A attachment system is formed by a primary device and a secondary device connected to the primary device in a pivoting manner. The primary device has a main body, two lateral sides and a bar for attaching the primary device to another object. Each of the lateral sides has a protrusion extending laterally outward from the lateral sides. The secondary device has two lateral sides, each equipped with an aperture that corresponds to one of the protrusions on the primary device, so that fitting the protrusions into the apertures pivotally connects the primary device to the secondary device, with the lateral sides of the secondary device being disposed outside of the lateral sides of the primary device. The secondary device can be pivoted between a folded position where the secondary device lies against the primary device, and an open position where the secondary device is raised up.

A buckle belt assembly includes a main body and a buckle belt. The buckle belt includes a first body and a second body sleeved on the first body. The second body includes a supporting portion, a second movable portion, and a band extending from a bottom of the supporting portion. One end of the second movable portion is connected to the supporting portion, and the other end of the second movable portion is movable relative to the supporting portion. The second movable portion includes a pair of side walls and a pair of fixing walls. The band is configured to hang hanging objects, the band is configured with a fixing hole, and the side walls are pressed to abut the fixing wall to the fixing hole or to detach the fixing wall from the fixing hole, thereby opening or closing the band.

The present disclosure relates to a plug for a buckle including the plug and a socket which are capable of being connected to and disconnected from each other and which are each attached to a predetermined member. The plug includes an attachment portion which is attached to the predetermined member; and a pair of leg portions which extend in the same direction from the attachment portion. An engagement portion is formed at the leg portion. The leg portion is bent at a plurality of bending points between the attachment portion and the engagement portion in an extending direction of the leg portion.

A pet buckle includes a buckle body and a snap-fit member that can be inserted and fastened together, and a buckle cavity is disposed in the buckle body, the clip component is provided with an insertion section matched with the fastening cavity and is used for the belt adjusting portion of the webbing adjustment is characterized in that: a stretched extending piece is disposed on a bottom surface of the buckle body fastening cavity, and the extending piece extends to the card when the button body and the engaging member are fastened to each other The strap adjustment portion of the connector presses the webbing of the strap adjustment portion.

The present invention discloses an integrated buckle of metal and plastics, comprising a female buckle and a male buckle. The male buckle comprises a male buckle body and left and right pins connected to the male buckle body. The male buckle body is made of metal, the left and right pins are connected to the male buckle body by rotating shafts to form a side-to-side rotational structure. A plastic flick piece is located between two pins, the plastic flick piece is fixed to the male buckle body. An elastic arm is located on both sides of plastic flick piece respectively, the two elastic arms hold two pins respectively. The present invention uses metal material to make male buckle body and pins, and the elasticity of pins is derived from the elastic arms on both sides of plastic flick piece.

A buckle structure contains a male buckle, two fastening arms, and a resilient sheet. The male buckle includes a first opening, a second opening opposite to the first opening, an external fence, and an accommodation cavity, wherein the external fence has two first orifices. Each of the two fastening arms includes a through hole, an engagement portion, a first abutting face, a second abutting face, and a column rotatably connected with the first orifice and the through hole so that the first abutting face and the second abutting face are located in the accommodation cavity of the male buckle, and the engagement portion of each fastening arm extends out of the first opening of the male buckle. The resilient sheet is formed in a U shape and includes a convex arc face and two contacting segments arranged on two ends of the resilient sheet respectively.

A buckle-type closing device (30), placed between two parts to be connected to one another, comprises a first component (31) and a second component (32) that are associable with one another in a releasable manner in which said first component (31) of said closing device (30) comprises a chamber (33) in which a magnet (34) is housed and a support element (35), and in which said second component (32) comprises a ferromagnetic locking element (40) that is adapted to interact, in operation, with said magnet (34), said locking element (40) being movable between a first released position and a second locking position in which it (40) is attracted by said magnet (34) against said support element (35), said locking element (40) consisting of a lever that is rotatable with respect to a pin (43), said lever having a folded end (46) forming a coupling element associable with said support element (35), said second component (32) comprising a mechanical element adapted to act on said locking element (40) to overcome the force of magnetic attraction of the magnet (34) and return the locking element (40) to the released position of said first component (31) with respect to said second component (32) of said closing device (30). Said mechanical element comprises a pair of release components (42) that are elastically opposite one another specularly with respect to the longitudinal centreline of said closing device (30), each release component comprising a respective inclined plane (44) adapted to release said locking element (40) wedging itself between said rotatable lever and a fixed part, and removing said rotatable lever with respect to said magnet (34) and thus releasing said locking element (40) from said support element (35).
