An apparatus for connecting one or more guy wires to a down rod, the connector having first and second separable portions which form an aperture for receiving the down rod. At least one of the first or second portions includes at least one passage adapted for releasably receiving a portion of the guy wire. The guy wire may include an anchor, and the passage for receiving the guy wire may be adapted for capturing the anchor so as to preclude movement of the guy wire in a radial direction.

A ceiling fan assembly having a motor with a rotor and a stator, at least one blade operably coupled to the stator, a motor shaft extending from the stator and having an internal wire passage and a wire opening in a side of the motor shaft, with the wire opening providing access to the internal wire passage, a control mounting plate having a motor shaft opening through which the motor shaft extends and an electronic control unit carried by a side of the control mounting plate.

A ceiling fan assembly or similar air-moving device can include a motor for rotating one or more blades to drive a volume of air about a space. The ceiling fan assembly can further include a hanger ball with an indexing pin. The ball hanger can be received by a mounting bracket so that, via an alignment guide, the indexing pin of the hanger ball aligns with an indexing groove on the mounting bracket.

The present utility model discloses a modular magnetic-type fan convenient for installation, which comprises a housing, a magnetic-type structure and an electrical-connection structure; the housing is surrounded by a plurality of side frames; the magnetic-type structure comprises a first magnetic part and a second magnetic part arranged on both side frames; the electrical-connection structure comprises a first electrical-connection part and a second electrical-connection part arranged on two side frames; the users can splice fans in accordance with their actual needs make the fan combinations more convenient and avoid messy electrical connection.

An assembly includes a first bracket and a second bracket. The first bracket includes a first member that includes a plurality of fingers and a first channel between the plurality of fingers. The first channel includes a plurality of teeth. A first flange extends from the first member and includes a first engagement surface. The second bracket includes a second member and a third member spaced from the second member. A second channel is formed between the second member and the third member. A second flange extends from the second member on an opposite side of the second member from the third member. The second flange includes a second engagement surface. In an installed configuration, the first bracket is secured to the second bracket; the first engagement surface faces the second engagement surface; and the plurality of fingers are inserted into the second channel.

A ceiling fan mount assembly having a downrod assembly with a downrod and a motor assembly comprising motor and including a motor shaft. The ceiling fan mount assembly further includes a downrod plate coupled to the downrod and a shaft coupler coupled to the motor shaft and coupled to the downrod plate, whereby coupling the downrod plate to the shaft coupler suspends the motor from the downrod.

An alignment tool for aligning a plurality of diffuser pipes of a centrifugal compressor relative to a casing of an aircraft engine. The alignment tool includes a body defining a center axis and having at least one tool datum configured for abutting against the casing. A plurality of alignment members are fixed to the body and extend radially from the body relative to the center axis. Each alignment member of the plurality of alignment members has a respective fixed position relative to the at least one tool datum. The plurality of alignment members are configured to abut the plurality of diffuser pipes.

The present disclosure provides descriptions of electrical box assemblies for supporting heavy fixtures, such as ceiling fans, and facilitating electrical connections to the fixtures. The electrical box assembly includes an electrical box that allows a connection between the box and electrical conduits and a connection, e.g., a weatherproof connection, with a housing of the fixture. The box has an open front face to house electrical connections between the fixture and wires supplying electrical power to the box via the conduits. The box has a bottom wall and an open front face. A reinforcement member fits within the electrical box and includes a panel shaped to conform to at least a portion of the bottom wall and one or more standoffs extending toward the open front face of the box. When the reinforcement member is positioned within the box, mounting holes in the bottom wall of the box and reinforcement member are aligned to allow the box to be attached to a building structure.

A noise reduction structure for a ventilation treatment device and the ventilation treatment device are provided. The noise reduction structure comprises a first micropore plate; the first micropore plate has a first plate surface and a second plate surface which are opposite to each other, the first plate surface is used for forming a first chamber; the second plate surface is used for forming an air passage such that air in the air passage flows along the second plate surface; the first micropore plate has a plurality of first micro-vias through which the first chamber communicates with the air passage. The noise reduction structure is wide in noise reduction frequency band, may effectively reduce aerodynamic noise in the air passage, and improves the satisfaction degree of a patient using the ventilation treatment device.
