Description

The letter structure is prohibited robber's lock and key thereof

Technical field

The present invention relates to a kind of lockset, especially a kind of lock core structure is simple and have the simple structure of wiping out robber's function and prohibit and steal lock and key thereof.

Background technology

Lockset is that the anti theft design concept rules all the land since the dawn of human civilization all the time, and the rule that the anti theft design concept has become the crowd to keep are never opened up and wiped out the burglar and win.Maintain the lockset product of common people's life, property safety, unsatisfactory can be found everywhere for this reason.Lockset design circle, manufacturing industry are said " instrument may occur never without the lock of separating forever ".The occupation locksmith says " lock in the world is as long as key can be opened, and instrument just can be opened, and just instrument cracks time length difference ".The common people say " theftproof lock is non-anti-theft ", " lock is the not anti-person of low position of only anti-gentleman ".A kind of innovation is locked the city soon in the reality, corresponding unlocking tool just goes out thereupon, unblank the master-hand to many new, old lockset technical unlockings all to calculate second, the tool technique unlatching is drawn key unlocking than owner and has also been become soon ordinary affair, connecting many world name lock (belonging to the anti theft design concept) all can crack with unlocking tool, this is fact clear to all, prohibit the lockset inventor who steals design concept as pursue always, I recognize this reality, but do not recognize above-mentioned false reasoning, simple structure is prohibited robber's lock and is namely belonged to the lock that instrument can't technically crack forever.Also have a partially opinion on the lock circle: " increase the difficulty of lockset technical unlocking, its core texture is complicated undoubtedly " become a common recognition definitely already in lockset design circle, manufacturing industry with in professional locksmith encloses.For this reason, the lockset design is walked far away and far away on complicated road.Yet complexity is not brought lockset core quality into tidemark---prohibit and steal.The world name lock Mei Digao lock of the U.S., core texture is very complicated, exquisite, connects the rotation that pellet can both be made different angles, but or can be by technical unlocking, and multiple crack method is arranged.For a long time, lockset does not reverse unsatisfactory situation with having essence, going into seriously its reason is because fatal common fault is being left in the lockset design all the time: one, industry essence is not seen clearly at all by lockset manufacturing enterprise, the top scholar Lang Xianping of business administration brilliantly sets forth: enterprise is most important not to be brand, technology, team ... first importantly sees clearly industry essence, the brand of only under this prerequisite, pursuing being outstanding, core technology, team spirit ... just first-class enterprise might be createed, just first-class product can be produced.What is the industry essence of lockset? be prohibit to steal rather than antitheft, the common people have a lingering fear already to theftproof lock is hard to guard against, wipe out the robber and are only that people dream of.Lockset manufacturer defends tenaciously the anti theft design concept all the time, how can step into the culture of tidemark lock---prohibit and steal lock? the 2nd, because the anti theft design concept, all there is mortal wound in its Design Mode, keyhole is in the pellet root and all leaves larger space, crack the operation leeway that provides enough to instrument, the 3rd, the lockset design complicated road of going on along, and become increasingly complex, the mechanism of technical unlocking is not taken out fully among the complexity, core texture is more complicated like this, and the method for technical unlocking is also more.In addition because some lockset inside is too complicated, the tapered end remaining very thin body only as a result, seem be highly brittle a little less than; Four, since the concept of lockset design location defend tenaciously antitheft, the crime time that just prolongs the robber of pursuing simply, such theory just has been doomed the mechanism of technical unlocking and has been existed.Also have two external factors: lack a mechanism that exchanges information between＜1〉lockset manufacturing enterprise and the professional locksmith, the locksmith is called and finds the lockset drawback, the forward position sentry of weak link, it is very clear that the robber leaves over the crime scene deadly defect locksmith who exposes, the locksmith is to this nothing to be surprised at, yet is provided with the feedback to lockset manufacturing enterprise without any channel, and the lockset relevant enterprise is opinionated, make a cart behind closed doors, mortal wound is still prolonged for a long time and is deposited;＜2〉authoritative institution of lockset detection is low to the industry standard Ding Detai of lockset, the standard A level lock of the anti-technical unlocking of the theftproof lock that the Ministry of Public Security promulgates a minute, B level lock 5 minutes, this substandard is followed by lockset enterprise, must cause low-quality ubiquity, and permanent continuity.State ministry of public security in 2005 has been promulgated that " machinery prohibit steal the lock examination criteria " this simple structure is prohibited and has been stolen lock and follow just this new standard to arise at the historic moment, gone back the original intention of man invented lockset---opens different locks with different keys.Yet the Ministry of Public Security promulgates that previously theftproof lock detects substandard and do not abolish, and many locksets enterprise follows is still substandard, and shows off whereby " it is qualified to detect by the Ministry of Public Security ", continues the flicker common people.

Some are also arranged based on prohibiting the product of stealing concept in the prior art, be that to steal lock and the patent No. be that 201020282896.4 simple structure is prohibited robber's lock key device for 201020282894.5 taboo such as the patent No. of application before the applicant, because the taboo of application is stolen comparatively complexity of lock construction before, the production cost is higher, be unfavorable for promoting the use of, and the consideration inspiration is collided and is done first key reservation, and front patent belongs to imperfect design case.
