Detailed Description

The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

One embodiment of the present invention is provided below:

referring to fig. 1 to 5, a packing box with an adjustable inner liner comprises a box body 1 made of hard paperboard, a box cover 2, a side plate 11 and a bottom plate 12, and further comprises an inner lining plate 3 (preferably made of hard paperboard) arranged in the box body 1, wherein the inner lining plate 3 and the side plate 11 are arranged in parallel, opposite and at intervals, a first elastic sheet 5 (preferably made of plastic) arched and gathered towards the center of the box body 1 is arranged on the inner lining plate 3, and the first elastic sheet 5 is detachably connected with the inner lining plate 3, so that the arched height of the first elastic sheet 5 is adjustable.

It should be noted that the first elastic sheet 5 is detachably connected with the inner lining plate 3, which means that the first elastic sheet 5 can be detached from the inner lining plate 3 for moving and adjusting, and then connected to the inner lining plate 3 after being adjusted in place. The arching height of the first elastic sheet 5 can be adjusted by adjusting the distance between the two sides of the first elastic sheet 5. Specifically, the wider the distance between the two sides of the first elastic sheet 5, the gentler the radian of the first elastic sheet 5, the lower the arching height, the narrower the distance between the two sides of the first elastic sheet 5, the larger the radian of the first elastic sheet 5, and the higher the arching height. The gift in the middle can be propped against by the matching of the first elastic sheets 5.

Further, in this embodiment, the first elastic piece 5 includes a main body portion 51, a fastening portion 52, and a connecting portion 53 for connecting the main body portion 51 and the fastening portion 52, a strip-shaped hole 31 is formed in the inner lining 3 corresponding to a corner position of the main body portion 51, a plurality of limiting grooves 32 are formed on the outer side surface of the inner lining 3 at intervals along the strip-shaped hole 31 (the limiting grooves 32 do not penetrate through the inner lining 3), the fastening portion 52 is used for matching with the limiting grooves 32 to connect the first elastic piece 5 to the inner lining 3, and the connecting portion 53 penetrates through the strip-shaped hole 31 and can slide in the strip-shaped hole 31.

When the first elastic sheet 5 is connected to the inner lining plate 3, the buckling part 52 is embedded into the limiting groove 32 to fix the relative position between the first elastic sheet 5 and the inner lining plate 3, when the arching height of the first elastic sheet 5 needs to be adjusted, the main body part 51 is pinched by a hand to be pushed from inside to outside, so that the buckling part 52 is separated from the limiting groove 32, at the moment, the connecting part 53 can move in the range of the strip-shaped hole 31, and after the first elastic sheet is moved to the place, the main body part 51 is pulled from outside to inside, so that the buckling part 52 is embedded into the limiting groove 32 at the corresponding position again.

In other embodiments, the first elastic sheet 5 and the inner lining plate 3 can be detachably connected in other manners, so that the arching height of the first elastic sheet 5 can be adjusted. For example, a plurality of positioning holes are arranged at the inner lining plate 3 at intervals in the transverse direction, and the first elastic sheet 5 is detachably connected with the inner lining plate 3 by matching the positioning pins arranged at the corners of the first elastic sheet 5 with the positioning holes.

Further, the novel corrugated board structure further comprises a reinforcing plate 6, wherein the reinforcing plate 6 is fixedly arranged between the inner lining plate 3 and the side plate 11, and the reinforcing plate 6 is formed by splicing a plurality of crossed hard paper strips. Note that the area where the reinforcing plate 6 is provided should avoid the range of the strip-shaped hole 31 so as not to hinder the adjustment of the first elastic piece 5.

Further, the inner lining plate comprises a plurality of second elastic sheets 7 (preferably plastic sheets) positioned on the inner side of the inner lining plate 3, the second elastic sheets 7 are fixedly arranged on the bottom plate 12 and are arched upwards, and the second elastic sheets 7 are provided with supporting plates 4 (preferably hard paper plates). The second elastic sheet 7 is used for improving the buffering and damping performance of the bottom of the box body 1, and can be nailed on the bottom plate 12 along the edge of the second elastic sheet 7 by staples or fixed in an adhesive mode.

Further, referring to fig. 2, the limiting groove 32 is disposed to be inclined opposite to the curvature direction of the adjacent main body 51. The limiting groove 32 is formed in this way, so that the buckling portion 52 of the first elastic sheet 5 and the adjacent main body portion 51 are in a reverse bending shape, and the first elastic sheet 5 is not easy to loosen from the inner lining plate 3 in a normal use process.

Further, the outer surface of the reinforcing plate 6 is bonded and fixed to the inner surface of the side plate 11, and the inner surface of the reinforcing plate 6 is bonded and fixed to the outer surface of the lining plate 3.

Compared with the prior art, the utility model has the technical effects that:

the present invention clamps and fixes the present in the box body 1 through the first elastic sheets 5, can better position and buffer the presents with different shapes and sizes by adjusting the arching height of each first elastic sheet 5, has better universality, has higher strength and is not easy to deform when being stressed or impacted due to the composite structure formed by the side plates 11, the reinforcing plates 6 and the lining plate 3, and can improve the damping and buffering performance of the bottom of the box body 1 through the arrangement of the second elastic sheets 7.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may be modified or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
