Description

  The present invention relates to a lock, and more particularly to a lock that is provided on a door, a bag or the like and is opened and closed with a password.

  In general, locks are roughly divided into two types: electronic and mechanical.

  Electronic locks are easily unlocked, but mechanical locks do not have such disadvantages.

  The mechanical lock is divided into a key type and a code number type.

  The key type cannot be unlocked without an appropriate key. For this reason, when the key is forgotten, the situation that unlocking occurs.

  The password type lock is relatively convenient because it can be easily unlocked if the password is stored, and does not have the above-mentioned problems.

  At present, the code-type lock commonly found in the market is controlled by moving a plurality of number tires to unlock the lock.

  However, each of the number tires has only ten numbers from 0 to 9, and can achieve the purpose of unlocking either clockwise or counterclockwise.

  Therefore, there are few combinations of arrangement | sequences of a PIN code, and a PIN code is easily decoded and unlocked.

  This invention makes it a subject to provide the lock which cannot be unlocked easily and can prevent theft.

  The lock rod 7 is provided for drilling in the keyhole 16, and at least one or more grooves 70 are provided on the lock rod 7, and are provided for fitting the outer end edge portion of the tumbler 20.

  When the concave portions 311, 321, 511, 521 of the disk bodies 31, 32, 51, 52 in the front disk set 3 or the rear disk set 5 are in positions that do not correspond to the gap 110, the convex portion 22 of the tumbler 20. Comes into contact with the outer peripheral edge of the disc body, and the tumbler 20 cannot move in the hole 15.

  Therefore, the outer edge portion of the tumbler 20 is fitted into the groove 70 of the lock rod 7 and is locked.

  When the front disk 4 is rotated clockwise or counterclockwise and the first disk body 31 is rotated in conjunction with the shaft tube 30, the first disk body 31 moves the protrusion 322 through the protrusion 312, The two-disc body 32 rotates.

  When the front disk 4 rotates to the first correct password, the recess 321 of the second disk body 32 moves to a position corresponding to the gap 110.

  Next, when the front disk 4 is rotated clockwise or counterclockwise to rotate the second code number to the correct position, the concave portion 311 of the first disk body 31 moves to a position corresponding to the gap 110.

  When the rear disk 6 is rotated clockwise or counterclockwise and the third disk body 51 is rotated in conjunction with the shaft 50, the third disk body 51 moves the convex part 522 through the convex part 512, and the fourth The disk body 52 rotates.

  When the rear disk 6 rotates and the third personal identification number reaches the correct position, the concave portion 521 of the fourth disk body 52 moves to a position corresponding to the gap 110.

  When the rear disk 6 rotates clockwise or counterclockwise and the fourth password reaches the correct position, the recess 511 of the third disk body 51 moves to a position corresponding to the gap 110.

  Therefore, when the concave portions 311, 321, 511, and 521 of the first, second, third, and fourth disk bodies 31, 32, 51, and 52 all move to positions corresponding to the gap 110, the convex portion 22 of the tumbler 20 becomes the gap 110. Then, the tumbler 20 moves in the recesses 311, 321, 511, 521 and moves into the hole 15 to be unlocked.

  In the embodiment of the present invention, the number of disk bodies of the front disk set 3 and the rear disk set 5 can be increased or decreased as necessary.

  As the number of disc bodies decreases, the number of combinations of passwords for unlocking decreases, and as the number increases, the number of combinations increases, making it difficult to decode the passwords and improving safety.

  Whether or not the front disk 4 and the rear disk 6 of the present invention are used can be determined depending on the actual use situation.

  For example, when the disk is always unlocked for a short time, if one disk is rotated in advance to an accurate number, the other disk can be unlocked only by rotating to an accurate number.

  If the time interval for unlocking is relatively long, the two sets can be simultaneously rotated to the correct number and unlocked.

  In addition, since the security code numbers of the two discs can be owned by two persons, the two persons must have the same number when unlocking, so that the safety can be further improved.
