[0046] The lower back plate 3 of the embodiment bears the weight of the pressure regulator and the building pressure regulating box body 100. After the first reinforcing structure and the second reinforcing structure are provided, the bending resistance of the rear back plate is enhanced. Therefore, the material used for the upper back plate 2 can be thinned, and the material used for the lower back plate 3 under the same installation condition can also be thinned. The design of the upper back plate 2 and the lower back plate 3 in the embodiment avoids the problem of generating edge waste in the prior art in which an independent metal plate is welded as a support part of the rear back plate. The reliable support is provided for the rear back plate without using additional plates, the material waste is reduced, and the production cost is lowered.

[0047] The support part on the rear back plate of the conventional box body is usually fixed by welding. First, an additional plate is needed as the support part.

In the welding process, the welding parameters need to be strictly controlled to ensure the welding quality. After welding, the welding part needs to be polished, rust-proofed, and treated. These processes not only increase the complexity and time cost of production, reduce the production efficiency, but also may cause welding deformation and other problems in the welding process, affecting the overall size accuracy and appearance quality of the box body. Additional correction processes are needed to solve the problems. The first back plate 6, the second back plate 7, and the third back plate 8 of the embodiment are completed by die stamping or cutting before bending. The shape and position of the holes of the parts have high machining precision, the positioning is accurate after bending, and the assembly is convenient. The embodiment does not need positioning, welding parameter control, post-welding treatment, and other complex processes, avoids welding deformation and other problems, provides a reliable support structure for the rear back plate without using additional plates, simplifies the installation process of the rear back plate support part, reduces the processes, improves the production efficiency and product quality.

[0048] The embodiment optimizes the box structure, and three supporting points arranged in a triangular shape are formed on the lower back plate 3. During the assembly process, the three supporting points ensure the parallelism of the inlet and outlet axes of the pressure regulator and the lower back plate 3, and prevent the pressure regulator from being inclined.

[0049] In the embodiment, the first recess 19 is punched on the first back plate 6, the first box frame recess 20 and the second box frame recess are punched on the box frame 1, and the second recess is punched on the third back plate 8, which plays a good positioning role during the assembly process, and makes the assembly process more smooth. The assembly personnel can more quickly and accurately assemble the building pressure regulating box body 100, reduce the assembly difficulty and workload, and improve the assembly efficiency.
