Description

Technical Field

[0001] This application relates to the field of pallet box technology, specifically a reinforcing rib structure for the bottom support of a high load-bearing pallet box. Background Technology

[0002] A palletized box is a packaging container consisting of a pallet (base), a box body, and a lid. It is constructed by stacking the pallets and using one or more side panels. It is mainly used in logistics and warehousing, and plays an important role, especially in the manufacturing, food, chemical, electronics, and retail industries.

[0003] Currently, some high-load-bearing pallet boxes use reinforcing ribs to support and lift the cargo at the bottom. These reinforcing ribs are generally fixed, with a fixed and uniform spacing between each rib. This fixed spacing of the reinforcing ribs cannot be adjusted according to the actual weight distribution of the cargo. When the weight distribution of the cargo is uneven, the fixed spacing of the reinforcing ribs may cause some areas to bear too much weight, while other areas may not bear enough weight, thus affecting the overall load-bearing capacity and stability of the pallet box. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art by proposing a reinforcing rib structure for a high load-bearing panel box bottom support, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a reinforcing rib structure for the bottom support of a high load-bearing panel box, including a bottom support frame. The bottom of the bottom support frame is fixedly connected to a support leg. Several fixing reinforcing ribs are fixedly connected to the inner side of the bottom support frame. A sliding groove is opened on one side of the bottom support frame. A sliding plate is slidably connected in the sliding groove. Several displacement reinforcing ribs are fixedly connected to the side of the sliding plate near the fixing reinforcing ribs. A driving mechanism for changing the position of the displacement reinforcing ribs is provided on the bottom support frame.

[0006] Preferably, the driving mechanism includes a fixed shaft fixedly connected to the outer surface of the base bracket, an electric actuator rotatably connected to the outer surface of the fixed shaft, and a recessed frame fixedly connected to the output end of the electric actuator. The driving mechanism can move the displacement reinforcing rib on the slide plate, thereby causing it to be misaligned with the fixed reinforcing rib to different degrees to meet different load-bearing requirements.

[0007] Preferably, a curved spring is provided on the base bracket, the top of the curved spring is fixedly connected to the bottom of the recessed frame, and a frame shaft is fixedly passed through the inner side of the recessed frame.

[0008] Preferably, a connecting piece is rotatably connected to the outer surface of the frame shaft, a fixed platform is fixedly connected to the outer surface of the base bracket, and a rotating shaft is rotatably connected to the inner surface of the fixed platform.

[0009] Preferably, a drive plate is fixedly connected to one end of the rotating shaft near the connecting piece, and a guide shaft is fixedly connected to the outer surface of the connecting piece, with the outer surface of the guide shaft rotatably connected to the end of the drive plate away from the rotating shaft.

[0010] Preferably, a gear is fixedly connected to the end of the rotating shaft away from the drive plate, and a rack is fixedly connected to the bottom of the slide plate, with the outer surface of the rack meshing with the outer surface of the gear.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The reinforcing rib structure of the bottom support of this high load-bearing pallet box allows for adjustment of the position of the reinforcing ribs by allowing them to shift. The spacing between the reinforcing ribs can be flexibly adjusted according to the actual weight distribution of the goods. In this way, areas with heavier loads can receive more support, while areas with lighter loads can receive less support, thereby optimizing the load-bearing distribution of the entire pallet box. This optimization can significantly improve the overall load-bearing capacity of the pallet box and avoid structural damage or deformation caused by excessive local load.

[0013] 2. The reinforced rib structure of this high load-bearing panel box bottom support, with adjustable rib spacing, can better adapt to the weight distribution of the goods, providing more stable support and helping to reduce the shaking and collision of goods during transportation, thereby reducing the risk of damage to the goods. At the same time, the adjustable rib spacing provides greater flexibility, allowing the position of the goods to be temporarily adjusted according to the actual situation.

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Please see Figure 1-4 A reinforcing rib structure for a high load-bearing capacity pallet box base includes a base bracket 1, with a support leg 2 fixedly connected to the bottom of the base bracket 1. Several fixed reinforcing ribs 3 are fixedly connected to the inner side of the base bracket 1. A sliding groove 4 is provided on one side of the base bracket 1, and a sliding plate 5 is slidably connected in the sliding groove 4. Several displacement reinforcing ribs 6 are fixedly connected to the side of the sliding plate 5 near the fixed reinforcing ribs 3. The diameter of the displacement reinforcing ribs 6 is smaller than the diameter of the fixed reinforcing ribs 3. This is to ensure that the highest positions of the two are basically on the same plane, so that they can work together to assist in bearing the load of the goods. During the lateral movement of the displacement reinforcing ribs 6, the distance between them and the fixed reinforcing ribs 3 will change. A drive mechanism for changing the position of the displacement reinforcing ribs 6 is provided on the base bracket 1.

