In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0040] Figure 1 is a schematic structural diagram of a fan installation device for quickly disassembling and assembling a fan in a fan wall according to an embodiment of the present invention, and in combination with Figures 2 - 7 , the present invention provides a fan installation device 200, including a quick disassembly and assembly device 300. The quick disassembly and assembly device 300 includes a first baffle 312, a rotating rod 332, and a first pressing plate 340.

[0041] The first baffle plate 312 is provided with a first through hole 320 perpendicular to the axis 130 of the fan. The first baffle plate 312 is fixedly connected to the housing 120 of the fan 100 through the first connecting frame 314. The rotating rod 332 rotatably passes through the first through hole 320. A second baffle plate 334 is provided at one end of the rotating rod 332 between the first baffle plate 312 and the housing 120, and the second baffle plate 334 and the first baffle plate 312 block each other in the axial direction of the first through hole 320. The peripheral wall of the rotating rod 332 is provided with a thread. The first pressing plate 340 is threadedly connected to the rotating rod 332 and is located on the side of the first baffle plate 312 that is away from the second baffle plate 334.

[0042] There are at least two quick disassembly devices 300, and at least two quick disassembly devices 300 are respectively arranged on opposite sides of the fan 100, so that when the two rotating rods 332 are rotated, the two first pressure plates 340 are driven to move closer to the middle and clamped on the partition frame 400 of the fan 100 wall.

[0043] The first connecting frame 314 can be fixed to the outer side of the housing 120 of the fan 100 by welding, fastener connection, etc. The first baffle 312 can be fixed to the first connecting frame 314 by welding, fastener connection, etc., or the first baffle 312 can be integrally formed with the first connecting frame 314. For example, the first baffle 312 and the first connecting frame 314 can be barrel-shaped as a whole, the first baffle 312 can constitute the bottom plate of the barrel, and the first connecting frame 314 can constitute the side wall of the barrel.

[0044] The first through hole 320 is opened on the first baffle plate 312 . An accommodating space is formed between the first baffle plate 312 and the first connecting frame 314 . The second baffle plate 334 is located in the accommodating space and can rotate around the axis of the first through hole 320 in the accommodating space.

[0045] The rotating rod 332 is rotatably inserted in the first through hole 320, one end of the rotating rod 332 is located in the accommodation space formed between the first baffle 312 and the first connecting frame 314, and the other end is located outside the first baffle 312. The axis of the rotating rod 332 is coaxial with the axis of the first through hole 320. The second baffle 334 can be fixed to the end of the rotating rod 332 close to the first connecting frame 314 by welding, fastener connection, etc. The size of the second baffle 334 is larger than the first through hole 320, so that when the rotating rod 332 is rotated, the second baffle 334 will rotate in the accommodation space, but will not be separated from the first through hole 320. The second baffle 334 can be round, square, polygonal, etc.

[0046] The first pressing plate 340 is located outside the first baffle 312, and threaded holes matching the threads on the outer periphery of the rotating rod 332 are provided on the first pressing plate 340. When the rotating rod 332 rotates, the first pressing plate 340 is driven to move along the axis of the rotating rod 332 through screw transmission. For example, when the rotating rod 332 rotates clockwise, the first pressing plate 340 can move away from the machine housing 120, that is, increase the distance between it and the machine housing 120; when the rotating rod 332 rotates counterclockwise, the first pressing plate 340 can reduce the distance between it and the machine housing 120.

[0047] A plurality of shelves 400 can be fixedly arranged on the fan 100 wall, and a fan 100 can be detachably and fixedly connected to each shelf 400. Of course, a frame can also be provided on the fan 100 wall, and a plurality of shelves 400 can be detachably and fixedly connected to the frame, and a fan 100 can be detachably and fixedly connected to each shelf 400. The shelf 400 is usually formed by processing metal profiles, for example, a rectangular shelf 400 is formed by welding four square tubes.

[0048] In this embodiment, at least two quick disassembly and assembly devices 300 are provided on the fan installation device 200 of each fan 100, and at least two of the quick disassembly and assembly devices 300 are respectively arranged on opposite sides of the machine housing 120. When installing the fan 100 on the shelf 400, by rotating the rotating rods 332 of the two quick disassembly and assembly devices 300 on both sides of the machine housing 120, the two first pressing plates 340 can be driven to move closer to each other and clamp on the opposite ends of the shelf 400. That is to say, the fixed connection of the fan 100 is realized by forming a squeezing force and a frictional force between the two first pressing plates 340 and the shelf 400, and the fan 100 can be quickly installed on the shelf 400. When disassembling, rotate the two rotating rods 332 in the opposite direction to separate the two first pressing plates 340 from the shelf 400, and the fan 100 can be quickly removed from the shelf 400.

