[0046] Please refer to Figures 1 to 9 The present application provides a scalable and tilting cart, which comprises a chassis 1, universal wheels 2 and a push-pull assembly 3, and has a simple structure.

[0047] As shown in Figure 1 and Figure 8 The chassis 1 comprises a support frame 11 and a first bearing part 12 and a second bearing part 13 connected to the support frame 11. The upper surface of the first bearing part 12 is horizontally arranged. The upper surface of the second bearing part 13 is arranged obliquely, and the upper surface of the second bearing part 13 gradually inclines upward in the direction away from the first bearing part 12, so that the transported objects are inclined to the push-pull assembly 3 arranged on the side of the second bearing part 13 close to the first bearing part 12, avoiding the outward dumping of the transported objects during transportation. The support frame 11 is provided with a first connecting part 14 on the side of the first bearing part 12 away from the second bearing part 13, and a second connecting part 15 between the first bearing part 12 and the second bearing part 13. The first connecting part 14 and the second connecting part 15 are both used for connecting with the push-pull assembly 3. A plurality of universal wheels 2 are connected below the chassis 1, which can control the running direction of the cart.

[0048] The push-pull assembly 3 is connected above the chassis 1. The push-pull assembly 3 comprises a first frame 31 and a second frame 32. As shown in Figure 1 and Figure 8 , the second frame 32 is telescopically connected to the first frame 31, and the length of the second frame 32 extending out of the first frame 31 can be adjusted as needed, so that the height of the push-pull assembly 3 can be adjusted to adapt to different heights of the transported objects, thereby expanding the application range of the stroller.

[0049] The first frame 31 is rotatably connected to the first connecting portion 14, and the first frame 31 is detachably connected to the first connecting portion 14 or the second connecting portion 15, so that the stroller has different unfolded states. The stroller has a folded state, a first unfolded state, and a second unfolded state.

[0050] As shown in Figures 5 to 7 , when the stroller is in the folded state, the push-pull assembly 3 is parallel to the support frame 11, the second frame 32 is telescopically connected to the first frame 31, and the first frame 31 is connected to the first connecting portion 14.

[0051] As shown in Figures 1 to 4 , when the stroller is in the first unfolded state, the push-pull assembly 3 forms an obtuse angle with the support frame 11, which can ensure the smoothness and safety of transportation, and the transported objects are inclined to the push-pull assembly 3, thereby avoiding the outward dumping of the transported objects during transportation. The bottom of the first frame 31 is connected to the first connecting portion 14, and the transported objects can be placed on the first carrying portion 12 or on the first carrying portion 12 and the second carrying portion 13, thereby improving the utilization rate of the chassis 1.

[0052] As shown in Figure 8 and Figure 9 , when the stroller is in the second unfolded state, the push-pull assembly 3 forms an obtuse angle with the support frame 11, which can also ensure the smoothness and safety of transportation. For the angle between the push-pull assembly 3 and the support frame 11, the angle in the second unfolded state is greater than the angle in the first unfolded state. The bottom of the first frame 31 is connected to the second connecting portion 15, so that the transported objects can be placed on the second carrying portion 13. In this state, the second frame 32 is extended out of the first frame 31, which can make the stroller suitable for transporting larger (higher) transported objects.

[0053] In summary, according to the specifications and quantities of the transported objects, the unfolded state of the stroller and the telescopic state of the second frame 32 can be selected, thereby improving the transportation efficiency.

[0054] In the embodiment, the second bearing part 13 comprises a plurality of inclined rods 131 arranged in the first horizontal direction X, one end of the inclined rods 131 is fixedly connected with the support frame 11 in the second horizontal direction Y, and the other end is fixedly connected with the first bearing part 12. The end of the inclined rods 131 connected with the first bearing part 12 has a part higher than the top surface of the first bearing part 12, which is used for limiting the transported objects on the first bearing part 12 or for limiting the push-pull assembly 3 in the second unfolded state. The second horizontal direction Y is perpendicular to the first horizontal direction X, and both are perpendicular to the vertical direction.

[0055] As shown in Figure 1 , the first bearing part 12 comprises a first rod body 121 extending in the first horizontal direction X and a plurality of second rod bodies 122 extending in the second horizontal direction Y.

When the stroller needs to be transformed between the folded state and the first unfolded state, the pin shaft 311 can be retracted, adjusted to the appropriate position (the first pin hole 142 or the second pin hole 143), and then the pin shaft 311 is extended.

[0059] In the embodiment, the top surface of the first bearing part 12 is lower than the top surface of the support frame 11, and the second connecting part 15 comprises a third pin hole 151 arranged on the inner side wall of the support frame 11 and above the first rod body 121. When the stroller is in the second unfolded state, the pin shaft 311 is arranged in the third pin hole 151, and the bottom of the first frame body 31 abuts against the part of the inclined rod 131 which is higher than the top surface of the first bearing part 12. When the stroller needs to be adjusted to the second unfolded state, the pin shaft 311 can be retracted, and then the pin shaft 311 is extended after being adjusted to the third pin hole 151.

[0060] Specifically, as shown in Figure 3 , two first connecting plates 141 are arranged on the two opposite sides of the support frame 11 in the first horizontal direction X. The support frame 11 is fixedly provided with two second connecting plates 4 on the side away from the second bearing part 13.
