• The lid is interlocked with the inner edge in a closed state to form a double lock, which will not loosen even during bumpy handling or tilted placement. When opening, it is necessary to clarify the direction of force application to avoid accidental ejection due to collision or vibration, reduce the risk of fuel leakage, and be particularly suitable for storage in garages, trailers, or during transportation.
• The bottom edge of the lid is equipped with a micro concave guide groove. When there is a small amount of overflow during the refueling process, the liquid can flow back to the inside of the refueling port along the groove instead of overflowing onto the surface of the vehicle. This detail effectively prevents oil stains from contaminating hands, clothing, or equipment casings, keeping the work environment clean and reducing cleaning frequency.
• After opening the lid, limit it to within 120 degrees, ensuring sufficient space to insert the oil drum and preventing excessive expansion that could cause collision or deformation between the lid and the body. This design is particularly practical in narrow spaces such as tool sheds and forest clearings, avoiding being forced to operate due to limited operating space.
• The contact surface between the lid and the fuel tank port is equipped with an elastic sealing structure, which not only prevents fuel evaporation, but also prevents oil from flowing back to the refueling port through the gap when the equipment is tilted or parked on a slope, avoiding oil accumulation, impurity breeding, or odor generation at the refueling port, and extending the oil circuit cleaning cycle.