[0049] It should be understood that the two quick disassembly and assembly devices 300 can be arranged on the left and right sides of the machine housing 120, or can be arranged on the upper and lower sides of the machine housing 120. Of course, the fan installation device 200 can also be provided with a plurality of quick disassembly and assembly devices 300. For example, quick disassembly and assembly devices 300 are arranged on both the left and right sides and the upper and lower sides of the machine housing 120 to further increase the squeezing force and frictional force formed between the first pressing plate 340 and the shelf 400 and enhance the connection strength between the fan 100 and the shelf 400.

[0050] The disassembly and assembly process of this fan installation device 200 is relatively simple and has a low operation difficulty. The fan 100 that needs to be repaired or replaced can be quickly removed from the shelf 400, and the intact fan 100 can be quickly installed on the shelf 400, having a high disassembly and assembly efficiency.

[0051] In some embodiments of the fan installation device of the present invention, such as Figure 3 andFigures 5 - 7 As shown, a first positioning groove 352 is provided at one end of the partition frame 400 close to the corresponding first pressing plate 340.

[0052] A first positioning block 354 is fixedly connected to one side of the first pressing plate 340 close to the corresponding second baffle 334. The first positioning block 354 is inserted and sleeved in the first positioning groove 352 along the axial direction of the first through hole 320.

[0053] When the fan 100 is working, vibrations will be generated. When the vibrations are relatively strong, it may affect the extrusion force and frictional force between the first pressing plate 340 and the partition frame 400, resulting in the fan 100 shifting or even detaching from the partition frame 400.

[0054] In this embodiment, in order to further improve the connection reliability between the first pressing plate 340 and the partition frame 400, the first positioning groove 352 and the first positioning block 354 are provided. The first positioning groove 352 is provided on the partition frame 400 and extends along the axis of the first through hole 320. The opening direction of the first positioning groove 352 faces the corresponding first pressing plate 340. The first positioning block 354 can be fixed to the side of the first pressing plate 340 facing the corresponding first positioning groove 352 by forms such as welding and fastener connection. Of course, the first positioning block 354 can also be formed on the first pressing plate 340. For example, the first positioning block 354 is formed by bending the end of the first pressing plate 340.

[0055] Before installation, the first positioning block 354 is outside the first positioning groove 352. During installation, as the rotating rod 332 rotates, the first pressing plate 340 moves towards the partition frame 400, and the first positioning block 354 is inserted into the first positioning groove 352. The inner wall of the first positioning groove 352 can limit and block the first positioning block 354, thereby limiting and blocking the fan 100 to prevent the fan 100 from shifting or even detaching from the partition frame 400.

[0056] In addition, the provision of the first positioning groove 352 and the first positioning block 354 also facilitates installation. It should be understood that when the rotating rod 332 is rotated, the first pressing plate 340 may rotate with the rotating rod 332, and the installer needs to restrict the rotation of the first pressing plate 340 by hand, tools, etc. In this embodiment, during the installation process, since at least part of the first positioning block 354 is inserted into the first positioning groove 352, the side wall of the first positioning groove 352 will block the rotation of the first positioning block 354 with the rotating rod 332. In this way, the disassembly and assembly process can be further simplified and the disassembly and assembly efficiency can be improved.

[0057] Of course, during the operation of the fan 100, the first positioning groove 352 will also limit the fan 100 to prevent the fan 100 from rotating relative to the partition frame 400 and improve the connection reliability of the fan 100.

[0058] In some other embodiments of the present invention, the first positioning groove 352 is provided on the side of the first pressing plate 340 close to the corresponding partition frame 400, and the first positioning block 354 is provided on the partition frame 400. Its structure and operating principle are similar to those of the previous embodiment and will not be elaborated here.

[0059] In some embodiments of the fan installation device of the present invention, as Figures 5 - 7 shown, the first positioning block 354 is connected to the first positioning groove 352 in a form-fitting insertion manner.

[0060] In this embodiment, the cross-sections of the first positioning groove 352 and the first positioning block 354 can be rectangular, polygonal, etc. In this way, when the first positioning block 354 is inserted into the first positioning groove 352, the two will not rotate around the axis of the first through hole 320. That is to say, the fan 100 can be prevented from rotating relative to the partition frame 400, thereby further improving the connection reliability between the fan 100 and the partition frame 400.

