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

Embodiment 1

[0029] Such as figure 1 , 2 Shown is a positioning disc of a fixed mechanical digital lock dial, the positioning disc is an annular disc 2 with a center hole 7, the outer circle of the annular disc has a locking groove 1, and the inner circumference of the center hole is provided with a A positioning guide chute 5, the positioning guide chute 5 is parallel to the inner wall surface in the radial direction, and the angle between the positioning guide chute and the locking slot is 90 degrees. The angle between the positioning guide chute and the locking slot can be any angle from 0 to 360 degrees, for example Figure 9-16 shown.

Embodiment 2

[0031] Such as image 3 , 4 Shown is a positioning plate of a fixed mechanical digital lock dial, the positioning plate is an annular plate 2 with a center hole 7, and the outer circle of the annular plate has a locking groove 1, and the inner circumference of the center hole is provided with A positioning guide chute 5 is provided. The positioning guide chute has a guide rail 4 along the inner wall surface in the radial direction. The guide rails are parallel. The angle between the positioning guide chute and the locking slot is 90 degrees. The angle between the slot and the lock slot can be any angle from 0 to 360 degrees.

Embodiment 3

[0033] Such as Figure 5 , 6 Shown is a positioning plate of a fixed mechanical digital lock dial, the positioning plate is an annular plate 2 with a center hole 7, and the outer circle of the annular plate has a locking groove 1, and the inner circumference of the center hole is provided with A positioning guide chute 5 is provided, the positioning guide chute 5 is parallel to the inner wall surface in the radial direction, a shoulder 3 is provided on the inner circumference of the center hole on one end surface of the annular disk, and an "O" shaped retaining ring groove is provided on the inner wall of the center hole 6. The angle between the positioning guide chute and the lock slot is 90 degrees, and the angle between the positioning guide chute and the lock slot can be any angle from 0 to 360 degrees.

Abstract

The invention relates to a digital disc of a mechanical type digital lock, in particular to a positioning disc of a digital disc of a fixed and mechanical type digital lock. The positioning disc is an annular disc provided with a circle center hole; the outer circumference of the circle center hole is provided with a locking card slot, and the inner circumference is provided with a positioning guide sliding slot; and the inner wall surfaces of both sides of the positioning guide sliding slot along a radius direction are parallel. The positioning disc has simple structure; included angles on the circumference of 360 degrees between center lines of the locking card slot and the positioning guide sliding slot of the positioning disc of each digital disc are different from one another or not identical when the positioning disc is applied to a digital disc assembly; and the positioning disc can realize the automatic code variation of the digital lock and also form a curve locking card slot code mode through the different variation of the included angles between the center lines of the locking card slot and the positioning guide sliding slot of the positioning disc. The invention is especially suitable for being matched with the mechanical type digital locks of various safety boxes, vault doors and theftproof storeroom doors.
