Description

Technical Field

[0001] The utility model belongs to the technical field of wall-mounted fan installation structures, and in particular relates to an electrical box component for a wall-mounted fan. Background Art

[0002] Wall-mounted fans are used in high-end residences, office buildings, hotel lobbies, factories, and canteens. They mainly include three components: motor, wall-mounted bracket assembly, and fan blades. The wall-mounted bracket assembly is the key component to ensure the safe use of wall-mounted fans. At present, the installation structure of wall-mounted fans on the market has the following defects:

[0003] 1. The wall-mounted brackets of wall-mounted fans currently sold on the market use holes opened at the rear of the plastic electrical box and use the main body as a pendant. There is a lack of effective evaluation of the bearing strength of the wall-mounted structure. For wall-mounted fans that need to bear a large weight, it is difficult to ensure the reliability and safety of the product during long-term operation.

[0004] 2. The electrical box of the wall-mounted fans currently sold on the market is integrated into the wall-mounted parts, and the pull-cord switch is installed using self-tapping screws. When the pull-cord switch adjusts the gear position, it is only supported by the switch fixing screws on the wall-mounted parts. It is difficult to ensure the reliability and safety of the product in long-term operation.

[0005] 3. The electrical box of the wall-mounted fans currently sold on the market is integrated into the wall-mounted part, and the installation position of the switch is at a certain angle to the pull cord hole. When the pull cord is pulled, friction occurs between the pull cord and the electrical box. Long-term friction can easily cause the pull cord to break.

[0006] 4. Currently, the power cords of wall-mounted fans sold on the market are mostly fixed by wire buckles. The wire buckles fix the power cords, and the wire buckles are installed in an extrusion manner. The power cords on the market are of different thicknesses. A too thick power cord will cause the power cord to be squeezed too much, causing the power cord to age and burn out. If a too thin power cord is installed with a wire buckle, the power cord cannot be reliably fixed, causing the power cord to fall off, and it is difficult to ensure the reliability and safety of the product in long-term operation.

[0007] 5. The pitch adjustment of wall-mounted fans currently sold on the market is mostly fixed by clamping plastic wall-mounted parts and plastic trays. There is no fixed limit, which makes it easy for them to loosen during use, resulting in loss of limit and drooping of the fan head. It is difficult to ensure the reliability and safety of the product during long-term operation. Utility Model Content

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] Example:

[0042] like Figure 1-8As shown, in this embodiment, an electrical box assembly for a wall-mounted fan is provided, which includes a wall-mounted member 20, an electrical box 30, and a tray 10. To show the structure of the electrical box, among them Figure 1 the structure of a bracket side plate is hidden, and this is hereby explained

[0043] The electrical box 30 is connected to the wall-mounted member 20. There are two or more switch mounting parts in the electrical box 30, and the switch mounting parts are used to fix the switch device of the wall-mounted fan;

[0044] The tray 10 is rotatably hinged to the wall-mounted member 20, and a fixing device for restricting the relative rotation of the tray 10 and the wall-mounted member 20 is provided at the hinge joint of the tray 10 and the wall-mounted member 20.

[0045] In this embodiment, the number of switch mounting parts is two, including a first switch mounting part and a second switch mounting part. The first switch mounting part is used to mount the speed regulation switch device 3022, and the second switch mounting part is used to mount the swing switch device 3023, ensuring the stability of the fixing of each switch device in the electrical box 30, improving the service life. At the same time, the structure of the relative rotational hinge fit between the tray 10 and the wall-mounted member 20 can perform a simple pitching angle adjustment on the wall-mounted fan, overcoming the risk of loosening and losing the limit that easily occurs in the existing clamping fixing method.

[0046] The specific structure of the wall-mounted member 20 in this embodiment is as follows:

[0047] The wall-mounted member 20 includes a mounting base plate 201, a fixing boss 2011, and an assembly bracket 202. The fixing boss 2011 is connected to the assembly bracket 202, and the assembly bracket 202 is connected to the electrical box 30 and rotatably hinged to the tray 10.

[0048] Specifically, the mounting base plates 201 are arranged on both sides of the fixing boss 2011. Mounting holes 2012 are provided on the mounting base plates 201, and first press-fitting holes 2013 for connecting the assembly bracket 202 are provided on the fixing boss 2011.

[0049] Specifically, the assembly bracket 202 is a U-shaped structure, including a bracket base plate and bracket side plates. The bracket side plates are symmetrically arranged at both ends of the bracket base plate. Second press-fitting holes 2021 for connecting the fixing boss 2011 are provided on the bracket base plate. Mounting holes 2022 for fixing the electrical box 30 are provided on the bracket side plates. Angle limiting grooves 2024 and first connection holes 2025 are provided on the bracket side plates. A screw assembly connected to the tray 10 is provided on the first connection hole 2025, and the angle limiting grooves 2024 are slidably engaged with the tray 10.

