Description

Technical Field

[0001] The present invention relates to the field of packaging cartons, and more particularly to a non-squeezing stacking packaging carton. Background Art

[0002] As a widely used packaging material, packaging cartons not only play an important role in logistics and transportation, but are also crucial in commodity sales and protection. Among them, squeeze-free packaging cartons improve the protection of the contents through special design or material selection, and reduce the damage caused by external force squeezing during transportation and handling;

[0003] Some fruits need to be packed in cartons during transportation to reduce the damage rate of fruits during transportation. For example, Chinese patent No. CN112320100B discloses an anti-squeezing carton, which can make the partitions in the carton fit closely with the fruits themselves to avoid shaking during transportation. At the same time, it can strengthen the strength of the partitions, improve the anti-squeezing function of the overall structure of the carton, and isolate individual rotten fruits to avoid affecting other fruits in the carton, thereby effectively improving the practicality of the carton.

[0004] Existing packaging cartons store fruits separately by partitions, so as to provide a certain protection for the fruits inside. However, in the actual transportation of fruits, in order to improve the transportation efficiency of fruits, the packaging cartons containing fruits are usually stacked. During the stacking process of fruits such as mangoes, watermelons, and pitayas, the packaging cartons at the bottom will be under great pressure due to their heavy weight. Existing packaging cartons are easily deformed by force during the stacking process. The squeezing deformation of the packaging cartons will not only damage the fruits inside, but also the packaging cartons on the upper side will easily fall over after the deformation of the packaging cartons at the bottom, thereby causing more damage to the fruits. Therefore, there are certain risks and hidden dangers in the actual use of existing packaging cartons. Summary of the invention

[0037] The movable part includes a fixing rod 26 fixedly connected to the top plate 17, the outer surface of the fixing rod 26 is fixedly connected to a mounting seat 27, the mounting seat 27 is a U-shaped structure, the inner surface of the mounting seat 27 is fixedly connected to a pin shaft 28, the outer surface of the pin shaft 28 is rotatably connected to a pull rod 29, the upper end of the pull rod 29 is rotatably connected to a pin shaft 2 30, and the pin shaft 2 30 is fixedly connected to a reinforcing plate 31.

[0038] The pull rod 29, the pin shaft 1 28, and the pin shaft 2 30 are all in two groups and are symmetrically distributed up and down. A folding groove 25 is provided on the outer surface of the top plate 17 away from the fixing rod 26. The reinforcing plate 31 is in an L-shaped structure. A guide strip 32 is slidably connected to the outer surface of the reinforcing plate 31. The guide strip 32 is fixedly connected to the inner surface of the box body 14. A foldable box cover is provided on the upper side of the outer surface of the box body 14.

[0039] By adopting the above technical solution, fruits are usually packaged in cartons to protect their integrity and freshness during transportation due to their unique characteristics and transportation requirements. During transportation, cartons are usually stacked to improve transportation efficiency. At this time, the packaging cartons on the lower side will be subjected to greater extrusion force. In order to improve the compression resistance of the cartons, a supporting component is set. When the packaging carton is used, the lower partition 16 is first placed at the bottom of the box body 14, and then the fruits are placed in the honeycomb holes on the surface of the partition 16. The partition 16 is used to block and protect the fruits, thereby reducing the pressure during transportation. The probability of collision between fruits during the process is reduced, and then the pallet 19 is placed on the upper side of the lower partition 16, and the pallet 19 is supported by the lower partition 16, and then another set of partitions 16 is placed on the upper side of the pallet 19, and the fruits are placed inside the partition 16 again, and the box body 14 cooperates with the partition 16 to package and store the fruits. After the fruits are placed, the box cover is turned over to cover the upper side of the partition 16, and the packaging carton is packaged and stored. Then, the fruits are stacked in sequence, and the top plate 17 is diagonally distributed on the inner side of the box body 14, and the lower box body 14 supports the upper box body 14 through the top plate 17;

