[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] The existing flatbed carts cannot fold the wheels, which results in a larger overall height, a waste of storage space, and low practicality. Please refer to Figure 1-Figure 5This embodiment provides a new type of foldable flatbed cart, the wheels of which can be folded to facilitate the stacking and storage of the flatbed cart. The flatbed cart includes a support plate 1 for placing items, moving wheels 2 arranged around the bottom of the support plate 1, and a pull rod 6 movably arranged on one side of the support plate 1. The support plate 1 is provided with a support seat 3 for supporting the moving wheels 2 after they are folded and stored. The support plate 1 is provided with a folding mechanism 5 for folding the moving wheels 2. The folding mechanism 5 includes a reset component 53 for folding the moving wheels 2 to one side and a baffle 50 for preventing the moving wheels 2 from tilting outward. The reset component 53 is provided with a top plate 51 for blocking the moving wheels 2. The top plate 51 is provided with a card slot 52, and the reset component 53 is provided with a limiting component 54 that cooperates with the card slot 52. The reset component 53 can block or disengage the moving wheels 2. The moving wheel 2 is arranged to rotate inside the supporting flat plate 1, and the moving wheel 2 can be smoothly folded into the supporting flat plate 1. At this time, under the action of the reset component 53, the bottom of the moving wheel 2 will be blocked, so that the moving wheel 2 will not fall, achieving a better folding effect. At the same time, a support seat 3 is provided at the bottom of the supporting flat plate 1. After the moving wheel 2 is folded, the support seat 3 will support the supporting flat plate 1 for easy stacking. When the moving wheel 2 is not folded, the reset component 53 and the baffle 50 will block the two sides of the moving wheel 2, so that the moving wheel 2 can smoothly drive the movement of the supporting flat plate 1, and by pulling or pushing the pull rod 6, the overall movement effect of the supporting flat plate 1 is achieved.

[0024] The reset component 53 solves the problem that the top plate 51 can slide and reset during the folding of the moving wheel 2, so that the moving wheel 2 can be folded smoothly. The limiting component 54 is mainly used to limit the top plate 51 to ensure that the moving wheel 2 does not tilt inward during the movement. In use, the reset component 53 includes a mounting block 530 fixed to the supporting plate 1, a sliding groove 531 is provided on the mounting block 530, a sliding rod 532 is provided inside the sliding groove 531, and a sliding rod 532 is sleeved on the sliding rod 532. The plate 534 is provided with a spring 533 between the slide plate 534 and the slide groove 531, and the limiting component 54 includes a limiting card plate 540 provided on the mounting block 530. The limiting card plate 540 is provided with a limiting groove 541. The mounting block 530 is provided with a limiting card block 542 to prevent the limiting component 54 from falling. The limiting card block 542 is in the shape of a T-shaped block. Through the provided card slot 52, the hand can push the limiting card plate 540 upward through the card slot 52. The provided limiting card plate 540 is in the limit card The top plate 51 is then pulled to drive the slide plate 534 to slide along the slide bar 532, thereby compressing the spring 533. At this time, the moving wheel 2 will not be blocked, and the moving wheel 2 can be rotated to the inside of the supporting plate 1 for folding. The top plate 51 is then released. Under the action of the spring 533, the top plate 51 is driven to block the moving wheel 2 to prevent the moving wheel 2 from falling out, thereby achieving a better folding and storage effect. At the same time, the top plate 51 can be pulled to release the moving wheel 2. At this time, the top plate 51 is released. Under the action of the spring 533, the top plate 51 will be driven to move in the direction of the moving wheel 2. When the top plate 51 just contacts the moving wheel 2, the slot 52 set on the top plate 51 just exceeds the limit card plate 540. At this time, the limit card plate 540 will move downward along the limit card block 542 under the influence of gravity and pass through the slot 52. At this time, the top plate 51 set will not be able to move. In conjunction with the baffle 50 set, the two sides of the moving wheel 2 can be blocked to ensure that the moving wheel 2 will not tilt during the movement of the supporting plate 1.

[0025] Example 2

[0026] Based on Example 1, Figure 1-Figure 5As shown, based on the current problem that after the flatbed wheels are successfully folded, the pull rod of the flatbed cannot be folded and stored, and there is still a problem that affects the placement and storage effect of the flatbed. Therefore, the device is also provided with a connecting plate 43 for maintaining the rotation of the pull rod 6 and a placement plate 41 for placing the pull rod 6. The interior of the supporting flat plate 1 is provided with a fixing component 42 for storing the pull rod 6. The fixing component 42 includes a fixing plate 420 arranged inside the supporting flat plate 1 for installing the moving wheel 2 and the mounting block 530, the fixing plate 420 is provided with a Velcro sub-strap 421 for fixing the pull rod 6, and a Velcro mother tape 422 used in conjunction with the Velcro sub-strap 421, the fixing plate 420 is provided with a support block 423 for supporting the pull rod 6 located between the Velcro sub-strap 421 and the Velcro mother tape 422, and the length of the support block 423 is consistent with the width of the middle part of the pull rod 6, and the length inside the placement plate 41 and the length inside the connecting plate 43 are both greater than the width of the two end parts of the pull rod 6.

[0027] The specific implementation process of this embodiment is as follows: by rotating the pull rod 6 clockwise, the upper end of the pull rod 6 is located inside the placement plate 41, and the lower end is located inside the connecting plate 43. At the same time, the two ends of the middle part will contact the support block 423, and then the Velcro sub-band 421 is pulled upward, and the Velcro sub-band 421 is attached to the pull rod 6. Then the Velcro mother tape 422 is pulled upward, and the Velcro mother tape 422 is attached to the Velcro sub-band 421. The set Velcro sub-band 421 and Velcro mother tape 422 will adhere together to fix the pull rod 6. The length of the set support block 423 is consistent with the middle part of the pull rod 6, which ensures that there is no space for the pull rod 6 to move left and right after fixation, thereby achieving a better folding and storage effect of the pull rod 6 and higher practicality.
