Description

Technical Field

[0001] This utility model relates to the field of road control and instruction technology, specifically a traffic control and instruction sign for road tunnel entrances and exits. Background Technology

[0002] Several problems exist with existing traffic control signs at road tunnel entrances and exits that urgently need to be addressed. Firstly, the installation height and angle of these signs are mostly fixed, making it impossible to flexibly adjust them according to actual traffic flow, vehicle type, and weather conditions. This results in situations where drivers cannot clearly see the information on the signs, such as when vehicles are queuing and obstructing visibility, or when inclement weather affects visibility, potentially leading to traffic congestion or even accidents. Secondly, existing signs lack adequate protective measures, and their internal adjustment mechanisms are susceptible to damage from external environmental factors (such as rain, dust, and impacts), reducing their lifespan and maintenance cycle, and increasing management costs. Therefore, a new type of traffic control sign for road tunnel entrances and exits that can flexibly adjust its height and angle while possessing good protective performance is needed to improve the efficiency and safety of traffic control and reduce traffic accidents. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a traffic control sign for road tunnel entrances and exits.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a traffic control sign for a road tunnel entrance / exit, comprising an adjustment assembly, the adjustment assembly comprising a fixed base shell, a first rotating shaft connected to one side of the fixed base shell, a rotating knob provided at one end of the first rotating shaft, a bolt provided on the rotating knob, a first bevel gear connected to the end of the first rotating shaft away from the rotating knob, a second bevel gear provided on one side of the first bevel gear, a second rotating shaft connected to the middle position of the second bevel gear, a first threaded rod connected to the upper end of the second rotating shaft, a threaded sleeve provided on the outer side of the first threaded rod, and a connecting limiting sleeve provided on the outer side of the threaded sleeve.

[0005] As a further description of the above technical solution:

[0006] An angle adjustment unit is provided on the upper side of the adjustment component. The angle adjustment unit includes a base plate disposed on a threaded sleeve. A second threaded rod is disposed on the upper side of the base plate. A nut is connected to the outer side of the second threaded rod. A rotating ring is disposed on the upper side of the base plate. An indicator body is connected to the upper side of the rotating ring.

[0007] As a further description of the above technical solution:

[0008] A protective cover is hinged to one side of the fixed base shell. The rotating knob and bolt are located on the inner side of the protective cover and on the outer side of the fixed base shell. The bolt is threaded onto the fixed base shell.

[0009] As a further description of the above technical solution:

[0010] The first rotating shaft is rotatably connected to the fixed base shell, the first bevel gear is fixedly disposed at one end of the first rotating shaft, and the first bevel gear is meshed with one side of the second bevel gear.

[0011] As a further description of the above technical solution:

[0012] The second rotating shaft is rotatably connected to the inner side of the fixed base shell, and the second rotating shaft is fixedly connected through the middle position of the second bevel gear. The threaded sleeve is threadedly connected to the outer side of the first threaded rod, and the threaded sleeve is slidably connected to the inner side of the connecting limiting cylinder.