[0040] The box body 14 needs to be stacked during transportation. At this time, the lower box body 14 will be affected by the gravity of the upper box body 14 and the fruits. When the lower box body 14 is subjected to excessive pressure, the box body 14 will be squeezed and deformed downward under the pressure. At this time, the top plate 17 will support the upper box body 14. When the lower pressure exceeds the upper limit of the supporting capacity of the top plate 17, the top plate 17 will be folded at the folding groove 25 to the side opposite to the folding groove 25. At this time, as the top plate 17 is gradually folded, the top plate 17 will bring The fixing rod 26 on its surface moves toward the corner of the box body 14. The fixing rod 26 will drive the mounting seat 27 to move synchronously during the movement. The mounting seat 27 is supported by the pull rod 29 through the pin shaft 1 28. The pull rod 29 is hinged with the reinforcing plate 31 through the pin shaft 2 30. As the mounting seat 27 gradually moves, the angle between the pull rod 29 and the top plate 17 will gradually decrease. At this time, the mounting seat 27 pushes the two sets of reinforcing plates 31 through the pull rod 29, and the guide strips 32 on the inner wall of the box body 14 can The reinforcing plate 31 can be slidably guided so that the reinforcing plate 31 can slide smoothly between the two sets of guide strips 32. The reinforcing plate 31 is in an L-shaped structure and can support the corners of the box body 14. The upper reinforcing plate 31 will slide upward under the push of the pull rod 29, and the upper box body 14 can be lifted and supported by the reinforcing plate 31. The upward thrust can offset the extrusion force on the box body 14, thereby reducing the pressure on the lower box body 14 to a certain extent, thereby effectively improving the box body 14. 4 has a compression resistance effect, which reduces the probability of deformation and damage of the box body 14 during the stacking process, thereby ensuring the integrity and yield rate of the fruits inside the box body 14. When the partition 16 is deformed under pressure, the partition 16 will contact the top plate 17 and push the top plate 17 to slide along the inside of the box body 14. The guide groove 37 guides the top plate 17 to slide through the guide block 38, so that the top plate 17 can slide linearly, so that the top plate 17 can push the reinforcing plate 31 again through the movable part.

[0041] like Figure 4 and Figure 7 As shown, a lifting assembly is provided on the outside of the reinforcing plate 31, and the lifting assembly includes a slide plate 18 fixedly connected between two adjacent groups of reinforcing plates 31, and the slide plate 18 is slidably connected to the inner surface of the box body 14. The slide plate 18 passes through the outside of the guide bar 32 and is slidably connected to the guide groove 37, and the outer surface of the lower end of the slide plate 18 is fixedly connected to a connecting plate 21.

[0042] A slot 22 is provided on the lower side of the outer surface of the connecting plate 21, and a traction plate 23 is slidably connected to the inner side of the slot 22. Placement grooves 24 are provided on the left and right ends of the outer surface of the support plate 19 respectively. The traction plates 23 are in two groups and are distributed corresponding to the placement grooves 24. The traction plates 23 are located inside the placement grooves 24.

[0043] By adopting the above technical solution, in order to further improve the compression resistance of the packaging carton and reduce the probability of deformation during the stacking of the packaging carton, a lifting component is set. When the box body 14 is squeezed, as the reinforcing plate 31 moves upward, the reinforcing plate 31 will drive the slide plate 18 to slide upward synchronously, and the slide plate 18 will drive the connecting plate 21 to slide synchronously along the inner wall of the box body 14. The slide plate 18 can improve the anti-deformation effect of the left and right ends of the box body 14 to a certain extent. After the connecting plate 21 moves a certain distance, the lower end of the notch 22 on the surface of the connecting plate 21 will contact the outer surface of the lower end of the traction plate 23, and the traction plate 23 is driven to move upward through the connecting plate 21. The traction plate 23 is placed on the groove 24 The pallet 19 is lifted and supported. During the rising process, the traction plate 23 will drive the pallet 19 to move upward synchronously through the placement groove 24. The pallet 19 drives the partition 16 to contact the box cover on the upper side of the box body 14 to lift and support the box cover, so that the pallet 19 cooperates with the partition 16 to share the extrusion force on the box cover, thereby reducing the risk of damage to the fruit inside the box body 14 due to deformation of the box cover during the stacking of the box body 14. At the same time, by moving the pallet 19 upward, the extrusion pressure of the pallet 19 on the lower partition 16 can be reduced, thereby further reducing the probability of damage to the lower fruit, and further improving the structural strength of the packaging carton, and improving the protective effect of the packaging carton on the fruit.

