Problems solved by technology

[0002] At present, almost all mechanical digital locks use integral disc-type digital disks that cannot automatically change codes, and use round pins as dial pins and password positioning pins, and even some digital disks use stamping bosses instead of password round nails Positioning, some digital discs that can change codes also have a large blind area that cannot be changed, and inaccurate positioning sometimes leads to garbled characters. Disadvantages: First, it is very difficult to set a password, especially the passwords set by traditional combination locks are almost random, and cannot be accurately set at one time according to people's wishes; second, the amount of encryption is low, and it is easy to steal password bits; The most fatal flaw is that they must adjust the lock card slot to a straight line corresponding to the lock card plate to open the lock, resulting in the current situation of thieves punching a hole to open a hundred locks, which has little security significance

Abstract

The invention relates to digital disks of mechanical digital locks, in particular to an adjustable positioning disk of a digital disk of a mechanical digital lock. The adjustable positioning disk comprises an annular inner disk with a circle center hole and an outer disk; the outer disk and the inner disk are coaxially connected and positioned by a positioning piece; the excircle of the outer disk is provided with a lock card slot; the circle center hole of the inner disk is provided with a positioning guide sliding chute; and inner wall surfaces on two sides of the positioning guide sliding chute are parallel with each other along the radius direction. The adjustable positioning disk has simple structure, can freely adjust the inclined angle between the lock card slot and the positioningguide sliding chute and is convenient to install and debug. When the adjustable positioning disk is applied to a digital disk combination, inclined angles between the center line of the lock card slot of each positioning disk of the digital disk and the center line of the positioning guide sliding chute on the 360-degree circumference are different or not completely same, thereby not only realizing automatic code variation of the digital lock, but also forming a password mode of a curved lock card slot. The invention is particularly suitable to be matched with metal digital locks of various safes, vault doors and burglar-proof vault door.
