Description

Technical Field

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

[0002] Paper packaging is a form of packaging that uses paper and paperboard as the main materials. It uses a folded structure that forms its own space to hold products. It is not only lightweight, but also reduces the packaging cost of the products. Paper box packaging, by using corrugated paper and foam as lining, can reduce the impact, vibration and compression during transportation. It is suitable for packaging and transporting fragile or delicate products. At the same time, compared with metal or wooden boxes, paper boxes are lightweight, which can significantly reduce transportation costs.

[0003] Chinese patent document publication number CN221025121U discloses a multifunctional packaging paper box, including a paper box body, a sliding positioning mechanism, and a support mechanism. The sliding positioning mechanism includes a slide rail, a sliding cover, and a support block. The slide rail is located at the corner of the paper box body. The sliding cover is slidably mounted on the slide rail and extends one end to the upper surface of the paper box body. The support block is located on the lower surface of the paper box body and is equipped with a pulley. The sliding cover has a positioning block facing the upper surface of the paper box body. The support mechanism is located inside the paper box body and connected to the slide rail.

[0004] The aforementioned utility model uses slide rails and connecting pins to slide and support the sliding cover and positioning blocks used for stacking cartons. The stacked cartons are supported by the support blocks and support positioning posts at the four bottom corners. Meanwhile, the entire stacked cartons rely on the bottom cartons as the main load-bearing body. The bottom of the bottom cartons is easily deformed and damaged under pressure. At the same time, the slide rails at the four side corners are subjected to long-term stress during the pushing and transporting of the cartons, which can easily cause damage to the edges of the upper cartons. Therefore, we propose a multifunctional paper packaging box. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a multifunctional paper packaging box, including a paper box, the bottom four corners of which are slidably fitted into a support mechanism, the support mechanism being slidably fitted into the bottom of a stacking mechanism, and the bottom four corners of the stacking mechanism being provided with casters.

[0006] In some embodiments, the support mechanism includes a support plate that is attached to the bottom of the paper box. The support plate has a grid structure, and the four corners of the support plate are rounded. The top of the rounded corner edges of the support plate are provided with limiting frames that fit into the four corners of the bottom of the paper box.

[0007] In some embodiments, the stacking mechanism includes two sets of four corner supports of an I-beam structure and a side bracket connecting the two sets of four corner supports. The four corner supports are provided with support grooves at their top four corners. The support grooves are quarter-circle arc structures, and arc-shaped clips are slidably connected in the support grooves.

[0008] In some embodiments, the arc-shaped clips are fixedly installed on the bottom four corners of the support plate, the support plate is slidably connected between the side brackets through the arc-shaped clips, and the support plate is attached to the four corner supports located below.

[0009] In some embodiments, a limiting slot is provided at the top edge of the side bracket, and a side support corner with a quarter-circle arc structure is slidably connected in the limiting slot. The side support corner is fixed to the bottom four corners of the four-corner support.

[0010] In some embodiments, the paper box is a cardboard box structure composed of an inner first corrugated paper and an outer second corrugated paper. Both the first and second corrugated papers consist of a top plate, a bottom plate, and a corrugated support that serves as a central connection. The corrugated supports in the first corrugated paper and the corrugated supports in the second corrugated paper are distributed perpendicularly to each other.

[0011] This utility model has at least the following beneficial effects:

[0012] 1. In this utility model, the upper and lower limits of the arc-shaped clips and support grooves constitute the connection parts of the four corner supports and the support plate. During the stacking process, the limiting grooves on the side brackets are sleeved on the side support corners and fixed to each other by fixing pins. Each stack of paper boxes is sleeved in the limiting frame on the support plate. The weight of the upper paper boxes is supported by the side brackets in the stacking mechanism, so as to avoid the paper boxes at the bottom being damaged by excessive pressure during the stacking process.

[0013] 2. In this utility model, during the stacking process, the top four corner supports are connected to the top of the side brackets through side support corners. After being fixed, they are connected to the bottom four corner supports to form a square frame support structure. The push slots opened on the four corner supports serve as the force-bearing structure for pushing and pulling, improving the overall user experience during the pushing process. At the same time, during the pushing and pulling process, the force-bearing structure is borne by the side support corners on the four corner supports, which will not generate pressure on the four corners of the cardboard box, thus avoiding damage to the edges of the upper cardboard box during pushing.

[0019] 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.

[0020] Example 1:

[0021] Please see Figure 1-3 This utility model provides a technical solution: a multifunctional paper packaging box, including a paper box 1, the bottom four corners of the paper box 1 are slidably fitted into a support mechanism 2, the support mechanism 2 is slidably fitted into the bottom of a stacking mechanism 3, and the bottom four corners of the stacking mechanism 3 are provided with casters 4. The paper box 1 serves as a packaging holding structure, and its internal space is used to stack products that need to be packaged. The casters 4 are fixed on the bottom stacking mechanism 3 to facilitate the pushing and transferring of products, which together constitute the multiple practical effects of the packaging box.

