The swing link 50 may be integrally received in the frame 10, and the swing link 50 may be extended outwardly so that the outer end thereof moves forward of the frame 10 together with the auxiliary roller 60.
The swing rod 50 can be retracted into the frame 10 when the cabinet is in butt joint, the swing rod 50 can be adjusted to be in an extended state during normal transportation, and the auxiliary roller 60 is suspended during normal walking because the auxiliary roller 60 is slightly higher than the walking wheel 40, and if forward tilting occurs, the auxiliary roller 60 forms a front support in a landing manner. The auxiliary roller 60 is only slightly higher than the road wheel 40, for example, the auxiliary roller 60 is 1-5 cm above the ground.
Preferably, a groove 11 extending transversely is arranged at the lower part of the front side of the frame 10, and the inner end of the swing rod 50 is movably connected in the groove 11. Further preferably, the groove 11 has an upper top surface and a lower bottom surface, and the lower bottom surface of the groove 11 is provided with a yielding notch corresponding to the auxiliary roller 60. Thus, the upper side and the lower side of the groove 11 enclose the swing rod 50, and the stability is better.
Preferably, the inner end of the swing link 50 is pivotally connected to the frame 10, so that the folding is more convenient.
Preferably, the number of the swing rods 50 is two, and the swing rods are symmetrically arranged left and right. Therefore, the auxiliary rollers 60 are arranged on the two swing rods 50, the supporting points are more, the stress is more uniform during dumping, and the safety performance is better.
