Pilot pin, the pilot pin can pass through the through hole, fixed first nut and second nut.
Specifically, the rail fixing bolt is screwing the first nut by the setting of the first threaded portion and the second threaded portion And second in the case of nut, nut can be avoided to free loosening, be further advanced by positioning to the fixed effect of railway more preferably The further nut of clamping first of setting of pin and the second nut prevent the loosening of rail anchor bolt nut.
Preferably, the pilot pin is 7 fonts, and the vertical portion of 7 font can pass through the through hole.
Preferably, in addition to magnetic emits, and the interior edge that the magnetic emits is provided with screw thread, the direction of the screw thread and the magnetic The internal diameter that property emits is engaged in second threaded rod.
Preferably, the magnetic emit bottom set it is fluted, the shape of the groove is in the shape of the 7 font horizontal part It is engaged.
Preferably, in addition to packing ring, the packing ring are sheathed on second threaded rod, positioned at first nut and described Between second nut.
Preferably, the packing ring is at least one of anistree pad, spirotallic gasket and wave tooth spacer.
The beneficial effects of the present invention are:The rail fixing bolt by the setting of the first threaded portion and the second threaded portion, In the case where screwing the first nut and the second nut, nut can be avoided to free loosening, entered to the fixed effect of railway more preferably The loosening of rail anchor bolt nut is prevented to one step by the further nut of clamping first of setting of pilot pin and the second nut.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
Brief description of the drawings
Exemplary embodiment of the invention is described in more detail in conjunction with the accompanying drawings, it is of the invention above-mentioned and its Its purpose, feature and advantage will be apparent, wherein, in exemplary embodiment of the invention, identical reference number Typically represent same parts.
