[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5The temporary guardrail for road maintenance shown includes a support plate 1, a connecting plate 2 at the top of the support plate 1, connecting rods 3 slidably sleeved inside both ends of the support plate 1, a marker strip 6 at the top center of the support plate 1, clips 4 on both sides of the marker strip 6, and support rods 5 at both bottom ends of the support plate 1; a rectangular hole 101 is opened at the center of the support plate 1, a lead screw 501 is fixedly installed at the top center of the support rod 5, and a nut 502 is rotatably connected to the outer wall of the lead screw 501; a sliding hole 201 is opened at the center of the connecting plate 2, a sliding block 202 is slidably connected inside the sliding hole 201, and through holes corresponding to the connecting rods 3 are opened at both ends of the connecting plate 2; a clip plate 601 is provided at both ends of the marker strip 6, the bottom of the clip 4 is rotatably connected to the clip plate 601, and a moving block 401 is slidably connected to one side of the top of the clip 4.

[0028] The support plate 1 and connecting plate 2 can be easily moved to the positions of the rotating rods 301 at both ends of the connecting rod 3. Since the connecting rod 3 is rotatably connected to the rotating rod 301, the support plate 1 and connecting plate 2 are rotatably connected to the connecting rod 3 via the rotating rod 301. This allows the support plate 1 and connecting plate 2 to form a parallelogram with the connecting rod 3. The connecting plate 2 can be easily rotated and moved towards the support plate 1 at the bottom for storage. The position of the snap-fit ​​plate 601 can be adjusted by the sliding block 202, thereby adjusting the position of the label strip 6. The distance between the two sliding blocks 202 can also be adjusted according to the length of the label strip 6, thus adjusting the distance between the snap-fit ​​plates 601. This allows for easy adjustment according to usage requirements. The moving block 401 can also be easily adjusted towards the bottom during installation.

[0029] like Figure 4 , Figure 5 As shown, a groove corresponding to the height of the label strip 6 is provided on one side of the snap-fit ​​plate 601. The bottom of the snap-fit ​​strip 4 is rotatably connected to the bottom of the groove of the snap-fit ​​plate 601 via a pivot. A slot corresponding to the moving block 401 is provided at the top of the groove. A magnet block 602 is fixedly connected to the bottom of the snap-fit ​​plate 601. A sliding groove is provided on the top of the snap-fit ​​strip 4 near the moving block 401. The moving block 401 is slidably connected to the sliding groove. A compression spring 402 is fixedly connected to the end of the moving block 401 near the snap-fit ​​strip 4. The bottom end of the compression spring 402 is fixedly connected to the snap-fit ​​strip 4, so that the magnet block 602 at the bottom of the snap-fit ​​plate 601 is attracted and fixed to the support plate 1, thereby realizing the installation of the label strip 6 and thus realizing the installation of the entire device. Since the snap-fit ​​plate 601 and the sliding block 202 are rotatably connected via a ball joint, the snap-fit ​​plate 601 can also be easily rotated and stored, thereby reducing the storage volume of the entire device.

[0030] like Figure 2 , Figure 3As shown, the top and bottom of the connecting rod 3 are rotatably connected to a rotating rod 301. The diameter of the rotating rod 301 is the same as that of the connecting rod 3. Both ends of the connecting rod 3 are rotatably connected to the rotating rod 301 via a rotating shaft. The bottom of the sliding block 202 is rotatably connected to the top of the snap-fit ​​plate 601 via a ball joint. Both ends of the connecting plate 2 are threaded with fixing bolts 203, and one end of the fixing bolt 203 penetrates the interior of the connecting plate 2 and is pressed against the connecting rod 3. This allows the support plate 1 and the connecting plate 2 to be moved to the positions of the rotating rods 301 at both ends of the connecting rod 3. At the same time, since the connecting rod 3 is rotatably connected to the rotating rod 301, the support plate 1 and the connecting plate 2 are rotatably connected to the connecting rod 3 via the rotating rod 301. This allows the support plate 1 and the connecting plate 2 to form a parallelogram with the connecting rod 3. This makes it easy to rotate and move the connecting plate 2 towards the bottom and closer to the support plate 1, thus achieving storage.

[0031] like Figure 1 , Figure 2 As shown, both ends of the support rod 5 are bent downwards and in contact with the ground. The top of the support rod 5 is in contact with the bottom of the support plate 1. The bottom of the outer wall of the nut 502 is pressed against the top of the support plate 1. The position of the top screw 501 of the support rod 5 is adjusted, and then the nut 502 is rotated so that the nut 502 rotates closer to the support plate 1. Thus, the top and bottom of the support plate 1 are respectively fixed to the bottom of the nut 502 and the top of the support rod 5, which can realize the adjustment and installation of the support rod 5 to meet different usage requirements.

[0032] During use, the device can be easily moved to the desired road location. Simultaneously, the support plate 1 and connecting plate 2 can be moved towards the center of the connecting rod 3, allowing both support plate 1 and connecting plate 2 to slide and engage with the connecting rod 3. The fixing bolt 203 can then be rotated to press and fix the connecting rod 3, thus securing the connecting plate 2 to the connecting rod 3. This allows the support plate 1 to achieve a rectangular fixed connection with the connecting plate 2 via the connecting sleeve 3, preventing the support plate 1 from tilting or falling over. This facilitates convenient and quick assembly. Furthermore, the magnet 602 at the bottom of the snap-fit ​​plate 601 is attracted and fixed to the support plate 1, enabling the installation of the marking strip 6. When installing and storing the entire device, the support plate 1 and connecting plate 2 can be easily moved to the rotating rods 301 at both ends of the connecting rod 3. Since the connecting rod 3 is rotatably connected to the rotating rod 301, both the support plate 1 and the connecting plate 2 are rotatably connected to the connecting rod 3 via the rotating rod 301. This allows the support plate 1 and the connecting plate 2 to form a parallelogram with the connecting rod 3, making it easy to rotate and move the connecting plate 2 towards the bottom and close to the support plate 1 for storage. At the same time, since the snap-fit ​​plate 601 and the sliding block 202 are rotatably connected via a ball joint, the snap-fit ​​plate 601 can also be easily rotated and stored, thus reducing the overall storage volume of the device.

[0033] During use, the height of the connecting plate 2 can be easily adjusted as needed, thereby adjusting the position of the snap-fit ​​plate 601 via the sliding block 202, and thus adjusting the position of the marking strip 6. The distance between the two sliding blocks 202 can also be adjusted according to the length of the marking strip 6, allowing for easy adjustment based on usage requirements. During installation, the moving block 401 can be easily adjusted downwards to release the snap-fit ​​between the moving block 401 and the snap-fit ​​plate 601. Then, rotating the snap-fit ​​strip 4 allows the marking strip 6 to be easily placed inside the snap-fit ​​plate 601. Furthermore, the position of the top screw 501 of the support rod 5 can be adjusted as needed, and rotating the nut 502 causes it to rotate closer to the support plate 1. This allows the top and bottom of the support plate 1 to be fixed in place with the bottom of the nut 502 and the top of the support rod 5, respectively, enabling the adjustment and installation of the support rod 5 to meet different usage requirements.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
