A plurality of card bead communication holes 8 are provided in the middle of the plug-in sleeve 7, and the inner walls of the plurality of card bead communication holes 8 are slidably connected with card beads 9. An adjusting sleeve 5 is slidably connected to the outer wall of the plug-in sleeve 7, and a guide slope 10 is provided on the top of the inner wall of the adjusting sleeve 5. The diameter of the inner wall of the adjusting sleeve 5 is larger than the diameter of the outer wall of the plug-in sleeve 7, and the diameter of the top of the guide slope 10 on the inner wall of the plug-in sleeve 7 is adapted to the diameter of the inner wall of the plug-in sleeve 7. The inner wall of the cylinder 7 is plugged with a plug-in column 13, and a clamping annular groove 15 is provided in the middle of the plug-in column 13. The bottom end of the plug-in column 13 is fixedly connected to a connecting bearing 12, and the bottom end of the connecting bearing 12 is fixedly connected to a universal wheel 6. The universal wheel 6 is rotatably connected to the plug-in column 13 through the connecting bearing 12. A compression spring 11 is provided between the top surface of the adjusting sleeve 5 and the top surface of the inner wall of the mounting groove 3. The adjusting sleeve 5 is pressed to the top of the blocking flange 4 under the push of the compression spring 11. When the adjusting sleeve 5 is fully pressed down to the top of the blocking flange 4, one end of the card bead 9 can be pushed into the inside of the clamping annular groove 15 through the guide slope 10. When the adjusting sleeve 5 is lifted, the card bead 9 can fall out of the inside of the clamping annular groove 15.

[0024] As an optional technical solution of the present invention, the distance from the inner wall of the adjusting sleeve 5 to the inner wall of the plug-in sleeve 7 is adapted to the length of the card bead 9, both ends of the card bead 9 are arc-shaped, and the diameter of the card bead 9 is adapted to the width of the inner wall of the clamping annular groove 15. The arc-shaped structure is used to guide the card bead 9 to slide, and the diameter of the card bead 9 can clamp the clamping annular groove 15 for fixation.

The guiding bevel 14 on the top of the plug-in column 13 is used to guide the card bead 9 to be pushed open. At the same time, the guiding slope on the top of the inner wall of the clamping annular groove 15 also facilitates pulling down and pushing open the card bead 9, thereby achieving the purpose of facilitating plugging and unplugging.

[0028] As an optional technical solution of the present invention, a pulling rod 2 is slidably connected to the middle of one side of the outer wall of the box body 1, and the pulling rod 2 is used to facilitate the movement of the suitcase.

[0029] A suitcase with detachable wheels, the working principle of which is as follows:

[0030] 1) By pulling the adjustment sleeve 5 upward, the bead 9 has space to be pushed outward, so that the bead 9 can be pushed outward when the plug-in column 13 is inserted into the plug-in sleeve 7;

[0031] 2) The plug-in column 13 is fully inserted into the plug-in sleeve 7, and then the adjusting sleeve 5 is loosened. Under the push of the compression spring 11, the adjusting sleeve 5 is pressed down to the top of the blocking flange 4. The guide slope 10 guides the clamping bead 9 to the inner wall of the plug-in sleeve 7, thereby pushing the clamping bead 9 into the inside of the clamping annular groove 15, thereby clamping and fixing the plug-in column 13;

[0032] 3) When disassembling, pull the adjusting sleeve 5 upwards, then pull down the plug post 13, and push the card bead 9 outwards to escape from the clamping annular groove 15 under the guidance of the guide slope, so that the plug post 13 can be pulled out.

[0033] When the locking pin 13 is in the unlock position, the locking pin 9 is pushed outwards by the guide bead 14 on the top of the locking pin 13, so that the locking pin 9 can be fully inserted into the locking pin 13. Then, the locking pin 9 is released and the locking pin 9 is pressed down to the top of the blocking flange 4 under the push of the compression spring 11. The locking pin 9 is pushed toward the inner wall of the locking pin 7 by the guide slope 10, thereby pushing the locking pin 9 into the inside of the clamping annular groove 15 to achieve the clamping and fixing of the locking pin 13. Similarly, by pulling the adjusting sleeve 5 upwards, the locking pin 13 can be directly pulled out, thereby achieving the purpose of facilitating the disassembly and replacement of the universal wheel 6. The guiding bevel 14 on the top of the locking pin 13 is used to guide the locking pin 9 to be pushed away. At the same time, the guiding slope on the top of the inner wall of the clamping annular groove 15 also facilitates the downward pulling and pushing of the locking pin 9, achieving the purpose of facilitating insertion and removal.
