[0019] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof. Please refer to... Figure 1 and Figure 2 One embodiment of this utility model provides a multi-functional roller for dragging a suitcase, comprising: a base 10, a rotating wheel seat 20, an elastic buffer structure 30, and a plurality of wheel bodies 40; The base 10 and the rotating wheel seat 20 are slidably engaged, allowing the rotating wheel seat 20 to rise and fall relative to the base 10. The rotating wheel seat 20 and the base 10 are also rotatably engaged. An elastic buffer structure 30 is connected between the rotating wheel seat 20 and the base 10. The wheel body 40 is rotatably engaged with the rotating wheel seat 20. A braking mechanism 50 is provided on the rotating wheel seat 20, movably connected to the wheel body 40 to limit its rotation. The base 10 is used to connect to the suitcase body. When the suitcase moves, if the wheel body 40 travels on uneven ground, when it contacts a protruding part, the wheel body 40 will cause the rotating wheel seat 20 to rise adaptively. At this time, the elastic buffer structure 30 will be compressed / stretched, producing elastic deformation, thus providing a buffering effect on the wheel body 40 and the rotating wheel seat 20, reducing vibrations in the suitcase and improving its stability.

[0020] The way the rotating wheel seat 20 and the base 10 are matched can be designed according to actual needs. For example, in some optional embodiments, the base 10 is provided with a main shaft 11 and the rotating wheel seat 20 is provided with a shaft hole 21. The main shaft 11 and the shaft hole 21 are rotatably matched, and the rotating wheel seat 20 can be raised and lowered relative to the main shaft 11, so that the rotating wheel seat 20 can achieve rotation and raising and lowering relative to the base 10.

[0021] Please see Figure 3 and Figure 4 In some optional embodiments, an adjusting member 12 is provided at the bottom of the main shaft 11. The adjusting member 12 can be raised and lowered relative to the main shaft 11. After the rotating wheel seat 20 rises relative to the base 10, the bottom of the adjusting member 12 abuts against the bottom of the shaft hole 21. By adjusting the height of the adjusting member 12 relative to the main shaft 11, the height that the rotating wheel seat 20 can rise can be adjusted, thereby realizing the adjustment of the buffer distance that the rotating wheel seat 20 can achieve, which is convenient for adaptive adjustment according to different usage environments.

[0022] In some alternative embodiments, a limiting member 22 is provided in the shaft hole 21. The limiting member 22 is located between the adjusting member 12 and the main shaft 11. The limiting member 22 restricts the lifting stroke of the rotating wheel seat 20 relative to the main shaft 11. When the rotating wheel seat 20 rises to the limit position, the limiting member 22 abuts against the bottom end of the main shaft 11. When the rotating wheel seat 20 falls to the limit position, the limiting member 22 abuts against the adjusting member 12.

[0023] Please see Figure 5 In some optional embodiments, a connecting seat 13 is rotatably disposed at the bottom of the base 10. The connecting seat 13 is disposed between the rotating wheel seat 20 and the base 10. An elastic buffer structure 30 abuts against the connecting seat 13. The elastic force of the elastic buffer structure 30 drives the connecting seat 13 to press against the base 10. The connecting seat 13 is used to cooperate with the elastic buffer structure 30, thereby simplifying the structure of the base 10 and facilitating production and assembly. In this embodiment, the connecting seat 13 is also sleeved on the main shaft 11 and can rotate relative to the main shaft 11. The connecting seat 13 and the rotating wheel seat 20 are circumferentially limited, so that the connecting seat 13 and the rotating wheel seat 20 cannot rotate relative to each other, but can only move up and down relative to each other. The top of the connecting seat 13 has a convex arc surface that abuts against the base 10, so that the rotation of the connecting seat 13 and the rotating wheel seat 20 can be reduced by the arc surface.

