[0004] To overcome these shortcomings, the market urgently needs a mobile fuel nozzle with a simple structure, convenient operation, and reasonable cost, while ensuring stable and safe refueling. This nozzle needs to be able to adapt to refueling needs at different angles and positions, and also needs to prevent oil backflow and leakage to ensure a smooth refueling process and ensure oil quality. Utility Model Content
[0005] The present utility model aims to provide a mobile refueling gun that addresses the problems identified in the aforementioned background art. This gun, through a refueling gun body mounted on a manipulator and a movable refueling gun head, combined with components such as a fuel delivery hose and a check valve, automates and intelligentizes the refueling process. Furthermore, the use of a retractable elastic member ensures the stability of the refueling gun head during movement, further improving refueling accuracy and safety.

[0022] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0023] See also Figure 1 A mobile refueling gun includes a refueling gun body 1 mounted on a manipulator, a refueling gun head 2 movably mounted on the refueling gun body, an oil delivery hose 3 installed in the refueling gun body, one end of the oil delivery hose is connected to the oil supply device, and the other end of the oil delivery hose is connected to the oil inlet of the refueling gun head, a check valve 4 is installed at the end of the oil delivery hose close to the refueling gun head, and the refueling gun body and the refueling gun head are connected by a telescopic elastic member 5.
[0024] The retractable elastic member 5 is a correction spring, one end of which is connected to the fueling nozzle body and the other end to the fueling nozzle head. The fuel hose 3 is coaxially threaded within the correction spring. This not only ensures the stability of the fueling nozzle head during movement, but also allows for flexible adjustment of its position and angle according to actual needs. Furthermore, the coaxial threading of the fuel hose within the correction spring reduces friction and wear during movement, further improving refueling accuracy and stability.
[0025] As a preferred embodiment, a dust removal port 6 is installed on the fuel gun body, corresponding to the fuel inlet. This port is connected to the air source via a pipe 7, which is equipped with a dust removal valve. This allows the fuel inlet to be purged before refueling, effectively removing dust and impurities, improving refueling cleanliness and safety. This design is particularly suitable for mechanical equipment and working environments with high cleanliness requirements. Furthermore, multiple dust removal ports can be designed around the axis to ensure comprehensive dust removal coverage.
[0026] As a preferred embodiment, the end of the fueling nozzle is equipped with a conical portion 8 for centering. This conical portion 8 facilitates quick and accurate centering of the nozzle with the fuel filler port during refueling, reducing inaccurate refueling or oil leaks caused by inaccurate centering. This design improves refueling efficiency and accuracy.
[0027] As a preferred embodiment, a holder 9 is mounted on the back of the fueling gun body, which is equipped with a slot 10 for the manipulator. This allows the fueling gun to be easily mounted on the manipulator and securely connected to the manipulator via the slot. Furthermore, the fueling gun head is detachably mounted on the fueling gun body via a threaded connection, facilitating subsequent maintenance and replacement, reducing maintenance costs.
[0028] As a preferred embodiment, the fuel gun head is detachably mounted to the fuel gun body via threads. This threaded connection allows for easy removal from the gun body, making it extremely convenient for routine maintenance and upkeep. If the fuel gun head becomes worn, clogged, or needs replacement, the operator simply unscrews it for cleaning, repair, or replacement, eliminating the need for complex disassembly of the entire fuel gun, significantly improving maintenance efficiency. The detachable threaded connection allows the fuel gun head to be replaced based on varying refueling needs. For example, for fuel inlets of different sizes or types, the appropriate fuel gun head can be selected for installation, ensuring accurate and efficient refueling. This design enhances the flexibility and adaptability of the fuel gun, enabling it to meet a wider range of refueling needs.
