Detailed implementation manners

[0022] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the accompanying drawings and the description are considered to be exemplary in nature rather than restrictive.

[0023] The following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0024] As Figures 1-4 shown, the embodiment of the present utility model provides an anti-collision guardrail device, including: an anti-collision shell 1, two first gears 2 and a second gear 3 are rotatably fitted in the anti-collision shell 1, threaded rods 4 are threadedly fitted in both of the two first gears 2, sliding seats 5 are slidably fitted at the tops of the two threaded rods 4, two rotating seats 6 are rotatably fitted between the two sliding seats 5, a warning post 7 is fixedly installed between the two rotating seats 6, a sliding plate 8 is slidably fitted on one side of the anti-collision shell 1, two guide rods 9 that both penetrate the anti-collision shell 1 are fixedly installed on one side of the sliding plate 8, two springs 10 are fixedly installed between the sliding plate 8 and the anti-collision shell 1, a plurality of rotating assemblies 11 are fixedly installed on one side of the sliding plate 8, and two guide strips 18 for guiding the two threaded rods 4 respectively are fixedly installed in the anti-collision shell 1.

[0025] In this embodiment, specifically: Two connecting pieces 12 are fixedly installed at the bottom of the anti-collision shell 1. A plurality of expansion bolts 13 for fixing the connecting pieces 12 are installed in both of the two connecting pieces 12. A connecting bar 14 is slidably fitted on one side of the anti-collision shell 1. The installation of the connecting bar 14 facilitates connecting two such devices together.

[0026] In this embodiment, specifically: The connecting bar 14 is in an H-shaped structure. A limiting protrusion is provided at the top of the connecting bar 14. The rotating assembly 11 includes a fixed seat 15 fixedly installed on one side of the sliding plate 8 and a rotating column 16 rotatably fitted on the fixed seat 15. When the vehicle impacts on the rotating column 16, the rotating column 16 rotates at this time, and the friction between the device and the vehicle can be reduced at this time.

[0027] In this embodiment, specifically: Circular disc protrusions are provided on one side of both of the two guide rods 9. Hexagonal sockets are provided on both of the two second gears 3. Two first circular holes and second circular holes are provided on the anti-collision shell 1. A communication groove is provided between the two first circular holes and second circular holes. The two first circular holes and second circular holes are respectively located at the bottoms of the two first gears 2 and second gears 3. The provision of the first circular holes and second circular holes facilitates rainwater to flow out from the inside of the device.

[0028] In this embodiment, specifically: Bolts 17 are fixedly installed at the tops of both of the two threaded rods 4. The two bolts 17 respectively penetrate through the two rotating seats 6. Octagonal protrusions corresponding to the two sliding seats 5 are provided at the tops of both of the two threaded rods 4. The installation of the rotating seats 6 facilitates driving the warning post 7 to rotate, so that the snow on the warning post 7 can fall off.

[0029] In this embodiment, specifically: A plurality of rotating protrusions 601 are provided on both of the two rotating seats 6. The warning post 7 is slidably fitted on the upper side of the anti-collision shell 1. The provision of the rotating protrusions 601 facilitates the rotating seats 6 to rotate when blown by the wind.

[0030] When this utility model works: When the device needs to warn the driver, an inner hexagon wrench needs to be inserted into the inside of the second gear 3, and then the inner hexagon wrench is rotated. At this time, the second gear 3 rotates. The rotation of the second gear 3 drives the first gear 2 to rotate. At this time, the threaded rod 4 rises. At this time, the threaded rod 4 drives the sliding seat 5, the rotating seat 6, and the warning post 7 to rise. When the warning post 7 rises, the warning post 7 warns the driver at this time;

[0031] When the device needs to reduce the degree of damage to the device caused by the vehicle, generally, when the vehicle collides with the guardrail, it does not collide vertically, but first rubs against the guardrail and then gradually approaches the guardrail, and finally forms a collision. However, when the vehicle rubs against the device, the rotating assembly 11 rotates at this time. After the vehicle squeezes the rotating assembly 11, the rotating assembly 11 squeezes the sliding plate 8 and the spring 10 at this time. Then the rotating assembly 11 slides backward, thereby reducing the frictional force between the device and the vehicle.

[0032] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
