Push-button machine combination lock and unlocking lock validation method

Abstract

The invention discloses a combination lock and an unlocking lock validation method. The unlocking lock validation method comprises the steps of longitudinally recording an unlocking password string and setting the password string; after the unlocking password string is recorded, transversely comparing the unlocking password string with the set password string; if the unlocking password string is matched with the set password string, driving an unlocking lever to unlock; and if the unlocking password string is not with the set password string, not driving the unlocking lever to unlock. The combination lock and the unlocking lock validation method have the beneficial effects that source and strength of each input password can be balanced, whether the unlocking password string is correct or not can be validated only after the actions of the input passwords are completely finished, and whether each password is correct or not cannot be known during the period of inputting the passwords, so compared with a traditional push-button machine combination lock, the security and the reliability are obviously improved.

Description

Technical field [0001] The invention relates to a mechanical code lock, in particular to a button type mechanical code lock and an unlocking verification method. Background technique [0002] At present, there are many types of existing push-button mechanical code locks. For example, the authorization announcement number CN201187187Y discloses a push-button mechanical code lock cylinder, which has the advantages of strong confidentiality, high reliability, no electricity and no keys. Therefore, it is also a market The common button type mechanical code lock on the However, this patent and many existing mechanical combination lock cylinders have safety hazards. When the wrong key sequence number is pressed, the linkage mechanism such as the serial number coding block will automatically reset. It is precisely because the mechanism will automatically reset when the key is wrong. Personnel with professional skills can judge from the experience of various aspects such as sound and st...
