Description

Unlocking key

Technical Field

The utility model relates to a tool to lock technical field particularly, relates to an unblock key.

Background

In the field of anti-error safety, the blade-rotating computer key has become a great trend in the development of computer keys due to the advantages of convenience in carrying, simplicity in operation, good integrity, attractive appearance and the like. One main function of the computer key is an authorization mode, and the authorization mode of the early-stage rotating unlocking module is magnetic authorization of magnetic steel and soft magnetic marbles outside the unlocking blade. When the rotating computer key is located at the unlocking position and is inserted into the lock body of the lock, the computer key reads and verifies the identity information of the lock, the identity information of the lock passes verification, the driving module in the computer key pushes the linkage magnetic steel to push towards the surface of the lock, when the magnetic steel is located at the authorization position, the soft magnetic marble in the lock, which is opposite to the authorization magnetic steel, is attracted, the lock is located at an openable state, and the computer key can be rotated to unlock. The authorization mode is greatly influenced by factors such as temperature impact, magnetic fields and the like under the influence of external environment, the integral installation size is large, the structure is compact, the soft magnetic marble lock core is difficult to arrange, and the authorization mode is extremely difficult to arrange on a computer key and the lock core.

The existing computer key is realized by utilizing a rotary blade and a separated matching mode between an authorization assembly and a driving assembly inside the rotary blade to lock the computer key, particularly, when an unlocking blade is not rotated out, the driving assembly is separated from the authorization assembly, the driving assembly cannot drive the authorization assembly to move, when the unlocking blade is rotated out, the driving assembly is abutted against the authorization assembly, and the driving assembly can drive the authorization assembly to change the state. The commonly used action mode of drive assembly is gear rack of gear motor drive, because gear motor has the position auto-lock characteristic, when gear motor is in the switching lock process, the motor appears unusually or falls the electricity, leads to authorizing the subassembly and can not reset, authorizes the subassembly and can keep authorizing for the unblock blade can unblock the tool to lock as long as roll out, thereby produces the risk that the key becomes master key.
