For ease of understanding, in the horizontal direction in the present embodiment, the longitudinal direction of the carrier 2 is defined as a first direction, and the width direction of the carrier 2 is defined as a second direction, and a description will be given of the folding luggage cart based on this.

The embodiment of the application discloses a folding luggage trolley. Referring to fig. 1, the folding luggage cart includes a drawbar 1, a carrier 2, a rotating member 3, front casters 4, and universal wheels 5.

With continued reference to FIG. 1, the carrier member 2 is of unitary construction, with the carrier member 2 extending in a first direction. The bearing piece 2 is used for bearing objects, and the bearing piece 2 is made of metal materials, so that the overall hardness and the connection strength of the bearing piece 2 are increased, and meanwhile, the bearing piece 2 is not easy to deform, and compared with the background art, the service life of the bearing piece 2 is prolonged.

With continued reference to fig. 1, the carrier 2 is provided with a plurality of avoidance holes 23, and the plurality of avoidance holes 23 are symmetrical to each other. The plurality of clearance holes 23 not only reduces the overall mass of the carrier body 2, but also increases the overall aesthetics of the carrier body 2 due to the symmetry of the plurality of clearance holes 23. Meanwhile, when the surface of the carrier 2 has water, the plurality of avoidance holes 23 are also convenient for rapidly discharging the water on the surface of the carrier 2, so that the surface of the carrier 2 cannot accumulate excessive water.

With continued reference to fig. 1, in this embodiment, the number of rotary members 3 is two, and both rotary members 3 are rotatably connected to the carrier member 2. The pull rod 1 comprises a holding part 11 and two telescopic parts 12, the holding part 11 extends along the second direction, two ends of the holding part 11 are fixedly connected with one ends of the two telescopic parts 12 respectively, and the other ends of the two telescopic parts 12 are fixedly connected with the two rotating pieces 3 respectively. The telescopic part 12 can change its own length in a telescopic manner, thereby facilitating the adjustment of the overall length of the pull rod 1.

With continued reference to fig. 1, the support 2 is provided with a positioning groove 21, and when the pull rod 1 is folded into the positioning groove 21, the surface of the pull rod 1 is flush with the surface of the support 2. The positioning groove 21 has a positioning function on the pull rod 1, so that a user can fold the pull rod 1 into the positioning groove 21 conveniently. Meanwhile, when the pull rod 1 is folded into the positioning groove 21, the surface of the pull rod 1 is flush with the surface of the bearing object 2, so that the overall aesthetic property is improved, and meanwhile, when a user contacts the pull cart, the pressure of the pull cart to the user is reduced, and the pull cart has a protective effect on the user.

Referring to fig. 2 and 3, each rotary member 3 includes an aluminum-type pipe 31, a rotary shaft 32, and an insert 33, one end of the aluminum-type pipe 31 is provided in an opening, and an end of the tie rod 1 is inserted into the aluminum-type pipe 31. The rotation shaft 32 extends in the second direction, the rotation shaft 32 passes through the carrier 2 and the aluminum pipe 31 in turn, and the rotation shaft 32 is rotatably connected with the carrier 2. One end of the rotating shaft 32 is fixedly provided with an anti-falling block 321, and the side wall of the anti-falling block 321 is abutted against the outer side wall of the carrier 2. The other end of the rotating shaft 32 is provided with a threading hole 322, the inserting piece 33 is inserted into the threading hole 322, and the inserting piece 33 is abutted against the outer side wall of the other side of the bearing piece 2. Since the anti-falling block 321 and the inserting piece 33 are respectively abutted against two opposite sides of the carrier 2, the anti-falling block 321 and the inserting piece 33 have a positioning effect on the rotating shaft 32 so that the rotating shaft 32 cannot move along the axis direction of the rotating shaft; meanwhile, as the rotating shaft 32 is rotationally connected with the bearing piece 2, the pull rod 1 drives the aluminum pipe 31 to rotate around the rotating shaft 32 in the process of rotating the pull rod 1 by a user, so that the pull cart can be conveniently folded and unfolded; simultaneously, the user can also take out the insert 33 from the threading hole 322, and the clamping effect of the insert 33 and the anti-falling block 321 on the bearing piece 2 is relieved, so that the rotary shaft 32 is conveniently pulled out by the staff, the aluminum pipe 31 and the wire drawing are conveniently detached from the bearing piece 2 by the staff, and the convenience of replacing the handle by the user is improved.

Referring to fig. 3, in the present embodiment, the insert 33 is a wire 323, and the wire 323 is not only easy to bend and deform, so as to ensure that the wire 323 is not easy to fall out from the through hole 322, but also ensure the hardness of the wire 323, and prolong the overall service life.

Referring to fig. 4 and 5, the inner sidewall of the positioning groove 21 is fixedly provided with a limiting portion 22, the outer sidewall of the aluminum pipe 31 is fixedly provided with a flange 311, the flange 311 is made of an elastic material, and the specific flange 311 may be made of rubber. When the aluminum pipe 31 is rotated to a vertical state, the side wall of the flange 311 abuts against the side wall of the stopper 22. Because the flange 311 is made of elastic material, the user rotates the handle to drive the aluminum pipe 31 to rotate in the process of rotating the handle, the aluminum pipe 31 drives the flange 311 to rotate, and when the flange 311 rotates to the position of the limiting part 22, the limiting part 22 extrudes the elastic material to enable the elastic material to elastically deform, so that the user can rotate the handle to a vertical state conveniently. At this time, the limiting part 22 and the carrier 2 have clamping effect on the aluminum pipe 31, so that the aluminum pipe 31 is ensured to be in a vertical state, and the handle is ensured to be in a vertical state.

Referring to fig. 5, the limiting portion 22 is provided with a first rounded corner 24, and the flange 311 is provided with a second rounded corner 312. When the aluminum pipe 31 is rotated to the position of the limit part 22, the first rounded corner 24 and the second rounded corner 312 reduce the contact area between the limit part 22 and the flange 311, thereby reducing the friction between the limit part 22 and the flange 311, so that the user has a labor-saving effect in the process of rotating the pull rod 1.

Referring to fig. 1 and 2, in the present embodiment, the number of front casters 4 is two, and both front casters 4 are disposed at the front end of the carrier 2. Specifically, the two front casters 4 are fixedly connected through a rotating rod 6, the rotating rod 6 extends along the second direction, the two front casters 4 are respectively positioned at two ends of the rotating rod 6, and the rotating rod 6 penetrates through the bearing piece 2 and is rotationally connected with the bearing piece 2.
