[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] A type of warning barrier for construction sites, such as Figure 1 , 2As shown in Figures 3, 4, and 5, the system includes a base 1, on which a first baffle 2 is provided, and on which a second baffle 3 is provided. The first baffle 2 is slidably mounted on the base 1. Several first dovetail grooves 4 are formed on the top of the base 1. Several first dovetail sliders 5 are fixedly mounted on the bottom of the first baffle 2 corresponding to the first dovetail grooves 4. The first dovetail sliders 5 are slidably mounted within their respective first dovetail grooves 4. The second baffle 3 is hinged to the top of the first baffle 2. The left sides of the first baffle 2 and the corresponding second baffle 3 that are close to each other are hinged together by a hinge shaft. One side of the second baffle 3 is... The second dovetail slider 7 is fixedly installed. Second dovetail grooves 8 are respectively opened on the other side of the second baffle 3. The second dovetail slider 7 is fixedly installed on the right side of the second baffle 3, and the second dovetail grooves 8 are respectively opened on the left side of the second baffle 3. The second dovetail slider 7 is slidably installed within the second dovetail grooves 8 on the adjacent second baffle 3. A third dovetail groove 9 is opened on the same side of the first baffle 2 as the side where the second dovetail slider 7 is fixedly installed on the second baffle 3. A third dovetail groove 9 is also opened on the right side of the first baffle 2. The front sides of the first dovetail groove 4, the second dovetail slider 7, and the third dovetail groove 9 are respectively connected to the outside. This utility model has a simple structure and ingenious design. The length of the warning barrier can be changed by the sliding connection of the second dovetail slider 7 and the second dovetail slider 8. Rotating the second baffle 3 180 degrees along the hinge axis of the first baffle 2 and the second baffle 3 can change the height of the warning barrier, which can meet market demand and is suitable for promotion.When using this utility model, the base 1 is installed at a designated position on the ground. The first dovetail slider 5 is slidably installed in the first dovetail groove 4 on the base 1, thereby installing the first baffle 2 on the base 1. The second baffle 3 is located above the first baffle 2. When it is necessary to extend the length of the warning barrier, another base 1 is placed horizontally aligned with the already installed base 1, with the two base 1s close to each other on their adjacent sides. The first dovetail slider 5 on the second first baffle 2 is aligned with the first dovetail groove 4 on the second base 1, and the second dovetail groove 8 on the second second baffle 3 is aligned with the second dovetail slider 7 on the first second baffle 3. Then, the second first baffle 2 and the second baffle 3 are moved backward, so that the first dovetail slider 5 is slidably installed in the corresponding first dovetail groove 4, and the second dovetail slider 7 is slidably installed in the second dovetail groove 8. Thus, the base 1, the first baffle 2, and the second baffle 3 can be spliced ​​together according to the required length of the warning barrier. When splicing, make sure that... The rear sides of the first baffle 2 and the second baffle 3 face the outside of the construction site, allowing warning signs and slogans to be affixed to the plane formed by the splicing of the first baffle 2 and the second baffle 3. When the height of the warning barrier needs to be changed, the second baffle 3 is rotated 180 degrees counterclockwise along the hinge axis between the first baffle 2 and the second baffle 3, so that the second baffle 3 is located to the left of the corresponding first baffle 2. The first base 1 is then fixedly installed on the ground. The first baffle 2 is then slidably installed on the base 1 through the first dovetail groove 4 and the first dovetail slider 5. The other second baffle 3 is rotated in the same manner, and the second dovetail slider 7 on the second second baffle 3 is slidably installed in the third dovetail groove 9 on the first first baffle 2. The first dovetail slider 5 on the second first baffle 2 is slidably installed in the first dovetail groove 4 on the second base 1. The second base 1 is then fixedly installed on the ground. At this time, the height of the warning barrier becomes half of its original height. The warning barrier can be spliced ​​as needed according to the required length.

[0018] Specifically, as shown in the figure, in this embodiment, the first baffle 2 and the second baffle 3 have clearance grooves 20 on the side away from the corresponding hinge axis. The front and right sides of the clearance grooves 20, as well as the sides of the two vertically aligned clearance grooves 20 that are close to each other, are respectively connected to the outside. The hinge axis is located in the adjacent clearance groove 20. The fact that the hinge axis is located in the corresponding clearance groove 20 can ensure that the surfaces of the first baffle 2 and the second baffle 3 are flat and can prevent the hinge axis from interfering with the adjacent first baffle 2 and the second baffle 3.

[0019] Specifically, as shown in the figure, nuts 30 are fixedly installed on the left and right sides of the front side of the base 1 in this embodiment. The two nuts 30 on two adjacent bases 1 are threaded together with the same screw 31. When the screw 31 is turned in the forward direction, it engages with the two adjacent nuts 30 on the two adjacent bases 1. At this time, the screw 31 limits the two adjacent bases 1 and prevents relative movement between the two adjacent bases 1. Similarly, when the screw 31 is turned in the reverse direction, it no longer blocks one of the bases 1. At this time, the two bases 1 can move relative to each other.

[0020] Furthermore, as shown in the figure, in this embodiment, rings 40 are fixedly installed on the front side of the base 1 and the front side of the first baffle 2, respectively. The rings 40 on the base 1 are aligned with the corresponding rings 40 on the first baffle 2. Insert rods 41 are slidably installed inside the rings 40 on the first baffle 2. The insert rods 41 are connected to the corresponding rings 40 by springs 42. The springs 42 are fitted around the outer circumference of the corresponding insert rods 41. One end of the springs 42 is fixedly connected to the outer circumference of the corresponding insert rods 41, and the other end of the springs 42 is fixedly connected to one side of the corresponding rings 40. Under the elastic force of the springs 42, the insert rods 41 are slidably installed inside the corresponding rings 40 on the base 1. The insert rods 41 and the two corresponding rings 40 are coaxially arranged. Pull the insert rod 41 upwards, and the spring 42 extends until the lower end of the insert rod 41 moves out of the ring 40 on the corresponding base 1. At this time, the insert rod 41 no longer limits the corresponding base 1 and the first baffle 2, and the first baffle 2 can slide forward relative to the corresponding base 1. When it is necessary to limit the base 1 and the corresponding first baffle 2, slide the first baffle 2 so that the ring 40 on the first baffle 2 is aligned with the ring 40 on the corresponding base 1. At this time, under the elastic force of the spring 42, the insert rod 41 moves downwards and slides to connect with the ring 40 on the corresponding base 1.

[0021] Furthermore, as shown in the figure, baffles 50 are fixedly installed on the upper end of the insertion rod 41 in this embodiment. Pulling the insertion rod 41 through the baffles 50 is more convenient and less strenuous.

[0022] Furthermore, as shown in the figure, reflective warning strips 60 are affixed to the rear side of the base 1 and the upper end of the rear side of the second baffle 3 in this embodiment. Under poor lighting conditions at night, when light shines on the reflective warning strips 60, the reflective warning strips 60 can reflect light, thus serving as a warning to passing vehicles and pedestrians.

[0023] Furthermore, as shown in the figure, the base 1 in this embodiment has several mounting holes 70. The mounting holes 70 facilitate the fixing of the base 1 to the ground.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
