Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel turnover boxes, and in particular to a foldable stainless steel turnover box. Background Technology

[0002] In modern logistics, warehousing, and industrial production, turnover boxes are widely used as important container equipment in the storage, handling, and transportation of goods. Stainless steel turnover boxes, with their excellent corrosion resistance, high strength, and good hygiene properties, occupy an important position in industries with high requirements for environmental hygiene and material quality, such as food processing, pharmaceutical manufacturing, and electronic component storage.

[0003] However, traditional stainless steel turnover boxes often suffer from low space utilization and inconvenient storage and transportation. On the one hand, traditional stainless steel turnover boxes are mostly fixed structures, large in size and non-foldable, still occupying a lot of storage space when empty, increasing warehousing costs and transportation difficulties. This defect is particularly obvious in enterprises that need a large number of turnover boxes for goods turnover, which not only reduces the space utilization of the warehouse, but also increases the loading difficulty and transportation costs of transport vehicles. On the other hand, with the rapid development of the logistics industry and the intensification of market competition, enterprises have increasingly higher requirements for logistics efficiency and cost control. The fixed structure of traditional stainless steel turnover boxes limits their flexible application in different scenarios and makes it difficult to meet the needs of enterprises for efficient and convenient logistics solutions. Therefore, we propose a foldable stainless steel turnover box. Utility Model Content

[0017] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0018] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown. A foldable stainless steel turnover box includes: a top frame 1, with a plurality of first slots 2 evenly arranged on the lower frame wall of the top frame 1, a sliding rod 3 arranged inside the first slot 2, a hinge seat 4 slidably arranged on the sliding rod 3, a support rod 5 hinged on the hinge seat 4, a bottom frame 7 connected to the bottom end of the support rod 5 via a pivot, a second slot 8 arranged on the bottom frame 7 for use with the support rod 5, a metal guard plate 6 connected to the bottom of the top frame 1 via a hinge, the metal guard plate 6 being rotatably connected in the vertical direction, and the bottom of the metal guard plate 6 being connected via a hinge. The hinge connects to the bottom frame 7. When the stainless steel turnover box needs to be folded, the worker presses the top frame 1 downwards. At this time, because the metal guard plate 6 is connected to the top frame 1 and the bottom frame 7 through the hinge, and the metal guard plate 6 is rotatably connected in the vertical direction, the metal guard plate 6 can be folded inwards. At the same time, because the support rod 5 is slidably connected to the slide rod 3 through the hinge seat 4, and its bottom is rotatably connected to the bottom frame 7 through the mounting shaft 9, the top frame 1 can be moved downwards, thereby completing the folding of the front and rear side walls of the stainless steel turnover box.

[0019] The top frame 1 also has a cavity 10 inside, in which a sliding plate 11 is slidably mounted. The sliding plate 11 is equipped with a rod 12. The hinge seat 4 is equipped with a socket for use with the rod 12. When the stainless steel turnover box needs to be unfolded, the worker pulls the top frame 1 upward to unfold the metal protective plate 6. At the same time, the support rod 5 moves to the support position under the action of the hinge seat 4, thereby supporting the top frame 1. After the support rod 5 moves to the support position, the rod 12 is inserted into the socket, thereby fixing the hinge seat 4, thus ensuring the support quality of the support rod 5, and thus ensuring the efficiency of the use of the metal protective plate 6.

[0020] A return spring 14 is sleeved on the outside of the support rod 13. One end of the return spring 14 is connected to the inner wall of the cavity 10, and the other end of the return spring 14 is connected to the slide plate 11. Under the action of the return spring 14, the connection quality between the insertion rod 12 and the insertion hole is ensured, thereby ensuring the efficiency of the support rod 5. A pull plate 15 is provided at the bottom end of the support rod 13. The support rod 13 can be moved by the pull plate 15, thereby allowing the insertion rod 12 to be moved out of the insertion hole.

[0021] On the inner walls of the left and right sides of the top frame 1, there are rotating winding rollers 16, and protective curtains 17 are installed on the winding rollers 16. The other end of the protective curtains 17 is fixedly connected to the bottom frame 7. At this time, under the action of the winding rollers 16, the protective curtains 17 can be wound up, which also facilitates the folding of the stainless steel turnover box.

[0022] In actual use, when the stainless steel turnover box needs to be used, the worker first pulls the top frame 1 upwards. At this time, since the metal protective plate 6 is connected to the top frame 1 and the bottom frame 7 through hinges, and the metal protective plates 6 in the vertical direction are connected to each other by rotation, as the top frame 1 rises, the metal protective plate 6 will gradually unfold to form the side wall of the turnover box. At the same time, under the action of the hinge seat 4, the support rod 5 slides along the slide rod 3 to the support position. Its bottom is connected to the bottom frame 7 through the pivot, forming a stable support for the top frame 1. After the support rod 5 moves to the support position, the restriction on the slide plate 11 is released by manual operation (such as pulling the pull plate 15) (assuming that the pull plate 15 initially drives the support rod 13 so that the insertion rod 12 is in the retracted state). Under the elastic action of the return spring 14, the slide plate 11 drives the insertion rod 12 to automatically insert into the insertion hole on the hinge seat 4, thereby fixing the position of the hinge seat 4, ensuring the support stability of the support rod 5, and thus ensuring the unfolding and use efficiency of the metal protective plate 6. In addition, protective curtains 17 are pre-installed on the take-up rollers 16, which are rotatably mounted on the inner walls of the left and right sides of the top frame 1. The other end of the protective curtains 17 is fixedly connected to the bottom frame 7. When the top frame 1 rises and the metal protective plate 6 unfolds, the protective curtains 17 gradually unfold with the rotation of the take-up rollers 16, covering the opening of the turnover box and providing protection. It also facilitates the automatic winding of the protective curtains 17 by the take-up rollers 16 when folding the turnover box, without affecting the folding operation.

[0023] When the stainless steel turnover box needs to be folded, the worker moves the support rod 13 by pulling the plate 15, causing the insertion rod 12 to move out of the insertion hole of the hinge seat 4, thus releasing the fixation of the hinge seat 4. Then, the top frame 1 is pressed downwards, and the metal guard plate 6 folds inwards under the action of the hinge. At the same time, the support rod 5 moves as the top frame 1 descends under the sliding connection between the hinge seat 4 and the slide rod 3, until the turnover box is completely folded. During this process, the protective curtain 17 automatically rewinds under the action of the winding roller 16, completing the folding operation.

[0024] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
