Abstract
The invention provides a mechanical coded door lock, wherein a handle group, an unlocking group, a code lock group and a code searching group are arranged on a shell group; under the coordination of the unlocking group and the code lock group, the locking function of the coded door lock is released by shifting the unlocking group; in addition, in the code lock group, a bushing is pushed to separate from corresponding character wheel by pressing a press key, thereby rotating the character wheel and resetting the password; the code searching group is placed against the bushing of the code lock group and protrudes in the code searching tank of the corresponding bushing by means of a locating pin of the code searching group, in this way, the primary unlocking password can be obtained. The mechanical coded door lock not only can prevent the observant person from peeping and remembering the unlocking password of the coded lock, but also can allow the user to pass in and out repeatedly from the doorway provided with such door lock, thereby achieving the convenience in use.
Description
Technical field
The present invention is about a kind of mechanical password door lock, espespecially a kind of in order to be arranged on door-plate, and has concurrently and can look for former unblock number and can reset the new function unlocking number, and can remove the mechanical password door lock of locking function after door-plate is opened.
Background technology
Coded lock is a kind of common simple and easy lockset, each character wheel that user can lock by rotational password and to change its core be unlock or the state of locking, and to omit the necessity of carrying keys, thus increases the convenience on using.Therefore when coded lock is applied on door-plate, just can by this coded lock of adjustment for unlocking or locking state, reach control one and whether can drive the rotation of the handle of lock bolt: when coded lock unlocks, swing handle just can drive lock bolt and then opening-door plate; When coded lock is locked, then this handle can be made to drive locking bolt, the state making door-plate present closing.
But, general man memory is limited, or unblock number is easily forgotten under hasty, pass into silence and unlock the coded lock of number under cannot being unlocked, in order to remove its locking condition, unique mode destroys this coded lock and door-plate exactly, therefore for most user, the coded lock of prior art has the place of its inconvenience used;
Moreover when adjusting coded lock to released state after opening-door plate, user should first dial random character wheel, then enters the another side of door-plate, in case intentionally personage peeps and writes down the unblock number of this coded lock; But, once after dialling random character wheel, this coded lock just can present locking state and the position of the handle that locks, and makes this door-plate present again the state closed, so for must repeating to pass in and out the user of the access being provided with this door-plate, also there is the place of its inconvenience used.
