Description

Technical Field

[0001] The utility model relates to the technical field of road signs, in particular to a highly stable anti-rotation protruding road sign. Background Art

[0002] Road studs, also known as raised road markings, can be used on highways or other roads to mark center lines, lane dividing lines, edge lines, etc.; they can also be used to mark dangerous sections such as curves, entry and exit ramps, guide markings, road narrowing, road obstacles, etc.

[0003] Existing raised road signs include those without fixing rods and those with fixing rods. Road signs without fixing rods are very easy to fall off the road surface, while those with fixing rods are often connected to the road sign by threaded connections. After long-term use of the road sign, when it is impacted by heavy vehicles, the road sign and the fixing rod are easy to rotate or even fall off. The fixing rod itself is also round. When the road sign is installed on the road surface and the glue has not completely solidified, the road sign and the road surface hole are easy to rotate, which causes the road sign to need to be disassembled and reinstalled, which is very troublesome.

[0004] This case was created to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The purpose of the utility model is to provide a highly stable anti-rotation protruding road sign to solve the problems raised in the above background technology.

[0007] (II) Technical solution

[0008] To achieve the above purpose, the utility model is implemented through the following technical solutions: a highly stable anti-rotation protruding road sign, including a road sign and a fixing rod, one end of the fixing rod is detachably connected to the bottom surface of the road sign, the end of the fixing rod connected to the road sign is square, and a mounting hole is opened on the bottom surface of the road sign. The mounting hole is square and its size corresponds to the square end of the fixing rod, and the four corners of the square mounting hole are provided with convex grooves extending to both sides.

[0009] Preferably, the other end of the fixing rod is connected to a fastening rod, the fastening rod is provided with an annular bevel groove, the annular bevel groove is evenly distributed, the fastening rod is provided with two vertical fixing grooves, and the fixing grooves on both sides are opposite to each other on the fastening rod.

[0010] Preferably, the bottom surface of the road sign is provided with anti-skid ribs and a plurality of countersunk holes.

[0011] Preferably, a plurality of glue holes are provided on the inner bottom surface of the mounting hole.

[0012] (III) Beneficial effects

[0013] After adopting the above technical solution, the utility model has the following advantages compared with the prior art: the utility model is a highly stable anti-rotation protruding road sign. By setting a plug-in square mounting hole, when the glue is not completely solidified, the fixing rod and the road sign will not rotate. Similarly, the fixing grooves are provided on both sides of the fastening rod to prevent the fixing rod and the mounting holes of the road surface from rotating and falling off when the glue is not completely solidified. Similarly, compared with the road sign directly fixed on the road surface without a fixing rod, it is more difficult to fall off under the impact of heavy vehicles. And after the glue is completely solidified, the above design can still improve the stability between the road sign and the fixing rod, and between the fixing rod and the road surface, so that the protruding road sign is not easy to fall off under the impact of heavy vehicles, avoiding the safety hazard caused by the change of the reflection direction due to the turning and falling of the road sign. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the structure of the utility model;

[0015] In the figure: 1 road sign, 2 fixing rod, 3 mounting hole, 4 convex groove, 5 fastening rod, 6 annular inclined groove, 7 fixing groove, 8 countersunk hole, 9 glue hole, 10 anti-skid rib. DETAILED DESCRIPTION

[0016] The utility model is further described in detail below through the drawings and embodiments.

[0017] The utility model embodiment provides a high stability anti-rotation protrusion road sign, such as Figure 1 As shown, it includes a road sign 1 and a fixing rod 2, one end of the fixing rod 2 is detachably connected to the bottom surface of the road sign 1, the end of the fixing rod 2 connected to the road sign 1 is square, and a mounting hole 3 is opened on the bottom surface of the road sign 1. The mounting hole 3 is square and its size corresponds to the square end of the fixing rod 2. The four corners of the square mounting hole 3 are provided with convex grooves 4 extending to both sides. When glue is added and the fixing rod 2 is inserted into the mounting hole 3, excess glue will overflow into the convex groove 4, but will not overflow to the bottom surface of the road sign 1 to cause the road sign 1 to protrude, be raised and unstable on the road surface. Afterwards, the glue in the convex groove 4 solidifies and fixes the fixing rod 2 at the same time. By setting the plug-in square mounting hole 3, when the glue is not completely solidified, the fixing rod 2 and the road sign 1 will not rotate.

[0018] The other end of the fixing rod 2 is connected to a fastening rod 5, on which an annular bevel groove 6 is provided, which is evenly distributed. The fastening rod 5 is provided with two vertical fixing grooves 7, which are located opposite to each other on the fixing rod 5. The fixing grooves 7 are provided on both sides of the fastening rod 5 to prevent the fixing rod 2 and the mounting hole on the road surface from rotating and falling off when the glue is not completely solidified. Similarly, compared with the road sign 1 directly fixed on the road surface without the fixing rod 2, it is more difficult to fall off under the impact of heavy vehicles. And after the glue is completely solidified, the above design can still improve the stability between the road sign 1 and the fixing rod 2, and between the fixing rod 2 and the road surface, so that the protruding road sign is not easy to fall off under the impact of heavy vehicles.

[0019] The bottom surface of the road sign 1 is provided with anti-skid ribs 10 and a plurality of countersunk holes 8 to further improve the stability between the road sign 1 and the road surface. The inner bottom surface of the mounting hole 3 is provided with a plurality of glue holes 9, and the glue holes 9 and the convex grooves 4 are also used to accommodate excess glue to further improve the firmness between the fixing rod 2 and the road sign 1.

[0020] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
