Description

Technical Field

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

[0002] Paper packaging boxes are containers used for product packaging, made from natural plant fibers through multiple processes including pulping, molding, drying, and surface treatment. Structurally, they typically consist of a box body, lid, and base, and can be designed into various shapes to suit different product forms, such as common cuboids and cubes, as well as cylinders and irregular shapes. The materials used in their production are diverse, commonly including corrugated cardboard, cardboard, and kraft paper. Furthermore, paper packaging boxes offer environmental advantages such as recyclability and biodegradability, aligning with current green development concepts, and are widely used in numerous industries including food, daily chemicals, electronics, and clothing.

[0003] However, current paper packaging boxes have some significant shortcomings in existing technology. Their relatively simple structure and lack of splicing mechanisms mean that the size of the paper packaging box is fixed in actual use. This limitation means that when dealing with products of varying quantities and volumes, the internal space of the paper packaging box cannot be changed by splicing to meet actual usage needs. For example, in the packaging process for e-commerce goods, when there are too many items to store, the limited space of a single paper packaging box necessitates increasing the number of boxes, which not only increases packaging costs but may also lead to low packaging efficiency. Conversely, when storing fewer items, it results in wasted internal space and reduced space utilization.

[0004] Furthermore, existing paper packaging boxes are prone to shaking and collapsing when stacked due to the lack of effective fixing and connecting structures, affecting the safety of warehousing and transportation. Moreover, for scenarios requiring temporary adjustments to packaging space, such as product display packaging at trade shows or product packaging for temporary promotional activities, existing paper packaging boxes cannot be quickly and flexibly adjusted, failing to meet actual usage needs.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, a splicing mechanism is used to fix the upper box and the middle box, the middle boxes and each other, and the middle box and the lower box together. When storing more items, the number of middle boxes can be increased and connected by the splicing mechanism, thereby expanding the internal space of the packaging box without increasing the number of boxes, thus reducing packaging costs.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] like Figure 1 - Figure 4 As shown, a splicing paper packaging box includes an upper box body 1 and a lower box body 2, with several intermediate boxes 3 between the upper box body 1 and the lower box body 2. The upper box body 1 and the intermediate boxes 3, the intermediate boxes 3 and the intermediate boxes 3, and the intermediate boxes 3 and the lower box body 2 are all fixedly connected together by a splicing mechanism 4. The splicing mechanism 4 includes a splicing frame 7, side plates 9, a flip plate 11, a pressing plate 18, a limiting rod 20, a fixing rod 21, and a spring 22. A set of symmetrical side plates 9 are fixedly connected to the four sides of the outer wall of the splicing frame 7. The flip plate 11 is movably connected between the side plates 9 by rotating rods 12 on both sides at one end. The pressing plate 18 is movably connected to the inside of the flip plate 11 by the fixing rod 21 on the outer side wall. The spring 22 is sleeved on the outside of the fixing rod 21. The limiting rod 20 is fixedly connected to the inner side wall of the pressing plate 18.

[0022] like Figure 2 As shown, positioning rods 5 are fixedly installed on the opposite surfaces of the upper box 1 and the lower box 2, as well as at the four corners of the top and bottom surfaces of the middle box 3. These positioning rods 5 are used to insert into the positioning holes 8 on the splicing frame 7 during assembly, serving as a preliminary positioning function to ensure the accurate relative position of each box during assembly. Square tubes 6 are fixedly installed on the four sides of the outer walls of the upper box 1, the lower box 2, and the middle box 3. The square tubes 6 on the four sides of the outer wall of the middle box 3 are a symmetrical set. These square tubes 6 are used to cooperate with the limiting rods 20 on the splicing frame 7 to achieve further fixed connection between each box.

[0023] like Figure 3 As shown, the top four corners of the splicing frame 7 are respectively provided with positioning holes 8 corresponding to the positioning rods 5. During the splicing process, the positioning rods 5 are inserted into the positioning holes 8. Through this cooperation method, the movement of the upper box 1, the lower box 2 and the middle box 3 in the horizontal direction is restricted, which plays a role in positioning and initial fixation, so that each box can be accurately spliced ​​together, avoiding misalignment during splicing. At the same time, it also provides a good foundation for further fixation by the limiting rods 20 and the square tube 6, and enhances the overall stability of the paper packaging box.

[0024] like Figure 3 and Figure 4As shown, a set of left-right symmetrical side plates 9 are fixedly installed on the four sides of the outer wall of the splicing frame 7, and a set of up-down symmetrical rotating holes 10 are opened on the side wall of the side plate 9. The rotating holes 10 are used to install the rotating rod 12 on the flip plate 11, so that the flip plate 11 can rotate between the side plates 9 with the rotating rod 12 as the axis, providing a movable basis for splicing and disassembly operations.

