Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and more specifically to a novel quick-insertion connector for externally connecting an automobile oil inlet and return pipe. Background Art

[0002] Most cars now have a return oil pipe. After the fuel pump supplies fuel to the engine and forms a certain pressure, in addition to the normal supply to the fuel nozzle for fuel injection, the remaining fuel is sent back to the fuel tank through the return oil pipe. Of course, the excess gasoline vapor collected in the carbon canister also returns to the fuel tank through the return oil pipe. The return oil pipe can return excess oil to the fuel tank, which can relieve the pressure of gasoline and reduce fuel consumption.

[0003] The utility model patent with announcement number CN214093488U discloses a quick-connect connector for external automobile oil inlet and return pipes. The basic existing connection method is to remove the oil inlet and return pipes from the automobile tank end and then connect them to the pipes of the test equipment. However, the connection method is relatively complicated, and sometimes the operation is very complicated due to the small space. The above utility model can facilitate the disassembly and cleaning of the connector through a telescopic button, and the device can seal the connector through an elastic ball and a rubber ring. The quick-connect connector has a simple structure, is easy to use, and has high reliability, and can improve the test efficiency to a certain extent.

[0004] However, in actual use, after the fuel is returned, when the connector is pulled out, the residual fuel between the connectors will leak out from the fuel inlet pipe. When connecting the fuel inlet pipe, the plugging and unplugging will cause shaking, which may cause leakage when transporting fuel. Utility Model Content
