[0029] The bottoms of both ends of the left side frame 3 and the right side frame 4 are respectively fixedly connected with symmetrically arranged first rotating pins 7. The left side frame 3 and the right side frame 4 are rotatably connected with the two base columns 2 on the corresponding sides through the first rotating pins 7. The base column 2 is provided with a first vertical waist-shaped groove 8 that rotatably cooperates with the first rotating pin 7. The height of the first vertical waist-shaped groove 8 is ≥ the sum of the thicknesses of the left side frame 3 and the right side frame 4.

[0030] A protruding first ear 9 is provided on the top of the base column 2, and side frame columns 16 are connected to both sides of the left frame 3 and the right frame 4. A groove 10 with an opening at the lower end for accommodating the first ear 9 is provided on the outer side wall of the bottom end of the side frame column 16, and a cylindrical locking block 11 that cooperates with the ear hole of the first ear 9 is provided at the bottom of the groove 10 to prevent the left frame 3 and the right frame 4 from flipping outwards.

[0031] The two sides of the bottom ends of the front side frame 5 and the rear side frame 6 are respectively fixedly connected with symmetrically arranged second rotating pins 12, and the opposite side of the base column 2 is provided with a second vertical waist-shaped groove 13 that rotates with the second rotating pin 12. The height of the second vertical waist-shaped groove 13 is ≥ the sum of the thicknesses of the front side frame 5 and the rear side frame 6. The second vertical waist-shaped groove 13 is located below the first vertical waist-shaped groove 8, so that the left side frame 3, the right side frame 4, the front side frame 5, and the rear side frame 6 can be stacked when they are in a folded state.

[0032] In this embodiment, the front side frame 5, the rear side frame 6, the left side frame 3, and the right side frame 4 all adopt a frame structure formed by welding aluminum profiles. The tops of the side frame columns 16 of the left side frame 3 and the right side frame 4 are fixedly provided with second lifting ears 31, and the bottoms of the base columns 2 are all openings that are positioned and plugged into the corresponding second lifting ears 31, so that the stacked turnover box structure is more stable.

[0033] As a further improvement of the present embodiment, in order to facilitate the disassembly and assembly of the front side frame 5 and the rear side frame 6, the outer side wall of the base column 2 is provided with an introduction groove 14 which is respectively connected with the corresponding second vertical waist-shaped groove 13 and forms an L-shaped structure, so that the second rotating pins 12 on both sides of the bottom end of the front side frame 5 and the rear side frame 6 can enter between the second vertical waist-shaped grooves 13 along the introduction groove 14 or separate from the base column 2 along the second vertical waist-shaped groove 13 and the introduction groove 14.

[0034] Spring latches 15 are provided on both sides of the upper parts of the front side frame 5 and the rear side frame 6 , and latch holes for locking and plugging with the spring latches 15 are provided on the side frame columns 16 on both sides of the left side frame 3 and the right side frame 4 .

[0035] The rectangular base 1 is a frame-shaped structure with an opening at the lower end. The four corners of the rectangular base 1 are connected to walking caster assemblies 18. The walking caster assembly 18 includes two wheel seats 19 fixedly connected to the rectangular base 1 and arranged at intervals. The wheel seats 19 are fixed with caster fixing sleeves 20 that penetrate the corresponding wheel seats 19 and are coaxially arranged. A caster shaft 21 with a hollow cavity is rotatably installed between the caster fixing sleeves 20. A caster shaft 21 is fixed with a caster 22 that is rotatably installed through the caster seat 22. The caster 23 slides between the wheel seat 19 and passes through the caster shaft core 24, which coaxially passes through the caster shaft 21 at the same time. The outer end of the caster shaft core 24 passes through the caster fixing sleeve 20 located on the outer side and is connected to a hand wheel 25. By rotating the hand wheel 25, the caster 23 is rotated to a vertical downward supporting state and to a horizontal state. When the caster 23 is rotated to the supporting state, the rectangular base 1 is protruded, and when the caster 23 is rotated to the horizontal state, the rectangular base 1 is not protruded.

[0036] The outer ends of the two caster fixing sleeves 20 are provided with locking grooves 26 for positioning the caster 23 when it is rotated to the supporting state and the horizontal state. The locking grooves 26 of the caster 23 in the supporting state are arranged longitudinally, and the locking grooves 26 in the horizontal state are arranged transversely, and they are staggered by 90°.

[0037] A locking buckle 27 that locks or separates with the corresponding locking groove 26 along the axial direction is fixed respectively between the outer caster fixing sleeve 20 and the handwheel 25 and on the caster shaft core 24 between the inner end of the caster shaft 21 and the inner wheel seat 23. A locking groove 28 corresponding to the position of the locking buckle 27 is provided at the inner end of the caster shaft 21. A reset spring 29 for resetting the caster shaft core 24 inward is also provided between the caster shaft 21 and the caster shaft core 24. An opening 30 corresponding to the position of the handwheel 25 is provided on the side wall of the rectangular bottom 1 to facilitate the operation of the handwheel 25.

[0038] like Figure 8 As shown, when the utility model is folded, the spring latch 15 of the front side frame 5 is first separated from the latch holes 17 of the left side frame 3 and the right side frame 4, and supported inwardly and horizontally on the rectangular base 1, and then the spring latch 15 of the rear side frame 6 is separated from the latch holes 17 of the left side frame 3 and the right side frame 4, and supported inwardly and horizontally on the front side frame 5. Because the second rotating pins 12 on both sides of the bottom ends of the front side frame 5 and the rear side frame 6 are rotatably matched with the base column 2 through the second vertical waist groove 13, the front side frame 5 and the rear side frame 6 can be rotated and folded, and the folding height can also be adjusted.

[0039] Then fold the left side frame 3 and the right side frame 4 inward respectively, so that the left side frame 3 and the right side frame 4 are supported on the front side frame 5 and the rear side frame 6 in turn. Similarly, because the first rotating pins 7 on both sides of the bottom ends of the left side frame 3 and the right side frame 4 are rotatably matched with the base column 2 through the first vertical waist groove 8, the left side frame 3 and the right side frame 4 can be rotated and folded, and the folding height can also be adjusted, thereby realizing the stacking arrangement of the left side frame 3, the right side frame 4, the front side frame 5 and the rear side frame 6.

[0040] When the utility model needs to be promoted, the locking buckle 27 is pulled out of the corresponding locking groove 26 by the hand wheel 25, and at the same time, the locking buckle 27 between the inner end of the caster shaft 21 and the inner wheel seat 23 is driven to be inserted into the locking groove 28 of the caster shaft 21. The hand wheel 25 is rotated to drive the caster shaft 21 and the caster 23 to rotate to the supporting state, and then the hand wheel 25 is released to drive the locking buckle 27 to be inserted into the longitudinally arranged locking groove 26; when the caster needs to be folded during transportation, the locking buckle 27 is driven to be inserted into the transversely arranged locking groove 26. The principle is the same and will not be repeated here. Example 2

[0041] like Fig. 9 As shown, the structure of this embodiment is basically the same as that of embodiment 1, except that the inner walls of the front side frame 5, the rear side frame 6, the left side frame 3, and the right side frame 4 are all connected with a sealing plate 32, the turnover box is covered with a box cover 31 to form a closed box body, and the second lifting ear 30 protrudes upward from the box cover 33.
