The utility model relates to the technical field of sign post structures, in particular to a ground
cantilever type sign post structure which comprises a foundation pit, a supporting embedded part is embedded in the foundation pit, a supporting
flange plate is arranged at the top of the supporting embedded part, and a sign vertical rod is arranged at the top of the supporting
flange plate; a
cantilever rod is arranged above the sign vertical rod, a connecting
flange plate is arranged between one end, close to the sign rod, of the
cantilever rod and the sign vertical rod, a sign board is fixedly arranged on the cantilever rod, a mounting
assembly is arranged on the cantilever rod, a connecting
assembly is arranged on the sign board, and the mounting
assembly and the connecting assembly can be quickly and fixedly connected. According to the signboard, the cantilever rod and the signboard body are rapidly and fixedly connected through the mounting assembly and the connecting assembly, and compared with a traditional mode that the signboard body and the cantilever rod are connected through bolts, the signboard is faster, so that the working efficiency of signboard mounting is improved, and the working time at high altitude is shortened; therefore, the
potential risk in the installation and maintenance process is reduced.
