Pedestrian crossing voice prompt column with buffering and anti-collision functions

Abstract

The invention discloses a pedestrian crossing voice prompt column with buffering and anti-collision functions, and belongs to the technical field of pedestrian crossing voice prompt columns. The voiceprompt column comprises a base. A first rotating ball is movably arranged in an inner cavity of the first rotating groove. A column body is movably arranged at the top of the second rotating ball. Asecond rotating groove matched with the second rotating ball is formed in the middle of the bottom side wall of the column body. The bottom side wall of the supporting spring is connected with the topside wall of the base. The outer side wall of the column body is movably sleeved with a buffer air bag. Force bearing plates are evenly arranged on the outer sides, away from the column body, of thebuffer air bags. According to the device, the first rotating ball rotates in the inner cavity of the first rotating groove, and the second rotating ball rotates in the inner cavity of the second rotating groove, so that the column body inclines in the opposite direction, the collision with an attacking object is avoided, the buffering and anti-collision effects are achieved, damage to electronic devices in the inner cavity of the column body is avoided, and the service life of the device is prolonged.

Description

Technical field [0001] The invention relates to the technical field of pedestrian crossing voice prompt columns, in particular to a pedestrian crossing voice prompt column with buffering and anti-collision functions. Background technique [0002] Pedestrian crossing voice prompt is a voice prompt device used to broadcast traffic light information at intersections. It is installed at intersections. Generally, intersections have a large number of people and complex situations. It is easy to hit pedestrian crossing voice prompts, and pedestrians often cross the street. When hit, it is easy to cause the internal parts of the column to loosen or damage, which affects the normal service life of the device. Therefore, a pedestrian crossing voice prompting column with a buffer and anti-impact function is needed. Summary of the invention [0003] The purpose of the present invention is to provide a pedestrian crossing voice prompt column with buffer and anti-collision function to solve the...
