Problems solved by technology

[0002] There are many fatal flaws in traditional mechanical digital locks, such as: 1. It cannot be operated without light; The disk is easily damaged; 4. It is easy to open with low encryption technology; 5. It is difficult to reset the password, etc.
Chinese patent 200820218876.3 provides a mechanical digital lock that can change the password and has a large amount of encryption, but correspondingly it also needs to have a matching key. Among them, the marble key only has the function of opening and closing the lock. Any implications remain for further study

Abstract

The invention relates to an unlocking key of a mechanical digital lock. The variable-code key with cylinder shifting teeth is characterized in that: a key rod is provided with multiple shifting tooth holes; the cylinder shifting teeth are mounted in partial or all shifting tooth holes, freely stretch / withdraw relative to the shifting tooth holes, and can switch in different shifting tooth holes; and only one cylinder shifting tooth can be mounted in the shifting tooth holes on the same circumference of the key rod. With a simple structure, the variable-code key provided by the invention not only realizes the intrinsic locking / unlocking function of a key, but also can change the combination of the cylinder shifting teeth and the shifting tooth holes on different positions of the key; and moreover, a novel key component integrating the encryption function and the key locking / unlocking function is created, two simple and convenient cylinder shifting tooth structures are provided, and more other cylinder shifting teeth with the same concept are also applicable. The variable-code key is simple to operate, convenient to use and high in security and suitable to be matched with the concealed digital locks of various safety boxes and security doors.

Description

technical field [0001] The invention relates to an unlocking key of a mechanical digital lock. Background technique [0002] There are many fatal flaws in traditional mechanical digital locks, such as: 1. It cannot be operated without light; The disk is extremely easy to destroy; 4. It is easy to open with low technology; 5. It is difficult to reset the password and so on. Chinese patent 200820218876.3 provides a mechanical digital lock that can change the password and has a large amount of encryption, but correspondingly it also needs to have a matching key. Among them, the marble key only has the function of opening and closing the lock. Any implications remain for further study. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention provides a tumbler shifting teeth variable code key, which has an ingenious structure, realizes good cooperation with the key shaft, realizes the function of unlocking and locking, and can us...
