The locking skirt 57 is formed with a locking projection 55 formed on the outside to prevent the rotation of the pressing unit 60 to be described later. The engaging piece protrusion may be a protrusion shape formed on the outside or a protrusion formed on the inside. In addition, other shapes that may prevent rotation of the pressing unit 60 inserted into the inside may be possible.

The engaging portion (not shown) of the expansion catching portion 50 is drilled into a shape and size substantially the same as the outer diameter of the elevating driving bar 30 to be fitted to the elevating driving bar 30. The expansion engaging portion 50 may be manufactured separately and coupled to the elevating driving bar 30, or may be manufactured integrally with the anchor 40 at the lower end of the anchor 40.

The elevating pressure unit is supported by the elevating portion 70 and the elevating portion 70 in which the female thread portion 73 is engaged with the male screw portion 32 of the elevating driving bar described above, and the elevating driving bar 40 is freely coupled to the elevating driving bar 40. The unit 60 is included. The elevating part 70 is formed with a female thread part 73 corresponding to the male screw part 32 of the elevating driving bar 30 on the inner side thereof, thereby engaging with the elevating driving bar 30 to perform the up and down movement.

The pressurizing portion 60 is upwardly sloping so that the inclination is formed on the outer periphery so that it can easily enter the inside of the expansion catching portion 50, that is, the cross-sectional shape is preferably a trapezoidal shape.

The pressing unit 60 is always in contact with the lifting unit 70 is formed with a locking portion 61 for preventing the rotation of the lifting unit so as not to rotate with the rotation of the lifting drive bar. The lifting unit 70 is closely supported by the pressing unit 60 when the lifting driving bar rotates, and is caught by the catching unit 61 and cannot rotate. Therefore, the lifting driving bar is rotated by the male screw unit of the lifting driving bar 30. Ascending and descending along the thread of (32). That is, the rotational movement of the elevating drive bar is converted into a linear movement by the screw coupling means so that the elevating portion is elevated.

In this embodiment, the pressurizing part 60 and the lifting part 70 are manufactured separately, but the pressing part 60 supports the lifting part 70 in close contact and the lifting part 70 is fixed, so that the pressing part 60 ) And the lifting unit 70 may be integrally manufactured, or may be in constant contact using a method such as welding and an adhesive. In addition, a washer bolt and the like may be used in which the lifting part and the pressing part are integrally formed and a female thread part is formed therein.

With this configuration, the process of constructing the eye-guided bottle according to the embodiment of the present invention will be described with reference to FIGS. 2 to 4 as follows.

First, the elevating drive bar 30 is inserted into the mounting hole 21 of the support unit 20, and the elevating drive bar 30 penetrates the support unit 20 and the anchor unit 40, and the male screw unit of the elevating drive bar 30 ( 32 to be exposed to the lower side of the anchor portion (40). As shown in FIG. 2, the expansion catching part 50, the pressing part 60, and the elevating part 70 are sequentially turned to the male screw part 32 side of the elevating driving bar 30 exposed to the lower side of the anchor 40. Combine.

First, the elevating drive bar 30 is rotated several times to temporarily fasten the elevating drive bar 30 and the elevating unit 70. Temporarily fasten the elevating driving bar 30 and the elevating unit 70 to the plurality of anchors in the same manner. In this way, the display portion 10 is press-fitted into the insertion hole 3 so that the plurality of anchor portions 40 are inserted into the plurality of insertion holes 3. Then, the lifting drive bar 30 is rotated by coupling a tool to a rotating ball structure working part (not shown) formed in the head 31 of the lifting drive bar 30. The elevating driving bar 30 is caught by the engaging portion 23 formed inside the guide portion 80, and the head 31 is no longer moved downward so as to rotate in place. When the elevating drive bar 30 rotates, the elevating part 70 which is screwed with the elevating drive bar 30 at the lower end of the anchor 40 is not rotated by the rotation preventing part 61 of the pressing part 60. Since it is not fixed, the ascending movement is carried on the thread of the male screw part 32 formed on the elevating driving bar 30.

 At this time, the pressing unit 60 for supporting the lifting unit 70 in close contact with each other by the upward movement of the lifting unit 70, in this process the pressing unit 60 is raised and the bottom surface of the anchor 40 It is pressed into the locking piece 57 of the expansion engaging portion 50 located in the. When the pressing portion 60 is press-fitted into the expansion catching portion 50, the inclined outer periphery of the pressing portion 60 is formed along the circumferential direction around the expansion catching portion 50. The lateral pressure is applied to the field, which causes the engaging skirt portions 57 to expand and extend radially outward of the anchor 40.

Here, it is preferable that the outer diameter of the pressing portion 60 has a sufficient value so that the locking piece 57 of the expansion catching portion 50 can be opened as much as possible.

On the other hand, when the lifting unit 70 is raised to one side of the lower end of the anchor 40 by the rotation of the elevating drive bar 30, the lower surface of the anchor 40 and the expansion catching portion 50, the pressing unit 60, the lifting unit ( 70 is in close contact with each other in order. In particular, the pressing portion 60 is in close contact with the through hole (not shown) of the expansion engaging portion 50, so that the engaging skirt portions 57 are radially outer side of the anchor 40 as shown in FIG. Fully expanded to

At this time, the end of the engaging skirt portion 57 penetrates the inner wall surface of the insertion hole 3 to support the inner wall surface, thereby preventing the anchor portion 40 from being separated from the anchor insertion hole 3. . In addition, the rotation preventing portion 61 of the pressing unit 60 is engaged with the locking projection 55 formed on the locking skirt 57 so as to support the inner wall surface in a fixed state without rotation.

On the other hand, if you want to remove the gaze induction rod (1) from the installation surface or the road, the lifting unit by coupling the tool (not shown) to the rotary ball structure working part (not shown) of the elevating drive bar 30 is inserted into the support 20 The lifting drive bar 30 is rotated in the direction in which the 70 descends. When the elevating drive bar 30 rotates, the elevating part 70 engaged with the male screw part 32 of the elevating drive bar 30 at the lower end of the anchor 40 is moved downward. When the lifting unit 70 moves downward, the pressing unit 60 which is in close contact with the lifting unit 70 is also lowered.

In this process, since the pressure of the pressurizing part 60 that pressurizes the locking piece 57 of the expansion catching part 50 disappears, the locking piece 57 supporting the inner wall surface of the anchor insertion hole 3 is removed. Will lose its support. At this time, when the display unit 10 is lifted up, the gaze induction bar 1 can be easily removed from the road surface.

As such, the eye-guided rod according to the embodiment of the present invention is easy to install and remove because it does not use an adhesive, and the engaging portion of the extension catching portion physically supports the inner wall surface of the anchor buried hole so that the Since it can be installed firmly, it is possible to reduce the deviation and flow of the eye-guided rod due to the impact of the vehicle driving on the road.

As shown in FIG. 5, the gaze induction bar according to another embodiment of the present invention is directly inserted into the insertion hole by the lifting driving bar without the anchoring portion, and the expansion catching portion coupled to the lower region of the lifting driving bar rotates the lifting driving bar. It extends radially by and supports the inner wall surface of the insertion hole. In this case, since the structure is simpler than the above-described embodiment, the installation may be easier.

      As described above, according to the present invention, there is provided an environment-friendly road marking facility, which can be easily installed without restriction of weather such as temperature and humidity without using an adhesive. In addition, there is provided a road marking facility that can be physically securely installed on the road surface of the road, and is resistant to impacts by which the engaging piece supports the inner wall surface of the anchor insertion hole to reduce the deviation and flow on the road.
