Description

Technical Field

[0001] This utility model relates to the field of refueling truck technology, specifically to a sinking observation box for an aircraft refueling truck. Background Technology

[0002] A fuel truck is a vehicle that transports oil products. Fuel trucks are equipped with mobile refueling machines to deliver fuel to receiving equipment such as vehicles, agricultural machinery, boilers, construction machinery, and hotels.

[0003] Aircraft refueling trucks need to periodically drain fuel from their auxiliary fuel tanks or filter settling tanks. The fuel is discharged from the refueling truck's drain port through an external hose into a recovery tank.

[0004] According to Chinese patent CN219257702U, a sinking observation box for an aircraft refueling truck can filter aircraft fuel through a filter assembly. By opening the top cover to observe whether there are impurities in the filter screen, the quality of the aircraft fuel can be judged to ensure equipment safety. Through the setting of the locking assembly, the top cover can be removed in two ways. The first way is to remove it directly, and the second way is to use it in conjunction with the release assembly. By holding the handle with both hands and pressing the limit block with the palm, the push rod is driven to slide downward, so that the push rod slides inside the ramp, thereby driving the protrusion to slide into the mounting groove. At this time, the protrusion disengages from the groove, and the top cover can be removed.

[0005] The aforementioned device is not secure enough when limiting the top cover, and it is prone to loosening and falling off. Furthermore, the filter frame does not have a limiting structure, which makes the filter screen prone to shaking inside the observation box, thus affecting the observation effect. Therefore, a sinking observation box for an aircraft refueling truck is proposed to solve the above problems. Utility Model Content
