Traffic sign rod

Abstract

The invention discloses a traffic sign rod. The traffic sign rod comprises a stand column, a cross beam and signboards. A sliding groove is formed in the side of the stand column, and a lead screw transmission mechanism is installed in the sliding groove. An inclined support is hinged to the output end of the lead screw transmission mechanism. The top end of the inclined support is hinged to the bottom of the middle section of the cross beam. A main beam, a telescopic beam and a rotating beam are arranged on the cross beam from right to left. The telescopic beam is connected to the left side of the main beam in a sleeving mode. The rotating beam is connected to the telescopic beam in a sleeving mode. An I-shaped connecting piece is fixed to the outer side of the left end of the rotating beam, the signboards are fixed to the front and back of the I-shaped connecting piece separately, a rubber block is arranged under the I-shaped connecting piece, springs are arranged on both sides of the front side of the rubber block, and the outer sides of the springs are fixedly connected with the inner sides of the signboards. According to the traffic sign rod, the cross beam is three-section design, and the telescopic beam can realize automatic extending and contraction and adjust the extension length according to the actual demand to ensure that a driver can see clearly; the signboards matched with the rotating beam can prevent the signboards from being collided and deformed to a certain extent; the main beam can be lowered or raised under the action of the lead screw transmission mechanism, and the safety of maintenance personnel is ensured.

Description

Technical field [0001] The invention belongs to the field of road traffic indicating equipment, and specifically relates to a traffic sign pole. Background technique [0002] Traffic signs have a guiding role for vehicles on the road and ensure traffic order. Common traffic sign poles include fixed poles, beams and signage. In actual use, in order to avoid trees and facilitate the observation of drivers, the beams are generally extended. It is long, its own structure is extremely unbalanced, and a pole with sufficient strength is required. In addition, if maintenance and replacement of sign boards are required, mechanical equipment must be used to climb up and maintain in the middle of the road, endangering the life of maintenance personnel. Summary of the invention [0003] In view of the shortcomings of the prior art, the present invention provides a traffic sign pole that is not easily damaged and is easy to maintain. [0004] The present invention is realized through the follow...

Problems solved by technology

[0002] Traffic signs guide vehicles on the road to ensure traffic order. Common traffic sign poles include fixed poles, beams and signs. The length of the road is long, and the force on its own structure is extremely unbalanced, so a pole with sufficient strength is required. In addition, if maintenance and replacement of signboards are required, mechanical equipment needs to be used to climb up, and the maintenance is in the middle of the road, which endangers the life safety of maintenance personnel.
