Fig. 7A It is a schematic diagram of the ventilation fan of the utility model after installation. Figure 7B yes Fig. 7A A partial enlarged view of the A area. For clear illustration, Fig. 7A and Figure 7B The ceiling is hidden.

[0032] In the embodiment of the present utility model, Figure 6 , Fig. 7A and Figure 7B As shown, the ventilation fan 2000 includes a mounting portion 2000a arranged on the indoor opening side thereof. For example, the mounting portion 2000a can be a flange on the opening side of the ventilation fan. A detachably connected connector plate 2001 is also provided on the ventilation fan frame. The connector plate 2001 can be removed from the ventilation fan frame, thereby facilitating the installation and removal of the ventilation fan 2000 from the mounting bracket assembly 1000.

[0033] For example, the ventilating fan 2000 can be installed at a target installation position by means of the ventilating fan mounting bracket assembly 1000, and the target installation position can be, for example, a wooden beam, a steel beam, etc. The flange is formed on the indoor opening side of the ventilating fan frame opposite to the target installation position (such as a wooden beam), and extends a certain length outside the indoor opening side, and a flange mounting hole is provided on the flange.

[0034] The connector plate 2001 is provided with a connector plate opening, and the bottom of the connector plate is provided with a flange 2002 perpendicular to the connector plate. The flange 2002 of the connector plate is formed by bending the connector plate 2001 toward the outer periphery of the installation frame, and is used for detachable installation of the ventilation fan 2000 and the installation bracket combination 1000.

[0035] like Figure 2 and Figure 3 As shown in Figure 3 , the ventilation fan mounting bracket assembly 1000 of the present utility model includes a first bracket assembly 100 and a second bracket assembly 200. The first bracket assembly 100 has two groups. Each group of the first bracket assembly 100 includes a first bracket 110 fixed to a target installation position (e.g., a wooden beam) and a second bracket 120 connected to the first bracket 110. In this embodiment, the first bracket 110 is in a "U" shape, including a first connecting portion 111 fixed to the target installation position and a second connecting portion 112. The extending direction of the first connecting portion 111 and the extending direction of the second connecting portion 112 are perpendicular to each other. For example, the first connecting portion 111 is in a plate shape, the length direction of the first connecting portion 111 extends in the horizontal direction, and the plate surface of the first connecting portion 111 is perpendicular to the horizontal direction. The second connecting portion 112 also extends in the horizontal direction, and the extending directions of the first connecting portion 111 and the second connecting portion 112 are perpendicular. In this embodiment, the second connecting portion 112 is provided with two, and the two second connecting portions 112 are respectively arranged at both ends of the extending direction of the first connecting portion 111, so that the first bracket forms a "U" shape.

[0036] In an alternative embodiment of the present utility model, the second connecting portion can be provided with more than two, so as to meet the installation requirements of ventilation fans of different sizes or weights.

[0037] The first connecting portion 111 is provided with an opening 1110 extending along a direction perpendicular to the extending directions of the first connecting portion 111 and the second connecting portion 112. The opening 1110 includes a first opening 1111 and a second opening 1112. The first opening 1111 is farther from the second connecting portion 112 than the second opening 1112. For example, the first opening 1111 is located above the second opening 1112.

[0038] As Figure 3 shown, the first connecting portion 111 forms a flat plate shape in the vertical direction. The first connecting portion 111 is provided with a plurality of openings 1110 with different heights, such as openings arranged and extending in the vertical direction. These openings at least include a first opening 1111 with a higher height and a second opening 1112 with a lower height, that is, the first opening 1111 is farther from the second connecting portion 112, and the second opening 1112 is closer to the second connecting portion 112. The installer uses screws to penetrate the openings 1110 of the first connecting portion 111, thereby fixing the first connecting portion 111 to the target installation position (e.g., a wooden beam), and can freely select a convenient opening for operation. For example, when the surface of the target installation position is uneven and it is not convenient to drive screws, the opening corresponding to the uneven portion can be avoided, and another opening can be selected for installation.

