发明名称 EXPLOSIONPROOF FLEXIBLE FIXTURE HANGER
摘要 An explosionproof fixture hanger is disclosed which is adapted to support a depending explosionproof fixture in a manner providing resilient cushioning and lateral flexibility. An annular housing, formed for mounting on a junction box, is fitted with a laterally resilient stem. The stem protrudes through a housing hub and is telescopically carried on a resilient member within the housing for limited axial movement. The inner surface of the housing hub and the outer surface of the stem define a pressure-dissipating explosionproof joint. A lighting fixture is mounted at an opposite end of the resilient stem.
