The invention discloses a dimming bolt for a vehicle lamp adjusting device, the dimming bolt is provided with a shoulder part, an annular groove, a step part, a thread part and a smooth part in sequence from top to bottom, by arranging the step part comprising two steps, when the dimming bolt is adjusted towards the direction of a lamp shell, a transmission assembly can more quickly touch the step part to realize limiting of the dimming bolt, and the dimming bolt is more convenient to adjust. The stability of the lamp is ensured; the smooth part with the smooth outer surface is arranged, so that when the dimming bolt is adjusted in the direction far away from the lamp shell, the dimming bolt is prevented from being disengaged, and the stability and safety of the lamp are guaranteed; the axial length of the step portion ranges from 6 cm to 8 cm, preferably 7 cm, the axial length of the smooth portion ranges from 13 cm to 15 cm, preferably 14 cm, the axial length of the threaded portion is maximized under the condition that the bolt can be prevented from slipping off and being excessively adjusted, and the adjustable range of the dimming bolt is guaranteed; according to the device, the dimming bolt is optimized, the structure is simplified, and the manufacturing cost is reduced.

    本发明公开了一种用于车灯调节装置的调光螺栓,调光螺栓从上至下依次设置有肩部、环形凹槽、台阶部、螺纹部和光滑部,通过设置包括两级台阶的台阶部,当向灯壳体方向调节时,传动组件能够更快的触碰到台阶部实现调光螺栓的限位,保证了灯具的稳定性;通过设置外表面光滑的光滑部,当向远离灯壳体的方向调节时,防止了调光螺栓的脱出,保证了灯具的稳定性和安全性;台阶部的轴向长度的范围是6‑8cm,优选7cm,光滑部的轴向长度的范围是13‑15cm,优选14cm,在能够防止螺栓滑脱和过度调节的情况下,将螺纹部的轴向长度最大化,保证了调光螺栓的可调范围;本装置是对调光螺栓自身作出的优化,简化结构,降低制造成本。
