The first push rod One end of the 331 facing the recess 14 encloses the second push rod 332. The second push rod 332 is used to be pushed by the elastic member 34 to move the first push rod 331 along the chute 32 to push the brake 40 to rotate.

As shown in Figures 2, 3, and 5 to 8, in one embodiment of the present invention, the brake 40 is used to prevent the two wheels 20 from rotating for braking. The brake 40 includes a rotating piece 41, a protruding piece 42, a point shaft 43, a turn shaft 44, and a retaining groove 45. The rotary piece 41 has an L-like structure. The protruding piece 42 is connected to the rotating piece 41, and the protruding piece 42 is used to be pushed by an external force (for example, the user presses the foot) to drive the rotating piece 41 to rotate. The fulcrum shaft 43 is provided on the rotary piece 41 and passes through the hole 11, and the fulcrum shaft 43 serves as a fulcrum for the rotation of the rotary piece 41. The brake shaft 44 is disposed on the rotary piece 41 and passes through the curved through hole 12, and the brake shaft 44 is used to move up and down in accordance with the rotation of the rotary piece 41. When the rotary piece 41 is not rotated in a first direction A, the brake shoe 44 does not rise and does not enter any of the brake grooves 212. When the rotating piece 41 is pivoted with the fulcrum shaft 43 and rotates along the first direction A, the boring axle 44 moves along the curved through hole 12 and rises, and the two ends of the boring axle 44 respectively enter the two wheels 20 One of the wheel bodies 212 of the wheel body 21; thereby, the brake shaft 44 and the brake groove 212 are mutually locked to prevent the wheel 20 from rotating to achieve the braking effect. The locking groove 45 fixes the spherical end of the first push rod 331.

When the user wants to make the trunk wheel structure 1 brake, as shown in FIG. 6, the user must first press the protruding member 42 to cause the protruding member 42 to drive the rotating piece 41 with the fulcrum shaft 43 as a fulcrum and along the first direction. A rotation; at this time, the brake shaft 44 to which the rotary piece 41 is attached is driven by the rotary piece 41 to move and rise along the curved through hole 12; as shown in FIGS. 4, 6, and 8, the raised The two ends of the axle 44 are respectively inserted into one of the wheel slots 212 of the wheel body 21 of the two wheels 20; whereby the axle 44 is engaged with the brake groove 212 to prevent the wheel 20 from rotating to achieve the braking effect.

When the user wants to release the brake of the trunk wheel structure 1, as shown in FIG. 5 and FIG. 6, the user does not need to apply pressure to the protruding member 42, so that the elastic member 34 pushes the second push rod 332. The moving second push rod 332 pushes the first push rod 331 such that the first push rod 331 moves along the chute 32 toward the retaining groove 45 to push the rotating piece 41 of the brake 40 in the opposite direction of the first direction A. Rotate. The rotating piece 41 rotating in the opposite direction of the first direction A causes the brake shaft 44 to move, so that the brake shaft 44 moves along the curved through hole 12 and is lowered. As shown in FIG. 4, FIG. 5 and FIG. 7, the two ends of the lowered brake shaft 44 are respectively separated from the brake grooves 212 of the wheel main body 21 of the two wheels 20, and moved to a position closer to the central through hole 211; The brake axle 44 does not interlock with any of the brake grooves 212, so that the braking effect is released.

With the design of the luggage wheel structure 1 of the present invention, the user can make the luggage wheel structure 1 produce a braking effect at any time through a simple pressing action; and when the user no longer presses, the trunk wheel structure 1 The brake effect will be lifted.

It should be noted that the above is only an embodiment, and is not limited to the embodiment. For example, those who do not deviate from the basic structure of this new model shall be the scope of rights claimed in this patent, and shall be subject to the scope of patent application.
