Abstract
This utility model discloses a snap ring fixing structure, including a grille cover plate. A rectangular frame and two hook-shaped buckles are fixed to the back of the grille cover plate. The two buckles are symmetrically arranged and located inside the rectangular frame. A snap ring is hung on each buckle. A rectangular filter frame is provided inside the rectangular frame. A first strip-shaped through hole is opened on the filter frame corresponding to the positions of the two buckles, allowing the buckle and snap ring to pass through. This exhaust fan housing and snap ring fixing structure uses hook-shaped buckles to engage with the snap ring. Compared with the traditional method of fixing the snap ring with screws, no screwdriver or other tools are needed. When installing the snap ring, it can be directly hung on the buckle, which greatly facilitates the installation operation of the snap ring. Moreover, by allowing the buckle to pass through the first strip-shaped through hole on the filter frame, the edge of the through hole can block the outlet of the buckle, effectively preventing the snap ring from falling off the buckle, further ensuring the stability of the snap ring installation.
