Rotatable mounting bracket for pavement notice board

Abstract

The invention discloses a rotatable mounting bracket for a pavement notice board. The rotatable mounting bracket comprises a main supporting rod, a solid structure of an integrated structure is arranged in the center of the top of the main supporting rod, and a main hollow shell is mounted in the center of the interior of the top end of the main supporting rod. The guideboard can rotate along withwind when bearing the wind action, so that the acting force of wind on the guideboard and the whole support is reduced, the service life of the guideboard and the support is prolonged, the wind resistance of the guideboard and the support is improved, and the rotating direction can be changed into longitudinal hydraulic pressure change when the wind action occurs; hydraulic pressure can achieve torque control over the rotating direction under the elastic effect of the spiral spring, due to the fact that the device adopts conversion from rotating driven to longitudinal driving, the appearanceof the device is simpler, meanwhile, after side face installation, due to the fact that the gravity is located on one side, friction of the side face gravity to a rotating part in the rotating processcan be reduced. Therefore, the rotation work can be conveniently carried out, and the sensitivity of parts during work is improved.

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...
