The embodiment of the utility model discloses a fuel tank anti-theft structure, which is shown in figure 1 and comprises a fuel tank body 1 and a refueling device 2 arranged on a refueling port of the fuel tank body 1.

Specifically, the refueling device 2 includes a first cylinder 21 provided inside the fuel tank body 1 and open at both ends, and a second cylinder 22 provided outside the first cylinder 21 and open at the upper end; the first cylinder 21 is communicated with the oil filler of the fuel tank body 1; the upper end of the second cylinder 22 is located above the lower end of the first cylinder 21, and forms an oil inlet passage with the inside top surface of the fuel tank body 1.

When the fuel tank of the embodiment is refueled, when the fuel gun refuels the fuel tank body 1 through the fuel filler opening of the fuel tank body 1, the fuel flows into the second cylinder 22 through the first cylinder 21, and flows into the fuel tank body 1 through the fuel inlet channel formed between the second cylinder 22, the first cylinder 21 and the inner top surface of the fuel tank body 1; when the impure person tries to steal the oil, the impure person cannot extend the oil suction pipe into the fuel tank body 1 because the upper end of the second cylinder 22 is positioned above the first cylinder 21, so that the anti-theft effect is realized; and compared with the filter screen, the anti-theft structure has the advantage of higher oiling speed.

In some embodiments, the first barrel 21 extends downwardly from the rim of the filler neck of the fuel tank body 1; the second barrel 22 is welded into a whole through a plurality of connecting rods 23 which are uniformly arranged along the circumferential direction of the upper end of the second barrel 22 and the fuel tank body 1, and the purpose is that an impure person can hardly dismantle the oiling device 2 and is fixedly connected through the connecting rods 23, so that the influence on the fuel flow is effectively reduced, and the oiling speed is improved.

It can be understood that, for convenience in processing and production, the second cylinder 22 may be connected and fixed to the first cylinder 21 through a plurality of connecting rods 23; the first cylinder 21 is integrally connected with the fuel tank body 1 by welding, so that the first cylinder 21 and the second cylinder 22 can be integrally processed and then integrally welded in the fuel tank body 1.

In some embodiments, to increase fueling rate, the second barrel 22 is tapered with a large top and a small bottom.

More specifically, as shown in fig. 2, a plurality of fine through holes 221 are distributed on the sidewall of the second cylinder 22 so that fuel can flow into the fuel tank body 1 through the through holes 221 during refueling to increase a refueling speed.

As a specific implementation of the above embodiment, the cross section of the first cylinder 21 and the second cylinder 22 is preferably circular.

The fuel tank body 1 and the oiling device 2 are both made of aluminum alloy.

As can be seen from the above description, the working principle and the beneficial effects of the embodiment of the utility model are as follows:

when the fuel gun charges fuel to the fuel tank body 1 through the fuel charging port of the fuel tank body 1, fuel flows into the second cylinder 22 through the first cylinder 21, and flows into the fuel tank body 1 through the fuel charging channel formed by the second cylinder 22 and the outer wall of the first cylinder; when the impure person tries to steal the oil, the impure person cannot extend the oil suction pipe into the fuel tank body 1 because the upper end of the second cylinder 22 is positioned above the first cylinder 21, so that the anti-theft effect is realized, and the oil filling speed is higher than that of the filter screen; further, the second cylinder 22 and the fuel tank body 1 are welded together through a plurality of connecting rods 23, and the first cylinder 21 is formed by extending downwards from the edge of the oil filling port of the fuel tank body 1 or is fixedly connected with the fuel tank body 1 through welding, so that the first cylinder 21, the second cylinder 22 and the fuel tank body 1 are connected into a whole, and are not easy to damage; finally, the second cylinder 22 is tapered with a large top and a small bottom, and a plurality of through holes are formed in the side wall of the second cylinder 22, so that the oiling speed is improved.

The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the utility model, and is not meant to limit the scope of the utility model, but to limit the utility model to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the utility model are intended to be included within the scope of the utility model.
