To achieve these goals, the utility model has been taked following technical scheme.Mainly include dowel bar 1, displacement type power consumption material block 2, retainer plate 3, turning collar 4, force transmitting board 5, support bar 6 with fixedly connected first being connected hinged-support 7 and being connected hinged-support 8 of element of installation or building with second.Wherein, retainer plate 3 is arranged on the outside of turning collar 4 and with second to be connected hinged-support 8 fixedly connected, is fixed with displacement type power consumption material block 2 at retainer plate 3 and turning collar 4 contacts site; It is hinged that one end of dowel bar 1 and first is connected hinged-support 7, and the other end and first connecting axle 9 are hinged, and first connecting axle 9 is fixedlyed connected with force transmitting board 5, and force transmitting board 5 is fixedlyed connected with turning collar 4; It is hinged that one end of support bar 6 and second is connected bearing 8, and the other end is fixedlyed connected with second connecting axle 10, and second connecting axle 10 passes the center of the turning collar 4 that is positioned on the force transmitting board 5, and turning collar 4 can rotate around second connecting axle 10.
Be pasted with displacement type power consumption material block 2 at retainer plate 3 and turning collar 4 contacted surfaces.
Be provided with groove at retainer plate 3 and turning collar 4 contacted positions, displacement type power consumption material block 2 is arranged in this groove.
Described displacement type consumption material can piece 2 be lead or mild steel or the power consumption piece made by macromolecular material.
Distance between first 9 and second 10 is 2～5 with the span of the ratio of retainer plate 3 inner surface radiuses.This ratio value is big more, and the displacement after the amplification is big more.According to the character of the power consumption needs of equipment or building and power consumption material, determine the size of this ratio.
The utility model can amplify the relatively little displacement between the different structure member or the corner the best power consumption displacement request according to the power consumption material, promptly with fixedly connected first being connected hinged-support 7 and being connected little displacement that hinged-support 8 bar structures produce or corner with second and being delivered to turning collar 4 of equipment or building by first 9, force transmitting board 5 and second 10, relative displacement between turning collar 4 and the retainer plate 3 is amplified, thereby make displacement type power consumption piece consume maximum energy, and then the wind that reduces the vibration of equipment or building structure shake reaction and earthquake response.The utlity model has advantages such as volume is little, stable, manufacturing is simple, easy to maintenance, good endurance, is a kind of device of passive energy dissipation very efficiently.
