[0023] Specifically, the lifting and rotating device 3 includes a connecting column 31, a first threaded hole 32, a connecting sleeve 33, a first screw 34, a rotating assembly 35 and a connecting frame 36. The connecting column 31 is installed between the bottom plate 1 and the top plate 5 and at a position on one side of the fan body 8. A connecting sleeve 33 is provided on the outside of the connecting column 31. The connecting frame 36 is installed on the side of the connecting sleeve 33 close to the fan body 8 and at a position outside the fan body 8 and the mounting plate 7. The first screw 34 is threadedly installed on the side of the connecting sleeve 33 away from the connecting frame 36. A plurality of first threaded holes 32 are provided on the side of the connecting column 31 away from the connecting frame 36, and a rotating assembly 35 is installed on the top of the connecting frame 36.

[0024] By adopting the above technical solution, the staff can adjust the height of the fan body 8 to a certain extent through the cooperation of the connecting frame 36 and the connecting column 31 and other structures when necessary, so as to better meet the working needs in different situations.

[0025] Specifically, the rotating assembly 35 includes a connecting shaft 351 and a rotating plate 353 . The connecting shaft 351 is installed on the top of the connecting frame 36 via a bearing, and the rotating plate 353 is installed above the connecting shaft 351 .

[0026] By adopting the above technical solution, the staff can adjust the direction of the fan body 8 to a certain extent through the cooperation of the connecting frame 36 and the connecting shaft 351 and other structures when necessary, so as to better meet the working needs in different situations.

[0027] Specifically, the rotating assembly 35 also includes a second screw 352 and a second threaded hole 354 . The second screw 352 is threadedly installed on the top of the connecting frame 36 and located on one side of the connecting shaft 351 . A plurality of second threaded holes 354 are opened near the edge of the rotating plate 353 .

[0028] By adopting the above technical solution, the staff can fix the relative position between the connecting frame 36 and the rotating plate 353 by cooperating with the second screw 352 and the second threaded hole 354 when necessary, thereby preventing the rotating plate 353 and the fan body 8 and other structures from continuing to rotate.

[0029] When this embodiment is used, when it is necessary to use the device to fix the duct fan of the ventilation equipment, the mounting plate 7 and the fan body 8 are connected by screws, and then the positions of the top plate 5 and the bottom plate 1 are fixed by the two mounting mechanisms 4 and each buffer component 2, and then the connecting sleeve 33 in the lifting and rotating device 3 is pulled to drive the connecting frame 36 and the fan body 8 and other structures to move along the connecting column 31 to the required height, and then the first screw 34 is rotated to connect it with the corresponding first threaded hole 32, and then the fan body 8 is rotated to rotate it around the connecting shaft 351 in the rotating component 35 to the required direction, and then the second screw 352 is rotated to connect it with the second threaded hole 354 on the rotating plate 353 above the connecting shaft 351, and the fixing work is completed.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the position adjustment device 6 includes a fixed box 61, a knob 62, a screw rod 63 and a moving block 64, the fixed box 61 is installed on the side of the connecting shaft 351 close to the mounting plate 7, the screw rod 63 is installed at the central position of the fixed box 61 through a bearing, the knob 62 is installed on one side of the screw rod 63, and the moving block 64 is installed above the mounting plate 7 and at a position located on the outside of the screw rod 63 and the inside of the fixed box 61.

[0032] By adopting the above technical solution, the staff can adjust the position of the fan body 8 to a certain extent by cooperating with the screw rod 63, the moving block 64 and other structures when necessary, so as to better meet the working needs in different situations.

[0033] Specifically, the height of the inner top surface of the fixed box 61 is equal to the height of the outer top surface of the moving block 64 .

[0034] By adopting the above technical solution, the device can ensure that the inner top surface of the fixed box 61 can be in close contact with the outer top surface of the moving block 64, thereby preventing the moving block 64 from rotating and deviating during movement.

[0035] When this embodiment is used, when the position of the fan body 8 needs to be adjusted, the knob 62 in the position adjustment device 6 is rotated, and the knob 62 drives the screw rod 63 to rotate. The screw rod 63 is threadedly connected to the moving block 64, and the outer top surface of the moving block 64 is close to the inner top surface of the fixed box 61, so the screw rod 63 drives the moving block 64 and the mounting plate 7 thereunder to move, thereby adjusting the position of the fan body 8, thereby better meeting the working needs in different situations.

[0036] The structure and principle of the buffer assembly 2, the mounting mechanism 4, the top plate 5, and the fan body 8 in the utility model have been disclosed in a duct fan fixing device for ventilation equipment disclosed in Chinese patent application No. 202021798795.2. Its working principle is that when preparing for installation, the protective plate is first fixedly installed on the predetermined position on the ground, and then the fixing frame is fixedly installed on the wall, and the fan body is installed from top to bottom, so that the bottom base of the fan body is aligned with the slot and inserted, and the movable block is squeezed, so that one end of the movable block slides inward by the elastic force of the reset spring until the base is fully seated. When it is completely pushed into the slot, the movable block squeezes and fixes the base through the elastic force of the reset spring itself. At the same time, the receiving grooves on both sides of the top plate just rest against the top of the fixed frame. Then the worker holds the threaded rod and rotates it clockwise, so that the sliding sleeve on the surface of the threaded rod drives the fixed rod to slide along the sliding groove through the slider until the fixed rod is in a vertical state and is stuck in the inner groove of the receiving groove. When disassembly is required, as described above, the threaded rod is rotated counterclockwise, so that the sliding sleeve on the surface of the threaded rod drives the fixed rod to slide along the sliding groove through the slider until the fixed rod is in a tilted state, and the fan body can be removed as a whole.

[0037] The working principle and use process of the utility model are as follows: when the device is needed to fix the duct fan of the ventilation equipment, the mounting plate 7 and the fan body 8 are connected by screws, and then the positions of the top plate 5 and the bottom plate 1 are fixed by two mounting mechanisms 4 and each buffer assembly 2, and then the connecting sleeve 33 in the lifting and rotating device 3 is pulled to drive the connecting frame 36 and the fan body 8 and other structures to move along the connecting column 31 to the required height, and then the first screw 34 is turned to connect it with the corresponding first threaded hole 32, and then the fan body 8 is rotated to rotate around the connecting shaft 351 in the rotating assembly 35 Rotate to the required direction, and then rotate the second screw 352 to connect it with the second threaded hole 354 on the rotating plate 353 above the connecting shaft 351, and the fixing work is completed; when it is necessary to adjust the position of the fan body 8, turn the knob 62 in the position adjustment device 6, and the knob 62 drives the screw rod 63 to rotate. The screw rod 63 is threadedly connected to the moving block 64, and the outer top surface of the moving block 64 is close to the inner top surface of the fixing box 61, so the screw rod 63 drives the moving block 64 and the mounting plate 7 thereunder to move, thereby adjusting the position of the fan body 8 to better meet the working needs in different situations.
