Fastening device of urban road sign

Abstract

The invention discloses a fastening device of an urban road sign. The device comprises a fixing rack (9) and a sign support (8), wherein a clamping slot (920) is arranged in a vertical column (92) of the fixing rack (9); the clamping slot (920) is composed of an upper clamping part (921), a middle slope transition part (922) and a lower wide mouth part (923) which are arranged from upper part to lower part in sequence; a blocking head (91) is arranged at the left end part of a horizontal bar (82) of the sign support (8); the blocking head (91) is used for passing through the vertical column (92) from the lower wide mouth part (923) and capable of moving upwardly in the clamping slot (920) until moving into the upper clamping part (921), so that the blocking head (91) is stopped in the axial direction of the horizontal bar (82), and is located in a front and rear direction which is axially orthogonal with the horizontal bar (82).

Description

technical field [0001] The invention relates to the field of road traffic, in particular to a fastening device for an urban 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 diffic...

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
