Description

Technical Field

[0001] This utility model relates to the field of paper packaging boxes, and in particular to a compression-resistant paper packaging box. Background Technology

[0002] In the current packaging industry, paper packaging boxes have become the mainstream packaging choice for food, electronics, cosmetics, and pharmaceuticals due to their significant advantages such as environmental friendliness, biodegradability, lightweight and easy processing, and low cost. With the rapid development of e-commerce logistics, packaging boxes need to withstand greater stacking pressure and complex external impacts during transportation. However, existing paper packaging boxes still have shortcomings in their compression resistance. Especially during transportation and storage, packaging boxes are easily subjected to external pressure, leading to deformation or even damage. Compared to the corners of paper packaging boxes, the middle of the side walls, lacking supporting components, is more prone to denting and damage after being compressed. This problem not only affects the aesthetics of the packaging box but may also damage the products inside. Therefore, there is an urgent need to design a compression-resistant paper packaging box to solve the above problems. Utility Model Content

[0003] The main objective of this invention is to provide a compression-resistant paper packaging box, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A compression-resistant paper packaging box includes a paper packaging box body. A top support frame is installed inside the paper packaging box body. Four folding support members are symmetrically installed on the top support frame. Each folding support member consists of a support cross plate, a fixing rod, and a handle. The support cross plate is rotatably mounted on the top support frame. The fixing rod is inserted into the top support frame and the support cross plate. The handle is fixedly installed at the upper end of the fixing rod. A bottom support frame is fixedly installed inside the paper packaging box body and at the lower end of the top support frame. The bottom support frame consists of support vertical frames and L-shaped support frames. Four support vertical frames and four L-shaped support frames are provided. The four support vertical frames and four L-shaped support frames are interconnected to form a whole.

[0006] Preferably, the supporting vertical frame and the L-shaped supporting frame on the bottom support frame are fixedly connected. The L-shaped supporting frame contacts the bottom wall and side wall of the paper packaging box body. The supporting vertical frame is fixedly installed at the lower end of the top support frame and contacts the middle of the side wall of the paper packaging box body.

[0007] Preferably, the top support frame has four first storage slots symmetrically formed on its two side walls, each containing a fixed shaft. Four first insertion holes are also symmetrically formed on the two side walls, allowing the top support frame to pass vertically through them and communicating with the first storage slots. The top support frame also has four second storage slots symmetrically formed on its other two side walls, with four second insertion holes symmetrically formed on these same walls. These second insertion holes also allow the top support frame to pass vertically through them and communicate with the second storage slots.

[0008] Preferably, the support plate on the folding support member has a shaft hole and a fixing hole. The support plate is rotatably mounted on a fixed shaft fixedly installed in the first storage groove through the shaft hole. The support plate also has an opening slot.

[0009] Preferably, the fixing rod is inserted into a fixing hole opened on the support plate, and the handle is located above the support plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] By incorporating a top support frame and a bottom support frame within the main body of the paper packaging box, the box's resistance to compression is enhanced, effectively dispersing external pressure and preventing the middle of the box's side walls from collapsing due to lack of support. A folding support piece is installed on the top support frame; the support plate of this piece can be rotated and adjusted. When placing or removing items from the box, the support plate can be completely folded into the first storage slot on the top support frame, preventing obstruction. During transportation and storage, the support plate can be unfolded, providing support for the box and significantly improving its resistance to compression in transportation and storage environments, while also ensuring ease of use.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a crush-resistant paper packaging box includes a paper packaging box body 1. A top support frame 2 is installed inside the paper packaging box body 1. Four folding support members 3 are symmetrically installed on the top support frame 2. Each folding support member 3 consists of a support cross plate 12, a fixing rod 16, and a handle 17. The support cross plate 12 is rotatably mounted on the top support frame 2. The fixing rod 16 is inserted into the top support frame 2 and the support cross plate 12. The handle 17 is fixedly installed on the upper end of the fixing rod 16. The paper packaging box body 1 is located within the top support frame 2. A bottom support frame 4 is fixedly installed at the lower end. The bottom support frame 4 consists of a support vertical frame 5 and an L-shaped support frame 6. There are four support vertical frames 5 and four L-shaped support frames 6. The four support vertical frames 5 and the four L-shaped support frames 6 are connected to each other to form a whole. When in use, first unfold the paper packaging box body 1 and fix its shape to ensure that the top support frame 2 and the bottom support frame 4 are installed in place, so that the L-shaped support frame 6 contacts the bottom wall and side wall of the paper packaging box body 1, and the support vertical frame 5 contacts the middle of the side wall of the paper packaging box body 1 to enhance the compression resistance.

