Tooth controlled coded mechanical lock core structure

Abstract

The invention discloses a code mechanical lock core structure with tooth control, comprising one or more code mechanisms, and a limit member and a control mechanism which are matched with the code mechanism; the code mechanism comprises a center coupled shaft arranged at a center plate and a coding part formed by a code adjustment disc, a ratchet wheel and a return buckle; a second projecting partmatched with a notch on the ratchet wheel is arranged at the limit member which is also provided with a second return spring; and the control mechanism comprises an elastic wheel toggling sheet and atooth control sheet which can be disengaged from the ratchet on the ratchet wheel, and axial return springs are respectively arranged at the wheel toggling sheet and the tooth control sheet. Codes ofa lock provided with the lock core structure of the invention are of two-dimensional structure, namely that a plurality of lock core structures can form transverse plurality-digit codes and each single lock core structure can be provided with longitudinal M-digit codes by the code adjustment disc. The code structure can form massive amount of codes by permutation and combination, thus the lock core structure has extremely large size of key and high confidentiality.

Description

technical field [0001] The invention belongs to locks, and in particular relates to a tooth-controlled password mechanical lock core structure. Background technique [0002] A common feature of existing mechanical combination locks is that one-dimensional coding is used in the password setting, that is, the numbers represented by the keys on the keyboard or the numbers on different dials are arranged and combined, and repeated codes cannot be used in each group of passwords. Therefore, the permutation and combination of the password is limited within a certain range, the key quantity is not high, and the security is affected. In addition, the passwords of the existing mechanical combination locks are all preset by the manufacturer, and the user cannot change the passwords if they are leaked. Contents of the invention [0003] The purpose of the present invention is to provide a tooth-controlled password mechanical lock cylinder structure with high key quantity and better ...

Problems solved by technology

[0002] A common feature of existing mechanical coded locks is that one-dimensional coding is adopted in the code setting, that is, the numbers represented by the keys on the keyboard or the numbers on different dials are arranged and combined, and repeated codes cannot be used in each group of codes. Therefore, the permutation and combination of the password is limited within a certain range, the key amount is not high, and the security is affected

In addition, the passwords of the existing mechanical combination locks are all preset by the manufacturer, if the passwords are leaked, the user cannot replace them.
