Description

Technical Field

[0001] This utility model relates to the field of road sign facilities technology, and in particular to a highway attached traffic sign fixing device. Background Technology

[0002] Highway enforcement officers frequently encounter situations involving the installation of traffic signs. Traffic signs are commonly temporarily fixed to the road surface using methods such as tripods, which pose significant safety hazards. This necessitates timely installation and removal of traffic signs. In windy weather, sandbags and stones are often used for reinforcement, further complicating timely removal.

[0003] Related patents disclose technical solutions for fixing signs to guardrails, namely, an attached sign fixing method, which reduces safety hazards and the urgency of deployment and removal. For example, patent publication number CN221972156U discloses a road traffic sign, including a pole, a display board disposed at the upper end of the pole, and a fixing component located at the lower end of the pole for connecting with a road guardrail; the fixing component includes a crossbar connected to the pole and a clip fixedly connected to the crossbar, the clip having a slot for inserting the road guardrail; the pole includes a main pole for connecting the display board and a secondary pole for facilitating connection with the road guardrail, both the main pole and the secondary pole are connected to the fixing component, and the upper end of the secondary pole slides into the lower end of the main pole. When a temporary sign is needed, first clamp the secondary pole to the road guardrail, then slip the main pole onto the secondary pole, and then clamp the main pole to the road guardrail, connecting the sign to the guardrail. The main pole has a clamping screw, which is threaded onto the main pole, with the end of the clamping screw acting on the secondary pole. When the upper end of the secondary pole is inserted into the lower end of the main pole, tighten the clamping screw, pressing it onto the secondary pole and fixing the secondary pole relative to the main pole.

[0004] The back of the display panel is connected to several sleeves by rivets. The upper end of the main rod is inserted into one of these sleeves, and a locking bolt passes through the main rod. The locking bolt is located below the display panel, and the lower side of the display panel abuts against the locking bolt. The height of the display panel is adjusted by tightening the locking bolt. If the display panel is too high, adjusting its height requires either climbing up using a ladder or removing the main rod, which is inconvenient. Summary of the Invention

[0026] For example, the guardrail 60 includes an upper flange 61, a lower flange 61, and a protrusion 62. The cross-section of the guardrail 60 is wavy. The upper surface of the upper flange 61 is the top surface of the guardrail 60, and the lower surface of the lower flange 61 is the bottom surface of the guardrail 60. The protrusion 62 is located between the upper flange 61 and the lower flange 61. There are upper protrusion 62, middle protrusion 62, and lower protrusion 62 between the upper flange 61 and the lower flange 61. The upper protrusion 62 and the lower protrusion 62 are located on one side of the guardrail 60, and the middle protrusion 62 is located on the other side of the guardrail 60.

[0027] When installing the highway attached traffic sign fixing device, the upper clamp 10 abuts against the upper flange 61, the lower clamp 10 is on the ground, the lower upright 20 slides relative to the upper upright 20, the upper clamp 10 and the lower clamp 10 move closer to each other, the lower clamp 10 abuts against the lower flange 61, the guardrail 60 is clamped between the upper clamp 10 and the lower clamp 10, the height of the post 30 relative to the guardrail 60 is adjusted, and the upper locking part 50 and the lower locking part 50 are used to fix the post 30 to the upper upright 20 and the lower upright 20 respectively. The upper locking part 50 and the lower locking part 50 also fix the upper upright 20 and the lower upright 20 to each other at the same time.
