Description

Technical Field

[0001] This application relates to the field of road sign technology, and in particular to a movable and variable 100-meter marker device. Background Technology

[0002] Highway markers are signs placed on the right-hand guardrail of highways, with one every 100 meters. The main purpose of these signs is to help drivers know their exact location on the highway. Drivers can report their location in kilometers and meters to rescue personnel in case of an emergency, allowing rescuers to quickly pinpoint their location, which can greatly shorten rescue time and reduce the risk of secondary accidents.

[0003] In the operation and management of highways, accurate and clear location markings are crucial for the safe travel of drivers and passengers and for emergency rescue work. Traditional 100-meter markers are basically made of aluminum alloy, are circular in shape, and have reflective film on their surface. They are installed on the side of the road at each kilometer marker, with one 100-meter marker every 100 meters, and are attached to the corrugated beam guardrail.

[0004] Because mileage markers are used outdoors, they are inevitably affected by factors such as wind, sun, rain, snow, and mud splashes. Over time, the lettering on 100-meter mileage markers can easily become blurred and the paint can peel off. Since traditional 100-meter mileage markers are a single unit with the kilometer and meter numbers directly coated on the surface, they are unique. Replacing them requires replacing the entire marker, which obviously results in high maintenance costs and low replacement efficiency. Utility Model Content

[0005] This application provides a movable, variable 100-meter marker device, which can effectively reduce the maintenance cost of markers and improve the efficiency of replacement.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A movable, variable 100-meter marker device includes a support bracket, with a fixed base welded to the bottom of the support bracket for fixing and installing on a steel plate guardrail or a bridge concrete guardrail; an arc-shaped bracket is installed at the upper end of the support bracket, and a marker is installed on the inner side of the arc-shaped bracket.

[0008] The sign has a meter display and a kilometer display on its surface, with the meter display located directly above the kilometer display;

[0009] The kilometer marker includes a first embedded frame and a first license plate. The first license plate is inserted into the first embedded frame, and the side of the first license plate with the kilometer number printed on it faces away from the marker within the first embedded frame.

[0010] Furthermore, the number of the first embedded square and the number of the first license plate in the kilometer marker are both three, and the three first license plates are respectively inserted in the three first embedded squares, and the three first embedded squares are equally spaced along the horizontal direction on the surface of the marker.

[0011] Furthermore, the arc-shaped bracket and the sign are detachably connected together.

[0012] Furthermore, two rotating shafts are installed on the inner side of the arc-shaped bracket opening, and a hollow insert is fixedly connected to one of the opposite sides of the sign. The two rotating shafts are respectively inserted into the two hollow inserts, and they are connected together by pins.

[0013] Furthermore, a ball bearing is provided at the position where the rotating shaft is mounted on the arc-shaped bracket. The outer ring of the ball bearing is fixedly connected to the arc-shaped bracket, and the inner ring of the ball bearing is fixedly connected to the rotating shaft.

[0014] Furthermore, a counterweight is fixedly installed at the bottom of the sign.

[0015] Furthermore, the surface of the sign is provided with a reflective film.

[0016] Furthermore, the support bracket includes a mounting shaft, the lower end of which is welded and fixed to the fixed base, and the upper end of the mounting shaft is fitted with a sliding rod and the two are threaded together. The end of the sliding rod away from the mounting shaft is welded to the arc-shaped bracket.

[0017] Furthermore, the meter display includes a second embedded frame and a second plate, the second plate being inserted into the second embedded frame, and the side of the first plate with the meter printed on it facing away from the sign within the second embedded frame.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] The kilometer marker on the surface of this application consists of a first embedded frame and a first number plate. When the kilometer number becomes unclear due to the accumulation of time, the road maintenance worker only needs to remove the corresponding first number plate and replace it with a new second number plate. Compared with the existing kilometer markers, this not only reduces maintenance costs but also effectively improves replacement efficiency. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0027] like Figures 1-3 As shown, this application discloses a movable variable 100-meter marker device, which includes a support bracket 1, a fixed base 2 welded below the support bracket 1 for fixing and installing on a steel plate guardrail or a bridge concrete guardrail; an arc-shaped bracket 3 is installed at the upper end of the support bracket 1, and a sign 4 is installed on the inner side of the arc-shaped bracket 3.

