Truck tailstock buffer crash-proof rack

The device is a novel rear buffer anti-collision frame of the truck; the buffer part includes a primary buffer component bumper, a rubber mat and a secondary buffer component damp buffer oil cylinder. The most important part in the whole anti-collision frame is the damp buffer oil cylinder in the outside; the damp buffer oil cylinder is filled with the viscous liquid, and is provided with a damp hole, a sealing pin, an elastic pressing piece and an oil injection hole. When the impact affects the anti-collision frame, the bumper and the rubber mat absorb part of the energy through the elastic deformation; then the piston presses the liquid inward to transfer the energy of the impact to the liquid. Finally, the liquid presses the sealing pin of the damp hole on the surface of the oil cylinder to be open; the liquid is sprayed into the air through the damp hole to release the energy. Thus, the impact transmitted to the truck is greatly buffered and lowered.
