Abstract
The invention belongs to the technical field of daily necessities, and particularly relates to an unlocking and locking method of a cabinet lock and a cabinet safety lock. During unlocking, a lock rod is displaced relative to a locking assembly to release the locking of the lock rod, and a first lock rod is rotated to an unlocked position. During locking, the first lock rod is rotated to a locked position and the locking assembly is engaged with the lock rod to lock the second lock rod. The method and the cabinet safety lock have a novel operating mode, have a firm structure, are convenient to use, and can effectively avoid unauthorized operation by children.

A cabinet safety lock, including a lock body, a lock rod and a locking assembly, the lock rod and the locking assembly being arranged on the lock body;
- wherein,
- the lock rod includes a first lock rod and a second lock rod substantially perpendicular to each other;
- and the second lock rod is rotatably arranged on the lock body around the X-axis direction as an axis and thus the lock rod is rotatably arranged on the lock body, and the locking assembly is fitted to the second lock rod to lock or unlock the rotation of the lock rod;
- the second lock rod is provided with a first locking member including a first locking unit;
- the locking assembly includes a locking member configured to be non-rotatably disposed on the lock body, the locking member is internally provided with a locking cavity for the first locking member to be fitted therein, and the locking cavity is internally provided with a second locking unit;
- and at least one of the first locking unit and the locking member is movably arranged in the X-axis direction;
- the first locking unit cooperates with the second locking unit so that the rotation of the second lock rod relative to the lock body is locked;
- and the first locking unit is displaced relative to the locking member in the X-axis direction to disengage the first locking unit from the second locking unit, so that the second lock rod returns to be rotatably arranged relative to the lock body;
- and
- the first locking unit and the second locking unit are respectively a groove and a protrusion matching each other, the second lock rod further includes a rotating member which is a circumferential groove arranged along the surface of the second lock rod, and the second locking unit is a protrusion arranged in the locking cavity;
- and after the first locking unit is displaced relative to the locking member in the X-axis direction, the second locking unit is fitted into the rotating member.
