[0002] Traffic guardrails are a kind of traffic safety facilities set up at the outer side of the shoulder, traffic separation strips and pedestrian curbs, etc., which absorb collision energy by self-deformation or vehicle climbing, thereby changing the direction of vehicle travel, preventing vehicles from going out of the road or entering the opposite lane, and minimizing the damage to passengers. The functions of traffic guardrails are: first, preventing vehicles from rushing out of the road and causing rollover accidents, especially traffic guardrails set up in mountain bends and dangerous roads. For motor vehicle drivers, they can attract full attention from a distance, making them more vigilant, and can also guide the driver's line of sight when passing, helping them to operate correctly; second, it can prevent the oncoming vehicle from having a head-on collision, and at the same time prevent the same-direction vehicle from rubbing or hanging; third, it can prevent vehicles from hitting pedestrians, and prevent pedestrians from crossing the road at will, etc. The fences and columns of existing traffic guardrails are mostly connected by bolts. Due to the large number of bolts, disassembly and assembly are more complicated, which makes it difficult to assemble quickly, reducing the efficiency of assembly. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 A fast-assembly traffic guardrail comprises a plurality of posts 1, and a fence 4 is arranged between each two adjacent posts 1. The outer surface of the fence 4 is coated with reflective paint, which serves to remind vehicles in dim light. Two groups of sockets 6 are relatively opened on both sides of the posts 1 connecting the fence 4, and a plug rod 13 is connected. The two groups of sockets 6 are arranged at intervals along the vertical direction. A threaded rod 7 is rotatably arranged between the two sockets 6 of each group, and the two ends of the threaded rod 7 extend into the two sockets 6 respectively. A worm 2 is vertically rotatably arranged in the post 1, and the upper end of the worm 2 extends to the outside of the post 1. A rotating handle 14 is fixedly arranged on the top of the worm 2 to facilitate the rotation of the worm 2. The outer surface of the threaded rod 7 is sleeved with a turbine 8 meshing with the worm 2. The sockets 6 correspond to the two ends of the guardrail. A plug rod 13 is provided, and a threaded hole matching the threaded rod 7 is opened on one side of the plug rod 13. During assembly, the plug rods 13 on the fences 4 on both sides of the column 1 are respectively inserted into the sockets 6, and the worm gear 2 is rotated to drive the turbine 8 to rotate, and the turbine 8 drives the threaded rod 7 to rotate. At the same time, a certain pressure is applied to the fence 4 in the direction of the threaded rod 7, so that the plug rod 13 moves in the direction of the threaded rod 7 as the threaded rod 7 rotates, until the threaded rod 7 located in the socket 6 completely enters the threaded hole on the plug rod 13, thereby completing the connection between the column 1 and the fence 4. Since the rotation of the worm gear 2 can connect the four sockets 6 with the plug rod 13 at the same time, that is, the fences 4 on both sides of the column 1 are connected to the column 1 at the same time, the column 1 and the fence 4 can be quickly assembled, thereby improving the assembly efficiency.

[0020] Specifically, a slide groove 9 is respectively provided inside the two sides of the fence 4, and a plug rod 13 is slidably arranged in the slide groove 9, and a spring 12 is arranged between the plug rod 13 and the slide groove 9, and a guide groove 10 is provided on the inner side wall of the slide groove 9, and a guide block 11 is slidably arranged in the guide groove 10, and one side of the guide block 11 is fixedly connected with the plug rod 13. Because when the worm 2 rotates, the fence 4 needs to drive the plug rod 13 to move in the direction of the threaded rod 7 so that the threaded hole on the plug rod 13 can be smoothly connected with the threaded rod 7. Therefore, when assembling, the plug rod 13 can be directly moved along the slide groove 9 in the direction away from the socket 6 until the guide block 11 moves along the guide groove 10 to the end away from the socket 6. At this time, the spring 12 is compressed, and then the worm 2 is rotated. Under the restoring force of the spring 12, the threaded hole on the plug rod 13 can be smoothly connected with the threaded rod 7. Therefore, when the worm 2 rotates, there is no need to make the fence 4 continue to move in the direction of the threaded rod 7, saving manpower.

[0021] Specifically, the sliding distance of the guide block 11 is equal to the length of the threaded hole, ensuring that after the threaded hole is connected to the threaded rod 7, the fence 4 and the column 1 will not be loose.

[0022] Specifically, the upper end and the lower end of the column 1 are respectively provided with a waterproof cover 3 and a support foot 5. The waterproof cover 3 prevents rainwater from entering the interior of the column 1 and protects the internal structure. The support foot 5 improves the stability of the column.

[0023] In another embodiment, after the traffic guardrail is assembled according to the required length of the road, since sockets 6 are opened on both sides of the column 1, two sockets 6 are exposed to the outside on one side of the column 1 at both ends of the traffic guardrail. Therefore, a cover body matching the opening of the socket 6 can be used to be threadedly connected to the column 1 to prevent dust and other impurities from entering the internal structure of the column 1 and protect the internal structure of the column 1.

[0024] The working principle of a fast-assembly traffic guardrail provided by the utility model is as follows: during assembly, the insertion rods 13 on the fences 4 on both sides of the column 1 are respectively inserted into the sockets 6, so that the insertion rods 13 move along the slide groove 9 in the direction away from the socket 6 until the guide block 11 moves along the guide groove 10 to the end away from the socket 6. At this time, the spring 12 is compressed, and the rotating worm 2 drives the turbine 8 to rotate, and the turbine 8 drives the threaded rod 7 to rotate. At the same time, under the restoring force of the spring 12, the insertion rod 13 moves in the direction of the threaded rod 7 as the threaded rod 7 rotates, until the threaded rod 7 located in the socket 6 completely enters the threaded hole on the insertion rod 13, thereby completing the connection between the column 1 and the fence 4. Since the rotation of the worm gear 2 can simultaneously connect the four sockets 6 with the insertion rod 13, that is, the fences 4 on both sides of the column 1 are connected to the column 1 at the same time, the column 1 and the fence 4 can be quickly assembled, thereby improving the assembly efficiency.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
