Description

Technical Field

[0001] The utility model relates to the technical field of fueling gun appliances, in particular to a high-strength and corrosion-resistant fueling gun body. Background Art

[0002] The fuel gun is the output terminal of the fuel pump in the gas station, that is, the part that contacts the car's fuel tank. The appearance of an ordinary fuel gun is mainly composed of the fuel gun body, hand guard, limit plate, switch handle, baffle, automatic control rod and other parts. The limit plate is fixed on the fuel gun hand guard. The limit plate has three gears. When the switch handle is turned on, the baffle can be tilted 45 to 60 degrees and fixed on the limit plate. It also fixes the opening of the fuel gun switch to control the amount of oil output from the fuel pump.

[0003] Chinese patent publication number CN208135894U discloses a fuel gun body that can be manufactured using a pressure casting process to improve the surface quality of the gun body. The fuel gun body includes a first oil and gas recovery channel that is a straight hole, with the first end of the first oil and gas recovery channel opening at the front end of the gun body, and the second end of the first oil and gas recovery channel communicating with the control valve assembly mounting cavity; a second oil and gas recovery channel that is also a straight hole, with the first end of the second oil and gas recovery channel communicating with the control valve assembly mounting cavity, the second end of the second oil and gas recovery channel communicating with the main valve assembly mounting cavity, and the second end of the second oil and gas recovery channel facing the upper end of the main valve assembly mounting cavity; and a third oil and gas recovery channel that is also a straight hole, with the first end of the third oil and gas recovery channel communicating with the main valve assembly mounting cavity, and the second end of the third oil and gas recovery channel facing the rear end of the gun body.

[0004] In the above application, a pressure casting process is used to manufacture the gun body, which includes oil and gas recovery channels, main valve components and other components to form the entire fueling gun. Multiple oil and gas recovery channels are relatively adapted to achieve the same oil and gas recovery effect. During use, the gun body is soaked in oil and oil stains for a long time, which can easily cause internal corrosion of the gun body and thus damage the fueling gun body. In addition, during the refueling process, there is no mention of the corresponding components regarding the prompt problem after the oil is full. Therefore, the fueling gun body needs further improvement in terms of corrosion resistance and oil full prompt problem. Utility Model Content
