DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figures 1 to 4 The portable eight-wheel detachable steel frame structure provided by the utility model includes a cross bar 1, mounting seats 2 are fixedly provided at both ends of the cross bar 1, three rollers 3 are movably provided in the two mounting seats 2, two vertical rods 4 are fixedly provided on the top of the cross bar 1, and locking structures 5 are fixedly provided on the tops of the two vertical rods 4. The locking structure 5 includes a locking box 501 fixedly installed with the vertical rod 4, a hinge seat 502 is fixedly provided on the inner wall of one side of the locking box 501, a locking frame 503 is movably provided in the hinge seat 502, a spring 504 is fixedly provided on the inner wall of one side of the locking box 501, and a top rod 505 is movably provided on the inner wall of one side of the locking box 501. The setting of the locking structure 5 can realize the locking of the plug block 7 and complete the fixation of the backrest frame 6;

[0027] Reference Figure 2 to Figure 3 In order to separate the backrest frame 6 from the vertical rod 4, the two locking structures 5 are connected with the same backrest frame 6. Two plug blocks 7 are fixedly provided at the bottom of the backrest frame 6. The plug blocks 7 are movably connected to the locking box 501. Limiting grooves are provided on the front inner wall and the back inner wall of the locking box 501. Limiting strips are fixedly provided on the front and back of the plug block 7. The limiting grooves and the limiting strips are adapted to each other. A card block 8 is fixedly provided on one side of the plug block 7. The lock frame 503 includes a locking rod and a lock buckle. The side where the lock buckle and the card block 8 are close to each other is provided with an inclined surface. The inclined surface on one side of the lock buckle is parallel to the inclined surface on one side of the card block 8. The backrest frame 6 can be disassembled by pushing the lock frame 503 to separate it from the card block 8.

[0028] Reference Figure 4In order to separate the load carrier 12 from the vertical rod 4, two connecting seats 9 are fixedly provided on one side of the backrest frame 6, and the same load carrier 12 is clamped on one side of the two connecting seats 9. A card slot 15 is provided on the connecting seat 9. Two connecting blocks 11 are fixedly provided on one side of the load carrier 12. A card plate 10 is fixedly provided on the side of the connecting block 11 close to the connecting seat 9. The card plate 10 and the card slot 15 are adapted. The vertical rod 4, the backrest frame 6 and the load carrier 12 are all made of stainless steel. The load carrier 12 Two universal wheels 13 are fixedly provided at the bottom. The coordinated use of the card plate 10 and the card slot 15 can realize the quick fixation of the cargo rack 12. When disassembling, the card plate 10 is pulled upward to separate it from the card slot 15, and the cargo rack 12 can be removed from the frame, reducing the difficulty of disassembly. Four limit frames 14 are fixedly provided on the top of the cargo rack 12. Multiple limit frames 14 can realize the limiting of the cargo basket, and there is no need to use bolts to fix the cargo basket, thereby improving the convenience and practicality of the equipment.

[0029] Working principle: When the frame needs to be carried and disassembled, first disassemble the cargo rack 12 and the vertical rod 4, pull the cargo rack 12 upward, and the cargo rack 12 drives the two card plates 10 to move upward. When the two card plates 10 are completely out of the card slots 15, the cargo rack 12 is separated from the vertical rod 4, and then separate the backrest frame 6 from the vertical rod 4, squeeze the two push rods 505, and the push rod 505 squeezes the lock frame 503 to rotate and squeeze the spring 504 on one side. When the lock buckle of the lock frame 503 is detached from the card block 8, pull the backrest frame 6 upward, and the backrest frame 6 drives the two plug blocks 7. When the two plug blocks 7 are out of the two locking boxes 501, , then the disassembly of the backrest frame 6 is completed. When installing the cargo rack 12, just insert the card plate 10 into the card slot 15. When installing the backrest frame 6, insert the insertion block 7 into the locking box 501, the insertion block 7 drives the card block 8, the card block 8 squeezes the lock frame 503, and the lock frame 503 squeezes the spring 504. When the inclined surface on one side of the lock frame 503 and the inclined surface on one side of the card block 8 are out of contact, the spring 504 pushes the lock frame 503 to be stuck on the card block 8, then the rapid assembly of the backrest frame 6 is completed, and then the cargo basket can be placed between the four limit frames 14. The limit frame 14 can realize the limitation of the cargo basket, and there is no need to use bolts to install the cargo basket, thereby improving the practicality of the equipment.
