Technical field
The utility model belongs to the vehicle lock technical field, is specifically related to a kind of Pickproof lock for vehicle, is applied on the vehicle of motorcycle, battery truck, pedicab and even bicycle and so on.
Background technology
Stolen for fear of aforesaid vehicle, usually except the lockset that on car body, carries, also additionally add and join various lockset such as ring lock, inserted link lock and various alarming locks or the like, but facts have proved that this setting up defences only is a kind of psychological self confort, can not really play the anti-theft effect that the phase of making us gets, need not to scruple and fear at all in the effect of present lock because steal the person.Keep an eye on stopping (pool) special messenger that assign in the parking lot with compensation, can yet be regarded as is a kind ofly can avoid or reduce the stolen useful act of vehicle effectively, can be seen in from the disclosed technical scheme that can prevent the parking apparatus that vehicle is stolen of Chinese utility model patent ZL200520076211.X this.But, the place of parking that the special messenger keeps an eye on only is suitable for some specific place such as busy street, market, supermarket, large-scale public place, hotel and wineshop etc., and the common situations that do not exist the special messenger to keep an eye on such as more place such as common neighbour, road, shop, residential district, therefore, stolen probability is very high.
Reason as known to the public because vehicle stolen becomes big public hazards of society, so people to satirize auto theft person be the fifth-largest public hazards outside the four big public hazards (mouse, cockroach, fly and mosquito).In view of this, China Ministry of Public Security has assigned the first half of the year in 2007 and has carried out the stolen instruction of regulation public vehicles in China, each provinces, municipalities and autonomous regions speed is promptly tackled (response), received gratifying effect, society's repercussion is good, the mistake yet the regulation as the violent storm is taken action, auto theft person relapses into one's old bad habit again, even more rampant.
The information that obtains from medium and public security department shows that causing the stolen main cause of vehicle is that theftproof lock falls short of the reality, and more particularly, many theftproof locks are just as deaf person's ear, belongs to deceiving oneself and defraud people's pendulum-type not.The knowledgeable people has constantly innovated various theftproof locks, can be seen in a large number in Chinese patent literature this, sorts out to mainly contain following four classes: the one, and pure mechanical anti-theft lock; The 2nd, the pure cipher theftproof lock; The 3rd, the mechanical theftproof lock that has both mutually with password; The 4th, mechanical lock adds warning device, coded lock adds warning device or mechanical lock adds warning device again with combining of coded lock.Be seen at present in the theftproof lock in market and account for absolute leading position by the lock of above-mentioned four classes too, but mechanical lock accounts for more than 95% in four class theftproof locks, this is because mechanical lock has terse, the easy to operate and low-cost advantage of structure.Because, the password of coded lock was set in advance before going on the market by the lockset production unit usually, both be not easy to change arbitrarily with car owner's hope, be unfavorable for again engraving on one's mind, again because the lock of warning function is subjected to the influence of distance and environment usually, for example, when the car owner is outside tens meters or hundred meters on vehicle, even if it is also of no avail to report to the police, and for example when surrounding environment was noisy, even report to the police, the car owner also can't examine and know, moreover the weatherability extreme difference of warning device and fault rate height promptly can lose function as in a single day meeting with and tanning by the sun or drench with rain.
But, can not deny that mechanical lock also has the aspect of its shortcoming, the person sets about as the breach to lock core easily for example to steal the car, through the applicant's long-term observation, the structure that is applied to the theftproof lock that belongs to the mechanical lock category on the aforementioned vehicle in the prior art is unreasonable, be embodied in: lock core has no the ground of coverage and is exposed to outside the lock body, the person sets about very to help stealing the car, can be confirmed by the disclosed Clothoid type U of Chinese utility model patent notice of authorization CN2802011Y type inserted link warning lock to this, although this patent scheme is furnished with warning device.
In sum, the applicant thinks and is necessary that the structure to the theftproof lock in the prior art is improved, and causes damage to the car owner avoiding effectively.
