right shell are respectively provided with a left screw hole and a right screw hole matched with the flange; The left stud and the right
stud relative to the combination of the left shell and the right shell face symmetric arrangement; The bellows are also provided with two
connecting blocks with a connecting hole, the left shell is provided with a connecting block with the left connecting seat, the right shell is
provided with a connecting block with the right connecting seat. Because the structure of the left stud and the right stud is symmetrical,
the air inlet box and its mirror image can be connected to the left shell and the right shell of the blower, so that the air conditioning box assembly
can be used at the same time in the cab layout on the left side and the cab layout on the right side of the vehicle, which can greatly save the
manufacturing cost; And when installing the bellows, only between the connecting block and the connecting seat, as well as between the stud
stud and the flange in the open position can be stable and fixed into the bellows, installation is more convenient, more efficient.
