Description

Technical Field

[0001] The utility model belongs to the technical field of logistics transportation equipment, in particular to a logistics box for logistics transportation. Background Art

[0002] Logistics boxes, also known as turnover boxes, are widely used in machinery, automobiles, home appliances, light industry, electronics and other industries. They are acid-resistant, alkali-resistant, oil-resistant, non-toxic and odorless. They can be used to hold food, etc. They are easy to clean, and parts turnover is convenient, neatly stacked, and easy to manage. Its reasonable design and excellent quality are suitable for transportation, distribution, storage, circulation and processing in factory logistics. The turnover box can be used in conjunction with a variety of logistics containers and workstation equipment, and can be used in various warehouses, production sites and other occasions. Today, when logistics management is increasingly valued by the majority of enterprises, turnover boxes help complete the universal and integrated management of logistics containers, and are essential for production and distribution companies to carry out modern logistics management.

[0003] Existing logistics boxes are usually just a simple box structure, and the goods need to be stacked in the box when storing and transporting goods. For ordinary goods, there is no problem using this stacking method, but it is not very suitable for some fragile goods. In the prior art, fragile goods are often protected by adding foam pads in the middle of the goods. However, this method still requires stacking the goods, and the goods on the bottom layer are still easily damaged, especially for long plate-like goods, such as PCB boards. If stacked, the pins on the PCB are easily damaged. Therefore, the existing logistics boxes have the problem of being difficult to store fragile plate-like goods.

[0004] A logistics box is disclosed in the patent with publication number CN111559576A, in which a side of the box cover close to the bottom plate is detachably fixedly connected with an elastic layer, and a plurality of elastic protrusions are provided on the elastic layer. By driving the power module to move the bottom plate up and down in the box, the volume inside the box can be adjusted. A logistics box of this structure can store different goods according to actual needs by changing the volume of the logistics box. However, this logistics box still uses a stacking method when storing goods, and therefore cannot meet the storage needs of fragile plate-like goods. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example

[0030] A logistics box for logistics transportation, such as Figure 1 As shown, it includes a box frame 1, an upper matching plate 6, a lower matching plate 4 and a screw rod 7; the upper matching plate 6 is connected to the box frame 1 through the screw rod 7, and the lower matching plate 4 is connected to the box frame 1;

[0031] The screw rod 7 is rotatably connected to the box frame 1, and the upper mating plate 6 is threadedly connected to the screw rod 7; the lower mating plate 4 is connected to the bottom of the box frame 1; the screw rod 7 is used to adjust the height position of the upper mating plate 6, and the upper mating plate 6 is moved in the axial direction of the screw rod 7 by rotating the screw rod 7, thereby adjusting the distance between the upper mating plate 6 and the lower mating plate 4, which is convenient for storing plate-like goods of different specifications.

[0032] like Figure 2 As shown, the upper mating plate 6 and the lower mating plate 4 are both provided with a clamping groove 8 on one side close to each other, and the clamping grooves 8 are evenly spaced on the upper mating plate 6 and the lower mating plate 4. The clamping grooves 8 are used to limit the plate-like goods and can easily separate the plate-like goods.

[0033] Specifically, in actual use, the upper mating plate 6 is first driven to move by rotating the screw rod 7, and the distance between the upper mating plate 6 and the lower mating plate 4 is adjusted by moving the upper mating plate 6, and the distance between the upper mating plate 6 and the lower mating plate 4 is reasonably adjusted according to the width of the plate-like goods. After adjusting the distance, the plate-like goods are placed in an upright state and inserted between the upper mating plate 6 and the lower mating plate 4, and both sides of the plate-like goods need to be clamped into the clamping slot 8. In this way, all the plate-like goods are inserted in sequence. Since the plate-like goods are placed upright between the upper mating plate 6 and the lower mating plate 4, the plate-like goods will not be damaged due to stacking. The design of the clamping slot 8 can limit the plate-like goods, avoid squeezing or collision of adjacent plate-like goods, and can effectively protect the plate-like goods. This storage method can store more plate-like goods, and there will be no waste of volume space. For example, when storing a PCB board, the PCB is placed upright and inserted between the upper mating plate 6 and the lower mating plate 4, and the pins on the PCB board will not be squeezed, so that the PCB board is not easily damaged.

[0034] In a preferred embodiment, if Figure 1 As shown, panels 2 are fixedly connected to both sides of the box frame 1. In a further optimized manner, observation windows 3 are provided on the panels 2. The panels 2 on both sides are used to protect the goods in the box frame 1 and prevent the goods in the box frame 1 from being directly hit by the outside. The observation windows 3 are convenient for the staff to observe whether the goods stored in the box frame 1 are damaged. At the same time, it is also convenient to observe whether the posture of the goods is correct when storing the goods.

