Lock core in one embodiment of the present utility model, the lock core being used in combination for above-mentioned computer key, lock core
Including lock housing 400, lock gall 500 and magnetic bullet 600.Magnetic bullet 600 is in blocking, can limit lock gall 500
Rotate, make lock core locking；When magnetic bullet 600 is in released state, the rotation limitation to lock gall 500 can be released, makes lock core
Unblock.Magnetic bullet 600 is preferably soft magnetism pellet.During computer key insertion lock core unblock, magnetic part 240 and magnetic bullet
600 are coaxially disposed.
Specifically, as shown in figure 5, lock gall 500 includes relative the first lock gall 510 and the second lock gall 520 connect, described first
Lock gall 510 is fixed lock gall, is fixedly connected by pin 410 with lock housing 400, and the second lock gall 520 is movable lock gall, for turning
Dynamic unblock.During locking, the first end of magnetic bullet 600 is embedded in the first lock gall 510, and the second end is embedded in the second lock gall 520
Interior, magnetic bullet 600 is in blocking, and now the second lock gall 520 can not rotate, therefore lockset can not unlock.When computer key
During spoon insertion lock core, the magnetic part 240 in computer key enables the first end of magnetic bullet 600 to be retracted from the first lock gall 510
To the second lock gall 520, rotary spacing of the magnetic bullet 600 to the second lock gall 520 is released, now the second lock gall 520 can rotate,
Therefore lockset can unlock.
Further, magnetic bullet 600 is also arranged with spring, and compression spring is arranged on the accommodating hole on the second lock gall 520
It is interior.Magnetic bullet 600 from the first lock gall 510 be retracted to the unblock of the second lock gall 520 when, spring-compressed, when computer key revolution is multiple
Extracted behind position, magnetic bullet 600 resets under the action of the spring, lockset locking again.
In one embodiment, above-mentioned lock gall is additionally provided with mechanical billiard 700, is acted by mechanical billiard 700, to lock
The rotary spacing of courage 500, now lock core is mechanical lock.Mechanical billiard 700 is in blocking, can limit turning for lock gall 500
It is dynamic, make mechanical lock locking；When mechanical billiard 700 is in released state, the rotation limitation to lock gall 500 can be released, makes machine
Tool lock core unlocks.During unblock, mechanical billiard 700 is engaged with the solution lock crossbeam 221 in the unlocking head 220 of computer key, unblock
Groove 221 releases rotary spacing of the mechanical billiard 700 to lock gall, and mechanical billiard 700 is in released state.On mechanical billiard 700
Spring is again provided with, is extracted after computer key revolution resets, mechanical billiard 700 and magnetic bullet 600 are respectively in spring
Effect is lower to be resetted, and makes lockset locking again.
In another embodiment, above-mentioned lock core is additionally provided with electrical equipment blocking mechanism 800, and now lock core is intelligence
Can lock core.The probe assembly of computer key can power to the electrical equipment blocking mechanism in lock core, so that intelligent lock core unlocks.
Electrical equipment blocking mechanism 800 specifically includes the second solenoid 810 and the second dynamic iron core 820 being arranged in the second solenoid.
Lockset in one embodiment of the present utility model, including lock core, lock core are the lock core in any of the above-described embodiment.
The lockset is adapted with the computer key in the utility model, it is possible to increase the anti-theft of lockset.
Computer key operation principle of the present utility model is as follows：
When inserting lock core, it is mechanical lock or intelligent lock core that computer key detects the lockset by internal circuit.Such as
Fruit is mechanical lock, then reads code value, then judges whether code value is correct, and then judge whether to unlock.If intelligent lock core,
Probe 251 is then powered and communicated for intelligent lock core, and obtains intelligent lock core code value, judges whether code value is correct, and then judgement is
No unlocking.
(1) mechanical lock operation principle is unlocked：
As shown in Figure 5,6, when mechanical lock is in blocking, magnetic bullet 600 and the part of mechanical billiard 700
In the first lock gall 510, a part is in the second lock gall 520, and the second lock gall 520 can not rotate, therefore lockset can not unlock.
When above-mentioned computer key inserts mechanical lock, solution lock crossbeam 221 coordinates with mechanical billiard 700, releases mechanical elastic
The rotation limitation of 700 pair of second lock gall 520 of son, computer key reads the coding information of lock core chip, if the coding information of chip
Correctly, the first dynamic iron core 232 in unlocking head 220 drives magnetic part 240 to be moved to unlocked position, because magnetic part 240 with
Magnetic bullet 60013 is coaxial, so under magneticaction, the compression spring of magnetic bullet 600, departs from the first lock gall 510, releasing pair
The limitation of second lock gall 520, computer key can drive the second lock gall 520 to rotate, realize unlocking function.When computer key turns round
Extracted after reset, magnetic bullet 600 and mechanical billiard 700 reset under the action of the spring, lockset locking again.
(2) intelligent lock core operation principle is unlocked：
As shown in fig. 7, when intelligent lock core is in blocking, the inwall of lock core shell 210 is stretched into one end of lockweight 830
On groove in, the first dynamic iron core 232 of the first solenoid 231 withstands on the other end of lockweight 830, prevents lockweight 830
Mobile, lock core can not rotate, therefore lockset can not unlock.
When above-mentioned computer key inserts intelligent lock core, such as Fig. 8, the electricity of probe 251 and intelligent lock core in computer key
Pole 900 contacts, and computer key reads lock core code value, if code value is correct, computer key is electric to smart lock in-core by probe 251
The second solenoid 810 in member locks mechanism is powered, and the second dynamic iron core 820 in the second solenoid 810 of intelligent lock core is logical
Electric after-contraction, the stop to lockweight 830 is released, when above-mentioned computer key rotates, lockweight 830 is in lock core shell 210
Shunk under the compressing of wall, the compression spring of lockweight 830, until lock core turns to the unlocked position of lockset, computer key revolution is multiple
Extracted behind position, lockweight 830 resets under the action of the spring, lockset locking again.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model patent scope.It should be pointed out that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
