The state of survey designs the angle of rotation, and cam 4 is contacted with another detection probe, control panel 6 records information and is simultaneously transmitted to key, key
Spoon issues lock and has turned on sound, and unlocking terminates.It extracts key to stop powering to fine motion motor, fine motion motor stop motion resets
Part 11 drives castle wheel 7 to rotate by a certain angle counterclockwise and reaches the other end of arc groove 71, and castle wheel 7 stops operating, castle wheel 7
On first sliding groove 81 be aligned with steel ball 84, steel ball 84 is fallen into the first sliding groove 81 of castle wheel 7, and lock gall 3 and cam 4, which disconnect, to be connected
It connects, realizes the whole idle running of lock gall 3.
Process is shut, key is aligned to insertion tapered end 2 with keyhole 23, key is supplied by probe and tapered end 2 to control panel 6
Electricity, single-chip microcontroller identifies that control panel 6 encodes by Electronic Coding mode on the key, controls fine motion motor by control panel 6 after decryption
Rotation, and castle wheel 7 is driven to rotate clockwise, two steel balls 84 are pushed outwardly by castle wheel 7, and steel ball 84 is along second sliding slot 82
Into in third sliding slot 83, castle wheel 7 continues to rotate the end limit for moving to arc groove 71 on castle wheel 7, at this time castle wheel 7
84 direction of motion of steel ball is choked, steel ball 84 links cam 4 and 3 integral part of lock gall, and key is given notice, and rotates key counterclockwise
Spoon drives 3 part of lock gall and 4 unitary rotation of cam, and cam 4 is during axial-rotation because of the U-shaped thread groove 91 in its surface and ball
First gear pin 92 contacts, and moves after pushing 4 transverse direction of cam by bulb shelves pin 92, cam 4 and wherein one inspection when rotating first angle
Probing needle successively separates, and control panel 6 records information and is transmitted to key；Cam 4 and another detection probe when rotating second angle
Separation, control panel 6 record information and are transmitted to key, and key issues lock and is turned off sound, shuts end.Extract key fine motion motor
Stop motion, castle wheel 7 reset, and lock gall 3 dallies, and detailed process is identical as unlocking, and this will not be repeated here.With inspection in the present embodiment
Probing needle is illustrated for being arranged 2, and certainly, detection probe can also be arranged more according to actual needs, and every detection is visited
Needle is used to detect the information of corresponding different location state when unlocking or shutting, herein with no restrictions, first jiao in the present embodiment
Degree is 45 degree, and second angle is 810 degree.
It contacts or separates in case of a portion detection probe during above-mentioned unlocking, that is, failure of unlocking, key
User can be reminded；It separates in case of only some detection probe during shutting or contacts failure of unlocking, key also can
Remind user；Greatly reinforce the safety of lock in this way, at the same user can be checked by key open and close lock record and open at present,
Shut state.
