[0002] The apron refueling hose is a special hose for fuel delivery to the aircraft on the airport apron, which is mainly made of rubber and other materials with good oil resistance and weather resistance. This is because the aircraft fuel has specific chemical properties, and ordinary materials are easily corroded. Rubber material can resist the corrosion of fuel, ensure that the hose will not be damaged in the process of long-term contact with fuel, and ensure the safety and stability of fuel delivery.

[0003] At present, in the prior art, the traditional apron refueling hose drag mechanism has many defects. In terms of fixing the hose, most of them use simple clamping or binding methods. The clamping method often relies on rigid clamps. Such clamps are difficult to adapt to the needs of hoses of different diameters. For small diameter hoses, it may cause excessive extrusion and damage the hose. For large diameter hoses, it cannot provide enough clamping force, which can easily cause the hose to shift or even unhook during dragging or refueling. In view of this, we propose a drag mechanism of apron refueling hose of anti -unhooking. CONTENT OF THE UTILITY MODEL
