[0050] Example 1

[0051] refer to Figures 1-9 , this embodiment provides a mounting structure 100 for ceiling-mounted installation of electrical equipment. The mounting structure includes a plug assembly 1 and a socket assembly 2, and the plug assembly 1 is detachably connected to the socket assembly 2. The socket assembly 2 is fixedly connected to a mounting base, such as a ceiling, a suspended ceiling or a wall, and the plug assembly 1 is fixedly connected to the electrical appliance body. The installation of the two is achieved by inserting and rotating the plug assembly 1 into the socket assembly; when disassembly is required, lift and rotate the first shell in opposite directions, and then pull it out to complete the disassembly. In other embodiments, the plug assembly can also be fixedly connected to the mounting base, and the socket assembly can be fixedly connected to the electrical appliance body. In this embodiment, the plug assembly fixedly connected to the electrical appliance body and the socket assembly fixedly connected to the mounting base are used as examples for explanation.

[0052] The plug assembly 1 includes a first housing 11 and a plug 12. The first housing 11 is provided with a first connecting arm 111. The plug 12 and the first connecting arm 111 are arranged inside the first housing 11. The first connecting arm 111 is located outside the plug 12 and is fixedly connected to the plug 12.

[0053] The socket assembly 2 includes a second shell 21 and a socket 22 . The socket 22 is disposed inside the second shell 21 . A slot 211 is disposed on the second shell 21 .

[0054] The plug assembly 1 is connected to the socket assembly 2 by plugging. The plug 12 is coupled to the socket 22 to achieve electrical connection, and the first connecting arm 111 is screwed into and snap-connected to the slot 211.

[0055] Specifically, the plug assembly and the socket assembly are axially aligned, the plug 12 is then inserted into the socket 22, and the first housing 11 is rotated so that the first connecting arm 111 is screwed into and engaged with the slot 211 of the second housing 21. Since the plug 12 and the socket 22 have already been connected to the appliance body and the external power source, respectively, during the assembly process of the mounting structure 100, the connection between the plug 12 and the socket 22 is a coupled power connection. No additional wiring is required during the connection process, which saves steps and makes installation convenient and quick. In addition, the first connecting arm 111 is engaged in the slot 211, and the first housing needs to be lifted and rotated to separate it from the second housing. Therefore, the connection of the mounting structure is stable and not easy to loosen.

[0056] The first shell 11 includes a base plate 112 and a first side plate 113. The first side plate 113 is arranged on the base plate 112, and the first side plate 113 and the base plate 112 surround and form a first chamber 110. In some embodiments, the first side plate 113 extends from the outer periphery of the base plate 112 along the installation direction, and the first side plate 113 and the base plate 112 are an integral or split structure. When the first side plate 113 and the base plate 112 are split structures, they can be fixed together by welding or bonding. In some embodiments, the first side plate 113 and the base plate 112 are an integrally molded structure. In this embodiment, the first side plate 113 and the base plate 112 are an integrally stamped structure. In addition, the first side plate 113 is surrounded by a columnar or cylindrical structure, the base plate 112 is an annular structure, and the diameter of the base plate 112 is larger than the diameter of the columnar structure formed by the first side plate 113, that is, the first shell 111 is roughly a cap-shaped structure.

[0057] First connecting arms 111 are cut from the first side panel 113 and bent toward the first chamber 110. These arms are evenly distributed around the outside of the plug 12. In this embodiment, there are three first connecting arms 111; in other embodiments, there may be two, forming a beam-like structure; or four, five, or other first connecting arms 111. The plug 2 is located within the first chamber 110 and is fixedly connected to the evenly distributed first connecting arms 111.

[0058] The second housing 21 includes a second side panel 212 and a second connecting arm 213. The second side panel 212 surrounds and forms a second chamber 210. The second connecting arm 213 is disposed within the second chamber 210 and is located outside the socket 22. Specifically, the second side panel 212 surrounds and forms a columnar or cylindrical structure. The second connecting arm 213 is cut from the second side panel 212 and then bent toward the second chamber 210. The socket 22 is located within the second chamber 210. Like the first connecting arm 111, the second connecting arm 213 in this embodiment is also provided in three pieces. The three second connecting arms 213 are evenly distributed outside the socket 22 and are fixedly connected to the socket 22.

