A composite structure includes: a cover plate having a countersunk hole and a plate side fitting hole; a bearing plate having a screw hole and a screw side fitting hole located opposite from the plate side fitting hole through the screw hole; and a plate screw component including a screw part engaged with the screw hole, and a plate side fitting part and a screw side fitting part respectively fitted with the plate side fitting hole and the screw side fitting hole to be in alignment with each other. A difference a in diameter between the plate side fitting hole and the plate side fitting part, a difference b in diameter between the screw side fitting hole and the screw side fitting part, and an effective difference c in diameter between the screw hole and the screw part satisfy a dimensional relation of a<c and b<c.

The present invention relates to side tensioning assemblies for retaining screen media to the side plates of a vibrating-type screening machine. The side tensioning assembly includes a tensioning rail and at least one angle box mountable to a side plate. At least one bolt assembly provided for fastening the tensioning rail to the side plate and to angle box. Bolt assembly is provided with is a shoulder bolt that is secured to a terminal end of the bolt. The angle box includes an aperture sized to allow the bolt assembly passage therethrough, and a movable plate with a cutout. The cutout is sized larger than the bolt but smaller than a nut. The movable plate has a bolt-securing position and a bolt-releasing position to allow access to the aperture in the angle box such that the bolt assembly can be detached from the angle box without being disassembled.

The present invention relates to side tensioning assemblies for retaining screen media to the side plates of a vibrating-type screening machine. The side tensioning assembly includes a support structure for supporting the screen media and tensioning rail mountable to at least one side plate. At least one bolt assembly provided for fastening the tensioning rail to at least one of the side plates. Each bolt assembly including a bolt connectable to the tensioning rail, at least one of side plates and at least one bolt engaging structure on a surface of the side plate. Each bolt engaging structure includes a cutout. The cutout is sized larger than the bolt but smaller than a nut. The movable plate has a bolt-securing position and a bolt-releasing position.

An apparatus includes a mounting component with an opposed exterior surface configured to adapt to a curvature of a helmet via an attachment portion and angularly defined guide rails and friction slots. A cradle includes an exterior portion configured to receive an accessory and friction receiving coupler to integrate said cradle to said mounting component whereby cradle will travel non-linearly along the angularly defined guiderails of the mounting component. Friction inducing elements increase friction between the mounting component and the cradle where the friction is induced by mechanical elements, where the mechanical elements are adjustable by hand power.

A fastening structure and a fastening method thereof include a body part and a fastening part. The body part has an entering part and can be arranged at an object, and the fastening part is arranged at the body part; and a fastened object laterally enters the entering part, so as to fasten the fastening part into a fastened part of the fastened object, so that the fastened object is limited to the body part, or the fastened object is simultaneously horizontally and vertically limited by the entering part and the fastening part. Thus, the cooperation of the entering part of the body part and the fastening part can be used to complete a quick combination of at least two objects, so as to achieve the effect of repeated and quick combination and separation.

A system and method are disclosed for quickly and easily assembling PV modules into a PV array in a sturdy and durable manner. In examples of the present technology, the system includes various couplings having a first engaging portion adapted to engage a first PV module and a second engaging portion adapted to engage a second PV module. At least one of the engaging portions allows variable positioning of the engaged PV module along the engaging portion.

An adjustable bracket assembly for securing an edge of a panel relative to a surface. The adjustable bracket assembly includes a mounting member and a bracket member. The mounting member has a body configured for mounting on the surface and defining at least two fastening screw receiving holes. The bracket member includes an extension arm extending perpendicularly to a mounting arm. The extension arm includes a panel clamp and the mounting arm includes a mounting plate extending therefrom. The mounting plate defines at least two fastening screw holes and at least two adjustment screw holes therethrough. A fastening screw extends through each fastening screw hole and is received in a respective fastening screw receiving hole. An adjustment screw is positioned in each adjustment screw hole and is threadably adjustable to contact the mounting member body and adjust the angular relationship between the bracket member and the mounting member.

A locating structure includes a fixture and a locating member. The fixture includes a body and a fastener, wherein the fastener is movably provided at the body. The body is configured to assemble with a first object, and the fastener is configured to fasteningly connect to a second object or be removed from the second object. The locating member is movably assembled with the body, and the locating member may press against or drive the fastener to locate the fastener at a located position, or the locating member may move or drive the fastener to locate the fastener at a locating-released position. Thus, the locating member may be moved to locate the fastener at the located position or at the locating-released position, so as to complete coupling or separation of at least two objects, achieving the effect of repeated quick coupling and separation.
