Abstract

The invention discloses an oil tank cover structure with a good sealing effect. The oil tank cover structure comprises a lock framework and a lock plate. A lock sleeve is arranged between the lock framework and the lock plate. A lock cylinder and a lock cylinder sleeve are arranged in the middle of the lock framework. Lock cylinder springs and lock cylinder outer balance springs are arranged on the outer side of the part, at the lower end inside the lock cylinder sleeve, of the lock cylinder. The lock framework is connected with the lock cylinder sleeve through a first fixing bolt. The lock framework, the lock sleeve and the lock plate are connected through a second fixing bolt. A locking clamping device is movably arranged between the lock plate and the lower end of the lock framework and sleeved with locking clamping springs. The locking clamping device is formed by matching three locking clamps. Lock holes matched with the lower end of the lock cylinder are formed between the three locking clamps. A keyhole is formed in the upper end of the lock cylinder. A lock pin hole is formed in the upper end of the lock cylinder. A lock pin is arranged in the lock pin hole. The lock cylinder sleeve is provided with an L-shaped lock pin locating groove matched with the lock pin.

Description

technical field [0001] The invention relates to a fuel tank for an internal combustion engine multiple train set, in particular to a fuel tank cover structure for the fuel tank of an internal combustion engine multiple train set. Background technique [0002] With the continuous advancement of science and technology, EMUs have become the main means of transportation for Chinese residents to travel by train. The existing EMUs mainly use coal and electricity as power. Coal is used as power. Waste of energy will cause pollution. Electricity is used as power. Electricity needs to be erected, and the basic investment is relatively large, so it cannot be used in areas with insufficient electricity. Therefore use internal-combustion engine power EMU in some areas, the power of internal-combustion engine adopts fuel oil to provide, and fuel tank is provided with fuel filler, is provided with fuel tank cover on fuel filler, and existing fuel tank clearing sealing effect is not good, ...