[0022] After the paper box 1 is assembled, its bottom is fitted into the support mechanism 2. At the same time, the support mechanism 2 is fitted into the bottom of the single-layer stacking mechanism 3, as shown in the attached figure. Figure 3 The paper box 1 is enclosed by a set of closed frames from the outside; after stacking, each set of stacking mechanisms 3 is stacked up and down in sequence, and the entire weight is supported by the outer closed frames.

[0023] Example 2:

[0024] Please see Figure 1-3This utility model proposes a technical solution in which the support mechanism 2 includes a support plate 21 attached to the bottom of the paper box 1. The support plate 21 has a grid structure and rounded corners at its four corners. The top of the rounded corner edges of the support plate 21 is provided with limiting frames 22 that fit around the bottom corners of the paper box 1. The support plate 21 bears the weight of the entire paper box 1. The limiting frames 22 at the four corners fit around the edges of the paper box 1, limiting the position of the paper box 1 and preventing it from tilting or slipping due to inertial forces during transportation, thus ensuring the stability of the product during transportation.

[0025] Example 3:

[0026] Please see Figure 1-3 This utility model proposes a technical solution in which the stacking mechanism 3 includes two sets of four-corner supports 33 with an I-beam structure and a side bracket 36 connecting the two sets of four-corner supports 33. The four corners of the top of the four-corner supports 33 are provided with support grooves 32. The support grooves 32 are quarter-circular arc structures, and arc-shaped clips 31 are slidably connected in the support grooves 32. The arc-shaped clips 31 are fixedly installed on the bottom four corners of the support plate 21. The arc-shaped clips 31 are slidably connected between the side brackets 36 and fixed on the bottom four corners of the support plate 21. After being inserted into the quarter-circular arc structure support grooves 32, the support plate 21 on which the paper box 1 is placed is auxiliaryly limited. The rounded corner structure of the support plate 21 and the support grooves 32 can reduce stress concentration when subjected to force and prevent the support plate 21 from cracking at the four corners when subjected to force.

[0027] The support plate 21 is slidably connected to the side supports 36 via arc-shaped clips 31, and the support plate 21 is attached to the four corner supports 33 located below. A limiting slot 35 is provided on the top edge of the side supports 36, and a quarter-circle arc-shaped side support 34 is slidably connected in the limiting slot 35. The side support 34 is fixed to the bottom four corners of the four corner supports 33. The four corner supports 33 located at the top are interlocked with the arc-shaped side support 34 through the limiting slot 35. When fixation is required, fixing bolts can be used to lock them in place to prevent them from falling off. The arc-shaped structure of the side supports 36 makes the entire enclosed frame more rounded, preventing scratches to workers at the edges, and also allowing for better handling under stress. The force is transmitted to the contact surface of the entire side support corner 34, increasing the force-bearing area and reducing the impact received per unit area, thereby ensuring the overall structural stability. The upper and lower limits of the arc-shaped clip 31 and the support groove 32 form the connection parts of the four corner supports 33 and the support plate 21. During the stacking process, the limiting groove 35 on the side bracket 36 is sleeved on the side support corner 34 and fixed to each other by the fixing pin. Each stack of paper boxes 1 is sleeved in the limiting frame 22 on the support plate 21. The weight of the upper paper box 1 is supported by the side bracket 36 in the stacking mechanism 3, so as to avoid the paper box 1 at the bottom being damaged by excessive pressure during the stacking process.

[0028] Example 4:

[0029] Please see Figure 4 This utility model proposes a technical solution whereby the cardboard box 1 is a cardboard box structure composed of an inner layer of first corrugated paper 101 and an outer layer of second corrugated paper 102. Both the first corrugated paper 101 and the second corrugated paper 102 are composed of a top plate 1001, a bottom plate 1002, and a corrugated support 1003 serving as a central connection, as shown in the attached figure. Figure 4 The wave support 1003 in the first corrugated paper 101 and the wave support 1003 in the second corrugated paper 102 are distributed perpendicularly to each other. Both the first corrugated paper 101 and the second corrugated paper 102 are composed of a top plate 1001, a bottom plate 1002 and a wave support 1003. The wave support 1003 serves as the central buffer structure of the corrugated paper. Its continuous undulation of waves forms an "I-beam" effect, which enhances the lateral rigidity. At the same time, the wave support 1003 in the first corrugated paper 101 and the second corrugated paper 102 are distributed perpendicularly to each other, which can provide enhanced lateral rigidity from both the horizontal and vertical directions, ensuring the load-bearing capacity of the entire paper box 1 after assembly.
