Abstract
Description
Technical Field
[0001] This utility model relates to the field of turnover box technology, and more specifically, to a production line turnover box that is easy to stack. Background Technology
[0002] Production line turnover boxes are containers used for storing and transporting materials, widely used in industries such as machinery, automobiles, home appliances, light industry, and electronics. They are typically made of plastic, paper, or steel, and are characterized by acid and alkali resistance, oil resistance, and being non-toxic and odorless, making them suitable for storing food and other items. Turnover boxes are widely used in production lines, primarily for logistics and warehousing. They enable three-dimensional storage of goods in warehouses, and their high load-bearing capacity and stacking performance allow for multi-layer stacking even under heavy loads, increasing warehouse storage space. Current turnover box stacking methods involve placing one turnover box on top of the next, with the raised base at the bottom of the previous turnover box inserting into the inner cavity of the next, thus stacking the two turnover boxes.
[0003] However, the height of the raised base at the bottom of the turnover box is limited, which makes it difficult to ensure the stability of stacking two turnover boxes. When there are some items with a volume smaller than the inner cavity of the turnover box, it is necessary to divide the inner cavity of the turnover box. However, the existing turnover boxes are not convenient to adjust the division area of the inner cavity according to actual needs, which affects the stability of the items placed in the turnover box. Therefore, we propose a production line turnover box that is easy to stack. Utility Model Content

Insert holes 8 are opened at both ends of the multiple upper reinforcing plates 2. A partition mechanism 9 is provided in the inner cavity of the turnover box body 1. A buckle groove 16 is opened on the bottom surface of the lever block 6.
[0028] In this embodiment, when the previous turnover box 1 is placed on the next turnover box 1, the pin 5 at the end of the previous turnover box 1 is inserted into the insertion hole 8 on the upper reinforcing plate 2, thereby strengthening the fixation between the two turnover boxes 1. The turnover box 1 can be made by injection molding.
[0029] For details, please refer to Figure 1 and Figure 5The separating mechanism 9 includes multiple side slots 10 opened on both sides of the inner cavity of the turnover box 1 and multiple end slots 11 opened at both ends of the inner cavity of the turnover box 1. A long insert plate 12 is fitted between two end slots 11 and in the inner cavity of the turnover box 1. A short insert plate 13 is fitted between two side slots 10 and in the inner cavity of the turnover box 1. The top surface of the long insert plate 12 is provided with multiple upper cross grooves 14. The bottom surface of the short insert plate 13 is provided with multiple lower cross grooves 15. The short insert plate 13 is fitted in the inner cavity of one upper cross groove 14, and the bottom end of the long insert plate 12 is fitted in the inner cavity of one lower cross groove 15.
[0030] For details, please refer to Figures 1 to 4 The two ends of the bottom surface of the lever block 6 are fixedly connected to the upper connecting ring 20, and the top surfaces of the two ends of the lower reinforcing plate 3 are fixedly connected to the two lower connecting rings 19. The top and bottom ends of the spring 7 are provided with connecting hooks 21. One connecting hook 21 is sleeved on the outside of the upper connecting ring 20, and the other connecting hook 21 is sleeved on the outside of the lower connecting ring 19.
[0031] In this embodiment, when the connecting hook 21 is fitted onto the upper connecting ring 20 and the lower connecting ring 19, the connecting hook 21 is moved to make it into a circle, and its mating ends are welded so that the spring 7 can be installed between the lower reinforcing plate 3 and the moving block 6.
[0032] For details, please refer to Figure 1 and Figure 2 Multiple vertical ribs 17 are fixedly connected to the outside of the turnover box 1 and between the upper reinforcing plate 2 and the lower reinforcing plate 3.
[0033] In this embodiment, the external strength of the turnover box 1 is enhanced by using vertical rib plates 17.
[0034] For details, please refer to Figures 1 to 3 Multiple perforations 4 and multiple insertion holes 8 are arranged concentrically, and the outer diameter of the pin 5 is equal to the inner diameter of the perforations 4 and the insertion holes 8, respectively.
[0035] In this embodiment, it is ensured that the pin 5 can be smoothly inserted into the inner cavity of the socket 8, while ensuring the stability of the pin 5 inserted into the inner cavity of the through hole 4 and the socket 8.
[0036] For details, please refer to Figure 1 and Figure 5 The position of the upper cross groove 14 is aligned with the position of the side slot 10, the position of the end slot 11 is aligned with the position of the lower cross groove 15, the thickness of the separating mechanism 9 is equal to the width of the inner cavity of the side slot 10 and the upper cross groove 14, and the thickness of the long insert plate 12 is equal to the thickness of the inner cavity of the end slot 11 and the lower cross groove 15.
[0037] In this embodiment, the short insert plate 13 and the long insert plate 12 are smoothly inserted into the inner cavity of the turnover box 1, thereby using the long insert plate 12 and the short insert plate 13 to divide the inner cavity of the turnover box 1 into multiple storage areas.
[0038] For details, please refer to Figure 1 and Figure 2 The bottom surface of the turnover box 1 is provided with a bottom insertion frame 18, and the outer side of the bottom insertion frame 18 is flush with the inner wall of the side slot 10.
[0039] In this embodiment, the bottom insert frame 18 below the previous turnover box 1 can be inserted into the inner cavity of the next turnover box 1, thereby limiting and initially fixing the stacking of the upper and lower turnover boxes 1.
[0040] Working principle: When multiple turnover boxes 1 are stacked, the bottom insert frame 18 of the previous turnover box 1 is inserted into the inner cavity of the next turnover box 1. The contact between the inner wall of the turnover box 1 and the side of the bottom insert frame 18 provides initial positioning between the two turnover boxes 1. In addition, the pin 5 below the lower reinforcing plate 3 is inserted into the insertion hole 8 on the upper reinforcing plate 2, thereby providing further positioning between the two turnover boxes 1 and ensuring the stability between the stacked turnover boxes 1. When it is necessary to remove the turnover box 1, the finger is inserted into the buckle groove 16 to move the lever 6 upward. The lever 6 is used to move the pin 5 out of the inner cavity of the insertion hole 8. When the top surface of the lever 6 is in contact with the bottom surface of the bottom upper reinforcing plate 2, the bottom end of the pin 5 just disengages from the insertion hole 8 on the side of the lower turnover box 1, thereby releasing the positioning between the two turnover boxes 1 so that the upper turnover box 1 can be moved down.
[0041] When it is necessary to divide the inner cavity of the turnover box 1 into four spaces, first insert the long insert plate 12 into the inner cavity of the turnover box 1, so that both ends of the long insert plate 12 are inserted into the inner cavities of the two end slots 11, thereby dividing the width of the inner cavity of the turnover box 1 into two spaces. Then insert the short insert plate 13 into the inner cavity of the turnover box 1, so that both ends of the short insert plate 13 are inserted into the inner cavities of the two side slots 10, and the short insert plate 13 is engaged in the upper cross groove 14 above the long insert plate 12, while the bottom end of the long insert plate 12 is engaged in the inner cavity of the lower cross groove 15, thereby dividing the inner cavity of the turnover box 1 into four storage spaces. At the same time, by adjusting the position of the long insert plate 12 and the short insert plate 13, the inner cavity of the turnover box 1 can be divided into different spaces.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
