Abstract

The present invention relates to a cipher code lock. It includes a turning component, and said turning component is formed from cipher code disk, code-regulating turning disk and fastener. Said lock changes the existent code-regulating principle, and can greatly simplify structure, and can utilize one-digit number and several-digit number to form arbitrary group number of cipher code.

Description

But a kind of coded lock of arbitrarily increasing and decreasing numeric code

Technical field:

The present invention relates to a kind of coded lock, but specifically be a kind of arbitrarily increasing and decreasing numeric code and only need the coded lock of an accent the combination disk of password.

The general combination disk of the coded lock of traditional structure can only be responsible for the password of three numbers, and the password number is few, is just decoded easily, and owing to listens the sound can find out password.Though the CN1274039A patent of invention has been carried out effective improvement to original coded lock, but this technology only is passively to the weak point because of tin sound can be decoded and violence is pulled out, primary structure has still passed on conventional art, increases recessed being pickled with grains or in wine on the rotary disk in addition, thereby has increased processing cost.This technology just improves to some extent, and does not have substance to jump.

Summary of the invention:

The purpose of this invention is to provide a kind of number of password big, do not have any prompting, the robber can't find and feel the coded lock of decoding and opening.

The present invention includes a rotary components, the rotary disk and the securing member that are contained in the rotating shaft that are connected the combination disk of rotating shaft outer end by rotating shaft are formed, be sleeved on the rotary disk in the rotating shaft, have only outmost one to be connected with rotating shaft, the inboard of a rotary disk of outermost is arranged the rotary disk that 3 above equal diameters are set at least.Except that rotary disk in the inside, all be provided with on all the other all rotary disks disc inwards and stir pin, the outside circle of all the other all rotary disks except that rotary disk of outermost and on all be provided with a random length arc stir cotter way, for stirring the pin motion, all be provided with a groove on all rotary disks, be provided with external screw thread and steel pin hole at the interior place of rotating shaft, be used for dress and lean on and be fastened on lock body, at the active property of lock body interior arrangement dynamic resistance sheet, this group moving plate contacts with the face of cylinder of all rotary disk, stops the rotary disk of contraposition to be rotated by the company of being with by this contact point or face friction.

Unique distinction of the present invention only is that a combination disk can command the rotary disk of any number, forms the password of any amount, and initiative is listed the revolution of combination disk in password, can form the password of one digit number and long number combination.The present invention is easy to make because structure is ingenious, and the robber can't find to feel to decode lock is opened, and not only increases the function of coded lock, and simplifies the structure, and reduces cost, and has good society and economic benefit.

Description of drawings:

Cross-sectional view when Fig. 1 is provided with 6 rotary disks for the embodiment of the invention;

Fig. 2 is the structural representation of rotary disk;

Fig. 3 is the back elevation of Fig. 2.

The specific embodiment:

Referring to Fig. 1, Fig. 2 and Fig. 3, the present invention includes a rotary components, this rotary components is made up of combination disk 1, rotating shaft 2, rotary disk 3, and rotating shaft 2 links to each other dead in line with the inboard of combination disk 1.Supportingly in rotating shaft 2 be provided with 6 and (any number can be set, the many more number of password of number are big more) rotary disk 3 of equal diameters, a wherein outmost rotary disk 3 is connected with rotating shaft 2, except that rotary disk in the inside, all be provided with on all the other all rotary disks disc inwards and stir pin 5, except that rotary disk of outermost, the arc that all is provided with random length on the outside disc of all the other all rotary disks is opened and is stirred the pin tip 6, stir cotter way 6 and adjacent rotated disk 3 to stir pin 5 corresponding, for stirring pin 5 motions.All have groove 4 on all rotary disks, groove 4 is the lock-bit groove.Groove 4 on all rotary disks point-blank time lock is opened.All be provided with partition 9 between adjacent two rotary disks 3 less than the interior camber line place diameter of a circle of stirring cotter way 6.Rotating shaft 2 inner segments are provided with external screw thread 7 and steel pin hole 8, are used to be abutted against with fastening.

The following examples are that example is described operating principle of the present invention when 6 rotary disks are set.

The 6th rotary disk is responsible for accessing the first digit in the password, in the time will transferring first digital, needing changes towards a direction rotational password dish number earlier, (6 rotary disks need change 5 at most to be changeed, the rest may be inferred) confirm to be rotated further accent to first number after the 6th rotary disk driven, first digit transfer to after, backward rotation combination disk again, transfer the 2nd numeral, it should be noted that, the length of stirring cotter way and the 4th on the 5th rotary disk, the 3rd, the length sum of stirring cotter way on the 2nd group's rotary disk equals the amount of spin of combination disk, when transferring the 2nd when digital, combination disk must oppositely turn over the above-mentioned cotter way length sum of stirring, stirring pin and could drive the 5th rotary disk rotation on this moment the 4th rotary disk is rotated further then, transfers the second number code position, remaining password figure accent, is no longer described with preceding identical here to mode.The present invention lists the revolution that combination disk is rotated in password figure, need remember the revolution (during convenient, revolution mark dish being set preferably) that combination disk is rotated when transferring sign indicating number.Lift a password example elaboration accent coding mode below, drafting unlocking cipher is 3,32,26,18,11,5, according to the method described above, first digit 3, as changeing back aligning 3 for clockwise rotating number, 32 of second digits aim at 2 again after rotating counterclockwise 3 commentaries on classics.The 3rd is 26, then changes the back to aim at 6, the four be 18 for clockwise rotating 2, and then to aim at 8, the five again after changeing be 11 in order to rotate counterclockwise 1, then changes the back to aim at 1, the six be 5 for clockwise rotating 1, promptly rotates counterclockwise aligning 5, locks and promptly opens.If 20 numerical digits are arranged on the combination disk, then this embodiment number of password is (20) ⁶=6,400 ten thousand, also do not comprise the revolution number.

The present invention is when being used for important place, and more than the rotary disk number can being increased to more than ten, its number of password can far surpass the TM card, and (number of password during as 12 rotary disks is (20) ¹²=4,086,000 hundred million, the TM card is 280,000,000,000,000).
