Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a foldable corrugated paper packaging box. Background Art

[0002] Packaging boxes are widely used in daily life. Placing products inside packaging boxes can protect the products and facilitate transportation. At the same time, in order to protect the environment, paper packaging boxes are increasingly recognized by the market. They can be recycled after use to avoid unnecessary waste and pollution to the environment. In addition, corrugated paper is widely used as the production material of packaging boxes because of its low cost, light weight, high strength and simple processing.

[0003] The structure of a traditional corrugated paper box is relatively simple, usually consisting of a bottom plate, side walls and a lid, all of which are made of corrugated paper. Due to the good flexibility of corrugated paper, it can withstand a certain degree of deformation without breaking. This simple structure allows the box to be folded and unfolded relatively easily, but this simple structure makes the overall bearing capacity of the corrugated paper box low, and the box body is easily deformed when squeezed, which not only affects the overall appearance of the corrugated paper packaging box, but also causes damage to the items inside the corrugated paper packaging box. For this reason, we propose a foldable corrugated paper packaging box. Utility Model Content

[0004] The main purpose of the utility model is to provide a foldable corrugated paper packaging box, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foldable corrugated paper packaging box, comprising a bottom plate, a side plate and a top cover, wherein storage grooves are provided on both sides of the upper surface of the bottom plate, and reinforcement rods are vertically provided on both sides of the inner cavity of the storage groove, and both sides of the bottom end of the reinforcement rod are rotatably connected with a rotating connecting shaft, and the outer ends of the rotating connecting shaft are detachably connected to the two sides of the inner cavity of the storage groove, and a sleeve hole is provided on the upper surface of the top cover at a position matching the reinforcement rod, and the top cover is sleeved on the top end of the fixing rod through the sleeve hole, and the top end of the reinforcement rod is threadedly connected with a hand-tightened bolt.

[0006] Preferably, the fixing rod comprises a sleeve rod, an extension rod and a threaded hole, the extension rod is threadedly connected to the upper end of the sleeve rod inner cavity, the surface of the extension rod is provided with threads, and the top of the extension rod is provided with a threaded hole compatible with a hand-tightened bolt.

[0007] Preferably, a waterproof membrane is adhesively connected to the surface of the side panel.

[0008] Preferably, the surface of the waterproof membrane is adhesively connected with an anti-tear membrane.

[0009] Preferably, the surface of the side panel is provided with folds for folding the side panel, and there are four groups of folds.

[0010] Preferably, a slot matching the side panel is provided at the bottom end of the inner cavity of the bottom panel.

[0011] Preferably, the extension rod can be screwed into the interior of the sleeve rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model arranges a bottom plate, a slot, a reinforcing rod, a side plate, a fold, a top cover, a sleeve hole, and the threaded holes and hand-tightening bolts cooperate with each other. When the corrugated packaging box is in use, after the side plates are unfolded, the bottom ends of the side plates are directly clamped into the slots in the inner cavity of the bottom plates, and the outer side walls of the bottom ends are fitted with the inner walls of the slots. At the same time, the top cover is sleeved on the top end of the reinforcing rod through the sleeve holes sleeved on the surface, and is moved downward along the reinforcing rod to be clamped on the top end of the side plate. The top cover is threadedly connected to the threaded holes opened on the top end of the reinforcing rod from the upper end of the top cover by means of hand-tightening bolts, so that the top cover is fixed to the top of the side plates. During transportation, the reinforcing rods can effectively improve the compressive resistance of the box body, and will not be easily deformed when squeezed, and will not be easily deformed when squeezed to affect the aesthetics. The items stored inside can also be effectively protected during use. At the same time, the top cover can be quickly removed by operating in reverse, and the side panels can be folded through the creases to effectively reduce the area occupied by the box. The reinforcement rod can be rotated inward so that the reinforcement rod can be stored in the storage groove opened on the upper surface of the base, which is convenient for assembly when used again. There is no need to use tape or nails to fix it, which fully complies with the guidelines of energy conservation, emission reduction, low carbon and environmental protection, and saves resources.
