[0025] Referring to Figure 2 and Figure 4 , it is further obtained that the positioning component 4 includes a positioning plate 6 and a pressing plate 7. The pressing plate 7 is movably installed outside the two suspension rods 3. A positioning bolt 8 is connected to the periphery of the suspension rod 3. A stud 9 is fixedly welded to the bottom end of the suspension rod 3. An adjusting rod 10 is movably installed inside the positioning plate 6. Two positioning blocks 11 are connected and installed on the periphery of the adjusting rod 10. First knobs 12 are fixedly installed at both ends of the adjusting rod 10. Fixed sleeves 13 are fixedly installed at both ends of the top of the positioning plate 6. A screw sleeve 14 is movably installed on the top of the fixed sleeve 13. A chuck 15 is installed at the bottom of the screw sleeve 14 and penetrates inside the fixed sleeve 13.

[0026] The aperture at both ends of the inner part of the pressing plate 7 is larger than the cross-sectional diameter of the suspension rod 3. A threaded groove is provided at the top periphery of the suspension rod 3. The positioning bolt 8 is threadedly connected on the periphery of the suspension rod 3.

[0027] The thread directions at both ends of the periphery of the adjusting rod 10 are opposite. The positioning blocks 11 are sleeved on the periphery of the adjusting rod 10 and are threadedly connected.

[0028] The chuck 15 is fixed to the screw sleeve 14. The chuck 15 is rotatably arranged inside the fixed sleeve 13. The screw sleeve 14 is threadedly connected to the stud 9.

[0029] Specifically, the pressing plate 7 slides downward through the connection of the positioning bolt 8 to press the HVAC pipeline. The adjusting rod 10 drives the two positioning blocks 11 to slide to position HVAC pipelines with different diameters, which is applicable to fixing circular or rectangular HVAC pipelines. The screw sleeve 14 is connected to the positioning plate 6 through the chuck 15. The connection between the screw sleeve 14 and the stud 9 facilitates the disassembly and assembly between the positioning plate 6 and the hanging rod 3.

[0030] Embodiment 2

[0031] Refer to Figure 3 and Figure 4 On the basis of Embodiment 1, it is further obtained that the lifting assembly 5 includes two lifting seats 16 and two fixing blocks 17. The two fixing blocks 17 are respectively fixed at the tops of the two hanging rods 3. The two lifting seats 16 are respectively fixed at the bottoms of the two fixing plates 1. A screw rod 18 is movably installed inside the lifting seat 16. A lifting block 19 is connected to the periphery of the screw rod 18. A second knob 20 is fixedly installed at the bottom end of the screw rod 18. A hinge shaft 21 is installed between the fixing block 17 and the lifting block 19.

[0032] The two lifting blocks 19 are symmetrically arranged. The lifting block 19 is sleeved on the periphery of the screw rod 18 and is threadedly connected.

[0033] The lifting block 19 is movably connected to the fixing block 17 through the hinge shaft 21.

[0034] Specifically, the screw rod 18 drives the lifting block 19 to slide up and down, so that the two hanging rods 3 drive the positioning plate 6 and the pressing plate 7 to lift, which is convenient for adjusting the installation support height of the HVAC pipeline. Through the connection of the hinge shaft 21, the individual hanging rod 3 can be adjusted.

[0035] During the actual operation process, the fixing plate 1 is installed or welded to the ceiling by bolts. The HVAC pipeline is located between the positioning plate 6 and the pressing plate 7. The HVAC pipeline is supported and fixed by the hanging rod 3.

[0036] When fixing HVAC pipelines of different specifications, the adjusting rod 10 is rotated by the first knob 12, so that the adjusting rod 10 drives the two positioning blocks 11 to slide and contact the outside of the HVAC pipeline. The pressing plate 7 automatically slides downward under the action of gravity and contacts the outside of the HVAC pipeline. Through the threaded connection between the positioning bolt 8 and the hanging rod 3, the pressing plate 7 presses and fixes the HVAC pipeline, and the positioning block 11 prevents the HVAC pipeline from shifting and sliding. When performing overall disassembly and assembly, a tool is used to rotate the screw sleeve 14, so that the screw sleeve 14 disengages from the stud 9, and then the positioning plate 6 disengages from the hanging rod 3 for disassembly, assembly and maintenance of the HVAC pipeline.

[0037] When adjusting the height of the support and suspension of the HVAC duct, by rotating two second knobs 20, the screw rod 18 drives the lifting block 19 to slide up and down, thereby driving the suspension rod 3 and the positioning plate 6 to follow up and down to adjust the height of the HVAC duct. During the lifting process of the lifting block 19, it is movably connected to the fixed block 17 through the hinge shaft 21, and the individual suspension rod 3 can be adjusted.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
