A fastening device for municipal road signs

Abstract

The invention provides a fastening device of a municipal road indication board. The fastening device comprises a fixed frame (9) and an indication board bracket (8), wherein a vertical column (92) of the fixed frame (9) is internally provided with a clamping groove (920) which is sequentially provided with an upper clamping part (921), a middle inclined plane transition part (922) and a lower width-opening part (923) from top to bottom; a chuck (91) is arranged at the end part of the left side of a horizontal transverse rod (82) of the indication board bracket (8), is used for penetrating through the vertical column (92) from the lower width-opening part (923), and can move upwards in the clamping groove (920) into the upper clamping part (921), so that the chuck (91) is stopped in the axial direction of the horizontal transverse rod (82), and the chuck realizes positioning in the front and back direction orthogonal with 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 municipal road 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 dif...

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
