Description

Technical Field

[0001] This utility model relates to the field of logistics boxes, specifically a logistics box that can be stably stacked. Background Technology

[0002] Logistics boxes primarily serve to protect, transport, and store goods, reducing damage and loss during transportation and ensuring the safety of goods. They can be used with various logistics containers and workstation equipment, and are suitable for various warehouses, production sites, and other occasions. They are essential for modern logistics management in production and distribution enterprises.

[0003] Chinese patent CN216970375U discloses a stackable logistics turnover box, including a box body with handle grooves on both sides and a rubber layer on the inner wall. The upper end of the box body has a docking groove, and the bottom of the box body has a docking strip in the shape of a ring. This stackable logistics turnover box allows the docking strip at the bottom of one box body to be docked with the docking groove at the top of another box body. When the boxes are pressed down, the protrusion on one box body engages with the groove on another box body. The limiting seats at the corners of the boxes body guide and limit the stacked boxes, thus facilitating the stacking of logistics turnover boxes and preventing them from tipping over.

[0004] In the process of connecting the aforementioned patented logistics turnover boxes, the boxes are only connected by the locking mechanism at the groove position. When encountering shaking during transportation, the boxes are prone to separation and it is difficult to lock them together again. There is no additional structural restraint for locking them together. This means that the boxes need to be placed in a stable position when they are connected, which cannot cope with the transportation environment and cannot be stacked stably during transportation. Utility Model Content

[0005] The purpose of this utility model is to provide a logistics box that can be stably stacked. The grab hook inside the upper connecting end is flipped so that the grab hook rotates and embeds into the outside of the support rod inside the upper and lower connecting ends. The rotation of the transmission block outside the threaded rod can fit and fix the flipped grab hook. The grab hook grabs the outside of the support rod and, together with the pressing of the transmission block, can provide additional fixation after the two boxes are locked together, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a logistics box that can be stably stacked, comprising a box body, upper connecting ends provided at the upper ends of both sides of the box body, and a grab hook provided on one side of the outer side of each of the two upper connecting ends, and the grab hook is rotatably connected to the front and rear ends of the upper connecting end through a connecting rod; lower connecting ends provided at the lower ends of both sides of the box body, and a pair of support rods arranged laterally inside the two lower connecting ends; the grab hook is provided with an installation groove inside, and three installation grooves are evenly distributed laterally, the reserved installation grooves facilitate the flipping of the grab hook, and facilitate the grab hook to flip and lock onto the outside of the support rod and threaded rod, which can provide additional connection for two stacked boxes.

[0007] Preferably, a threaded rod is provided between the two support rods, and three mounting slots are respectively connected to the support rod and the threaded rod slot. After the grab hook rotates, the three mounting slots can rotate with the grab hook, allowing the grab hook to rotate into the lower connecting end, so that further connection can be made after the two boxes are engaged.

[0008] Preferably, a transmission block is provided on the outside of the threaded rod, and the inside of the transmission block is threaded with the outside of the threaded rod. After the grab hook rotates, the transmission block rotates and moves along the threaded rod to contact and press the grab hook, which can fix the rotated grab hook and improve the connection between the two boxes.

[0009] Preferably, handles are provided at the middle position on both sides of the box. The reserved handles facilitate carrying and moving of the box, and make it convenient for users to use.

[0010] Preferably, each of the two support rods has a limiting plate at its upper end. The limiting plate is an integral structure with the support rod. The limiting plate connected to the support rod can limit the transmission block and prevent the transmission block from rotating outside the threaded rod and falling off.

[0011] Preferably, a first magnet is fixed to the side of the hook facing the upper connecting end with glue, and a second magnet is fixed to the side of the upper connecting end facing the hook with glue. The second magnet is magnetically connected to the first magnet. The magnetic connection between the second magnet and the first magnet can provide stability for the transmission of the hook and prevent the hook from shaking and loosening when it is not hooked inside the lower connecting end.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When connecting two boxes, this invention allows for engagement by embedding the base into the upper part of the box. Then, the hook inside the upper connecting end can be flipped to rotate and engage with the support rod inside the lower connecting end. Finally, the rotation of the transmission block outside the threaded rod engages and secures the flipped hook. The hook gripping the support rod, combined with the pressing of the transmission block, provides additional fixation after the two boxes are engaged, ensuring stable stacking and preventing loosening of the connection during transport. This design can handle various transport environments. Attached Figure Description

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a logistics box that can be stably stacked in this embodiment includes a box body 1. A base 3 is provided at the lower end of the box body 1, and the outside of the base 3 is connected to the upper end of the box body 1 through a slot. When two boxes 1 are stacked, the two boxes 1 are connected by the base 3 of one box body 1 engaging with the upper end of the other box body 1.