[0044] like Figure 1 and Fig. 9 As shown, a buffer assembly is arranged on the outside of the box body 14, and the buffer assembly includes a groove 15 opened on the outer surface of the box body 14, and a bracket 13 is slidably connected to the outer surface of the box body 14, and a support seat 11 is fixedly connected to the outer surface of the lower end of the bracket 13, and the upper end of the support seat 11 is open, and a transport groove 12 is opened on the outer surface of the front end of the support seat 11, and a support rod 33 is fixedly connected to the upper end of the inner surface of the groove 15, and a slide groove 35 is opened on the inner side of the support rod 33.

[0045] A second support rod 34 is fixedly connected to the outer surface of the upper end of the support seat 11, and the upper side of the outer surface of the second support rod 34 is located inside the slide groove 35 and is in sliding contact with the slide groove 35. A buffer block 36 is fixedly connected to the upper end of the second support rod 34, and the outer surface of the upper end of the buffer block 36 is fixedly connected to the upper end of the inner surface of the slide groove 35. The buffer block 36 is made of elastic material. The number of the first support rod 33 and the second support rod 34 is several groups and is symmetrically distributed on the front and rear sides of the box body 14.

[0046] By adopting the above technical solution, the support seat 11 lifts and supports the bracket 13, and the transportation groove 12 opened on the surface of the support seat 11 can facilitate the transportation of the packaging carton. The bracket 13 is covered on the lower side of the outer surface of the box body 14, which can not only effectively improve the bearing capacity of the box body 14, but also enable the bracket 13 to protect the side of the box body 14, thereby reducing the risk of deformation and damage of the box body 14 in all directions. The groove 15 opened on the surface of the box body 14 can effectively improve the supporting effect of the side of the box body 14, and the support rod 1 33 set on the inner surface of the groove 15 can further improve the structural strength of the box body 14 in the vertical direction. The support rod 1 33 and the support rod 2 34 are distributed in parallel, which can improve the box body 14. As for the compression resistance, the bracket 13 supports the buffer block 36 through the support rod 2 34. When the box body 14 is deformed by force, the box body 14 drives the support rod 1 33 to move downward through the groove 15. The support rod 2 34 is located inside the slide groove 35 of the support rod 1 33. When the box body 14 is stacked, when the support rod 1 33 moves downward, the buffer block 36 will be squeezed through the slide groove 35. The box body 14 and the buffer block 36 will both undergo a certain degree of elastic deformation. Under the support of the support rod 1 33, the support rod 2 34 and the buffer block 36, the deformation of the box body 14 can be maintained within an appropriate range, thereby reducing the probability of excessive deformation of the box body 14 and ensuring the stability of the box body 14 during the stacking process.

[0047] like Figure 2 and Figure 3 As shown, a limiting assembly is provided inside the box body 14, and the limiting assembly includes a limiting plate 39 fixedly connected to the inner surface of the box body 14, and an elastic plate 40 is slidably connected between adjacent limiting plates 39, and the elastic plate 40 is in an arc shape, and the elastic plate 40 contacts the inner surface of the partition 16.

