Description

Technical Field

[0001] The utility model relates to the technical field of warning devices for urban road construction, in particular to a warning device for urban road construction. Background Art

[0002] The primary purpose of urban road construction warnings is to ensure safety and maintain order. On the one hand, prominent warning signs serve to alert pedestrians and vehicles to construction areas, preventing accidents such as collisions and falls and ensuring their personal safety. On the other hand, they inform people of road construction activities, guide vehicles to plan their routes appropriately, avoid traffic congestion, and ensure smooth traffic flow within and around construction sites. Furthermore, these warnings help protect the safety of construction workers, allowing them to carry out road construction work in a relatively safe and orderly environment.

[0003] Current warning devices used in urban road construction are mostly single warning signs, which have numerous shortcomings: First, they are limited in functionality, typically providing only a single warning message. Second, complex construction warning environments require different warning messages for different scenarios, and traditional methods require multiple warning signs, making them inconvenient and inefficient. Given these issues, improvements and optimizations are necessary for existing urban road construction warning devices. Utility Model Content

[0027] A gap is provided on the left side of the outer frame 2 , and the warning cloth 36 enters into the outer frame 2 through the gap.

[0028] There are two supporting legs 1 , which are distributed on both sides of the bottom of the outer frame 2 .

[0029] The winding mechanism 3 includes a limit frame 35, which is fixedly connected to the outer frame 2. A stretching bar 37 is slidably connected to the right side of the limit frame 35. The top and bottom of the stretching bar 37 are fixedly connected to a limit rod 38. A warning cloth 36 is fixedly connected to the left side of the stretching bar 37. A rotating drum 34 is fixedly connected to the left side of the warning cloth 36. The rotating drum 34 is rotatably connected to the outer wall of the fixed rod 32. The top and bottom of the fixed rod 32 are fixedly connected to the winding drum 31. The top and bottom of the winding drum 31 are respectively fixedly connected to one end of a coil spring 33, and the other end of the coil spring 33 is fixedly connected to the outer wall of the rotating drum 34. The right side of the winding drum 31 is fixedly connected to the left side of the outer frame 2.

[0030] By setting up a winding mechanism 3 and multiple winding drums 31, when in use, different warning words are set in the warning cloth 36 of different winding drums 31 according to different usage scenarios. When it is needed, the warning cloth 36 is stretched out from the warning cloth 36 wound on the rotating drum 34 in cooperation with the coil spring 33 through the limiting rod 38 in cooperation with the stretching bar 37. When the limiting rod 38 and the elastic limiting buckle 42 are engaged, the warning cloth 36 is completely laid flat in the outer frame 2, thereby achieving the purpose of using different warning words in different scenarios.

[0031] Slide grooves 5 are provided at the top and bottom of the outer frame 2 corresponding to the limit rods 38 , and the limit rods 38 are slidably connected to the right side of the slide grooves 5 .

When it is necessary to contact the engaged state, it is only necessary to toggle the toggle block 43. Under the force of the winding spring 33, the limit rod 38 and the elastic limit buckle 42 are disengaged, thereby wrapping the warning cloth 36 onto the rotating cylinder 34.
