DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0018] Specific embodiments of the disclosure of a round-up foldable handcart are shown in FIGS. 1-7. The round-up foldable handcart includes front and rear upright columns 4 and 21 at left and right sides, front and rear folding frames 3 and 23, left and right folding frames 20 and 24, and a folding base. Front and rear wheels 6 and 17 are correspondingly arranged on the left and right front upright columns 4 and the left and right rear upright columns 21. Front fixed seats 1 and front bases 11 are correspondingly fixed at upper and lower ends of the left and right front upright columns 4; and front sliding seats 8 are correspondingly arranged at the middle. Rear fixed seats 22 and rear bases 18 are correspondingly fixed at the upper and lower ends of the left and right rear upright columns 21; and rear sliding seats 19 are correspondingly arranged at the middle. The front and rear folding frames 3 and 23 are correspondingly hinged to the front and rear fixed seats 1 and 22 and the front and rear sliding seats 8 and 19 at front and rear sides. The left and right folding frames 20 and 24 are correspondingly hinged to the front and rear fixed seats 1 and 22 and the front and rear sliding seats 8 and 19 at the left and right sides. The folding base includes front and rear base connecting rods 12 and 16, front and rear hinging seats 13 and 15 and a handle 14. The front and rear hinging seats 13 and 15 are correspondingly fixedly connected with both ends of the handle 14. The front base connecting rod 12 is correspondingly connected among the front hinging seat 13 and the left and right front bases 11 in an upward-folding manner. The rear base connecting rod 16 is correspondingly connected among the rear hinging seat 15 and the left and right rear bases 18 in the upward-folding manner. When the handle 14 is lifted for folding, the front and rear base connecting rods 12 and 16 pull the four front and rear upright columns 4 and 21, the front and rear folding frames 3 and 23 and the left and right folding frames 20 and 24 to be rounded up toward the center; and the four front and rear upright columns 4 and 21, the front and rear folding frames 3 and 23 and the left and right folding frames 20 and 24 do not scatter when the handcart is lifted due to the action of gravity, thereby facilitating transportation.

[0019] To facilitate movement, the handcart further includes a hand-pulling device. The hand-pulling device includes second steering joints 10 correspondingly fixed on the left and right front upright columns 4, second steering joints 10 correspondingly hinged on the first steering joints 9, a hand-pull rod connecting seat 5 and a hand-pull rod 2 connected on the hand-pull rod connecting seat 5. Hand-pull connecting rods 7 are correspondingly hinged among the hand-pull rod connecting seat 5 and the first steering joints 9 at the left and right sides.

[0020] To facilitate folding, the front and rear folding frames 3 and 23 are formed by hinging two groups of X-shaped folding fork rods 25. The left and right folding frames 20 and 24 are formed by hinging two or more groups of X-shaped folding fork rods 25, and are formed by hinging four groups of X-shaped folding fork rods 25 in the present embodiment.

[0021] The above only describes an embodiment of the disclosure, and does not limit the disclosure in any form. All simple amendments, equivalent changes or modifications made without departing from the technical solutions of the disclosure shall fall into the protection scope of the disclosure.
