Step S6, control chip 24 detect lock hook position it is in an open position when, to computer key send latch hook be in The information of open mode.
The course of work of anti-error lock in the embodiment of the present invention is as follows:
First, lockset unlocking process:
As shown in fig. 6, when computer key 20 inserts lock body 1, the trip lever 19a of computer key 20 inserts the solution of lock body 1 In lockhole 19, in the positioning hole 7 of the alignment pin 19b insertion lock bodies 1 of computer key 20, the insertion lock body of probe 18 of computer key 20 In 1 groove 16, the induction coil 17 on computer key induction coil 26 and anti-error lock on the probe 18 of computer key 20 Electromagnetic induction is carried out, by electromagnetic induction, anti-error lock is obtained after electric energy, the digital identity coding of oneself is first issued computer key Spoon 20, control chip 24 can receive the unlocking command of computer key 20, then control latch actuation control circuit 22 to promote spiral shell The adhesive of spool 5, the iron core 5a actions of solenoid 5, at this moment control pin 8 is downwards in free travel state, computer key trip lever 19a rotates, and drives lockset rotating dog 10 to rotate, rotating dog 10 promotes lockweight 13 to move right during rotation, simultaneously Control pin 8 is pressed down against, lockweight 13 is moved right to after certain position, latch hook 2 is unlocked, in the presence of latch hook spring 15 Ejection, lockset is unlocked, and can now extract computer key.
2nd, lockset process is locked:
Latch hook 2 is directed at the relevant position on lock body 1, latch hook 2 is down pressed, now lockweight 13 is in the first elastomeric element It is moved to the left in the presence of 4, when the top of latch hook 2 is across the first convex portion 13a of lockweight 13, during into its recess, lockweight 13 Turn right motion, the locking of latch hook 2 is lived, while work of the control pin 8 in the second elastomeric element 12 in the presence of the first elastomeric element 4 With lower upward motion, prevent lockweight 13 to left movement, so that lockset is in blocking.
3rd, control chip 24 obtains the process of the state of latch hook 2:
When lockset is in blocking, the magnet steel 14 on Hall component 3 and latch hook 1 on lock body 1 is corresponding, works as lock When tool is in open mode, the position mutual dislocation of magnet steel 14 on Hall component 3 and latch hook 2 on lock body 1, the inspection of latch hook position Slowdown monitoring circuit 25 is according to the state change of Hall component 3, it can be determined that go out whether lockset is in open mode or blocking, Control chip 24 can be sent to computer key 20 by signal accordingly.
To sum up, the anti-error lock of the embodiment of the present invention, due to the electricity for limiting or unclamping lockweight or latch Dynamic locking mechanism and the built-in circuit for controlling electric locking mechanism to act, the unblock of anti-error lock must be first by built-in circuit Electric locking mechanism inside unblock, external key can just unlock lockset, therefore improve the security of lockset, it is ensured that set The reliability of standby locking;Also, anti-error lock can gather the unlocking condition of itself, and the state of itself is passed to computer key Spoon, can improve the overall performance of anti-error security system.
Embodiment described above only expresses the several embodiments of the present invention, and it describes more specific and detailed, but simultaneously Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention Protect scope.
