Problems solved by technology

Among them, the cracking of passwords due to technical loopholes is the primary problem. For example, a button-type mechanical combination lock with application number 200410029812.5 has differences in the structure and working principle of the interlocking parts in the lock caused by correct buttons and wrong buttons. These differences will be more or less detected by the user through the touch and hearing, so as to crack the code

Abstract

The invention discloses a mechanical coded lock based on a three-layer coaxial nested structure. The mechanical coded lock comprises digital keys marked with numbers, a password loading system for setting passwords and capable of moving in a straight line to provide driving force for a spring bolt, a drive system for unlocking and locking the password loading system, and a resetting system for recovering the coded lock into an initial state, wherein the password loading system is provided with a sliding shaft; the driving force of the drive system is provided by the digital keys during unlocking; the drive system is provided with a drive shaft inserted into the sliding shaft; the resetting system is provided with a resetting main shaft inserted into the drive shaft. The mechanical coded lock based on the three-layer coaxial nested structure has the advantages of structural modularization, part standardization, low pressing force, safety and reliability, low production cost and wide application range.

Description

technical field [0001] The invention belongs to the technical field of combination locks, in particular, the invention relates to a mechanical combination lock based on a three-layer coaxial nesting structure. Background technique [0002] With the rapid development of modern society, the use of locks is becoming more and more extensive, and everyone needs to carry more and more keys. If the keys are forgotten or lost, it will cause great inconvenience. And there are many deficiencies in the push-button type mechanical combination lock at present. Among them, the cracking of passwords due to technical loopholes is the primary problem. For example, a button-type mechanical combination lock with application number 200410029812.5 has differences in the structure and working principle of the interlocking parts in the lock caused by correct buttons and wrong buttons. These differences will more or less be detected by the user who presses the key through the touch and hearing, so...
