Abstract

The invention discloses a safety lock, which comprises a lock core box, a handle, a secondary lock core, a master lock core, a square column-shaped controller, a unidirectional rotating shaft, a bolt and a restorer. In the safety lock, a double lock core design is adopted; the safety of the lock is improved through the deepening of key indents, and the design of circular grooves formed above and below a hollow hole of the master lock core; and the lock cores can be conveniently and rapidly replaced through the change of a built-in key bar. Meanwhile, the same built-in key bar is arranged, so that a key with one type of indents can unlock a plurality of locks; therefore, the number of keys carried by a user is reduced. The safety lock overcomes the defects that the conventional lock has low safety performance and is difficult to replace, meets the requirement of modern production and living and has wide market development prospect.
