Rotatory traffic lights of function when holding concurrently note

一种兼记时功能的旋转红绿灯

Abstract

The utility model provides a rotatory traffic lights of function when holding concurrently note, includes the lamp pole and sets up at the inboard light source of lamp pole that the equipartition has four slits on the lamp pole circumference, and the lamp pole outside is encircleed and is provided with the sleeve, and the sleeve can be rotatory for the lamp pole, evenly seted up four group's through -holes on the sleeve, every group through -hole includes threely and is right angled triangle, the through -hole divide into red transparent material through -hole, yellow transparent material through -hole and green transparent material through -hole respectively, and all the other materials are all opaque, the sleeve is an internal diameter and the similar cylinder pipe of lamp pole external diameter, can be rotatory around the lamp pole to it is right angled triangle owing to setting up the through -hole on the sleeve to make four directions show the pilot lamp respectively, so when the sleeve rotated, the light source is constantly changeable through the vertical length of right angled triangle through -hole, and was more and more littleer along with right -angle side length, also signal lamp number second of just explanation demonstration this moment lessens gradually, the utility model has the characteristics of simple structure, low in cost.
一种兼记时功能的旋转红绿灯,包括灯柱以及设置在灯柱内侧的光源,在灯柱圆周上均布有四个狭缝,灯柱外侧环绕设置有套筒,套筒可相对于灯柱旋转;套筒上均匀开设有四组通孔,每组通孔包括三个且为直角三角形;通孔分别分为红色透明材料通孔、黄色透明材料通孔和绿色透明材料通孔,其余材料均不透明;套筒为一内径与灯柱外径相仿的圆柱管,可绕灯柱旋转,从而使四个方向分别显示指示灯,由于套筒上设置通孔为直角三角形,所以当套筒转动时,光源通过直角三角形通孔的竖直长度是不断变化的,随着直角边长度越来越小,也就说明此时显示的信号灯秒数逐渐变少;本实用新型具有结构简单,造价低廉的特点。
