When the traffic volume reaches a certain level, the vehicles driving in the inner lane will not be able to see the information on the roadside signs due to the obstruction of the large vehicles on the outer side. In order to enable various vehicles driving on the highway to see the sign information in time, especially when there is a lot of information on the sign and other forms of signs are not competent, it is absolutely necessary to set up a gantry structure sign. The existing gantry is generally equipped with two upper and lower parallel beams. Generally, the distance between the two beams is fixed and cannot be adjusted according to the size of the sign, so the installation stability of the sign cannot be guaranteed.

[0030] Second embodiment

[0031] See also Figure 4 and Figure 5 ,in Figure 4 is a schematic diagram of the overall structure of the second embodiment, Figure 5 It is a cross-sectional view of the internal structure of the lifting assembly of the second embodiment.

[0032] On the basis of the first embodiment, a traffic sign gantry of the utility model further includes two sets of lifting components, and the lifting components include a servo motor 201 , a threaded rod 202 , a threaded sleeve 203 , a connecting block 204 and a baffle 205 .

[0033] Each of the brackets 101 has two movable cavities 206, and each group is respectively arranged in the corresponding movable cavity 206 and is connected to the fixed plate 103. By arranging the lifting component on the bracket 101, the height of the fixed plate 103 can be adjusted by using the lifting component, which facilitates the installation or removal of the billboard 102. In addition, the passing height of the vehicle is limited by adjusting the height of the fixed plate 103, which increases practicality.

[0034] The servo motor 201 is fixedly connected to the bracket 101 and is located in the movable cavity 206. One end of the threaded rod 202 is fixedly connected to the output end of the servo motor 201, and the other end of the threaded rod 202 is rotatably connected to the bracket 101. The threaded sleeve 203 is sleeved on the outside of the threaded rod 202 and threadedly matched with the threaded rod 202. The two ends of the connecting block 204 are respectively fixedly connected to the threaded sleeve 203 and the fixed plate 103 and pass through the movable cavity 206. When the height of the fixed plate 103 needs to be adjusted, the servo motors 201 in the two brackets 101 are started, and each of the The output end of the servo motor 201 controls the threaded rod 202 to rotate in the movable cavity 206. Since the threaded sleeve 203 is threadedly matched with the threaded rod 202, the threaded sleeve 203 will move up or down on the threaded rod 202. At the same time, the threaded sleeve 203 drives the fixed plate 103 to move through the connecting block 204, so that the height of the fixed plate 103 can be adjusted. The billboard 102 can be easily installed or disassembled by adjusting the height of the fixed plate 103. In addition, the height of the fixed plate 103 can be adjusted to limit the passing height of the vehicle. In this way, the practicality of the gantry can be increased.

[0036] When the height of the fixed plate 103 needs to be adjusted, the servo motors 201 in the two brackets 101 are started, and the output end of each servo motor 201 controls the threaded rod 202 to rotate in the movable cavity 206. Since the threaded sleeve 203 is threadedly matched with the threaded rod 202, the threaded sleeve 203 moves up or down on the threaded rod 202. At the same time, the threaded sleeve 203 drives the fixed plate 103 to move through the connecting block 204, so that the height of the fixed plate 103 is adjusted. The billboard 102 can be installed or disassembled by adjusting the height of the fixed plate 103. In addition, the height of the vehicle can be limited by adjusting the height of the fixed plate 103. In the above manner, the practicability of the gantry can be increased. The baffle 205 is arranged in the movable cavity 206, and the baffle 205 protects the servo motor 201 and prevents it from being exposed.