[0059] The first chamber 110 has an opening 1101, through which the second housing 21 enters the first chamber 110. The second chamber 210 is connected to the first chamber 110. After the plug assembly 1 and the receptacle assembly 2 are plugged together, the second side plate 212 is snugly connected to the inner side of the first side plate 113. This snug connection prevents displacement due to vibration.

[0060] At the same time, the top end 2121 of the second side plate 212 is flush with or protrudes from the opening 1101 of the first chamber 110. Figure 2 As shown, in the mounting structure 100 of this embodiment, the top end 2121 of the second side plate 212 protrudes from the opening 1101 of the first chamber 110. In this way, the end of the first side plate 113 does not contact the mounting base, thereby preventing scratches from being caused by the ceiling, suspended ceiling, or wall when the first housing rotates.

[0061] The second shell 21 is also provided with a mounting plate 214, which is bent from the top 2121 of the second side plate 212 toward the second chamber 210. A mounting hole 2141 is opened on the mounting plate 214, and locking parts such as expansion screws are passed through the mounting hole 2141 to fix the second shell 21 on the mounting base.

[0062] Combined with reference Figure 4 and Figure 5 The groove body 211 includes a guide groove 2111, a positioning groove 2112, and a limiting groove 2113. The guide groove 2111 extends from the bottom end 2122 of the second side plate 212 toward the top end 2121. The positioning groove 2112 and the limiting groove 2113 extend along the circumference of the second side plate 212. The positioning groove 2112 is located between the guide groove 2111 and the limiting groove 2113, and the positioning groove 2112 is connected to the guide groove 2111 and the limiting groove 2113 respectively.

[0063] It should be noted that, in this embodiment, Figure 4As shown, during the process of plugging and installing the first shell 11 into the second shell 21, the first connecting arm 111 first approaches upward along the installation direction and enters the guide groove 2111, and then rotates circumferentially and enters the positioning groove 2112 and the limiting groove 2113 in turn, that is, the first connecting arm 111 is screwed into the positioning groove 2112 and fixedly connected to the limiting groove 2113.

[0064] In the slot body 211, the height of the positioning slot is H1, and the height of the limiting slot is H2. Since the first connecting arm 111 needs to fall back downward after passing through the positioning slot 2112 and entering the limiting slot 2113, the height of the limiting slot is greater than the height of the positioning slot, that is, H2>H1.

[0065] Combined with reference Figure 5 and Figure 6 The width of the first connecting arm 111 is W1, the width of the guide groove 2111 is W2, and the width of the limiting groove 2113 is W3, which has the relationship: W1≤W3<W2.

[0066] The width W3 of the limiting groove 2113 is equal to or slightly larger than the width W1 of the first connecting arm 111. This allows the limiting groove 2113 to circumferentially restrict the movement of the first connecting arm 111. The width W2 of the guide groove 2111 is larger than the width W1 of the first connecting arm 111, allowing the first connecting arm 111 to enter the guide groove 2111 smoothly. The second side plate 212 also has an arc-shaped corner structure at the bottom end of the guide groove 2111 to further facilitate the entry of the first connecting arm 111 into the guide groove 2111.

[0067] Back to Figure 1 The mounting structure 100 also includes a retaining member 3, such as a countersunk screw. In the plug assembly 1, the first side plate 113 defines a first retaining hole 1131, which is a through-hole structure. In the receptacle assembly 2, the second side plate 212 defines a second retaining hole 2123, which is a blind hole structure.

[0068] When the first connecting arm 111 is screwed into and installed in the groove body 211, the limiting member 3 radially passes through the first limiting hole 1131 and is fixedly connected to the second limiting hole 2123, thereby preventing the first shell 11 from being displaced in the circumferential direction relative to the second shell 21.

