VIBRATION ISOLATION DEVICE FOR ELECTRICAL EQUIPMENT USE

摘要

PROBLEM TO BE SOLVED: To provide a vibration isolation device for electrical equipment use, which is simple in structure and can limit vibrations, which are applied to a rubber vibration insulator at the time of transportation of the device. SOLUTION: A base 3 is laid under a base fitment 2 of an electrical equipment main body 1 and is arranged. A stud bolt 5 is laid in such a way as to correspond to a base hole 14 formed in the fitment 2 and is vertically provided over the base 3. The bolt 5 is laid on a locking nut 6 and is fixed on the base 3 via the nut 6. The point of the bolt 5 is inserted in the hole 4. An annular rubber vibration insulator 7 is arranged on the outer periphery of the bolt 5 between the laid base 3 and the fitment 2. A nut 9 is screwed onto the part of the bolt 5 made to penetrate by the fitment. The height of the nut 6 is set in a height which limits a compression of the rubber vibration insulator 7 within the limitation of the elasticity of this rubber vibration insulator 7.
