Disclosure of Invention

The utility model provides a formula mechanical coded lock is dialled more to fixed wheel stator, including lock body, lock core, cotter, runner, plectrum, its characterized in that: the plurality of shifting pieces are continuously attached to the whole inner circumference of the lock body and are arranged on the end surface of the lock core, each shifting piece is provided with a main shifting piece, a plurality of specific shifting pieces and a plurality of false shifting pieces, the widths of all the shifting pieces in the whole length are the same, and the main shifting piece and the specific shifting pieces are shifting pieces with set passwords; the rotating wheel is provided with a free wheel, a driving wheel and a plurality of driven wheels, the rotating wheel is annular as a whole, the inner peripheral end surface of the rotating wheel is provided with a \ Ui shape or \ Ui shape groove which corresponds to the pin bolt and can switch the coded lock, the free wheel is a rotating wheel which can not move after being positioned firstly, and a U-shaped groove can be arranged on the inner peripheral end face of the free wheel which does not play a role in locking; all the rotating wheels are arranged on the cylinder in the lock body; the main shifting piece is a password setting shifting piece and can be connected with all rotating wheels, only one convex shifting piece corresponding to the main shifting piece is arranged on the periphery of the driving wheel, the main shifting piece can axially move and is connected with the convex shifting piece on the periphery of the driving wheel at a fixed circumferential point position, the driving wheel always rotates along with the main shifting piece, and meanwhile, the free wheel and all the driven wheels are also respectively provided with one convex shifting piece which is rotatably connected with the main shifting piece. Convex dials which are in one-to-one correspondence with all the dialing pieces are respectively arranged on the outer end faces of all the driven wheels and the free wheels. The specific shifting pieces are also password setting shifting pieces, only the driven wheels which are respectively and correspondingly arranged are respectively connected, one corresponding driven wheel is added when one specific shifting piece is added, and all the specific shifting pieces can be respectively connected with the driven wheels which are correspondingly arranged at any position; all of the numerous false dials set by non-password can be connected with the free wheel which can not move after being positioned firstly (or can be connected with a part of the driven wheel completely or partially at the same time) to increase the probability of illegal operation errors to the utmost. The pin bolt is arranged in a cylinder in the lock body and is connected with the lock core and all the free wheels, the driving wheel and the driven wheel.

The convex position setting of plectrum group: the width of the part of the poking convex position arranged on the poking sheet is divided into one of a plurality of areas to set a position as the position of the poking convex arranged on all the poking sheets; meanwhile, convex dials corresponding to all the zone bit numbers of all the poking convex of all the poking sheets are arranged on the peripheries of the free wheel and all the driven wheels, and scales corresponding to all the zone bit numbers are marked on the code panel corresponding to each poking sheet. When the password point is involved in the calculation, the convex dialing number obtained by rotation is calculated as a base number. According to the principle, on all panels provided with codes corresponding to the dials, the password point number = N (the number of dials 3 provided) × (each dial) zone number = free wheel convex dial number = each driven wheel convex dial number, for example, if the width of the dial is 2.5mm, only a single dial (the thickness is generally 0.3-0.5 mm) can be provided, and if the width is 4mm, two dial projections can be provided, namely 1 scale is added; the number of code quantity increases by multiple of all code point positions, if four

wheels

5, 3 code point positions, the number of code quantity increases by multiple = 3 times the number of scales increased by one plectrum, and the number of code quantity increases by 3 times on the basis of the original calculation of the same number of plectrums. The above is based on the fact that the requirements of a combination lock on the width of each piece under different conditions are sometimes very different, and it is very necessary to design the combination lock correspondingly to exert the corresponding effects of different widths. The dial is also based on a corresponding structure which can be relatively accurate, and the dial can be arranged at the same zone position of the dial, so that the password amount is enlarged by times or tens of times under the condition that a user only knows which scale position corresponds to each time without increasing memory points and operation actions; it is not difficult to imagine that for an illegal technical opener, it is sufficient to make it go to the detriment of the width of the pick, provided with a suitable number of graduations.

