The specific embodiment
Extremely shown in Figure 9 as Fig. 1, the magnetic that prevents the maloperation lockset key that unblocks, comprise housing, key body 2 and key bit 3, one side of housing is provided with battery 1, described key bit 3 constitutes double-decker by internal layer axis of rotation 4 and outer key headgear 5, constitutes non-contact magnetic force by magnet between described key body 2 and the key bit 3 and is in transmission connection.This is implemented described magnet and comprises the magnetic bullet that is located between key bit axis of rotation 4 and the key headgear 5, and is located at the magnetic post in the described key body 2; Described axis of rotation 4 is respectively equipped with the pellet shot from a slingshot hole with the corresponding site of key headgear 5, and described magnetic bullet is located in the pellet shot from a slingshot hole; The length of described magnetic bullet is greater than the pellet shot from a slingshot hole degree of depth of axis of rotation 4, and the length of magnetic bullet is less than the pellet shot from a slingshot hole degree of depth of key headgear 5.The described key headgear 5 of present embodiment is made as circulus, is installed on the outside of described axis of rotation 4, and the end of key headgear 5 is provided with locating groove 51.
In present embodiment when work,, described key body 2 is by changing the polarity of its magnetic post towards key bit 3 one ends, order about in the key bit 3 magnetic bullets towards or move back and forth away from key body 2.During lock operation, the magnetic post in the described key body 2 is identical with the polarity of magnetic bullet in the described key bit 3, and magnetic bullet is advanced in the pellet shot from a slingshot hole of described axis of rotation 4 by magnetic force, thereby key headgear 5 is connected together by magnetic bullet and axis of rotation 4.Because pellet shot from a slingshot length is greater than the pellet shot from a slingshot of the axis of rotation 4 hole degree of depth, when key inserts lock body,, and blocked by the lateral pin in the lockhole because of key headgear 5 and axis of rotation 4 are stuck by magnetic bullet, it can't be turned unblank.
During unlock operation, the magnetic bullet in the described key bit 3 is opposite with the polarity of described key body 2 inside magnet columns, and magnetic bullet is drawn in the pellet shot from a slingshot hole of described key headgear 5 by magnetic force, is connected thereby key headgear 5 is removed with axis of rotation 4.Because the pellet shot from a slingshot of the key headgear 5 hole degree of depth is greater than the length of magnetic bullet, when key inserts lock body, key headgear 5 is not blocked by magnetic bullet with axis of rotation 4, axis of rotation 4 is not blocked by lateral pin in the lockhole when turning key, the locating groove 51 of key headgear 5 heads blocks the pin of unblanking of lockhole, thereby unblanks.
Key of the present invention also has the function that is connected locking in the back of unblanking with lock body: the end of described key bit axis of rotation 4 is provided with groove 41, this groove 41 is consistent with locating groove 51 opening directions on the key headgear 5, can be so that link together with lock body behind the key unlocking.Key does not receive the locking authorization command after unblanking, can't arbitrarily extract key from lock body.When key bit axis of rotation 4 receives authorization command with key headgear 5, the groove 41 of key bit axis of rotation 4 is consistent with draw-in groove 51 opening directions of key headgear 5, when unblanking, key bit axis of rotation 4 rotates, the axis of rotation of lock core is rotation synchronously with it, allow lock pin be transferred in the locating groove 51 of key headgear 5, thereby can make key when locking, leave lock body.
Magnetic post in the key headgear of the present invention comprises calutron, and this device comprises microprocessor, circuit board, magnet and electromagnet, and described microprocessor control circuit plate drive magnet keeps electromagnet.As shown in figure 10, described housing is provided with display screen 6, control button 7 and loudspeaker, and described key bit also is provided with infrared electric supply installation 8.Do not have between key bit 3 of the present invention and the key body 2 and directly be in transmission connection, make rainwater etc. to infilter key body inside, thereby improve adaptive capacity to environment and reliability by key bit.