[0022] Furthermore, a tray 2 is arranged around the base 3 and the box 1, and the box 1, the tray 2 and the base 3 are an integral structure. The reserved tray 2 can assist in the support during the locking process. During the locking process, the upper box 1 of the two stacked boxes rests directly on the lower tray 2.

[0023] In order to improve the stability of the two boxes 1 when stacked, upper connecting ends 5 are provided on the upper ends of both sides of the box 1. A hook 12 is provided on one side of the outside of the two upper connecting ends 5. The hook 12 is rotatably connected to the front and rear ends inside the upper connecting ends 5 through the connecting rod 11. The hook 12 can be flipped and stored by rotating. Similarly, the two stacked boxes 1 can be hooked after the hook 12 is rotated.

[0024] In this embodiment, to facilitate the rotation and connection of the grab hook 12, lower connecting ends 4 are provided on the lower ends of both sides of the housing 1. A pair of support rods 7 are laterally arranged inside the two lower connecting ends 4, and a threaded rod 8 is provided between the two support rods 7. Figure 4 and Figure 5 As shown, the hook 12 has an internal mounting groove 13, and three mounting grooves 13 are evenly distributed laterally. The three mounting grooves 13 are respectively connected to the support rod 7 and the threaded rod 8. The three reserved mounting grooves 13 can facilitate the insertion of the support rod 7 and the threaded rod 8. The reserved mounting grooves 13, support rod 7 and threaded rod 8 can facilitate the combination and connection of the two boxes 1, and improve the stability of the stacking of the two boxes 1.

[0025] It is worth mentioning that a transmission block 9 is provided on the outside of the threaded rod 8, and the inside of the transmission block 9 is threaded with the outside of the threaded rod 8. When the transmission block 9 rotates outside the threaded rod 8, it can move longitudinally along the threaded rod 8. After the hook 12 rotates and the threaded rod 8 is embedded in the hook 12, the transmission block 9 can rotate and fit against the hook 12. Fitting against the hook 12 can fix the rotated hook 12, realizing the connection after the two boxes 1 are stacked.

[0026] To facilitate the handling of the box 1, handles 6 are provided in the middle of both sides of the box 1, and the handles 6 are an integral part of the box 1.

[0027] The threaded rod 8 is made of metal, and the housing 1 is made of plastic. Before the housing 1 is injection molded, the threaded rod 8 is placed in a specific cavity of the injection mold. Injection molding is an existing technology, and no additional improvements have been made to the injection method or the injection process in this application. Therefore, the connection method between the threaded rod 8 and the housing 1 is not described in detail in this application.

[0028] The lower connecting end 4, the upper connecting end 5, the support rod 7, and the connecting rod 11 are all integral structures with the box body 1. They are all made of rubber, which facilitates uniform injection molding and makes the processing of logistics boxes easier.

[0029] To prevent the rotating transmission block 9 from falling off, a limiting plate 10 is provided at the upper end of each of the two support rods 7. The limiting plate 10 is an integral structure with the support rod 7. The transmission block 9 can be restricted by the pre-molded limiting plate 10, preventing the transmission block 9 from falling off after rotation.

[0030] To improve the stability of the hook 12, a first magnet 14 is fixed to the side of the hook 12 facing the upper connecting end 5 with glue, and a second magnet 15 is fixed to the inside of the upper connecting end 5 facing the hook 12 with glue. The second magnet 15 is magnetically connected to the first magnet 14. When the hook 12 is not in use, the hook 12 and the upper connecting end 5 are temporarily fixed by the magnetic connection between the second magnet 15 and the first magnet 14.

[0031] Working principle: When stacking logistics boxes, one box 1 is placed at the bottom of the placement position, and the base 3 of the other box 1 faces the groove at the upper end of the box 1. The two boxes 1 can be locked together by the mutual restraint of the two trays 2. Rotating the hook 12 on the side of the lower box 1 causes the hook 12 to rotate around the connecting rod 11 in the corresponding upper connecting end 5. The rotation causes the hook 12 to be embedded in the upper box 1 and into the corresponding lower connecting end 4 of the upper box. The support rod 7 is embedded in the mounting groove 13. Rotating the transmission block 9, the threaded engagement between the transmission block 9 and the threaded rod 8 allows the transmission block 9 to move toward the hook 12 and be close to the hook 12 to fix the position of the hook 12 embedded in the lower connecting end 4. This can fix the connection between the upper and lower boxes 1 and improve the connection between the two boxes 1.
