The invention discloses an anti-bumping device used in the transportation process. The anti-bumping device comprises an anti-bumping box. Grooves are formed in the bottom of the anti-bumping box. Thebottoms of the grooves are fixedly connected with the bottoms of damping springs. Rotation shafts are arranged on the bottom side edge of the anti-bumping box and movably connected with side baffles.Clamping grooves are evenly formed in the inner surfaces of the side baffles and are fixedly connected with the end portions of sliding plates. The inner surfaces of the side baffles and the inner surfaces of fixing baffles are provided with elastic layers. The upper portions of the side baffles and the upper portions of the fixing baffles are fixedly connected with a cover plate. According to theanti-bumping device used in the transportation process, goods can be fixed by adjusting the distance between the sliding plates; meanwhile, a fixing structure is formed by the sliding plates and theside baffles; an elastic cotton plate and the elastic layers play a buffering and protection role; and the problems that ordinary foam and the like are adopted in common anti-bumping devices at present for protection, the effect is poor, meanwhile, the foam shape is fixed, goods different in shape cannot be fixed, bumping reduction cannot be achieved, and flexibility is poor are solved.
