[0018] The utility model will be described in detail in combination with the drawings and examples.

[0019] A sheet metal part, such as Figure 1 and Figure 2As shown, the sheet metal body includes a top plate 1, a connecting plate 2 at both ends of the top plate 1, and a fixing plate 3 fixed on the connecting plate 2, a plurality of mounting holes 301 are formed on the fixing plate 3, and a fixing plate 3 is provided with a fixing plate 1 5 and a fixing plate 2 4 at the bottom, the fixing plate 1 5 and the fixing plate 2 4 are arranged around the bottom of the fixing plate 3 to form a T-shaped clamping groove 6, a plurality of mounting holes 301 are communicated with the clamping groove 6, and a plurality of reinforcing plates 7 are slidably connected in the clamping groove 6. Elastic washers 8 are arranged between adjacent reinforcing plates 7, and a plurality of reinforcing plates 7 are arranged on the fixing plate 3. The mounting holes 301 are connected with external parts, for example, by bolt connection, while the existence of the reinforcing plate 7 improves the overall strength of the sheet metal body when subjected to external force, especially in the case of uneven stress at multiple mounting points. The reinforcing plate 7 can share part of the stress and reduce the possibility of deformation of the mounting hole 301, and the elastic washer 8 provides a buffer between the reinforcing plates 7, reduces vibration and noise transmission during use, and can compensate for the installation error between the reinforcing plates 7 to a certain extent. When the sheet metal body is used for a long time, the mounting hole 301 is broken or enlarged, the elastic washer 8 arranged between the reinforcing plates 7 can reduce the force acting on the reinforcing plates 7 and reduce the damage degree of the perforations 701 on the reinforcing plates 7.
