Description

Technical Field

[0001] The utility model relates to the field of transportation equipment, in particular to a lightweight transportation vehicle base which is convenient for stacking. Background Art

[0002] With the rapid development of economy, the demand for large LED display screens is increasing in the market, and they are gradually shining in industries such as advertising, stage background and rental. For example, large-scale commercial performances use large LED display screens to build dynamic and gorgeous stage backgrounds, creating a unique stage art effect.

[0003] In order to facilitate transportation and installation, large LED display screens are usually assembled from several groups of LED display screen cabinets. However, the traditional transportation method is to load the LED display screen cabinet directly onto a truck and fix it with ropes, or to place the LED display screen cabinet on a transport bracket and then fix it with ropes. These two transportation methods not only have low loading and unloading efficiency, but also are prone to collision and extrusion between LED display screen cabinets during transportation, causing damage. In addition, some LED display screen cabinets are also transported in air box packaging, but this transportation method is expensive. Later, a transport vehicle for LED display screen cabinets appeared, which improved the disassembly and assembly efficiency of the display screen by improving the cart; however, the existing transport vehicle for display screen cabinets still has shortcomings. Specifically, the base of the existing transport vehicle is usually a load-bearing bottom plate, and reinforcing ribs are arranged under the load-bearing bottom plate (such as Chinese patent CN214929861U). This structure is not only expensive to produce and heavy, but also cannot be stacked for transportation and storage, which increases transportation and warehouse costs.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