[0061] In some embodiments of the fan installation device of the present invention, as Figure 7 shown, a turntable 336 is coaxially and fixedly connected to the end of the rotating rod 332 away from the second baffle 334. The outer diameter of the turntable 336 is larger than the outer diameter of the rotating rod 332.

[0062] In the axial direction of the first through hole 320, the distance L1 between the first pressing plate 340 and the turntable 336 is greater than the height L2 of the first positioning block 354.

[0063] The second baffle 334 and the turntable 336 can be located at opposite ends of the rotating rod 332. The turntable 336 has a relatively large outer diameter. On the one hand, it is convenient for the installer to directly drive the rotating rod 332 to rotate by rotating the turntable 336, eliminating the need to use tools such as wrenches, further simplifying the disassembly and assembly process, and improving the disassembly and assembly efficiency. On the other hand, the turntable 336 also forms a stop for the first pressing plate 340 to prevent the first pressing plate 340 from detaching from the rotating rod 332.

[0064] It should be understood that the distance between the fans 100 in the fan 100 wall is relatively small, and the operating space during disassembly and assembly is small. After the turntable 336 is provided, no matter how the rotating rod 332 rotates, the first pressing plate 340 cannot detach from the rotating rod 332, effectively preventing the first pressing plate 340 from falling or being lost. If the turntable 336 is not provided, during the disassembly and assembly process, the first pressing plate 340 may fall off from the end of the rotating rod 332 away from the second baffle 334 and fall into the lower fan 100, causing unnecessary trouble.

[0065] The distance L1 between the first pressing plate 340 and the turntable 336 is greater than the height L2 of the first positioning block 354, such that the top end of the first positioning block 354 can be located outside the opening of the first positioning groove 352 before installation. During installation, there is no need to additionally adjust the position or angle of the casing 120 or the first pressing plate 340. Just align the first positioning block 354 with the first positioning groove 352. During disassembly, the first positioning block 354 can be pulled outwards to completely disengage from the first positioning groove 352, facilitating the direct removal of the casing 120.

[0066] In some embodiments of the fan installation device of the present invention, as Figure 7 shown, a second positioning groove 362 is provided at one end of the turntable 336 away from the second baffle 334. The second positioning groove 362 is a circular blind hole and is coaxial with the turntable 336.

[0067] The quick disassembly and assembly device 300 further includes a positioning post 364 and a second positioning block 366. One end of the positioning post 364 is fixedly connected to the casing 120, and the other end is fixedly connected to the second positioning block 366. The second positioning block 366 is cylindrical and is coaxially inserted and sleeved in the second positioning groove 362.

[0068] The positioning post 364 can be fixedly connected to the casing 120 in forms such as welding or fastener connection. The positioning post 364 can be arranged close to the first connecting frame 314. Of course, the positioning post 364 can also be directly fixedly connected to the first connecting frame 314 or integrally formed with the first connecting frame 314. In this way, it helps to improve the coaxiality between the second positioning block 366 and the first through hole 320.

[0069] In this embodiment, the second positioning groove 362 and the second positioning block 366 are used to limit the rotating rod 332, such that the axis of the rotating rod 332 always remains coaxial with the axis of the first through hole 320. Without the second positioning groove 362 and the second positioning block 366, the first through hole 320 may require a relatively thick hole depth, or the clearance fit between the first through hole 320 and the rotating rod 332 needs to be relatively precise to ensure that the axis of the rotating rod 332 always remains coaxial with the axis of the first through hole 320.

[0070] In some other embodiments of the present invention, the second positioning groove 362 is provided on the positioning post 364, and the second positioning block 366 is fixedly connected to the end of the turntable 336 away from the rotating rod 332. Its structure and operating principle are similar to those of the previous embodiment and will not be elaborated here.

[0071] In some embodiments of the fan installation device of the present invention, as Figure 1 、 Figure 5 and Figure 7As shown, a first chute 372 is formed in the positioning post 364. The opening of the first chute 372 faces the rotating rod 332, and the first chute 372 extends along the axial direction of the first through hole 320. A first slider 374 is fixedly connected to the first pressing plate 340, and the first slider 374 is slidably connected within the first chute 372.

[0072] The first slider 374 can be fixed to the first pressing plate 340 by means such as welding or fastener connection. Of course, the first slider 374 can also be formed on the first pressing plate 340. For example, the first slider 374 is machined from the first pressing plate 340 by processes such as turning.

