Description

Technical Field

[0001] The present application relates to the technical field of high-pressure oil pump packaging, and in particular to a small-scale integrated full-paper packaging box for a high-pressure oil pump and a folding method thereof. Background Art

[0002] The high-pressure oil pump of a diesel vehicle is made of steel as a whole. It is small in size and heavy in weight. There are many protruding shafts, interfaces, and nuts on the outside. When it is shipped from the manufacturer, attention should be paid to the product's anti-rust, anti-collision, and anti-fall protection. Due to competition among enterprises and the increasing demand for environmental protection, the main packaging form is corrugated cardboard boxes, and anti-rust is divided into two types: meteorological anti-rust plastic bags and anti-rust paper. Considering the way downstream customers use it, it is divided into small packaging (usually 4 packs) and large packaging (usually 48~60 packs). Except for the relatively weak interface position, the product itself is very strong. The usual design is to avoid isolation and fixation behind the interface, and pursue the lowest packaging material cost under the premise of effective protection.

The high-pressure oil pump is easy to directly contact with the box body, which is easy to damage the oil pump during the bumping process, and the high-pressure oil pump cannot be effectively fixed in the box body.

The lower lining top plate 8 is the top plate of the lower lining structure 18. The lower lining third side plate 5 overlaps with the lower lining first side plate 1. The two lower lining half top plates 2 are spliced and then overlap with the lower lining top plate 8. The two lower lining half bottom plates 4 are spliced to form the bottom plate of the lower lining structure 18.

[0025] 3. Fold the upper lining side plate, upper lining half bottom plate 11, and upper lining half top plate 13 upward or downward along the indentation line to the upper side or lower side of the upper lining bottom plate 15.

The top surfaces of the two upper lining top plates and the upper lining bottom plate 15 form the top plate of the upper lining structure 17.

[0027] It should be noted here that the packaging box of this application is a corrugated cardboard box. The positioning notch 7 and the positioning plate 6 of this application can effectively fix the high-pressure oil pump, and the cavity folding structure can separate the high-pressure oil pump from the box body. In addition, since the packaging box is foldable, this application has the technical effects of reducing costs and compressing the packaging space.
