The end of the yoke 63 abuts against the corresponding character wheel 43. When the end of the locating pin 62 protrudes into one of the positioning grooves 433 of the character wheel 63, one of the pattern areas 432 of the character wheel 63 Just facing the outside of the outer casing 11, the user can unlock by means of arranging the numbers or symbols of the pattern area 432 on each character wheel 43, and by means of the positioning pin 62 and the positioning groove 433 of the character wheel 43. The cooperation can increase the hand feeling of the user when dialing the character wheel 43, so that the character wheel 43 can be rotated to each position to facilitate unlocking.

Referring to FIG. 9 , firstly, when the mechanical code door lock of the present invention is to be unlocked, each character wheel 43 of the combination lock set 40 is respectively rotated to a preset unlock number, so that the sleeve 42 is The alignment bump 422 is located between the alignment portion 412 of the lock cylinder 41. At this time, as shown in FIG. 10, when the user turns the lever 33 to drive the tooth portion 312 of the click ring 31 toward the handle. When the interlocking gear 27 of the group 20 rotates, the latching ring 31 can force the latching cylinder 41 to move upward, and on the other hand, the toothed portion 312 of the latching ring 31 can be meshed with the interlocking gear 27, The lock body 21 is driven to unlock the lock body 21 and the lock bolt 22, and the user can rotate the outer handle 23 to open the door panel. Further, since the handle set 20 has passed through the lock group 40 The unlocking group 30 is unlocked, so that the user can discard the position of each character wheel 43 to prevent the person concerned from peeking and recording the unlocking number of the mechanical code door lock, and can repeatedly enter and exit the door panel. Access to the door, to achieve the convenience of use; conversely, when you want to the mechanical password door When the lock is locked, the lock lever 26 of the handle set 20 is first rotated by the inside of the door panel to drive the lock body 21, so that the lock body 21 and the lock bolt 22 are locked, and then the lock lock group is respectively respectively The 40-character wheel 43 is turned to the position of the unlocking number. At this time, since the alignment projection 422 of the sleeve 42 is located in the through slot 414 of the locking post 41, it is engaged with the alignment portion of the locking post 41. Between the positioning protrusions 413 of the 412, at this time, since the locking post 41 cannot move up and down, the user cannot drive the locking ring 33 to drive the locking ring 31, and the locking body cannot be further driven. 21, so it can achieve the purpose of closing the door.

Referring to FIG. 11 further, when the unlocking password is to be reset, the button 45 of the number lock group 40 can be pressed in the unlocked state of the mechanical code door lock, thereby pushing the sleeve 42 down and compressing. The sleeve elastic member 44 causes the pair of the protrusions 423 of the sleeve 42 to be disengaged from the opposite protrusions 431 of the character wheel 43. At this time, the character wheels 43 can be individually rotated to reset the password; after the setting is completed, The button 45 is released, and the sleeve 42 is pushed up by the sleeve elastic member 44 to move the pair of the protrusions 423 of the sleeve 42 between the two adjacent pairs of the projections 431 of the character wheel 43. , complete the password reset action.

When the unlocking password is inadvertently forgotten, the user must first use the key to drive the lock core 25 of the handle set 20 to drive the lock body 21, so that the lock body 21 and the lock bolt 22 are unlocked to achieve the opening. The purpose of the door panel, and then further, as shown in Figures 12 and 13, after entering the inside of the door panel, the driving member 55 of the group 50 is rotated to drive the ejector 51 to move along the direction in which the slot 511 extends. And pushing the alignment pin 53 to move toward the combination lock group 40. At this time, the character wheel 43 is turned and the sleeve 42 is driven, and when the numbering groove 424 of the sleeve 42 corresponds to each of the alignment pins 53, When the alignment pin 53 further protrudes between the corresponding slots 424 of the sleeve 42, the character wheel 43 and the sleeve 42 are located at the unlocked position, so that the previously inadvertent forgetting is known.
