DETAILED DESCRIPTION

[0015] Reference Figs. 1-2 The utility model discloses an embodiment is further explained.

[0016] A safety warning fence for road construction comprises an anti-collision board 1 in the shape of a triangular prism, a warning light 2 for warning pedestrians and a power supply 3 electrically connected to the warning light 2 are mounted on the anti-collision board 1, the warning light 2 is arranged at the top end of the anti-collision board 1, the bottom end of the anti-collision board 1 is in contact with the ground, a chamber 101 is formed in the anti-collision board 1, and a filler 102 for increasing the weight of the anti-collision board 1 is arranged in the chamber 101, the filler 102 can be sand, the anti-collision board 1 comprises an anti-collision surface in the shape of a rectangle, a buffer pad 4 is mounted on the anti-collision surface, the surface of the anti-collision board 1 and the surface of the buffer pad 4 are coated with reflective paint, and a caster assembly 5 for facilitating movement is arranged on the anti-collision board 1.

[0017] In use, the anti-collision board 1 is moved by placing the caster 5 in contact with the ground, facilitating the arrangement of the anti-collision board 1 to a designated position on the construction site, so as to isolate the construction site by the safety warning fence, and then the caster 5 is not in contact with the ground, so that the bottom surface of the anti-collision board 1 is in contact with the ground, which is conducive to the stable placement of the anti-collision board 1. The warning light 2 and the reflective paint are arranged to remind vehicles and pedestrians to avoid in advance, thereby reducing the probability of safety accidents. The buffer pad 4 on the anti-collision surface is directed towards the side of the traffic road for normal traffic, which facilitates the buffer pad 4 to reduce the impact force generated when vehicles and pedestrians accidentally collide with the anti-collision board 1, thereby reducing the damage degree of vehicles and pedestrians, and avoiding damage to the anti-collision board 1. In addition, the anti-collision surface is inclined to disperse the impact energy, further reducing the impact force of the collision between vehicles and pedestrians, avoiding damage to vehicles and pedestrians, and reducing the risk of safety accidents. In combination with the fact that the anti-collision board 1 is in the shape of a triangular prism and the filler 102 in the cavity 101 of the anti-collision board 1 increases the overall weight of the anti-collision board 1, the stability of the anti-collision board 1 is increased, the anti-collision board 1 is less likely to collapse due to collision, the impact resistance is improved, the ability of the safety warning fence to withstand external impact is improved, the safety warning fence is less likely to be damaged or even collapsed when colliding with vehicles and pedestrians, the damage to vehicles and pedestrians is reduced, and the risk of safety accidents is reduced.

[0018] The buffer pad 4 includes a fixed plate 401 detachably connected to the anti-collision board 1 and an elastic rubber plate 402 mounted on the fixed plate 401. The elastic rubber plate 402 cooperates with the fixed plate 401 to form a sealed hollow chamber 403101. An elastic rubber block 404 is arranged in the hollow chamber 403101. The two ends of the elastic rubber block 404 are connected to the fixed plate 401 and the elastic rubber plate 402, respectively.

[0019] When the elastic rubber plate 402 is impacted, it will deform to absorb and disperse the impact force generated by the impact. In combination with the existence of the hollow chamber 403101 in the buffer pad 4, the impact force can be dispersed in a larger range when the elastic rubber plate 402 is impacted, thereby reducing the impact force per unit area and reducing the damage to the elastic rubber plate 402 and its fixed plate 401, and further avoiding damage to the anti-collision board 1. In the process of impact, the air in the hollow chamber 403101 is compressed, which further increases the impact absorbing capacity of the buffer pad 4. The arrangement of the elastic rubber block 404 makes the impact resistance of the elastic rubber plate 402 stronger, thereby reducing the impact force generated when vehicles and pedestrians accidentally collide with the anti-collision board 1, reducing the damage degree of vehicles and pedestrians, reducing the severity of safety accidents, and avoiding damage to the anti-collision board 1.

[0020] The fixed plate 401 is provided with a plug-in block 4011, and the anti-collision plate 1 is provided with a plug-in hole 103 for plugging with the plug-in block 4011. The plug-in connection between the plug-in block 4011 on the fixed plate 401 and the plug-in hole 103 on the anti-collision plate 1 can realize the detachable connection of the buffer pad 4 on the anti-collision plate 1, so that the anti-collision plate 1 can be continuously used after the buffer pad 4 is replaced when the buffer pad 4 is damaged, and the practicability is improved.

[0021] The caster 5 comprises a connecting rod 501 mounted on the anti-collision plate 1, a supporting rod 502 mounted on the connecting rod 501, and a caster 503 rotatably connected to the supporting rod 502. The connecting rod 501 is provided with a threaded pipe 504, one end of the supporting rod 502 is rotatably connected to the threaded pipe 504, and the caster 503 is rotatably connected to the other end of the supporting rod 502. When the anti-collision plate 1 needs to be moved, the supporting rod 502 is rotated to be screwed with the threaded pipe 504, so that the caster 503 at the other end of the supporting rod 502 is in contact with the ground, thereby achieving the purpose of moving the anti-collision plate 1 to a designated position through the caster 5 and making the caster 503 not in contact with the ground after being moved to the designated position, so that the anti-collision plate 1 can be stably placed.

[0022] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. Any common change and replacement within the technical scheme of the present application should be included in the protection scope of the present application.
