Mechanical key puzzle lock

Abstract

The invention discloses a mechanical button coded lock which finishes locking and unlocking through an external button driving an internal connected column hook, comprising a support saddle (1), cipher buttons (2), an upper cover plate (10), a lower cover plate (11), a lock plunger (5), a bolt (6) and a lock catch (20), wherein, a knob (16) is opened, cipher column hooks (4) are arranged inside the support saddle (1), the cipher column hooks (4) are in one to one correspondence with the cipher buttons (2); two clamped and hung hook plates (8), (9) are arranged inside the support saddle (1); the cipher column hook (4) penetrates the two clamped hook plates (8), (9); the clamped hook plate (8) and the clamped hook plate (9) are parallel; the cipher buttons (2) totally have 11 buttons, including zero to nine and a 'full stop'. The invention has the advantages of multilayer clamping and hanging, multiple group ciphers, reusing availability of the same button, concealed inputted buttons, etc. The invention is further improved in the aspects of cipher group quantity and security.

Description

technical field [0001] The invention relates to a mechanical lock, in particular to a mechanical key coded lock which is locked and unlocked by driving an inline column hook through an external key. Background technique [0002] At present, the existing mechanical key combination lock overcomes the shortcomings of the key carrying the key and being easy to lose, being copied, and the electronic lock requires electricity and cannot be used in harsh environments or is easily damaged by impact. The mechanical combination lock with the patent No. 89107364.7 is just This equipment technical scheme is disclosed. However, there are unreasonable mechanical structures and single working performance in the existing combination locks, so that the number of password groups is small, and its sequence and arrangement are easy to be mastered by outsiders to crack the password, and the same key cannot be reused, so it is difficult to be used. Accepted by users who require a higher security...
