[0005] The reinforcing connector is an "L"-shaped structure, including a first connecting plate connected to the air duct crossbeam and a second connecting plate connected to the air duct body. Two left and right reinforcing ribs are symmetrically arranged between the first connecting plate and the second connecting plate.

[0006] By adopting the above technical solution, the added reinforced connecting piece structure can play a strong supporting role between the air duct body and the air duct crossbeam, making the whole body less likely to deform and having a longer service life.

[0007] Furthermore, the cross-sectional shape of the reinforcing ribs described in the present invention is a rib plate with a triangular structure, and the supporting effect of the double-sided rib plates is better.

[0008] Furthermore, the first connecting plate of the utility model is connected to the air duct crossbeam by bolts, and the second connecting plate is connected to the air duct body by rivets.

[0009] Furthermore, the air duct crossbeam described in the utility model is provided with a strip groove, and the reinforcing connecting piece is embedded in the strip groove through a sliding pad at the bottom.

[0010] Furthermore, bolt holes matching with the reinforcing connector and the sliding pad are equidistantly arranged in the strip-shaped groove of the utility model.

[0011] By adopting the above technical solution, the sliding alignment installation of the reinforced connecting piece in cooperation with the sliding pad in the limiting groove is more convenient and efficient, and can meet the requirements of air duct bodies of different models and structures and different installation positions, which is very practical.

[0012] The beneficial effects of the utility model are as follows: the installation structure of the air duct body of the utility model adopts a new type of beam installation layout, and adds a reinforcement structure to the air duct beam, so that the connection between the air duct body and the air duct beam is more reliable and stable, and the service life is greatly increased, and the number and fixed position of the reinforcement can cope with the installation position and installation quantity of different models of air duct bodies, so that it can be adjusted at any time, and the installation is very convenient.
