Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown, a kind of shock-absorption fastener system of rail of the invention, including rail 1, the sleeper positioned at 1 lower section of rail
2 and fastener；The fastener includes the pedestal 3 between rail 1 and sleeper 2, and support rod 4 is provided on the pedestal 3, described
The pressing plate 5 parallel with pedestal 3 is provided on support rod 4, the pressing plate 5 is installed on the rail 1, the pressing plate 5
First threaded hole 6, the pedestal 3 are provided with link block 17, and 17 corresponding position of link block offers the second threaded hole 7, institute
It states and is provided with spring 8 in the second threaded hole 7, one first screw 9 passes through first threaded hole 6 and is screwed into the second threaded hole 7.
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
Hollow pipe 14, each pipe 14 are mounted on rubber strip 15, one end of 15 one end of rubber strip connection pipe 14, rubber
The other end of the other end connection pipe 14 of item 15, rubber strip 15 are whole in O-shaped.Rubber strip 15 is arranged to O-shaped, improved slow
Effect is rushed, meanwhile, improve the adjustment amount of rail longitudinal direction.
Further, the lower surface of the pressing plate 5 is provided with arc-shaped convex 16.It is improved by arc-shaped convex 16
Vibration between pressing plate 5 and rail 1 further increases the buffering effect of whole system.
When in use, the first screw 9 passes through first threaded hole 6 and is screwed into the second threaded hole 7 fastener system of the invention
Interior, pressing plate 5 and pedestal 3 is fixed, i.e., fixed rail 1 reduces the movement of rail 1 in the longitudinal direction on sleeper 2, meanwhile, lead to
Spring 8 is crossed, the buffer capacity of the first screw 9 is improved.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
