Detailed Description

As shown in fig. 1-2, a folding cart comprises a first vertical rod 11, a second vertical rod 12, a third vertical rod 13 and a fourth vertical rod 14, wherein the lower ends of the first vertical rod 11, the second vertical rod 12, the third vertical rod 13 and the fourth vertical rod 14 are respectively connected with a wheel 1, the first vertical rod 11, the second vertical rod 12, the third vertical rod 13 and the fourth vertical rod 14 are respectively and rotatably connected with a first folding rod 21, a second folding rod 22, a third folding rod 23 and a fourth folding rod 24, the first folding rod 21 and the third folding rod 23 are hinged through a U-shaped connecting piece 2, the second folding rod 22 and the fourth folding rod 24 are also hinged through the U-shaped connecting piece 2, and the opening end of the U-shaped connecting piece 2 faces downwards. With the above structure, when the folding cart is in the unfolded state, that is, when the included angle between the first folding bar 21 and the third folding bar 23 is about 180 degrees, the first folding bar 21 and the third folding bar 23 are abutted against the U-shaped connecting piece 2, so that the first folding bar 21 and the third folding bar 23 are kept collinear, and do not continue to rotate, and similarly, the second folding bar 22 and the fourth folding bar 24 are kept collinear.

A plurality of first cross bars 5 are arranged between the first 21 and second 22 folding bars and between the third 23 and fourth 24 folding bars. The number of first cross bars 5 may be set according to the size and strength requirements, and in this embodiment, 2 first cross bars 5 are provided between the first folding bar 21 and the second folding bar 22 and between the third folding bar 23 and the fourth folding bar 24, respectively.

The first vertical rod 11 is rotatably connected with the first supporting rod 3, the third vertical rod 13 is rotatably connected with the second supporting rod 4, or the second vertical rod 12 is rotatably connected with the first supporting rod 3, and the fourth vertical rod 14 is rotatably connected with the second supporting rod 4; the first support rod 3 is hinged with the second support rod 4.

The first support rod 3 and the second support rod 4 are provided with support blocks 6, and when the folding trolley is in an unfolding state, the support blocks 6 are abutted with the first cross rod 5. The whole rigidity and the loading capacity of the folding trolley are improved through the support rods and the support blocks 6.

The first upright 11 and the second upright 12 are connected through a first connecting rod 15 to form an integrated first support frame, and the third upright 13 and the fourth upright 14 are connected through a second connecting rod 16 to form an integrated second support frame. The first link 15 and the second link 16 may be used as handrails to push and pull the folding cart and may also be used for hanging things.

A second cross bar 17 is fixedly connected between the first vertical rod 11 and the second vertical rod 12 and between the third vertical rod 13 and the fourth vertical rod 14. The second cross bar 17 is provided with a bracket 7, and the bracket 7 is hinged with a handle component.

The wheels 1 connected with the first vertical rod 11 and the second vertical rod 12 are universal wheels, and the wheels 1 connected with the third vertical rod 13 and the fourth vertical rod 14 are directional wheels.

A brake assembly 10 is arranged between the orientation wheels. Under the condition that the movement of the wheel 1 needs to be limited, the brake assembly 10 is stamped down, so that the directional wheel cannot rotate, and the brake assembly 10 is of an existing structure and will not be described herein.

When folding is needed, the first cross bars 5 opposite to the two sides of the U-shaped connecting piece 2 are pulled upwards respectively, so that the first cross bars 5 on the support frame are separated from the support frame, at the moment, the first folding bars 21, the second folding bars 22, the third folding bars 23 and the fourth folding bars 24 are folded upwards, meanwhile, the included angles of the first support bars 33 and the second support bars 44 are reduced, and the first vertical bars 11 and the third vertical bars 13 are pushed towards the middle, so that folding can be completed. When the expansion is needed, the steps are executed in reverse order.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be appreciated by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the utility model, and that simple modifications and substitutions by those skilled in the art are within the scope of the utility model without departing from the spirit and scope of the utility model.
