Description
Technical Field
[0001] The utility model relates to the technical field of test boxes, in particular to a portable refueling test box. Background Art
[0002] Currently, software engineers, test engineers, and after-sales trainers at gas stations need to simulate the working principles of a full-scale refueling machine to meet certain work requirements. This is typically accomplished using a test box equipped with a refueling simulation system and an operating interface and buttons similar to those found on a refueling machine. This test box can be used for refueling software testing, refueling commissioning, and employee training. This test box eliminates the need to install a full refueling machine or conduct on-site commissioning or testing. Simulated refueling commissioning and testing can be performed anywhere, significantly improving work efficiency.
[0003] However, the conventional test box is bulky to carry and has a single structure. When the box is opened for testing or debugging, it needs to be placed in a location with a wall or other support. The flipped side of the box needs to be supported by a wall, which is very inconvenient, limits the place of use and poses a safety hazard. Utility Model Content

The box body is provided with multiple mounting holes, and the mounting pins are detachably connected to the mounting holes. The adjusting rod adjusts the opening angle of the box lid by cooperating with the mounting pins and different mounting holes.
[0013] As a preference, the handle includes a first handle and a second handle, the first handle is arranged on a side opposite to the universal wheel assembly, and the second handle is arranged on a side of the box adjacent to the universal wheel assembly.
