Key type mechanical password lock and password setting method

Abstract

The invention discloses a key type mechanical password lock and a password setting method. The password lock comprises a lock shell as well as a key transmission system, a resetting system and a tongue control system, wherein the key transmission system, the resetting system and the tongue control system are arranged in the lock shell; the key transmission system comprises a keyboard component and a password carrying wheel plate component; each key body of the keyboard component is corresponding to each password carrying wheel plate of the password carrying wheel plate component; each key body is divided into two key branches extending to two plate surfaces of the corresponding password carrying wheel plate, so that the two key branches are respectively matched with the two plate surfaces; a plurality of wheel plate holes are formed in each password carrying wheel plate; pin shafts are inserted in the wheel plate holes; the extending directions and the combinations of the pin shafts on the two plate surfaces bear password information; when pushing wheel blocks on the key branches can apply forces to the corresponding pin shafts during pushing the keys, the password carrying wheel plate component is pushed to rotate in a positive or negative direction; and the resetting system is driven by a linking mechanism to store energy and the tongue control system is driven by the linking mechanism to act; and the key type mechanical password lock disclosed by the invention has the advantages of modularized structure, standardized part, small pressing force, safety, reliability, low production cost and wide application range.

Description

technical field [0001] The invention relates to a combination lock, in particular to a key-type mechanical combination lock and a method for setting the combination thereof. 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 be more or less detected by the user through the touch and hearing, so that the password can be easily cracked through the tou...

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 that the password can be easily cracked through the touch or hearing; in addition, the current push-button mechanical combination lock technology is difficult to realize the combination of modules according to the use environment and purpose requirements. The free change of the number of digits and the number of keys and the free selection of the key amount make the push-button mechanical combination locks unable to meet the diverse needs of the market at low cost; moreover, most of the current push-button mechanical combination locks have complex internal structures and There are many non-standard components as the premise to meet the high key volume, which often requires a large key force to effectively open, which seriously affects the satisfaction of the user's hand feeling and the reliability of the operation; there are too many keys, so It is difficult to realize touch typing and there are traces of keystrokes, so there is a common worry that the password will be cracked
