[0024] A rooftop air handling unit, such as Figure 1 and Figure 2 As shown, it includes a main body 10. Specifically, the main body 10 is formed into a shell structure with a cavity. A fan, a compressor and a controller are installed in the cavity of the main body 10. A heat exchanger is installed on the side wall of the main body 10. The compressor is connected to the controller by electrical signals. The compressor is connected to the heat exchanger through a pipeline. The fan is connected to the controller by electrical signals. An air outlet is provided on the top surface of the main body 10. Air is sucked in and blown to the heat exchanger by the fan. The heated or cooled air is sent into the building from the air outlet to realize air treatment. The specific usage and control method are existing well-known technologies and will not be elaborated here.

[0025] like Figure 2 and Figure 3As shown, a base structure for support is provided at the bottom of the main body 10, and the base structure includes a pad 20, a support body 21 and a pad block 30. Four pads 20 are arranged at the bottom of the main body 10, two pads 20 form a group, a support body 21 is arranged between the two pads 20, and multiple support points are formed between the support body 21 and the two pads 20. The support body 21 can support the pad 20 and extend and deform. The pad block 30 can be detachably installed at the bottom of the pad 20. The pad 20 forms a rectangular plate structure. The two pads 20 in the same group are arranged parallel to each other. The support body 21 forms a metal plate with a wavy cross-section. The bent part of the support body 21 is tangent to the two pads 20 respectively, and the two ends of the support body 21 are respectively tangent to the two pads 20. The walls close to each other are fixedly connected. In this solution, a group of two pads 20 are arranged at the bottom of the main body 10. The two pads 20 in the same group are used to support one side of the bottom of the main body 10. The main body 10 will generate certain vibrations during the opening process. Through the deformation of the support body 21, the support body 21 can be squeezed by the two pads 20 to produce vertical deformation. At the same time, the support body 21 can also extend in the horizontal direction, so that the support body 21 can change the vertical and horizontal vibration frequency of the main body 10 during operation, suppress the resonance of the main body 10 and the pad 20, and reduce the vibration noise generated to the building during the operation of the main body 10, which has better support and protection performance for the main body 10.

[0026] like Figure 3 As shown, the base structure also includes an extension plate 22, and the side walls of the two upper pads 20 are fixedly connected to the same extension plate 22. The wall surface of the extension plate 22 is provided with a mounting hole, and a bolt is provided in the mounting hole. The bolt is threadedly connected to the main body 10. By setting the extension plate 22 and connecting it to the main body 10 with bolts, the pad 20 is installed and fixed, which has the characteristics of easy assembly and disassembly.

[0027] like Figure 4 and Figure 5As shown, the base structure also includes a socket 31 and a plug-in protrusion 32. A plurality of plug-in protrusions 32 are arranged on the top surface of the cushion block 30. A plurality of sockets 31 are correspondingly provided on the wall surface of the pad 20. The plug-in protrusions 32 are plugged into the sockets 31. The plug-in protrusions 32 and the cushion block 30 are integrally formed. The plug-in protrusions 32 form a columnar structure. The plug-in protrusions 32 and the sockets 31 are interference fit. The width of the cushion block 30 is greater than the width of the pad 20. The portion of the cushion block 30 protruding from the pad 20 forms a rib. The portion of the cushion block 30 protruding from the pad 20 is equidistantly provided with a plurality of mounting holes. As a supplement to the above scheme, a rubber pad 30 is provided to form elastic contact between the pad 20 and the roof of the building, thereby suppressing resonance and reducing noise conduction. The detachable pad 30 can be easily replaced and maintained after the pad 30 is aged and damaged. When installing the pad 30, align the plug-in protrusion 32 with the socket 31 and insert it. It is easy to disassemble and assemble, and easy to operate. An installation channel is opened on the wall of the pad 30, and the pad 30 can be fixed to the roof of the building with bolts.

[0028] The working principle of the utility model is as follows: the pad 30 is used to form an elastic contact between the pad 20 and the building roof, so as to suppress resonance and reduce the conduction of noise. The detachable pad 30 can be conveniently replaced and maintained after the pad 30 is aged and damaged. When installing the pad 30, align the plug-in protrusion 32 with the plug-in hole 31 and insert it. The pad 20 is installed and fixed by connecting it with the main body 10 with bolts. A group of two pads 20 are arranged at the bottom of the main body 10. The two pads 20 in the same group are used to support one side of the bottom of the main body 10. The main body 10 will generate a certain vibration during the opening operation. Through the deformation of the support body 21, the support body 21 can be squeezed by the two pads 20 to produce a vertical deformation. At the same time, the support body 21 can also be extended in the horizontal direction, so that the support body 21 can change the vibration frequency of the main body 10 in the vertical and horizontal directions during operation, suppress the resonance of the main body 10 and the pad 20, reduce noise and protect the main body 10 and its internal structure.
