Abstract
The utility model discloses an anti-collision road signboard, comprising a road signboard and a vertical post, wherein a flange is fixedly connected at the upper part of the vertical post and is fixedly connected with a supporting rod; the supporting rod is of a cylindrical structure, one end of the supporting rod is processed with threads, and a roller capable of rotating around the center is sheathed at the middle part of the supporting rod; and the road signboard is fixedly connected with an excircle shell of the roller by a connecting block. The anti-collision road signboard disclosed by the utility model has the advantages that the rigid collision of an ultrahigh truck to the road signboard is avoided, the road signboard is prevented from being cracked up, and the service life of the road signboard is prolonged, and simultaneously also has the advantages of easiness in manufacture and convenience in installation and the like.
Description
Technical field
The utility model relates to a kind of road direction board, refers in particular to a kind of crashproof road direction board.
Background technology
Road direction board commonly used all is fixedly mounted on column one side, is positioned at the top on a side line road, as the lorry of excessive height below the road direction board through out-of-date, because driver inattention usually causes the road direction board to be damaged.
The utility model content
Problem to be solved in the utility model is the deficiency that overcomes in the background technology, a kind of crashproof road direction board is provided, this crashproof road direction board, the position is unfixing, when the superelevation lorry is run into the road direction board from following process, the road direction board can forward be avoided along the lorry travel direction, and after lorry was travelled over, the road direction board then recovered the normal position automatically.
For addressing the above problem, the utility model is taked following technical scheme:
A kind of crashproof road direction board of the present utility model, comprise road direction board, column, the fixedly connected flange in described column top, described flange is fixedly connected with pole, and described pole is cylindrical structure, and an end is processed with screw thread, described pole middle part is set with can be around the cylinder of its center rotation, described road direction board is fixedlyed connected with the outer round casing of cylinder by contiguous block, and when external force acts on the road direction board, the road direction board will rotate along the pole center with cylinder.The two ends installed inside of described cylinder has bearing, the inner ring of described bearing becomes interference fit with pole, the outer ring of described bearing becomes interference fit with the outer round casing of cylinder, one end of described cylinder tightens up by nut, the two ends of described cylinder are equipped with end cap, end cap is the collar plate shape structure of hollow, and the external diameter of external diameter and cylinder coincide.
A kind of crashproof road direction board of the utility model, because being set with at the pole middle part can be around the cylinder of its center rotation, and the road direction board is fixedlyed connected with the outer round casing of cylinder by contiguous block, therefore avoided the rigid bump of superelevation lorry to the road direction board, prevented that the road direction board from being broken, prolong the application life of road direction board, simultaneously, also had easy manufacturing, advantage such as easy for installation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the lateral view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, crashproof road direction board of the present utility model, comprise road direction board 1, column 2, the fixedly connected flange 5 in described column 2 tops, described flange 5 is fixedly connected with pole 6, and described pole 6 is cylindrical structure, and an end is processed with screw thread, described pole 6 middle parts are set with can be around the cylinder 3 of its center rotation, and described road direction board 1 is fixedlyed connected with the outer round casing 8 of cylinder 3 by contiguous block 4.
The two ends installed inside of described cylinder 3 has bearing 7,6 one-tenth interference fit of the inner ring of described bearing 7 and pole, 8 one-tenth interference fit of outer round casing of the outer ring of described bearing 7 and cylinder 3.
One end of described cylinder 3 tightens up by nut 10.
The two ends of described cylinder 3 are equipped with end cap 9.
The collar plate shape structure that described end cap 9 is hollow, the external diameter of external diameter and cylinder 3 coincide.
Should be noted that; the above is preferred embodiment of the present utility model only, is not limited to present embodiment, and is all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
