A cavity-type radio frequency filter is disclosed. the radio frequency filter having a cavity structure including an enclosure, a resonant element, a cover, a frequency tuning screw, and a resilient fixing member. The enclosure has a hollow inside and an open surface on one side to have a cavity. The resonant element is positioned in the hollow of the enclosure. The cover has a screw hole having a preset diameter at a position corresponding to the resonant element, and is configured to seal the open surface of the enclosure. The frequency tuning screw is configured to be screwed into the screw hole of the cover, and it has an upper end formed at least partially with a latching abutment that protrudes outwardly.

A fastening claw has an annular section with a radial inner side, from which at least two flexible, tongue-type elements project inwards and obliquely upwards towards an upper side of the fastening claw. The tongue-type elements have free ends which define a central, open region of the fastening claw, into which region a securing element can be introduced from the underside of the fastening claw and can be clamped between the free ends of the tongue-type elements.

There is provided a structure capable of ensuring a bearing surface pressure on an inner diameter side and an outer diameter side of a washer even if a thickness of the washer is suppressed. In a washer used at a fastening portion of a vehicle, a configuration in which a bearing surface is sectionalized into two faces, an inner abutting face and an outer abutting face, by an annular groove is adopted.

A fastener assembly is provided. The fastener assembly includes an insert having a radial circumference. An annulus extends from the insert and defines an annular end distal from the insert. The annulus further defines a radial cutout section along a length thereof for providing a flex point. The annulus is configured for being radially compressed by a blind hole of a working surface upon tightening of a nut. A nut is positioned adjacent the insert on an end distal the annulus, and a threaded bolt extends from the nut and through the annulus, wherein the bolt is configured to be accepted by the blind hole.

An optical assembly has an optical element mounted in the cavity of a barrel. A flexible ring is in contact with one of the surfaces of the optical element. The flexible ring has ring threads engaging barrel threads within the cavity. The flexible ring has a biased state in which the ring threads press against the barrel threads, and is resiliently deformable to a compressed state allowing screwing of the flexible ring within the cavity. In one variant, multiple subassemblies each having an optical element and a flexible ring are provided in the cavity of a barrel. The optical elements of subassemblies subsequent to the first one are supported by the flexible ring of the previous subassembly. The pressing of the ring threads against the barrel threads prevents a lateral shift of the flexible ring within the cavity, eliminating the decentering observed with conventional retaining rings.

An injection washer for an anchor system having a rod portion fixed to a surface, the injection washer including first and second opening portions arranged relative to each other along an axis parallel with the rod portion in use and which together define an opening through which the rod portion extends in use, the first opening portion having a smaller width than the second opening portion in a direction perpendicular to the rod portion and wherein a gap extends through a side of the injection washer into each of the first and second opening portions.

A truck cover system with a rail defining a cover slot that couples to a cover that extends over a bed of a truck. A clamp system couples the rail to a truck wall. The clamp system includes a first clamp frame that couples to the truck wall, and the first clamp frame includes first and second ends with respective first and second sets of teeth. The first set of teeth engages rail teeth on the rail, and a second clamp frame couples to the rail and to the first clamp frame to secure the rail to the truck. The second clamp frame includes third and fourth ends with respective third and fourth sets of teeth. The third set of teeth couples to the truck wall and the fourth set of teeth couples to the second set of teeth of the first clamp frame.

A clip assembly is provided including a clip having a support leg joined with a control arm, an actuator, and a displacement control element operable to engage the control arm and hold the support leg in a retracted mode. The actuator is movable relative to the clip and/or a carrier associated with the clip to disengage the displacement control element from the control arm and thereby deploy the associated support leg from the body to secure the clip to the panel. The clip can include a retention leg to retain the clip relative to the panel upon installation of the clip relative to the panel. A related method of use is provided.

A garment rack comprising a bottom frame having a Z-shape; a first bottom vertical tube having a first end and a second end, the first end detachably connected to the bottom frame and the second end detachably connected to a first or female top frame; a second bottom vertical tube having a first end and a second end, the first end detachably connected to the bottom frame and the second end detachably connected to a second or male top frame; a first or female top frame detachably connected the first bottom vertical tube; and a second or male top frame detachably connected to the second bottom vertical tube; the male top frame detachably connected to the female top frame.
