Triangular warning board

Abstract

The invention provides a triangular warning board. The triangular warning board comprises support rods, a base and a fixing block, wherein arc-shaped fixing grooves are arranged in the edge of the fixing block, the top ends of the support rods extend into the fixing grooves and are closely connected with the fixing grooves, the fixing block is provided with through holes, pin holes are arranged atthe top ends of the support rods, the fixing block is further provided with pins, the pins pass through the through holes and extend into the pin holes, the base is round-plate-shaped, a round guidegroove surrounding a center shaft is arranged in the upper surface of the base, sliders are arranged on the bottom ends of the support rods, the sliders are embedded in the round guide groove and perform circular motion, vacuum chucks are arranged on the bottom of the round plate, and light-reflecting coatings are arranged on the circumference surface of the base, the surfaces of the support rodsand the outer surface of the fixing block. The triangular warning board provided by the invention has the advantages that the stability is high, rotation can be realized, and the alarming range is wide.

Description

technical field [0001] The invention relates to the technical field of automobile warning devices, in particular to a warning triangle. Background technique [0002] When the car breaks down or in other emergency situations, the car needs to be temporarily parked, and a warning sign needs to be placed behind the body as a reminder to passing vehicles to prevent secondary accidents. According to different road sections, the position where the warning sign should be placed Different, the warning signs need to be placed 150 meters away on the high speed, so it is necessary to remind all directions in multiple directions, and generally ensure the formation of safety. The existing warning signs generally adopt the following two structures: [0003] First: Set up a triangular warning sign. By coating the warning sign with a reflective coating and using reflection to form a triangular-shaped light-emitting device, it plays a warning role. However, this kind of device has a small re...

Problems solved by technology

[0003] First: Set up a triangular warning sign. By coating the warning sign with a reflective coating and using reflection to form a triangular-shaped light-emitting device, it plays a warning role. However, this kind of device has a small reflective range and needs to be illuminated from the front to let the It plays a reflective role, and it is not easy to see directly from the side, especially when turning or at an intersection, it cannot directly play a warning role, affecting people's safety performance while driving, and there are potential safety hazards

[0004] Second: By installing a power supply and a light-emitting device on the warning sign, the commonly used light-emitting device is an LED light, which plays a warning role by shining and flashing, and emits light through the power supply, which also drives the self-rotation of the warning device body, but the cost is relatively large , and people need to pay attention to the power on the warning sign. If it is not used for a long time, the battery itself will wear out and cause it to fail to serve as a warning when it is really needed. It is inconvenient to use and the stability is not high.

[0005] There are also some light-weight warning signs, which are easy to be blown away during use. The faulty vehicle that loses the warning signs may cause secondary accidents. Therefore, some heavy objects are needed to press the warning signs to ensure the stability of the warning signs. , the operation is complicated and inconvenient
