Description

Technical Field

[0001] This utility model relates to the field of folding case technology, and in particular to a frame structure for a lightweight, high-strength folding case. Background Technology

[0002] A folding box is a type of box that can be folded and stored using a special structure. When unfolded, it can be used as a container for carrying items. It is suitable for various scenarios such as warehousing, logistics, and home use. It is usually made of materials such as plastic, metal, and fabric, and has the characteristics of high strength, good toughness, and easy cleaning. When folded, its volume is greatly reduced, saving space.

[0003] The lightweight, high-strength folding case's frame structure is made of high-strength lightweight alloys and carbon fiber composite materials, combined with modular, foldable rod-shaped or plate-shaped components. Based on hinge, snap-fit, and nesting connection methods, when unfolded, the components lock together to form a stable mechanical structure that can bear heavy loads; when folded, the components can be stacked or folded together by unlocking the connection points to reduce the volume.

[0004] In existing technologies, some folding boxes have problems with the inconvenience of top-loading operations during the storage and retrieval of materials. Operators often need to manually remove the materials placed in the box one by one. When there are many materials piled up in the box or the weight is large, the operation is not only cumbersome and inefficient, but also causes operators to be injured by carrying heavy objects. Frequent manual operation can easily cause damage to the materials. Therefore, a lightweight and high-strength folding box frame structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lightweight, high-strength folding box frame structure, aiming to improve the problem of material damage caused by frequent manual operation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lightweight, high-strength folding case frame structure includes a carrier. The carrier has multiple top grooves inside, with a placement tray slidably connected inside each top groove. A connecting platform is fixedly connected to the bottom of the placement tray. Multiple linkage rods are rotatably connected to the outside of the connecting platform. Multiple linkage columns are rotatably connected to the bottom inner wall of each top groove. Each linkage column has a linkage groove inside, and a spring is fixedly connected to the bottom inner wall of the linkage groove. Two vertical plates are rotatably connected to the top of the carrier, with multiple rubber pads fixedly connected to the bottom of each vertical plate. Horizontal plates are rotatably connected to the front and rear sides of the carrier, and two portable components are opened inside each horizontal plate.

[0008] As a further description of the above technical solution:

[0009] The portable component includes a fixing slot, one of which has a spring two fixedly connected to the left inner wall, a wedge-shaped post fixedly connected to the right side of the spring two, a lever fixedly connected to the front side of the wedge-shaped post, and a partition block fixedly connected to the top of the vertical plate. The partition block has two limiting holes inside.

[0010] As a further description of the above technical solution:

[0011] Multiple T-shaped grooves are respectively opened inside the carrier and inside the vertical plate, and T-shaped blocks are rotatably connected to the left and right sides of the horizontal plate.

[0012] As a further description of the above technical solution:

[0013] The bottom of the linkage rod is fixedly connected to the top of the spring, and the outside of the linkage rod is slidably connected to the inside of the linkage groove.

[0014] As a further description of the above technical solution:

[0015] The bottom of the rubber pad is in contact with the top of the placement tray, and the outside of the T-slot is in contact with the inner wall of the T-block;

[0016] As a further description of the above technical solution:

[0017] The outer side of the wedge-shaped post is slidably connected to the inside of the fixing groove, and the outer side of the wedge-shaped post is in contact with the inner wall of the limiting hole;

[0018] As a further description of the above technical solution:

[0019] The bottom of the horizontal plate and the top of the vertical plate are in contact, and the adjacent sides of the two horizontal plates are in contact with the front and rear sides of the two partition blocks.

[0020] As a further description of the above technical solution:

[0021] The bottom of the vertical plate is in contact with the top of the carrier, and the outside of the fixing groove is formed inside the horizontal plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the rubber pad at the bottom of the vertical plate squeezes the placement tray. After the placement tray is subjected to force, it drives multiple linkage rods through the connecting platform. The linkage rods then receive the force from the connecting platform and squeeze the spring. When the folding box has been turned over, the rubber pad releases the pressure on the placement tray. The linkage rods then drive the connecting platform to lift the placement tray. This achieves compact storage by using the rubber pad to squeeze the placement tray and drive the linkage structure to compress the spring. The spring elastically returns to its original position and automatically lifts the placement tray and materials, making it easy for operators to pick up.

