Abstract
The invention discloses a double-layer automobile anti-theft oil tank which comprises an oil tank outer layer and an oil tank inner layer, wherein an oil filling port which is communicated into an interlayer formed by the oil tank outer layer and the oil tank inner layer is formed in the top end of the oil tank outer layer; the bottom end of the inner layer of the oil tank is provided with a one-way valve for fuel oil to enter the inner layer of the oil tank from the interlayer; and the upper part of the inner layer of the oil tank is provided with an air vent for the air in the inner layer of the oil tank to flow into the interlayer. The double-layer automobile anti-theft oil tank can effectively prevent an oil thief from completely stealing fuel oil in the oil tank even if the oil suction pipe is inserted into the interlayer of the oil tank from the oil filling opening of the oil tank, and provides an oil-free false image for the thief when the fuel oil in the interlayer is completely pumped out, thereby better ensuring the safety of the fuel oil in the oil tank. The anti-theft device has the advantages of simple structure, strong anti-theft performance, safety, firmness, reliability and the like, and is suitable for various machines and vehicles with oil tanks.
Description
Technical Field
The invention belongs to the technical field of automobile fuel tanks, and particularly relates to a double-layer type automobile anti-theft fuel tank.
Background
After the fuel oil in the automobile fuel tank is stolen, not only great economic loss is brought, but also the automobile is difficult to continue to run midway. The oil tanks containing more oil are arranged outside the general large-scale truck, and the oil inside the large-scale truck is easily stolen by people due to the absence of an anti-theft device, so that the anti-theft oil tank which can prevent theft and can smoothly refuel is needed to be designed.
Disclosure of Invention
Based on the defects of the prior art, the technical problem to be solved by the invention is to provide a double-layer automobile anti-theft fuel tank, which adopts a double-layer structure, can effectively prevent a fuel thief from stealing fuel in the fuel tank by using an oil suction pipe, does not influence refueling, and has the advantages of simple structure, strong anti-theft performance, safety and firmness.
In order to solve the technical problems, the invention is realized by the following technical scheme: the invention provides a double-layer automobile anti-theft oil tank which comprises an oil tank outer layer and an oil tank inner layer, wherein the top end of the oil tank outer layer is provided with an oil filling port which is communicated into an interlayer formed by the oil tank outer layer and the oil tank inner layer;
the bottom end of the inner layer of the oil tank is provided with a one-way valve for fuel oil to enter the inner layer of the oil tank from the interlayer;
and the upper part of the inner layer of the oil tank is provided with an air vent for the air in the inner layer of the oil tank to flow into the interlayer.
Further, an oil outlet communicated with the interlayer is formed in the bottom end of the outer layer of the oil tank.
Therefore, the double-layer automobile anti-theft fuel tank can effectively prevent a fuel stealer from being incapable of completely stealing fuel in the fuel tank even if the fuel oil stealer inserts the fuel oil pipe into the fuel tank interlayer from the fuel filling opening of the fuel tank, and provides the stealer with an oil-free false image when the fuel oil in the interlayer is completely pumped out, thereby better ensuring the safety of the fuel oil in the fuel tank. The anti-theft device has the advantages of simple structure, strong anti-theft performance, safety, firmness, reliability and the like, and is suitable for various machines and vehicles with oil tanks.
The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented in accordance with the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more clearly understood, the following detailed description is given in conjunction with the preferred embodiments, together with the accompanying drawings.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings of the embodiments will be briefly described below.
FIG. 1 is a schematic overall structure diagram of a double-layer type automobile anti-theft fuel tank according to a preferred embodiment of the invention;
FIG. 2 is a half sectional view of the double-layer type automobile anti-theft fuel tank of the present invention;
FIG. 3 is a cross-sectional view A-A of FIG. 2;
fig. 4 is an enlarged view at B in fig. 3.
In the figure, 1-the outer layer of the oil tank, 2-the oil filling port, 3-the inner layer of the oil tank, 4-the one-way valve, 5-the oil outlet and 6-the vent hole.
Detailed Description
Other aspects, features and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which form a part of this specification, and which illustrate, by way of example, the principles of the invention. In the referenced drawings, the same or similar components in different drawings are denoted by the same reference numerals.
As shown in figures 1 to 4, the double-layer automobile anti-theft oil tank comprises an oil tank outer layer 1, an oil filling port 2, an oil tank inner layer 3, a one-way valve 4, an oil outlet 5 and a vent hole 6, wherein the oil filling port 2 extends into an interlayer formed by the oil tank outer layer 1 and the oil tank inner layer 3, the oil tank outer layer 1 and the oil tank inner layer 3 are communicated through the one-way valve 4 arranged at the lower part of the oil tank inner layer 2, the communication direction of the one-way valve 4 only allows fuel oil to enter the oil tank inner layer 3 from the interlayer, and the vent hole 6 is arranged at the upper part of the oil tank inner layer 3 and is communicated with.
The oil filling port 2 of the invention is introduced into an interlayer formed by the outer layer 1 of the oil tank and the inner layer 3 of the oil tank, the liquid level in the interlayer is higher than the liquid level of the fuel in the inner layer 3 of the oil tank when oil is filled, pressure difference is generated between the fuel in the interlayer and the fuel in the inner layer 3 of the oil tank, the fuel backs up the one-way valve 4 to flow into the inner layer 3 of the oil tank, and the air in the inner layer 3 of the oil tank flows into the interlayer through the vent hole. As the fuel is used less and less, the fuel in the sandwich will continue to be replenished into the tank inner layer 3 through the non-return valve 4.
When an oil thief inserts an oil suction pipe into the interlayer of the oil tank from the oil filling port 2 of the oil tank to suck oil, fuel oil in the interlayer is quickly drained, the fuel oil in the inner layer 3 of the oil tank cannot flow back into the interlayer through the one-way valve 4, and the sound of an empty oil tank can be generated when the oil tank is knocked, so that the safety of the fuel oil in the oil tank is protected.
While the foregoing is directed to the preferred embodiment of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
