The invention discloses an integrated concentric gun-jumping-preventing oil filling pipe which comprises an oil filling pipe body and an anti-overflow sleeve, an oil filling port is coaxially and integrally formed in the oil filling end of the oil filling pipe body in an expanding mode, a port of the oil filling port is turned outwards to form a sealing protection ring, and the sealing protection ring is composed of a first R arc section, a conical sealing section, a second R arc section and a tail section which are sequentially connected. A double-end internal thread is formed in the oil filling port in a stamping manner, and the distance between the starting point of the double-end internal thread and the top of the sealing protection ring is 6.25 mm; the anti-overflow sleeve is coaxially welded in the oil filling opening, an oil filling gun opening allowing a gun head of an oil filling gun to be inserted is eccentrically formed in the bottom of the anti-overflow sleeve, and the distance between the top of the anti-overflow sleeve and the top of the sealing protection ring is 25.92 mm. The oil gun is resistant to abrasion, resistant to static electricity, smooth in oil filling, capable of better adapting to various gun inserting angles and depths and capable of meeting the using requirement of vehicle oil filling.
