[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: an outdoor unit of a variable-frequency multi-connected air-conditioning system, including an outdoor unit body 1, an installation groove 13 is opened at the rear side of the outdoor unit body 1, a plurality of first inspection openings are opened in the installation groove 13, a maintenance housing 2 is installed in the installation groove 13, a plurality of second inspection openings 7 are opened in the maintenance housing 2, the second inspection openings 7 correspond to the first inspection openings, a sliding frame 10 is installed in the second inspection openings 7, a door panel 12 is slidably matched in the sliding frame 10, a fixed support base 3 is installed on the lower side of the outdoor unit body 1, and a plurality of auxiliary support bases 4 are installed on the lower side of the fixed support base 3.
[0022] In this embodiment, the outdoor unit body 1 and the fixed support base 3 are of an integral structure, the fixed support base 3 and the auxiliary support base 4 are fixedly connected by bolts, a plurality of support rods 6 are fixed in both the fixed support base 3 and the auxiliary support base 4, adjacent two support rods 6 are in contact with each other, and a plurality of air dispersion openings 5 are opened on the circumferences of the fixed support base 3 and the auxiliary support base 4.
[0023] Specifically, an appropriate number of auxiliary support bases 4 can be selected according to needs, the auxiliary support bases 4 are fixedly connected to each other by bolts, and then the auxiliary support bases 4 and the fixed support base 3 are fixedly connected by bolts, so as to raise the outdoor unit body 1 to the required height. The number of auxiliary support bases 4 at the bottoms of multiple outdoor unit bodies 1 is different, so that the heights of multiple outdoor unit bodies 1 can be controlled to be different, thereby staggering multiple outdoor unit bodies 1 and ensuring the ventilation effect.
[0024] The four corners of the maintenance housing 2 are fixedly installed in the installation groove 13 by bolts. A first limiting plate 8 and a second limiting plate 9 are fixed in the second inspection opening 7. The sliding frame 10 is located between the first limiting plate 8 and the second limiting plate 9.
