For coordinating the screw spike of described railway spike installing hole and described nylon sleeve, described screw spike is provided with nut, and the below of described nut is provided with Type B spring;
Be arranged at resilient sleeper-bearing under the rail between grooved rail and described installation backing plate, under described rail, between resilient sleeper-bearing and described installation backing plate, rail be also set and lower high backing plate.
As the improvement of technique scheme, between the described nut of described screw spike and described Type B spring, be also provided with elasticity lock washer.
As the improvement of technique scheme, be positioned at described railway spike position of mounting hole place and be provided with the mounting groove coaxial with described railway spike installing hole bottom described installation backing plate, the upper end of described nylon sleeve is positioned at described mounting groove.
As the improvement of technique scheme, described installation backing plate two ends are provided with spacing reinforcing rib, Insulation rail distance keeper is provided with between described spacing reinforcing rib and grooved rail, described Insulation rail distance keeper section is " 7 " font and comprises horizontal part and vertical portion, the horizontal position of described Insulation rail distance keeper is between described Type B spring and grooved rail, and the vertical portion of described Insulation rail distance keeper is between described spacing reinforcing rib and grooved rail.
As the improvement of technique scheme, be also provided with spring seat height adjusting cushion block between described Type B spring and described installation backing plate, described spacing reinforcing rib is provided with cushion block stopper slot, and described spring seat height adjusting cushion block is provided with the tenon coordinating described cushion block stopper slot.
Compared with prior art, implementation result of the present invention is as follows in the present invention:
A kind of flush type tram fastener of the present invention, adopt elasticity regardless of open architecture, namely grooved rail is directly coupled together by screw spike and basis, does not have iron chair in system, greatly reduces the cost of production of fastener; Simultaneously a kind of flush type tram fastener of the present invention can first and grooved rail assemble, more directly build integrally railway roadbed, eliminate production and the laying operation of sleeper, greatly reduce cost and the difficulty of track construction.Present invention employs the spring seat height adjusting cushion block of innovative design in addition, 20 millimeters of amounts of heightening greatly that general elasticity separated rail fastening is difficult to realize can be realized, expand the compliance of fastener in different location.
