Technical Field

[0001] The utility model relates to the field of public facility maintenance equipment, and more specifically, to a barrier for public facility maintenance. Background Art

[0002] When maintaining public facilities such as roads, bridges, parks, etc., it is usually necessary to set up barriers to warn pedestrians and vehicles to ensure the safety of the construction area. However, most of the existing barriers are of fixed or integral design, which are not convenient for quick installation and disassembly, and lack the flexibility to adapt to different sites and requirements. Summary of the Utility Model

[0003] Based on the above technical problems, the utility model provides a barrier for public facility maintenance.

[0004] A barrier for public facility maintenance includes: support columns and a guardrail frame. The two ends of the guardrail frame are detachably installed on the two support columns. A support base is provided at the lower end of the support column. Through holes are provided at both ends of the support base, and pin nails are provided at the through holes. Vertical grooves are formed inside the support columns. Slots are provided at the bottoms of the vertical grooves. Sliders are provided at the upper parts of the vertical grooves. The sliders are slidably installed in the vertical grooves. Insertion rods are provided at the lower sides of the sliders. Springs are provided between the upper sides of the sliders and the tops of the vertical grooves. One installation rod is provided at each end of the guardrail frame. Grooves matching the insertion rods are provided at the upper ends of the installation rods. Short rods matching the slots are provided at the lower ends of the installation rods.

[0005] Preferably, the guardrail frame is composed of cross bars, vertical bars, and isolation bars. The cross bars and the vertical bars are connected end to end to form a rectangular frame. A plurality of isolation bars are arranged between the vertical bars. The isolation bars are perpendicular to the vertical bars. Warning plates are provided in the middle of the isolation bars. Reflective layers are coated on both sides of the warning plates.

[0006] Preferably, the support base is a U-shaped seat, and support feet are provided at both ends thereof. The through holes pass through the support feet.

[0007] Advantageous Effects

[0008] 1. Through the design of the insertion rods and slots, the guardrail frame can be quickly installed on or disassembled from the support columns, facilitating rapid deployment and evacuation during construction.

[0009] 2. The design of the pin nails on the support base enables the barrier to be firmly fixed on the muddy ground, improving the protection effect of the guardrail.

[0010] 3. The design of the reflective layers and warning plates on the guardrail frame enhances the warning effect at night or under low light conditions, ensuring the safety of the construction area. Brief Description of the Drawings

[0014] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0015] In this embodiment, as Figures 1 to 3 shown, a barrier for public facility maintenance includes a support column 2 and a guardrail frame 3. The two ends of the guardrail frame 3 are detachably installed on the two support columns 2. A support base 1 is provided at the lower end of the support column 2. Through holes 4 are provided at both ends of the support base 1. A pin 5 is provided at the through hole 4. On some relatively soft ground, the support base 1 can be firmly fixed to the ground by driving the pin 5 into the ground. A vertical groove 11 is formed inside the support column 2. A slot 12 is provided at the bottom of the vertical groove 11. A slider 13 is provided at the upper part of the vertical groove 11. The slider 13 is slidably installed in the vertical groove 11. An insertion rod 14 is provided at the lower side of the slider 13. A spring 15 is provided between the upper side of the slider 13 and the top of the vertical groove 11. One installation rod 16 is provided at each end of the guardrail frame 3. A groove 17 matching the insertion rod 14 is provided at the upper end of the installation rod 16. A short rod 18 matching the slot 12 is provided at the lower end of the installation rod 16.

[0016] The guardrail frame 3 is composed of a cross bar 6, a vertical bar 7 and a partition bar 8. The cross bar 6 and the vertical bar 7 are connected end to end to form a rectangular frame. A plurality of partition bars 8 are arranged between the vertical bars 7. The partition bars 8 are perpendicular to the vertical bars 7. A warning board 9 is provided in the middle of the partition bar 8. Reflective layers are coated on both sides of the warning board 9 to improve visibility at night or under low light conditions.

[0017] The support base 1 is a U-shaped base. Support feet 10 are provided at both ends thereof. The through holes 4 pass through the support feet 10, which increases stability and adaptability and can adapt to different ground conditions.

[0018] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
