Description

Upper cover splicing type strip rotational molding packaging box

Technical Field

The utility model relates to a packing box field specifically is a rectangular rotational moulding packing box of upper cover concatenation formula.

Background

Traditional rotational moulding packing box, box case lid are integrative rotational moulding, and this is to small-size case, and length dimension is less than waiting 3 meters's case, and the strict control of production technology can satisfy basically. However, in the case with the size of 3 meters or more, due to the artificial rotational molding production process and the large influence of environmental factors, the matching size of the case body and the case cover is different after the product is formed, and the case cover cannot be covered or cannot be sealed after the case cover is forcedly covered. Or the box cover of the box body is forcibly shaped to be uniform in size in the production process, so that the assembly and matching problems in production are solved. But the forced shaping can leave internal stress in the product, the internal stress is gradually released after a period of time, the product has dimensional deviation, the quality is good when the product is produced and stored, and the problems of sealing and dislocation of the box body and the box cover occur after the product is stored for a period of time.

SUMMERY OF THE UTILITY MODEL

The utility model provides a rectangular rotational moulding packing box of upper cover concatenation formula, simple structure solves box case lid dimensional deviation and leads to the lock not in place, or sealed bad problem, improves the stability of quality.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a rectangular rotational moulding packing box of upper cover concatenation formula, includes the box and is located the case lid of box upper end, the case lid by half case lid on the left side, half case lid on the right side and be located the middle apron concatenation between half case lid on the left side and half case lid on the right side and form.

Preferably, sealing strips are arranged between the middle cover plate and the left half box cover and between the middle cover plate and the right half box cover.

Preferably, the left half case cover and the right half case cover are provided with convex ribs at positions where the sealing strips are installed.

Preferably, the cross section of the sealing strip is round, square, trapezoid, T-shaped or D-shaped.

Preferably, at least one of the left half case cover and the right half case cover is connected with the middle cover plate through a plurality of screws.

Preferably, the left half box cover, the right half box cover and the middle cover plate are connected with the box body through a plurality of fasteners.

Preferably, handles are mounted on the side walls of the left half case cover and the right half case cover.

Compared with the prior art, the beneficial effects of the utility model are that:

the spliced box cover structure is adopted, so that the problems that the upper box cover and the lower box cover are asymmetrical in size, the box cover and the box cover are dislocated in a matched mode due to size deviation and poor in sealing performance caused by the process are effectively solved. The product quality qualification rate is improved, the production cost is reduced, the left half box and the right half box are of a symmetrical structure, the left half box and the right half box are produced by using the same rotational molding die, and the left half box cover and the right half box cover are formed by post-processing and assembling accessories, so that the die development cost and the production cost of the box cover are saved.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1-5, the utility model provides a rectangular rotational moulding packing box of upper cover concatenation formula, include box 1 and the case lid that is located box 1 upper end, the case lid by half left case lid 3, half right case lid 2 and be located the middle apron 4 concatenation between half left case lid 3 and half right case lid 2 and constitute.

The middle cover plate 4 can cover enough clearance between the left half case cover 3 and the right half case cover 2, and size difference of the case cover in the length direction is met.

In order to improve the leakproofness, middle apron 4 and left half case lid 3 and right half case lid 2 between be provided with sealing strip 7, simultaneously, left half case lid 3 and right half case lid 2 on install the position of sealing strip 7 and be provided with protruding muscle 8, protruding muscle 8 pushes down sealing strip 7 and plays fine sealed effect.

The cross section of the sealing strip 7 is round, square, trapezoid, T-shaped or D-shaped, and can be replaced and used as required.

Example (b):

at least one of the left half box cover 3 and the right half box cover 2 is connected with the middle cover plate 4 through a plurality of screws 9.

The left half box cover 3, the right half box cover 2, the middle cover plate 4 and the box body 1 are connected through a plurality of fasteners 6, and the number of the fasteners 6 can be adjusted as required.

The lateral walls of the left half box cover 3 and the right half box cover 2 are provided with handles 5, so that the lifting is convenient.

While the invention has been described above with reference to an embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, as long as there is no structural conflict, the various features of the disclosed embodiments of the present invention can be used in any combination with each other, and the description of such combinations is not exhaustive in the present specification only for the sake of brevity and resource conservation.
