Mechanical password lock capable of automatically clearing password
The invention discloses a mechanical password lock capable of automatically clearing a password. The mechanical password lock capable of automatically clearing the password comprises a shell, a lock cylinder assembly which can rotate relative to the shell is arranged on the shell in a penetrating manner, and one end of the lock cylinder assembly is fixedly connected with a lock plate; a first fixing pin is further fixedly arranged in the shell, multiple character wheel cores are arranged on the first fixing pin in a sleeving manner, each character wheel core is provided with a character wheel which can drive the character wheel core to rotate together or rotate relative to the character wheel in a sleeved manner, and multiple code characters are arranged on the outer surfaces of the character wheels; and a moving shaft which can move left and right and rotate along with rotation of the lock cylinder assembly is further arranged in the shell, multiple pawls are fixedly arranged on the moving shaft, the pawls correspond to the character wheels and can be connected with character wheel cams on the character wheels in an abutted manner, and the character wheel cams are logarithmic spiral cams. When the password lock is opened, due to the fact that the pawls act on the character wheel cams on the character wheels to make the character wheel cams rotate continuously, the unlocked password lock does not display the correct password, the correct password can be automatically hidden no matter the lock is unlocked or locked, traces are not left, and the secrecy performance is good.