[0019] Specifically, the vertical support frame 5 and the L-shaped support frame 6 on the bottom support frame 4 are fixedly connected. The L-shaped support frame 6 contacts the bottom wall and side wall of the paper packaging box body 1. The vertical support frame 5 is fixedly installed at the lower end of the top support frame 2, and the vertical support frame 5 contacts the middle of the side wall of the paper packaging box body 1. Four first storage slots 8 are symmetrically opened on the two side walls of the top support frame 2. A fixed shaft 7 is fixedly installed in the first storage slot 8. Four first insertion holes 9 are symmetrically opened on the two side walls. The first insertion holes 9 penetrate the top support frame 2 vertically. At the same time, it is interconnected with the first storage slot 8. Four second storage slots 10 are symmetrically opened on the other two side walls of the top support frame 2, and four second insertion holes 11 are symmetrically opened on the two side walls. The second insertion holes 11 pass through the top support frame 2 vertically and are interconnected with the second storage slots 10. By setting the top support frame 2 and the bottom support frame 4 inside the paper packaging box body 1, the compression resistance of the paper packaging box body 1 can be improved, the external pressure can be effectively distributed, and the middle of the side wall of the paper packaging box body 1 can be prevented from denting due to lack of support.

[0020] Specifically, the support plate 12 on the folding support member 3 has a shaft hole 13 and a fixing insertion hole 14. The support plate 12 is rotatably mounted on the fixing shaft 7 fixedly installed in the first storage groove 8 through the shaft hole 13. The support plate 12 also has an opening groove 15. The fixing insertion rod 16 is inserted into the fixing insertion hole 14 on the support plate 12. The handle 17 is located above the support plate 12. By setting the folding support member 3 on the top support frame 2, the support plate 12 of the folding support member 3 can be rotated and adjusted. That is, when it is necessary to put items into or take items out of the paper packaging box body 1, the support plate 12 can be completely folded into the first storage groove 8 on the top support frame 2, thereby avoiding obstructing the taking and putting of items. When transporting and storing, the support plate 12 can be unfolded, which can provide support for the paper packaging box body 1, significantly improving the compression resistance of the paper packaging box body 1 in the transportation and storage environment, while also taking into account the convenience of use.

[0021] When it is necessary to put or take out items into or from the paper packaging box body 1, first pull out the fixing rod 16 from the second insertion hole 11 and the fixing insertion hole 14 by pulling out the handle 17, thereby releasing the fixation of the support plate 12. Then, rotate and fold the support plate 12 into the first storage slot 8 around the fixing shaft 7. Then, insert the fixing rod 16 into the first insertion hole 9 and the fixing insertion hole 14, thereby fixing the support plate 12 in the first storage slot 8, thus preventing the support plate 12 from obstructing the taking out or putting in items. During the transportation or storage of items, unfold the support plate 12 as follows: Figure 1The method is as follows: first, pull the fixing rod 16 out of the first insertion hole 9 and the fixing insertion hole 14; then rotate the support plate 12 around the fixing shaft 7, so that one end of the support plate 12 enters the second storage slot 10; finally, insert the fixing rod 16 into the second insertion hole 11 and the fixing insertion hole 14 to fix the support plate 12. At this time, the support plate 12 provides additional support for the paper packaging box body 1 to prevent the side wall from being deformed by pressure. By adjusting the state of the folding support 3, it is not only convenient to put and take out items, but also significantly improves the compression resistance of the packaging box.
