Embodiment 1

[0012] Referring to the accompanying drawings, a fastener cover for rails, the upper end of the cover is provided with a convex top cover 1, and the lower end of the top cover is extended into an arched protective cover 2, and the top cover is sealed and connected with the protective cover. integrally formed on the substrate. The lower edge of the protective cover is rolled with symmetrical long grooves 4 . The sides of the protective cover extend downwards with side plates 3 of the same shape. The top cover is circular. A hollow protrusion 5 is arranged above the top cover.

[0013] The fastener cover is a new type of rubber and plastic product. The hollow protrusion 5 on the top cover 1 matches and fixes the exposed screw nut. The rainwater drainage groove allows the water to flow away directly from the protective cover without contacting the fastener material, so as to achieve the isolation effect and avoid rusting. The fastener cover can be widely used in the fields of...

Abstract

The buckle protecting cover for railway use has one outwards extruding top cover and one lower arced protecting cover connected together. The protecting cover has symmetrical long slots in the loweredge and two side boards extending downwards. The circular top cover has one hollow raised part in the upper part. Shielding the buckle with the buckle protecting cover can protect the buckle from the erosion of wind ,rain and dirty water for no rust and less maintenance.

Description

(1) Technical field [0001] The invention relates to a fastener protective cover, which is mainly used on exposed fasteners of rails. (2) Background technology [0002] Due to the influence of weather and region, the exposed fasteners on the railway such as screws, nuts, spring backing plates, etc. have been eroded by wind and rain, and are easy to rust, which is a waste of resources; without maintenance for a long time It will affect driving safety; and relying on manual refueling and maintenance is very labor-intensive, time-consuming and labor-intensive, and unsafe. High-speed trains cannot guarantee the safety of maintenance personnel. (3) Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantage that the existing rail fasteners are exposed, and provide a protective cover that can protect the exposed fasteners from being corroded. [0004] For this reason, the present invention takes the following technical solutions: [0...
