Abstract

The invention discloses a coded lock which comprises a lock body, a lock core and a lock bridge, the lock body is internally provided with a transition ring and a code wheel which are matched with each other and connected on the lock bridge in a crossing way, a spacing groove is arranged on the transition ring, a link mechanism which comprises a connecting bar and is used for matching the spacinggroove is arranged between the transition ring and the lock core, one end of the connecting bar is embedded in the lock core while the other end thereof is provided with a spacing bulge correspondingto the spacing groove, one side of the connecting bar close to the lock core is connected with an elastic component, the other end of the elastic component supports against the lock body and is used for pushing the connecting bar, and the rotation pivot of the connecting bar is fixed on the lock body for rotation. The invention can get the primitive code back under the situation of forgetting thecode, the lock core is opened by a decoding key and the code wheel is rotated until being not capable to rotate, the displayed code is the primitive code, at this time, the spacing bulge of the connecting bar is embedded in the spacing groove of the transition ring. The coded lock has simple structure, low cost and strong practicability, is hard to be damaged, and can get the code back conveniently.

Description

technical field [0001] The invention relates to a lock, in particular to a combination lock. Background technique [0002] Combination locks are more secure than ordinary tumbler locks. When the correct original password is known, the password of the combination lock can be changed at any time, and it is easy to carry and widely used. In practice, there are cases where the user forgets the password of the combination lock. After forgetting the password, the combination lock cannot be opened again. If it needs to be opened, it can only be opened by brute force to try each password one by one, which is time-consuming and laborious, which is very inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combination lock, which can effectively solve the time-consuming and labor-intensive problem that the user needs to use brute force cracking to debug the passwords one by one after forgetting the password of th...
