Abstract:
A dual-lock type padlock has a double reminding function includes a housing, a catch member, a shackle, a locking mechanism, and an indicator. The dual-lock type padlock is opened by either one of a key and a code. Thus, the indicator is movably mounted on an outer face of the housing or the catch member which is formed with a first mark and a second mark in the corresponding positions, so that the user can judge if the padlock has been unlocked by inspecting the position of the first mark or the second mark, and can also feel the position of the indicator by touching the indicator so as to judge if the padlock has been unlocked, thereby facilitating the blind people operating the padlock.
