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).

An urban traffic road sign board fastening device comprises a fixing frame (9) and a sign board support (8). A vertical column (92) of the fixing frame (9) is provided with a clamping groove (920) which is formed by an upper clamping portion (921), a middle slope transition portion (922), and a lower wide opening portion (923) which are arranged sequentially from top to bottom; a clamping head (91) is arranged at the end part of the left side of a horizontal cross rod (82) of the sign board support (8) and is used for penetrating through the vertical column (92) from the lower wide opening portion (923). The clamping head can move in the clamping groove (920) upwards to the upper clamping portion (921), so that the clamping head (91) is stopped in the axial direction of the horizontal cross rod (82), and location in a front-back direction orthorhombic to the axial direction of the horizontal cross rod (82) can be achieved.

The invention relates to a fastening device for a municipal traffic signpost. The fastening device comprises a fixing frame (9) and a signpost bracket (8), wherein a clamping slot (920) is arranged in a vertical column (92) of the fixing frame (9), and is composed of an upper clamping part (921), a middle slope transition part (922) and a lower wide opening part (923) which are arranged in turn from top to bottom; a chuck (91) is arranged on the left end part of a horizontal cross bar (82) of the signpost bracket (8), passes through the vertical column (92) from the lower wide opening part (923), and can upwards move in the clamping slot (920) till reaching the upper clamping part (921), the chuck can be stopped along the axial direction of the horizontal cross bar (82) and can be positioned along the axial orthometric front-and-back direction of the horizontal cross bar (82).

A simple road traffic sign board fastening device comprises a fixing frame (9) and a sign board support (8), wherein a vertical column (92) of the fixing frame (9) is internally provided with a clamping groove (920) formed by an upper clamping part (921), a middle slope transition part (922) and a lower wide opening part (923) which are sequentially arranged from top to bottom; a clamping head (91) is arranged at the end part of the left side of a horizontal cross rod (82) of the sign board support (8) and is used for penetrating through the vertical column (92) from the lower wide opening part (923), the clamping head can move in the clamping groove (920) upwards to the inside of the upper clamping part (921), so that the clamping head (91) is stopped in the axial direction of the horizontal cross rod (82), and location in a front-back direction orthorhombic to the axial direction of the horizontal cross rod (82) can be achieved.

The invention provides a direction board fastening and mounting device for a municipal road. The direction board fastening and mounting device comprises a fixing frame (9) and a direction board bracket (8), wherein a vertical column (92) of the fixing frame (9) is internally provided with a clamping groove (920) composed of an upper clamping part (921), a middle inclined plane transition part (922) and a lower wide-opening part (923), which are arranged in sequence 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) and is used for penetrating through the vertical column (92) from the lower wide-opening part (923); and the chuck (91) can upward move into the upper clamping part (921) in the clamping groove (920), so that the chuck (91) can be stopped in the axial direction of the horizontal transverse rod (82) and is positioned in the axially orthogonal front and back directions of the horizontal transverse rod (82).

A road traffic indicator fastening assembly with a fastening indication lamp comprises a fixing frame (9) and an indicator support (8). 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 sequentially arranged from top to bottom is formed in a vertical column (92) of the fixing frame (9). A chuck (91) is arranged at the end portion of the left side of a horizontal transverse rod (82) of the indicator support (8) and used for penetrating the vertical column (92) from the lower wide opening part (923) and can move in the clamping groove (920) upwards into the upper clamping part (921) so as to stop the chuck (91) in the axial direction of the horizontal transverse rod (82) and be positioned in the front and back direction orthotropic with the axial direction of the horizontal transverse rod (82).

A fastening installation device for a municipal traffic sign, comprising a fixing frame (9) and a sign support (8), wherein the vertical column (92) of the fixing frame (9) is provided with a top-to-bottom The clamping groove (920) composed of the upper clamping part (921), the intermediate slope transition part (922), and the lower wide mouth part (923) arranged in sequence, wherein the horizontal bar of the sign bracket (8) ( 82) is provided with a chuck (91) at the left end for passing through the vertical column (92) from the lower wide mouth (923) and being able to go upward in the clamping groove (920) move into the upper clamping portion (921) so as to block the chuck (91) in the axial direction of the horizontal bar (82) and to be perpendicular to the axial direction of the horizontal bar (82) Positioning is achieved in the front-back direction.