[0028] The surface of sign 4 is equipped with a meter sign 5 and a kilometer sign 6, with the meter sign 5 located directly above the kilometer sign 6;

[0029] The kilometer marker 6 includes a first embedded frame 61 and a first license plate 62. The first license plate 62 is inserted into the first embedded frame 61, and the side of the first license plate 62 with the kilometer number printed on it faces away from the sign 4 inside the first embedded frame 61.

[0030] In the above embodiments, the structure of the first embedded frame 61 of this application is similar to the common display frame structure in the prior art, as long as it facilitates the installation and removal of the first license plate 62. Figure 2 As shown, this is a preferred embedded frame structure of the present application, which is made of transparent plastic sheet. It has an opening at one end so that workers can insert or remove the license plate from the embedded frame. The opening side is provided with fixing bolts. After the license plate is inserted, tightening the bolts can fix the license plate in the embedded frame. Loosening the bolts allows the worker to pull the license plate out of the embedded frame.

[0031] The fixing base 2 of this application is made of high-strength stainless steel. During use, it can be firmly fixed to the guardrail on the right side of the highway by pre-embedded bolts or expansion bolts. In this way, the fixing base 2 not only has a certain weight itself, but is also tightly fixed to the guardrail by bolts, so as to ensure that when vehicles pass by, the entire marker can easily resist the impact of external environment such as airflow generated by vehicle movement.

[0032] The kilometer marker 6 of this application consists of a first embedded frame 61 and a first number plate 62. When the kilometer marker becomes illegible due to fading lettering or paint peeling over time, the road maintenance worker only needs to remove the corresponding first number plate 62 and replace it with a new one. Compared with the integrated structure of existing kilometer markers, this not only reduces maintenance costs but also effectively improves replacement efficiency.

[0033] Furthermore, such as Figure 1 and Figure 3 As shown, there are three first embedded squares 61 and three first license plates 62 in the kilometer marker 6. The three first license plates 62 are respectively inserted into the three first embedded squares 61, and the three first embedded squares 61 are equally spaced along the horizontal direction on the surface of the sign 4.

[0034] In the above embodiments, the kilometer numbers on a single road are generally within three digits. Therefore, the number of first signs 62 in the kilometer marker 6 of this application is set to three (in actual use, if the road is special and the kilometer number to be recorded may be greater than three digits, the number of first embedded boxes 61 can be increased to more than three; if it is less than three digits, the first sign 62 can be inserted into only one or two first embedded boxes 61). The mile markers are set every 100 meters, and the meter marker 5 can use a single number to indicate the specific location between two kilometers. For example, if the meter marker 5 displays the number "1", it means that the current location is the kilometer number composed of three first signs 62 plus 100 meters. Therefore, only one meter marker is needed in this application. Moreover, each first sign 62 in this application is inserted into an independent first embedded box 61. In this way, when the worker independently adjusts the first sign 62 in any first embedded box 61 according to the working conditions of the 100-meter mile marker, he will not be disturbed by other first signs 62.

[0035] Furthermore, such as Figure 1 and Figure 3 As shown, the arc-shaped bracket 3 and the sign 4 are detachably connected together.

[0036] In the above embodiments, the sign 4 and the arc-shaped bracket 3 are detachably connected together. When the sign 4 is deformed or damaged, the maintenance worker only needs to remove the damaged sign 4 from the arc-shaped bracket 3 and install the new sign 4. This avoids the need to replace the entire sign when the sign 4 is deformed or damaged, and can also reduce maintenance costs and improve maintenance efficiency to a certain extent.

