Rail traffic signal lamp easy to maintain

Abstract

The invention discloses a rail traffic signal lamp easy to maintain. The rail traffic signal lamp comprises a box, a first bearing is clamped to the lower surface of the inner wall of the box, a firstrotary shaft is sleeved with the inner surface of the first bearing, the top of the first rotary shaft is fixedly connected with the bottom of a threaded column, the top of the threaded column is fixedly connected with the bottom of a rotary device, and the rotary device is clamped to the upper surface of the inner wall of the box. The surface of the threaded column is in threaded connection witha thread cap, and the thread cap is clamped to the upper surface of a first movable plate. According to the rail traffic signal lamp easy to maintain, through mutual cooperation of the first rotary shaft, a first bevel gear, a second bevel gear, a second rotary shaft, a handle, a connecting plate, the threaded column, the thread cap, a sliding rod, a sliding sleeve and signal lamp bodies, it is not required that a worker climbs up an iron pole by using an another object to maintain the signal lamp bodies, the life safety of the worker is ensured, and moreover, convenience is brought to the work of the worker.

Description

technical field [0001] The invention relates to the technical field of signal lamps, in particular to a rail traffic signal lamp which is convenient for maintenance. Background technique [0002] Road traffic signal lights are a category of traffic safety products. They are an important tool to strengthen road traffic management, reduce traffic accidents, improve road use efficiency, and improve traffic conditions. Applicable to intersections such as crosses and T-shaped intersections, it is controlled by road traffic signal controllers to guide vehicles and pedestrians to pass safely and orderly. LED (Light Emitting Diode) is a new type of light source developed and produced in recent years. It has low power consumption (current is only 10~20mA), high brightness (light intensity can reach tens of thousands of mcd), and small size (the minimum diameter can reach 3mm) , light weight (a light-emitting diode weighs only a few tenths of a gram), long life (average life of 100,0...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a rail traffic signal light that is easy to maintain, which solves the problem that the staff can maintain the traffic signal light. Usually, the staff use foreign objects to climb the iron pole to maintain the traffic signal light. The danger not only brings inconvenience to the work of the staff, but also poses a threat to the life of the staff
