The caused compared with prior art beneficial effect of the present invention is：
First, conventional lock cylinders are simple in construction opens rate height again, and easily two or more keys of cause also easily cause with a phenomenon is opened
Criminal will be locked using the blind extraction of root to open.
The anti-theft lock, by pellet duplex, placed side by side, is such as schemed, than traditional marble amount most by setting Special-shaped marble
More lock core more 60%.By pellet interval, divide Column Layout, such as scheme so that pellet long stroke is twice of conventional lock cylinders.Knot
Structure is ingenious, pellet is more, pellet stroke is big so that this lock core opens rate as little as 1/25.6th hundred million hundred million again, is certain traditional advanced lock core 1
1000 millionth 16,000,000,000 times.Even if all doors all use this lock core on the earth, also one is opened in the absence of two keys are same
Door, because in the world just without 2,500,000,000 hundred million fan antitheft doors.
2nd, traditional anti-theft lock core is single due to constructing, at all can not thorough anti-technology unlocking.No matter A levels or B levels lock
Core, anti-theft function is played only for ordinary person, and for vast unlocking company personnel and more criminals, as long as having
Time enough, the lock just do not opened.
The anti-theft lock is by multiple rows of two-way Special-shaped marble, arranged crosswise and installs timer additional, as illustrated, will termination
Technology unlocking, technology for eliminating are unlocked to family and the social potential safety hazard brought.
Multiple rows of two-way Special-shaped marble and arranged crosswise method so that the unlocking tool of criminal can not adapt to this lock core, no
All pellets can be stirred simultaneously, so safe-guard door lock cannot be opened.
The examination of criminal is missed uncaging time by the timer below lock core, is limited within 10~20 seconds.Such as figure, locking
There is a keyhole lid in core protection cap, it is necessary to when unlocking, thread escutcheon is pushed aside, thread escutcheon drives timer driving lever to rotate, and will limit
When device depress, timer crescent fork disengage clutch fork, now insert key, withstand torsion spring and push away 3 millimeters inward, clutch fork is just
Core and shift fork are linked together, it is that shift fork and then rotates together to rotate key, door-lock opening.
Push thread escutcheon aside, timer is depressed, on earth after in the presence of the main cylinder internal pressure of timer, start return.If
It is not key unlocking, but is unlocked using various instruments, timer playbacks after 20 seconds, and the clutch fork of core will be by timer
Crescent fork blocks, it is impossible to shift fork is inserted, it is overtime due to unlocking even if at this time each pellet is struck to correct position,
Clutch fork is blocked to insert by timer limitation does not enter shift fork, and this lock will not also be opened.In fact the 25.6 hundred million of this lock core marble
Hundred million kinds of combinations, a people one day do not stop, not had a rest, it is necessary to which 24,300,000,000 years could all try within 365 days 1 year for 8 hours.
3rd, traditional anti-theft lock core is easily unlocked instrument strength torsion and opened, and is also easily bored and opens by electric drill.Reason is that pellet is to use
To block the core of lock core, core is directly connected to shift fork, and when core, which runs into strength, to be reversed, pellet is just bad by torsion, therewith
Core is just rotated, and so as to drive shift fork to rotate, door lock is opened.In addition traditional anti-theft lock core is easily bored by electric drill and opened,
Be because core blocked with pellet, when electric drill bore core when, it is easy to put forth effort, core be easily drilled it is bad, so traditional anti-theft door
Lock core is easily bored by electric drill and opened.
The anti-theft lock is provided with a clutch fork between core and shift fork, and pellet is used for blocking clutch fork rather than card
Core.Such as figure, clutch fork is separated with shift fork, and core can be rotated arbitrarily, and but concomitant rotation, door lock will not be opened shift fork.
So when criminal's strength reverses core or bores core with electric drill, core concomitant rotation, powerful torsion is laid down, so as to
Core and lock core are protected, but because clutch fork is not inserted into shift fork, shift fork does not follow core to turn, so just not opening this yet
Lock.
4th, traditional anti-theft lock core can not effectively pick-proof, protecting against shock.Anti-theft door lock cylinder is inside and outside at present, and two parts connect
It is very thin to meet place, also there was only one in the bolt on door lock for fixed lock core, it is clear that impacted energetically or pull sled, lock core
Be easy to be broken from centre it is disconnected, or from locking directly to prizing, so that door lock is opened easily.
The anti-theft lock center section is widened to 1.7 times of existing lock core, intensity is increased several times, the additional protection of lock core
Lid, such as scheme, then protective cover be bolted on antitheft door with multiple, so attempt destruction lock core, the sled of application, pull and its
He is blocked or laid down by protective jacket impulsive force, so as to protect lock core, strengthens the pick-proof of this lock core, shoulders the antitheft energy of impact
Power.
5th, traditional anti-theft door interlock switch bothers, and insertion key stirs two section dead bolts and spring latch, must rotate key 720+
110=830 degree.If had on key ring, more keys and nail clipper, fruit knife etc. are small scrappy, and rotation takes two turns more and middle
Need twice hand could unlock, people can be allowed to feel pretty troublesome.
The anti-theft lock is improved this, shift fork is changed to trident by current single tine so that effect of locking and unlock
Rate improve it is nearly completing above-mentioned unlocking action twice more, locking only needs that only 150 degree of key need to be rotated, less than half-turn,（Market
Lock is required to 720 degree, two circles）.Unlocking only needs to rotate 220 degree of key, and half-turn is more,（Traditional locks need 830 degree, two circles
Half）.This lock core is locked, unlocked, it is only necessary to rotates key half-turn or so, it is not necessary to is changed hands and is turned key, accomplishs without any letup, very just
Profit.
The anti-theft lock is reasonable in design, simple in construction, safe and reliable, easy to use, easy to maintain, has and promotes well
Use value.
