Description

Technical Field

[0001] The utility model relates to the field of transportation equipment, in particular to a display screen box device transportation vehicle. 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 vehicles for display screen cabinets still have shortcomings. When these transport vehicles are idle, they take up a large space and cannot be well stacked and stored, which takes up a lot of space; at the same time, the existing carts of this type are not clever enough in design, resulting in a large space being occupied during the sales and transportation process, which increases the transportation cost.

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

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] See attached Figures 1 to 10 In an embodiment of the utility model, a display screen box device transport vehicle includes a vehicle body 100, the vehicle body 100 includes a base 10, a first side door 20 arranged on the left side of the base 10, and a second side door 30 arranged on the right side of the base 10, the base 10 is provided with a first fixing structure for fixing the lower side of the display screen; the first side door 20 and the second side door 30 are provided with a second fixing structure for fixing the upper side of the display screen;

[0036] A plurality of universal wheels 11 are installed below the base 10, and the base 10 is provided with a positioning cavity 12 for accommodating the universal wheels 11, and the positioning cavity 12 has an opening, and the opening is arranged toward the top of the base 10;

[0037] Furthermore, the first side door 20 and the second side door 30 are detachably mounted on the base 10; the first fixing structure and the second fixing structure are provided in a plurality along the front-rear direction. Thus, through the specific configuration of the transport vehicle, a transport vehicle can fix and transport multiple display screens, and the base 10 of the transport vehicle can also be stacked for storage and transportation; the transportation cost and storage space can be effectively saved. The universal wheels 11 are usually four arranged at four corners.

[0038] The first side door 20 and the second side door 30 are quickly assembled and disassembled on the base 10 by means of buckles. Furthermore, the base 10 is rectangular, and a first positioning structure is provided on the left end face of the base 10, and a second positioning structure corresponding to the first positioning structure is provided on the right end face of the base 10. Specifically, the first positioning structure and the second positioning structure both include a positioning boss 13 and a positioning circular hole 14 adapted to the positioning boss 13; the positioning boss 13 is a truncated cone, and the diameter of the lower bottom surface of the positioning boss 13 is smaller than the diameter of the positioning circular hole 14. During positioning, the positioning boss 13 is located in the positioning circular hole 14, and a fine-tuning gap is maintained between the positioning boss 13 and the positioning circular hole 14.

[0039] In this way, when there are multiple transport vehicles, the transport vehicles adjacent to each other on the left and right can be connected and positioned by the first positioning structure and the second positioning structure. For example, when there are three transport vehicles arranged on the left and right, they are defined as: the first transport vehicle, the second transport vehicle, and the third transport vehicle. When storing or transporting: the first positioning structure on the left end face of the second transport vehicle and the second positioning structure on the right end face of the first transport vehicle are positioned with each other; the second positioning structure on the right end face of the second transport vehicle and the first positioning structure on the left end face of the third transport vehicle are positioned with each other. When positioning, the positioning boss 13 of the first positioning structure is inserted into the positioning circular hole 14 of the second positioning structure, and the positioning boss 13 of the second positioning structure is also inserted into the positioning circular hole 14 of the first positioning structure; and, due to the setting of the aforementioned fine-tuning gap, the transport vehicles (groups) can be positioned and connected even on a ground that is not completely horizontal. It can be added that: when multiple transport vehicles are connected and positioned along the left-right direction, the connected transport vehicles can still move (separate), but since the display screen is provided with a quick locking mechanism that locks adjacent screens together, the stability between the multiple transport vehicles can be guaranteed; this is not the focus of the present application and will not be described in detail again.

[0040] Preferably, a support frame 40 is provided on the upper side of the first side door 20 and the second side door 30 to support the transport vehicle above; thus, when the transport vehicle is equipped with multiple display screens, they can also be stored and transported in a stacked manner.
