A fastening device for road traffic signs

Abstract

The invention relates to a fastening device for a road traffic indicating board. The fastening device comprises a fixing frame (9) and an indicating board bracket (8), wherein a clamping groove (920) which is formed by an upper clamping part (921), a middle bevel transition part (922) and a lower wide opening part (923) in sequential arrangement from top to bottom is formed in a vertical column (92) of the fixing frame (9); a clamping head (91) is arranged at the end part of the left side of a horizontal transverse rod (82) of the indicating board bracket (8), is used for penetrating through the vertical column (92) from the lower wide opening part (923), and can upwards move in the clamping groove (920) to the upper clamping part (921); therefore, the clamping head (91) is blocked in an axial direction of the horizontal transverse rod (82), and besides, positioning is realized in a front-back direction which is orthogonal to the axial direction of the horizontal transverse rod (82).

Description

technical field [0001] The invention relates to the field of road traffic, in particular to a fastening device for a road traffic sign. Background technique [0002] Road traffic signs often need to be firmly installed to avoid potential safety hazards. At the same time, due to factors such as road construction or changes in road planning and construction, road signs often need to be replaced to adapt to changing information. However, due to factors such as a high position and often being located near the roadway, the installation and replacement operations need to be reduced in time. Some existing fixing methods often need more time-consuming. And although some easy-to-install fixing methods are easy to operate, it is difficult to realize the needs of fastening installation. In particular, because the sign is easy to bear a large force load under conditions such as wind force, it is easy to form a force and moment load on the fixing part. Some existing devices are diffi...

Problems solved by technology

Some existing fixing methods often take more time

However, although some easy-to-install fixing methods are convenient to operate, it is difficult to achieve the needs of fastening installation.

Especially because the sign is easy to bear a large force load under conditions such as wind force, which is easy to form a force and moment load on the fixed part

Some existing devices are difficult to meet these specific requirements while reducing the disassembly operation time
