Detailed description of the invention
Below according to drawings and Examples, this utility model is described in further detail.
With reference to Fig. 1-Fig. 6, this utility model, side locking type double-layer vibration damping fastener, including anchor bolt 1, heavy-duty spring packing ring 2, Flat gasket 3, nylon insulating lid 4, upper strata iron chair 5, middle spring bed course 6, lower floor's iron chair 7, insulated buffer plate 8, pedestal 9, nylon sleeve 10, Insulation rail distance keeper 11, rail 12, spring 13, column 71.
This fastener structure is: be embedded with nylon sleeve 10 in pedestal 9, insulated buffer plate 8 is directly layed on pedestal 9, insulated buffer plate 8 is laid lower floor's iron chair 7, middle spring bed course 6 and upper strata iron chair 5 successively, two columns protruded 71 are had on lower floor's iron chair 7, having through hole in the middle of column 71, the bolt hole on this through hole and insulated buffer plate 8 and the through hole on nylon sleeve 10 align；Hole on middle spring bed course 6 that column 71 on lower floor's iron chair 7 passes and upper strata iron chair 5, column 71 height slightly below middle spring bed course 6 and the height sum of upper strata iron chair 5.Nylon insulating lid 4 inserts on column 71 and upper strata iron chair 5 in the gap between hole, Flat gasket 3 is placed on nylon insulating lid 4, heavy-duty spring packing ring 2, anchor bolt 1 is passed down through the bolt hole on heavy-duty spring packing ring 2, Flat gasket 3 and nylon insulating lid 4, running through lower floor's iron chair 7 and screw in nylon sleeve 10, the rail 12 placed in the rail support groove of upper strata iron chair 5 uses spring 13 and Insulation rail distance keeper 11 to fix.
