Technical Field
[0001] This utility model relates to the field of corrugated cardboard box technology, and in particular to a corrugated cardboard box with a supporting inner lining. Background Technology
[0002] Corrugated cardboard boxes are an extremely common form of packaging in daily life and commerce. Due to their excellent protective performance, ease of processing and production, and good recyclability, they are widely used in the transportation and storage of various goods. Traditional corrugated cardboard boxes mainly rely on single or multiple layers of corrugated cardboard for their physical structure. To further enhance the protection of the goods inside, some cardboard boxes will have an inner lining that conforms to the shape of the product. Taking the "Inner Lining Structure of a Carton Packaging" application number CN202321791427.9 as an example, this structure includes an inner lining panel and an inner ring. Both ends of the inner lining panel are equipped with locking blocks. Four inner lining panels are joined in pairs through these locking blocks to form an inner lining frame. The inner ring is placed inside the inner lining frame, and the two are concentric, with the inner ring located at the lower end of the inner lining frame. A spring is provided between the inner ring and the side wall of the inner lining panel, and multiple locking teeth are distributed at equal angles on the inner wall of the inner ring. The inner lining panel uses a honeycomb corrugated paper core to enhance structural strength, and a corrugated plate is provided on its outer side, allowing the inner lining panel to effectively withstand impact when the carton is subjected to impact, reducing damage to fragile items. The inner lining panel surrounds the fragile container, protecting it from above, while the inner ring supports the fragile container. Simultaneously, the spring provides cushioning for the inner ring, effectively protecting the fragile container. However, the protective solutions presented in the aforementioned patent documents mainly rely on the inner ring and its locking teeth to achieve the protective function. But this locking ring structure is fixed and has obvious limitations. It cannot flexibly adjust the fit and protective position according to the size, shape and vulnerable parts of different products, making it difficult to meet the personalized protection needs of diverse products. In actual application scenarios, the protective effect is greatly reduced.
[0003] Therefore, how to obtain a corrugated cardboard box with a supporting lining that can better stabilize the structural strength of the cardboard box body and enhance its torsional resistance has become an urgent and realistic need. Utility Model Content

[0012] The beneficial effects of this utility model are: the corrugated cardboard box can rely on the internal load-bearing structure as a load-bearing auxiliary, and together with the buffer components, form a flexible internal protection. When in use, it can be adjusted according to the shape of the stored items. The buffer components limit the movement range of the items. Furthermore, for the cardboard box body, the filling structure between the load-bearing devices can better stabilize the structural strength of the cardboard box body and enhance the torsional resistance of the cardboard box body.

[0021] The present invention will be further described below with reference to the accompanying drawings: Example
[0022] like Figures 1-6As shown, this embodiment provides a corrugated cardboard box with a supporting lining, including a box body 1. A top cover plate 101 is connected to the top edge of the box body 1. A supporting structure 2 is fixed to the inner wall of the box body 1. The supporting structures 2 are arranged in pairs near the corners of the box body 1. A filling structure 3, which is snapped between the supporting structures 2, is installed at the corners of the box body 1. The supporting structure 2 includes a horizontal portion 201 fixed to the inner wall of the box body 1. A bend plate 202 is fixed to the horizontal portion 201. One end of the bend plate 202 extends towards the adjacent corner of the box body 1, and the bend plate 202... The box has two support holes 203. A reinforcing plate 204 is fixed to the bottom of the corner plate 202. The support structures 2 are arranged at different heights on the inner wall of the carton body 1. A buffer assembly 4 is installed between the support structures 2 at the same height. A top buffer pad 102 is fixed on the top cover plate 101. A bottom buffer pad 103 is provided at the bottom inside the carton body 1. This can enhance the buffer protection effect on the items. Items can be placed on the bottom buffer pad 103 first. After the top cover plate 101 is closed, the top buffer pad 102 can protect the top of the items.
[0023] The filling structure 3 includes a filling plate 301 located between the horizontal part 201 and the corner plate 202. The filling plate 301 is provided with a corresponding fitting notch 302. A front panel 303 and a support strip 304 are fixedly connected between the filling plates 301 of different heights. The front panel 303 is located between the corner plates 202, which can help limit the position of the filling structure 3. The filling structure 3 can play a good structural support role.
[0024] The buffer assembly 4 includes a snap-fit plate 401. The bottom of the snap-fit plate 401 is fixed with a plug post 402 that can be inserted into the bearing hole 203. A side connecting plate 403 is fixed on the side wall of the snap-fit plate 401. A contact member 404 is installed between the side connecting plates 403, so that the position of the snap-fit plate 401 can be flexibly adjusted.
[0025] The contact component 404 is made of corrugated paper strip or low-density polyethylene strip. This allows the deformable characteristics of the contact component 404 to better fit and wrap around the outside of the item, thus better restricting the position of the internal item.
[0026] This corrugated cardboard box can rely on the internal load-bearing structure 2 as a load-bearing auxiliary, and together with the cushioning component 4, it can form a flexible internal protection. When in use, it can be adjusted according to the shape of the stored items. The cushioning component 4 can limit the movement range of the items. Furthermore, for the cardboard box body 1, the filling structure 3 between the load-bearing devices can better stabilize the structural strength of the cardboard box body 1 and enhance the torsional resistance of the cardboard box body 1. Example
[0027] like Figure 7As shown, this embodiment improves the fixing method of the contact component 404 based on embodiment 1. The contact component 404 is connected to the side connecting plate 403 through the clamping plate device 5. The clamping plate device 5 includes clamping plate members 501 located on both sides of the side connecting plate 403. The clamping plate members 501 are provided with mounting holes that penetrate the side connecting plate 403. The clamping plate members 501 on both sides of the side connecting plate 403 are fixedly connected by fixing bolts 502. One side of the clamping plate member 501 is provided with an external protrusion 503, which facilitates the replacement of contact components 404 of different specifications. Friction ridges 504 are fixed on the side wall of the external protrusion 503. One end of the contact component 404 is located between the external protrusions 503. The thickness of the side connecting plate 403 is less than the thickness of the contact component 404, which facilitates the fixing of the contact component 404.
[0028] This allows the material or length of the contact component 404 to be changed according to the shape requirements of the stored items. In actual use, by continuously wrapping the contact component 404 around the outer wall of the item, the effect of auxiliary fixation and buffer protection is achieved.