[0039] The second bracket 120 is in a "U" shape, including a third connecting portion 121 connected to the second connecting portion 112, and a first mounting plate 122 disposed perpendicular to the extending direction of the third connecting portion 121 and matingly mounted with the mounting portion 2000a (such as a flange) of the ventilation fan 2000.

[0040] For example, the third connecting portion 121 includes two, and the two third connecting portions 121 are respectively disposed at both ends in the extending direction of the first mounting plate 122, and the two third connecting portions 121 are respectively connected to the two second connecting portions 112. The first mounting plate 122 is connected to the flange of the ventilation fan 2000. The third connecting portion 121 forms a flat plate shape placed in the horizontal direction and extends in the horizontal direction, and the extending directions of the second connecting portion 120 and the third connecting portion 121 are the same. Among the second connecting portion 112 and the third connecting portion 121, one is provided with a long strip-shaped connecting hole, and the other is provided with a connecting round hole.

[0041] For example, in this embodiment, taking the example that two long strip-shaped connecting holes 1121 are provided on the second connecting portion 112 and a plurality of connecting round holes 1211 are provided on the third connecting portion 121. When the first bracket 110 and the second bracket 120 are installed together, the second connecting portion 112 can be stacked above the third connecting portion 121, and by adjusting the length of the overlapping position, the length of the combination of the first bracket 110 and the second bracket 120 can be adjusted. For example, increasing the length of the overlapping position and making the first bracket 110 and the second bracket 120 closer to each other can shorten the length of the combination of the first bracket 110 and the second bracket 120; on the contrary, reducing the length of the overlapping position and making the first bracket 110 and the second bracket 120 farther away from each other can increase the length of the combination of the first bracket 110 and the second bracket 120. And because there are long strip-shaped connecting holes 1121 on the second connecting portion 112 and two or more connecting round holes 1211 on the third connecting portion 121, it is convenient to find the overlapping holes in the overlapping part of the second connecting portion 112 and the third connecting portion 121, and then screw in the screws to fix the first bracket 110 and the second bracket 120 together with the screws. In this way, the installer can adjust the overlapping length of the second connecting portion 112 and the third connecting portion 121 in the first bracket 110 and the second bracket 120 according to the distance between the two wooden beams, so as to adjust the length of the combination of the first bracket 110 and the second bracket 120, make the installation bracket combination 1000 adapt to wooden beams with different distances, and improve the convenience of installing the ventilation fan.

[0042] Such as Figure 2 and Figure 3As shown, the second connection part 112 is provided with a hole 1121 , and the third connection part 121 is provided with a hole 1211 . The second connection part 112 and the third connection part 121 are connected and fixed by passing a screw through the hole 1121 and the hole 1211 .

[0043] In some embodiments of the utility model, there may be more than two long strip-shaped connecting holes, which are arranged at intervals in the extension direction of the second connecting part or the third connecting part. There are two or more connecting circular holes, which are arranged at intervals in the extension direction of the second connecting part or the third connecting part.

[0044] For example, when the second connection part is provided with a long strip connection hole, the third connection part is provided with a connection circular hole, and when the second connection part is provided with a connection circular hole, the third connection part is provided with a long strip connection hole. The number of the long strip connection holes and the connection circular holes can be adjusted according to actual installation requirements.

[0045] In some embodiments, Figure 4 As shown, when the target installation position is narrow, for example, when the distance between two opposing wooden beams is short, even if the second connection part 112 and the third connection part 121 are completely overlapped, the length of the first bracket 110 and the second bracket 120 after being combined together is still too long and cannot meet the installation requirements. Therefore, further, a first groove 1122 is provided on the second connection part 112, which is recessed toward the inner side of its flat plate shape. There are two first grooves 1122, which are relatively arranged on the second connection part 112 and are located between the long strip connection holes arranged at intervals or between the connection circular holes arranged at intervals. The second connection part 112 can be cut off along the two opposite first grooves 1122 by using a tool, and the length of the second connection part 112 can be shortened. Specifically, two long strip connection holes 1121 on the second connection part 112 can be provided, and they are arranged at intervals along the length direction of the second connection part 112. The first groove 1122 is provided at a position between the two long strip connection holes 1121. In this way, even if the second connection portion 112 is cut off, the long strip-shaped connection hole 1121 will not be damaged, and the long strip-shaped connection hole 1121 in the remaining second connection portion 112 can still be used for installation.

