In this way, the supporting strength of the oil storage cabinet feet can be further improved.

[0028] In the present application, the reinforcing support portion 3 is connected to both fixing plates 1 to ensure the structural strength of the oil storage cabinet legs.

[0029] Specifically, the reinforcing support portion 3 and the two fixing plates 1 are welded into an integral structure to ensure the connection stability between the reinforcing support portion 3 and the fixing plates.

[0030] In the present application, the reinforcing support portion 3 is a reinforcing support plate. When there are multiple reinforcing support plates, the multiple reinforcing support plates are arranged at intervals along the width of the fixed plate 1, and the reinforcing support plate is connected to both fixed plates 1, and the reinforcing support plate is connected to the second support portions 22 of two adjacent support members 2; wherein the thickness direction of the reinforcing support plate is the same as the width direction of the fixed plate 1. Through the above arrangement, the structural strength of the oil storage cabinet foot can be ensured.

[0031] Specifically, the extension direction of each second support portion 22 is arranged at a preset angle with the length direction of the fixing plate 1; wherein the preset angle is 90°.

[0032] Specifically, the second support portion 22 is a second support plate, and the extension direction of the second support portion 22 is the length direction of the second support plate, and the length direction of the second support plate is perpendicular to the length direction of the fixing plate 1 .

[0033] In order to ensure the structural strength of the oil storage cabinet foot, along the width direction of the second support part 22, the second support part 22 includes a first plate section 221, a connecting plate section and a second plate section 222 which are connected in sequence, and the connecting plate section is connected to the first support part 21; along the direction from the first plate section 221 to the second plate section 222, the plate thickness of the first plate section 221 gradually increases, and the plate thickness of the second plate section 222 gradually decreases, and the plate thickness of the connecting plate section is greater than the plate thickness of the first plate section 221 and the second plate section 222.

[0034] Specifically, the width direction of the second support portion 22 is the same as the width direction of the fixing plate 1 .

[0035] Specifically, the minimum plate thickness of the connecting plate segment is greater than the maximum plate thickness of the first plate segment 221 , and the minimum plate thickness of the connecting plate segment is greater than the maximum plate thickness of the second plate segment 222 .
