A kind of high security anti-error lock, include padlock and unlock key, described padlock comprises lock body, latch hook, deadlock lever, trip lever, pellet, identity code, described latch hook is installed on above lock body, deadlock lever and trip lever be vertical arrangement be arranged in lock body, its structural feature is: described trip lever is inverted T shape structure, the straight portion of inverted T shape is cylindrical-shaped structure, a part for upper end, straight portion upwards extends to form the end face structure of scalariform, the straight portion of inverted T shape is also provided with a cannelure, the centre of the bottom of the transverse part of inverted T shape is provided with square blind hole, the step surface in inverted T shape transverse part and straight portion is provided with multiple blind holes, trip lever is installed in lock body in straight portion mode upward, lock body place corresponding to the blind hole on the step surface of inverted T shape trip lever is also provided with corresponding blind hole, blind hole place on trip lever step surface is provided with the pellet that can attract magnet, pellet is fixed in the blind hole of the step surface of trip lever by Compress Spring, spring is positioned at the below of pellet, when padlock is in locking state, pellet extend in the corresponding blind hole of lock body, the straight portion of trip lever is provided with the annular groove of a circle, be provided with at the lock body place that trip lever straight portion annular groove is corresponding and be in conplane through hole with annular groove, the alignment pin for locating is provided with in through hole, the lock body of the periphery, bottom of the transverse part of trip lever inverted T shape is provided with identification code module,
Described unlock key includes housing, the upper end of housing be provided with padlock trip lever transverse part bottom on the square spigot that matches of square blind hole, on the top of housing cavity, square spigot place is provided with reading terminal, control panel is provided with in housing, control panel is connected with reading terminal and motor respectively, motor shaft is by nut-screw rod anatomical connectivity one support, support is provided with several magnetic elements, blind hole quantity on trip lever step surface on the distribution of magnetic element and padlock is suitable, magnetic element when being in the normal state away from housing cavity top.
The padlock of this structure, owing to being provided with blind hole on the step surface of trip lever, and be provided with blind hole at the corresponding site of lock body, pellet is provided with at the blind hole place of the step surface of trip lever, pellet is fixed in the blind hole of step surface by Compress Spring, when padlock is in locking state, pellet extend in the blind hole of lock body, like this when needs unlock, the square spigot of unlock key is inserted in the square blind hole of trip lever transverse part, reading terminal on unlock key head reads the identity code on lockset, after unlock key recognition and verification, the support that motor pushing in unlock key is provided with magnetic element is moved upward to unlock key top, pellet moves down and all sinks in the blind hole of trip lever under the magneticaction of magnetic element, now, rotate unlock key, trip lever rotates under the square spigot of unlock key drives, driving deadlock lever moves, thus the stop of release to latch hook, latch hook outwards flicks under the force of a spring, thus complete the unlocking operation of lockset.
Nut in unlock key is arranged on motor shaft, and screw mandrel is connected with support.
In sum, the present invention's following advantage compared to existing technology:
Compared with the lockset that existing power industry is conventional, the theftproof performance of lockset of the present invention significantly improves, avoid artificially arbitrarily unblanking and the potential safety hazard that produces, outside unauthorized unlock key, other instruments are difficult to carry out unlocking operation to lockset, and meanwhile, this invention lockset lock core does not have long and narrow unlock hole, ensure that the insertion that key is good, ensure the reliability of locking operation; This invention improves the protective capacities to equipment and personal safety, has ensured the safe operation of equipment, has had very high practicality and economic benefit.
