[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0033] Referring to the drawings Figures 1-4 A spring pad made of paperboard comprises a base plate, the base plate is made of corrugated paperboard, the base plate is divided into a main plate 1 and a fold structure 2 symmetrically arranged at both ends of the main plate 1, the number of the fold structure 2 at each end of the main plate 1 is two, and the two fold structures 2 at the same end are arranged at intervals.

[0034] Referring to the drawings Figure 4 The length direction of the base plate extends along the main plate 1 to the two end fold structures 2, and the direction perpendicular to the length direction of the base plate is the width direction of the base plate under the same horizontal plane.

[0035] Each fold structure 2 comprises three mutually spaced pre-folds 3, and the pre-folds 3 are parallel to the width direction of the base plate; when folding, two outer pre-folds 3 in each fold structure 2 are sequentially folded at 90 degrees to form side corrugations, and it can be understood that the two outer pre-folds 3 in each fold structure 2 are folded at 90 degrees towards the main plate 1.

[0036] Referring to the drawings Figure 1 The fold structure 2 at the same end forms a support structure after the above folding, the support structure is in the shape of a mouth-shaped structure, and the two fold structures 2 form support side walls of the mouth-shaped structure, that is, the two outer pre-folds 3 in the same fold structure 2 form the upper and lower side corrugations of the mouth-shaped structure, and the two mouth-shaped support side walls are connected to each other through the cooperation of the buckles 5 and the card slots 6, one of the support structures is provided with a buckle 5 near the top side corrugation of the middle part of the main plate 1, and the other support structure is provided with a card slot 6 matched with the buckle 5 near the top side corrugation of the middle part of the main plate 1; the pre-fold 3 in the middle part of each fold structure 2 is bent towards the center of the mouth-shaped structure and is in a concave shape.

[0037] When an object is placed on the spring pad after folding, the pre-fold 3 in the middle part of the fold structure 2 is folded inward to form a buffer structure when the object is jolted during transportation, thereby reducing the impact of the impact force on the object on the spring pad.

[0038] Embodiment 1