[0046] like Figure 5As shown, the third connecting part 121 is provided with a second groove 1212 recessed toward the inner side of its flat plate shape, and there are two second grooves 1212, which are arranged on the third connecting part 121 relatively, and the second grooves 1212 are located between the long strip connecting holes arranged at intervals or between the connecting circular holes arranged at intervals. The length of the third connecting part 121 can be shortened by cutting off the third connecting part 121 along the two opposite second grooves 1212 using a tool. Specifically, the third connecting part 121 can be provided with 7 connecting circular holes 1211, and the second groove 1212 is arranged at a position close to the middle of the third connecting part 121, such as between the 3rd and 4th connecting circular holes 1211. In this way, even if the third connecting part 121 is cut off, the remaining multiple connecting circular holes 1211 in the third connecting part 121 can still be used for installation. After the second connection part 112 and the third connection part 121 are cut off respectively, the end of the second connection part 112 close to the first connection part 111 and the end of the third connection part 121 close to the second bracket 120 can be closer, so that the length of the first bracket 110 and the second bracket 120 after being combined together is further shortened, thereby adapting to the narrow installation space between the wooden beams. In addition, by replacing the telescopic structure of the background technology by cutting, the manufacturing cost of the mounting bracket combination can be effectively reduced.

[0047] like Figure 5 As shown, the extension direction of the first mounting plate 122 is perpendicular to the extension direction of the third connection portion 121. The first mounting plate 122 includes a first folded edge 1221 abutting against the side of the mounting portion 2000a of the ventilating fan 2000 and a second folded edge 1222 abutting against the bottom of the mounting portion 2000a of the ventilating fan 2000. For example, the first folded edge 1221 is formed by bending from the end of the third connection portion 121 in a vertical direction, and the first folded edge 1221 is perpendicular to the second folded edge 1222. The first folded edge 1221 is provided with a first folded edge opening 1221a connected to the second bracket assembly 200; the second folded edge 1222 is provided with a second folded edge opening 1222a connected to the mounting portion 2000a (such as a flange) of the ventilating fan 2000.

[0048] like Figure 2 and Figure 3As shown, the second bracket assembly 200 is arranged between the two groups of first bracket assemblies 100, and is used to connect the two groups of first bracket assemblies 100. The second bracket assembly 200 includes an intermediate mounting plate 210 arranged opposite to each other, and the end of the intermediate mounting plate 210 is connected to the third connecting portion 121, so that the intermediate mounting plate 210 and the third connecting portion 121 together constitute a mounting frame surrounding the ventilating fan frame. The length of the intermediate mounting plate 210 is consistent with the length or width of the ventilating fan, for example, the length of the intermediate mounting plate 210 is consistent with the side length of the mounting joint of the ventilating fan frame. The length of the first mounting plate 122 is consistent with the length of the two sides of the ventilating fan frame opposite to the wooden beam. In this way, after the end of the intermediate mounting plate 210 is connected to the first mounting plate 122, it can form a mounting frame that just surrounds the electrical appliance frame together with the first mounting plate 122.

[0049] In some embodiments of the present invention, the intermediate mounting plate 210 includes mounting folds 211 disposed at both ends of the intermediate mounting plate 210 and mounted in close contact with the first fold 1221, and mounting fold openings 2111 are disposed on the mounting fold 211. For example, the intermediate mounting plate 210 is roughly formed into a flat plate shape placed in a vertical direction, and the two ends of the flat plate shape are bent to form two end faces, and the end faces are provided with mounting fold openings 2111. The intermediate mounting plate 210 and the first mounting plate 122 can be connected to each other by screws penetrating the mounting fold openings 2111 and the first fold openings 1221a at corresponding positions of the first fold 1221 of the first mounting plate 122, thereby realizing the connection between the intermediate mounting plate 210 and the second bracket 120.

[0050] like Figure 6 , Fig. 7A and Figure 7B As shown, each intermediate mounting plate 210 is provided with a mounting hole 2101, and the mounting hole 2101 is used to connect with a detachable connector plate 2001 on the ventilating fan 2000 to fix the ventilating fan 2000 to the mounting frame. For example, the mounting hole 2101 is provided at the middle position of the intermediate mounting plate 210.

