Earthquake-proof distributing board having function reducing vibration in various direction

2016 
Relates to seismic switchgear having a damping function for any direction vibration, the lower anti-vibration module that is inserted between when the bottom surface of the housing 10, 20 has an upper bracket which is fixed to the lower face of the housing 10, 21, When the increasing fixed engaging the lower bracket 22, which is the bottom surface, from the upper and lower surfaces toward the middle of the longitudinal diameter of the upper surface to the binary concave cylindrical shape gradually it gets shorter as being in close contact with the lower surface of the upper bracket 21. the lower bracket (22 ), a small diameter spring 24, the upper bracket 21 and lower bracket in a compressed state is inserted in a compressed state in the interior of the through hole 231 of the elastic body 23, elastic body 23 in close contact with the top surface of the ( 22) the vibration damping effect of any solid direction by including the large diameter spring 25 surrounding the elastic body 23 by being fitted into the groove of the cross, and can complement disadvantages of the disadvantages and anti-vibration spring of the anti-vibration rubber.
