Description

Technical Field

[0001] This utility model relates to the field of transportation vehicle technology, specifically a dual-structure multi-purpose folding vehicle. Background Technology

[0002] A handcart is a lightweight, human-powered transport tool used for short-distance goods movement. Its core design features an open cargo box or platform structure, coupled with wheels and a handle, making it suitable for various scenarios including home, industry, and commerce. Used to carry goods, they come in various shapes and sizes, typically with 1-4 wheels made of rubber, pneumatic tires, or solid tires to adapt to different surfaces such as concrete and mud. They require no fuel or electricity and move by pushing or pulling. The handcart's core advantages are its human-powered operation and flexibility, making it a classic tool for short-distance transport.

[0003] In existing technologies, such as the handcart disclosed in publication number CN215826724U, a support frame and a roller assembly are included. The support frame includes a support portion and an item placement rack, which is disposed on the support portion. At least a portion of the item placement rack along one side in a first direction has a flat surface. The roller assembly includes a connecting rod and rollers, with the rollers rotatably connected to the connecting rod. The connecting rod is connected to the support frame via a connector. By making at least a portion of the item placement rack along one side in the first direction flat, the existing structure of the item placement rack is changed. This eliminates the need to weld multiple steel pipes side-by-side at intervals, thus saving the alignment work required when welding multiple steel pipes in practical applications and solving the technical problem of low efficiency in the production and processing of existing handcarts.

[0004] The existing handcart changes the structure of the existing item placement rack by making at least part of one side of the item placement rack flat along the first direction, so that it does not need to be welded together by multiple steel pipes at intervals. In practical applications, it saves the alignment work when welding multiple steel pipes. However, it cannot be adjusted according to the handling needs of different items at the work site, so it is necessary to change the handcart when handling different items, which makes it less practical.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Example 1:

[0031] Please see Figures 1-5 This is the first embodiment of the present invention.

[0032] This embodiment provides a dual-structure multi-purpose folding cart, including a cart frame 1, with cart wheels 2 rotatably connected to both ends of the cart frame 1. One side of the cart frame 1 is provided with an adjustment mechanism for adjusting the cart, and the lower end of the adjustment mechanism is provided with a push-pull mechanism for assisting in pushing and pulling. One side of the push-pull mechanism is provided with a limiting mechanism for limiting the position.

[0033] The adjustment mechanism includes a fixed frame 3, which is fixed to one side of the trolley frame 1. A reinforcing plate 31 is welded to the inner wall of the fixed frame 3. Two fixed plates 32 are welded to the fixed frame 3 on one side of the reinforcing plate 31. Hinges 33 are connected to the side walls of the two fixed plates 32.

[0034] Specifically, the hinge 33 has a fixed bearing 34 embedded inside, which is rotatably connected to the fixed plate 32 via a pivot.

[0035] Furthermore, since the fixed bearing 34 is fixed to the fixed plate 32 through a rotating shaft, the hinge 33 can rotate, ensuring the normal rotation of the hinge rod 35.

[0036] Specifically, a hinge rod 35 is hinged to the outer surface of the hinge member 33.

[0037] Furthermore, the hinge rod 35 is hinged to the mounting plate 4, so that when the mounting plate 4 is driven to move horizontally, the hinge rod 35 is driven to rotate to the horizontal direction, and the hinge 33 needs to be rotated to the horizontal direction so that the trolley frame 1 and the hinge 33 cooperate to form a flatbed trolley, thereby facilitating the transportation of different items.

[0038] In use, first move the trolley frame 1 to a suitable position. Using the trolley wheels 2 on the trolley frame 1, you can manually move the trolley frame 1 by supporting the handle at the end of the fixing frame 3. Place the items to be transported onto the trolley frame 1 for transport. The fixing frame 3 is equipped with a reinforcing plate 31, which, in conjunction with the fixing plate 32, enhances the overall strength of the fixing frame 3, thereby improving the load-bearing capacity of the folding cart. When transporting different items, pull the movable frame 43 horizontally. With the cooperation of the hinge 33, and because the fixed bearing 34 is fixed to the fixing plate 32 via a rotating shaft, the hinge 33 can rotate, ensuring the normal rotation of the hinge rod 35. The hinge rod 35 is hinged to the mounting plate 4. When the mounting plate 4 is moved horizontally, the hinge rod 35 is rotated to the horizontal direction, and the hinge 33 needs to be rotated to the horizontal direction as well. This allows the trolley frame 1 and the hinge 33 to cooperate to form a flatbed cart, facilitating the transport of different items.

[0039] In summary, when this dual-structure multi-purpose folding cart is in use, it is fixed to the fixed plate 32 via a rotating shaft inside the fixed bearing 34, ensuring the normal rotation of the hinge rod 35. When the mounting plate 4 is driven to move horizontally, the hinge rod 35 is driven to rotate to the horizontal direction, and the hinge 33 also needs to be rotated to the horizontal direction, so that the cart frame 1 and the hinge 33 cooperate to form a flatbed cart, thereby facilitating the transport of different items.

[0040] Example 2:

[0041] Please see Figures 1-5 This is the second embodiment of the present utility model.

[0042] Specifically, the push-pull mechanism includes a mounting plate 4, which is hinged to the end of the hinge rod 35. A fixing rod 41 is welded to one side of the mounting plate 4, and a caster wheel 42 is fixed to the lower surface of the mounting plate 4 by screws.

[0043] Furthermore, the fixed rod 41 installed on the mounting plate 4, in conjunction with the casters 42, ensures the normal movement of the flatbed truck.

[0044] Specifically, a movable frame 43 is welded to the upper surface of the mounting plate 4, and a reinforcing rod 44 is welded to one side of the movable frame 43.

[0045] Furthermore, the strength of the movable frame 43 can be enhanced by reinforcing rod 44, thereby increasing its service life.

[0046] Specifically, the limiting mechanism includes two limiting components 5, both of which are installed on the outside of the movable frame 43 and welded to the reinforcing plate 31.

[0047] Furthermore, the limiting component 5 can limit the movable frame 43, effectively reducing the possibility of the movable frame 43 opening accidentally.

[0048] Specifically, the side walls of the two limiting members 5 are each equipped with fixing bolts 51, and the ends of the fixing bolts 51 are inserted into the limiting holes 52 opened on the movable frame 43.

[0049] Furthermore, the fixing bolt 51 on the limiting member 5 is unscrewed, so that the end of the fixing bolt 51 is separated from the limiting hole 52, thereby releasing the limitation on the movable frame 43.

[0050] In use, the fixing bolt 51 on the limiting member 5 is unscrewed, causing the end of the fixing bolt 51 to separate from the limiting hole 52, thereby releasing the limitation on the movable frame 43. Furthermore, the fixed rod 41 on the mounting plate 4, in conjunction with the casters 42, ensures the normal movement of the flatbed cart. Goods can be transported by pushing and pulling the movable frame 43. The reinforcing rod 44 enhances the strength of the movable frame 43 and improves its service life.

[0051] In summary, when in use, this dual-structure multi-purpose folding cart is fixed to the fixed plate 32 via a rotating shaft inside the fixed bearing 34, ensuring the normal rotation of the hinge rod 35. When the mounting plate 4 is driven to move horizontally, the hinge rod 35 is driven to rotate to the horizontal direction, and the hinge 33 also needs to be rotated to the horizontal direction, so that the cart frame 1 and the hinge 33 cooperate to form a flatbed cart, thus facilitating the transport of different items. Furthermore, the fixed rod 41 provided on the mounting plate 4, in cooperation with the casters 42, ensures the normal movement of the flatbed cart.