Operation and password setting basis: one code point position corresponds to one dial code, and one circle of code point positions are the total number of dial plates or a free wheel (or a driven wheel) dial bulges; the main shifting piece is connected with all the rotating wheels to achieve the necessary condition of uniform base point for shifting positioning and code matching, the main shifting piece carries the driving wheel to be axially movably connected with the free wheel and rotationally drives all the driven wheels to code point positions of the free wheel, when the code points are aligned, grooves on the inner peripheral end face of the free wheel correspond to the pin bolts, all the driven wheels are simultaneously brought to the base point of uniform starting of positioning and code matching, all the codes behind the driven wheels are respectively arranged on a circle of reverse dial, when each driven wheel is aligned with the code point position of the groove of the driving wheel (corresponding pin bolt), a specific shifting piece is selected to be an anchoring point pushed by clicking, the specific shifting piece is connected with the driven wheel in a one-to-one manner, all the specific shifting pieces can be simultaneously selected to be pushed by clicking, but the connected different corresponding driven wheels are respectively, all the driven wheels are respectively connected with the corresponding specific shifting pieces to be anchored, 8230, when all the grooves of the driven wheels are all aligned with the driving wheel and the driving wheel are aligned with the rotating shifting pieces, when the corresponding rotating shifting pieces are positioned in the grooves of the corresponding code positioning holes, the corresponding shifting pieces are positioned in a free dial, and the pin bolts can be rotated counterclockwise.

When code matching is carried out, a main shifting piece is selected to click and advance to be connected with a free wheel according to a specific direction (a solution is provided below), after the shifting piece is integrally rotated for more than one circle, all driven wheels are brought to a first code point position of the free wheel, a groove on the inner peripheral end face of the free wheel is positioned and corresponds to a pin bolt, and the code point position can also be simultaneously set to align a driven wheel and a groove of a driving wheel (corresponding to the pin bolt) (therefore, the relative thickness of the convex dial of the driven wheel corresponding to the main shifting piece is changed, the grooves of the driven wheel and the driving wheel can be aligned with each other only through the rotary connection in one specific direction, namely, the doubled code quantity is increased through the orientation without increasing any operation), and the corresponding first specific shifting piece is selected to be clicked and advanced to be connected with the convex dial of the corresponding driven wheel to be anchored, and then the grooves of the driving wheel can be aligned with each other and synchronously rotated (only by selecting a simple action of clicking and advancing the specific shifting piece, the code quantity is increased by about hundred times); then, the driver can only be reversely dialed back, the plectrum is reversely dialed back and rotated to a second password point position, namely, the driving wheel is mutually aligned with the groove of another set driven wheel, and a second specific plectrum corresponding to the driver is selected to be clicked and pushed to be connected with the corresponding driven wheel for convex dialing and anchoring, and then the driver and the driving wheel synchronously rotate \8230untilall the grooves of the set driven wheels and the driving wheel are completely aligned and all the specific plectrums are clicked, pushed and anchored respectively, then the plectrum is rotated to align the grooves of all the rotating wheels with the cotter, the cotter falls down, the lock core is rotated, and the lock is opened; when the lock is locked, the poking piece is rotated to enable the inclined surface of the rotating wheel (without the participation of the free wheel) to be lifted and locked with the pin bolt, and the poking piece is restored.

Because the peripheries of the driven wheel and the free wheel are provided with the convex dials in one-to-one correspondence with all the dials, the selection of a plurality of specific dials can be instantly, effectively and accurately realized, the dials are fast and efficient, the anchoring of the original alignment state is kept, although each specific dial can be respectively arranged at any position, each password point is unique to each selection of the dials (including the main dial) each time, the selection of the password positioning point within one circle of dial back is realized, even if only one password point is moved, and the simple action of clicking and pushing one corresponding specific dial can greatly increase the password number by hundreds to thousands times (depending on the number of dials); for general safety requirements only, taking the example of 50 dials, 2 slave wheels and their corresponding specific dials, the password =50 (selected master dial) × 2 (directional) × 50 (free wheel) × 49 (selected first specific dial) × 49 (password point) × 48 (selected second specific dial) × 49 (groove corresponding pin) =282.3576 yi |! It is sufficient to deal with any security risk, and if it is necessary to have higher security, it is only necessary to add a driven wheel and a specific combination of the dialing pieces, and the password amount can reach the level of several trillion.

The above-mentioned first operation for unblanking, the second, and the simple and easy operation of unblanking that can of unblanking every time afterwards: after the first or last unlocking, the plectrum is rotated to any position where the plectrum does not touch the free wheel convex dial in the locking direction, then all the plectrums are restored to the original position and do not need to be moved, therefore, when unlocking, the main plectrum and all the specific plectrums are clicked and pushed in, the original path (opposite to the rotating direction of the last 1 time) is restored to the unlocking position, the pin bolt can fall and be rotated to unlock, the locking is still operated as above, each time, the operation is very simple and convenient, the unlocking can be realized within 3 seconds! If you operate well, you can know that you have moved your lock as long as you can not open it. In fact, the chance of trial and error of any illegal unlocking in this case: with 50 dials, three main dials and two specific dials, the probability of success at one time =50 × 49 × 48 × 2 ÷ 2 ÷ 3 (three directional combination) × 49 (rotation amplitude)/one-minute =192.08 ten-thousandth, if the probability of success at one time =50 × 49 × 48 × 47 × 2 ÷ 2 ÷ 3 ÷ 4 (four directional combination) × 49 (rotation amplitude)/one-minute =2256.94 ten-thousandth for four dials, because the alignment structure of the groove is not destroyed only by selecting all dials at once, the rotation direction cannot be wrong, you get all positions of one turn, the walking is less, and the key is that you cannot know the mistake of the operation, and try one turn of the dials to fall into a random pairing mode irrevocably, even if there is not great possibility of recovering the original state. The half point of the safety degree is not reduced, the operation is extremely simple, and the number of memory points is 4-5. Most importantly, the reliability of the original hundreds of billions and billions of massive passwords still remains! Illegal operation can be realized, and timely notification can be realized.

