In addition, Figure 4 is a side cross-sectional view showing a state in which the road sign bottle with a buffer function of the present invention is installed on the ground of the road, Figure 5 is a view showing the operating state of the road sign bottle with buffer function of the present invention. 6 is a side cross-sectional view, Figure 6 is a side cross-sectional view showing a state in which the coupling ring is coupled to the buried portion according to the present invention.

First, the configuration of the present invention according to Figures 1 to 6 will be described.

As shown, the road sign bottle with a buffer function according to the present invention is embedded in the upper portion of the buried portion 100, the opening portion 100a and the opening 100a through the opening 100a And is inserted into the buried part 100 through the opening 100a of the buried part 100 so as to be laminated and coupled to an upper part of the elastic part 200. It is composed of a flow display unit 300.

1 and 2, the buried portion 100 is formed to form a cylindrical shape, and is formed by forming a plurality of guide holes 110 along the outer edge.

The flow display unit 300 is formed by forming a plurality of guide grooves 310 along the outer edge of the position corresponding to the guide hole 110 when inserted into the buried portion 100.

The guide hole 110 and the guide groove 310 are formed to have the same extension line position as the ground surface of the roadway 20 when the flow display part 300 is inserted and fixed inside the buried part 100. Will be.

The guide hole 110 is coupled to the guide coupling member 120.

That is, a plurality of guide coupling members 120 in the plurality of guide holes 110 formed on the outside of the buried part 100 so as to penetrate the guide hole 110 and then inserted into the guide groove 310. Combining configuration.

For example, the guide coupling member 120 is formed to cover the outer surface of the guide hole 110, the plate-shaped fixing plate 121 to be in close contact with the outside of the guide hole 110 and the fixing plate 121 of The guide hole 110 is formed when the guide hole 110 and the guide groove 310 are positioned on the same vertical line by being protruded on one side and the flow indicator 300 is inserted into the buried part 100. ) And the fixing pin 122 is configured to connect the guide groove 310.

3, the fixing pin 122 of the guide coupling member 120 is guide hole 110 of the buried part 100 when the buried part 100 and the flow display part 300 are coupled to each other. After insertion is installed to penetrate through the guide groove 310 of the flow display unit 300 is installed.

Accordingly, as shown in FIGS. 5 and 6, after installing the buried part 100 in the ground of the road 10, and installing the fluid display part 300 to be coupled to the inside of the buried part 100. The flow display part 300 may smoothly move up and down through the elastic part 200 positioned between the buried part 100 and the flow display part 300, and at the same time, the flow display part ( Even when the 300 flows up and down, the flow display part 300 through the fixing pin 122 of the guide coupling member 120 penetrates the guide hole 110 and is seated and coupled to the guide groove 310. The width of the upper and lower flows of) is adjusted and efficient up and down flow can be achieved without being separated from the buried part 100.

At this time, the compression plate 330 which is installed in close contact with the elastic portion 200 is further coupled to the lower end of the flow display unit 300.

The compression plate 330 is detachably coupled to the flow display unit 300 and has a cylindrical shape having a screw thread on the top thereof, and thus the flow display unit 300 is smoothly in close contact with the elastic unit 200. The lower surface of the flow display unit 300 is configured to smoothly lower the flow display unit 300 when it is exposed to the surface and lowered by the vehicle.

The compression plate 300 may be deleted by the user's selection, but in the present invention in order to enable the smooth up and down flow of the flow display unit 300 by the elastic unit 200 in the present design It is installed and used in the lower portion of the display unit 300.

In addition, the elastic portion 200 is formed of any one selected from urethane, rubber, compressed sponge.

This is to configure the flow display portion 300 coupled to the inside of the buried portion 100 to achieve a smooth up and down flow without complicated fastening means such as the conventional spring in the present invention as described above In the urethane, rubber, and the elastic sponge having elastic force can be conveniently applied according to the user's choice.

In addition, a plurality of reflecting plates 320 are further provided on the flow display part 300, and the reflecting plates 320 are formed of any one selected from reflecting glass, reflecting paper, fluorescent paint, and reflecting fiber.

The reflector 320 allows the driver to drive the road even on a blurred day or at night so that the boundary line of the road 20 can be more smoothly checked through a road sign provided with a buffer function installed on the ground of the road 20. In order to reflect the headlights of the car.

At this time, the reflective glass, reflective paper, fluorescent paint, reflective fiber is selected and applied by the user according to the environment of the workplace to manufacture the road sign bottle with a buffer function and the external environment of the place where the road sign bottle with a buffer function is installed.

In addition, as shown in FIG. 5, when the wheel 20 of the vehicle deviates from the flow display part 300, the flow display part 300 may return to its original position through the elastic part 200. .

That is, the elastic part 200, the compression plate 330, and the flow display part due to the inner air of the buried part 100 through the first air flow hole 300a and the second air flow hole 330a. When the up and down flow of the flow display unit 300 which is installed to be exposed to the ground of the road 20 is in close contact with the wheel 10 of the vehicle by preventing the up and down flow of the 300 is not performed smoothly. It will be made smoothly.

In addition, the contaminants generated from the outside through the first air flow hole (300a) is configured so as to prevent from entering the inside of the buried portion 100 as much as possible to impurity inside the buried portion 100 This prevents the flow of the up and down flow of the flow display panel 300.

In addition, a coupling groove 340 is further formed on one side of the flow display part 300 adjacent to the buried part 100 along the outer edge, and the coupling groove 340 is in close contact with the buried part 100. The contact ring 350 is further configured to combine.

This prevents damage to the flow display part 300, the elastic part 200, and the compression plate 330 coupled to the inside of the buried part 100 due to snow or rain penetrating into the buried part 100. It is to.

At this time, in the present invention, as shown in FIG. 6, the contact ring 350 is coupled between the flow display part 300 and the buried part 100, but the present invention is not limited thereto. The contact ring 250 may be installed to be coupled to one side of the compression plate 330, which is configured to prevent water from penetrating into the buried part 100 according to a user's selection. If it is a variety of changes can be applied.

On the other hand, Figures 7 to 10 show another embodiment of the present invention.
