Description

Technical Field

[0001] The utility model belongs to the technical field of guardrails, in particular to a road guardrail. Background Art

[0002] Guardrails, also known as fences, are railings installed to avoid danger or block traffic. They are divided into industrial fences (such as factory fences and commercial site fences), agricultural fences (such as field fences and livestock fences), civil fences (such as building roof fences and fence walls), public facility fences (such as road barriers), etc. Fences generally include a guardrail body and posts. The guardrail body is generally composed of several vertical bars and horizontal bars. The guardrail body is located between two posts, and the posts are fixed to the ground. It is a simple support structure with a relatively thin and overly simple structure, which can only play a simple isolation role. When the guardrail is impacted, these simple support structures come into contact with the impacting object and generate a large impact force. These structures are usually made of plastic or aluminum and cannot absorb the impact force. The huge impact force can easily damage the guardrail and cannot effectively block the impacting object. Such road guardrails are relatively simple in structure and have poor protection effect. When they encounter impact, they are easily damaged and are not convenient for blocking.

An anti-collision component is connected between the two cross bars, and the anti-collision component includes a rotating shaft rotatably installed between the two cross bars, a buffer sleeve is provided on the outside of the rotating shaft, and gears are provided on both sides of the outside of the rotating shaft.

[0006] Preferably, one end of the pulling plate is connected to a pressing plate, both sides of one end of the pressing plate are connected to telescopic damping rods, and one end of the telescopic damping rod is connected to one side of the fixing plate.

[0007] Preferably, a buffer spring is sleeved on one side of the exterior of the telescopic damping rod, one end of the buffer spring is connected to one side of the fixing plate, and the other end of the buffer spring is connected to one side of the pressure plate.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The utility model provides an anti-collision component, so that the buffer sleeve is deformed under pressure and absorbs part of the impact force. The buffer sleeve rotates to change the trajectory of the impact object. At the same time, the rotating shaft drives the gear to rotate. Under the meshing transmission of the gear and the tooth plate, the buffer spring and the telescopic damping rod on one side of the tooth plate are in a contracted state, and the buffer spring and the telescopic damping rod on the other side of the tooth plate are in a stretched state, so that the buffer spring is deformed and absorbs the energy generated by the impact, thereby better protecting the guardrail and the impact object.

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-4 This application is described in further detail.

[0019] The embodiment of the present application discloses a road guardrail. Figure 1-2 , including a column 1, a cross bar 2 is opened on both sides of one end of the column 1, there are two cross bars 2, an anti-collision component 3 is connected between the two cross bars 2, and the anti-collision component 3 includes a rotating shaft 31 rotatably installed between the two cross bars 2, and both ends of the rotating shaft 31 are rotatably connected to the inner walls of the two cross bars 2 through bearings, so that the rotating shaft 31 can drive the buffer sleeve 32 to rotate. The outer side of the rotating shaft 31 is provided with a buffer sleeve 32, and the buffer sleeve 32 is made of polyurethane material, which mainly plays a buffering role. When a vehicle hits the guardrail, polyurethane can rely on its own elastic deformation to absorb energy. When the buffer sleeve 32 is subjected to external impact, it effectively absorbs the impact force generated. Gears 33 are provided on both sides of the outer side of the rotating shaft 31.

[0020] Reference Figure 3 , a toothed plate 34 is engaged with one side of the gear 33, and the gear 33 is meshed with the toothed plate 34. The rotation of the gear 33 drives the toothed plate 34 to move. The gear 33 and the toothed plate 34 have a transmission guiding function. One end of the toothed plate 34 is slidably connected to one side of the inner wall of the cross bar 2. Pull plates 35 are connected to both sides of the toothed plate 34. The pull plates 35 are slidably connected to the fixed plates 36. The movement of the pull plates 35 will not drive the fixed plates 36 to move. A fixed plate 36 is sleeved on one side of the outer side of the pull plate 35. The fixed plate 36 installs and supports the telescopic damping rod 38 and the buffer spring 39, so that the buffer spring 39 and the telescopic damping rod 38 can be installed. The damping rod 38 contracts under the pressure of the pressure plate 37, the fixed plate 36 is fixedly connected to the inner wall of the cross bar 2, one end of the pull plate 35 is connected to the pressure plate 37, and telescopic damping rods 38 are connected on both sides of one end of the pressure plate 37. One end of the telescopic damping rod 38 is connected to one side of the fixed plate 36, and a buffer spring 39 is sleeved on one side of the outside of the telescopic damping rod 38. The buffer spring 39 contracts under the pressure of the pressure plate 37 and then deforms to absorb part of the impact force. One end of the buffer spring 39 is connected to one side of the fixed plate 36, and the other end of the buffer spring 39 is connected to one side of the pressure plate 37.

[0021] Reference Figure 4 , both sides of one end of the column 1 are connected to the card seat 4, and one side of the card seat 4 is connected to the connecting block 5. Insert the connecting block 5 into the card seat 4 so that the connecting block 5 and the card seat 4 are plugged in. One end of the connecting block 5 is connected to one side of the cross bar 2, and one end of the connecting block 5 extends through to the inside of the card seat 4. A threaded groove 6 is opened in the middle of one side of the connecting block 5, and a threaded rod 7 is threadedly connected to one side of the threaded groove 6. Rotate the threaded rod 7 to move the threaded rod 7 into the inside of the threaded groove 6, so that the connecting block 5 and the card seat 4 are fixedly connected, and one end of the threaded rod 7 extends through to the outside of the card seat 4.

[0022] The implementation principle of a road guardrail in an embodiment of the present application is as follows: during use, when the column 1 and the crossbar 2 are subjected to external impact, the buffer sleeve 32 is compressed and deformed to absorb part of the impact force. At the same time, after the buffer sleeve 32 bears the impact force, it drives the rotating shaft 31 to rotate. The rotation of the buffer sleeve 32 changes the trajectory of the impact object and returns to the normal driving direction, preventing the impact object from breaking through the guardrail and causing a secondary collision, thereby causing a more serious accident. At the same time, the rotating shaft 31 drives the gear 33 to rotate. Because the gear 33 is meshed with the tooth plate 34, the rotation of the gear 33 drives the tooth plate 34 to move to one side, the tooth plate 34 drives the pull plate 35 to move, and the pull plate 35 drives the pressure plate 37 to move. Because the pull plates 35 are connected to both sides of the tooth plate 34, under the pull of the pull plates 35, the buffer spring 39 and the telescopic damping rod 38 on one side of the tooth plate 34 are in a contracted state, and the buffer spring 39 and the telescopic damping rod 38 on the other side of the tooth plate 34 are in a stretched state, causing the buffer spring 39 to deform and absorb the energy generated by the impact, thereby better protecting the guardrail and the impact object.
