The present invention belongs to the technical field of electric push rods, and specifically discloses a sliding limit type nut structure, a telescopic rod and an electric push rod. The sliding limit type nut structure includes a sliding contact assembly, where an inner wall of the sliding contact assembly is provided with internal threads, both ends of the sliding contact assembly are provided with external threads and a sliding sleeve, respectively, and an outer wall of the sliding sleeve is provided with chutes. According to the present invention, the internal threads of the sliding contact assembly and the chutes on the sliding sleeve are used to convert a helical motion into stable linear sliding, which makes the motion process more stable.

An adjustable fastener system generally includes an anchor component, a drive component, and a finish head component. The finish head component is threaded onto the anchor component to form the completed fastener that may be adjusted to different heights. The drive component is used to drive the anchor component into position prior to adjusting the finish head component. In some embodiments, the drive component may be used before the finish head component is installed, and in other embodiments, the drive component may be used with the finish head component installed. The adjustable fastener system saves time and effort at a construction site, eliminates the amount of prep work, and eliminates the need to have multiple different fasteners on site. The adjustable fastener system may be used for installing insulation panels over concrete in a roofing system as well as other applications.

A fluid end having its fluid flow bores sealed without threading a retaining nut into the walls of each bore. The fluid ends may be assembled using a plurality of different kits, each kit comprising a fluid end body, a component, a retainer element, and a fastening system. The retainer element holds the component within each of the bores formed in the fluid end body and the fastening system secures the retainer element to the body. The fastening system comprises a plurality of externally threaded studs, washers and nuts in some embodiments. In other embodiments, the fastening system comprises a plurality of screws.

A substrate usable with a double-side adhesive strip to suspend the substrate to a wall surface. The substrate can have one or more access holes located within an outer perimeter of the substrate. Each access hole has an inner perimeter inwardly of the outer perimeter that is sized and shaped to allow a tab of the double-sided adhesive strip to be extracted through the inner perimeter, after the substrate is suspended on the wall surface. Various articles can attach to the suspended substrate, such as through magnetic attachment, a hook, or a shelf.

A threaded fastener assembly for use with a nut includes a shaft head and a separate shaft. The shaft head includes a head, and an internally-threaded portion. The shaft has a first externally-threaded portion for cooperation with the internally-threaded portion of the shaft head to selectively secure the shaft to the shaft head, a second externally-threaded portion for cooperation with the nut, and an integrated nut or wrenching portion for tightening the shaft to the shaft head.

A mounting system having a dual plunger arrangement wherein the side of each plunger has a pull down cam to provide a desired pull down action in relation to at least two studs, the cams moving relative to one another and axially aligning relative to one another relative to the two axially spaced pull down studs to allow the plungers to provide a maximum hold down force for the two pull down studs, balance the hold down forces thereby maximizing performance and reducing unlocking forces.

A device for resisting rotation of a tap fitted to a work surface comprises a body; an engagement formation for engaging with a part of the tap; and an attachment means for irrotatably attaching the device to the tap. The device further comprises fastening means for irrotatably fastening the device to a work surface.

An assembly for a turbomachine turbine includes at least one ring sector made of CMC material and a support casing including an upstream flange and a downstream flange between which each ring sector is disposed, each ring sector including a base that has a radially external face from which radially extend two lugs, the lugs of each ring sector being retained between the two flanges of the support casing by axial pins each engaged in one of the flanges of the ring support casing and in the lug of the ring sector facing said flange, the assembly further including, for each ring sector, at least one radial retaining pin screwed into the support casing and coming to radially bear against a lug of the at least one ring sector to retain it in position, and anti-rotation system for rotationally locking the radial retaining pin.

A bracket for hanging an item on a wall is disclosed. The bracket has one or more bracket apertures which are used to mount the bracket to the hanging item. The hanging item could be an item like a picture or a shelf. The bracket has a mounting aperture which is used to mount the hanging item on a nail or a screw. Adjacent to the mounting aperture is a pinhole having a set screw. To use the bracket the user unthreads the set screw from the pinhole opening. The user places the hanging item in its desired location on the wall and pushes the item against the wall so that the set screw marks a spot on the wall where the user should place a nail or a screw for hanging the item.
