Telescopic component of universal wheels of mobile traffic signal lamp

Abstract

The invention provides a telescopic component of universal wheels of a mobile traffic signal lamp. The telescopic component comprises a mounting box (100), a signal lamp set (200) fixedly arranged above the mounting box (100), and universal wheels (300), wherein the universal wheels (300) are set to be in an extending state and a retracting state which can be mutually switched, the universal wheels (300) in the extending state extend to the lower part of the mounting box (100), the universal wheels (300) in the retracting state retract into the mounting box (100), the universal wheels (300) inthe extending state are suitable for mobile transportation, the mounting box (100) is further internally provided with a telescopic mechanism (310) and a power driving device (500), the telescopic mechanism (310) is used for controlling the universal wheels (300) to be switched between the extending state and the retracting state, and the power driving device (500) is used for providing driving power for the telescopic mechanism (310). In the using process, the universal wheels (300) are retracted into the mounting box (100), so that the bottom surface of the mounting box (100) is enabled tobe in direct contact with the ground, and the situation that stable placement cannot be achieved due to rolling of the universal wheels (300) is avoided.

Description

technical field [0001] The invention relates to a traffic signal lamp, in particular to a telescopic component of a universal wheel of a mobile traffic signal lamp. Background technique [0002] Traffic lights are an important tool to strengthen road traffic management, reduce traffic accidents, improve road use efficiency, and improve traffic conditions. Traffic lights are divided into fixed traffic lights and mobile traffic lights. Mobile traffic lights are mainly used for At the intersection where the fixed traffic signal lights cannot work normally, specifically, when the fixed traffic signal lights are damaged and cannot be used normally or when the fixed traffic signal lights are powered off and cannot be used normally, it can be used as a temporary replacement for the fixed traffic signal lights. The existing mobile traffic lights mainly include an installation box, a signal light group erected on the installation box, and universal wheels located under the installati...

[0002] Traffic lights are an important tool to strengthen road traffic management, reduce traffic accidents, improve road use efficiency, and improve traffic conditions. Traffic lights are divided into fixed traffic lights and mobile traffic lights. Mobile traffic lights are mainly used for At the intersection where the fixed traffic signal lights cannot work normally, specifically, when the fixed traffic signal lights are damaged and cannot be used normally or when the fixed traffic signal lights are powered off and cannot be used normally, it can be used as a temporary replacement for the fixed traffic signal lights. The existing mobile traffic lights mainly include an installation box, a signal light group erected on the installation box, and universal wheels located under the installation box. The disadvantage is that although the universal wheels can facilitate its movement and transportation, the universal wheels are easy to cause It cannot be placed stably, especially when used on sloped roads or in windy weather. In addition, the vibration caused when the heavy truck passes the road can easily cause the rolling deflection of the universal wheels. In order to overcome the above-mentioned shortcomings, it is necessary for the present invention to provide a The telescopic member of the universal wheel of the mobile traffic signal light with ingenious structure and simple principle, which can retract the universal wheel
