[0021] Please see Figure 1-5 This utility model provides a technical solution: a conveniently assembled and disassembled bag, including a bag body 1, an internal placement groove 2, and a mating groove for placing a telescopic pull rod 7 on the top of the bag body 1. The inner wall of the placement groove 2 is welded and fixed to a horizontal plate 3. The horizontal plate 3 is rotatably connected to the outer side of a rotating cylinder 4. The outer side of the rotating cylinder 4 is welded and fixed to a handwheel 5. A threaded rod 6 is provided inside the handwheel 5. The telescopic pull rod 7, which is a U-shaped rod, is placed inside the placement groove 2. The lower end of the telescopic pull rod 7 is welded and fixed to a fixing block 8. A circular insertion hole is provided on the side of the rotating cylinder 4. A cover plate 9 is provided on the side of the bag body 1. The cover plate 9 is rotatably connected to the inner wall of the placement groove 2 via a hinge shaft. The side of the cover plate 9 is welded and fixed to a pull plate. A damping block is provided on the hinge shaft of the cover plate 9 to prevent the cover plate 9 from deflecting due to the tilting of the bag body 1.

[0022] The bottom surface of the housing 1 is welded and fixed to the mounting cylinder 10. A fixing collar 11 is fitted on the outside of the mounting cylinder 10, and a torsion spring 12 is fitted on the outside of the fixing collar 11. The bottom of the housing 1 is fixedly connected to four symmetrical torsion springs 12. The inside of the torsion springs 12 is movably inserted into the outside of the connecting cylinder 16. A sliding groove 13 and a fixing groove 14 are opened on the inner wall of the mounting cylinder 10. Four symmetrical moving wheels 15 are provided at the bottom of the housing 1. The top of the moving wheels 15 is welded and fixed to the connecting cylinder 16. The outside of the connecting cylinder 16 is welded and fixed to the slider 17.

[0023] A U-shaped placement groove 2 is provided inside the housing 1. The placement groove 2 slides with the outer side of the fixing block 8. The fixing block 8 slides inside the placement groove 2, which facilitates the disassembly and replacement of the telescopic rod 7 without affecting the telescopic extension and retraction effect of the telescopic rod 7.

[0024] The two sides of the rotating cylinder 4 are rotatably connected to the outer side of the rotating cylinder 4. The middle of the outer side of the rotating cylinder 4 is welded and fixed to the handwheel 5. Threaded grooves are opened on both sides of the inside of the rotating cylinder 4. The rotating cylinder 4 is threadedly connected to the outer side of the threaded rod 6 through the threaded grooves. The threaded rod 6 is symmetrically distributed on both sides of the rotating cylinder 4. Matching threaded grooves are opened on both sides of the inside of the rotating cylinder 4. By rotating the rotating cylinder 4 and the threaded grooves, the threaded rod 6 moves horizontally inside the rotating cylinder 4, so that the threaded rod 6 can be pulled out from the circular through hole opened on the side of the fixed block 8.

[0025] The cover plate 9 is rotatably connected to the inner wall of the placement groove 2 via a hinge shaft. The side of the cover plate 9 is welded and fixed to the pull plate. The fixing collar 11 is located on the outside of the mounting cylinder 10. The two ends of the torsion spring 12 are welded and fixed to the mounting cylinder 10 and the fixing collar 11, respectively.

[0026] The sliding groove 13 is a vertical groove, and the fixed groove 14 is a horizontal arc-shaped groove. The sliding groove 13 and the fixed groove 14 are connected. The interior of the sliding groove 13 and the fixed groove 14 slides in contact with the exterior of the slider 17. The sliding groove 13 and the fixed groove 14 are connected to form an L-shape. The elastic force of the torsion spring 12 is used to reset the mounting cylinder 10, thereby ensuring that the slider 17 is fixed in the fixed groove 14. By having the slider 17 located inside the fixed groove 14, the moving wheel 15 is prevented from detaching from the mounting cylinder 10 during use, effectively reducing the difficulty of installing and disassembling the moving wheel 15.

[0027] Working principle: During use, the movable wheels 15 at the bottom of the housing 1 facilitate the movement of the entire unit. The telescopic rod 7 is pulled out to extend and retract. When the telescopic rod 7 is damaged and needs to be replaced, manually rotate the cover plate 9, and then rotate the handwheel 5 to rotate the rotating cylinder 4, thereby driving the threaded rods 6 on both sides to move inside the rotating cylinder 4 until the threaded rods 6 are pulled out from the insertion holes on the side of the fixing block 8. The fixing block 8 can then be directly pulled out from the placement groove 2, making it easy to disassemble and replace the telescopic rod 7. Similarly, during installation, the fixing block 8 is inserted into the placement groove 2, and the rotating cylinder 4 is rotated to move the threaded rod 6 and insert it into the insertion hole inside the fixing block 8 to complete the installation of the telescopic rod 7. If the movable wheel 15 is damaged and needs to be replaced, rotate the mounting cylinder 10 to move the slider 17 inside the fixing groove 14 into the sliding groove 13, and then pull down the movable wheel 15 to let the slider 17 slide out from the sliding groove 13, thus realizing the disassembly and replacement of the movable wheel 15.