[0037] Furthermore, such as Figure 1 and Figure 3 As shown, two rotating shafts 7 are installed on the inner side of the opening of the arc-shaped bracket 3. A hollow insert 8 is fixedly connected to one of the opposite sides of the nameplate 4. The two rotating shafts 7 are inserted into the two hollow inserts 8 respectively, and they are connected together by pins.

[0038] In the above embodiments, the pin of this application can be a set of bolts and nuts. Both the hollow insert 8 and the rotating shaft 7 are provided with through holes. When the worker needs to install the sign 4 on the rotating shaft 7, he can first put one of the hollow inserts 8 of the sign 4 on the rotating shaft 7, and then move the entire sign 4 along the direction of the rotating shaft 7 until the other hollow insert 8 can be aligned with the other rotating shaft 7. Adjust the position of the sign 4 until the through holes on the two hollow inserts 8 are aligned with the through holes on the rotating shaft 7 at their respective positions. Then, use bolts to insert into the aligned through holes and screw on nuts to fix them. In this way, the sign 4 can be installed on the arc-shaped bracket 3. When the sign 4 needs to be replaced, the above method can be reversed.

[0039] Furthermore, such as Figure 3 As shown, a ball bearing 9 is installed at the position where the rotating shaft 7 is mounted on the arc-shaped bracket 3. The outer ring of the ball bearing 9 is fixedly connected to the arc-shaped bracket 3, and the inner ring of the ball bearing 9 is fixedly connected to the rotating shaft 7.

[0040] In the above embodiments, after installing the ball bearing 9 between the rotating shaft 7 and the arc-shaped bracket 3 in the manner described above, the sign 4 can have a certain rotational ability when in use. In this way, when a vehicle accidentally hits the guardrail, the movable nature of the 100-meter marker can disperse the impact force by rotating when it is hit, thereby reducing the risk of damage and extending its service life.

[0041] Furthermore, such as Figure 1 and Figure 3 As shown, a counterweight 10 is fixedly installed at the bottom of sign 4.

[0042] In the above embodiments, since the sign 4 of this application has a certain degree of mobility during use, when the wind blows across the surface of the sign 4, the sign 4 may unnecessarily flip over. To improve this situation, this application adds a counterweight 10 to the bottom of the sign 4 to effectively reduce the risk of the sign 4 unnecessarily flipping over due to wind force during normal use. In addition, compared with traditional mileage signs, if they tilt due to accident during use, the information on the surface of the mileage sign is difficult for the driver to see directly. With the addition of the counterweight 10 on the lower side of the sign of this application, even if the main body of the mileage sign tilts, the sign 4 of this application can be kept in a vertical state with respect to the horizontal plane under the gravity of the counterweight 10. This effectively solves the above-mentioned problems existing in the existing integrated fixed mileage signs when tilted.

[0043] Furthermore, the surface of sign 4 is provided with a reflective film.

[0044] In the above embodiments, the reflective film set on the surface of the sign 4 can conspicuously display its position information to the driver when it comes into contact with vehicle lights at night, so as to ensure that the driver can clearly know his specific position on the road at night.

[0045] Furthermore, such as Figure 1 and Figure 3 As shown, the support bracket 1 includes a mounting shaft 11. The lower end of the mounting shaft 11 is welded and fixed to the fixed base 2. The upper end of the mounting shaft 11 is fitted with a sliding rod 12 and the two are threaded together. The end of the sliding rod 12 away from the mounting shaft 11 is welded to the arc-shaped bracket 3.

[0046] In the above embodiments, the mounting shaft 11 in the support bracket 1 is fixedly connected to the fixed base 2, and the sliding rod 12 in the support bracket 1 is fixedly connected to the arc-shaped bracket 3. The sliding rod 12 is threadedly connected to the mounting shaft 11. In this way, when in use, the worker can connect the arc-shaped bracket 3 with the sign 4 and the fixed base 2 fixedly installed on the roadside guardrail into a whole by screwing the sliding rod 12 on the mounting shaft 11. Correspondingly, when the arc-shaped bracket 3 has a problem, the worker does not need to remove the fixed base 2 from the guardrail, but only needs to replace the arc-shaped bracket 3 with the sliding rod 12. This makes the 100-meter marker of this application more flexible to use, more convenient to maintain, and lower in cost.

