Limiting and damping fastener
The limiting damping fastener comprises a connecting sleeve, an upper base plate, an elastic base plate and a lower base plate, the upper base plate, the elastic base plate and the lower base plate are sequentially arranged from top to bottom, a limiting protrusion is arranged on the lower surface of the upper base plate, the elastic base plate is provided with an assembly opening, the lower base plate is provided with a limiting opening, and the limiting protrusion penetrates through the assembly opening and extends into the limiting opening. The limiting opening surrounds the outer side of the limiting bulge and is used for clamping and limiting the limiting bulge; the limiting protrusions are arranged on the lower surface of the upper base plate, penetrate through the elastic base plate and are clamped and limited with the limiting openings of the lower base plate, so that the limiting protrusions and the limiting openings can play a limiting role in any direction on the plane where the base plate structure is located; according to the damping fastener, the transverse limiting capacity of an existing damping fastener can be further improved, the longitudinal limiting capacity of the damping fastener is improved, the longitudinal rigidity of a fastener system is improved, and the requirement of a rail system for longitudinal limiting of the fastener can be met.
本发明提供了一种限位减振扣件，包括连接套以及自上至下依次设置的上垫板、弹性垫板、下垫板，上垫板的下表面设置限位凸起，弹性垫板设置装配口，下垫板设置限位口，限位凸起贯穿装配口并延伸至限位口内，限位口环绕在限位凸起的外侧，对限位凸起进行卡接限位；本发明通过在上垫板的下表面设置限位凸起，使得限位凸起贯穿弹性垫板，并与下垫板的限位口卡接限位，使得限位凸起与限位口之间在垫板结构所在平面上的任意一个方向均能够起到限位作用，不仅能够进一步提高现有减振扣件的横向限位能力，而且也提高了减振扣件的纵向限位能力，提升了扣件系统的纵向刚度，能够满足轨道系统对扣件纵向限位的需求。
