Safe fastening structure for municipal road direction board

Abstract

The invention provides a safe fastening structure for a municipal road direction board. The safe fastening structure comprises a fixing rack (9) and a direction board bracket (8), wherein the interior of a vertical post (92) of the fixing rack (9) is provided with a clamping groove (920) composed of an upper clamping part (921), a middle slope transition part (922) and a lower wide-opening part (923) which are arranged in the sequence from top to bottom, a clamp head (91) is arranged on the end part of the left side of a horizontal cross bar (82) of the direction board bracket (8), passes through the vertical post (92) from the lower wide-opening part (923), and can move upwards in the clamping groove (920) till reaching the upper clamping part (921), so that the clamp head (91) is blocked in the axial direction of the horizontal cross bar (82), and the locating is realized in the front and back direction orthotropic to the axial direction of the horizontal cross bar (82).

Description

technical field [0001] The invention relates to the field of road traffic, in particular to a safety fastening structure 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 devic...

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
