Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
As shown, a kind of shock-absorption fastener system of rail of the utility model, including rail 1, positioned at 1 lower section of rail
Sleeper 2 and fastener；The fastener includes the pedestal 3 between rail 1 and sleeper 2, is provided with support rod 4 on the pedestal 3,
The pressing plate 5 parallel with pedestal 3 is provided on the support rod 4, the pressing plate 5 opens up on the rail 1, the pressing plate 5
It is equipped with the first threaded hole 6, the pedestal 3 is provided with link block 17, and 17 corresponding position of link block offers the second threaded hole
7, spring 8 is provided in second threaded hole 7, one first screw 9 passes through first threaded hole 6 and is screwed into the second threaded hole 7
It is interior.
Further, third threaded hole 10 is offered on the support rod 4, one second screw 11 passes through the third spiral shell
Pit 10 is arranged with spring ring 12 outside the rail 1, second screw 11, and the diameter of the spring ring 12 is greater than third
The diameter of threaded hole 10.By the fixed rail 1 of the second screw 11, the lateral movement of rail 1 is reduced, meanwhile, by spring ring 12,
The buffering of rail 1 horizontally is improved, the impact of rail 1 is reduced, prevents whole loosening.
Further, the bottom of second screw 11 is provided with rubber layer (not shown).The is reduced by rubber layer
Damage of two screws 11 to rail 1.
Further, 1 bottom of rail is provided with buffer unit.Rail 1 is buffered by buffer unit, is had
There is good buffering effect.
Specifically, the buffer unit includes being connected with sleeper 2 including the pedestal 3, and the pedestal 3 is provided with multiple
