Description

Technical Field

[0001] This utility model relates to the field of trolleys, specifically a new type of folding handcart base. Background Technology

[0002] As people's living standards improve, they often carry various items when traveling or shopping. However, backpacks generally have limited capacity and cannot meet the needs of travelers. To improve carrying capacity and accommodate more items, all kinds of handcarts have emerged.

[0003] The advent of handcarts has made it easier for users to carry items when out and about. Early handcarts did not have a folding function, so they could not be folded after use, taking up a lot of storage space and making them inconvenient to store. Then, a large number of folding handcarts emerged, which not only met users' needs for moving items, but also made it easier to store the handcarts after use. Therefore, folding handcarts are highly favored for outdoor activities due to their portability, durability, and ease of storage.

[0004] Currently, the base of folding handcarts is foldable, and most of them have a cross structure. Their load-bearing capacity and ability to carry items are limited. It is necessary to set U-shaped support structures on both sides of the folding cart to support the base. In order to enhance the load-bearing capacity of the folding cart, some bases are set as two rotating connected parts. However, the folded bases are all left idle and cannot be reused. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a novel folding handcart base plate with a novel design, multiple functions, and strong load-bearing capacity. It can stably carry essential outdoor products without the need for a support structure to lift the base plate. Moreover, after folding, the top can form a flat structure that can be reused by the user, achieving the effect of making the most of the material.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model includes a horizontally arranged connector and brackets rotatably connected to the connector and symmetrically arranged on both sides of the connector. The connector is U-shaped, and the connection end of the connector and the bracket is located in the U-shaped groove of the connector. One end of the bracket is rotatably connected to a fulcrum located at both ends of the connector, and the other end of the bracket is rotatably connected to the vehicle body. When the bracket rotates to a vertical position, it lifts the U-shaped groove of the connector. When the bracket rotates around the fulcrum to a vertical position, it supports the connector into a right prism with a flat top surface and rectangular sides. The bracket includes a crossbar connected to the fulcrum, a connecting rod disposed between the two crossbars, and a support rod disposed between the two connecting rods. The fulcrum includes a first fulcrum and a second fulcrum. The crossbar includes a first crossbar rotatably connected to the connector through the first fulcrum and a second crossbar rotatably connected to the connector through the second fulcrum. The other ends of the first crossbar and the second crossbar are both rotatably connected to the vehicle body.

[0008] A further improvement of this utility model is that a pivot is provided at the connection between the first fulcrum and the first crossbar, and at the connection between the second fulcrum and the second crossbar.

[0009] A further improvement of this utility model is that: the first crossbar and the second crossbar rotate from a horizontal state to a vertical state along the pivot axis to lift the joint horizontally, and the top surfaces of the two joints are on the same plane.

[0010] The beneficial effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0011] This utility model features a novel design and a reasonable structure. It not only fulfills the function of a handcart to carry heavy objects, but also allows the folded handcart, along with its base plate, to form a rectangular table or stool with a flat top, making it convenient for outdoor users. The base plate, when folded, forms a structure with a flat top, which can be used to place items or for users to sit on. Moreover, the height of the folded handcart is the same as the height of the folded base plate, so the requirements for height space during storage are not high, achieving the effect of making the most of the material.

[0018] The present invention will be further described in detail below with reference to embodiments:

[0019] The base of a new type of folding handcart, such as Figure 1-3 As shown, it includes a horizontally positioned connector 3 and brackets rotatably connected to the connector 3 and symmetrically arranged on both sides of the connector 3. One end of each bracket is rotatably connected to a fulcrum located at both ends of the connector 3. When the brackets rotate around the fulcrum to a vertical position, they support the connector 3 into a right prism with a flat top surface and rectangular sides. After folding, the two connectors 3 are supported by the brackets as follows: Figure 2 and Figure 3 As shown, placing a flat plate between the joints 3 forms a table or stool with the support as the legs and the flat plate as the tabletop or seat, which is convenient for users and makes the best use of the materials.

[0020] One end of the bracket is rotatably connected to connector 3, and the other end of the bracket is rotatably connected to the vehicle body. When the height of the vehicle body is the same as the length of the bracket, the height of the folded trolley is the same as the height of the folded base plate, forming a cuboid structure with a flat top and rectangular sides. Figure 4 and Figure 5 As shown, it meets the diverse needs of outdoor users.

[0021] like Figure 1-3 As shown, the connector 3 is U-shaped, and the connection end of the connector 3 to the bracket is located in the U-shaped groove of the connector 3. When the bracket is rotated to a vertical position, it lifts up the U-shaped groove, forming a rectangular table or stool structure with the connector 3 as the top surface and the bracket as the legs. A flat plate is placed on the top surface, meeting various needs of outdoor users: enjoying food; playing chess, cards, and other forms of entertainment; and providing a place for users to sit and rest. When unfolded, it can carry and transport items such as... Figure 1 As shown, it can also be used as a table or stool after folding. Figure 2 and Figure 3 As shown, this truly makes the best use of resources and is well-liked by users.

[0022] like Figure 1 and Figure 2As shown, the bracket includes a crossbar 1-3 connected to the fulcrum, a connecting rod 1-1 disposed between two crossbars 1-3, and a support rod 1-2 disposed between two connecting rods 1-1. The crossbars 1-3, connecting rods 1-1, and support rods 1-2 facilitate the bearing of heavy objects. To meet the needs of bearing heavy objects, the number of support rods 1-2 can be increased, or more than one support rod 1-2 can be added between the two joints 3 to increase its load-bearing capacity. It is evident that the base plate is sturdy and durable, has good load-bearing capacity, and can reliably bear heavy objects without the support of a pallet.

[0023] The fulcrum includes a first fulcrum 3-1 and a second fulcrum 3-2. The crossbar 1-3 includes a first crossbar 1 and a second crossbar 2. The first crossbar 1 is rotatably connected to the first fulcrum 3-2, and the second crossbar 2 is rotatably connected to the second fulcrum 3-2. A pivot is provided at the connection points of the first fulcrum 3-1 and the first crossbar 1, and at the connection points of the second fulcrum 3-2 and the second crossbar 2. Figure 1 The unfolded base plate shown can carry and transport a variety of items. After transporting, the first crossbar 1 and the second crossbar 2 are simultaneously rotated downwards, causing the first crossbar 1 and the second crossbar 2 to... Figure 1 When the horizontal state is turned into the vertical state, such as Figure 2 and Figure 3 As shown, stop rotating to complete the folding.

[0024] The other ends of the first crossbar 1 and the second crossbar 2 are rotatably connected to the vehicle body. At this time, the first crossbar 1 and the second crossbar 2 simultaneously drive the vehicle body to move inward, completing the folding process. Figure 4 and Figure 5 The folding bike is in its folding state.

[0025] like Figure 2 and Figure 3 As shown, the first crossbar 1 and the second crossbar 2 rotate from a horizontal state to a vertical state along the fulcrum to lift the joint 3 horizontally. The top surfaces of the two joints 3 are on the same plane. A flat plate is placed on the joint 3, thus forming a rectangular table or stool with the first crossbar 1 and the second crossbar 2 as legs and the flat plate on the top of the joint 3 as a tabletop or stool surface for outdoor users.

[0026] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are by no means intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description; it is impossible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom still fall within the protection scope of this invention.
