Description

Technical Field

[0001] This utility model relates to the field of highway traffic facilities technology, specifically a highway reconstruction and expansion directional sign. Background Technology

[0002] During highway reconstruction and expansion, directional signs are crucial for ensuring vehicle safety and smooth traffic flow. However, existing directional signs have many shortcomings. At night or in adverse weather conditions such as heavy rain or fog, the reflective materials of traditional directional signs have insufficient reflectivity, making them difficult for drivers to clearly see and increasing the risk of traffic accidents. Furthermore, most existing directional signs are installed at a fixed angle, making it impossible to adjust them according to different road conditions and lighting directions.

[0003] Therefore, how to solve the above-mentioned technical problems has become the subject of this utility model. Utility Model Content

[0010] The upper connecting seat and the lower connecting seat are both fixedly connected to one end of one of the cross-shaped universal joints on the side facing the rectangular frame. The other end of the cross-shaped universal joint is fixedly connected to a second connecting plate. The second connecting plate and the first connecting plate corresponding to its position are fixedly connected by fixing bolts. The side of the cross-shaped universal joint near the panel is connected to the multi-angle adjustment mechanism.

[0011] The multi-angle adjustment mechanism includes a rotating seat fixedly connected to the outer wall of the cross-shaped universal joint, and two rotating seats located on the same side in the vertical direction are arranged facing each other;

[0012] The outer side of the mounting column is coaxially fitted with a sliding sleeve that is vertically slidably connected to it. Two support seats are respectively provided on the upper and lower sides of the sliding sleeve. The two support seats are rotatably connected to one end of two support rods, and the other end of the two support rods are rotatably connected to rotating seats located on the upper and lower sides respectively.

[0013] The sliding sleeve is connected to a vertical adjustment component and a horizontal adjustment component respectively.

[0014] The vertical adjustment component includes a rectangular threaded sleeve that is rotatably connected to the four corners of the top of the lower connecting seat and is vertically upward. Each threaded sleeve has a threaded rod threadedly connected to its inner side. The top end of the threaded rod is fixedly connected to the bottom of the sliding sleeve. An auxiliary rotating seat is sleeved on the outside of the mounting column, which rotatably engages with the four threaded sleeves respectively.

A lower support frame is fixedly connected between the lower connecting seat and the mounting post. The lower support frame is vertically rotatably connected with a first rotating rod. The outer side of the first rotating rod is coaxially fitted with a third gear that meshes with the second gear. The outer sides of both first rotating rods are coaxially fitted with a first transmission disc. A first transmission belt is fitted between the two first transmission discs. One of the first rotating rods is coaxially fixedly connected to the output end of the first motor.

[0016] The horizontal adjustment component includes a gear disk coaxially sleeved on the outer side of the sliding sleeve and rotatably connected thereto. The sliding sleeve is respectively disposed on the upper and lower sides of the gear disk. An upper support frame is fixedly connected between the mounting column and the sliding sleeve.

During use, the angle of the sign can be adjusted according to the lighting and the progress of road reconstruction and expansion. When adjusting vertically, the first motor is started, which drives the second gear to rotate through the third gear. The second gear drives the first gear to rotate, thereby driving the threaded sleeve to rotate, allowing the threaded rod to move up and down. The threaded rod drives the sliding sleeve to move up and down.
