The invention discloses an anti-theft oil drain opening of a locomotive fuel tank. An oil drain opening which needs to be protected is formed in a fuel-tank end plate, and an annular screw holder is vertically welded to the outer side of the oil drain opening, on the fuel-tank end plate; an arc-shaped clamping plate is arranged on the outer side of the screw holder and vertically welded to the fuel-tank end plate; clamping plate holes are symmetrically formed in two free ends of the clamping plate; the minimum distance from each clamping plate hole to the fuel-tank end plate is larger than the height of the screw holder; a bowl-shaped cover plate is mounted in the arc-shaped clamping plate and concentric with the arc-shaped clamping plate; cover plate holes are respectively formed in positions corresponding to the clamping plate holes, in the bowl-shaped cover plate; a lock rod penetrates through the clamping plate holes and the cover plate holes; a lock rod head is arranged at one end of the lock rod, and the diameter of the lock rod head is larger than that of each clamping plate hole and that of each cover plate hole; a lock hole is formed in the other end of the lock rod; a lock is arranged in the lock hole; a screw plug is also arranged in the screw holder. The anti-theft oil drain opening is simple in structure, and convenient to mount, and can effectively prevent fuel from being stolen.
