Description

Technical Field

[0001] The present application relates to the field of packaging containers, and in particular to a foldable packaging box. Background Art

[0002] With the development of economy and the popularization of logistics, people's demand for packaging boxes has also increased. Packing boxes are the main means of containing products. Traditional packaging boxes are often integrated structures, which take up a lot of space when stored and cause waste of space resources; therefore, a foldable packaging box is needed.

[0003] Existing detachable packaging boxes are generally disassembled into multiple separate panels for transportation. However, in the actual transportation process, the stacked panels may become scattered due to the bumps of the transportation vehicle. Therefore, additional fastening devices are generally required to fix the stacked panels during transportation, which will increase the transportation cost. In addition, traditional fastening devices generally use cable ties for bundling, which may leave marks on the edges of the panels during transportation, affecting the use of the panels. Therefore, there is an urgent need for a foldable packaging box that does not require additional bundling. Utility Model Content

[0004] One of the purposes of the present application is to provide a foldable packaging box that can solve at least one defect in the above-mentioned background technology.

[0012] Preferably, the splicing board includes a bottom board and a side board. Support blocks and elastic members are arranged on the bottom board, and the support blocks are rotatably mounted on the bottom board through the elastic members; support holes are arranged on the side board. When the side board is combined with the bottom board, the support holes are adapted to cooperate with the support blocks for clamping.

[0026] Next, in combination with specific embodiments, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be combined arbitrarily to form new embodiments.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0029] The terms "including" and "having" in the description and claims of the present application, as well as any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0030] One preferred embodiment of the present application is as follows Figure 1 and Figure 2As shown in the figure, a foldable packing box includes splicing plates 1 and connecting rods 100. Multiple splicing plates 1 can be spliced together by connecting rods 100 to form a packing box. During the superposition transportation process, in order to prevent relative displacement between the splicing plates 1 due to external forces such as bumps, positioning holes 200 are provided on the plate surfaces of the splicing plates 1. When the splicing plates 1 are stacked together, the positioning holes 200 on each splicing plate 1 are aligned. The disassembled connecting rods 100 are inserted into the positioning holes 200 to ensure the stability of the stacked transportation of the splicing plates 1.

[0031] It should be known that there are various ways to set the positioning holes 200. For the convenience of understanding, the following will be described by taking two ways as examples.

[0032] The first way: The positioning holes 200 are arranged vertically, and the connecting rods 100 can be vertically inserted into the positioning holes 200.

[0033] The second way: The positioning holes 200 are arranged obliquely, and the connecting rods 100 can be obliquely inserted into the positioning holes 200.

[0034] It can be understood that during the actual transportation process, the directions of the bumping forces received by the splicing plates 1 are in multiple directions, which can be mainly divided into vertical component forces and horizontal component forces; the vertical component forces can drive the splicing plates 1 to have vertical upward and downward movements, and the horizontal component forces can drive the splicing plates 1 to have horizontal shaking or deflection. For the first way mentioned above, the splicing plates 1 may move upward and downward along the axial direction of the connecting rods 100, or may rotate around the connecting rods 100; of course, multiple positioning holes 200 can be provided on a single splicing plate 1 to realize the insertion of multiple connecting rods 100 to avoid the deflection of the splicing plates 1. For the second way mentioned above, the inclination of the positioning rods 100 can generate limitations in the vertical, horizontal, and horizontal circumferential directions on the splicing plates 1, thereby ensuring the transportation stability of the splicing plates 1. Therefore, in this embodiment, the second way of setting the positioning holes 200 is preferably adopted.

[0035] In this embodiment, the inclination angle of the positioning holes 200 determines the installation angle of the connecting rods 100; the inclination angle of the positioning holes 200 can refer to the vertical direction or the horizontal direction. Taking the horizontal direction as an example, if the inclination angle of the positioning holes 200 is too large, that is, the insertion of the connecting rods 100 will tend to be vertical, and the vertical limiting ability is relatively poor; if the inclination angle of the positioning holes 200 is too small, it may not be possible to penetrate all the splicing plates 1 due to the influence of the stacked thickness of the splicing plates 1, and the processing difficulty is relatively large; therefore, the inclination angle of the positioning holes 200 can be set between 30° and 60°, and the preferred inclination angle is 45°.

