Description

Technical Field

[0001] This utility model relates to the field of warehousing and logistics technology, specifically to a riveted turnover box bottom plate assembly. Background Technology

[0002] Turnover boxes are mainly used for the warehousing and logistics of loose parts. They are simple in structure, easy to use, stack neatly, and easy to manage, and are widely used in industries such as machinery, automobiles, home appliances, light industry, and electronics. Currently, turnover boxes on the market are mainly divided into two types: plastic and steel. Due to their processing methods, both types of turnover boxes are mostly non-detachable whole boxes, with the base assembly usually being a welded structure. The welding process easily generates a lot of heat, causing deformation of local structures in the turnover box, affecting molding accuracy, and requiring time-consuming reshaping. Furthermore, welding results in non-detachable connections, making it difficult to disassemble and replace damaged structural components. Utility Model Content

The first vertical rib 19 has a protrusion extending to the left. The second vertical rib 20 is vertically arranged and has a recessed portion extending to the left in the middle. The upper end of the second vertical rib 20 is connected to the right end of the first upper base plate 17, and the lower end is connected to the first lower base plate 18. In two adjacent sets of first base plate profiles 15, the protrusion of the first vertical rib 19 of the right first base plate profile 15 is inserted into the recess of the second vertical rib 20 of the left first base plate profile 15. The riveting of the first base plate profile 15 to the frame 13 is specifically achieved by the rivets passing sequentially through the left part of the first upper base plate 17 of the first base plate profile 15 on the right side, the first vertical rib 19 of the first base plate profile 15, the right part of the first lower base plate 18 of the first base plate profile 15 on the left side, and the frame 13, thus riveting two adjacent sets of first base plate profiles 15 to the frame 13. This arrangement not only achieves riveting with the frame 13 but also further enhances the connection stability between two adjacent sets of first base plate profiles 15. Simultaneously, the first lower base plate protruding to the right of the second vertical rib helps in the positioning and rapid installation of the next set of base plate profiles.

[0057] As a supplement to the above technical solution, the first vertical rib 19 includes a first vertical part 21, a horizontal part 22, a second vertical part 23, and an arc-shaped part 24.
