Description

Technical Field

[0001] This invention relates to the field of warehousing equipment, and in particular to a handling trolley with a folding and storage structure. Background Technology

[0002] Warehouse handling trolleys are tools used to move goods and items. They can be used in warehouses, factories, and other logistics environments. Their main functions are to improve work efficiency, reduce manual labor, and reduce risks during the handling process.

[0003] Handling trolleys can be divided into two types: manual and electric. Manual handling trolleys mainly rely on human power to push, while electric handling trolleys are driven by electricity. Depending on different needs, warehouse handling trolleys can be divided into various types, such as flatbed trucks, forklifts, and stackers. When selecting a handling trolley, it is necessary to choose the appropriate style and specifications based on actual needs and scenarios.

[0004] Existing handling trolleys take up a lot of floor space when not in use in the warehouse, and can only be used on the ground floor. The space above the ground cannot be used well, resulting in a waste of space. Summary of the Invention

[0005] The main technical problem solved by this invention is to provide a transport trolley with a folding and storage structure, which can improve the utilization rate of storage space.

[0006] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is: to provide a transport trolley with a folding and storage structure, including a base plate and four guide wheels, wherein the four guide wheels are respectively connected to the base plate, and the folding and storage structure is installed on the base plate;

[0007] The folding storage structure includes a folding arm structure for folding and a stacking structure for storage, and the four guide wheels are mounted on the folding arm structure via brackets.

[0008] In a preferred embodiment of the present invention, the folding arm structure includes four horizontal bars and four vertical bars. The four horizontal bars and the four vertical bars are connected by a first rotating structure. The four horizontal bars are connected to the base plate by a second rotating structure. The second rotating structure is installed in a first slot on the base plate.

[0009] In a preferred embodiment of the present invention, the four guide wheels are installed at the bottom of the first rotating structure and are collinear with the vertical rod. The bottom of the horizontal rod is provided with a groove, which cooperates with the guide wheels.

[0010] In a preferred embodiment of the present invention, the stacking structure includes four splicing plates, which are respectively installed on the top of the four vertical rods, and the splicing plates are vertically fixedly connected to the vertical rods.

[0011] In a preferred embodiment of the present invention, a handle is also installed on the base plate. The handle is connected to the base plate via a pull rod, and the pull rod is installed in a second slot on the base plate via a third rotating structure.

[0012] In a preferred embodiment of the present invention, the first rotating structure, the second rotating structure and the third rotating structure are each composed of a circular hole and a rotating shaft. The circular hole is opened at the rotating end of the two rotating connections, and the rotating shaft is opened at the fixed end of the two rotating connections.

[0013] In a preferred embodiment of the present invention, a first anti-slip layer is provided at the bottom of the rotating shaft and at the bottom and 90° right side of the circular hole in both the first rotating structure and the second rotating structure.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0023] Please see Figures 1 to 5 The embodiments of the present invention include:

[0024] A transport trolley with a folding and storage structure includes a base plate 1 and four guide wheels 2. The four guide wheels 2 are respectively connected to the base plate 1. The folding and storage structure is installed on the base plate 1, so that the entire trolley can be folded up and stacked when stored, thereby improving the utilization rate of storage space.

[0025] The folding storage structure includes a folding arm structure for folding and a stacking structure for storage, and the four guide wheels 2 are mounted on the folding arm structure by a bracket.

[0026] The folding arm structure includes four horizontal rods 3 and four vertical rods 4. The four horizontal rods 3 and the four vertical rods 4 are connected by a first rotating structure 5. The four horizontal rods 3 are connected to the base plate 1 by a second rotating structure 6. The second rotating structure 6 is installed in a first slot 12 on the base plate 1. The first rotating structure 5 and the second rotating structure 6 cooperate to allow the folding storage mechanism to be opened and closed.

[0027] The guide wheel 2 is installed at the bottom of the first rotating structure 5 and is collinear with the vertical rod 4. The guide wheel 2 is a caster wheel and is used to move the trolley when it is opened.

[0028] The bottom of the horizontal rod 3 is provided with a groove 8, which cooperates with the guide wheel 2 so that when storing, the guide wheel 2 can be inserted into the groove 8 after rotating by an angle, making it convenient to store.

[0029] The stacking structure includes four splicing plates 9, which are respectively installed on the top of the four vertical rods 4. The splicing plates 9 are vertically fixed to the vertical rods 4. The size and shape of the four splicing plates 9 after combination are the same as the base plate 1, so that the transport trolley can be stacked after storage, thereby improving the utilization rate of storage space.

[0030] A handle 10 is also installed on the base plate 1. The handle 10 is connected to the base plate 1 via a pull rod 11. The pull rod 11 is installed in the second slot 13 on the base plate 1 via a third rotating structure 7. The handle 10 is used to move the trolley by human or external object after it is opened.

[0031] The first rotating structure 5, the second rotating structure 6, and the third rotating structure 7 are all composed of a circular hole and a rotating shaft. The circular hole is opened at the rotating end of the two rotating connections, and the rotating shaft is opened at the fixed end of the two rotating connections.

[0032] In both the first rotating structure 5 and the second rotating structure 6, a first anti-slip layer 14 is provided at the bottom of the rotating shaft and at the bottom and 90° position on the right side of the circular hole. The first anti-slip layers 14 cooperate with each other to limit the opening and closing of the horizontal rod 3 and the vertical rod 4. When opened, the first anti-slip layer 14 at the bottom of the rotating shaft in both the first rotating structure 5 and the second rotating structure 6 cooperates with the first anti-slip layer 14 at the 90° position on the right side of the corresponding circular hole to limit the opening. When closed, the first anti-slip layer 14 at the bottom of the rotating shaft in both the first rotating structure 5 and the second rotating structure 6 cooperates with the first anti-slip layer 14 at the bottom of the corresponding circular hole to limit the opening.

[0033] In the third rotating structure 7, the bottom of the rotating shaft and the bottom of the circular hole are both provided with a second anti-slip layer 15. The second anti-slip layer 15 cooperate with each other to limit the position of the pull rod 11 perpendicular to the base plate 1 when it is stored. Since the user's height is different, the angle can be changed at will and is not restricted.

[0034] Unlike existing technologies, this invention provides a transport trolley with a folding storage structure. The folding storage structure allows the entire trolley to be folded up and stacked during storage, thereby improving the utilization rate of storage space.
