Further, the outer waterproof layer adopts a plastic waterproof film or a waterproof paint coating.

Further, the inner waterproof layer is made of a plastic waterproof film.

Furthermore, the supporting bars are arranged at equal intervals, and the cross sections of the supporting bars are rectangular.

Further, the load uniform distribution pieces and the supporting bars are arranged in a staggered mode.

Furthermore, the load distribution piece adopts a strip-shaped structure with a semicircular cross section, and the plane side of the load distribution piece props against the inner supporting layer.

Furthermore, the load uniform distribution piece adopts a hemispherical structure, and the plane side of the load uniform distribution piece props against the inner supporting layer.

Further, the base plate adopts a rubber plate.

The invention has the advantages and positive effects that:

the invention has reasonable structural design, strong buffering capacity, stable and reliable structure and difficult damage in the using process. When receiving the impact, the honeycomb cardboard layer bears the first load, can effectively bear, effectively cushions the impact force, when the impact force is great, then can further transmit outer supporting layer department with the load, and then on the bigger area of the boxboard that will receive the furthest's distribution of load, avoid local too big and damage of bearing. Meanwhile, the inner surface and the outer surface of the box board are both provided with waterproof layers, so that the moisture-proof and waterproof effects are good.

Detailed Description

It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings, which are merely for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be construed as limiting the invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention, the meaning of "a plurality" is two or more unless otherwise specified.

In the description of the invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be construed broadly, e.g. as being fixed or detachable or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The following detailed description of the embodiments of the invention is provided.

An impact-resistant box board for a packing box is shown in figures 1 and 2 and comprises a panel layer 1, an insulating layer 2, a honeycomb paperboard layer 3, an outer supporting layer 4 and an inner supporting layer 5 which are sequentially arranged, wherein a bearing structure is arranged between the outer supporting layer and the inner supporting layer; the bearing structure comprises a base plate 6, a plurality of supporting bars 7 between the base plate and an outer supporting layer, and a plurality of load uniform distribution pieces 8 between the base plate and an inner supporting layer; an outer waterproof layer 9 is arranged on the outer side of the panel layer; an inner waterproof layer 10 is arranged on the inner side of the inner supporting layer. The packing box made of the box board provided by the invention can achieve stronger shock resistance without excessive additional reinforcing structures, has good use performance and easy assembly, and is also beneficial to recycling of the whole block.

Generally, the outer waterproof layer is a plastic waterproof film or a waterproof paint coating. The inner waterproof layer is a plastic waterproof film. The packing box that this boxboard was made, waterproof, dampproofing effectual, simultaneously, owing to set up the heat preservation, consequently, the heat preservation effect is also better.

When the structure is arranged, the supporting bars are arranged at equal intervals, and the cross sections of the supporting bars are rectangular. The load uniform distribution pieces and the supporting bars are arranged in a staggered mode, namely the load uniform distribution pieces are not arranged over against the supporting bars, but arranged on the other side of the base plate in a staggered mode with the supporting bars on the other side, so that the overall buffering performance of the bearing structure is improved, and the base plate is allowed to have a certain deformation amount.

In an alternative embodiment, the load distribution member is in the form of a strip of semicircular cross-section, the planar side of which abuts the inner support layer.

In another alternative embodiment, the load distribution member is of a hemispherical structure, the plane side of the load distribution member abuts against the inner supporting layer, and the spherical side of the load distribution member abuts against the substrate.

The base plate is a rubber plate. Certainly, the base plate can also be made of other flexible materials, the rigidity of the base plate is different from that of the inner supporting layer and the outer supporting layer, the base plate is smaller than that of the inner supporting layer and the outer supporting layer, and the base plate plays a role of fixing supporting bars and load uniform distribution pieces.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
