As shown in Figure 2 and Figure 6, main connector 10 is to connect two wheels 20, push piece 30, brake 40 and top cover 50.Main connector 10 includes hole 11, arc-shaped through-hole 12, connecting shaft 13, groove 14 and top cover connector 15.Arc-shaped through-hole 12 are located at 11 side of hole, and arc-shaped through-hole 12 is to allow brake 40 to move along the arc track of arc-shaped through-hole 12.Connecting shaft 13 Both ends connect two wheels 20.Push piece 30 is located at groove 14.Top cover connector 15 connects top cover 50, top cover Body connector 15 includes connecting hole 151, fixes bar 152 and screw 153.It fixes bar 152 and screw 153 is located in connecting hole 151. Fixing bar 152 has internal screw thread to fix screw 153, and fix bar 152 top cover 50 can be fixed on connecting hole 151 it On, whereby, fixes bar 152 and top cover 50 and screw 153 fixes mutually.Top cover 50 is to be connected to luggage case Top, so that luggage wheel assembly minor structure 1 is in conjunction with luggage case.

As shown in Figures 2 to 4, two wheels 20 are connected to the two sides of main connector 10.Each wheel 20 includes wheel master Body 21, bearing 22, torus 23 and 24. wheel body 21 of wheel lid include center through hole 211 and even numbers brake slot 212, center Through-hole 211 is located at the center of wheel body 21, and even numbers brakes slot 212 around center through hole 211；Even numbers brakes slot 212 to match It closes brake 40 and brake function is provided.Bearing 22 is set to center through hole 211 and connects connecting shaft 13；Bearing 22 is to be cooperatively connected Axis 13 and drive wheel body 21 rotate.Torus 23 can be rubber ring, and circular wheel body 21, torus 23 is in wheel 20 when rolling on the ground, provides incabloc function.Wheel lid 24 covers wheel body 21, to protect wheel body 21.

As shown in Figure 2, Figure 5 and Figure 6, push piece 30 is to push 40 rotation of brake.Push piece 30 includes push piece main body 31, sliding slot 32, push rod group 33 and 34. push piece main body 31 of elastic component connect main connector 10 and are located at groove 14.Sliding slot 32 is set So removable that be located in sliding slot 32 in 31. push rod group 33 of push piece main body, push rod group 33 can be moved along sliding slot 32 to push and stop Vehicle 40 rotates.Elastic component 34 can be paralysis, be located in push piece main body 31 and contact push rod group 33.Push rod group 33 includes the One push rod 331 and the second push rod 332.First push rod 331 connects the second push rod 332, and the first push rod 331 can be rubber Elastic covering, the first push rod 331 are rendered as spherical and fix with brake 40 towards external one end, and the first push rod 331 is towards groove Then entangle the second push rod 332 in one end in 14.Second push rod 332 to be pushed by elastic component 34 so that the first push rod 331 along Sliding slot 32 is mobile, to push 40 rotation of brake.

As shown in Fig. 2, Fig. 3, Fig. 5 to Fig. 8, brake 40 is to prevent two rotations of wheel 20 to brake.Brake 40 Including revolving fragment 41, prodger 42, fulcrum shaft 43, brake axle 44 and fixing slot 45.Revolving fragment 41 is L shape structure.Prodger 42 Revolving fragment 41 is connected, prodger 42 drives revolving fragment 41 to rotate to be pushed (such as user is jammed on foot) by external force.Branch Point axis 43 is set to revolving fragment 41 and passes through hole 11, and fulcrum shaft 43 is to the fulcrum that rotates as revolving fragment 41.Brake axle 44 is set In revolving fragment 41 and arc-shaped through-hole 12 is passed through, brake axle 44 is gone up and down to cooperate the rotation of revolving fragment 41.When revolving fragment 41 simultaneously When not along first direction A rotation, brake axle 44 will not be risen, and will not enter any brake slot 212, when revolving fragment 41 is to prop up When point axis 43 is fulcrum and A rotates along a first direction, brake axle 44 can be moved and be increased along arc-shaped through-hole 12, and brake axle 44 both ends can respectively enter one of brake slot 212 of the wheel body 21 of two wheels 20；Whereby, brake axle 44 can and The slot 212 that brakes fixes mutually, achievees the effect that brake to prevent wheel 20 from rotating.Fixing slot 45 fixes the first push rod 331 Spherical one end.

When user wants that luggage case wheel structure 1 is allowed to brake, as shown in fig. 6, user must first jam on protrusion Part 42 allows prodger 42 to drive revolving fragment 41 using fulcrum shaft as fulcrum and A rotates along a first direction；At this point, connecting this rotation The brake axle 44 of piece 41 will receive the drive of revolving fragment 41, and moves and increase along arc-shaped through-hole 12；Such as Fig. 4, Fig. 6 and Fig. 8 institute Show, the both ends of raised brake axle 44 can respectively enter one of brake slot 212 of the wheel body 21 of two wheels 20；It borrows This, 44 meeting of brake axle and brake slot 212 fix mutually, and the effect of brake is reached to prevent wheel 20 from rotating.

When user wants to release the brake of luggage wheel assembly minor structure 1, as shown in Figure 5 and Figure 6, user is not necessary to again to prominent Part 42 applies pressure out, in this way, which elastic component 34 will push the second push rod 332, the second mobile push rod 332 will push first Push rod 331, so that the first push rod 331 is moved along sliding slot 32 to fixing slot 45, to push the revolving fragment 41 of brake 40 along the The opposite direction of one direction A rotates.The revolving fragment 41 of the opposite direction rotation of A will drive the movement of brake axle 44 along a first direction, make Brake axle 44 is obtained to move and reduce along arc-shaped through-hole 12.As shown in Fig. 4, Fig. 5 and Fig. 7, the both ends meeting of reduced brake axle 44 Respectively away from the brake slot 212 of the wheel body 21 of two wheels 20, and it is moved to the position for being closer to center through hole 211； Whereby, brake axle 44 will not fix mutually with any brake slot 212, so that braking effect releases.
