DETAILED DESCRIPTION

[0030] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 9 As shown, this embodiment provides a portable trolley with a seat, including a trolley frame 1, a shelf 2, a first shaft 3, wheels 4, a support portion 5 made of a soft material, and a second connecting rod 6. There are two wheels 4, the soft material of the support portion 5 is made of fiber cloth, and the second connecting rod 6 is U-shaped. The trolley frame 1 includes a first connecting rod 11 and a connecting seat 12. The first connecting rod 11 is also U-shaped. The deployed structure of the first connecting rod 11 and the second connecting rod 6 is a cross shape, specifically, a V-shape, an X-shape, or a herringbone shape.

[0032] The first connecting rod 11 has two first holes, and the two first holes are roughly located at both ends of the first connecting rod 11. The shelf 2 has a second hole 24, and the wheel 4 has a third hole. At least part of the first axis 3 is located in the first hole, the second hole, and the third hole. The two wheels 4 can rotate around the first axis 3 relative to the shelf 2 and the first connecting rod 11, so that the portable trolley with a seat can be pushed through the two wheels 4; the wheels can also be directly connected to the shelf for rotation, or only connected to the first connecting rod for rotation, both of which can achieve the effect of movement. The shelf 2 can rotate around the first axis 3 relative to the first connecting rod 11, so that the shelf 2 can be unfolded or folded on the first connecting rod 11, which is conducive to improving the portability of the portable trolley with a seat.

[0033] The connecting seat 12 is fixedly matched with the first connecting rod 11, and the connecting seat 12 is located on the upper side of the shelf 2. The connecting seat 12 includes a second axis, which is basically parallel to the first axis 3. The second axis is located on the upper side of the first axis 3. The second connecting rod 6 has a fourth hole, and at least part of the second axis is located in the fourth hole. The second connecting rod 6 can rotate around the second axis relative to the first connecting rod 11, so that the first connecting rod 11 and the second connecting rod 6 can be folded or unfolded, which is beneficial to improve the portability of the portable trolley with a seat.

[0034] The support portion 5 is limitedly cooperated with the connecting seat 12 and the second connecting rod 6, and the second connecting rod 6 and the first connecting rod 11 can be relatively unfolded or folded, so that the support portion 5 can be folded or unfolded, which is beneficial to improving the portability of the portable trolley with a seat. In actual use, the user can sit on the unfolded support portion 5, which is beneficial to provide rest for the user.

[0035] In one possible implementation, the shelf 2 includes a first recessed portion 21, which is recessed downward from the top wall of the shelf 2. At least part of the first connecting rod 11 is located in the first groove 211 of the first recessed portion 21. There are two first recessed portions 21, and the two ends of the first connecting rod 11 are respectively located in the first grooves 211 of the two first recessed portions 21. This further helps to improve the portability of the portable trolley with a seat.

[0036] In one possible implementation, the shelf 2 includes a first protrusion 22, which is located in the first groove 211. The first protrusion 22 is arranged to protrude inward from the inner side wall forming the first groove 211, and the first protrusion 22 is arranged to abut against the side wall of the first connecting rod 11, which is conducive to keeping the first connecting rod 11 in the expanded state.

[0037] In one possible implementation, the connecting seat 12 includes a main body 121 and a splint portion 122. The main body 121 and the splint portion 122 are limited in position. The main body 121 and the splint portion 122 can be fixed by bolts. Part of the support portion 5 is located between the main body 121 and the splint portion 122. The splint portion 122 can press the support portion 5 against the main body 121, which is conducive to improving the load-bearing capacity of the support portion 5.

[0038] In one possible implementation, the main body 121 includes a second protrusion, which is protruded outward from the outer wall of the main body 121. There are two second protrusions, which are located on both sides of the main body 121. The two second protrusions are abutted against the second connecting rod 6.

[0039] In one possible implementation, the main body 121 has a first limiting hole 1211, the support part 5 has a second limiting hole 51, and part of the first connecting rod 11 is located in the first limiting hole 1211 and the second limiting hole 51, further improving the matching strength between the connecting seat 12 and the support part 5; a retractable handle is provided on the first connecting rod 11, and the handle passes through the first limiting hole 1211.

[0040] In one possible implementation, the shelf 2 includes a second recessed portion 23, which is recessed inward from the outer wall of the shelf 2, and part of the second connecting rod 6 is located in the second groove 231 of the second recessed portion 23, which helps to further improve the portability of the portable trolley with a seat.

[0041] In a possible implementation, part of the support portion 5 encloses the third limiting hole 52 , the support portion 5 can be kept in the enclosed state by sewing thread, and part of the second connecting rod 6 is located in the third limiting hole 52 .

[0042] The second connecting rod 6 forms an upper end portion at the portion between the second shaft 123 and the third limiting hole 52, and forms a lower end portion at the portion below the second shaft 123. The upper end portion is bent relative to the lower end portion, so that the upper end portion can be more stable when the support part 5 is unfolded and used as a seat, making it easier to use.

[0043] In a possible implementation, the portable trolley with a seat includes casters 7 , which are limitedly engaged with the second connecting rod 6 . There are two casters 7 , which are respectively engaged at both ends of the second connecting rod 6 .

[0044] In one possible implementation, two wheels 4 are provided, the front end of the shelf 2 is provided with two wheels 4, and the rear end of the shelf 2 is provided with two downwardly protruding placement ends. When the shelf 2 is at rest, the two wheels 4 and the two placement ends form a placement end surface with four resting points, which facilitates the placement of the shelf.

[0045] In a possible implementation, four wheels are provided, with two wheels respectively provided at the front and rear ends of the shelf. The four front and rear wheels 4 enable the shelf 2 to be moved by the wheels 4 when it is placed stationary.

[0046] In one possible implementation, the shelf is provided with at least two groups of second holes 24 for installing wheels, and the second holes are arranged longitudinally. In this embodiment, three groups of second holes 24 are preferably provided. The wheels 4 can be installed in the second holes 24 at different heights according to their sizes, so that the shelf 2 can be conveniently moved with the wheels 4. When it is necessary to increase the height of the shelf 2 from the ground, the shelf can also be installed on the second hole 24 at the lowest end.

[0047] In one possible implementation, the portable trolley with a seat includes a limiting component (not shown in the figure), which can be a rod. One end of the limiting component is rotatably engaged with the first rod 11, and the other end of the limiting component is rotatably engaged with the second rod 6. Part of the support portion is located above the second shaft 123, and part of the limiting component is located below the second shaft 123. The limiting component, the first rod 11, and the second rod 6 constitute a planar connecting rod mechanism. The unfolded structure of the limiting component, the first rod 11, and the second rod 6 is A-shaped, and the limiting component can support the first rod 11 and the second rod 6.

[0048] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
