A kind of Novel anti-theft pin tumbler lock lock core Anti-blocking device
Technical field:
The present invention relates to lock technology fields, and in particular to a kind of Novel anti-theft pin tumbler lock lock core Anti-blocking device.
Background technique:
Spring lock (Pin Tumbler Lock), also known as cylinder lock with balls, pearl lock, snap lock or pin tumbler locks, be it is one of most
Common lock structure.Principle is the cylindrical component (referred to as snap, pellet or pearl) using multiple and different height, locks lock
Core.When being put into correct key, each snap is pushed to identical height, and lock core is just released.
Existing spring lock uses various unlocking tools at this stage, can quickly be opened since structural principle is simple
It opens, being primarily due to lock core is the mode that is inserted vertically into, and unlocking tool can directly enter lock core easily, so as to cause anti-theft
Can it is poor, at this stage in order to increase spring lock anti-technical unlocking difficulty, be mostly by increase lock core complexity, but
It is that the placement of lock core is not gone to change, can be readily intercalated into lock core so as to cause unlocking tool, once unlocking tool holds
Easily in insertion lock core, by some means, it can be easy to open lock core.
Therefore the application has developed a kind of Novel anti-theft pin tumbler lock to radially distribute using multiple lock cores, and key is necessary
To switch to horizontality by vertical state could be inserted into lock core, make most of unlocking tool on the market, cannot effectively be inserted into lock
In-core greatly improves unlocking difficulty.
But the Novel anti-theft pin tumbler lock is when in use, since the spring of lower pellet bottom is larger, extracts out in key
Afterwards, lower pellet is easy that slot will be played in the pop-up of upper pellet, causes lock core to block, necrosis, thus can not be effective by the elastic force of spring
It unlocks.
Summary of the invention:

The present invention for a kind of Novel anti-theft pin tumbler lock lock core with Anti-blocking device when in use:
(1) handle block 30 is held, keeps the second adjusting block 31 on handle block 30 corresponding with the first tag block 3, by fixture block
37 alignment lockholes 22, and be inserted into lockhole 22;
(2) due to the insertion of fixture block 37, fixture block 37 pushes connecting rod 35 to shrink, while driving the synchronous recycling of fixed ring 36,
The connection sheet 33 in fixed ring 36 is moved with corresponding diversion trench 5 simultaneously, is constantly scattered outward;
(3) since handle block 30 constantly promotes, in addition the flexibility of connection sheet 33, makes connection sheet 33 with diversion trench 5
Into in corresponding keyhole 42;
(4) when connection sheet 33 is completely into keyhole 42, i.e. lock tooth 34 fastens with corresponding upper pellet 23, locks tooth
34 make pellet 23 push lower about 26 pellet flexible, when upper 23 bottom of pellet is in lock core bottom and is concordant state, that is, lock
Core 9 unlocks;
(5) when connection sheet 33 is completely into keyhole 42, connecting rod 35 is contracted to most short, 37 upper end of fixture block and snap ring
41 fasten, then swing handle block 30, drive the rotation of lock pillar 4, by the rotation of chain 21, drive the rotation of turntable 19,
It drives connecting line 48 to shrink simultaneously, shrinks lock tongue 15, lock tongue 15 is separated with card slot 7, elasticity of the lock ring 1 due to the first spring 10
Automatic spring, i.e. lock ring 1 are opened, and are unlocked and are completed;
(6) in 1 force feed of lock ring to corresponding first regulating tank 6 and the second regulating tank 14, lock tongue 15 is due to the second bullet
The elasticity of spring directly pops up lock tongue 15, fastens with card slot 7, and lock ring 1 is by lock pillar, due to the pop-up of lock tongue 15, connecting line 48
Restore initial length, drive the rotation of turntable 19, by the transmission of chain 21, rotates lock pillar 4, in addition locating piece 8, makes lock core
9 accurately restore to initial position;
(7) when connection sheet 33 is extracted, upper pellet 23 is directly popped up due to the elasticity of third spring 27, restores initial bit
It sets, enters in corresponding upper bullet slot 44 with pellet 26 at present, lock core 9 is fixed;
(8) when key 46 is extracted, due to the protrusion 12 on fixture block 37, the frictional force between engaging is increased, it being capable of band
The dynamic constantly elongation of connecting rod 35, while driving fixed ring 36 that the connection sheet 33 of umbrella is constantly carried out recycling and being fixed into cylinder
Shape restores to original state, and after connection sheet 33 is extracted completely, last fixture block 37 is separated with lockhole 22, i.e., key 46 is extracted.
