Transverse limiting and damping fastener
The invention belongs to the technical field of vibration reduction fasteners, and particularly relates to a transverse limiting and damping fastener. The fastener comprises a lower iron base plate, an upper iron base plate, a composite self-locking structure and a transverse limiting structure; and a bolt hole boss is arranged on the lower iron base plate; the upper iron base plate is located on the lower iron base plate, and the upper iron base plate and the lower iron base plate are synchronously fixed through anchor bolts; a damping pad is fixedly mounted on the lower iron base plate; an upper iron retaining shoulder is arranged on the upper iron base plate; a lower iron retaining shoulder is arranged on the lower iron base plate; and a limiting wear-resisting piece is placed on the lower iron retaining shoulder, makes contact with the upper iron retaining shoulder and is extruded by the upper iron retaining shoulder. A composite self-locking structure is adopted, and pre-assembly and disassembly of the fastener and adjustment of the pre-tightening force between the upper iron base plate and the lower iron base plate can be achieved by rotating the self-locking ring at the top of the composite self-locking structure. The damping fastener is good in damping performance and stability and convenient to disassemble and maintain.
本发明属减振扣件技术领域，具体的说是一种横向限位减振扣件，包括下铁垫板和上铁垫板以及复合自锁结构和横向限位结构；所述下铁垫板上设置有螺栓孔凸台；所述上铁垫板位于下铁垫板上，并锚固螺栓同步将上铁垫板和下铁垫板固定；所述下铁垫板上固定安装有减振垫；所述上铁垫板上设置有上铁挡肩；所述下铁垫板上设置有下铁挡肩；所述下铁挡肩上放置有限位耐磨片，且限位耐磨片接触并受到上铁挡肩的挤压；本发明采用了一种复合自锁结构，可以通过旋转复合自锁结构顶部的自锁环实现扣件的预组装、拆卸以及上、下铁垫板之间预紧力的调整。本发明减振性能和稳定性良好，且便于拆卸维修。