[0047] Furthermore, such as Figure 4 As shown, the meter sign 5 includes a second embedded frame 51 and a second sign 52. The second sign 52 is inserted into the second embedded frame 51, and the side of the second sign 52 with the meter number printed on it faces away from the sign inside the second embedded frame 51.

[0048] In the above embodiments, the second embedded frame 51 and the first embedded frame 61 of this application have the same structure. The main difference lies in their specifications. Since the second sign 52 displaying the meter reading is larger, the specifications of the second embedded frame 51 in this application are larger than those of the first embedded frame 61 in order to accommodate the larger second sign 52. By also setting the meter reading sign 5 of this application to this detachable structure, when problems such as unclear meter readings occur on the meter reading sign 5, maintenance workers can replace only the second sign 52 displaying the meter reading without replacing the sign 4. This further improves the flexibility and convenience of this application in actual use.

[0049] The implementation principle of this embodiment is as follows: The sign 4 of this application uses a circular aluminum alloy panel with a diameter of φ300mm. There is a gap of 1~2cm between the installed sign 4 and the arc-shaped bracket 3 to reserve space for the sign 4 to move. The length of the entire support bracket 1 is 250mm (that is, the vertical distance between the lowest point of the arc-shaped bracket 3 and the upper surface of the fixed base 2 after the mounting shaft 11 and the slide rod 12 are assembled). Because the driver's line of sight is about 1.3m during normal driving, while the height of the guardrail is usually about 1m, setting the height of the entire support bracket 1 to 250mm can make the height of the sign 4 as close as possible to the driver's line of sight during driving, so that the driver can easily observe the information on the sign 4 during driving. The mounting shaft 11 in the support bracket 1 of this application is a steel pipe with a diameter of 60mm. The steel pipe with this diameter can ensure that it can provide stable support for the sign 4 and other related components to prevent them from bending and deforming during use.

[0050] In actual use, workers can first fix the fixed base 2 firmly to the guardrail on the right side of the highway with pre-embedded bolts or expansion bolts, then put the slide rod 12 on the external thread part of the upper end of the mounting shaft 11 and tighten it to make the two firmly connected. Then, insert the hollow inserts 8 on both sides of the sign 4 into the two rotating shafts 7 on the inner side of the opening end of the arc-shaped bracket 3 above the slide rod 12 (the sign 4 has meter information on it), and use pins to connect them firmly. Then, put the first sign 62 with the kilometer number printed on it into each of the first embedded squares 61 one by one.

[0051] When the numbers on sign 4 (number 62) become unclear, workers can simply replace them with the corresponding numbered sign at the appropriate location on sign 4. If the arc-shaped bracket 3 or the sliding rod 12 is rusted, worn, or deformed, workers can simply remove the sliding rod 12 from the mounting shaft 11 and replace it with a new arc-shaped bracket 3 containing the new sliding rod 12. If the old sign 4 is functioning correctly, it can be installed on the new arc-shaped bracket 3 for continued use. If sign 4 is deformed, the pins on the hollow inserts 8 on both sides of sign 4 and the rotating shaft 7 can be removed, and a new sign 4 can be installed. Compared to the existing integrated structure of 100-meter marker signs, this application allows for replacement of only the problematic areas without dismantling the entire marker body. This simple and quick operation saves significant manpower, resources, and time, improving road maintenance efficiency. Furthermore, when the kilometer marker plate malfunctions or requires replacement of the first plate 62 due to other factors, workers only need to remove the old first plate 62 and insert the new one; there is no need to replace the entire 100-meter marker plate. This significantly shortens installation time and reduces traffic disruption. Additionally, the sign 4 in this application's 100-meter marker plate has a rotatable feature, allowing it to disperse impact force through rotation upon collision, reducing the risk of damage and extending its service life.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
