Two ends of the limiting rib 81 are respectively provided with a second matching hole 84, and the second matching holes 84 are arranged along the central axis of the limiting rib 81 and are used for being connected with the connecting plate 7 in a threaded manner. After the top cover 6 is disassembled, the second matching holes 84 can be completely exposed, so that the disassembling and assembling sequence is restrained, the assembling accuracy and reliability of the outdoor unit are improved, and the quality consistency of products is good.

The fixing plate 8 is provided with at least one first fitting hole 83 for detachable connection with the top cover 6, such as screw connection, clamping connection, etc. The specific number of the first fitting holes 83 may be set as required, for example, one, two, or three. The fixing plate 8 is further provided with a reinforcing rib 82, and the reinforcing rib 82 is located on one side of the limiting rib 81 far away from the first matching hole 83. This arrangement can improve the mechanical strength of the fixing plate 8 while avoiding interference with the assembly of the top cover 6; the appearance is beautiful and reliable.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the scope or spirit of the present invention, and the scope of the present invention is defined by the appended claims.
