Platform trailer with supporting leg structure

Abstract

The utility model discloses a platform trailer with a supporting leg structure, which comprises a trailer body, a jacking piece and a supporting leg piece, the supporting leg piece and the jacking piece are both rotatably connected to the bottom of the trailer body and can both rotate to a vertical state or a folded state, the jacking piece is rotatably connected with a gasket piece, and the gasket piece is rotatably connected with the supporting leg piece. When the jacking part rotating to the vertical state abuts against the ground and jacks the trailer body to the preset height, the supporting foot parts can rotate to the vertical state so as to abut against the ground to support the trailer body. By means of the structure, due to the supporting effect of the supporting foot pieces, the acting force borne by the jacking piece by the trailer body is greatly reduced or eliminated, and therefore the probability that the jacking piece breaks down and is damaged under the condition that the platform trailer is lifted for a long time can be reduced.
