Description

Technical Field

[0001] This utility model relates to the field of corrugated packaging box technology, specifically to a cushioning and pressure-resistant packaging box. Background Technology

[0002] Corrugated boxes are one of the most common packaging containers in daily life. They have excellent cushioning and compression resistance properties and are widely and importantly used in various fields, mainly logistics transportation and warehousing.

[0003] Existing technologies have made many improvements to corrugated packaging boxes. For example, Chinese patent CN216784142U discloses a heavy-duty corrugated packaging box. This heavy-duty corrugated packaging box includes a box body, which consists of a left side panel, a right side panel, a front panel, a back panel, a left inner cover and a left inner bottom extending vertically along the left side panel, a right inner cover and a right inner bottom extending vertically along the right side panel, a front outer cover and a front outer bottom extending vertically along the front panel, a rear outer cover and a rear outer bottom extending vertically along the back panel, and a tongue set along one side of the left side panel and bonded to the front panel. The box body is provided with a corner protection frame, which includes four corner protection plates in the height direction of the box body, two corner protection plates in the length direction of the box bottom, and two corner protection plates in the width direction of the box bottom. The corner protection plates in the height direction, the length direction, and the width direction are of a split structure.

[0004] This utility model improves the load-bearing capacity of the packaging box to a certain extent, but it still has the following shortcomings in practical applications: the packaging box structure is relatively complex, the assembly process is relatively cumbersome, and the production efficiency is low.

[0005] Based on this, the present invention designs a cushioned and pressure-resistant packaging box to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a cushioned and pressure-resistant packaging box.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A cushioning and pressure-resistant packaging box includes an outer box and an inner box. The outer box is fitted over the outer side of the inner box and is slidably connected to the inner box. The inner box includes an inner box bottom plate, side cardboard, and end cardboard. The side cardboard, which is symmetrical about the left and right sides of the inner box bottom plate, is fixedly connected to the left and right ends of the inner box bottom plate. The end cardboard, which is symmetrical about the front and back of the inner box bottom plate, is fixedly connected to the front and back ends of the inner box bottom plate. The side cardboard provides support when folded in half, and the end cardboard provides support and sealing when folded in half. The side cardboard includes a side panel, a side top panel, and a side insert panel. The side panel, side top panel, side insert panel, and inner box bottom panel are fixedly connected from the outside to the inside, and there are creases between adjacent cardboard panels.

[0008] Furthermore, multiple sets of side inserts are fixedly connected to the outer end of the side insert plate. The number of side insert holes is the same as the number of side inserts and they correspond one-to-one. The bottom plate of the inner box is provided with side insert holes for insertion into the side inserts. After the side panels, side top plates and side inserts are folded along the creases, the side inserts are inserted into the side insert holes for fixation.

[0009] Furthermore, a side support plate is fixedly connected to the upper end of the crease between the side panel and the inner bottom panel. A support plate insert is fixedly connected to the upper end of the side support plate. A support plate insertion hole is opened on the side top panel for insertion into the support plate insert.

The support plate insert is used to enhance the overall pressure resistance of the packaging box.

[0010] Furthermore, the end cardboard includes an end circumference plate, an end top plate, and an end insert plate. The end circumference plate, the end top plate, the end insert plate, and the inner box bottom plate are fixedly connected sequentially from the outside to the inside, and there are creases between adjacent cardboard pieces.

[0011] Furthermore, an end plug is fixedly connected to the outer end of the end plate, and an end plug hole is opened on the bottom plate of the inner box to be inserted into the end plug. After the end plate, end top plate and end plate are folded along the crease, the end plug is inserted into the end plug hole for fixation.

[0012] Furthermore, the outer end of the side plate is fixedly connected with two sets of symmetrical side auxiliary fixing blocks. The outer end of the side auxiliary fixing blocks has an arc-shaped structure. The end plate and the end top plate are provided with auxiliary fixing holes for insertion with the side auxiliary fixing blocks. When the end plate, the end top plate and the end plate are folded along the crease, the end blocks are inserted into the end holes for fixing. After the side plate, the side top plate and the side plate are folded along the crease, the side blocks are inserted into the side holes for fixing. Then, the side auxiliary fixing blocks are inserted into the end plate for fixing.

[0013] Furthermore, the outer box includes an outer box bottom plate, an outer box top plate, and an outer box side plate. There are two sets of outer box side plates. The outer box side plates, outer box top plate, outer box side plates, and outer box bottom plate are fixedly connected in sequence, and there are creases between adjacent cardboard pieces. After the outer box side plates, outer box top plate, outer box side plates, and outer box bottom plate are folded and fixed along the creases, a hollow cubic structure is formed.

[0014] Furthermore, the bottom of the top plate of the outer box is fixedly connected with multiple sets of left and right symmetrical outer box fixing blocks. The number of support plate insertion holes is the same as the number of sets of outer box fixing blocks and they correspond one-to-one. The side top plate is provided with support plate insertion holes for insertion into the outer box fixing blocks. After the inner box is assembled, the outer box fixing blocks are inserted into the support plate insertion holes for fixation.
