Riveting type semitrailer frame

The invention relates to the technical field of automobile accessories, in particular to a riveting type semitrailer frame which comprises a cold bending longitudinal beam rod, a front cross beam structure, a first 100mmW scale structure, a second 100mmW scale structure, a third 120mmW scale structure, traction base structures, a side beam structure and third diagonal draw bars. Two bent longitudinal beam rods are symmetrically arranged on the edge beam structure, the traction base structures used for traction are fixed to the bent longitudinal beam rods, the traction base structures are connected to front cross beam structures used for reinforcement and arranged on the bent longitudinal beam rods, and the front cross beam structures are fixed to the edge beam structure. The third diagonal draw bars used for reinforcement are arranged between the edge beam structures and the bent longitudinal beam rods, triangles are formed among the edge beam structures, the bent longitudinal beam rods and the third diagonal
