[0003] A transformer mounting frame with publication number CN111223637A in the prior art mainly includes a fixed frame, a bracket and a movable rod. Fixed sleeves are welded at the four corners of the lower end surface of the fixed frame. The lower end of the fixed sleeve is sleeved on the support rod and fixed by a fixed shaft. Fixed rods are welded on both sides of the lower end of the support rod to enhance stability. A second fixing groove is provided in the middle of both sides of the fixed frame. Both ends of the movable rod are fixed to the fixed frame by screws. A first fixing groove is provided in the middle of the movable rod for installing the transformer. Brackets are movably installed at both ends of the upper end surface of the fixed frame. The brackets are provided with screw holes and a first screw for installing an electric porcelain bottle. However, the mounting frame lacks a flexible adjustment mechanism and is difficult to adapt to transformers of different sizes and weights. The connection method of the fixed shaft and the screws may become loose due to vibration during long-term use, affecting the stability of the mounting frame. Utility Model Content