[0069] The installation structure provided in this embodiment has a detachable connection between the plug assembly and the socket assembly. The plug assembly is screwed into and snapped into the groove of the second shell through the first connecting arm inside the first shell, so that the first shell and the second shell are stably connected, avoiding the situation where the electrical body is vibrated and causes displacement during operation; in addition, the plug is directly coupled to the socket to complete the power connection, eliminating the wiring process; the entire installation process is convenient and safe, and can be completed by one person.

[0070] Example 2

[0071] Figure 7 and Figure 8 They are exploded views of the plug and socket of this embodiment, Figures 1-6 Based on reference Figure 7 and Figure 8 , this embodiment further illustrates the plug and socket of the installation structure.

[0072] like Figure 7 As shown, the plug 12 includes a first base 121, a first base cover 122, and a first power connector 123. The first power connector 123 comprises two copper rings of different sizes and a copper post. The first base 121 has an annular plug groove 1210, into which the first power connector is mounted. Furthermore, the first power connector 123 protrudes from one side of the first base 121, while the first base cover 122 is fixedly connected to the other side of the first base 121. The first base cover 122 is supported by the first power connector 123.

[0073] like Figure 8 As shown, the socket 22 includes a second base 221, a second base cover 222, and a second power connection assembly 223. The second power connection assembly 223 comprises three copper pillars. An annular power connection groove 2210 is defined on one side of the second base 221, and the second power connection assembly 223 is positioned within the groove. The second base cover 222 is fixedly connected to the other side of the second base 221 and supported by the second power connection assembly 223.

[0074] The first power connection assembly 123 is electrically connected to the appliance body, and the second power connection assembly 223 is electrically connected to the external power supply. When the plug 12 is coupled to the socket 22, the first power connection assembly 123 is electrically connected to the second power connection assembly 223, thereby realizing a wiring-free electrical connection method.

[0075] Example 3

[0076] exist Figures 1-8 Based on reference Figure 9 and Figure 10 This embodiment provides an electrical device, including an electrical device body 200, a mounting base 300, and the mounting structure 100 of embodiment 1 or embodiment 2. The electrical device can be a fan light, a ceiling light, or a ceiling audio system (speaker). This embodiment uses a fan light as an example for description.

[0077] In this embodiment, the appliance body 200 is a fan light, and the plug assembly 1 is fixedly connected to the appliance body 200 via a mounting base 300. Specifically, the mounting base 300 defines a rectangular slot 301 with a wire guide for receiving the plug mounting position 302 of the plug assembly 1. The plug assembly 1 is installed in the plug mounting position 302, and the mounting base 300 is placed on the appliance body 100. The mounting base and the appliance body 100 are screwed together, thus assembling the plug assembly 1 and the appliance body 200 into a single unit.

[0078] The socket assembly 3 is fixed to the installation base 400, such as a ceiling, a suspended ceiling or a wall. Specifically, the expansion screw passes through the installation hole 2141 of the installation plate 214 to fix the second housing 21 to the installation base.

[0079] During installation of the electrical device, the plug assembly 1 and the socket assembly 2 are axially aligned, and the plug is then inserted into the socket. The electrical appliance body 100 is rotated while also rotating the first housing (here, clockwise) so that the first connecting arm is screwed into and engages with the slot of the second housing. Since the plug and socket have already been connected to the electrical appliance body and the external power source, respectively, during installation, the connection between the plug and the socket is a coupled power connection. This eliminates the need for additional wiring, saving steps and making installation quick and easy. Furthermore, the first connecting arm is engaged in the slot, requiring the first housing to be lifted and rotated to separate it from the second housing. This ensures a secure connection that is not easily loosened.

[0080] In some embodiments, the screwing direction of the first connecting arm is the same as the rotation direction of the wind wheel in the electrical appliance body; in other embodiments, the screwing direction of the first connecting arm may also be opposite to the rotation direction of the wind wheel in the electrical appliance body.

[0081] The electrical equipment provided by the utility model adopts an installation structure in which a plug assembly is screwed into and snap-connected to a socket assembly, which can eliminate the influence of radial reaction force and vibration existing in the electrical body during operation on the installation position and improve the installation stability of the electrical equipment.

[0082] The above content is merely an example and illustration of the structure of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these obvious alternative forms are all within the scope of protection of the present invention.