[0024] In some optional embodiments, the rotating wheel seat is provided with a groove 23 arranged around the shaft hole 21, and a slip ring 14 is provided at the bottom of the connecting seat 13. The slip ring 14 extends movably into the groove 23. When the rotating wheel seat 20 is raised and lowered, the groove 23 can be raised and lowered relative to the slip ring 14. An elastic buffer structure 30 is disposed in the groove 23 and abuts against the slip ring 14. The cooperation between the slip ring 14 and the groove 23 can improve the raising and lowering stability of the rotating wheel seat 20. In this embodiment, the elastic buffer structure 30 includes multiple springs, which are arranged around the main shaft 11 and disposed in the groove 23. The multiple springs improve the stability of the rotating wheel seat 20 under force. In this embodiment, the slip ring 14 is provided with a circumferential limiting protrusion on its outside, and a limiting groove is provided in the groove 23. The circumferential limiting protrusion and the limiting groove cooperate to limit the slip ring 14 from rotating relative to the groove 23, thereby limiting the relative rotation between the connecting seat 13 and the rotating wheel seat 20.

[0025] Please see Figure 6 The braking mechanism 50 is used to limit the rotation of the wheel 40. Its specific structure can be designed according to actual needs. For example, in some optional embodiments, the braking mechanism 50 includes a limiting toothed plate 51 movably mounted on the rotating wheel seat 20 and a return spring 52 disposed between the limiting toothed plate 51 and the rotating wheel seat 20. A limiting gear 41 is provided on the wheel 40. After the limiting toothed plate 51 moves toward the limiting gear 41, the limiting toothed plate 51 meshes with the limiting gear 41 to limit the rotation of the wheel 40. At this time, the return spring 52 generates elastic deformation. Through the stable cooperation between the limiting toothed plate 51 and the limiting gear 41, the wheel 40 can be relatively stably limited. The elastic force of the return spring 52 can drive the wheel. In this embodiment, the limiting toothed plate 51 is provided with multiple limiting teeth, and the multiple limiting teeth mesh with the limiting gear 41.

[0026] Please see Figure 7In some optional embodiments, the braking mechanism 50 further includes a rotary button 53 rotatably disposed on the outside of the rotating wheel seat 20. The rotary button 53 is provided with a pushing part 54 and a positioning part 55. After the rotary button 53 is rotated, it can push the limiting tooth plate 51 toward the limiting gear 41 through the pushing part 54. The positioning part 55 is positioned and engaged with the side of the limiting tooth plate 51 away from the return spring 52. The user can rotate the rotary button 53 by stepping on it, which causes the pushing part 54 to push the limiting tooth plate 51 toward the limiting gear 41. The elastic force of the return spring 52 will press the side of the limiting tooth plate 51 away from the return spring 52 toward the positioning part 55, so that the pushing part 54 is held in position by the positioning part 55, thereby maintaining the braking state. When the brake is released, the user can step on the rotary button 53 again, which causes the pushing part 54 to move away from the limiting tooth plate 51. The limiting tooth plate 51 is also moved away from the limiting gear 41 by the return spring 52, thus achieving the effect of releasing the brake. In this embodiment, the positioning part 55 protrudes from the pushing part 54, and the positioning tooth plate 51 is provided with a positioning groove, and the positioning part 55 is positioned and engaged with the positioning groove.

[0027] In some optional embodiments, the rotating wheel seat 20 is provided with a movable cavity 24, the limiting tooth plate 51 is movably disposed within the movable cavity 24, and the pushing part 54 extends movably into the movable cavity 24. The movable cavity 24 accommodates the limiting tooth plate 51, thereby facilitating the stable movement of the limiting tooth plate 51. In this embodiment, a limiting spring is disposed between the limiting tooth plate 51 and the inner wall of the movable cavity 24.

[0028] The aforementioned multi-functional wheels for dragging a suitcase can be applied to a suitcase, which includes: a plurality of multi-functional wheels for dragging a suitcase as described above. In one embodiment, the suitcase includes a body and four multi-functional wheels for dragging the suitcase, with the bases 10 of the four multi-functional wheels for dragging the suitcase mounted on the bottom of the body.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
