Description

Technical Field

[0001] The utility model relates to the technical field of installation of an air-conditioning return air static pressure box, in particular to an installation and fixing structure of an air-conditioning return air static pressure box. Background Art

[0002] The traditional installation and fixation of the air-conditioning return air static pressure box only considers whether the lifting is stable and reliable, but often ignores whether the internal structure of the air-conditioning return air static pressure box is stably and reliably supported during the installation process. Therefore, the traditional solution usually leads to problems such as the sound-absorbing material falling off and air leakage caused by ventilation in the air-conditioning return air static pressure box. In severe cases, the structure of the air-conditioning return air static pressure box will be deformed and damaged, which reduces its service life and increases maintenance costs.
