Cantilever wheel mechanism applied to storage cabinet spreading vehicle

The utility model discloses a cantilever wheel mechanism applied to a storage cabinet spreading vehicle, which can solve the problem that when the existing storage cabinet spreading vehicle runs, a wheel axle and wheels rotate together, and the axle is stressed by the weight of the vehicle body to form alternating stress, so that the stressed part of the axle is easy to fatigue and damage. Compared with an existing spreading vehicle through shaft, the weight and the size of each part are reduced after the mechanism is disassembled, the operability of installation and maintenance is improved, and the machining difficulty and the equipment manufacturing cost are reduced. The wheel comprises a cantilever shaft, a wheel body, an end cover and a supporting beam body, the supporting beam body isfixedly arranged at the lower end of the vehicle body frame in use; the two cantilever shafts are symmetrically installed at the two ends of the supporting beam body. The wheel body is installed at the end of the cantilever