[0021] Through the above technical solution, the bottom support 1 at the bottom of the enclosure box is supported and bears the weight of the goods by the cooperation of the fixed reinforcing rib 3 and the displacement reinforcing rib 6. When it is necessary to adjust the position of the reinforcing rib according to the actual weight distribution of the goods, the position of the displacement reinforcing rib 6 can be adjusted laterally by the drive mechanism, so that it is gradually misaligned with the fixed reinforcing rib 3 until it is misaligned to a suitable degree.

[0022] Specifically, the drive mechanism includes a fixed shaft 7 fixedly connected to the outer surface of the base bracket 1, an electric actuator 8 rotatably connected to the outer surface of the fixed shaft 7, and a recess 9 fixedly connected to the output end of the electric actuator 8.

[0023] Through the above technical solution, the design of the fixed shaft 7 is to adapt to the positional changes of the electric actuator 8 itself, because the electric actuator 8 will have a certain angular deflection during the process of pushing and pulling the concave frame 9.

[0024] Specifically, a curved spring 10 is provided on the bottom bracket 1, the top of the curved spring 10 is fixedly connected to the bottom of the recessed frame 9, and a frame shaft 11 is fixedly inserted through the inner side of the recessed frame 9.

[0025] Through the above technical solution, during the process of pushing the connecting piece 12 through the frame shaft 11 to deflect it, the connecting piece 12 will deflect accordingly, and the guide shaft 16 will move synchronously during this period. The curved spring 10 mainly plays the role of providing auxiliary flexible support for the recessed frame 9.

[0026] Specifically, a connecting piece 12 is rotatably connected to the outer surface of the frame shaft 11, a fixed platform 13 is fixedly connected to the outer surface of the base bracket 1, and a rotating shaft 14 is rotatably connected to the inner surface of the fixed platform 13.

[0027] Through the above technical solution, during the deflection process, the connecting piece 12 will drive the driving piece 15 through the guide shaft 16, so that the driving piece 15 drives the rotating shaft 14 to rotate during the swing process.

[0028] Specifically, a drive plate 15 is fixedly connected to one end of the rotating shaft 14 near the connecting plate 12, and a guide shaft 16 is fixedly connected to the outer surface of the connecting plate 12. The outer surface of the guide shaft 16 is rotatably connected to the end of the drive plate 15 away from the rotating shaft 14.

[0029] Through the above technical solution, as the drive plate 15 drives the rotating shaft 14 to swing (make a certain degree of circular motion), the rotating shaft 14 will rotate accordingly, and then the linkage gear 17 will rotate synchronously.

[0030] Specifically, a gear 17 is fixedly connected to the end of the rotating shaft 14 away from the drive plate 15, and a rack 18 is fixedly connected to the bottom of the slide plate 5. The outer surface of the rack 18 meshes with the outer surface of the gear 17.

[0031] Through the above technical solution, the gear 17 will drive the rack 18 that meshes with it during its rotation, thereby causing the slide plate 5 to slide laterally in the slide groove 4, that is, all the displacement reinforcing ribs 6 move laterally in sync (gradually displaced from the fixed reinforcing ribs 3).

[0032] Working Principle: During the support of goods, the bottom support frame 1 of the pallet box utilizes the fixed reinforcing ribs 3 and the shifting reinforcing ribs 6 to bear the load. To adapt to the actual weight distribution of the goods on the bottom support frame 1 and reduce the situation where some reinforcing ribs are overloaded due to uneven weight distribution, while other areas are underloaded, thus improving the overall load-bearing capacity and stability of the pallet box, the position of the reinforcing ribs can be adjusted as needed (here, the position of the shifting reinforcing rib 6 is adjusted). When adjusting the position of the shifting reinforcing rib 6, the recessed frame 9 can be pushed and pulled using the electric actuator 8. During this process, the electric actuator 8 will deflect at a certain angle along the fixed axis 7. The recessed frame 9 and the electric actuator 8 are subjected to auxiliary flexible support from the curved spring 10 during this deflection. This allows the recessed frame 9 to drive the connecting piece 12 via the frame shaft 11. The process is more stable. When the concave frame 9 drives the connecting piece 12 through the frame shaft 11, it will cause the connecting piece 12 to deflect. The connecting piece 12 will push and pull the driving piece 15 through the guide shaft 16, causing the driving piece 15 to swing at a certain angle. During this period, the rotating shaft 14 at the end of the driving piece 15 will rotate synchronously with the rotation of the driving piece 15. As a result, the gear 17 will rotate synchronously. During the rotation of the gear 17, it will drive the rack 18 to make the slide plate 5 slide laterally along the slide groove 4. During the lateral movement of the slide plate 5, all the displacement reinforcing ribs 6 will move laterally synchronously. That is, the displacement reinforcing ribs 6 and the fixed reinforcing ribs 3 will gradually be misaligned (the distance between the two will change) until the fixed reinforcing ribs 3 and the displacement reinforcing ribs 6 are adjusted to a suitable distance to adapt to the corresponding load distribution requirements.

[0033] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
