AI Technical Summary

Benefits of technology

[0008]Embodiments of the present invention provide a drain cock of an engine oil pan for a vehicle that can prevent the engine oil from leaking due to the wear and tear of a screw thread of the drain cock. Embodiments of the present invention further may provide a receptacle that enables the drain cock to be inserted in and drawn out of the engine oil pan in a drawer type and providing a nut cap for opening and closing oil to be inserted into a drain hole of the engine oil pan using a bolt and a spring.

[0010]As an exemplary embodiment, a rubber gasket is attached to the bottom of the nut cap to prevent an oil leakage.

Problems solved by technology

However, conventional drain cocks have some drawbacks in that the screw portion of the drain cock may be damaged by an excessive torque applied when exchanging the oil or the screw portion may be worn and torn to leak the engine oil through the drain cock, thus contaminating the engine oil pan.

Moreover, the leakage of the engine oil may cause serious problems in that the entire engine is damaged and the vehicle including the damaged drain cock breaks down, thus increasing the operation of repairing the vehicle and, accordingly, deteriorating the working efficiency.
