Description

The digital disk mechanism of mechanical type digital lock

One, technical field:

The utility model relates to a kind of mechanical type digital lock, particularly its digital disk.

Two, background technology:

At present, domestic and international nearly all mechanical type digital lock, particularly all kinds of safety cabinets, the national treasury door, the supporting combination disk of the mechanical type digital lock of antitheft storehouse door almost is three combination disk devices, and all adopt the round pin nail as the shifting block pin, it is the password alignment pin, even some digital disk adopts the simple structure of punching press boss to replace code pins to establish close location, the major defect of its existence is: the one, the password difficulty is set, the conventional cipher lock is provided with password and almost all bumps out carelessly, therefore can not once accurately establish sign indicating number according to people's wish, all can't reset to reset password by wish the time many; The 2nd, it is few to establish close amount, and there are linkage in open system and combination disk system, steals that to survey the password position easy; The 3rd, do not having can't to realize open operation or the like under the situation of light, not only the safety of corollary equipment is low, and uses inconvenience.

Three, summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of digital disk mechanism of mechanical type digital lock is provided, and it is huge to make combination padlock establish close amount, and can be provided with according to the personal inclination is accurately quick, and security performance is strong.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the digital disk mechanism of mechanical type digital lock, the outer circumference surface that has the digital disk of circle center hole is provided with a locking trough perpendicular to center of circle direction, digital disk is provided with radial type shifting block pin-and-hole and the screw hole that quantity equates, screw hole and radial type shifting block pin-and-hole are separately positioned on the circumference of different-diameter and the position of intersecting point of the reticule that 360 degree are divided equally, and the radius of a circle at place, radial type shifting block pin-and-hole position is less than the radius of a circle at place, screw hole position; Plug-in mounting radial type shifting block pin in a radial type shifting block of the digital disk pin-and-hole, the digital disk another side screw hole fixed shifting block pin that is threaded, radial type shifting block pin is support end has hinged round pin along the shifting block center line a trapezoidal shifting block, the base angle of shifting block pin both sides is the location fulcrum, the location fulcrum contacts with locating shoulder is movable, and locating shoulder is arranged on the circle center hole circumference of digital disk one or both sides.

A/F on the described locking trough outer circumference surface is less than the width of digital disk inside opening.

The hinged round pin of described radial type shifting block pin and radial type shifting block pin-and-hole rotate pegs graft, and the location fulcrum of hinged round pin both sides contacts with the locating shoulder outer circumference surface is movable.

Described fixed shifting block pin is the screwed round pin nail of an end.

The digital disk mechanism of the utility model mechanical type digital lock compared with similar products, has significant effect: adopt radial type shifting block pin, the diameter of fixing shifting block pin of can staggering because of the angle of oscillation of radial type shifting block pin is poor, eliminate the shifting block diameter stack scale error of each variation that produces when fixedly the shifting block pin is dialled mutually, it is accurately quick that combination padlock is established when close when opening, if close amount factor code-disc can become many times of increases and increase, can reach tens billion of more than one hundred billion groups easily and establish close amount, the more important thing is that it makes mechanical type digital lock accomplish zero location arbitrarily, tell others with password exactly, others also can't open this lock, it can also make mechanical type digital lock accomplish need not the light situation following moment open, so it makes mechanical type digital lock safer, use conveniently, open more quick.

Four, description of drawings:

Fig. 1 is the utility model digital disk structural representation.

Fig. 2 is the sectional view of Fig. 1.

Fig. 3 is the structural representation of radial type shifting block pin.

Among the figure: 1 digital disk, 2 fixing shifting block pins, 3 radial type shifting block pins, 4 location fulcrums, 5 locking troughs, 6 screw holes, 7 radial type shifting block pin-and-holes, 8 locating shoulders, 9 circle center holes, 10 hinged round pins.

Five, the specific embodiment:

The utility model will be further described below in conjunction with accompanying drawing.

The digital disk mechanism of mechanical type digital lock as shown in Figure 1, have on the outer circumference surface of digital disk 1 of circle center hole 9, with reticule wherein is that a degree of depth is set is 16 millimeters locking trough 5 to center line, the nearly center of circle end width of locking trough otch is wideer than excircle width, be provided with 12 reticules along 360 degree circumference, every reticule is 30 degree, every reticule is provided with 1 radial type shifting block pin-and-hole 7 and screw hole 6 on the digital disk, screw hole and radial type shifting block pin-and-hole are separately positioned on the circumference of different-diameter on the digital disk and the position of intersecting point of the reticule that 360 degree are divided equally, and the residing circumference radius of radial type shifting block pin-and-hole is less than the residing circumference radius of screw hole; Fixed shifting block pin and radial type shifting block pin are installed in the two sides of digital disk respectively, be positioned on the identical graduation line, plug-in mounting radial type shifting block pin 3 in the radial type shifting block pin-and-hole, the screw hole fixed shifting block pin 2 that is threaded, radial type shifting block pin 3 has the trapezoidal shifting block of hinged round pin along the shifting block center line for support end, the hinged round pin 10 of radial type shifting block pin rotates with radial type shifting block pin-and-hole and pegs graft, the base angle of shifting block pin both sides is location fulcrum 4, location fulcrum and locating shoulder 8 movable contacts, form positioning relation, locating shoulder is arranged on the circle center hole circumference of digital disk one or both sides, and the cross section is square.
