Detachment-free oil drainage bolt

Abstract

The invention discloses a detachment-free oil drainage bolt, which comprises a valve body, a plug valve core and an oil drainage device. The valve body also serves as an oil drainage bolt and is provided with an external thread, a valve body oil inlet and a valve body oil outlet; the plug valve core is mounted in an inner cavity of the valve body and provided with a valve core oil inlet channel; a valve core oil outlet channel communicated with the valve core oil inlet channel is also arranged in the plug valve core; the valve core oil outlet channel is communicated with the valve body oil outlet; a valve core sealing device is arranged between the plug valve core and the valve body; the oil drainage device comprises an oil drainage pipe inserted into the valve body oil outlet; the oil drainage pipe is provided with an oil drainage channel communicated with the valve core oil outlet channel; a valve core opening device is arranged between the oil drainage pipe and the plug valve core;and an oil drainage pipe inserting / fixing device is also arranged between the oil drainage pipe and the valve body. The oil drainage pipe drives the plug valve core to rotate through the valve core opening device, the valve body oil inlet is opened, and the waste oil enters the valve core oil outlet channel through the valve core oil inlet channel from the valve body oil inlet and then flows out through the oil drainage pipe. Through the invention, the waste oil is prevented from spattering around, and the pollution is reduced.

Description

technical field [0001] The invention relates to an oil drain bolt. Background technique [0002] The main functions of engine oil include: lubrication, sealing, heat dissipation and rust prevention. The condition of the engine oil directly affects the performance and life of the engine, so it must be replaced in time. [0003] When the engine is working, under high temperature, high speed, high speed and irregular changes, metal debris generated by the friction of various parts, dust intruded from the air, acidic substances generated by combustion, and some fuel that has not been completely burned are mixed into the engine oil, making the engine oil Viscosity decreases; part of the exhaust gas from the combustion chamber enters the crankcase and brings in components such as acid anhydride to deteriorate the engine oil, making it unable to achieve its proper function, which will affect the working efficiency and life of the engine. Therefore, after a certain mileage, the eng...

[0003] When the engine is working, under high temperature, high speed, high speed and irregular changes, metal debris generated by the friction of various parts, dust intruded from the air, acidic substances generated by combustion, and some fuel that has not been completely burned are mixed into the engine oil, making the engine oil Viscosity decreases; part of the exhaust gas from the combustion chamber enters the crankcase and brings in components such as acid anhydride to deteriorate the engine oil, making it unable to achieve its proper function, which will affect the working efficiency and life of the engine. Therefore, after a certain mileage, the engine oil must be replace

[0004] When changing the engine oil, it is necessary to place a waste oil container under the oil pan, slowly unscrew the oil drain bolt, and the waste oil will flow out from the oil drain hole. During the above process, the waste oil is easy to splash and cause pollution
