Description

A kind of railway Buckle protective lid

Technical field

The utility model relates to a kind of Buckle protective lid, relates in particular to a kind of Buckle protective lid that prevents that the railway fastener is corroded and gets rusty.

Background technology

In order to adapt to development and national economy, the rolling stock speed-raising in the whole nation moves, and the speed-raising of rolling stock proposes higher requirement to the security and stability of rail track, and the security and stability of railway is closely related with the quality of rail fastening again.Yet railway is in operation at present, because rail fastening is open-air because of being exposed to for a long time, through exposing to wind and rain, natural phenomena such as be exposed to the sun very easily produces corrosion, the rail fastening life-span is significantly reduced, thereby bring harm for rail track safety, cause great economic loss.

The utility model content

The purpose of this utility model is to overcome above the deficiencies in the prior art, provides a kind of simple in structure, can effectively protect the protecting cover of railway fastener.

To achieve these goals; the utility model discloses a kind of railway Buckle protective lid; it is characterized in that: over cap is as agent structure; which is provided with the boss of cavity structure; the bottom of boss is communicated with over cap, is fixed with the pintle hook lock of L type on the inwall of over cap, and the two ends fixed seal connection of over cap has water-blocking component; described boss is cylindrical, truncated cone-shaped or right prism shape, can be one-body molded with over cap.

According to such scheme, the beneficial effects of the utility model are: adopt above-mentioned protecting cover to cover fastener, avoid open being corroded outside of fastener to get rusty, improve the safety and the stability of rail track, prolong the application life of fastener, reduce the maintenance work of fastener, save the cost resource of railway construction.