[0036] In this embodiment, since the stress on the splicing plate 1 is complex during the superposed transportation, the splicing plate 1 may also move along the axial direction of the inclined connecting rod 100. To further ensure the transportation stability of the splicing plate 1, the structure of the positioning hole 200 can be further optimized, and there are various optimization methods. The following will be described in detail through two specific examples.

[0037] Example 1: As Figure 1 and Figure 3 shown, a plurality of positioning holes 200 can be formed in the splicing plate 1, but at least two of the positioning holes 200 have opposite inclination directions, so that the connecting rods 100 inserted into the two positioning holes 200 can limit each other. Taking the inclination angle of 45° as an example, the axis of one connecting rod 100 is perpendicular to the axis of the other connecting rod 100, so that the limiting forces generated by the two connecting rods 100 can be perpendicular to the axis directions of each other respectively, thereby ensuring the transportation stability of the splicing plate 1.

[0038] Example 2: As Figure 2 and Figure 4 shown, threads are provided in the positioning hole 200 of one of the splicing plates 1 to form a threaded positioning hole 201; threads are also provided at the end of the connecting rod 100. Thus, when transporting the splicing plate 1, the splicing plate 1 provided with the threaded positioning hole 201 can be placed at the bottom, and the remaining splicing plates 1 are superposed upward in sequence. Then, after the connecting rod 100 passes through the aligned positioning holes 200 obliquely from top to bottom, it can be threadedly engaged with the threaded positioning hole 201 on the bottommost splicing plate 1, thereby realizing the fastening of the superposed splicing plates 1 and ensuring the transportation stability.

[0039] It should be noted that the above two examples can both meet the requirements of this application, and those skilled in the art can select according to actual needs. For the above Example 1, a threaded positioning hole 201 can also be formed in the bottommost splicing plate 1 to be threadedly engaged with the connecting rod 100.

[0040] It can be understood that to ensure that all components are in a fixed connection state when the packaging box is folded, the number of the remaining connecting rods 100 after the splicing plates 1 are stacked should be the same as the number of the positioning holes 200 on the splicing plates 1 to ensure that all the remaining connecting rods 100 can be inserted into the positioning holes 200.

[0041] In this embodiment, there are various stacking methods for the packaging box during transportation. It can be formed by superposing multiple splicing plates 1 on each other, or it can be folded after connecting multiple splicing plates 1. For the convenience of understanding, the following will be described in detail through two specific examples in combination with the folding method of the splicing plate 1.

[0042] Example 1: AsFigure 3 As shown, the splicing plates 1 are stacked in sequence in the horizontal direction. Among them, 4 threaded positioning holes 201 are provided on the splicing plate 1 at the bottommost layer, and 4 positioning holes 200 are provided on the remaining splicing plates 1. Correspondingly, there are also 4 connecting rods 100. Adjust the position of the splicing plates so that the positioning holes 200 and the threaded positioning holes 201 are in corresponding positions. Insert the 4 connecting rods 100 obliquely into the corresponding positioning holes 200 and perform threaded cooperation with the threaded positioning 201 holes at the bottom to achieve fixation.

[0043] Example 2: As Figure 4 shown, a plurality of splicing plates 1 are spliced to form an L-shaped box body 2, and a plurality of connecting rods 100 are further provided inside the box body 2; the connecting rods 100 divide the box body 2 into a plurality of folding sections 21 and connecting sections 22. The stacking method of the folding sections 21 and the connecting sections 22 is wrapping and folding. The folding sections 21 are stacked on top of each other, the connecting sections 22 are perpendicular to the folding sections 21, and the dimensions increase in sequence along the stacking direction from bottom to top; after the box body 2 is wrapped and folded, it can be placed on another splicing plate 1 having threaded positioning holes 201. Insert the connecting rods 100 for connecting the head and tail of the box body 2 into the box body 2 in the wrapped and folded state and perform fixation through threaded cooperation.

