DETAILED DESCRIPTION

[0025] The utility model discloses a rollover handcart. An implementation mode of the utility model is described in detail below in conjunction with the accompanying drawings.

[0026] Combination Figure 1 and Figure 2 As shown, the rollover trolley includes a chassis 1, a front U-shaped frame 2, a rear U-shaped frame 3 and a vehicle box 6. The chassis 1 is a frame structure composed of a plurality of cross beams, including a first cross beam 101 and a second cross beam 102. The first cross beam 101 is located at the front side of the chassis 1, and the second cross beam 102 is located at the rear side of the chassis 1. Figure 3 As shown, the openings of the front U-shaped frame 2 and the rear U-shaped frame 3 are both downward, and wheels are movably connected to the two sides through axles. The top of the front U-shaped frame 2 is movably connected to the bottom of the first crossbeam 101 and can rotate relative to the first crossbeam 101. The front side of the front U-shaped frame 2 is detachably fixedly connected to a pull rod 4, and the front end of the pull rod 4 is hinged to the bottom of a hand handle 5.

[0027] In this embodiment, the truck bed is a metal mesh structure. In addition, the truck bed can also be integrally formed of plastic. Figure 4 and Figure 5 As shown, the truck bed 6 includes a bottom plate 601 and side plates 602 surrounding the top of the bottom plate 601 on four sides. The bottom of each side plate 602 is movably connected to the bottom plate 601 through a pin 603 that cooperates with a sleeve, and adjacent side plates 602 are detachably fixedly connected through an L-shaped lock 604. In this embodiment, the bottom plate 601 and each side plate 602 are in a mesh structure. The user opens each L-shaped lock 604 to allow each side plate 602 to flip downward along the pin 603. A first support beam 7 is fixed to the front side of the bottom of the truck bed 6, and a second support beam 8 is fixed to the rear side. The ends of the first support beam 7 and the second support beam 8 are each provided with a through hole. The truck bed 6 is set on the top of the chassis 1, and the left and right sides of the bottom of the truck bed 6 are movably connected to the chassis 1 through a flipping structure. As shown Figure 6 As shown, the flip structure includes a connecting rod 9, a sleeve and a torsion spring. The middle part of the connecting rod 9 is bent to form a handrail 901. Both sides of the connecting rod 9 are cut along a direction parallel to the axis to form an I-shaped clamping portion 902. The sleeve includes a first sleeve 10 and a second sleeve 11. A pair of first sleeves 10 are fixed on the left and right sides of the bottom of the truck bed 6. The second sleeve 11 is fixed to the ends of the first beam 101 and the ends of the second beam 102. The first sleeve 10, the second sleeve 11 and the through holes on the first beam 101 and the second beam 102 are coaxial. Figure 7 and Figure 8 As shown, the connecting rod 9 is adapted to be arranged in the first sleeve 10, the second sleeve 11 and the through hole, and the two sides of the handrail 901 are connected to the first sleeve 10 through a torsion spring. The connecting rod 9 can rotate in the first sleeve 10, the second sleeve 11 and the through hole. The upper part of the second sleeve 11 has an opening that can be adapted to the clamping part 902, and the clamping part 902 is placed in the second sleeve 11 through the opening and can be clamped with the opening.

[0028] The user can move the vehicle by pulling the wheel by hand by pulling the handle 5. The top of the front U-shaped frame 2 is movably connected to the chassis 1, which can realize turning operation and improve the user experience. The handrail 901 of the connecting rod 9 faces inward under the action of the torsion spring. At this time, the clamping part 902 is staggered with the opening of the second sleeve 11, which is convenient for fixing the truck bucket 6 and the chassis 1 and preventing the clamping part 902 from being separated from the opening of the second sleeve 11 during movement. When the user needs to tip the truck bucket 6 to unload, the handrail 901 on one side is flipped from the inside to the outside. At this time, the clamping part 902 just corresponds to the opening of the second sleeve 11. Then the user pulls up the handrail 901 on one side, and the connecting rod 9 is connected to the through holes at the ends of the first support beam 7 and the second support beam 8 through the first sleeve 10 fixed on one side of the bucket 6, driving the bucket 6 to move upward, and at the same time, the clamping part 902 of the connecting rod 9 is separated from the second sleeve 11 at the opening, and the bottom plate 601 of the bucket 6 is away from the chassis 1, and at the same time, the other side of the bucket 6 rotates along the connecting rod 9, so that the bucket 6 can be smoothly turned over. When it is necessary to reset, pull the handrail 901 downward, and the connecting rod 9 cooperates with the first sleeve 10, the first support beam 7 and the second support beam 8 to drive the bucket 6 to move downward, so that the bottom plate 601 of the bucket 6 is close to the chassis 1, and at this time, the clamping part 902 of the connecting rod 9 corresponds to the opening of the second sleeve 11, and can be placed in the second sleeve 11 from the opening of the second sleeve 11. After the user releases his hand, the armrest 901 of the connecting rod 9 automatically rotates to the inside under the action of the torsion spring, so that the clamping portion 902 is offset from the opening of the second sleeve 11 .

[0029] The following is combined with Fig. 9Another embodiment of the utility model is described in detail. In this embodiment, the truck bed 6 is integrally formed of plastic material, and the protruding connecting parts 12 on both sides of the bottom of the truck bed 6 replace the first support beam 7 and the second support beam 8 in the above embodiment. The remaining structure is the same as the above embodiment.

[0030] like Fig. 9 As shown, a pair of connecting parts 12 protrude from both sides of the bottom of the bucket, and the connecting parts 12 have through holes that can be matched with the connecting rod 9. There is a spacing between the two connecting parts 12 on each side, and a pair of first sleeves 10 are arranged in the spacing, and the first sleeves 10 are detachably fixedly connected to the bucket 6. A second sleeve 11 is arranged on the outside of the connecting part 12, and the bottom of the second sleeve 11 is detachably fixedly connected to the chassis 1. The through hole, the first sleeve 10 and the second sleeve 11 are coaxial, and the connecting rod 9 is adapted to be arranged in the first sleeve 10, the through hole and the second sleeve 11, and can be rotated in the first sleeve 10, the second sleeve 11 and the through hole. The upper part of the second sleeve 11 has an opening that can be matched with the clamping part 902, and the clamping part 902 is placed in the second sleeve 11 through the opening and can be clamped with the opening.