[0025] like Figure 3 and Figure 4 As shown, rotating rods 12 are fixedly installed on the inner side walls of the flap 11, and the rotating rods 12 are movably installed in the rotating holes 10, so that the flap 11 can rotate. A movable opening 13 is provided below the front wall of the flap 11 to ensure that the square cylinder 6 can enter the movable opening 13. A vertical opening 14 is provided above the front wall of the flap 11 to provide space for the pressing plate 18. A through opening 15 communicating with the movable opening 13 is provided on the inner bottom surface of the vertical opening 14 to ensure that the limiting rod 20 can pass through the through opening 15 and be inserted into the square cylinder 6 in the movable opening 13. Sliding openings 16 are provided on the inner side walls of the vertical opening 14 to cooperate with the slider 19 to achieve sliding operation. A through hole 17 is also provided on the inner top surface of the vertical opening 14 to guide the fixed rod 21.

[0026] like Figure 3 and Figure 4 As shown, sliders 19 are fixedly installed on both sides of the pressing plate 18, and the sliders 19 are movably installed in the sliding opening 16. A fixing rod 21 is fixedly installed on the outer side of the pressing plate 18, and the fixing rod 21 is inserted into the through hole 17. A spring 22 is fitted outside the fixing rod 21, and the spring 22 is also fixedly installed between the opposing walls inside the pressing plate 18 and the vertical opening 14. A limiting rod 20 is fixedly installed on the inner side wall of the pressing plate 18, and the limiting rod 20 passes through the through opening 15 and is inserted into the square tube 6. Pressing the pressing plate 18 causes the sliders 19 to slide in the sliding opening 16, and causes the fixing rod 21 to pass through the through hole. 17. The spring 22 is forced to contract until the limiting rod 20 moves from the movable opening 13 into the through opening 15. Then, the flip plate 11 is flipped so that the corresponding square tube 6 is placed in the movable opening 13. The pressing force on the pressing plate 18 is released, so that the spring 22 elastically recovers and extends. Then, the pressing plate 18 is pushed so that the limiting rod 20 passes through the through opening 15 and is inserted into the square tube 6. The upper box 1, the middle box 3 and the lower box 2 can be spliced ​​and fixed together for use. By adding or removing the middle box 3 between the upper box 1 and the lower box 2 in this way, the internal space size of the paper packaging box can be changed according to actual use needs.

[0027] The specific operating principle of the splicing mechanism 4 in conjunction with the upper box 1, lower box 2, and middle box 3 is as follows:

[0028] Install the splicing frame 7 onto the top surface of the lower box 2, and insert the positioning rods 5 at the four corners of the top surface of the lower box 2 into the positioning holes 8 on the splicing frame 7. Then install the middle box 3 onto the top surface of the splicing frame 7, and insert the positioning rods 5 at the four corners of the bottom surface of the middle box 3 into the positioning holes 8. Stack several middle boxes 3 vertically according to actual needs, and install the splicing frame 7 between adjacent middle boxes 3 during the stacking process. Then install the upper box 1 onto the top surface of the uppermost splicing frame 7 through the positioning rods 5, and manually press the front wall of the flip plate 11. The protruding pressing plate 18 will move within the vertical opening 14, and the sliders 19 on both sides of the pressing plate 18 will slide within the sliding opening 16. The pressing plate 18 will push the fixing rod 21 through the through hole 17, and force the spring 22 fitted outside the fixing rod 21 to tighten until the limiting rod 20 installed on the inner wall of the pressing plate 18 moves from the movable opening 13 into the through opening 15. After that, the pressing force on the pressing plate 18 remains unchanged, and the flip plate 11 is flipped upward. When flipping, the rotating rods 12 on the two inner walls of the flip plate 11 will rotate on the opposite side of the splicing frame 7. The plate 9 is rotated within the rotating hole 10 on its side wall until the flap 11 can no longer be flipped. The corresponding square tube 6 is then placed in the movable opening 13 on the front wall of the flap 11. The pressure on the pressing plate 18 is then released, causing the spring 22 to elastically extend and push the pressing plate 18 inwards until the limiting rod 20 passes through the through-hole 15 and inserts into the square tube 6 within the movable opening 13. This allows for the rapid assembly and combination of the upper box 1 and the middle box 3, the middle box 3 and the middle box 3, and the middle box 3 and the lower box 2. Therefore, when storing more items, the number of intermediate boxes 3 can be increased to expand the internal space of the paper packaging box without increasing the number of paper packaging boxes, thus reducing packaging costs. When storing fewer items, the number of intermediate boxes 3 can be reduced to shrink the space of the paper packaging box, improving space utilization. The number of intermediate boxes 3 can be increased or decreased according to actual usage needs to flexibly change the internal space size of the paper packaging box, solving the problem of fixed space in existing paper packaging boxes and meeting the actual usage needs of the paper packaging box.