[0073] The first slider 374 is slidably connected within the first chute 372, and the first chute 372 positions, stops, and guides the first slider 374. On the one hand, when the rotating rod 332 is rotated, the first chute 372 can stop the first slider 374 from rotating around the axis of the first rotating rod 332. That is to say, the first chute 372 can prevent the first pressing plate 340 from rotating relative to the machine housing 120, thereby improving the disassembly and assembly efficiency. On the other hand, when the first slider 374 moves along the axis of the rotating rod 332 with the first pressing plate 340, the first chute 372 can guide the trajectory of the first slider 374. That is to say, the first chute 372 can prompt the first pressing plate 340 to move in a straight line, thereby increasing or decreasing the vertical distance between the first pressing plate 340 and the partition frame 400.

[0074] In some embodiments of the fan installation device of the present invention, as Figure 7 shown, in the axial direction of the axis 130 of the fan, the first slider 374 and the first positioning block 354 are respectively located at opposite ends of the first pressing plate 340. Thus, when the first pressing plate 340 moves along the axis of the rotating rod 332, the first pressing plate 340 can be positioned from two opposite directions of the first pressing plate 340, prompting the first pressing plate 340 to always be parallel to the machine housing 120. On the other hand, it can also make the structure of the quick disassembly and assembly device 300 more compact, reducing the space volume and the operating space during disassembly and assembly.

[0075] In some embodiments of the fan installation device of the present invention, as Figure 7 shown, both the first baffle 312 and the second baffle 334 are circular and are coaxial with the axis of the first through hole 320. The first connecting frame 314 is tubular and is coaxial with the axis of the first through hole 320.

[0076] In this embodiment, the first connecting frame 314 can be directly processed from a round tube, and the first baffle 312 can be directly welded to one end of the round tube. This structure is convenient for processing and has a relatively low manufacturing cost. When the rotating rod 332 is rotated, the first through hole 320 can limit the rotating rod 332, and the inner wall of the first connecting frame 314 can also slide and limit the peripheral wall of the second baffle 334, so that the axis of the rotating rod 332 is kept coaxial with the axis of the first through hole 320.

[0077] In some embodiments of the fan installation device of the present invention, such as Figure 1 shown, the partition frame 400 is in a rectangular frame shape and includes two longitudinal partition beams 410 arranged at intervals in the horizontal direction and two transverse partition beams 420 arranged at intervals in the vertical direction. The two first pressing plates 340 of the two quick-disassembly devices 300 are respectively clamped at the left end of the left longitudinal partition beam 410 and the right end of the right longitudinal partition beam 410.

[0078] At the top of the upper transverse partition beam 420, there is a third positioning groove 382 with an upward opening. The top of the casing 120 is also fixedly connected with a downwardly protruding third positioning block 384. The profile of the third positioning block 384 is inserted and connected in the third positioning groove 382.

[0079] A ventilation channel is formed in the middle of the rectangular frame. The two first pressing plates 340 respectively clamp the two longitudinal partition beams 410 from the left and right inner sides. The profile of the third positioning block 384 is inserted and connected to the third positioning groove 382. On the one hand, the transverse partition beam 420 or the third positioning groove 382 supports the third positioning block 384 upward, that is, shares part of the weight of the fan 100. On the other hand, the third positioning groove 382 limits the third positioning block 384, so that the third positioning block 384 cannot rotate in the third positioning groove 382 around the vertical axis. That is to say, the third positioning groove 382 can prevent the fan 100 from rotating relative to the partition frame 400 around the vertical axis, thereby improving the connection reliability of the fan 100.

[0080] On the other hand, during installation, the third positioning block 384 can be first inserted and connected in the third positioning groove 382. At this time, the weight of the fan 100 is borne by the transverse partition beam 420, and the installer does not need to additionally support the fan 100 and only needs to focus on operating the rotating rod 332 and the first pressing plate 340. In this way, the disassembly and assembly process can be further simplified and the disassembly and assembly efficiency can be improved.

[0081] In some embodiments of the fan 100 of the present invention, such as Figure 1 shown, the fan 100 includes a casing 120 and the fan installation device 200 of any one of the above embodiments or a combination of embodiments. A wind wheel 110 is rotatably connected in the casing 120. The axis of the wind wheel 110 is the axis 130 of the fan.

[0082] The fan 100 of this embodiment can be conveniently and quickly installed on the partition rack 400, and can also be conveniently and quickly disassembled from the partition rack 400. The partition rack 400 can be detachably and fixedly connected to the rack on the wall of the fan 100 through a plurality of fasteners.

[0083] There are multiple exemplary embodiments of the present invention. However, without departing from the spirit and scope of the present invention, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
