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.
Claims20
An unlocking and locking method of a cabinet lock, including unlocking and locking operations;
- wherein,
- a second lock rod of a lock rod is arranged in an X-axis direction, so that the lock rod is rotatably arranged around the center line of the second lock rod as an axis;
- and the first lock rod and the second lock rod are arranged at an included angle;
- the unlocking operation includes:
- applying a force to the lock rod or a locking assembly so that the lock rod has a relative displacement in the X-axis direction with respect to the locking assembly, the relative displacement including being relatively close or far away to transition the lock rod from a locked state to a rotatable state;
- and
- keeping the lock rod in a rotatable state and rotating the first lock rod from a locked position to an unlocked position to realize the unlocking operation;
- and
- the locking operation includes:
- placing the lock rod in a rotatable state and rotating the first lock rod from the unlocked position to the locked position;
- wherein the first lock rod may be rotated in a direction reverse to the rotation direction upon unlocking or may continue to be rotated in the unlocking direction to reach the locked position;
- and
- displacing the locking assembly and the lock rod relative to each other in the X-axis direction along a direction opposite to the unlocking direction, and engaging the second lock rod with the locking assembly, so that the rotation of the second lock rod around the X-axis direction is locked by the locking assembly and the first lock rod cannot be rotatably arranged, thus locking the cabinet.
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 which are arranged at an included angle;
- 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;
- and
- 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.
