Abstract

一种枕木道轨固定螺丝,它是由螺帽、螺套和螺纹组成的,其中六棱柱形的螺帽和圆柱形螺套是一体的,螺纹是在螺帽中加工而成的,用于固定到铁道的枕木丝杆上,螺纹的长度小于螺帽的高度。安装时,先将一些防锈油挤入螺帽内,进行固定,固定后,枕木道轨固定螺丝的螺帽将枕木丝杆、弹簧垫片和垫片一起密封起来,使外界雨水、酸、碱、油无法腐蚀螺纹,可保持丝杆强度不变。

Description

枕木道轨固定螺丝
本实用新型提供一种枕木道轨固定螺丝,属铁路道轨的固定连接件领域。
目前,使用的枕木道轨固定螺丝由于其结构特点,密封性不好,抗锈差,每年需要防锈保养一次,浪费了大量人力、物力,而且还威胁铁路运输的安全。
本实用新型针对现有枕术道轨固定螺丝的缺点,提供一种结构简单,加工方便,不易锈蚀,耐用的枕木道轨固定螺丝。
本实用新型是由螺帽、螺套和螺纹组成的,其中六棱柱形的螺帽和圆柱形螺套是一体的,螺纹是在螺帽中加工而成的,用于固定到铁道的枕木丝杆上,螺纹的长度小于螺帽的高度。安装时,先将一些防锈油挤入螺帽内,进行固定,固定后,枕木道轨固定螺丝的螺帽将枕木丝杆、弹簧垫片和垫片一起密封起来,使外界雨水、酸、碱、油无法腐蚀螺纹,可保持丝杆强度不变。
本实用新型的优点:结构简单、加工方便、耐锈蚀。
附图说明:
图1为本实用新型的剖面图
结合说明书附图对本实用新型进行详细说明:
本实用新型是由螺帽2、螺套1和螺纹3组成的,其中六棱柱形的螺帽2和圆柱形螺套1是一体的,螺纹3是在螺帽2中加工而成的,用于固定到铁道的枕木丝杆上,螺纹3的长度小于螺帽2的高度。安装时,先将一些防锈油挤入螺帽2内,进行固定,固定后,枕木道轨固定螺丝的螺帽2将枕木丝杆、弹簧垫片和垫片一起密封起来,使外界雨水、酸、碱、油无法腐蚀螺纹3,可保持丝杆强度不变。
