The present disclosure describes an antenna mount. The antenna mount includes a clamp section including one or more clamping members, the one or more clamping members configured to engage a mounting structure, at least one adjustable plate pivotably coupled to at least one of the one or more clamping members, and an azimuth adjustment mechanism coupled to the at least one of the clamping members and the at least one adjustable plate. Through rotation of the azimuth adjustment mechanism, the at least one adjustable plate is configured to linearly move relative to the one or more clamping members to adjust an azimuth alignment of an antenna coupled thereto. Related antenna assemblies are also described herein.

A positioning device with tolerance compensation including: a screw; a primary tightening member, and a secondary nut. The screw includes a driving portion cooperating with a driving tool to rotatably drive the screw and is located in an axial end portion of the screw; primary and secondary external threads, the primary external thread being further from the driving portion than the secondary external thread, the directions of the secondary external thread and the primary external thread are opposing; and an abutment projecting between the primary and secondary external threads. The primary tightening member includes a primary internal thread adapted to cooperate with the primary external thread, the primary tightening member and the abutment secured to an intermediate component. The secondary nut includes a secondary internal thread cooperating with the secondary external thread and is configured to bear against the intermediate component to fasten a first component on a second component.

A coupling apparatus for joining two cleaning mops together for quickly cleaning a given floor area. The cleaning apparatus has two assemblies mounted to two cleaning mops respectively, and an elongated bar connects to the two assembles. Each assembly has a top plate and a bottom plate secured to the cleaning mop using a pair of fasteners. Each assembly has a pot magnet secured to one of the two fasteners.

A connecting piece includes a first connecting portion, a second connecting portion and an elastic portion. The elastic portion includes a first subsidiary elastic portion and a second subsidiary elastic portion. The first subsidiary elastic portion and the second subsidiary elastic portion are spaced apart from each other and respectively connected between the first connecting portion and the second connecting portion. The first subsidiary elastic portion has a plurality of first grooves. The first grooves are distributed on a side of the first subsidiary elastic portion away from the second subsidiary elastic portion. The second subsidiary elastic portion has a plurality of second grooves. The second grooves are distributed on a side of the second subsidiary elastic portion away from the first subsidiary elastic portion.

A kit includes an adjustable chock provided with a first component having screw threads and with a second component having screw threads cooperating with the screw threads of the first component and having a lower bearing surface, and with a bearing element provided with a lower bearing surface in contact with an upper bearing surface of the first component, and with an upper bearing surface. The kit further includes at least one friction ring adapted to be mounted against the lower bearing surface of the second component or against the upper bearing surface of the bearing element.

An irrigation system joint couples first and second adjacent pipe sections that are coaxial along a central axis when aligned. The joint comprises a first portion and a second portion. The first portion is for securing to the first pipe section and comprises an upwardly facing hemispherical surface. The second portion is for securing to the second pipe section and comprises a cavity that receives at least a portion of the hemispherical surface to form a contact line coincident with the central axis when the pipe sections are aligned.

A securing bracket and system are provided. The securing bracket is preferably used to secure two side panels of a housing together. The securing bracket is especially suitable for making housings of different shapes by allowing the side panels to be secured in a parallel or a perpendicular manner. The panels and securing brackets may be used to, for example, create a garden bed.
