Description

Coded lock and coded box with coded lock Technical Field The utility model relates to a lockset, in particular to a coded lock and a coded box with the coded lock. Background At present, most of case locks are generally provided with coded locks, but most of coded lock bodies are too complex in structure, and the locking limitation of the zippers can be realized only for some cases with the zippers through lock hooks. The luggage without the zipper is generally locked by adopting a buckling structure, and the buckling of the male buckle and the female buckle is realized, so that the buckling lock used on the luggage needs to be simultaneously pressed by two hands to unlock when the luggage is unlocked, and the unlocking is inconvenient. Disclosure of Invention In order to overcome the defects in the prior art, the utility model aims to provide a coded lock and a coded box with the coded lock. The coded lock comprises a mounting plate, wherein a left lock rod, a right lock rod, a coded wheel assembly, a limiting plate and a button for driving the left lock rod and the right lock rod to move simultaneously are arranged on the mounting plate, one end of the limiting plate is provided with a limiting bulge, and the limiting bulge is positioned between the left lock rod and the right lock rod; when the password wheel assembly inputs a correct password, the limiting protrusion can tilt to cancel the movement restriction on the left lock rod and the right lock rod, and the button is pressed to drive the left lock rod and the right lock rod to move and unlock simultaneously.
