Abstract
The utility model relates to an anti-drilling automatic hole-closing safety lock. An automatic hole-closing anti-drilling type bulkhead device is arranged inside a key hole, and a lock shell is provided with a magnetic post pin. The displacing and arrangement of the N and the S poles of a magnetic column pin can combine a plurality of cipher symbols, so that the cipher repetition rate of each lock is reduced to lowest. In addition, the closing of the key hole realizes automation, and once the lock is broken by a drill, the bulkhead which is used for closing the key hole can rotate right and left inside the key hole. The anti-drilling automatic hole-closing safety lock has simple operation without memorizing the cipher codes, completely prevents the phenomenon of damaging by drill, and thus strengthens the insurance reliability of the lock.
Description
The utility model belongs to lock technology field, is specifically related to a kind of improvement to existing sealed key hole plug structure and anti-drilling technology.
Existing machinery formula sealed key hole safety lock, majority is the open and close by several groups of numeral check mark disc mechanism control sealed key hole plugs, the safety lock of this mechanism, analyze from result of use, have two aspect defectives at least: the plug of one sealed key hole is that the long rails in the keyhole seesaws, can not be in keyhole left-right rotation on the spot, after closing, extremely should be destroyed, make key to insert, cause a whole set of lockset to be scrapped by drilling tool.It two must keep password firmly in mind, and during unlatching, numeral more than twice, is upset password to the positive and negative at least rotation of dialer again after closing, thereby the loaded down with trivial details very inconvenience of the program of unblanking.
The purpose of this utility model is to provide a kind of anti-drilling automatic sealing of hole safety lock, after this locked plug that closes keyhole is closed, can be along with the destruction of drilling tool left-right rotation on the spot in keyhole, be intended to stop the phenomenon generation that drilling tool destroys, sealed key hole has been realized automation, and has simplified the program of unblanking.
For achieving the above object, the technical solution of the utility model is: on keyhole Inner Front End inwall disc, have horizontal groove of a week, the anti-drilling cylinder shape of automatic sealing of hole plug device is set in the keyhole, after this device is closed, magnetic conduction ball part in it is stuck in the interior horizontal groove of keyhole, destruction along with drilling tool, roll in the horizontal groove of magnetic conduction ball in keyhole in the anti-drilling cylinder shape plug, make the plug of sealed key hole can be in keyhole left-right rotation on the spot, a magnetic pin all is set in several through holes of opening on the lock housing, a thrust spring is all settled on each magnetic pin top, each magnetic pin can slide at the through hole cathetus, anti-drilling shell at lock housing front end face suit, the key main body is cylinder, magnetic pin quantity in magnetic pin on the key and the lock housing equates, polarity is identical, the position is corresponding one by one, disk magnetic polarity in the disk magnetic polarity of key cylinder body front end and the anti-drilling cylinder shape plug is opposite, the position correspondence, lock housing magnetic pin interior and on the key passes through N, the permutations of the S utmost point and the conversion of position, can be combined into very many cipher symbols, this technical scheme can prevent effectively that drilling tool from destroying, when opening the plug of sealed key hole, needn't memory cipher.
Below in conjunction with accompanying drawing the technical solution of the utility model is further described:
