23, the magnetic coil 17 in lock core 3 generates magnetic force after being powered and the elastic force of spring 15 is overcome to be attracted iron core baffle 16, locking plate 12
It is moved to the left, lock hole 19 is moved to the middle position of keyhole, can be by electron key B by pulling out in the lock hole 19 of locking plate 12
Out, after electron key B is mobile, the not closed electronic circuit inside lock core 3 cannot be formed by the conductive shackle in electron key B
One complete path, conductive shackle 24 power off at once with Electrical key, the lockhole position in lock 2 stuck at once of locking post 10, i.e.,
Achievable locking.Since two reset springs 11 being equipped between heel piece 9 and mounting base 7 are in the state that door lock A locks
It is all normal compressive state, so will not cause to damage to the elastic force of reset spring 11, whole device can long-term normal use.
The identification code of all electron key B and door lock A can be changed by the upper computer software on computer, or be interpreted as point
With permission, just because of having the functional design of above-mentioned institute and support, it is possible to realize all keys according to different identification
Identical lock is opened or cannot be opened to code and the different rights being assigned to, that is to say, that the difference of role determines identification code
Difference, the difference of identification code finally determine the difference of unlocking authority.And lock avoid in production waste can be designed as it is same
Kind structure, the difference for the identification code that difference is only deposited in advance, such design can simplify production technology, efficiently, pacify
It is complete and practical.
To sum up, the present invention is not limited to above-mentioned specific embodiments.Those skilled in the art are not departing from spirit of the invention
Under the premise of range, several change and modification can be done.Protection scope of the present invention should be subject to claim of the invention.