[0024] 2. In this utility model, by rotating the vertical plate, and then rotating the horizontal plate to close it up, the wedge-shaped column is squeezed by the edge of the dividing block, which in turn squeezes the second spring. When it moves to the limiting hole, the wedge-shaped column is inserted into the limiting hole, thus limiting the horizontal plate. Then, the T-shaped block is inserted into the T-shaped groove inside the carrier, thus completing the limiting and fixing of the horizontal plate to the vertical plate. This achieves the T-shaped block and T-shaped groove working together to limit and fix the horizontal plate to the vertical plate. The operation is simple and the fixation is reliable. Moving the lever can easily release the wedge-shaped column from the limiting position. After rotating the horizontal and vertical plates, the T-shaped block and T-shaped groove work together again to fix the horizontal plate, making it convenient and quick to open the folding box.

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a lightweight, high-strength folding box frame structure, including a carrier 1. The carrier 1 provides installation space and support for the upper device. Multiple top grooves 2 are provided inside the carrier 1, providing installation space for the internal material-lifting component. A placement tray 3 is slidably connected inside the top groove 2 for placing materials. A connecting platform 4 is fixedly connected to the bottom of the placement tray 3. The connecting platform 4 receives force from the placement tray 3, thereby driving the linkage rod 5 to move synchronously. Multiple linkage rods 5 are rotatably connected to the outside of the connecting platform 4. The linkage rods 5 receive force from the connecting platform 4 to compress the spring 8. Multiple linkage columns 6 are rotatably connected to the bottom inner wall of the top groove 2. The linkage columns 6 provide space for the opening of the linkage groove 7. The linkage groove 7 is provided inside the linkage column 6, providing fixation and support for the spring 8.

[0033] A spring 8 is fixedly connected to the bottom inner wall of the linkage groove 7. The spring 8 has an elastic function and provides elastic support for its linkage rod 5. Two vertical plates 9 are rotatably connected to the top of the carrier 1. The vertical plates 9 provide fixation and support for the rubber pads 10. Multiple rubber pads 10 are fixedly connected to the bottom of the vertical plates 9. When the vertical plates 9 are closed, the rubber pads 10 are used to protect the material and squeeze the placement tray 3. Then, the connecting platform 4 drives the linkage rod 5 to squeeze the spring 8. After the folding box is completed and the vertical plates 9 are opened, the rubber pads 10 release the pressure on the placement tray 3 and can then be reset by the elastic function of the spring 8. Then, the linkage rod 5 drives the connecting platform 4 to lift the placement tray 3, thereby completing the lifting of the material, which is easier for the operator to lift the material. Horizontal plates 11 are rotatably connected to the front and rear sides of the carrier 1. The horizontal plates 11 are used to cover the vertical plates 9. Two portable components are opened inside the horizontal plates 11.

[0034] Reference Figure 2 and Figure 4The portable component includes a fixing groove 12, which provides fixation and support for the second spring 13. The second spring 13 is fixedly connected to the inner left wall of one of the fixing grooves 12. The second spring 13 has an elastic function, providing elastic support for the wedge-shaped post 14. The wedge-shaped post 14 is fixedly connected to the right side of the second spring 13. When the horizontal plate 11 is closed, the wedge-shaped post 14 is pressed by the edge of the partition block 16, which in turn presses the second spring 13. Then, when it moves to the limiting hole 17, the elastic reset of the second spring 13 causes the wedge-shaped post 14 to engage inside the limiting hole 17, thereby... The horizontal plate 11 is positioned to limit the movement of the horizontal plate 11. A lever 15 is fixedly connected to the front of the wedge post 14. When the folding box needs to be opened, the lever 15 is moved first, which then causes the wedge post 14 to press against the spring 13, disengaging it from the inside of the limiting hole 17. This allows the horizontal plate 11 to rotate, and then the vertical plate 9 to rotate, thus opening the folding box. A partition block 16 is fixedly connected to the top of the vertical plate 9. The partition block 16 is used to separate the two horizontal plates 11 and provide space for the limiting holes 17. Two limiting holes 17 are opened inside the partition block 16. The limiting holes 17 are used to cooperate with the wedge post 14 to fix the horizontal plate 11.

