Low-height double-layer vibration reduction fastener
The invention relates to a low-height double-layer vibration reduction fastener. The fastener comprises an upper bottom plate, anchoring bolts, elastic strips and an under-rail elastic insulation padand is further provided with a supporting base, a pressing insulation sleeve, a pressing cover plate and an under-plate elastic insulation pad. The fastener is advantaged in that a lower bottom plateof a common fastener is simplified into a bottom supporting seat, so the area and the mass of the lower bottom plate are greatly reduced, cost of the fastener is reduced, moreover, the fastener does not need to be self-locked, so disassembly is very convenient, besides, after the technical scheme is adopted, the pressing force of the fastener is adjustable, the adaptive capacity of the fastener isimproved, and errors caused by fastener machining and manufacturing and long-term operation are conveniently eliminated.
本发明涉及一种低高度的双层减振扣件，该扣件包括上底板、锚固螺栓、弹条及轨下弹性绝缘垫，还设有支撑座、压紧绝缘套、压紧盖板和板下弹性绝缘垫；本发明将普通扣件的下底板简化为底部支撑座，从而大大减少下底板的面积和质量，降低扣件的成本。同时，由于扣件不需自锁，拆卸极其方便。此外，采用上述技术方案后，扣件压紧力可调节，提高了扣件的适应能力，便于消除扣件加工制造和长期运营带来的误差。
