However, most of the existing safety warning devices are fixed and cannot be moved. At the same time, the fixed structure of the safety warning devices cannot be retracted or adjusted when not in use. Therefore, improvements are needed to address the above problems. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional safety warning device for construction sites, comprising two bases, with a square hollow tube fixedly installed at the center of the top of each of the two bases, a lifting rod movably inserted into the top of each of the two square hollow tubes, and a square slider slidably installed inside each of the two square hollow tubes. The bottom of each of the two lifting rods is fixedly connected to the top of each of the two square sliders, and a fixing component is provided on the upper part of each of the two square hollow tubes to limit the movement of the square sliders. Four safety information sticker warning plates are provided between the two lifting rods. The tops and bottoms of any two adjacent safety information sticker warning plates are rotatably connected by a connecting shaft and a connecting block. The tops of the two safety information sticker warning plates on the side closest to the lifting rods are rotatably connected to the tops of the two lifting rods by a movable shaft and a connecting block. Leveling components are installed at both ends of the two bases, and stabilizing reinforcement components are installed on one side of each of the two bases.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Depend on Figures 1 to 4 The present invention includes two bases 1, with a square hollow tube 2 fixedly installed at the center of the top of each base 1. A lifting rod 3 is movably inserted into the top of each square hollow tube 2. A square slider 8 is slidably installed inside each square hollow tube 2. The bottom of each lifting rod 3 is fixedly connected to the top of each square slider 8. A fixing piece 4 is provided on the upper part of each square hollow tube 2 to limit the square slider 8. Four safety information sticker warning plates 5 are provided between the two lifting rods 3. The tops and bottoms of any two adjacent safety information sticker warning plates 5 are rotatably connected by a connecting shaft and a connecting block. The tops of the two safety information sticker warning plates 5 located on both sides near the lifting rod 3 are rotatably connected to the tops of the two lifting rods 3 by a movable shaft and a connecting block, so that the four safety information sticker warning plates 5 can be folded and unfolded for adjustment. A leveling piece 6 is installed at both ends of each base 1, and a stabilizing reinforcement piece 7 is installed on one side of each base 1.

[0017] Each of the two square sliders 8 has a limit hole 9 on one side. A spring 10 is fixedly installed on the upper part of each of the two square hollow tubes 2. A circular plate 11 is fixedly connected to the end of the spring 10 away from the square hollow tube 2. A pin 12 located in the middle of the spring 10 is fixedly installed on one side of the circular plate 11. The pin 12 moves through the square hollow tube 2 and is inserted into the limit hole 9. A pull handle 13 is fixedly installed on the side of the circular plate 11 away from the spring 10, so that the lifting and lowering can be effectively adjusted.

[0018] Specifically, by pulling the two handles 13, the circular plate 11 moves the pin 12 and stretches the spring 10, causing the pin 12 to retract from the limiting hole 9. At this time, the square slider 8 loses the limitation of the pin 12, causing the square slider 8 to move the lifting rod 3 downward inside the square hollow tube 2. The downward movement of the two lifting rods 3 will cause the four safety information sticker warning plates 5 to move downward, so that the four safety information sticker warning plates 5 move down between the two square hollow tubes 2. Then, the two bases 1 and the two square hollow tubes 2 are moved relative to each other, and finally the four safety information sticker warning plates 5 are folded and retracted. The above adjustment effectively retracts and adjusts the safety warning device.

[0019] Each of the four leveling components 6 includes a first threaded shaft 14, which is threadedly connected to both ends of the two bases 1. A first rotating wheel 15 is fixedly installed on the top of the first threaded shaft 14, and a base plate 16 for supporting the leveling is fixedly installed on the bottom of the first threaded shaft 14. This allows for effective adjustment when the ground is uneven, ensuring the display of the safety warning device. By rotating the first rotating wheel 15, the first threaded shaft 14 is rotated and moved downward. The rotation and downward movement of the first threaded shaft 14 will drive the base plate 16 to move downward, thus providing support and leveling.

[0020] Both stabilizing reinforcement components 7 include a cylindrical tube 17 fixedly installed on the top of the two bases 1. The bottom of the cylindrical tube 17 is open and penetrates through the base 1. The inside of the cylindrical tube 17 is equipped with a spiral fan-blade drilling shaft 18. The top of the cylindrical tube 17 is threadedly connected to a second threaded shaft 19. The bottom of the second threaded shaft 19 is fixedly connected to the top of the spiral fan-blade drilling shaft 18, and a second rotating wheel 20 is fixedly installed on the top of the second threaded shaft 19. This effectively enables drilling and fixing, ensuring the stability and firmness of the safety warning device. When the device is unfolded and the four safety information sticker warning boards 5 are unfolded on a plane, rotating the second rotating wheel 20 causes the second threaded shaft 19 to rotate and move downward. The rotation and downward movement of the second threaded shaft 19 will drive the spiral fan-blade drilling shaft 18 to rotate and move downward, thereby causing the spiral fan-blade drilling shaft 18 to drill into the soil, maintaining the stability, safety, and firmness of the device when it is unfolded.

[0021] This construction site safety warning device features a foldable and retractable design for easy transport and movement. It also includes a leveling and fixing structure. The folding and retracting design reduces storage space, while the ease of transport and movement enhances the device's flexibility. The leveling and fixing structure effectively improves the device's stability and safety. Furthermore, this safety warning device has a simple structural design, is convenient to use and operate, and is stable and reliable in adjustment and fixing. Its performance meets the needs of multiple applications.
