Description

Technical Field

[0001] The utility model relates to a road crossing mark, in particular to a pressure-resistant road crossing mark. Background Art

[0002] Crossing signs are mainly used to remind drivers to pay attention to intersections or branches ahead, especially on rural roads. They are usually set up at village entrances and intersections to guide vehicles and remind pedestrians to pay attention. Crossing signs have obvious color contrast during the day and at night, and have a fluorescent reflection effect at night to remind main-line vehicles to be vigilant and prevent accidents caused by sudden appearance of vehicles on small branch roads. Crossing signs are usually made of metal materials such as steel or aluminum alloy and have high hardness. Reflective film is usually used on the outside to warn passing vehicles and people to reduce the occurrence of accidents.

[0003] When an accident occurs, the vehicle usually has a large kinetic energy and cannot brake. After the vehicle hits the crossing sign, the crossing sign is usually made of metal and has limited deformation during the collision, which usually brings a large impact force to the impacting vehicle and the driver, indirectly harming the driver. In addition, the crossing sign is very likely to be completely destroyed when hit or scratched by a vehicle, thus losing its warning function. Utility Model Content

[0004] In order to overcome the shortcomings of existing equipment that deformation is limited when being hit, which will bring huge impact force to drivers, the utility model provides such a pressure-resistant crossing sign.

[0005] The technical solution is as follows: a pressure-resistant level crossing sign, including a base, a fitting block, a clamping column, a warning column, a disc, a hook, a strong spring and a controller. A fitting block is fixedly connected to the bottom of the base, a clamping column is rotatably connected to the fitting block, a warning column is fixedly connected to the top of the clamping column, a disc is fixedly connected to the clamping column, a plurality of hooks are fixedly connected to the bottom of the disc and the inner wall of the base, a strong spring is fixedly connected between each two opposite hooks, and in the initial state, each strong spring is evenly stressed, the warning column is in a vertical state, and a controller is fixedly connected to the warning column.

[0006] Optionally, a reflective film is also included, and the reflective film is fixed to the warning column.

[0008] Optionally, it also includes a support frame, a warning light, a solar panel, a battery and a light sensor. The top of the warning column is fixedly connected to the support frame, the top of the support frame is fixedly connected to the warning light, both sides of the support frame are fixedly connected to solar panels, and the connection between the tops of the two solar panels is fixedly connected to a light sensor. The warning light, solar panel, battery and light sensor are all electrically connected to the controller.

[0009] Optionally, the reflective film is a bright color with two alternating colors.

[0010] Optionally, the warning column is made of rubber, the lower part of the warning column is solid, the upper and middle parts are hollow, and a ventilation hole is left on the warning column.

[0011] The beneficial effects of the utility model are as follows: 1. The utility model uses a strong spring to pull the warning column to a vertical state, and when hit, the warning column is deformed and tilted, thereby reducing the impact force brought to the vehicle by the warning column when hit.

[0012] 2. The utility model sends a signal to the controller through the light sensor, and then starts the warning light through the controller, so that the device can have a good warning effect even in dim weather.

DETAILED DESCRIPTION

[0020] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0021] Embodiment: A pressure-resistant crossing sign, such as Figure 1-Figure 6 As shown, it includes a base 1, a fitting block 2, a column 3, a warning column 4, a disc 5, a hook 6, a strong spring 7 and a controller 8. A fitting block 2 is welded at the center of the bottom of the base 1, and a column 3 is rotatably connected to the fitting block 2. A warning column 4 is welded on the top of the column 3. The warning column 4 is made of rubber, the lower part of the warning column 4 is solid, the upper middle part is hollow, and ventilation holes are left in the upper middle part of the warning column 4 in the longitudinal and transverse directions. The center of the warning column 4 and the center of the column 3 are located on the same vertical line, a disc 5 is welded on the upper part of the column 3, and a plurality of hooks 6 are welded circumferentially on the bottom of the disc 5 and the inner wall of the base 1, and a strong spring 7 is fixedly connected between each two opposite hooks 6. In the initial state, each strong spring 7 is evenly stressed, and the warning column 4 is in a vertical state. The right side of the lower part of the warning column 4 is connected to the controller 8 by bolts.