[0050] Specifically, the angle limiting groove 2024 is an arc-shaped structure, and there are two angle limiting grooves 2024 . The two angle limiting grooves 2024 are radially arranged with the first connecting hole 2025 as the center.

[0051] In the above structure, the mounting base plate 201 of the wall-mounted component 20 is fixed to the wall through the rivet structure set in the mounting hole 2012, wherein the mounting hole 2012 is a double circular structure with a larger bottom and a smaller top. The set fixing boss 2011 can avoid the rivet part set on the first press-fit hole 2013 of the fixing boss 2011. After being fixed with the second press-fit hole 2021 of the bracket base plate, the protruding part of the rivet part causes the unevenness of the installation and fixing surface between the wall-mounted component 20 and the wall. In addition, since the fixing boss 2011 is designed to protrude upward, the contact area between the fixing boss 2011 of the wall-mounted component 20 and the wall is reduced, so that the mounting base plate 201 can fit the wall better after hanging. The riveted structure used in this embodiment further improves the fixing reliability of the fan and the wall.

[0052] The specific structure of the relative rotation hinged connection between the tray 10 and the wall hanging member 20 is as follows:

[0053] The tray 10 is provided with a second connecting hole 1012, a motor connecting hole 1010, a connecting rod mounting column 1011 and a limit mounting hole 20221013. The second connecting hole 1012 corresponds to the position of the first connecting hole 2025. The limit mounting hole 20221013 is provided with a limit piece that slides with the angle limit groove 2024.

[0054] The motor connecting hole 1010 of the tray 10 is connected to the motor of the fan, and a connecting rod member is arranged on the connecting rod mounting column 1011 to link with the motor of the fan to realize the shaking function of the fan; the second connecting hole 1012 of the tray 10 is provided with a screw assembly matching the first connecting hole 2025 of the bracket side plate, and the limiting member on the limiting mounting hole 20221013 slides in the angle limiting groove 2024 to realize the pitch angle adjustment function. This embodiment uses integrated angle adjustment and is connected to the motor of the fan at the same time. It has an integrated structural design with a linked shaking angle, which further improves the reliability of the fan.

[0055] The specific structure of the electrical box 30 of this embodiment is as follows:

[0056] The electrical box 30 includes a cavity, and a first switch mounting portion and a second switch mounting portion are provided in the cavity of the electrical box 30;

[0057] The first switch mounting portion includes a switch positioning column 3012, a switch inverted buckle 3013 and a switch support column 3014. The number of the switch inverted buckles 3013 is more than two, and a buckle area is formed between adjacent switch inverted buckles 3013. The switch support column 3014 is in the buckle area.

[0058] The second switch mounting portion is provided with a switch slot 3016 and a fixed mounting hole 3015 .

[0059] In the above structure, the first switch mounting portion is used to install the speed regulating switch device 3022, and the second switch mounting portion is used to install the shaking head switch device 3023, wherein the speed regulating switch device 3022 is installed by pressing along the switch positioning column 3012 to the buckle area formed by the switch inverted buckle 3013, and the installation is completed to ensure that the switch is installed in place, and a switch support column 3014 is provided under the speed regulating switch device 3022. When the speed regulating switch device 3022 is pulled, the switch positioning column 3012, the switch inverted buckle 3013 and the switch support column 3014 play a fixing role together, effectively preventing the speed regulating switch device 3022 from loosening and buckle failure. The switch quick installation structure used in this embodiment further improves the reliability of the fan.

[0060] The switch slot 3016 of the second switch installation part is used to install the shaking head switch device 3023. With the pressing force of the bracket side plate on the shaking head switch device 3023, the shaking head switch device 3023 can be fixed in all directions.

[0061] The cavity of the electrical box 30 of this embodiment is also provided with a double-layer clamping bayonet seat 3011 and an embedded limit seat 3017. The double-layer clamping bayonet seat 3011 is provided with a bayonet portion for fixing the power cord 3021, and the bayonet portion is provided with reinforcing ribs. The embedded limit seat 3017 is provided with a limit groove, and a pull rope guide bead 3024 is provided in the limit groove.

[0062] Specifically, the pull rope guide bead 3024 is in a spherical shape, and a central through hole is provided in the middle of the pull rope guide bead 3024 .

[0063] Specifically, a connecting column 3018 is further provided in the cavity of the electrical box 30 , and the connecting column is connected to the wall-mounted component 20 .

[0064] The pull rope guide bead 3024 cooperates with the pull rope member, and the pull rope member is connected to the speed control switch device 3022 and the shaking head switch device 3023. When the speed control switch device 3022 or the shaking head switch device 3023 is pulled by the pull rope member, the pull rope guide bead 3024 plays a guiding and protective role, which greatly reduces the friction and loss of the pull rope member. The structure of the pull rope guide bead 3024 in this embodiment further improves the reliability of the fan.

[0065] In summary, the electrical box assembly for the wall-mounted fan of this embodiment has a reasonable structural design, which not only realizes the limit adjustment of the pitch angle of the fan, but also is easy to install and has the advantages of high reliability.

[0066] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
