Description

A kind of isolated anti-theft lock structure

Technical field

The present invention relates to a kind of isolated anti-theft lock structure, belong to five metals lock technology field.

Background technology

Theftproof lock is that everybody be unable to do without, almost daily all in the important device using.Based on practical, cheap, convenient, The reason such as durable, mechanical antitheft lock is all the time in occupation of absolute market.Although through generation by generation, the technology of an another item Improve, its safety is still very fragile.To illustrate that prior art exists below great taking modal spring lock as a example Problem, analyzes the reason fail radical cure problem all the time.

Spring lock is that the pellet in extruding lock core is so as to all arrive at using length on the key or the concavo-convex shape differing Suitable position, is no longer prevented from the rotation of lock core and realizes unlocking.After key is extracted, pellet is bounce back into raw bits by spring again Put, again stop the rotation of lock core from realizing locking.The lock construction of this opening and closing mode, the moment key being doomed to open is not Can extract, and key and pellet must be in close contact.This " contact " creates inborn pirate of the open to unlocking tool Condition, makes it have an opportunity tentative mobile pellet, imitates out correct key information and open lock, so we claim prior art Lock for contact lock.The complexity although lock core of contact lock and Key structure are constantly innovated or upgraded, is merely able to increase The difficulty imitated, thus extending the time of pirate of the open, but can not fundamentally prevent by the problem of pirate of the open.The situation of practical application is, , special pirate of the open method and special in super only three months of contact lock every kind of New Product listing after will being disassembled research Pirate of the open instrument, occurred in that now the pirate of the open instrument of intelligent detecting, cracked speed quicker.In sum, existing Lockmaking technology cannot fundamentally solve the problems, such as by pirate of the open, and reason is exactly to lock effective start-up time it is impossible to exclude instrument Contact the essential condition of this pirate of the open with lock core, this is the significant deficiency of existing lockmaking technology.

Contact lockmaking technology becomes increasingly complex with lock core, manufactures also more and more accurate.Need between each parts closely Combination, major part carries pressure duty under the action of the spring, and this just inevitably exacerbates the abrasion of device.Using a timing Between arise that loose frame between parts, or even stay key to use vestige to burglar, anti-theft capability will be deteriorated.In addition also can contract , the problems such as motility and be deteriorated in short service life.It is usual thing that the normal lock using changes time lock core for 1 year, warp in life It is commonly seen to the new lock filling lubricating oil in 1 year or lead（Pen core）Not not the opening lock it is also possible to oneself key occurs at any time of powder Situation, increased use cost to user and brings many troubles, this is also the unavoidable defect of existing lockmaking technology.

Above-mentioned disadvantage is insurmountable problem under existing lockmaking know-why, in the face of hard to guard against advanced pirate of the open technology With the unlocking tool of modernization, then continue to use existing anti theft design thinking, contact lock construction of innovating simply or upgrade has not had There is too big meaning it is necessary to thoroughly change existing lockmaking principle, this, by the essential condition of pirate of the open, invents series to exclude " contact " Novel antitheft lock, the difficult problem that ability effectively solving background technology exists.
