Description

Technical Field

[0001] This utility model relates to the field of corrugated paper packaging box technology, specifically a corrugated paper packaging box with adjustable space. Background Technology

[0002] Corrugated cardboard boxes are widely used in product transportation and sales packaging due to their advantages such as low cost, light weight, and environmental recyclability. However, existing corrugated cardboard boxes have a long-standing inherent drawback: their internal space is fixed. When the internal space of the box is larger than the packaged items, the items are prone to shaking and collisions during transportation, leading to damage. Furthermore, a large amount of cushioning material (such as foam or bubble wrap) is required to protect the items. Therefore, we propose a corrugated cardboard box with adjustable space to solve these problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an embodiment of this utility model proposes a corrugated cardboard packaging box with adjustable space, including a box body 1 and a box lid 2. The box body 1 is fitted with a reinforcing frame 8, which is made of plastic. The plastic reinforcing frame 8 on the outside of the box body 1 provides stable support for the overall structure, thereby improving the overall anti-deformation performance of the packaging box during transportation. The box lid 2 is snapped onto the top of the box body 1. The box body 1 is provided with an adjustable component 3 for adjusting the space size.

[0027] The adjustment assembly 3 includes two support frames 31 fixed inside the housing 1. Each support frame 31 is rotatably connected to a bidirectional lead screw 32 via bearings. The upper and lower ends of the two bidirectional lead screws 32 are threadedly connected to movable plates 33 that are adapted to their surface threads. Each side wall of the movable plate 33 is rotatably connected to a push plate 34 via a pin. Correspondingly, the two push plates 34 are rotatably connected to an adjustment plate 35 via a pin. Each side wall of the adjustment plate 35 is fixed with a positioning plate 36. Each top of the bidirectional lead screw 32 is fixed with a knob 37. The entire adjustment assembly 3 is made of plastic, which is lightweight and low in cost.

[0028] The working principle and usage process of this utility model are as follows: When it is necessary to adjust the internal space of the box 1, by rotating the knob 37 at the top of the bidirectional lead screw 32, the bidirectional lead screw 32 can be driven to rotate around the bearing on the support frame 31 fixed inside the box 1. Since the threads at the upper and lower ends of the bidirectional lead screw 32 are opposite and are matched with the threaded fit on the surface of the moving plate 33, when the bidirectional lead screw 32 rotates, the moving plates 33 at its upper and lower ends will move synchronously in the opposite direction along the lead screw.

[0029] During the movement of the movable plate 33, the push plate 34 connected to it is rotated by the pin shaft. The two corresponding push plates 34 act together on the adjusting plate 35 through the pin shaft. At this time, the adjusting plate 35 can be pushed to move smoothly towards the center of the box 1. After the adjusting plate 35 moves, it will drive the positioning plate 36 fixed on its side wall to move simultaneously. Therefore, when the positioning plates 36 on both sides move to the middle position, the inside of the box 1 can be adjusted.

[0030] like Figure 1 and Figure 3 As shown, in some embodiments, a ventilation assembly 4 is provided on the lid 2. The ventilation assembly 4 includes a limiting frame 41 fixed at the top opening of the lid 2. Two sealing strips are fixed on the limiting frame 41, thereby enhancing the tightness of its fit with the sealing plate 42. The top of the limiting frame 41 is slidably connected to two sealing plates 42. A dustproof net 43 is fixed inside the limiting frame 41. A cathode magnetic strip 44 is fixed on one side wall of one sealing plate 42, and an anode magnetic strip 45 is fixed on one side wall of the other sealing plate 42. The cathode magnetic strip 44 and the anode magnetic strip 45 attract each other, facilitating a tighter fit between the two sealing plates 42. The top of each sealing plate 42 is fixed with an anti-slip plate 46 for easy operation and movement. When the plate 42 moves, the anti-slip plate 46 can enhance the friction of the hand, thus achieving an anti-slip effect. In use, the limiting frame 41 is fixed at the opening at the top of the box cover 2, providing an installation base and limiting support for the entire ventilation structure. When ventilation is needed inside the box, the user can open the sealing plate 42 by operating the anti-slip plate 46. At this time, the cathode magnetic strip 44 and the anode magnetic strip 45 will separate, and the opening on the box cover 2 that was originally blocked will gradually open. At this time, the air inside and outside the box can circulate through the opening. The dustproof net 43 inside the limiting frame 41 can block the external dust from entering the box 1 during the ventilation process, avoiding contamination of the stored items. In addition, the components of the entire ventilation assembly 4 are made of plastic, which is lightweight and low in cost.

[0031] When ventilation is not required, push the anti-slip plate 46 to move the two sealing plates 42 closer to each other along the track until the cathode magnetic strip 44 and the anode magnetic strip 45 attract each other. At this time, the two sealing plates 42 are tightly fitted together, which can completely seal the opening and thus achieve the sealing of the space inside the box.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, four elastic bands 5 are fixed to the top of the lid 2, and hook and loop fasteners 6 are fixed to the lower surface of each elastic band 5. Hook and loop fasteners 7 that cooperate with the hook and loop fasteners 6 are fixed to both sides of the box body 1. Through the cooperation of the elastic bands 5, the hook and loop fasteners 6 and the hook and loop fasteners 7, when the lid 2 is snapped onto the top of the box body 1, the lid 2 can be fixed by operating the elastic bands 5 without the need to use tape for bonding.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
