Abstract: An automatic messy code character wheel coded lock includes a housing and a lock case capable of rotating with respect to the housing provided on the housing in a penetrating mode. A lock cylinder assembly is provided in one end of the lock case, and a lock piece is connected to the other end of the lock case. A character wheel shaft is provided in the housing. Several bushings are sleeved on the character wheel shaft. Each bushing is sleeved with a character wheel capable of driving the bushing to rotate together or rotate relatively. Several code characters are provided on a side wall of the character wheel. Each character wheel is provided with a pair of character wheel magnets having opposite poles, and the character wheel shaft is provided with one character wheel shaft magnet corresponding to each pair of character wheel magnets.

Abstract: Disclosed in the present invention is a novel code wheel combination lock, comprising a knob and a face plate that can rotate with respect to each other, a lock tongue, and a code wheel assembly.

Abstract: Disclosed is an improved password lock, comprising a housing, a lock case, a password box, and a tongue; the housing is composed of a shell and a panel; the panel is fixed on the top surface of the shell to form an accommodating cavity of the housing; the middle part of the lock case is rotatably sleeved at one side of the housing; the password box is installed in the accommodating cavity of the housing, and the password box is cooperatively linked with the lock case; and the tongue is fixedly sleeved on a penetrating end, penetrating through the housing, of the lock case. The lock case can drive a slide block in the password box to move horizontally for changing a password, and therefore the operation is convenient.
