Title:
MOUNTING METHOD FOR FRESH AIR VENTILATION UNIT
Document Type and Number:
WIPO Patent Application WO/2022/047825
Kind Code:
A1
Abstract:
A mounting method for a fresh air ventilation unit, which comprises the following steps: S1: taking a main unit out from within a box body, and preparing a material to receive a main unit power source wire from a switch box; S2: fixing a fixed plate (1) on a wall body; subsequently, placing the main unit into a fixing mesh box (3), and fixing the main unit by means of a moving clamp mechanism (4) arranged within the fixing mesh box (3) which can clamp and fix the main unit; S3: when it is necessary for the moving clamp mechanism (4) to clamp the main unit, controlling a drive motor (45) to rotate by means of a control button, the drive motor (45) drives threaded rod slide sleeves (42) to rotate by means of bidirectional helical threaded rods (41), the threaded rod slide sleeves (42) impel symmetrically arranged mesh clamp plates (44) within the fixing mesh box (3) to move toward each other, and said movement of the mesh clamp plates (44) can clamp and fix the main unit. The present invention facilitates clamping and fixing work on the main unit, and prevents the main unit from shaking when installed in the mesh box.
