Shape is coincide, and corresponding diagonal position is equipped with the through-hole 16 passed through for screw spike 8 above and below the two two of which, and makes to lead to
Hole 16 is corresponding with about 14 notch；The outline border constraint iron chair 10 is installed on the top of constraint insulation sleeve 5, and its lubrication groove
The wide outer profile with the cyclic annular spacer ring 15 matches, and support rail iron chair 3 and outline border are constrained iron chair by cyclic annular spacer ring 15
10 isolation；Through-hole 16 and the notch 14 are sequentially passed through after 8 sets of upper gaskets 9 of the screw spike, are screwed on sleeper or railway roadbed
It is in 12 endoporus of service sleeve, resilient sleeper-bearing 4 under outline border constraint iron chair 10, constraint insulation sleeve 5, support rail iron chair 3 and plate is flat
Whole withhold is constraining iron chair 10 and constraint insulation sleeve 5 to constrain support rail iron chair 3 on sleeper or railway roadbed, and by outline border；
Resilient sleeper-bearing 2 under rail is placed in the upper surface of the support rail iron chair 3, steel rail laying 1 on in-orbit lower resilient sleeper-bearing 2；In 1 liang of rail
Mounting rail pulls spring 6 away from pad 7 in the through-hole of support rail iron chair 3 between side and support rail iron chair 3, makes the free end of spring 6
It is pressed on gauge pad 7, is compressed rail 1 on in-orbit lower resilient sleeper-bearing 2 by gauge pad 7.
The upper surface of the support rail iron chair 3 symmetrically has the first toothed surface 19, the constraint insulation sleeve 5 on peripheral four sides
Lower surface there is the second toothed surface 20 corresponding with the first about 19 toothed surface, and second toothed surface 20 is located at the
The top of one toothed surface 19, being coincide by two toothed surface makes constraint insulation sleeve 5 be located on support rail iron chair 3；It is described about
The upper surface of beam insulation sleeve 5 on peripheral four sides symmetrically there is third toothed surface 21, the outline border to constrain 10 following table mask of iron chair
There is the 4th toothed surface 22 corresponding with about 21 third toothed surface, and the 4th toothed surface 22 is located at third toothed surface 21
Top, by two toothed surface coincide make outline border constrain iron chair 10 is located at constraint insulation sleeve 5 on.

On lower face.
The present invention provides elasticity, outline border constraint by resilient sleeper-bearing 4 under resilient sleeper-bearing under rail 2 and plate for entire fastener system
Iron chair 10 be used for by support rail iron chair 3 with resilient sleeper-bearing under plate 4 is smooth withhold together with, constraint insulation sleeve 5 be used for support rail iron
Buffering isolation between backing plate 3 and outline border constraint iron chair 10.
Further, to ensure the damping property of fastener system and withholding effect, constraint insulation sleeve 5 designs tooth four sides
Shape face, the toothed surface that iron chair 10 is constrained with support rail iron chair 3 and outline border coordinate, for limitation and restriction support rail iron chair 3 by
Generated displacement when the horizontal and vertical load arrived, and can by tooth form be oriented to be timely transmitted to outline border constrain iron chair until
Two screw spikes improve the ability that fastener integrally bears horizontal and vertical load.When support rail iron chair is made by vertical wheel rail force
Resilient sleeper-bearing vertically moves under used time naturally downward compression plate, and passes through resilient sleeper-bearing absorption under plate, decaying vibrational energy；When holding
Rail iron chair can run through tooth form guiding and load is transferred to outline border constraint iron chair when being acted on by wheel-rail lateral force, and final
It is all transferred on sleeper or railway roadbed by screw spike.
The constraint insulation sleeve 5 devises the cyclic annular spacer ring with plane perpendicular, by support rail iron chair 3 and outline border about fagot pad
Plate 10 is isolated, and when support rail iron chair 3 is by vertical load, which is used to provide hanging down for support rail iron chair with toothed surface
Straight displacement is oriented to, and load and vibration are transferred to resilient sleeper-bearing 4 under outline border constraint iron chair 10 and plate.When support rail iron chair by
When the multi-direction load of wheel track acts on simultaneously, support rail iron chair can be in time in the case where outline border constrains iron chair and the constraint for constraining insulation sleeve
It is oriented to, converting most of load to vertical force transmits, and can prevent constraint from insulating to greatest extent especially by tooth form guiding
Warpage, torsional displacement occur for set, ensure that constraint insulation sleeve is in normal operating conditions always.
Further, the mounting height basic one of the constraint insulation sleeve 5 and support rail iron chair 3 and outline border constraint iron chair 10
It causes, the length of screw spike 8 is relatively short, and fastening effect is good, is not likely to produce loosening, and the moment of flexure that fastener is integrally born is smaller.
Above-described embodiment, only presently preferred embodiments of the present invention, is not used for limiting the scope of the present invention, therefore all with this
The equivalent variations that content is done described in invention claim should all be included within scope of the invention as claimed.
