A locking system has a housing and a spring positioned in a body. The system has a locking element on which a spring is attached such that the locking system is inside the housing, and provides locking. At least one fixing element is engaged with the housing, and enables the locking element to be fixed to the housing. At least one guide element is combined with the locking element, and allows the spring to remain on the locking element and the locking element to move in the housing. At least one ring is connected with the guide element and the locking element and ensures the fixation of the locking element to the housing.

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.

An example trim generally includes an escutcheon, an indicator plate, a cam, and a backplate. The indicator plate is movably mounted in the escutcheon, and has a first position in which a first indicium is aligned with an escutcheon window of the escutcheon, and a second position in which a second indicium is aligned with the escutcheon window. The cam is rotatably mounted in the escutcheon for rotation between a first handing orientation and a second handing orientation. The cam is operable to move the indicator plate between the first position and the second position when the cam is in each of the handing orientations. The backplate is coupled to the escutcheon and at least partially encloses the indicator plate within the escutcheon. The cam is operable to rotate between the first handing orientation and the second handing orientation while the backplate remains coupled to the escutcheon.

A fixture lock is provided to lock two movable parts of a fixture so that one part may not be moved relative to another part to gain access to a receptacle formed in the fixture. The fixture lock could be used to lock a cabinet drawer in a closed position in a cabinet base to block access to a storage region formed in the cabinet drawer.

An access-control system is provided for a door lock that is associated with a door and a rotatable doorknob. The access-control system includes a doorknob cover.

A lock knob assembly includes a knob body, a cover and a coupling member. The knob body is provided for covering a lock cylinder, and the cover is provided for covering the knob body. The lock knob assembly utilizes the coupling member to selectively couple the cover and the knob body, thus allowing the cover to couple with or separate from the knob body.
