Description

Foldable utility vehicle

technical field

The utility model belongs to the technical field of transport tools, in particular to a foldable multifunctional transport vehicle.

Background technique

Nowadays, transport vehicles have been popularized in hypermarkets, flower and bird markets and other places. Whether shopping in supermarkets or carrying flowers, heavy objects, chemical products, etc., transport vehicles are required. However, most of these transport vehicles have single functions and are basically composed of a basket, wheels and handles. The main shortcomings are as follows: 1. The basket is made of stainless steel grid structure, and chemical products will be corroded during secondary handling , and it is difficult to clean because it cannot be disassembled; 2. It can only transport ordinary goods, which is extremely troublesome when transporting large objects, especially when transporting flowers and other items, the frame of the traditional basket is too high, and it is easy to damage the hanging branches and leaves of flowers; 3. The general transport vehicle has only one basket, and the number of transported items is limited, which cannot meet the needs of consumers; 4. The wheels commonly used in transport vehicles are rollers, which are light in weight, poor in adaptability to the road surface and easy to shake, which is not conducive to dangerous goods and precious goods. Shipping of Items.

In the prior art, a kind of "supermarket shopping cart with double-layer loading net bag" as disclosed by the Chinese utility model patent authorization announcement number CN201405897Y includes a car body frame composed of a bottom frame and a vertical rod frame, wheels, and bottom loads. The net bag also includes a top load net bag. The vertical bar frame is mainly composed of four symmetrical vertical bars on the left and right, two upper and lower transverse tension fixing bars, a support fixing bar and a horizontal push handle rod. The top load net bag is arranged on Stands on a vertical pole and folds away. Compared with traditional transport carts, this kind of shopping cart has been greatly improved, but there are still many shortcomings: first, the upper and lower net pockets are non-detachable structures, which increases the difficulty of cleaning; The rectangular frame is flipped and connected, the connection strength between the two is not enough, the rectangular frame is easy to break and affects the service life; third, the top-loaded net bag has no base to lift it, and it is directly erected on the vertical pole frame, which is easy to deform the top-loaded net bag and cause it to fail. fold.

For another example, a "flower and tree transport vehicle" introduced by the Chinese utility model patent authorization announcement number CN2883240Y includes a base plate and at least three side plates, and is characterized in that the base plate is connected to one of the three side plates through a pivot , the bottom plate can rotate around the pivot. The side plate connected with the bottom plate is rotatably connected with at least one of the other two side plates through a pivot. Because the utility model can make the whole transport vehicle foldable by setting between the base plate and the side plate, and between the side plate and the side plate to make the pivot relatively rotatable between the two, and occupy a relatively small volume, like this After sending the flowers and trees, the transport vehicle can be transported back with relatively little transportation cost, achieving the purpose of recycling and cost saving. The shortcoming of this transport vehicle is: its structural strength is poor, the space that places flowers and trees is limited, is not suitable for transporting larger potted flowers and trees;

In view of the above-mentioned prior art, it is necessary to improve the structure of the existing transport vehicle. For this reason, the applicant has made active and effective explorations, and has finally formed the technical scheme to be introduced below.
