A buckle assembly includes a first buckle component, a second buckle component and an operating component. The first buckle component includes a locked portion. The second buckle component includes a locking portion. The locking portion engages with the locked portion along a lateral direction of the buckle assembly when the second buckle component is mated with the first buckle component along a mating direction. The operating component is partially embedded in and partially exposed out of the second buckle component. The operating component is slidable relative to the second buckle component. The operating component drives the locking portion to move away from the locked portion for disengaging the locking portion from the locked portion during a sliding movement of the operating component relative to the second buckle component. The present invention has advantage of saving labor and easy operation.

A buckle assembly can include a first buckle, a second buckle, and an operating component. The first buckle component can include a locked portion. The second buckle component can be configured to be engaged with the first buckle component, and the second buckle component can include a locking portion engageable with the locked portion. The operating component can be partially embedded in the second buckle component and partially exposed out of the second buckle component. The operating component can be slidable relative to the second buckle component such that sliding movement of the operating component relative to the second buckle component causes disengagement between the first buckle component and the second buckle component. The operating component can include an abutting portion, and the abutting portion can abut against the locking portion to resiliently deform the locking portion during the sliding movement of the operating component.

An inserting buckle includes an insertion piece, a buckle body, an ejection member, a first pressing buckle and a second pressing buckle. The second pressing buckle movably disposed in the cavity and moved toward or away from the first pressing buckle; the second pressing buckle is driven back by a second elastic member; a buckle hole is formed between the first pressing buckle and the second pressing buckle; the connection portion is inserted into the cavity and is locked in the buckle hole; the first pressing buckle and the second pressing buckle are simultaneously pressed to enlarge an width of the buckle hole, the connection portion is separated from the buckle hole, the ejection member ejects the connection portion out of the cavity. The operation of separating the buckle body and the insertion piece only needs to simultaneously press the first button and the second button with one hand.

A buckle includes a tab having a first side opposed to a second side and a receiver having a first side opposed to a second side. A first pair of pawls is pivotally connected to the first side of the tab. A cavity is defined in the receiver between the first and second sides of the receiver and configured to receive the first and second sides of the tab. The first pair of pawls has a locked position in which the first pair of pawls is engaged with the receiver to prevent movement of the tab with respect to the receiver and a released position in which the first pair of pawls permits movement of the tab with respect to the receiver. A first button on the first side of the receiver has a released position that moves the first pair of pawls to the released position.

An inserting buckle comprises an insertion piece, a buckle body, an ejection member, a first pressing buckle and a second pressing buckle. The second pressing buckle movably disposed in the cavity and moved toward or away from the first pressing buckle; the second pressing buckle is driven back by a second elastic member; a buckle hole is formed between the first pressing buckle and the second pressing buckle; the connection portion is inserted into the cavity and is locked in the buckle hole; the first pressing buckle and the second pressing buckle are simultaneously pressed to enlarge its width of the buckle hole, the connection portion is separated from the buckle hole, the ejection member ejects the connection portion out of the cavity. The operation of separating the buckle body and the insertion piece only needs to simultaneously press the first button and the second button with one hand.

A connection arrangement for use with a wearable body harness includes a first connector having a first body component, a second body component, and an attachment element connected to each other by a rod having a longitudinal axis. The connection arrangement further includes a second connector removably connectable to the first connector. Each of the first body component, the second body component, and the attachment element are independently movable relative to each other about the longitudinal axis of the rod. The first connector and the second connector are removably connectable to each other via a locking and release mechanism between a first, locked configuration, where the first connector and the second connector are connected to each other, and a second, unlocked configuration, where the first connector and the second connector are disconnected from each other.

A buckle assembly includes a female buckle body that interchangeably mates with either one of a male buckle body or a retainer ring defining a leading bar. The female buckle body has a receptacle to receive an extension portion of the male buckle body slidable therein. A biased lever body is pivotally supported on the female buckle body for cooperating with a catch on the male buckle body between a blocking position retaining the extension portion in the receptacle and a released position allowing removal of the extension portion. The female buckle body also has a slot aligned with the receptacle to receive the leading bar of the retainer ring therein so that the lever body can also selectively retain the retainer ring mated with the female buckle body.

A buckle portion has a buckle body, at least one elastic locking leg connected to the buckle body, and a locking element comprising a plate having an actuation element. The locking element is connected to the elastic locking leg and is movable relative to the elastic locking leg by moving the actuation element between a locked position and an unlocked position. In the unlocked position, the elastic locking leg is movable so as to release the buckle portion from a corresponding buckle receptacle. In the locked position, the locking element prevents flexing of the elastic locking leg even under external pressure to keep the buckle portion from being released.

A tool belt (1) comprises a belt strap (2) and a belt buckle (3), wherein the belt buckle (3) comprises a male (5) and a female part (7). The male part (5) comprises a latch plate (27) and the female part (7) comprises a female interface (9) for receiving the latch plate (27). The latch plate (27) is attached to a first end (2a) of the belt strap (2) and the female part (7) is attached to a second end (2b) of the belt strap (2), and the female part (7) comprises a locking mechanism (15) adapted for connection and disconnection of the latch plate (27) to or from the female interface (9), and a length adjustment mechanism (17) adapted for adjustment of the length of the belt strap (2).
