Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a guardrail with a striking reminder function. Background Art

[0002] Guardrails are common equipment on traffic roads, serving as a guide and warning for pedestrians. At night, due to low light conditions, fluorescent yellow-green reflective guide arrows are installed on the guardrails to enhance the warning effect. These arrows absorb sunlight during the day and continue to glow at night, providing a clear warning for pedestrians. However, traditional guardrails still have the following shortcomings when used:

[0003] 1. Guardrails are usually fixed and assembled with bolts, which makes installation and disassembly inconvenient. Moreover, the angle of the guardrail is fixed after assembly and difficult to adjust.

[0004] Therefore, we propose a guardrail with a striking reminder function. Utility Model Content

The fluorescent yellow-green reflective guide arrows are distributed in a triangular shape. Two connecting blocks are fixed to the outer walls of both sides of the guardrail. Positioning columns are fixed to the bottoms of the connecting blocks. Multiple grooves are opened on the outer walls of the positioning columns. The positioning columns and positioning grooves cooperate with each other, and the protrusions and grooves cooperate with each other. The bottom ends of the positioning columns are fixed with thin rods, and the bottom ends of the thin rods are fixed with thick rods.

[0010] The limiting mechanism is arranged on the inner side of the vertical tube and is used to limit the thick rod.

[0011] In a possible design, the limiting mechanism includes a lifting plate, a screw and four limiting blocks. The lifting plate is slidably connected to the inner wall of the vertical tube. Two inclined surfaces are provided on both sides of the lifting plate. The screw rotates and passes through the top of the vertical tube. The bottom end of the screw extends into the vertical tube and is threadedly connected to the lifting plate. The limiting block slides through the outer wall of the vertical tube. The limiting block cooperates with the inclined surface, and the limiting block cooperates with the thick rod.

[0012] In a possible design, two tension springs are fixed between adjacent limit blocks, and the tension springs are located on both sides of the lifting plate.

[0013] In a possible design, a rectangular groove is provided on one side of the limit block, a roller is rotatably connected in the rectangular groove, and the roller cooperates with the inclined surface.

[0014] In a possible design, a clearance groove is provided on one side of the limit block, and the thin rod is located in the clearance groove.

[0015] In a possible design, an adjusting block is fixedly provided at the top end of the screw rod, and a plurality of anti-slip grooves are provided on the outer wall of the adjusting block.

[0016] In a possible design, a plurality of mounting holes are provided on the surface of the base.

[0017] In this application, during assembly, grasp the guardrail so that the thick rod and the thin rod pass through the positioning slot, adjust the position of the guardrail so that the positioning slot and the positioning column are connected, so that a suitable angle is formed between the guardrail and the vertical pipe, and then turn the adjustment block. The adjustment block drives the screw to rotate, and then drives the lifting plate to move. The lifting plate drives the inclined surface to move. The inclined surface contacts and pushes the roller and the limit block to move. The limit block approaches the thin rod until the thin rod enters the clearance slot. The subsequent guardrail assembly is the same.
