Novel bolt-free fastener
The novel bolt-free fastener comprises a steel rail arranged on a sleeper, bolt-free buckling and pressing structures for fixing the steel rail to the sleeper are symmetrically arranged on the left side and the right side of the steel rail, each bolt-free buckling and pressing structure comprises an embedded iron base, an elastic strip and an installation sleeve, a positioning groove is formed in the part, on the sleeper, of the embedded iron seat, and the positioning groove is arranged in the horizontal direction; the mounting sleeve is horizontally mounted in the positioning groove and is clamped and matched with the positioning groove; the elastic strip is of an omega-shaped symmetrical structure and is provided with a middle arc and a tail part, the tail part is reversely bent towards the middle part, the tail part of the elastic strip is inserted into the mounting sleeve through the opening of the mounting sleeve, and the middle arc of the elastic strip is used for pressing the steel rail. Components of the bolt-free fastener completely abandon the design form of an existing fastener, mounting and dismounting are more convenient, later line maintenance is more convenient, and the problem that maintenance and replacement are difficult due to rust or collision of the threaded part of the bolt is avoided.
本发明公开了一种新型无螺栓扣件，包括布置在轨枕上的钢轨，钢轨的左右两侧对称布置有将钢轨固定在轨枕的无螺栓扣压结构，无螺栓扣压结构包括预埋铁座、弹条和安装套，其中：预埋铁座预埋固定在轨枕中，预埋铁座在轨枕上的部分设有定位槽，定位槽为水平方向布置；安装套水平安装在定位槽内，并与其卡接配合；弹条为呈Ω形的对称结构，具有中部圆弧和尾部，尾部向中部反向折弯，弹条的尾部由安装套的开口插在安装套中，弹条的中部圆弧用于压紧钢轨。本发明无螺栓扣件的部件组成完全摒弃了现有扣件的设计形式，安装拆卸更方便，更加方便后期线路维修，避免了因螺栓螺纹部分锈死或磕碰造成维修更换困难。
