Oil filling nozzle with high accuracy of gun tripping during oil filling

Abstract

The invention discloses an oil filling nozzle with high accuracy of gun tripping during oil filling. The oil filling nozzle comprises a first pipe body, a second pipe body, a third pipe body and a fourth pipe body, wherein the first pipe body, the second pipe body, the third pipe body and the fourth pipe body are connected withgether; the pipe wall of the third pipe body sinks inwards to form a structure with large two ends and a small middle part, the structure is used for limiting the shaking of an oil gun, and the lower part of the pipe wall of the third pipe body is provided with exhaust holes; an anti-bubble structure is arranged on the lower part of the inner wall of the fourth pipe body, and the anti-bubble structure comprises a rubber cone, a circular-truncated-cone-shaped spring and a fixed ring; and the fixed ring is fixedly connected with the bottom of the inner wall of the fourth pipe body, and the bottom of the rubber cone is connected with the fixed ring through the circular-truncated-cone-shaped spring. According to the oil filling nozzle with high accuracy of gun tripping during oil filling, due to the arrangement of the anti-bubble structure, when fuel oil enters the fourth pipe body, the fuel oil impacts the top of the rubber cone and flows downwards along the conical surface of the rubber cone, the liquid flow is dispersed, the impact force on the fuel liquidsurface is greatly weakened, a large amount of bubbles are avoided, the situation that the oil gun is tripped in advance is avoided, and the accuracy of gun tripping is improved.

Description

Technical field [0001] The invention relates to automobile parts, in particular to a fueling nozzle with high accuracy of fueling a gun. Background technique [0002] With the development of society, people's living standards are constantly improving. At present, most people have cars in their homes, and cars have become the most commonly used means of transportation. Among them, fuel vehicles are the mainstream products in the current automotive market, and they need to be filled with fuel to drive normally. [0003] The fuel nozzle (also known as the diversion port) is a part of the car used to cooperate with the fuel nozzle of the gas station. When refueling, the fuel nozzle is inserted into the fuel nozzle, and gasoline is injected into the fuel pipe connected to the fuel tank to realize the fuel tank refueling. When the fuel nozzle is used to inject fuel into the fuel tank of a car, because the flow rate of the fuel is relatively fast, a large number of bubbles will be genera...

Problems solved by technology

But at this time, the fuel tank is not actually full, and there is still more space to store fuel. Some drivers like to fill up the fuel tank completely. At this time, the staff at the gas station need to manually control the refueling gun to continue refueling. The method often causes the fuel to be full due to improper manual control, which not only causes waste, but also is unsafe and may cause a fire

The above problems can be attributed to the low accuracy of refueling and jumping guns