[0022] like Figure 1-Figure 5 As shown, it also includes a fixed block 10, a compression spring 11 and an extrusion block 12. Slide grooves are left on the front, back, left and right sides of the bottom of the base 1. The four slide grooves at the bottom of the base 1 are slidably connected with the fixed blocks 10. Two circular holes are left on the four fixed blocks 10. The sides of the four fixed blocks 10 close to the center of the base 1 are all inclined. Compression springs 11 are welded between the two sides of the four fixed blocks 10 and the base 1. The base 1 is slidably connected with the extrusion block 12, and the bottom of the extrusion block 12 is in contact with the top of the inclined side of the four fixed blocks 10.

[0023] like Figure 1 , Figure 5 and Figure 6 As shown, a reflective film 9 is also included. The upper part of the warning column 4 is pasted with the reflective film 9, and the reflective film 9 is a bright red and white color.

[0024] Before using the device, it is necessary to place the device on the flat ground or at an intersection on both sides of the road, and then press the extrusion block 12 downward. When the extrusion block 12 moves downward and contacts the inclined parts of the four fixed blocks 10, it will squeeze the four fixed blocks 10 to move away from each other. At this time, the eight compression springs 11 are all compressed. When the extrusion block 12 moves to the bottom, the eight compression springs 11 are all compressed to the limit state, and the sides of the four fixed blocks 10 close to the bottom center are all in contact with the outside of the extrusion block 12. The four fixed blocks 10 will be stuck by the extrusion block 12, and the four fixed blocks 10 will no longer move. At this time, the four fixed blocks 10 are The round holes on the fixed block 10 are all exposed from the base 1. At this time, it is necessary to drive steel nails for fixing into the ground through the two round holes on each fixed block 10. At this time, the base 1 is fixed to the ground by the steel nails. When pedestrians or vehicles pass by, the device can reflect light to the human eye through the reflective film 9. Because the reflective film 9 is bright red and white, it is easier to attract attention, so as to achieve a warning effect. Because the lower part of the warning column 4 is solid and the upper and middle parts are hollow, the center of gravity of the warning column 4 is lower and it is less likely to tip over. Ventilation holes are left in the upper and middle parts of the warning column 4 in the vertical and horizontal directions, so that the device will not be affected too much even when encountering strong winds.

[0025] When the vehicle hits the warning column 4, since the warning column 4 is made of rubber, the warning column 4 will be deformed to a certain extent at the impact point. At this time, the warning column 4 will tilt to the side away from the impact direction, and at the same time drive the disc 5 and the clamping column 3 to tilt to the direction away from the impact with the fitting block 2 as the center. The disc 5 will stretch the strong spring 7 close to the impact direction, and the strong spring 7 on the side away from the impact direction will release the force and shrink, so that the warning column 4 has a certain toughness, thereby reducing the impact force of the collision on the vehicle. When the accident vehicle is removed, the warning column 4, the clamping column 3, the disc 5 and the strong spring 7 are no longer subjected to force, and the strong spring 7 circumferentially at the bottom of the disc 5 returns to a state of force balance, pulling the clamping column 3, the disc 5 and the warning column 4 back to a vertical state. At this time, the device returns to its initial state.

[0026] like Figure 1-Figure 6 As shown, it also includes a support frame 13, a warning light 14, a solar panel 15, a battery 16 and a light sensor 17. The support frame 13 is welded to the top of the warning column 4, and the warning light 14 is connected to the center of the top of the support frame 13 by bolts. The solar panels 15 are connected to both sides of the top of the support frame 13 by bolts, and the light sensor 17 is connected to the top of the two solar panels 15 by bolts. The warning light 14, the solar panel 15, the battery 16 and the light sensor 17 are all electrically connected to the controller 8.

[0027] On sunny days, the solar panel 15 converts sunlight into electrical energy and stores the electrical energy in the battery 16. At night or other dark weather, when the light sensor 17 detects low light, it transmits a signal to the controller 8, which then activates the warning light 14 to alert passers-by and passing vehicles through the flashing light of the warning light 14.

[0028] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments may be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
