Description

Technical Field

[0001] This utility model relates to the field of track fastener technology, and in particular to a novel track fastener. Background Technology

[0002] Rail fasteners are fastening devices for rails and sleepers that have elastic clamping components. Rails on a track are connected to each other using clamps and bolts, which is called a rail joint. The wheel-rail dynamic interaction is significant at the joint, resulting in a large workload for maintenance and repair. The joint is one of the weakest links in the rail head structure. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of rail fasteners.

[0003] Existing track fasteners have certain drawbacks. First, they are not convenient and quick to install and position, and their positioning strength does not meet the requirements, which is not conducive to their use. In addition, existing track fasteners may shift during use, affecting their use and causing certain adverse effects on the actual use process. Therefore, we propose a new type of track fastener.
