[0002] Ventilation ducts are an important component for air circulation and exhaust gas discharge inside buildings. They are widely used in residential, commercial buildings, industrial plants and other places. They ensure good indoor air quality, remove harmful gases, and introduce fresh air when necessary. Ventilation duct mounting brackets are important components used to support and fix ventilation ducts to ensure that the ventilation system operates stably and safely in the building. Correct selection and installation of brackets not only helps to maintain the straightness and stability of the duct, but also prolongs its service life and reduces maintenance requirements.

[0003] The existing ventilation duct mounting bracket is fixed to the ceiling by bolts passing through the mounting holes on the mounting bracket and then tightening the bolts, and then hanging down through the hanger or chain on the mounting bracket, and then the ventilation duct is placed at a suitable position between the hanger or chain, and then the bolts are tightened by an external tool to fix the ventilation duct between the hanger or chain to provide stability for the ventilation duct. However, in actual use, when installing and fixing the ventilation duct through the mounting bracket, the personnel need to accurately measure the pipeline path and plan the position and number of the bracket according to the drawings, and then the personnel need to select the mounting bracket of the appropriate specification according to the model and specification of the installed ventilation duct, so that the ventilation duct can match the specification of the mounting bracket to ensure the firmness and stability of the installation. In the use of a large-scale project, a variety of different models of ventilation ducts need to be used, so the personnel need to use mounting brackets of different numbers and specifications to ensure the installation of the ventilation duct, which leads to a chaotic installation process during the planning and installation process due to the need to use mounting brackets of multiple numbers and specifications, and the poor applicability of the mounting bracket brings great trouble to the installation process.
