Be provided with multi-disc steel disc and multi-disc sheet rubber, be provided with the middle part of the shock mount in mounting hole and the mounting hole be equipped with it is logical
Silk suspension rod, the harness cord boom foot is provided with nut.
Preferably, the main joist with the false keel is perpendicular is interspersed so that main joist and false keel stress
Uniformly.
Preferably, the main joist is c-type keel, main joist is convenient using vertical arrangement, can make its longitudinal direction by
Power will not be deformed.
Preferably, the thickness of the sheet rubber is equal to the thickness of twice of steel disc, sheet rubber has stress and deformation function, can
To reach buffering and damping effect, steel disc is spaced apart successively with sheet rubber, and steel disc is on-deformable, and steel disc causes rubber
Piece surface uniform force.
Preferably, the sheath is pvc sheath, pvc sheath has anti-aging function, and extension uses the longevity
Life.
The beneficial effects of the utility model are：The false keel of setting is in hollow and internal filled with acoustical cotton layer and secondary
Keel both sides are evenly equipped with through hole, and sound is entered inside false keel from through hole can just be absorbed by acoustical cotton layer, reach sound-absorbing
Function；Multi-disc steel disc and multi-disc sheet rubber are sequentially arranged at intervals with the sheath of the shock mount of setting, with damping effect；If
U-shaped kink and main joist clamping are provided with the top of the connector put and connector two bottom sides are provided with the hook bent inwards
With false keel clamping, main joist and false keel are attached using clamping component so that installation and removal are convenient；The harness cord of setting
It is arranged at the top of suspension rod in floor, bottom can adjust the horizontal level and height of whole ceiling joist by rotating nut.
