Key code fused A1 type safe lock for eliminating 12 hidden dangers by multiple protections

Abstract

The invention discloses a key code fused A1 type safe lock for eliminating 12 hidden dangers by multiple protections, and relates to a mechanical coded lock and a key lock for a safe. The double locks are fused and controlled mutually, a knob is in engaged and disengaged fit with the coded lock, and a counterweight unlocking plate linkage body is linked with an elastic buffer body; dynamic balance adjustment is performed on the coded lock, so that 10 hidden dangers comprising frictional opening, percussive opening, tested dynamic balance opening and coded full-test opening of the coded lock and frictional opening, percussive opening, code variable full-test opening, universal key type opening, oscillator type opening and integral locking full-test opening of the key lock are eliminated; meanwhile, inherent mutual opening hidden danger and reopening hidden danger of the key lock are simultaneously eliminated; according to 13.6 million times of code variables, the lock becomes a general mechanical safe lock with strongest confidentiality in the ancient and modern in China and abroad, and is to become an upgraded product in the industry; and the lock has simple structure, and is suitable for safes used in national defense, scientific research, public security, financial institutions and households.

Description

Technical field: [0001] The invention relates to a safe lock, in particular to a mechanical combination lock and a mechanical key lock used in the safe. technical background: [0002] I have obtained the right of the prior invention "mechanical double-set lock for external separation and internal closure" (patent number: 200620113174X), the performance of preventing technical opening is not comprehensive, and there are still hidden dangers due to the lack of deep consideration. At the same time, its technology is relatively complicated, and there are many consumables, which do not meet the requirements of a low-carbon society. At present, a large number of electromechanical safe locks combined with general-purpose electronic combination locks and key locks flooding the market are not safe when power is off, malfunctions, forgotten passwords, or normal use. At the same time, the operator can turn a blind eye to the electronic combination lock, discard it and only use the key ...

[0002] I have obtained the right of the prior invention "mechanical double-set lock for external separation and internal closure" (patent number: 200620113174X), the performance of preventing technical opening is not comprehensive, and there are still hidden dangers due to the lack of deep consideration. At the same time, its technology is relatively complicated, and there are many consumables, which do not meet the requirements of a low-carbon society. At present, a large number of electromechanical safe locks combined with general-purpose electronic combination locks and key locks flooding the market are not safe when power is off, malfunctions, forgotten passwords, or normal use. At the same time, the operator can turn a blind eye to the electronic combination lock, discard it and only use the key to open the safe, especially the thief can completely avoid the electronic combination lock and directly use the key to open the safe, causing the electronic combination lock to be useless. Lost function, the combination of this double lock is extremely unreasonable, great hidden danger
