This utility model relates to the field of power fittings technology. It provides an anti-resonance power fitting bowl-shaped mounting plate, comprising a plate surface, an installation cavity fixedly formed inside the top of the plate surface, and a first installation opening fixedly formed at the upper end of the installation cavity; a protective frame, fixedly installed above the first installation opening, with a second installation opening fixedly formed inside the protective frame, and sliding grooves fixedly formed on both sides inside the protective frame. This solves the problem that existing bowl-shaped mounting plates mainly rely on fastener structures for anti-resonance design to reduce damage to power fittings. However, the original anti-resonance structure of the bowl-shaped mounting plate is relatively simple, resulting in poor anti-resonance effect and affecting the service life of the power fittings. When using springs for anti-resonance, the springs lack an effective stabilizing structure, easily generating unstable movement during operation. This instability not only fails to effectively suppress resonance but may also exacerbate the resonance situation or cause other adverse vibration problems.
