The present invention discloses a belt buckle assembly and a weightlifting belt, and belongs to the technical field of belts. The belt buckle assembly according to the present invention comprises a belt buckle base plate, a pin shaft member, a ratchet wheel and a handle ratchet which fit each other, and a swing handle housing, wherein the swing handle housing is rotatably mounted on the belt buckle base plate through the pin shaft member; the handle ratchet is rotatably supported and mounted on the swing handle housing; the ratchet wheel is provided with a center hole and is sleeved on the pin shaft member through the center hole; and the ratchet wheel is provided with an unlocking slot. The belt buckle assembly further comprises a ratchet wheel unlocking mechanism, wherein the ratchet wheel unlocking mechanism comprises an unlocking assembly, which can move axially or radially along the pin shaft member.

A lace tensioning device includes a housing component having an interior region, a first aperture, and a second aperture, and a spool component that is rotatably positionable within the interior region of the housing component. The spool component has a central cylindrical member and a lumen that extends through the central cylindrical portion. The spool component is rotatable within the interior region of the housing component to align one end of the lumen with the first aperture and to align an opposite end of the lumen with the second aperture to enable a lace to be inserted through the first aperture, the lumen, and the second aperture so that opposing ends of the lace are positioned exterior to the housing component. A knot may then be tied in the lace and the lace retracted to couple the lace with the housing component and spool component.

A buckle according to the present invention has two opposing ends that are removably attached to each other using a locking system. On one end of the buckle, the locking system includes two opposing locking pins coupled to a spring that is fully enclosed and protected from external elements. On the other end, corresponding rivets or pin casings with plungers are operable to receive the locking pins and lock the two ends together or push the pins out of the casings to release the buckle. The buckle may also include a plug that is removably attached to the adjustable loop end and allows the central bar of the adjustable loop end to be removed without deforming the central bar. Alternatively, each end of the buckle may include self-aligning tabs that guide the ends of the buckle for fastening and aid in the stability of the buckle.

The present disclosure relates to an anti-jamming ratchet-type tensioning device, comprising a base, a winding and unwinding mechanism with a ratchet wheel, and an operating mechanism. The operating mechanism controls locking or unlocking via a lever element, with an elastic check claw provided at the executing end of the lever element to prevent reverse rotation of the ratchet wheel. The key feature lies in the design of the lever element's pivot point as a movable structure. When the ratchet wheel rotates clockwise and pushes the check claw, the lever element can move upward with the thrust to avoid obstruction, reducing frictional resistance, effectively preventing jamming, and ensuring smooth and effortless webbing extraction.

Various fastening systems for an object (e.g., a wearable such as footwear) are disclosed, including a buckle assembly and a prong for adjusting tension. The buckle assembly may a pawl. The prong includes an array of teeth to engage with the pawl formed on the base. The fastening system is configurable between an engaged condition and a released condition based on the positioning of the slider relative to the base.