[0051] The bottom of the middle mounting plate 210 abuts against the flange 2002 of the connector plate 2001 that is bent toward the outer periphery of the mounting frame. For example, the connector plate 2001 is provided with a connector plate opening, and the connector plate 2001 has a flange 2002 that is bent toward the outer periphery of the mounting frame. During installation, the mounting hole 2101 of the middle mounting plate 210 is aligned with the connector plate opening of the connector plate 2001, and screws are passed through the connector plate opening and the mounting hole 2101. At the same time, the flange 2002 abuts against the bottom of the middle mounting plate 210, thereby achieving the limit of the ventilation fan.

[0052] As described above, the structures of the two groups of first bracket components 100 can be set to be the same, that is, they can share a set of molds, thereby saving the cost of mold production.

[0053] like Figure 6 and Fig. 7A As shown, by using the above structure, the ventilation fan 2000 can be installed between two opposite wooden beams 1000b. Specifically, first, according to the size of the ventilation fan frame, an opening of the same size as or slightly larger than the ventilation fan frame is sawed on the ceiling 1000a located below the wooden beam 1000b. Then, the distance between the wooden beam 1000b and the edge of the opening is measured. This distance is used to determine the length of the first bracket 110 and the second bracket 120 after being combined together. According to this distance, the length of the overlapping position of the second connecting part 112 and the third connecting part 121 is adjusted. The first bracket 110 and the second bracket 120 are fixed together by screws penetrating the long strip connecting hole 1121 on the second connecting part 112 and the connecting circular hole 1211 on the third connecting part 121. If the distance between the two wooden beams 1000b is short, use a tool to cut off the second connection part 112 along the two opposite first grooves 1122, and cut off the third connection part 121 along the two opposite second grooves 1212, and then overlap the remaining second connection part 112 and the remaining third connection part 121. Similarly, screws are passed through the long strip connection hole 1121 on the second connection part 112 and the connection circular hole 1211 on the third connection part 121, so that the first bracket 110 and the second bracket 120 are fixed together.

[0054] After the first bracket 110 and the second bracket 120 are fixed together, screws can be used to penetrate the installation folded edge opening 2111 of the middle mounting plate 210 and the first folded edge opening 1221a on the first folded edge 1221 to connect the second bracket assembly 200 and the first bracket assembly 100 together.

[0055] Next, the mounting bracket assembly 1000 of the ventilation fan 2000 is passed as a whole over the top of the ceiling opening, the mounting frame formed by the middle mounting plate 210 and the first mounting plate 122 is placed on the edge of the ceiling opening, the first connecting portion 111 is pressed tightly against the wooden beam 1000b, and screws are passed through the openings 1110 on the first connecting portion 111, such as the first opening 1111 and / or the second opening 1112 and the wooden beam 1000b, thereby fixing the ventilation fan mounting bracket assembly 1000 between the wooden beams 1000b.

[0056] Then, the connector plate 2001 is placed on any one of the intermediate mounting plates 210, the positioning flange 2002 provided at the bottom of the connector plate is clamped under the ceiling opening, screws are passed through the mounting holes 2101 on the intermediate mounting plate 210 and the connector plate openings on the connector plate 2001, and the connector plate 2001 is fixed to the second bracket assembly 200, so as to fix the ventilating fan 2000 to the mounting frame. Then, the ventilating fan frame is adjusted to a direction where its flange is located below the first mounting plate, and the ventilating fan frame is passed through the ceiling opening from below the ceiling opening, the flange is clamped under the ceiling opening, and screws are passed through the flange mounting holes and the second folded edge openings 1222a of the second bracket 120, so as to fix the ventilating fan frame to the mounting bracket assembly, and the installation is completed.

[0057] So far, the embodiments of the present invention have been described in detail in conjunction with the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the present invention.

[0058] It should be noted that the implementation methods not shown or described in the drawings or the text of the specification are all forms known to ordinary technicians in the relevant technical field and are not described in detail.
