[0027] like Figure 1-6As shown, the utility model provides a multifunctional cart, including a main frame 2, one end of the main frame 2 is fixedly connected to a push handle 1, and two U-shaped plates 9 are provided inside the main frame 2, and both sides of the U-shaped plate 9 are fixedly connected to a rotating rod 18 that penetrates the main frame 2 and is rotatably connected to the penetrating portion through a bearing. One end of the rotating rod 18 is provided with a square cover 4 fixedly connected to the main frame 2, and the square cover 4 is limitatively connected to the limit rod by a positioning mechanism. The U-shaped plate 9 is fixedly connected to the bottom plate 8, and both sides of the bottom plate 8 are provided with a rotating plate 7 rotatably connected to the bottom plate 8 through a hinge 15. Two opposing surfaces of the two rotating plates 7 are provided with two T-shaped slots 16, and a connecting baffle 6 is provided between the two opposite T-shaped slots 16. T-shaped slides 17 that are slidably connected to the corresponding T-shaped slots 16 are fixedly connected on both sides of the connecting baffle 6. A connecting rod 14 is provided below the other end of the main frame 2, and the connecting rod 14 is fixedly connected to the main frame 2 through a fixing rod 11. Both ends of the connecting rod 14 are rotatably connected to the moving wheels 10.

[0028] Preferably, the moving wheel 10 has a braking function, and the surface of the push handle 1 is covered with a rubber sleeve 3.

[0029] Preferably, one end of the main frame 2 is fixedly connected to a support column 12, one end of the support column 12 is fixedly connected to a support sheet 13, and the lower end surface of the support sheet 13 is fixedly connected to an anti-slip pad. The provision of the anti-slip pad can improve the anti-slip property of the support sheet 13.

[0030] Preferably, the connecting baffle 6, rotating plate 7 and bottom plate 8 are all made of bamboo, and the positioning mechanism includes a limiting cylinder 19 fixedly connected to one end of the rotating rod 18. By setting the connecting baffle 6, rotating plate 7 and bottom plate 8 to be made of bamboo, the ventilation performance of vegetables during storage can be improved, which is beneficial to keeping vegetables fresh.

[0031] Preferably, an abutment screw 20 is provided above the limiting cylinder 19, which passes through the square cover 4 and is threadedly connected to the penetrating portion. The abutment screw 20 is abutted and connected to the surface of the limiting cylinder 19. The setting of the abutment screw 20 can limit the limiting cylinder 19.

[0032] Preferably, one end of the abutting screw 20 is fixedly connected to a rotating head 5 , and the arrangement of the rotating head 5 facilitates manual rotation of the abutting screw 20 .

[0033] The specific working principle and usage of this utility model are as follows:

[0034] The utility model provides a multifunctional cart. When in use, the abutting screw 20 is rotated by rotating the rotating head 5, so that the abutting screw 20 is separated from the limiting cylinder 19, and the U-shaped plate 9 can be rotated by its own gravity under the action of the rotating rod 18 and the bearing, so that the U-shaped plate 9 can be kept in a vertical state. Then, vegetables and other items can be placed on the upper end of the bottom plate 8 in the U-shaped plate 9, and blocked by the rotating plate 7 and the connecting baffle 6, so that vegetables and other items can be stored for easy transportation. When the entire cart is moved to the position of setting up a stall, the entire cart can be placed flat on the ground and supported by the moving wheels 10 and the push handle 1. At this time, the universal wheels are locked to prevent the universal wheels from rolling. When the entire cart is placed flat on the ground, the U-shaped plate 9 remains perpendicular to the ground due to the action of the rotating rod 18 and the bearing. At this time, the rotating head 5 is rotated in the opposite direction to rotate the abutting screw 20, thereby moving the abutting screw 20 downward and making the abutting screw 20 abut and connect with the surface of the limiting cylinder 19, so that the limiting cylinder 19 is limited, thereby limiting the U-shaped plate 9 to prevent the U-shaped plate 9 from rotating. Then, by directly pulling the connecting baffles 6 on both sides of the bottom plate 8, the connecting baffles 6 drive the T-shaped slide plate 17 to separate from the T-shaped slide groove 16. After separation, the rotating plate 7 can be spread out by the action of the hinge 15, so that the entire cart can be transformed into a stall for the elderly to set up a stall, thereby improving the practicality of the cart.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