[0048] By adopting the above technical scheme, the box body 14 guides the elastic plate 40 for sliding through the limit plate 39, and the outer surface of the elastic plate 40 is in contact with the partition 16. The elastic force of the elastic plate 40 can clamp and position the partition 16, which can reduce the probability of movement of the internal partition 16 of the box body 14 during transportation, thereby reducing the risk of rolling of the fruit inside the box body 14. At the same time, when the front and rear sides of the outer surface of the box body 14 collide and squeeze, the arc-shaped elastic plate 40 will produce a certain elastic deformation. At this time, the two ends of the elastic plate 40 will move to both sides on the inner side of the limit plate 39. The elastic force of the elastic plate 40 can effectively buffer and absorb the collision impact force on the surface of the box body 14, which can not only provide a good protection effect on the fruit inside the box body 14, but also reduce the probability of deformation of the side of the box body 14.

[0049] like Figure 4 , Figure 5 and Figure 7As shown, there are four groups of top plates 17 and they are respectively located at the corners of the box body 14 . The upper ends of the top plates 17 are at the same level as the outer surfaces of the upper ends of the partitions 16 . The partitions 16 are honeycomb-shaped, and the front and rear sides of the outer surfaces of the partitions 16 are in contact with the inner surface of the box body 14 .

[0050] Air holes 20 are provided at both left and right ends of the outer surface of the box body 14 , and the front and rear ends of the outer surface of the box body 14 protrude to the inner side of the box body 14 through grooves 15 . The box body 14 and the bracket 13 are both made of corrugated cardboard.

[0051] By adopting the above technical scheme, the upper end of the top plate 17 and the upper end of the partition 16 are at the same height, so that the pressure on the partition 16 can be effectively shared by the top plate 17. The honeycomb shape of the partition 16 can not only increase the loading capacity of the fruit, but also keep the structure of the partition 16 stable. The front and rear sides of the partition 16 are in contact with the inner wall of the box 14, thereby indirectly improving the structural stability of the box 14. The air holes 20 on the surface of the box 14 can realize the circulation of gas inside and outside the box 14, thereby ensuring the normal respiration of the fruit inside the box 14, thereby reducing the risk of fruit rot and deterioration during transportation of the box 14. The box 14 and the bracket 13 are both made of corrugated cardboard, which can make the box 14 and the bracket 13 maintain a certain hardness, thereby improving the stacking capacity of the box 14.

[0052] Instructions for use: When the packaging carton is in use, the fruits are placed in the honeycomb holes on the surface of the partition 16, and the partition 16 is used to block and protect the fruits. The box body 14 cooperates with the partition 16 to package and store the fruits. After the fruits are placed, the box cover is flipped over to cover the upper side of the partition 16. The box body 14 needs to be stacked during transportation. The box body 14 will be squeezed and deformed downward under the action of pressure. At this time, the top plate 17 will support the upper box body 14, and the top plate 17 will be folded at the folding groove 25 to the side opposite to the folding groove 25. The upper reinforcing plate 31 will slide upward under the push of the pull rod 29, and the upper box body 14 is lifted and supported by the reinforcing plate 31. The reinforcing plate 31 will drive the slide plate 18 to slide upward synchronously, and the slide plate 18 drives the traction plate 23 to move upward through the connecting plate 21 The traction plate 23 lifts and supports the support plate 19 through the placement groove 24. During the rising process, the traction plate 23 will drive the support plate 19 to move up synchronously through the placement groove 24. The support plate 19 cooperates with the partition plate 16 to share the extrusion force on the box cover, thereby reducing the risk of damage to the fruit inside the box body 14 due to deformation of the box cover during stacking of the box body 14. The support rod 33 arranged on the inner surface of the groove 15 can further improve the structural strength of the box body 14 in the vertical direction, so that the deformation of the box body 14 can be maintained within an appropriate range. The elastic force of the elastic plate 40 can clamp and position the partition plate 16. The elastic force of the elastic plate 40 can effectively buffer and absorb the collision impact force on the surface of the box body 14, thereby having a good protective effect on the fruit inside the box body 14.

[0053] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