The coded lock can adopt a single letter or a single digit to mark each plectrum, so that the operation and the memory are greatly simplified; the plectrum cylinder is eliminated, so that the selection and the reduction of the plectrum operation are easier, the arrangement quantity of the plectrums is greatly increased, and the detonation property of the code quantity is increased.

wheels

51, 52 brought to the free wheel 54 corresponds to the lock body base point 1B, so that the (U-shaped) groove 5c of the inner peripheral end surface of the free wheel 54 is firstly positioned to correspond to the bolt 4, at the moment, the position of the code point can also be simultaneously set, for example, the mutual alignment of the driven wheel 51 and the groove 5c of the driving wheel 53 (thereby, the relative thickness of the driven wheel convex dialing 51a and the corresponding main dialing piece 33 is changed, so that the driven wheel 51 and the groove 5c of the driving wheel 53 can be connected in a rotating way only from one specific direction, that the directional setting of any operation is not increased, the directional positioning is doubled, and the code amount of selecting specific dialing piece 31 is dozens of times,Cnamely, the code corresponding to the corresponding plectrum 3, such as the specific plectrum 31 is clicked and pushed, and is connected with the corresponding driven wheel convex plectrum 51b for anchoring, and then keeps mutually aligned and synchronously rotates with the groove 5c of the driving wheel 53; then the lock body can rotate within one reverse turn, and within one turn of reverse dial-back of the dial 3, until the second code point code 1 corresponds to the lock body base point 1b, namely, the driving wheel 53 is aligned with the groove 5c of another set, such as the driven wheel 52,Eis the corresponding second oneThe code of the specific poking piece 32 is clicked and pushed to be connected with the convex poking 52b of the driven wheel for anchoring, and then the code is synchronously rotated \8230alongwith the driving wheel 53, until all the set driven wheels are completely aligned with the grooves 5b of the driving wheel 53, and all the specific poking pieces are clicked, pushed and anchored respectively, F is to push and press the rotary reduction cylinder 6, and the code of the code point position where all the grooves 5c of all the aligned rotating wheels are aligned with the pin bolt 4 finally, when all the grooves are aligned with the pin bolt 4, the pin bolt 4 falls, the pin bolt 4 is separated from the lock cylinder 2, the lock cylinder 2 is rotated, and the lock is opened; when locking, the rotating reduction cylinder 6 is pressed to make the inclined surface of the rotating wheel 5 with the pin 4 rise and lock (the free wheel is still at the original position corresponding to the pin 4).

The aforesaid is the first operation of unblanking, the second time, and the simple and easy unlocking operation that unblanks every time afterwards and can: after the first or last unlocking is finished, the plectrum 3 is continuously rotated to any position where the plectrum 3 does not touch the free wheel convex dial 54b in the locking direction, all passwords can be restored, the plectrum 3 can be reset and does not need to be moved any more, therefore, when the lock is unlocked in each time, the main plectrum 33 and all

specific plectrums

31 and 32 \8230areclicked and pushed, the original way is restored to the unlocking position, the pin bolt 4 falls down, the lock cylinder 2 can be unlocked by rotating the lock cylinder, the operation is still the same as the above operation, the operation is very simple, and the lock can be unlocked only in about 3 seconds! If you operate well, you can know that you have moved your lock as long as you can not open it. Because the alignment structure of the groove 5c cannot be damaged only by simultaneously selecting all the poking pieces once, the rotation direction cannot be wrong, the walking is less and less, and the key is that the operation mistake can not be known, and the operation mistake can be found by one step, so that the operation can irretrievably fall into the random code matching mode even if the original state is not recovered. The half point of the safety degree is not reduced, the extremely simple operation of half circle is averaged, and the number of the memory points is 3-5. Most importantly, the security reliability inherent in the original hundreds and trillions of mass passwords is still maintained! Illegal operation can be realized, and timely notification can be realized.
