; the machining accuracy height, and ensure the quality of products easily.
5, the utility model is an example with lock structure shown in the drawings, is knowing under the key bit sign indicating number situation of (forming such as the tooth value sized-multiple fixing by 8), and the theory probability of unblanking is 1 (promptly 1/1 of 8 10 power branches, 073,741,824 surpass 1,/10 100,000,000 7 thousand ten thousand), almost nil.Conversely, if do not know the tooth sign indicating number of key, just more be difficult to apply, thereby it is safe.In the practical operation, according to the use occasion of lock, also can adopt half of lock core structure, its theoretical safety then is 1 (promptly 1/32768) of 85 power branches, and is quite safe equally.
6. the utility model scope of application is wide, this lockset cosmetic variation is little, wide adaptability can be applied in the middle of the existing various field basically, such as: the padlock of lock for motorcycle, electronic lock, bicycle lock, glass door lock, house lead in door lock and chain lock and traditional design etc.; The selling market is wide, after the popularization, has good society and economic benefit.
