Liftable signal lamp with locking function

Abstract

The invention discloses a liftable signal lamp with a locking function. The liftable signal lamp is characterized in that the upper end of a support rod sleeves the middle of a drive shaft, the lowerend of the support rod is fixedly connected with a bottom plate, the upper end of the bottom plate is rotatably connected with the lower end of a threaded rod through a bearing, a sleeve is connectedto the upper portion of the threaded rod in a threaded manner, a transverse plate is fixedly connected to the upper portion of the sleeve, a second bevel gear is fixedly connected to the lower portionof the threaded rod and meshes with a first bevel gear, the first bevel gear is fixedly connected with the drive shaft, and telescopic rods are arranged on two sides of the drive shaft. The liftablesignal lamp has the advantages that a bidirectional screw rotates to drive slide rods to move leftwards and rightwards to drive insertion rods to move leftwards and rightwards, the insertion rods areinserted into the peripheral insertion holes of wheels to lock the wheels, green energy such as solar energy and wind energy is used as the energy of the signal lamp, and the signal lamp is capable ofsaving energy, environmentally friendly, free of pollution, beneficial to sustainable development, reasonable and applicable in structural design, capable of saving electric energy and harmless.

Description

technical field [0001] The invention relates to a traffic auxiliary device, in particular to a lifting signal lamp with a locking function. 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. [0003] When the road traffic lights break down, it is often necessary to use temporary traffic lights to direct. Most of the existing temporary lights do not have a locking function, and the stability is relatively poor. Contents of the invention [0004] The object of the present invention is to provide a lifting signal lamp with a locking function, so as to solve the problems raised in the above-ment...
