When step S6, control chip 24 detect that lock hook position is in an open position, send the information that latch hook is in open mode to computer key.
The course of work of the anti-error lock in the embodiment of the present invention is as follows:
One, lockset is unblanked process:
As shown in Figure 8, when computer key 20 inserts lock body 1, the trip lever 19a of computer key 20 inserts in the unlock hole 19 of lock body 1, the alignment pin 19b of computer key 20 inserts in the locating hole 7 of lock body 1, the probe 18 of computer key 20 inserts in the groove 16 of lock body 1, electrical contact on the probe 18 of computer key 20 and the electrical contact 17a on anti-error lock, 17b, 17c contacts (as shown in Figure 8), computer key 20 begins through these electrical contacts and powers to anti-error lock, after anti-error lock obtains electric energy, first the digital identity of oneself coding is issued computer key 20, control chip 24 can receive the unlock command of computer key 20, then control latch actuation control circuit 22 and promote solenoid 5 adhesive, the iron core 5a action of solenoid 5, at this moment control pin 8 and be in free travel state downwards, computer key trip lever 19a rotates, lockset rotating dog 10 is driven to rotate, rotating dog 10 promotes lockweight 13 and moves right in the process rotated, control pin 8 is extruded downwards simultaneously, after lockweight 13 moves right to certain position, latch hook 2 unlocks, eject under the effect of latch hook spring 15, lockset is unblanked, now computer key can be extracted.
Two, lockset process is locked:
Latch hook 2 is aimed at the relevant position on lock body 1, down press latch hook 2, now lockweight 13 is moved to the left under the effect of the first elastomeric element 4, when latch hook 2 top strides across the first protuberance 13a of lockweight 13, when entering its recess, lockweight 13 is turned right motion under the effect of the first elastomeric element 4, latch hook 2 locking is lived, control pin 8 to move upward under the effect of the second elastomeric element 12 simultaneously, make lockweight 13 to left movement, thus not make lockset be in blocking.
Three, control chip 24 obtains the process of latch hook 2 state:
When lockset is in blocking, Hall components and parts 3 on lock body 1 and the magnet steel 14 on latch hook 1 corresponding, when lockset is in open mode, Hall components and parts 3 on lock body 1 and the magnet steel 14 position mutual dislocation on latch hook 2, latch hook position detecting circuit 25 changes according to the state of Hall components and parts 3, can judge whether lockset is in open mode or blocking, control chip 24 can send to computer key 20 by signal accordingly.
To sum up, the anti-error lock of the embodiment of the present invention, owing to having for limiting or unclamping the electric locking mechanism of lockweight or latch and the built-in circuit for controlling electric locking mechanism action, the unblock of anti-error lock must by the electric locking mechanism of the first unlocking both interior of built-in circuit, external key just can unlock lockset, therefore improve the safety of lockset, ensure that the reliability of device latchup; Further, anti-error lock can gather the unlocking condition of self, and the state transfer of self to computer key, can improve the overall performance of anti-error security system.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
