Abstract

The invention discloses a fixing bolt for a light rail. The fixing bolt comprises a bolt head, a threaded column, a guiding column, a limiting column and an irregular bolt head, wherein the bolt head,the threaded column, the guiding column, the limiting column and the irregular bolt head are of an integral structure. The fixing bolt disclosed by the invention can be more conveniently mounted; meanwhile, the higher stability can be achieved, and then the running safety of the light rail can be improved; and the promotion and the application can be facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of hardware products, in particular to the technical field of light rail fixing bolts. 【Background technique】 [0002] In recent years, the rapid development of social economy has higher and higher requirements for traffic safety, and the fixed requirements for light rail are also higher and higher. If the track is not fixed firmly, it is easy to tilt or roll over, causing damage to people and goods, thereby seriously reducing the safety and stability of the transportation system. At present, in industrial and mining enterprises such as railways, steel, coal, and mines, most of the light rails used for locomotives are fixed by bolts. The stability and durability of the bolts directly affect the operation of the light rails. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a light rail fixing bolt, which can make the fixing bolt m...