[0035] In a preferred embodiment, if Figure 1 , Figure 3As shown, a movable connecting frame 5 is provided above the upper matching plate 6 in the box frame 1, and the movable connecting frame 5 is threadedly connected to the screw rod 7, and the upper matching plate 6 is detachably connected to the movable connecting frame 5. Specifically, the upper matching plate 6 is bolted to the movable connecting frame 5. Both sides of the movable connecting frame 5 are threadedly connected to the screw rod 7. When the screw rod 7 is rotated, the screw rod 7 drives the movable connecting frame 5 to move, and the movable connecting frame 5 drives the upper matching plate 6 to move. This designer is for the convenience of replacing the upper matching plate 6. Preferably, the lower matching plate 4 is also detachably connected to the box frame 1. By replacing the upper matching plate 6 and the lower matching plate 4, plate-shaped goods of different specifications can be stored. It should be noted that the widths of the positioning grooves 8 on different upper matching plates 6 and lower matching plates 4 are different, and the upper and lower matching plates with different width positioning grooves 8 can adapt to plates of different thicknesses.

[0036] In a preferred embodiment, if Figure 1 , Figure 4 As shown, four screw rods 7 are arranged on the box frame 1, and the four screw rods 7 are respectively arranged at the four corners of the box frame 1; the bottoms of the four screw rods 7 are fixedly connected with secondary pulleys 12, and the bottom of the box frame 1 is rotatably connected with a main pulley 11, and the main pulley 11 is connected to all the secondary pulleys 12 through a belt 13. The four screw rods 7 are arranged to ensure the stability of the upper matching plate 6 and prevent the upper matching plate 6 from tilting. One main pulley 11 drives four secondary pulleys 12 at the same time to facilitate the simultaneous rotation of the four screw rods 7, ensuring the stable movement of the upper matching plate 6.

[0037] In a preferred embodiment, if Figure 4 As shown, the bottom of the box frame 1 is provided with an adjustment groove 15, and the top of the primary pulley 11 is detachably connected in the adjustment groove 15. The design of the adjustment groove 15 is to facilitate the adjustment of the position of the primary pulley 11. By adjusting the position of the primary pulley 11, the belt 13 can be tightened or loosened, thereby ensuring that the primary pulley 11 can stably drive the secondary pulley 12 to rotate. Preferably, the top of the primary pulley 11 is rotatably connected to a rotating shaft, and a connecting block is provided on the top of the rotating shaft. The connecting block is movably connected in the adjustment groove 15, and the connecting block can move in the adjustment groove. At the same time, the connecting block can also be fixed in position by bolting with the box frame 1. Through this design, the primary pulley 11 can move in the direction of the adjustment groove 15, thereby tightening the belt 13 or loosening the belt 13. When the position of the primary pulley 11 needs to be fixed, it is achieved by bolting the connecting block to the box frame 1.

[0038] In a preferred embodiment, if Figure 4 , Figure 5As shown, a number of positioning grooves 14 are evenly spaced around the main pulley 11, and a limiting telescopic rod 16 is connected to the bottom of the box frame 1 near the main pulley 11; the limiting telescopic rod 16 includes an outer tube 17 and an inner rod 19, and the middle part of the inner rod 19 is movably connected in the outer tube 17; a limiting portion 20 is provided in the middle of the inner rod 19, and a compression spring 21 is provided between the outer tube 17 and the limiting portion 20; a clamping portion 18 is provided at one end of the inner rod 19, and the clamping portion 18 cooperates with the positioning groove 14. In the process of transporting the logistics box, the main pulley 11 at the bottom is easy to contact with the outside world and rotate, so the main pulley 11 needs to be limited. Figure 4 or Figure 5 As shown, the compression spring 21 in the limiting telescopic rod 16 can push the inner rod 19 to move to the left, and the clamping portion 18 on the left side of the inner rod 19 is inserted into the positioning groove 14, thereby preventing the main pulley 11 from rotating. When the main pulley 11 needs to be rotated, the clamping portion 18 is disengaged from the positioning groove 14 by pulling the inner rod 19.

[0039] In a preferred embodiment, if Figure 3 As shown, a support pad 10 is fixedly connected to the bottom of the box frame 1. The support pad 10 is used to elevate the box frame 1 and can protect the main pulley 11 and the limiting telescopic rod 16 located at the bottom of the box.

[0040] In a preferred embodiment, if Figure 2 As shown, guide openings 9 are provided on both sides of the clamping grooves 8 on the upper mating plate 6 and the lower mating plate 4, and the guide openings 9 are structures with openings inclined outwards. The guide openings 9 are arranged in a structure inclined outwards, which can have a certain guiding effect, and can reduce the possibility of collision between the plate goods and the upper mating plate 6 or the lower mating plate 4.

[0041] In a preferred embodiment, the upper mating plate 6 and the lower mating plate 4 are both made of rubber material on one side close to the slot 8. This design is to make the upper mating plate 6 and the lower mating plate 4 on one side close to the slot 8 relatively soft, thereby protecting the plate cargo and preventing the plate cargo from being damaged.
