Mounting bracket for a rotatable road surface warning sign

Abstract

The invention discloses a rotatable installation bracket for a road surface prompting board, which includes a main support rod, a solid structure with an integrated structure is arranged at the top center of the main support rod, and a main hollow shell is installed at the inner center of the top end of the main support rod . The invention can make the street sign rotate when it is subjected to wind force, thereby reducing the force of wind force on the street sign and the overall support, improving the service life and wind resistance performance of the street sign and support, and can change the direction of rotation when the wind force occurs. , into the change of longitudinal hydraulic pressure, the hydraulic pressure can realize the torque control of the rotation direction under the elastic action of the coil spring, because the device adopts the transformation between the rotation slave and the longitudinal drive, which makes the appearance of the device more simple, At the same time, after the side is installed, since the gravity is located on one side, it can reduce the friction of the side gravity on the rotating part during rotation, so as to facilitate the rotation work and improve the sensitivity of the parts during work.

Description

technical field [0001] The invention relates to the technical field of mounting brackets, in particular to a mounting bracket for a rotatable road surface warning sign. Background technique [0002] At present, the structure of the existing installation bracket for road signs is only a hollow bracket. In order to improve the wind resistance performance of the road sign after installation, it is necessary to use a thicker rod body for installation. On the one hand, the installation cost is increased. On the other hand , the components are fixed connections, resulting in an increase in the wind resistance of the road sign. Contents of the invention [0003] The object of the present invention is to provide a mounting bracket for a rotatable road surface warning sign, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a rotatable inst...
