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 compression latch includes a cylindrical housing (1). A locking shaft (2) is rotatably and axially movable in the housing. The locking shaft includes an axial free end (14) that engages a locking element (12). A cylindrical sleeve (3) engages an axial end of the locking shaft opposed of the free end. The sleeve includes an axially tapered annular sleeve slot (19) in which a shaft engagement pin (7) is engaged to cause axial movement of the locking shaft with rotational movement sleeve until the pin engages a slot end. After pin engagement with the slot end, further rotation of the sleeve causes rotation of the locking shaft. A cylindrical securing element (4) is rotatably engaged with and is axially movable relative to the sleeve. The securing element includes a circumferentially extending guiding recess (17) and a transversely extending latching recess (18). A securing element engaging pin (9) is engageable with the latching recess to prevent rotational movement of the securing element and the sleeve until the securing element is moved axially inwardly to disengage the pin and the latching recess.

A linear reciprocating-motion apparatus includes at least one movable member (10, 30) supported by a housing (90) and being capable of undergoing linear reciprocating motion in a range that includes a first position, a second position, and a third position; a stopper (50) supported by the housing to be displaceable between a blocking position that blocks the at least one movable member and a nonblocking position that does not block the at least one movable member, and is displaced to the nonblocking position in response to a specific operation; an intermittent mechanism (100, 200) that interacts with movement of the at least one movable member and assumes a specific state once every two times that the at least one movable member moves to the third position; and a switch (SW1) that, in response to the specific state, is switched from a disconnected state or a connected state to the other thereof.

A slide-and-swing wing system includes at least one rail profile. At least two wings, each displaceably mounted in the at least one rail profile via two support elements The at least one rail profile has a lateral outlet opening for unlatching a support element of a wing. One wing functions as a door leaf which, with all other wings in the latched state, is pivotable into the remaining opening. A closure mechanism makes it possible to prevent the door leaf from being opened and includes a drive, and also an operating part, via which the drive can be actuated. The door leaf is displaceable, via the drive, in the rail profile in the direction of the adjacent wing to such an extent that no support element of the door leaf is aligned with the outlet opening, thereby preventing a support element from coming out through the lateral outlet opening.

A locking device includes a sleeve, an actuator, and a stopper. The sleeve defines a receiving cavity and an outlet communicating with the receiving cavity. An inner wall of the receiving cavity defines a sliding groove and a stopping groove. The actuator is provided in the receiving cavity. One end of the actuator is inserted in the outlet, and another end of the actuator extends out of the receiving cavity. The stopper is provided on the actuator. The actuator is configured to be rotated to switch the stopper between the sliding groove and the stopping groove. When the stopper resists in the stopping groove, the actuator is fixed in the sleeve. When the stopper is switched to the sliding groove, the actuator is pressed to slide along the sliding groove and extend out of the outlet.