[0044] It can be understood that the above two examples can both meet the requirements of this application. Those skilled in the art can select according to actual needs. However, it should be noted that the splicing edges of the splicing plates 1 in Example 2 are provided with circular chamfers to facilitate the rotation of each folding section 21 and the connecting section 22 through the connecting rods 100.

[0045] It should be known that the splicing method between the splicing plates 1 can be through connection by the connecting rods 100, or some or all of the splicing plates 1 can be spliced by mutual engagement to reduce the usage quantity of the connecting rods 100.

[0046] In this embodiment, as Figure 5 、 Figure 6 、 Figure 7 shown, the splicing plate 1 includes a side plate 11, a cover plate 12 and a bottom plate 13. Among them, the side plates 11 are connected by the connecting rods 100, the side plates 11 and the cover plate 12 are spliced by a placement structure, and the side plates 11 and the bottom plate 13 are spliced by a clamping structure.

[0047] It should be known that, as Figure 5 shown, a plurality of protruding connection blocks 110 are provided on both sides of the side plate 11, and a recessed connection groove 111 is formed between two adjacent connection blocks 110. When a plurality of side plates 11 are spliced, the connection blocks 110 can be embedded into the corresponding connection grooves 111.

[0048] It should also be known that, as Figure 5 andFigure 8 As shown, perforations 300 are provided on the connecting block 110, and the perforations 300 on the same side are arranged in alignment to facilitate the insertion of the connecting rod 100. To ensure the stability of the splicing of the side plate 11, the lowermost perforation 300 is replaced with a threaded hole 301 with threads. When the side plate 11 is spliced through the cooperation of the connecting block 110 and the connecting groove 111, the perforation 300 and the threaded hole 301 are in alignment. At this time, the bottom thread of the connecting rod 100 can be threadedly engaged with the threaded hole 301 to achieve a fixed connection.

[0049] It should be known that the four sides of the plate surface of the cover plate 12 are blocked and an inner cavity is formed in the middle. The length and width of the side plate 11 are not greater than the inner cavity of the cover plate 12, so that when stacking, the side plate 11 can be completely placed inside the cover plate 12.

[0050] It can be understood that when stacking and transporting, the cover plate 12 is in the lowermost position. Therefore, the threaded positioning hole 201 is provided on the cover plate 12.

[0051] In this embodiment, as Figure 5 and Figure 7 shown, rotating shafts 130 are provided at the central positions of the four sides of the bottom plate 13. Support blocks 400 are elastically and rotatably mounted on the rotating shafts 130 through elastic members. Support holes 112 are provided on the plate surface of the side plate 11.

[0052] It should be known that the side plate 11 and the bottom plate 13 are snap-fitted and installed by inserting the support block 400 into the support hole 112. The installation method of the side plate 11 and the bottom plate 13 can be to sequentially insert the support block 400 into the support hole 112 along the circumferential side direction of the bottom plate 13. After the side plate 11 and the bottom plate 13 are spliced, the connecting rod 100 is inserted to fix the splicing structure between the multiple side plates 11; it can also be to first use the connecting rod 100 to fixedly connect the multiple side plates 11. During this process, the support block 400 is tilted and the elastic member is compressed under the extrusion of the side plate 11. Until the position of the support block 400 corresponds to the support hole 112 and passes through, the support block 400 can be snap-fitted with the support hole 112 under the restoring elastic force of the elastic member. The specific structure and working principle of the elastic member are well-known technologies to those skilled in the art, so they will not be elaborated in detail here; common elastic members include elastic sheets and torsion springs, etc.

[0053] In this embodiment, the shape of the support block 400 is "L" shaped. When the bottom plate 13 is connected to the side plate 11 through the support block 400, the protruding part of the support block 400 is snap-fitted on the outer wall of the side plate 1 to improve the connection stability between the side plate 11 and the bottom plate 13.

[0054] The basic principles, main features and advantages of the present application have been described above. Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, various changes and improvements will occur to the present application, and these changes and improvements all fall within the scope of the present application claimed.
