A connection assembly for prefabricated components provided herein includes two C-shaped groove members and an H-shaped connection member. The C-shaped groove members are each provided with a component connecting part for fixedly connecting with a component, the H-shaped connection member includes a middle web and two side flanges, notches of the C-shaped groove members are in clearance fit with the web, and the side flanges are in stop fit with inverted edges of the C-shaped groove members when the H-shaped connection member is inserted between the C-shaped groove members. The C-shaped groove members and/or the H-shaped connection member are each provided with wedge members, and the wedge members have wedge surfaces for guiding the two C-shaped groove members to be fastened oppositely. The integrated H-shaped connection member replaces multiple bolts to meet the requirements of high-strength connection, which simplifies the operation and improves the construction efficiency.

The present disclosure provides systems and methods for a modular fastener assembly for use with multiple panel members. In some embodiments, the fastener assembly can include one or more fasteners (i.e., connectors, clips, etc.). Each of the fasteners can include a channel configured to receive an edge of a panel member, a coupling protrusion extending from an outer surface of the fastener, and an opening formed on another external surface of the fastener configured to be complementarily shaped to the coupling protrusion such that a coupling protrusion on another fastener can be received in the opening to secure two fasteners of the fastener assembly together.

A lock and pin for the structural and fluid tight repair of cracks not amenable to high temperature repairs or synthetic material patches. Fluid tight pins and. locks seal the crack while one or more locks prevent the crack from growing. These repairs need to endure the remaining life cycle of the machinery part while withstanding all the strain, pressure, heat and expansion and contraction of the part before the crack(s) were formed. Often these cracks evolved due to engineering design flaws that will require even greater strength from these areas than when new.

A wrench rack includes a base portion having a first side and a second side, and a first rail and a second rail. Each of the first rail and second rail includes a plurality of wrench slots formed at a predetermined angle. The first rail and second rail are releasably coupled with the first side and second side of the base portion, respectively, in a first configuration and the first rail and second rail are releasably coupled to the second side and first side of the base portion, respectively, in a second configuration, such that an orientation of the predetermined angle of the wrench slots of the first configuration is reversed in the second configuration.

The present invention pertains to a hinged device for use in securely storing or organizing a variety of different devices in a variety of different locations, such as, for example, a plurality of fishing rods. The present invention pertains to a storage clasp apparatus and modular track assembly, having a plurality of storage clasps comprising a hinged member and an internal bore for easily receiving and removing said fishing rods. More particularly, the present invention pertains to a storage clasp apparatus and modular track assembly, having at least one slide track member for use in easily and efficiently mounting a plurality of said storage clasps, and thus, maintaining and storing said fishing rods in an organized manner.

An external screw member includes a parallel screw portion and a tapered screw portion provided on a side further toward a tip end than the parallel screw portion, and a plurality of sets of step portion and a transition screw thread portion are provided on at least one of the parallel screw portion and the tapered screw portion, the step portion having a reduced thread height in a radial direction and the transition screw thread portion gradually increasing in diameter from the step portion in an anti-driving rotation direction so as to reach a thread height of a normal screw thread portion. A top portion of the transition screw thread portion is positioned at an offset toward a pressure side relative to a position of a regular screw pitch in a minimum diameter portion of the step portion, and transitions to the regular screw pitch in the anti-driving rotation direction.

The present invention provides a dovetail structure of a connector that can be disposed on a first joint surface and a second joint surface of a casing. The dovetail structure includes a pin module and a slot module. An interference structure formed by the pin module and the slot module enables the two connectors with a dovetail structure to be assembled easily to achieve a stable combination.

A bracket assembly for coupling a component to a vehicle including a bracket body including a C-ring retainer that is adapted to translatably engage and retain a T-shaped guide rail coupled to one of a crossmember and floor structure of the vehicle, wherein the bracket body defines a hole or includes an attachment structure adapted to receive and retain the component. The bracket body further includes one or more flanges adapted to secure the bracket body to the crossmember or floor structure of the vehicle via bolting and/or welding. Optionally, the bracket body includes: a front attachment arm; a rear attachment arm; one or more intervening structural reinforcement members; a bottom portion coupled to the attachment arms; and a cap structure coupled to the attachment arms opposite the bottom portion; wherein the bottom portion includes the C-ring retainer and the cap structure defines the hole or includes the attachment structure.

A retaining assembly to attach one or more mobile devices to a mobile object. The retaining assembly may include a mounting plate that attaches to the mobile object by way of a mounting bracket or scorecard clip-on. The mounting bracket provides dovetails for selecting engaging the mounting plate in different orientations. The mounting plate facilitates various magnetized components to removably attach to the mobile device. If the mobile device has a third-party extensible grip, a retaining ring may be employed to attach the mobile device or the extensible grip modified to one of the various magnetized components.

A wrench rack includes a base portion having a first side and a second side, and a first rail and a second rail. Each of the first rail and second rail includes a plurality of wrench slots formed at a predetermined angle. The first rail and second rail are releasably coupled with the first side and second side of the base portion, respectively, in a first configuration and the first rail and second rail are releasably coupled to the second side and first side of the base portion, respectively, in a second configuration, such that an orientation of the predetermined angle of the wrench slots of the first configuration is reversed in the second configuration.
