Door lock permitting easy change in lock core assembly orientation

A door lock comprising:

• a driving device including an outer spindle pivotable about a pivotal axis, with the driving device adapted to be mounted to a door having a first end face and a second end face opposite to the first end face, with the door further including a first side extending between the first and the second end faces, and with the outer spindle having a distal end located on an outer end of the first side of the door;
• a latch device operably connected to the driving device, with the latch device including a latch, with pivotal movement of the outer spindle causing movement of the latch between a latching position and an unlatching position, and with the latch device configured to be mounted to one of the first and second end faces of the door;
• an outer handle including an outer end and an inner end spaced from the outer end along a longitudinal axis of the outer spindle, with the outer handle further including a compartment extending from the outer end towards but spaced from the inner end of the outer handle, with the compartment including an inner periphery having a groove, with the outer handle further including an axial hole extending from the inner end of the outer handle and intercommunicating with the compartment, and with the outer handle coupled to and jointly pivotable with the outer spindle;
• a mounting member rotatably mounted in the compartment of the outer handle, with the mounting member including a first end face and a second end face spaced from the first end face along the longitudinal axis, with the mounting member further including a first hole extending from the first end face through the second end face and aligned with the axial hole of the outer handle, with the mounting member further including a second hole extending from the first end face through the second end face, and with the second hole located on a side of and intercommunicated with the first hole;
• a positioning member movably received in the groove of the outer handle, with the positioning member permitting the mounting member to pivot about the pivotal axis and preventing the mounting member from moving relative to the outer handle along the longitudinal axis;
• and
• a lock core including a first portion and a second portion adjoining and extending parallel to the first portion, with the lock core detachably engaged with the mounting member,
• with the lock core engaged with the mounting member, the first portion of the lock core is received in the first hole of the mounting member, and the second portion of the lock core is received in the second hole of the mounting member, preventing the mounting member from pivoting about the pivotal axis relative to the outer handle to change a positional relationship between the first and second holes of the mounting member,
• with the lock core disengaged from the mounting member, the mounting member is pivotable about the pivotal axis relative to the outer handle,
• with the latch device mounted to the first end face of the door, the second portion of the lock core is located right below the first portion of the lock core in a vertical direction perpendicular to the pivotal axis, and
• with the latch device mounted to the second end face of the door, the second portion of the lock core is located right below the first portion of the lock core in a vertical direction perpendicular to the pivotal axis.
