The present disclosure provides a detachable buckle, including a belt head, a tail clamp, a fixing base, buckle buttons. One end of the fixing base is a hollow slot, the one end of the fixing base is connected with the tail clamp, and at least one socket is disposed on the one end of the fixing base. An opening is disposed on an edge of the hollow slot. Sliding grooves are disposed on both ends of the tail clamp, and the one end of the tail clamp is near the fixing base. Insert blocks sliding along the sliding grooves are disposed inside the sliding grooves. The insert blocks are connected with the buckle buttons, the buckle buttons drive the insert blocks to enter the hollow slot of the fixing base by pushing the tail clamp, and the buckle buttons are fixed with the sockets.

A buckle operable with a securement strap. In a most preferred form, the buckle is a belt buckle for a belt including a belt strap having a free end, a connection end and an inner surface having one or more belt strap abutment portions. The buckle includes a body having a first end, a second end and a surface disposed between the first and second ends. The body further includes at least one buckle abutment portion extending outwardly or inwardly from the surface. The first end of the body is configured to be connected to a connection end of a belt strap. The at least one buckle abutment portion is configured to engage (i.e., to contact directly or be positioned to act with) at least one belt strap abutment portion. A release can be movably connected to the body. The moveable release (if used) can slide, pivot or otherwise move relative to the at least one buckle abutment portion.

A mechanical-magnetic locking device includes a first connecting component, a second connecting component and a magnet-armature structure. The first connecting component is provided with a locking element with a gap. The second connecting component is provided with a locking member matched with the locking element with the gap. A magnet is provided in one connecting component and an armature is provided in the other connecting component. The locking element with the gap is coupled with the magnet and the armature is coupled with the locking member. When opening the locking device, the magnet and the armature are relatively moved to each other, and the magnetic attracting area is substantially unchanged or increased, allowing the locking element with the gap and the locking member to move from the engaged position to the non-engaged position.

A buckle with a string adjustment portion includes a plug and a socket. The plug includes: a tightening string member attachment portion configured to slidably lock a string member and adjust a length of the string member; and leg portions which are inserted into and engaged with the socket. The socket includes a fitting portion including an insertion opening. An insertion hole through which the string member is inserted is formed to penetrate the tightening string member attachment portion, and a portion connecting the leg portions side of the insertion hole serves as a second bar. The second bar is located on an insertion direction side of the leg portions with respect to a position where an end portion of the plug and the insertion opening of the socket are abutted against each other, in a state where the leg portions are engaged with the socket.

A belt has a strap. A detachable buckle is attached to a first end of the strap. The detachable buckle has a base. A cutout is formed on a front surface of the base. A removable is faceplate inserted and held within the cutout. A ratchet mechanism secures a second end of the strap within the detachable buckle.

A seatbelt indicator clip is shown and described. The seatbelt indicator clip includes a planar body. The planar body has a protrusion extending from one side. The protrusion is a seatbelt male connector. The seatbelt male connector is sized to be received by a seatbelt female connector. The planar body has an attachment device secured thereto. The attachment device will allow the seatbelt indicator clip to be secured to a device when in storage.

The invention relates to a belt buckle with long usage rate, which comprises a buckle body and a mounting member, wherein the left side surface and the right side surface of a mounting rod body are both cutting planes, the left side surface of the mounting member is provided with a through concave cavity, the left end of an upper sheet body and the left end of a lower sheet body are both integrally formed with extension sheets extending downwards, a clamping interval is arranged between the free ends of the two extension sheets, the mounting rod body is clamped into the through concave cavity through the clamping interval and is rotatably arranged in the through concave cavity. Compared with the prior art, the buckle body is detachably connected with the mounting member, so that the free combination of different buckle bodies and different mounting members is realized.

The invention relates to a universal double-sided belt buckle, which comprises a buckle body, a mounting member and a buckle pin, the left end of an upper sheet body and the left end of a lower sheet body are both integrally formed with extension sheets extending downwards, a clamping interval is arranged between the free ends of the two extension sheets, the left side of the mounting member, at the position corresponding to the first end of the buckle pin, is concavely provided with an accommodating recess which is communicated with the through concave cavity and used to accommodate the part of the buckle pin positioned at the mounting member and make it be able to rotate. Compared with the prior art, the buckle body is detachably connected with the mounting member, so that the utilization rate of the buckle body is improved.

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 according to the present invention has a fixed loop end and an adjustable loop end. The adjustable loop end includes two belt strap openings separated by a central bar with a pair of guiding tabs on opposite ends of the central bar that extend outward from the central bar. Other embodiments of the buckle include a protrusion extending from a lower surface of the fixed loop end. In other embodiments, the adjustable loop end and central bar are configured to have male and female joint portions to aid in preventing unnecessary rotation of the buckle. Optionally the adjustable loop end may include a scalloped lip along its leading edge of the lower surface.
