[0002] Guardrails are safety devices used to define and protect specific areas, preventing people, vehicles, or objects from straying into or falling into hazardous areas, thereby ensuring public and personal safety. They are widely used in construction sites, road edges, bridges, and municipal construction sites, effectively reducing the risk of accidents by providing a physical barrier.

[0003] Current municipal engineering guardrails on the market, such as the "A Municipal Engineering Guardrail" patent disclosed in Patent No. CN221990064U, include support columns, telescopic frames connected between the support columns, fixed plates connected to the telescopic frames, drive mechanisms connected to the fixed plates, connecting plates connected to both ends of the telescopic frames, fixed mechanisms connected between the connecting plates and the support columns, and a travel mechanism connected to the bottoms of the support columns.

DETAILED DESCRIPTION

[0024] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0025] Example: A guardrail for municipal engineering, such as Figure 1-Figure 3 As shown, it includes a protective frame 1, a fixed rod 101, a slider 102, a slide rail 103, an elastic member 104, a first connecting plate 2, a second connecting plate 3 and a torsion spring 4. The top of the protective frame 1 is fixedly connected to two slide rails 103, the slide rails 103 are slidably connected to the slider 102, the slider 102 is fixedly connected to the fixed rod 101, the slide rails 103 and the slider 102 are provided with elastic members 104, and the two ends of the elastic member 104 are respectively connected to the slider 102 and the slide rail 103, wherein one side of the fixed rod 101 is rotatably connected to the first connecting plate 2, and the other side of the fixed rod 101 is rotatably connected to the second connecting plate 3, the first connecting plate 2 and the second connecting plate 3 are movably connected, and the first connecting plate 2 and the second connecting plate 3 are movably connected. A torsion spring 4 is provided at the movable joint of the connecting plate 3. Here, the setting height of the protective frame 1 is lower than the height of the vehicle chassis, so that the probability of the protective frame 1 being hit is low. The protective frame 1 is used to provide height and support for the device. A torsion spring 4 is also provided between the first connecting plate 2 and the second connecting plate 3 and the fixed rod 101. When subjected to opposite impact, the first connecting plate 2 and the second connecting plate 3 rotate in the direction opposite to the impact direction. At this time, the torsion spring 4 provided at the end of the first connecting plate 2 and the second connecting plate 3 is deformed by the external force, and then relies on the resilience of the torsion spring 4 itself to restore the torsion spring 4 to its initial state and drive the first connecting plate 2 and the second connecting plate 3 to restore to their initial position.

[0026] like Figure 4 and Figure 5As shown, the protective frame 1 is internally rotatably connected to a gear set 8, wherein the gear set 8 includes a central axis and two gears symmetrically mounted on the central axis, the central axis of the gear set 8 is rotatably arranged inside the two standing feet at the bottom of the protective frame 1, and a moving wheel 9 is fixedly connected between the two gears of the gear set 8, the standing foot of the protective frame 1 is slidably connected to a second slider 6, one end of the second slider 6 extends into the inside of the standing foot of the protective frame 1 and is fixedly connected to a square frame 801, the rack in the square frame 801 is meshed with the gear in the gear set 8, the standing foot of the protective frame 1 is slidably connected to two first sliders 5, the opposite ends of the two first sliders 5 extend into the inside of the standing foot of the protective frame 1, a connecting frame 7 is rotatably connected between the two first sliders 5, the end of the connecting frame 7 away from the first slider 5 is rotatably connected to the square frame 801, and one of the first sliders 5 is threadedly connected to a threaded rod 10. The threaded rod 10 is arranged on the outside of the foot of the protective frame 1. One end of the threaded rod 10 passes through the protective frame 1 and is rotatably connected to the protective frame 1. Here, the gear set 8 is composed of a central axis and two identical gears. The central axis is fixedly connected to the gear. The mouth frame 801 is composed of a connecting rod and two mouth frames. The connecting rod is fixedly connected to the rack, and each rack in the mouth frame 801 is respectively engaged with each gear of the gear set 8. When the device needs to be moved, the threaded rod 10 can be twisted clockwise to make the first slider 5 slide upward along the thread. The first slider 5 drives the connecting frame 7 to move upward, and the connecting frame 7 drives the mouth frame 801 to move upward, thereby driving the gear set 8 with the mouth frame 801 to rotate outward, and finally driving the moving wheel 9 to rotate outward, so that the moving wheel 9 flips 180 degrees and contacts the ground, and can then be moved by the pushing device.

[0027] like Figure 1 and Figure 6 As shown, solar panels 11 and LED lights 12 are installed on both sides corresponding to each other of the fixed rod 101. The solar panels 11 and the LED lights 12 are electrically connected. Here, through the design of the solar panels 11 and the LED lights 12, they absorb light energy during the day and convert and store it into electrical energy, and power the LED lights 12 when working at night. The LED lights 12 turn on and emit bright light to provide warnings to pedestrians or vehicles and ensure their safety.

[0028] like Figure 1 and Figure 7 As shown, the side of the fixed rod 101 opposite to the second connecting plate 3 is fixedly connected with an insert plate 13, and the side of the fixed rod 101 opposite to the first connecting plate 2 is fixedly connected with a card plate 14. Here, the design of the insert plate 13 and the card plate 14 enables multiple devices to be connected by inserting the insert plate 13 of one device into the card plate 14 of another device, thereby realizing the combined operation of multiple devices, enabling workers to adjust the blocking range of the device according to actual conditions, and improving the flexibility of the device.

[0029] This device is widely used in the construction of municipal engineering. By placing this device, a construction area is divided and an early warning is provided for pedestrians or vehicles to prevent them from approaching, thereby ensuring that municipal engineering is carried out in an orderly manner. During the operation of the device, the device is easily hit by passing vehicles, and the design of the protective frame 1 being lower than the car chassis makes the impact part of the collision device mainly the first connecting plate 2 and the second connecting plate 3 between the two fixed rods 101. When the device is hit by oncoming vehicles, the first connecting plate 2 and the second connecting plate 3 rotate in the direction opposite to the impact direction, and the first connecting plate 2 and the second connecting plate 3 drive the two fixed rods 101 to approach the center. At this time, the torsion spring 4 provided at the end of the first connecting plate 2 and the second connecting plate 3 is deformed by the external force, and then the first connecting plate 2 and the second connecting plate 3 are driven to return to their initial positions by the resilience of the torsion spring 4. The first connecting plate 2 and the second connecting plate 3 push the two fixing rods 101 away from each other, so that the two fixing rods 101 return to their initial positions. In this process, the torsion spring 4 continuously switches between the deformation and restoration states until the external force is consumed, and the torsion spring 4 maintains the restoration state, thereby absorbing and consuming the external force through the torsion spring 4, reducing the influence of the external force on the device, thereby improving the service life of the device.

[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
