An anti-blocking sign for expressway

Abstract

The invention discloses an anti-jam indicating plate for a highway. The anti-jam indicating plate for the highway comprises a box. The left side of the box is fixedly connected with a support column.The right side of the box is provided with a through hole communicated with the inner wall of the right side. The right side of the box is provided with two symmetrical protecting holes communicated with the inner wall of the right side of the box. The inner wall of the left side of the box is fixedly connected with a flexible spring. The anti-jam indicating plate for the highway is capable of, through installing a driving gear block and a transmission gear block, achieving the effect of picking up the indicating plate by using an impact force of heavy rain and hailstone in severe weather of the heavy rain and the hailstone, and through installing a driven gear plate and a buffering plate, achieving the effect of shielding and protecting the indicating plate, picking up and protecting theindicating plate through using the impact force of the heavy rain and the hailstone, achieving the effect of protecting the indicating plate in the severe weather so that the indicating plate is not damaged, and achieving the effect of improving service life of the indicating plate through protecting the indicating plate in the severe weather, thereby achieving the effect of conveniently and continuously performing indicating work on the highway for a long time.

Description

technical field [0001] The invention relates to the technical field of signage, in particular to an anti-blocking signboard for expressways. Background technique [0002] Expressways belong to high-grade highways. According to the "Technical Standards for Highway Engineering" of the Ministry of Communications of China, expressways refer to "highways that can adapt to the annual average day and night passenger car traffic volume of more than 25,000 vehicles, and are dedicated to high-speed driving in separate lanes and fully controlled access." Although countries have different names for expressways, they all refer to highways with more than 4 lanes, two-way separation, complete control of entrances and exits, and all use of three-dimensional intersections. The intersecting direct arterial is also called expressway. With the increasing number of vehicles on the expressway, the requirements for signage are also increased. The signboard is the sign indicating the direction. ...

AI Technical Summary

Problems solved by technology

[0003] As the situation of the expressway becomes more and more complicated, the requirements for the anti-blocking signs of the expressway are also increased. However, the existing anti-blocking signs of the expressway are very easy to cause the content of the signs to be damaged due to the severe weather of heavy rain and hail. The damage greatly affects the follow-up normal indication function, resulting in the lack of corresponding indication for passing vehicles and affecting traffic efficiency
