[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 The utility model provides a technical solution: it includes a bottom plate 3, a hinge 4 connected to one side of the bottom plate 3, a side plate 2 connected to the top of the bottom plate 3 through the hinge 4, and a top plate 1 connected to the top of the side plate 2. There are multiple hinges 4. A first rectangular groove 6 is opened on the top of the top plate 1. A slider 11 is slidably connected to the middle part of the first rectangular groove 6. The top of the slider 11 is fixedly connected to the limiting block 12. A second rectangular groove 14 is opened at the bottom of the bottom plate 3. A clamping block 16 is slidably connected to the middle part of the second rectangular groove 14. A clamping groove 18 is opened in the clamping block 16. The top of the limiting block 12 is slidably inserted in the clamping groove 18. A buffer assembly is provided in the first rectangular groove 6. The other end of the buffer assembly is connected to the slider 11 for buffering the movement of the slider 11.

[0023] During specific implementation, the goods are placed on the top of the bottom plate 3, and then the staff uses multiple sets of hinges 4 to splice multiple side panels 2 and the bottom plate 3 into a cubic packaging box, and fix the top plate 1 and the side panels 2 through fixing bolts 5. When multiple packaging boxes are transported, the packaging boxes need to be stacked together, and the four corners of the bottom plate 3 of the upper packaging box and the top plate 1 of the lower packaging box are aligned, so that the second rectangular groove 14 is parallel to the first rectangular groove 6, and the clamping groove 18 opened in the clamping block 16 is aligned with the limit block 12 fixedly connected to the top of the slider 11. When the limit block 12 is clamped with the clamping groove 18, the limitation of the packaging boxes to be stacked is completed.

[0024] For further information, see Figure 2 The buffer assembly includes two fixed plates 7, which are respectively fixedly mounted on the two side walls of the first rectangular groove 6. A damping cylinder 9 and a buffer spring 10 are fixedly connected between one of the fixed plates 7 and the slider 11, and the buffer spring 10 is sleeved on the damping cylinder 9.

[0025] During specific implementation, a buffer assembly is provided to buffer the movement of the slider 11. When transporting multiple stacked boxes, in order to avoid tipping over after being subjected to inertia, the clamping block 16 at the bottom of the bottom plate 3 of the upper box moves in the direction opposite to the transportation direction. At this time, the second magnet 17 is magnetically connected to the first magnet 13, driving the limit block 12 clamped in the clamping block 16 to move, driving the slider 11 to move horizontally along the guide rod 8. One end of the buffer spring 10 fixedly connected to the top plate 1 through the fixed plate 7 is connected to the slider 11. When the slider 11 moves, it exerts a force on the damping cylinder 9, and the damping cylinder 9 will produce elastic deformation to absorb the impact force. The buffer spring 10 will produce a damping force to gradually eliminate the vibration, thereby producing a buffering effect on the slider 11.

[0026] For further information, see Figure 2 The top of the limiting block 12 is fixedly connected to the first magnet 13 , and the interior of the clamping groove 18 is fixedly connected to the second magnet 17 . The first magnet 13 and the second magnet 17 are magnetically connected.

[0027] In a specific implementation, the first magnet 13 and the second magnet 17 are magnetically connected to improve the stability of the limiting block 12 being clamped in the clamping block 16 .

[0028] For further information, see Figure 2 and Figure 3 A guide rod 8 is fixedly installed between the two fixed plates 7, and the slider 11 is movably sleeved on the guide rod 8. A telescopic rod 15 is fixedly connected to one side of the clamping block 16, and one end of the telescopic rod 15 is fixedly connected to the inner wall of the second rectangular groove 14.

[0029] In specific implementation, by setting the guide rod 8, the slider 11 can move horizontally along the guide rod 8 in the first rectangular groove 6, and by setting the telescopic rod 15, the clamping block 16 can move in the second rectangular groove 14 in the extending and retracting direction of the telescopic rod 15.

[0030] For further information, see Figure 1 The inner diameter of the clamping groove 18 is slightly larger than the outer diameter of the limiting block 12, and the limiting block 12 is provided with an integrally formed anti-slip pattern.

