After the top cover 6 is disassembled, the second matching hole 84 can be completely exposed, so that the disassembly sequence can be restricted, the assembly accuracy and reliability of the outdoor unit can be improved, and the product quality consistency is good.

The fixing plate 8 is provided with at least one first matching hole 83 for detachable connection with the top cover 6 , such as screw connection, card connection and the like. The specific number of the first matching holes 83 can be set according to needs, for example, one, two, three. The fixing plate 8 is further provided with a reinforcing rib 82 , and the reinforcing rib 82 is located on a side of the limiting rib 81 away from the first matching hole 83 . This setting can improve the mechanical strength of the fixing plate 8 and avoid interference with the assembly of the top cover 6; the appearance is beautiful and reliable.

Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model, so the protection scope of the present utility model should be based on the scope defined in the claims.
