[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] Please see Figures 1 to 7 This utility model provides a foldable and assembled PP calcium plastic turnover box, including a base 1 and a side frame 2; The base support 1 includes a base frame 11 and multiple movable rods 12. The four corners of the base support are fixedly provided with clamping plates 15. The multiple movable rods 12 are elastically installed in multiple movable cavities 111 fixedly opened on the base frame 11 by springs 13. The fixed rods 121 fixedly provided at their upper ends move through the movable cavities 111 and extend to the outside of the base frame 11. The side frame 2 is assembled from two long side plates 21 and two wide side plates 22. Each of the long side plates 21 and wide side plates 22 is provided with a sleeve 23 and a strip 24 at its left and right ends, respectively. The sleeve 23 has a groove 231 that engages with the strip 24, corresponding to the shape of the strip 24. The lower end of the sleeve 23 is also fixedly provided with a base 232. The base 232 has a slot 233 that engages with the plate 15, corresponding to the shape of the plate 15. The bottom of the side frame 2 is also provided with a fixing groove 25 that engages with the fixing rod 121, corresponding to the shape of the fixing rod 121.

[0019] In practical application, the side frame 2, which is formed by the engagement of the long side plate 21 and the wide side plate 22, is used to flatten the bottom support 1. The side frame 2 is then aligned with the edge of the bottom support 1 and pressed down vertically. As the side frame 2 is pressed down, the fixing groove 25 squeezes the fixing rod 121, which in turn squeezes the spring 13 through the movable rod 12. When the side frame 2 is pressed down to the locking position, the fixing rod 121 springs back under the elastic potential energy of the spring 13, thus engaging the fixing rod 121 with the fixing groove 25. At the same time, the locking plate 15 also engages with the locking slot 233 under the pressure of the side frame 2, thereby completing the engagement of the bottom support 1 and the side frame 2 and realizing the assembly of the turnover box.

[0020] This embodiment achieves quick and stable assembly through the interlocking structure of the long side plate 21 and the wide side plate 22, in conjunction with the movable rod 12 and the spring 13. Assembly or folding and disassembly can be completed manually and quickly without tools, making operation simple. The combined action of the set clamping plate 15 and the fixing rod 121 ensures the structural stability of the box during use, making it less likely to fall apart or shift when stacked, thus ensuring the safety of the goods.

[0021] Please see Figure 1 , Figure 2 and Figure 4 As another preferred embodiment of the present invention, it also includes two lifting gloves 3, which are made of elastic material and are movably locked in the lifting handle grooves 26 opened on the sides of the two wide side plates 22.

[0022] In practical applications, this embodiment facilitates gripping during handling by using the handle groove 26, and further improves gripping comfort by combining it with the handle glove 3.

[0023] Please see Figure 3 As another preferred embodiment of the present invention, a positioning strip 151 is also fixedly provided on the card plate 15, and a positioning groove 234 that engages with the positioning strip 151 is fixedly provided in the card slot 233 at the position corresponding to the positioning strip 151.

[0024] In practical applications, the positioning strip 151 engages with the positioning groove 234, which can serve as a positioning function during use and can also improve structural stability in the event of slippage and disintegration of the turnover box under load.

[0025] Please see Figure 3 , Figure 4 and Figure 7 In another preferred embodiment of the present invention, a convex bottom 16 is fixedly provided at the lower end of the bottom frame 11, and the shape of the convex bottom 16 is adapted to the shape of the top opening of the side frame 2.

[0026] Furthermore, a plurality of locking blocks 161 are fixedly provided on the outer side of the convex bottom 16, and a plurality of locking slots 27 corresponding to the locking blocks 161 are fixedly provided on the upper end of the side frame 2.

[0027] In practical applications, this embodiment adapts the convex bottom 16 to the side frame 2, facilitating the stacking of turnover boxes and improving the stability of stacking. Furthermore, the combination of the set card block 161 and card slot 27 further enhances the structural stability by engaging during stacking.

[0028] Please see Figure 5 In another preferred embodiment of the present invention, a spring groove 112 is fixedly provided at one end of the movable cavity 111, a limit rod 122 is fixedly provided at one end of the movable rod 12, one end of the spring 13 is movably fitted into the spring groove 112, and the other end of the spring 13 is movably fitted onto the limit rod 122.

[0029] In practical applications, the spring groove 112 and the limiting rod 122 in this embodiment play a role in positioning and limiting the spring 13. When the spring 13 is compressed, the stability of the force on the spring 13 can be ensured, thereby improving the flexibility of the fixed rod 121 to move under the compression of the spring 13, and thus ensuring the engagement stability of the fixed rod 121 and the fixed groove 25.

[0030] Please see Figures 3 to 5 In another preferred embodiment of the present invention, the base support 1 further includes an adjusting member 14 for adjusting the position of the movable rod 12. The adjusting member 14 includes a movable block 141 and a lever 142. The movable block 141 is slidably engaged with the movable groove 123 fixedly opened on the side of the movable rod 12. The lever 142 is fixedly installed on the side of the movable block 141. An adjusting groove 113 is fixedly opened on the side of the movable cavity 111 at the position corresponding to the lever 142. The adjusting groove 113 is set as an "L" shaped groove. The lever 142 moves through the adjusting groove 113 and extends to the outside of the bottom frame 11.

[0031] In practical application, when the turnover box needs to be disassembled, the lever 142 is manually moved along the adjustment groove 113, and the movable rod 12 is moved by the engagement of the movable block 141 with the movable groove 123. Based on the "L"-shaped structure of the adjustment groove 113, the lever 142 is locked in the vertical section of the adjustment groove 113, thereby releasing the engagement of the fixed rod 121 with the fixed groove 25. Then, the locking plate 15 is separated from the locking slot 233 to complete the disassembly of the turnover box. When it is necessary to assemble, the lever 142 is moved to the horizontal section of the adjustment groove 113, and the locking function with the fixed groove 25 is restored under the action of the spring force 13.
