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, the important device almost all used every day.Based on the reason such as practical, cheap, convenient, durable, mechanical antitheft lock is all the time in occupation of absolute market.Although through generation by generation, the technological improvement of an another item, its safety fragility very.For modal cylinder lock, the significant problem that prior art exists is described below, analyzes and fail the reason of radical cure problem all the time.

Cylinder lock utilizes length or the concavo-convex shape differed on the key, the pellet in extruding lock core, makes it all arrive the position be applicable to, no longer stop the rotation of lock core and realize unblanking.After key is extracted, pellet is bounce back into home position by spring again, again stops the rotation of lock core and realizes locking.The lock construction of this opening and closing mode, the moment key of being doomed to open can not be extracted, and key and pellet must be close contacts.This " contact " creates inborn pirate of the open condition to unlocking tool, makes it have an opportunity tentative mobile pellet, imitates out correct key information and opened by lock, so we claim prior art to lock for contact lock.Although the lock core of contact lock and Key structure are constantly innovated or complexity of upgrading, be merely able to increase the difficulty of imitation thus the time of prolongation pirate of the open, but can not fundamentally stop by the problem of pirate of the open.The situation of practical application is, super only three months of contact lock often kind of New Product listing, occurs special pirate of the open method and special pirate of the open instrument after will being disassembled research, occurred now the pirate of the open instrument of intelligent detecting, cracked speed quicker.In sum, existing lockmaking technology cannot fundamentally solve by pirate of the open problem, and reason is exactly that cannot get rid of instrument contacts this pirate of the open necessary condition with lock core, this is the significant deficiency of existing lockmaking technology at the effective start-up time of lock.

Contact lockmaking technology becomes increasingly complex along with lock core, manufactures also more and more accurate.Need between each parts to combine closely, major part is with pressure duty under the action of the spring, and this just inevitably exacerbates the wearing and tearing of device.Use certain hour just there will be the loose frame between parts, and even leave key to burglar and use vestige, anti-theft capability will be deteriorated.In addition also can reduction of service life, there is the problems such as flexibility variation.It is usual thing that the lock of normal use changes time lock core for 1 year, often see to the new lock charging-up lubricant oil in a year or lead (pen core) powder in life, also may occur at any time oneself key do not open lock situation, add use cost to user and bring 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 and modern unlocking tool, continue to use existing anti theft design thinking again, innovate simply or contact lock construction not too large meaning of upgrading, thoroughly must change existing lockmaking principle, get rid of " contact " this by the necessary condition of pirate of the open, invention Novel series lock, could effectively solve background technology existence a difficult problem.

Summary of the invention

The object of the invention is to provide a kind of isolated anti-theft lock structure, adopts noncontact opening technology, by key and lock core isolation when unblanking, solves the problems referred to above that background technology exists.

7, integrated key

Because key of the present invention is smaller and more exquisite, do not need again rotate, can be very easy to by many, lock key be overlayed in a box, need with which time, its release can be used.Also can 4 propelling side's bars be placed in special handle, need with which key time, promote or the corresponding button of turn allow propelling side's bar telescopic variation go out this key shape.

work period of the present invention:

1, blocking.Slider is all returned in lock core, and all slider grooves are messy position, and stop valve is away from slider, and variable key passage is that scissor-shaped dislocation is in complete closure state.To direction swing handle of unblanking through anchor point, again close after variable key passage elder generation is through, stop valve is exposed to outside lock core because not entering slider groove, all transmissions are made to be stuck and to stop action, the locking bolt overwhelming majority is still stretched out and is in blocking, and now anything cannot enter variable key passage;

2, preset information of unblanking.To counter-rotation handle, stop valve is gradually away from slider, and when positioner prompting location, variable key passage is breakthrough status.If one direction can not find anchor point, can at left-right rotation handle among a small circle, until feel location time, insert key and promote slider, all slider grooves are preset to lockset position of coupler.Now key prevents the scissor motion of variable key passage, and what make all transmissions cannot do unlocking action;

3, to unblank process.Extract the backward direction swing handle of unblanking of key, after variable key passage is closed, stop valve can enter slider groove and all in retraction lock core, remove the stopping function to all transmissions, is rotated further handle and locking bolt is all retracted realization and unblank.In whole process of effectively unblanking, keyhole is closed all the time, and any instrument all cannot enter in lock;

4, return locking.To the continuous swing handle in locking direction, shift out successively through stop valve from slider groove, positioner is located, and key overall channel is through, and return inclined-plane makes slider all be returned in lock core, gets back to blocking described in the 1st step and completes a work period.Pressing mode return, directly press during location and make slider return.If want before slider return that cancelling locking unblanks again, need not insert key again and directly repeat step 3.

the antitheft principle of the present invention:

1, because variable key passage is made up of STATEMENT OF FEDERALLY SPONSORED segmentation, when any pirate of the open instrument enters variable key passage, itself become the prevention thing that passage does scissors closed action, each section of variable key passage can not move, thus makes full lock not carry out switching manipulation.Want opened lock just necessary puller, want to plug in instrument just impossible opened lock.The two conditions each other, and synchronization only completes a kind of antitheft principle of action, allows the pirate of the open method of the tentative unlatching of all insertion tools thoroughly lose efficacy;

2, insert pirate of the open instrument time stop valve away from slider, promotion slider moves and does not have any touching sensation, cannot the tram information of perception slider, can only survey by guess to pre-set slider position, treat that can the removable stop valve in puller rear go the checking of contact slider unblank.This process of unblanking is carried out stage by stage, in other words the indirect type antitheft principle of unblanking, and the unique method leaving burglar for surveys pirate of the open by guess;

3, at effective start-up time of isolation lock, variable key passage closes completely, all parts complete unlocking action in environment in closing, cannot see, hear and touch the operating condition of all devices in lock from the outside, current all technological means all cannot realize detection and control to locking interior situation.This totally enclosed principle of unblanking in the moment of effectively unblanking, any pirate of the open instrument all can only be heaved a sigh at lock outer prestige lock;

4, the low-pressure wiping design of isolation lock is applicable to full rigid material manufacture, and hard material and lock core not exposed structure are effectively resisted dismounting and destroyed.Destroy for a long time once experience high strength instrument, full lock paralysis can be caused locked, can not re-use and more can not open again.This type self-destroyed antitheft principle, adds last pipe protection to the isolation lock cannot opened by technological means.

The invention has the beneficial effects as follows: key must be extracted and just can unblank, the breakthrough structure that pirate of the open instrument is thoroughly isolated, achieving anti-theft technique by increasing opening difficulty to the qualitative leap of stopping pirate of the open.Preset information of unblanking, alterable keyhole and noncontact such as to open indirectly at the revolutionary technology all belonging to theftproof lock industry and update.

Technical characterstic:

1, full separate piece production line standardized production, makes theftproof lock manufacture become very simple;

2, sale is made in naked locking, and user installs slider encryption voluntarily, and can realize delivering after network remote monitors production and user's Remote seal;

3, the slider coded message of user, the dedicated network management that can be stored in public security management is for subsequent use;

4, parts run without the low wearing and tearing of pressure, need not safeguard throughout one's life;

5, key accessible site is one, removes the worry of carrying a large amount of key;

6, many spoons, a lock, realizes collective easily and unblanks;

7, full rigid material and do not expose cylinder design and effectively resist malicious sabotage.
