Detailed description of the invention
Below according to drawings and Examples, this utility model is described in further detail.
nullWith reference to Fig. 1-Fig. 7，This utility model，Pedestal 1 is embedded with nylon sleeve 17，Insulated buffer plate 2 is directly layed on pedestal 1，Insulated buffer plate 2 is laid ferrum connecting rod 16 successively、Elastic insert 3 and upper strata iron chair 4，Ferrum connecting rod 16 is installed insulation gland 15 and pressing plate 14，Height is slightly below the height sum of elastic insert 3 and upper strata iron chair 4，When anchor bolt 12 is passed down through heavy-duty spring packing ring 13、Bolt hole on pressing plate 14 and insulation gland 15 runs through ferrum connecting rod 16，When screwing in the nylon sleeve 17 being fixed on pedestal 1，The height space formed by ferrum connecting rod 16 column 19 and nylon insulating lid can at the fixing elastic insert 3 of short transverse and upper strata iron chair 4，And elastic insert 3 is formed the compression of 0.5～1mm，Guarantee that middle spring bed course 3 is while fully contacting with upper strata iron chair 4，Can be played it completely elastic.
