Preferably, described spring is one-body molded.
Preferably, backing plate, plate are finely tuned under described backing plate assemblies includes railway rail pad, plastic base, insulated buffer plate, rail
Lower height adjusting cushion plate, finely tunes under backing plate, plastic base, plate height adjusting cushion plate and insulated buffer plate successively under described railway rail pad, rail
It is stacked at described rail base.
Preferably, described fixation kit includes screw spike, lock washer, Insulation rail distance keeper and plastic bushing, described in mould
Material sleeve pipe is embedded in the ground bottom described insulated buffer plate, has female thread inside it, and described lock washer coordinates institute
State screw spike to sequentially pass through height adjusting cushion plate under plate described in described U-shaped body, plastic base and be spirally connected with described plastic bushing.
Preferably, described spring is withheld in described top of the rail away from the side of described U-shaped body open end.
Preferably, described plastic base includes that finely tuning backing plate under accepting groove, described rail base and railway rail pad and rail depends on
Secondary it is contained in described accepting groove.
Preferably, the medial wall of described accepting groove and described is located in described accepting groove and is located in described Insulation rail distance keeper
Finely tune under rail base, railway rail pad, rail between the sidewall of backing plate.
Preferably, described railway rail pad is rubber mat plate or compound backing plate.
The beneficial effects of the present invention is: the tramcar fastener construction that the present invention provides is simple, rail can be made to keep long
Long, stable gauge and rail are high, decrease potential safety hazard when tramcar travels.
[accompanying drawing explanation]