[0035] Reference Figures 2 to 4 Multiple T-slots 18 are provided inside the carrier 1 and the vertical plate 9 respectively. When the folding box is opened, the T-blocks 19 are inserted into the T-slots 18 of the vertical plate 9, thereby fixing the horizontal plate 11 and the vertical plate 9. T-blocks 19 are rotatably connected to the left and right sides of the horizontal plate 11 respectively. The T-blocks 19 are used to cooperate with the T-slots 18. When the folding box is closed, the T-blocks 19 are inserted into the T-slots 18 inside the carrier 1, thereby fixing the horizontal plate 11 to the vertical plate 9. The bottom of the linkage rod 5 is fixedly connected to the top of the spring 8. The spring 8 provides elastic support for the linkage rod 5. The outside of the linkage rod 5 is slidably connected to the inside of the linkage groove 7. The linkage groove 7 provides the linkage rod 5 with the function of limiting and guiding. The bottom of the rubber pad 10 is in contact with the top of the placement tray 3. The rubber pad 10 is used to protect the material and squeeze the placement tray 3.

[0036] The outer side of the T-slot 18 contacts the inner wall of the T-block 19. Similarly, when the folding box is opened, the T-block 19 is inserted into the T-slot 18 of the vertical plate 9, thereby fixing the horizontal plate 11 and the vertical plate 9. When the folding box is closed, the T-block 19 is inserted into the T-slot 18 inside the carrier 1, thereby fixing the horizontal plate 11 to the vertical plate 9. The outer side of the wedge-shaped column 14 is slidably connected to the inside of the fixing groove 12. The fixing groove 12 provides the function of limiting and guiding the wedge-shaped column 14. The outer side of the wedge-shaped column 14 contacts the inner wall of the limiting hole 17. The wedge-shaped column 14 is inserted into the inner wall of the limiting hole 17 to fix the horizontal plate 11. The bottom of the horizontal plate 11 contacts the top of the vertical plate 9. Finally, the horizontal plate 11 is folded to limit the vertical plate 9.

[0037] The two horizontal plates 11 are in contact with each other on one side and the front and rear sides of the two partition blocks 16. The partition blocks 16 limit the horizontal plates 11 on both sides. The bottom of the vertical plate 9 is in contact with the top of the carrier 1. The vertical plate 9 is folded first and then the rubber pad 10 is squeezed against the placement tray 3. The outside of the fixing groove 12 is opened inside the horizontal plate 11. The horizontal plate 11 provides space for the fixing groove 12.

[0038] Working principle: When the folding box is folded, the rubber pad 10 at the bottom of the vertical plate 9 presses the placement tray 3. The placement tray 3, under pressure, drives multiple linkage rods 5 through the connecting platform 4. The linkage rods 5 then receive force from the connecting platform 4 and press the spring 8. When the folding box has finished turning over, the operator opens the vertical plate 9, the rubber pad 10 releases the pressure on the placement tray 3, and the spring 8 returns to its original position due to its elasticity. The linkage rods 5 drive the connecting platform 4 to lift the placement tray 3, thus lifting the material for easy access by the operator.

[0039] When the folding box needs to be folded, the vertical plate 9 is rotated, followed by the horizontal plate 11, to close it up. Then, the wedge-shaped post 14 is pressed by the edge of the partition block 16, which in turn presses the second spring 13. When it moves to the limiting hole 17, the second spring 13 elastically resets it, causing the wedge-shaped post 14 to engage inside the limiting hole 17, thus limiting the horizontal plate 11. Then, the T-shaped block 19 engages inside the T-shaped groove 18 inside the carrier 1, thus completing the limiting and fixing of the horizontal plate 11 to the vertical plate 9. When the folding box needs to be opened, the toggle block 15 is moved first, causing the wedge-shaped post 14 to press against the second spring 13, disengaging it from the limiting hole 17. Then, the horizontal plate 11 and the vertical plate 9 are rotated, and the T-shaped block 19 engages inside the T-shaped groove 18 of the vertical plate 9, thus fixing the horizontal plate 11 and the vertical plate 9 and completing the opening operation of the folding box.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