[0031] In specific implementation, by setting the inner diameter of the snap-fit groove 18 to be slightly larger than the outer diameter of the limit block 12, the limit block 12 and the snap-fit groove 18 are smoothly snapped together, and by providing an integrally formed anti-slip pattern on the limit block 12, the stability of the limit block 12 snapped into the snap-fit block 16 through the snap-fit groove 18 is improved.

[0032] For further information, see Figure 1 The top plate 1 and the bottom plate 3 have the same outer diameter, the center of the first rectangular groove 6 coincides with the diagonal center of the top plate 1 , and the center of the second rectangular groove 14 coincides with the diagonal center of the bottom plate 3 .

[0033] In specific implementation, the stability of stacking of packaging boxes is improved by providing the top plate 1 and the bottom plate 3 with the same outer diameter, and the centers of the first rectangular groove 6 and the second rectangular groove 14 are made to coincide, thereby improving the convenience of clamping when stacking the packaging boxes.

[0034] For further information, see Figure 1 The top of the top plate 1 is threaded with fixing bolts 5 around the periphery, and the side plate 2 is fixedly connected to the top plate 1 through the fixing bolts 5. The number of the fixing bolts 5 is four.

[0035] During specific implementation, after the goods are placed between multiple side panels 2 on the top of the bottom panel 3, the packaging box is sealed using the top panel 1, and the top panel 1 is fixed to the multiple side panels 2 by setting threaded fixing bolts 5. The top panel 1 and the side panels 2 are fixedly connected by the fixing bolts 5, which ensures the stability of the packaging box after assembly, ensures that the goods can be fully protected during transportation, and improves the convenience of opening the packaging box and taking out the goods during unloading.

[0036] For further information, see Figure 1 One side of the fixing plate 7 is threadedly connected with bolts, and the bolts are located at the four corners of the fixing plate 7. There are four bolts, and the fixing plate 7 is fixedly connected to the top plate 1 by the bolts.

[0037] In specific implementation, two fixing plates 7 are provided and fixedly connected to the top plate 1 by bolts. When the buffer assembly is damaged, the connection between the fixing plates 7 and the top plate 1 can be released by rotating the bolts, and the entire assembly can be taken out for repair or replacement, thereby improving the convenience of disassembling the buffer assembly.

[0038] Working principle: When in use, the staff first places the goods on the top of the bottom plate 3, and then the staff uses multiple sets of hinges 4 to splice multiple side panels 2 and the bottom plate 3 into a cube-shaped packaging box, and finally fixes the top plate 1 and the side panels 2 through fixing bolts 5 to ensure the stability of the packaging box after assembly. When multiple packaging boxes are transported, the packaging boxes need to be stacked together, and the four corners of the bottom plate 3 of the upper packaging box and the top plate 1 of the lower packaging box are aligned, so that the second rectangular groove 14 is parallel to the first rectangular groove 6, and the telescopic rod 15 is located on the side opposite to the fixed plate 7. The clamping groove 18 opened in the clamping block 16 is aligned with the limit block 12 fixedly connected to the top of the slider 11. When the limit block 12 is clamped with the clamping groove 18, the limit of the packaging boxes to be stacked is completed.

[0039] When transporting multiple stacked packaging boxes, in order to avoid tipping over after being subjected to inertia, the clamping block 16 at the bottom of the bottom plate 3 of the upper packaging box moves in the direction opposite to the transportation direction. At this time, the second magnet 17 and the first magnet 13 are attracted to each other under the action of magnetism, driving the limit block 12 clamped in the clamping block 16 to move, driving the slider 11 to move horizontally along the guide rod 8. One end of the buffer spring 10 fixedly connected to the top plate 1 through the fixed plate 7 is connected to the slider 11. When the slider 11 moves, it generates a force on the damping cylinder 9, and the damping cylinder 9 will produce elastic deformation to absorb the impact force. The buffer spring 10 will generate a damping force to gradually eliminate the vibration, allowing the slider 11 to reset, buffering the clamping block 16, and preventing the stacked packaging boxes from tipping over due to inertia.
