Description
Technical field
The present invention relates to one kind lock, in particular, it is related to a kind of AB locks.
Background technology
So-called AB locks and AB keys are exactly that a lock core may be inserted into two kinds of keys of A, B, and A keys are only used as engineering key,
Grasped for building before being delivered for use by workmen, B keys are grasped by owner, when Practical Completion is delivered for use, owner
After with B keys, the lock is opened, AB functions have been changed, and A keys are not just opened again the lock, have filled such lock, and owner is just not
With changing lockset for safety.
Most of key of AB of the prior art lock is an A keys hole or many breach more than B key,
After AB power and energies, it can be unlocked if mending by the hole of A keys or breach with foreign matter, in addition, by A key deallocations
One B keys are also easy, as long as processing a hole or breach less, it is just the same with B keys, and this there are in fact pole
Big potential safety hazard.
The content of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of AB locks.
What the present invention was realized in：Including lock body, lock core, A blades and B blades, lock pin, A keys key and B keys, institute
State lock core and be provided with some blade grooves vertically, built-in A blades and B blades, the A blades and B blades are provided with unlocking groove,
Lock core is longitudinally provided with lock pin groove perpendicular to blade groove, and built-in lock pin is provided with locator card in the front end or rear end of lock pin groove, described
The front end or rear end of lock pin are provided with location hook, and lock pin is provided with several avoiding hollow grooves, and before AB power and energies, avoiding hollow groove aligns B
Blade, after AB power and energies, avoiding hollow groove displacement is no longer aligned with B blades, and the lock body, which corresponds at lock pin, is provided with lock slots,
It is provided with lock body relevant position and pushes or pull on magnetic patch or spring that lock pin carries out AB power and energies, the A keys corresponds to
The tartar of A blades is correct A tartars, and corresponding to the tartar of B blades, is then set to incorrect B tartars, or be rendered as one
Bar straight line, or be the tartar of entanglement, the B keys are set to correct A tartars and correct B tartars.
Above-mentioned technical proposal is taken, after AB power and energies, it is impossible to unlocked, also do not deposited with the method for A keys is filled up
Matched somebody with somebody the risk of B keys with A keys by people, solving the potential safety hazard of AB locks in the prior art, greatly improve AB locks
Security performance.
Structure novel and unique of the present invention, high safety has good social and economic benefit.

Embodiment
It is one embodiment of the present invention, including lock body 1, lock core 2, A blades 3 and B blades shown in Fig. 1-4, Figure 11-12
4th, lock pin 5, A keys 6 and B keys 7, the lock core is provided with blade groove, each blade groove vertically is put into three blades, two
A blades 3 and a piece of B blades 4 for being unworthy of spring equipped with spring, the A blades 3 and B blades 4 are provided with unlocking groove, in lock
Core 2 is longitudinally provided with lock pin groove perpendicular to blade groove, and built-in lock pin 5 is provided with locator card 21, the lock pin in the front end of lock pin groove
5 front end is provided with location hook 51, and lock pin 5 is provided with avoiding hollow groove 52, before AB power and energies, and avoiding hollow groove 52 aligns B blades 4, B leaves
Piece 4 is in avoiding hollow groove 52, after AB power and energies, and avoiding hollow groove 52 is no longer aligned with B blades 4, and lock pin 5 is made up of magnetically attractive material,
The lock body 1, which corresponds at lock pin 5, is provided with lock slots, lock slots is provided with unlocking pellet and its spring, in the corresponding positions of lock body 1
Install and be equipped with the magnetic patch 11 that pulling lock pin 5 carries out AB power and energies, the A keys 6, the A tartars corresponding to A blades 3 are outer milling
Tooth, correct tartar is set to incorrect B tartars corresponding to the curve molar of B blades 4, and in straight line, the B keys 7 are set
It is set to correct outer milling tooth A tartars and correct curved groove B tartars.
Before AB power and energies, unlocked using A keys 6, when insertion A keys 6, the unlocking groove of all A blades 3 aligns,
Straight line is formed, the B tartars of A keys 6 are not right, and the unlocking groove of B blades 4 does not align, but due to the avoiding hollow groove 52 of lock pin 5
B blades 4 are aligned, so the unlocking groove of B blades 4 does not align and has no effect on falling for lock pin 5 yet, now, in unlocking pellet
And its in the presence of spring, the inner of lock pin 5 is fallen into the unlocking groove of A blades, the outer rim of B blades 4 enters the empty avoiding of lock pin 5
In groove 52, the outer end of lock pin 5 and the outer round surface of lock core 2 maintain an equal level, the rotatable lock core 2 of twisting A keys 6, when turning to magnetic patch 11
During place, magnetic patch produces suction to lock pin 5, but the avoiding hollow groove 52 of lock pin 5 is stuck in above B blades 4, prevents lock pin 5 from moving axially,
So when being unlocked using A keys 6, AB power and energies, which do not continue twisting A keys 6, at this moment, to unlock.
The conversion of AB functions, insertion B keys 7, because B keys 7 have correct A tartars and B tartars, so now all
The unlocking groove part alignment of A blades 3 and B blades 4, forms straight line, in the presence of unlocking pellet and its spring, lock pin 5
In the unlocking groove for falling into A blades 3 and B blades 4, the rotatable lock core 2 of twisting B keys 7, when turning at magnetic patch 11, magnetic patch
Suction is produced to lock pin 5, the unlocking groove of B blades 4 now has alignd, lock pin 5 hindered without any, in magnetic patch
In the presence of 11, lock pin 5 is moved axially, and the location hook 51 of the front end of lock pin 5 reaches precalculated position, at this moment continues to twist B keys 7
It can unlock, end lock and extract B keys 7, during B keys 7 are pulled out, in the presence of the A tartars and B tartars of B keys 7, A
The unlocking groove of blade 3 and B blades 4 forces lock pin 5 move outward, and the outer end of lock pin 5 enters the lock slots of lock body 1, is formed
Lock-out state, now, the avoiding hollow groove 52 of lock pin 5 are also no longer aligned with B blades 4, and lock pin 5 has been contacted with B blades 4,4 pairs of B blades
The switching function of lock pin 5 has been turned on, and the location hook 51 of lock pin 5 has caught on locator card 21, and AB functions have been converted, this
When, if insertion A keys 6, because B blades 4 have been turned on to the switching function of lock pin 5, A keys 6 are opened to be opened not B leaf naturals
Not lock.
