Description
Technical field
The application relates to, but are not limited to field of track traffic, especially a kind of flexible clamp piece.
Background technology
In recent years, the fast development of Rail Transit System, is that the production and living of people bring huge facility, and and this
Meanwhile, the production and living that vibration that these modes of transportation are brought, noise pollution also give people bring very big puzzlement.In order to solve
This problem, in the market is proposed multiple product, wherein detachable double-layer vibration damping fastener because its superior damping property, rationally
Cost widely applied.
The key technology of detachable double-layer vibration damping fastener is the connected mode between iron plate and lower iron plate, current city
Mainstream technology on field is that cannular boss is set on lower iron plate, and is set on the upper iron plate corresponding with correspondence cannular boss position
There is circular hole, in the circular hole of the upper iron plate of cannular boss insertion for assembling iron plate at present, while using connection member to be embedded in lower iron plate
In the gap that cannular boss and the circular hole of upper iron plate are constituted, the level connection joint for upper iron plate and lower iron plate is formed；Finally will
The nylon sleeve that the anchor bolt of cover plate is screwed on sleeper through cannular boss is cased with, the connection for overall fastener is realized.
During realizing above-mentioned functions, embedded lower connection member between the cannular boss of iron plate and the circular hole of upper iron plate is particularly weighed
Will, it is the critical component for realizing iron plate and the positioning of lower iron plate and other critical functions on fastener.
A kind of connection member is refer in document disclosed in prior art, be nested in iron plate hole and lower iron plate it is hollow
In the gap that boss is constituted；Dead bolt is arranged below in connection member, and top carries flange, by the way that connection member is nested in into cooperation
